My Austro-Daimler 'Vent Noir II' Bicycle And Brief History of Steyr Daimler Puch The Sasha was followed in 1923 by the successful ADM, a luxury car and quite a successful accomplishment by the days standards. The ADM was the first of the post-Porsche models, designed by the team led by Karl Rabe. Rabe followed the ADM with the ADR, the first of which incorporate a 2.54 litre 6 cylinder overhead cam engine; the R indicates this is built upon a Rohrrahmen (tubular frame) a stepping away from the Plattformrahmen (platform frame) arrangement as provided with its predecessors. Then just before the ADR cars came onto the market in 1927 however, Rabe was hired away by Porsche to work at his company. Rabe would remain employed at Porsche until shortly before his death in 1968. Left: Austro Daimler ADR of 1924 (71,705 bytes).

To mold the aluminum alloy into a bike frame, the metal goes through a recently invented process called hydroforming. Once the hydroforming is complete, and all the tubes have been molded into the appropriate shapes, the tubes are welded together and smoothed with sanding, thus producing a sturdy bicycle frame.

The original ADR autos would be followed by variants including the ADM 19/100 'Harrington Tourer', a 100 mph capable upscale automobile introduced in 1927. By 1928 Austro Daimler Puchwerke was back in the forefront of automobile technology with racing successes by their comparatively powerful ADM 19/100 model. Technically these cars were highly successful for their day with comparatively high horsepower engines, and efficient cooling mated to a well engineered chassis that provided a superior ride and good road handling manners. The 'ADM' and 'ADV' series motor cars continued to earn the company great acclaim throughout the 1920's, marketed as 'The Car For The Connoisseur'. Even today, some restored Austro Daimler autos win high honors at vintage car shows.

On 31 March 1928 Puch, the Austro Daimler Puchwerke bodywork plant, and Oeffag (the Austrian Aircraft Factory Ltd.) merged. On 28 December 1928 the new company 'Austro Daimler Puchwerke Aktiengesellschaft' was entered in the Vienna register of companies.

After the merger with Austro Daimler Puchwerke the production of automobiles by Puch was ended however, bicycles and motorcycles continued in production then bearing the Puch trademark. Motors continued in production, with engines large enough to power trains being produced bearing the Austro Daimler trade name and the AD logo shown above right.

The Great Depression that commenced in the USA in October 1929 impacted banking, customer demand for commodities, and employment. The crisis spread overseas too so that by 1930 Europe was enveloped by the Great Depression and their markets for the more upscale automobiles were adversely impacted thus causing a dramatic retraction by production throughout the industry. Regardless of the economic situation in 1930, the first of two new luxurious Austro Daimler Puchwerke motor cars were introduced: the ADR 8, which was followed in 1931 by the ADR 6. Both of the ADR cars were well engineered and stylish.

The ADR 8 Alpine features a 4,624 cc (4.6 litre) straight 8 cylinder SOHC gasoline engine producing 121 hp. Some fifty of the ADR 8 were made through the 1935 model year in the customers choice of either a Tourer (2 doors, 2+2 seating with a retracting top), or a Limousine (4 doors and 4 seats), a Cabriolet (2 doors, 2 seats convertible), or Saloon (4 doors, 4 seats). The ADR 6 Bergmeister, introduced in 1932, was a lighter weight model at about 3,200 lbs. Even with its 3,613 cc (3.6 litre) straight 6 in line SOHC engine, the ADR 6 was faster and with a 94 mph top speed, and better at climbing hills (hence 'mountain master') than the ADR 8. The ADR 6 was offered as Cabriolet, Tourer, or Saloon configuration with about fifty of these being completed.

These were the last great civilian motor cars introduced under the Austro Daimler Puchwerke trademark. The Great Depression had such a long-term impact that Austro Daimler Puchwerke wound down and then suspended all production by 30 June 1934. Austro Daimler Puchwerke then merged with Steyr-Werke AG to form 'Steyr-Daimler-Puch AG'.

This merger was registered in Vienna on 12 October 1934, then on 10 May 1935 the Austro Daimler Puchwerke Aktiengesellschaft (corporation) was delisted from the commercial register. The merger that produced Steyr-Werke AG made this one of the three largest manufacturing concerns in Austria in the 1930's. Right: Steyr-Werke AG trademark (11,137 bytes). While the Depression no doubt limited the demand for the ADR 6 and ADR 8 motor cars they continued to be available into 1935, even after the merger with Steyr. After the ADR production stopped in 1935, all automobile production by Austro Daimler Puchwerke was ended as the facilities transitioned solely to the production of motors, and trucks as large as the a 6x6 (six wheel drive) chassis, lorries (small towing or personnel carrying trucks), motorcycles, and of course bicycles. While Steyr continued with the production of consumer and military passenger vehicles and trucks. Left: Steyr-Daimler-Puch head badge from a 'Silver Wheel' bicycle made after 1934 (21,206 bytes).

After the merger of 1934, their bicycles were marketed under either the Austro Daimler or Puch trade names though they may bear 'Steyr-Daimler-Puch Aktiengesellschaft' or 'Steyr-Daimler-Puch AG' engraved on the head badge, and this was embossed on some accessories too. The motorcycles manufactured for the consumer market were assembled at the factory in Graz and after the merger were marketed under the Puch trade name. The economic situation of many people in Europe was still not good owing to the residual effects of The Depression.

