Patent DE-3303509-A1 (DE)
Title: Machines with double-acting pistons
Inventor: NGUYEN TANG SANH DIPL ING
IPC: F01C9/00
Filed: 1983-01-31
Abstract: In these machines, each machine unit (5) has two double-acting pistons connected to one another directly. Similar machines of this kind are described in, inter alia, DE-OS 1601806 or DE-AS 2639450. Since the working spaces are arranged in the form of a circle, it is possible for in each case two valves, situated at any desired angle, to be acted upon via levers by a cam of the cam shaft. The two lines connecting the cam shaft axis and the points of contact between the cam and the lever must form an angle of 90 DEG . The sealing of the working spaces (4) is to be provided between the piston (1) and the cylinder wall (9), the cylinder head (10) and the rotary oscillation hub (6), and the cylinder wall and the rotary oscillation hub. The machine according to the invention can operate without valves by the two-stroke method, using just inlet, exhaust and transfer ports and ducts (18), (19), (35) and (34). In the H-shaped machine, the reciprocating straight-line motion of the piston is converted via at least one joint with two degrees of freedom into the rotary motion of the crank shaft. Machines with double-acting pistons are small in terms of mass and volume, simple in terms of valve timing and have a small number of moving parts and no sealing problems. <IMAGE>

Title: Apparatus for etching metal discs and semiconductor wafers
Inventor: LANDSBERG ELFRIED DIPL ING
IPC: C23F1/08
Filed: 1983-08-31
Abstract: The invention is based on an apparatus for etching metal discs and semiconductor wafers embodying an etching device which comprises a spray nozzle arrangement. In order to be able to etch out comparatively deep regions to obtain very largely cylindrical walls with such an etching apparatus, the spray nozzle arrangement (4) comprises pneumatic atomisation nozzles. During the etching process, the discs or wafers (10) are placed at a distance from the spray nozzle arrangement (4) at which the etchant (3) expelled by the pneumatic spray nozzles has been transformed into an etching mist. The invention can be used, in particular, to produce pressure sensors from semiconductor wafers (Figure 1). <IMAGE>

Title: Fluid kinetic machine with spiral construction
Inventor: SHIIBAYASHI MASAO
IPC: F01C21/04
Filed: 1983-11-17
Abstract: The fluid kinetic machine with spiral construction has a static spiral element and an orbital spiral element, each of which is composed of a disc-shaped end plate and a spiral wall which projects perpendicularly from one side to the corresponding end plate, the assembly being carried out in such a way that the spiral walls interlock. The orbital spiral element carries out an orbital movement relative to the static spiral element in such a way that compression chambers formed between the spiral walls of the two spiral elements progressively move towards the centre, during which process they contract in volume and as a result compress gas, which has been drawn in through an intake opening, and discharge it into an outlet port. The machine has a back-pressure chamber which is formed in the end plate of the orbital spiral element. In this design, a lubricating oil circulation is formed which comprises a lubricating oil channel which leads from an oil reservoir to a back-pressure chamber via a constriction device, and which further comprises an oil channel, which takes lubricating oil from the back-pressure chamber to working chambers formed between the two spiral elements, and which does so via at least one fine continuous bore passing through the thickness of the end plate of the orbital spiral element on the inside of the spiral wall section within the range of 1/2, and specifically at magnitudes of the spiral wall coil number ratio, under which the ratio of the number of coils calculated from the outer ...

Title: Method and apparatus for welding the longitudinal edge of a can shell
Inventor: BERSCH BERNHARD DR
IPC: B23K26/24
Filed: 1984-02-29
Abstract: The invention discloses the use of the known process of laser beam welding for the mass production of shells to be welded of metal cans. The high requirements made of the accuracy of the weld are met by virtue of an accurate feed system for the welding machine comprising an X rail, a guide bar and resiliently mounted jaws of a caterpillar train. Any remaining inaccuracies are rendered innocuous by the fact that welding is carried out from both sides of the can shell and that less than the total thickness of the sheet is joined together by each weld. <IMAGE>

Title: Three-layered house chimney
Inventor: AUGUSTIN LOTHAR
IPC: E04F17/02
Filed: 1984-03-06
Abstract: In the case of three-layered house chimneys which are formed from shaped casing pieces in which an inner pipe is inserted, problems may be expected if the inner pipe is not sufficiently insulated from the shaped casing pieces. Up until now, insulating mats have been pushed in in order to provide an insulation between the inner pipe and the shaped casing pieces. The insulating mats can no longer fulfil their purpose, however, if they become moist, which is always the case, in particular at low chimney temperatures, and are destroyed by the resulting sulphuric acid or sulphurous acid. To remedy this, it has also already been proposed to arrange the insulating mats at a distance from the outer wall of the inner pipe, so that ducts running along the inner pipe are produced, and to bring these ducts into connection with the outside air, by way of openings in the lower chimney region and an upper-side opening, in order thus to achieve a constant air movement which is guided upwards when the chimney is operating and which reliably keeps moisture away from the insulating mats. <IMAGE>

Abstract: Pyridin-2-acetonitrile is prepared by allowing cyanogen chloride to act on 2-methylpyridine in the gas phase. The pure pyridin-2-acetonitrile is obtained from the resulting gaseous reaction product by quenching the reaction product with a liquid, neutralisation and distillation, where liquid reaction product is used for the quenching step and ammonia is used for the neutralisation step. The pure pyridin-2-acetonitrile is obtained in high yields. Virtually all of the unreacted 2-methylpyridine is recovered at the same time.