So there were markets for more affordable modes of transportation, the Volkswagon for example came about in response to this perceived demand. So when Puch attended the Vienna International Spring Fair in March of 1938 they revealed their vision of economical two wheel motor transport, then selling for only 390 Austrian Shillings: the Puch STYRIETTE. The Styriette resembles a motorized bicycle, it features a lightweight lugged and brazed steel frame riding on 26 inch wheels, both with drum brakes, and incorporating an 60 cc 1.3 hp two-stroke air-cooled engine (that consumed only 1.5 liters of gasoline per 100 km) and with pedals too; these would become known to the world as the Moped. It was of particular interest to those aged 16 or less since the law demanded no liability insurance or drivers license to operate the Styriette. Some 2,300 or so of these innovative machines were manufactured before international events would override Steyr Daimler Puch in the Spring of 1938, and production of the Styriette halted. Of course production of motorcycles continued too including their flagship Type 350 GS.

In 1936 Puch introduced its largest motorcycle, the Puch 800, a 430 lb four-speed model powered by a 20 HP four cylinder four stroke 792 cc motor; some 550 or so of these would me made into 1938.

RECENT NEWS: • •, once we build it • Ralph Merkle's from. The next few paragraphs provide a brief introduction to the core concepts of nanotechnology, followed by links to further reading. Manufactured products are made from atoms. The properties of those products depend on how those atoms are arranged. If we rearrange the atoms in coal we can make diamond. If we rearrange the atoms in sand (and add a few other trace elements) we can make computer chips.

If we rearrange the atoms in dirt, water and air we can make potatoes. Todays manufacturing methods are very crude at the molecular level. Casting, grinding, milling and even lithography move atoms in great thundering statistical herds. It's like trying to make things out of LEGO blocks with boxing gloves on your hands. Yes, you can push the LEGO blocks into great heaps and pile them up, but you can't really snap them together the way you'd like. In the future, nanotechnology (more specifically, molecular nanotechnology or MNT) will let us take off the boxing gloves. We'll be able to snap together the fundamental building blocks of nature easily, inexpensively and in most of the ways permitted by the laws of nature.

This will let us continue the revolution in computer hardware to its ultimate limits: molecular computers made from molecular logic gates connected by molecular wires. This new pollution free manufacturing technology will also let us inexpensively fabricate a cornucopia of new products that are remarkably light, strong, smart, and durable. 'Nanotechnology' has become something of a buzzword and is applied to many products and technologies that are often largely unrelated to molecular nanotechnology. While these broader usages encompass many valuable evolutionary improvements of existing technology, molecular nanotechnology will open up qualitatively new and exponentially expanding opportunities on a historically unprecedented scale. We will use the word 'nanotechnology' to mean 'molecular nanotechnology'.

Nanotechnology will let us: • Achieve the ultimate in precision: almost every atom in exactly the right place. • Make complex and molecularly intricate structures as easily and inexpensively as simple materials. • Reduce manufacturing costs to little more than the cost of the required raw materials and energy. While technologies that lack one or more of these characteristics can be quite valuable, by definition they are not molecular nanotechnology. Molecular nanotechnology will let us build new and entirely novel molecular machines, like the illustrated at left. Molecular nanotechnology will be the physical foundation for the.

There are two more concepts commonly associated with nanotechnology: •. Clearly, we would be happy with any method that simultaneously achieved the first three objectives. However, this seems difficult without using some form of positional assembly (to get the right molecular parts in the right places) and some form of massive parallelism (to keep the costs down). The need for positional assembly implies an interest in, e.g., robotic devices that are molecular both in their size and precision. These molecular scale positional devices are likely to resemble very small versions of their everyday macroscopic counterparts because both the macroscopic and the microscopic versions are trying to achieve the same objectives: the ability to flexibility and accurately hold, position and assemble parts. Positional assembly is frequently used in normal macroscopic manufacturing today, and provides tremendous advantages. Imagine trying to build a bicycle with both hands tied behind your back!

The idea of manipulating and positioning individual atoms and molecules is still new and takes some getting used to. However, as said in a: 'The principles of physics, as far as I can see, do not speak against the possibility of maneuvering things atom by atom.' We need to apply at the molecular scale the concept that has demonstrated its effectiveness at the macroscopic scale: making parts go where we want by putting them where we want. A few robotic arms assembling molecular parts are going to take a long time to assemble anything large — so we need lots of robotic arms: this is what we mean by massive parallelism.

While earlier proposals achieved massive parallelism through, today's 'best guess' is that future molecular manufacturing systems will use some form of. In this process vast numbers of small parts are assembled by vast numbers of small robotic arms into larger parts, those larger parts are assembled by larger robotic arms into still larger parts, and so forth. If the size of the parts doubles at each iteration, we can go from one nanometer parts (a few atoms in size) to one meter parts (almost as big as a person) in only 30 steps.

In this way, a with many robotic arms in it can manufacture another nanofactory in a reasonable period of time. Some Frequently Asked Questions • • • • • • • • • • • More Information Books • The best technical introductions are: • by (Wiley 1992).
