Patent DE-3146439-A1 (DE)
Title: Two-stroke engine with valve timing which varies as a function of the speed
Inventor: TOPITSCH ALEXANDER
IPC: F02B25/00
Filed: 1981-11-24
Abstract: The invention relates to a port-controlled two-stroke engine with valve timing which varies as a function of the engine speed. In two-stroke engines of known type the position of the control ports and the valve timings are constant over the entire speed range and represent a compromise between the demands on the individual speed ranges. The subject of the present invention is an arrangement which permits the speed-related adjustment of the valve timings to the particular demands. This is achieved by a speed-related, axial displacement of the cylinder (13) and hence of the control ports (20, 42) in relation to the piston dead centres by the amount (X, Y). The cylinder head (30, 30'), carried by support elements (29), rests independently of the cylinder (13) on the crank casing (12) and ensures a constant compression ratio over the entire adjustment range. The piston-shaped section (30') of the cylinder head (30) is immersed in the cylinder bore (13') and provides for sealing of the combustion chamber. The sealing off of the cylinder (13) from the crank casing (12) is achieved by profiled elements (21') positively interlocking with one another. By means of this arrangement an improved power output is obtained. <IMAGE>

Patent DE-3202721-A1 (DE)
Title: Proportional pressure valve for hydropneumatic vibration dampers, in particular a bottom valve which can be installed in twin-tube dampers
Inventor: ADRIAN ADOLF
IPC: F16F9/348
Filed: 1982-01-28
Abstract: Proportional pressure valves for hydropneumatic vibration dampers, in particular for twin-tube dampers with bottom valves (8) installed between their inner and outer cylinder (3 and 4 respectively), are provided with pressure-stage passages (16, 17, 18) which are covered by one or more valve spring discs (21) and through which damping fluid flows during the particular pressure stage of the damper. Especially in the case of twin-tube dampers, these proportional pressure or bottom valves must offer a sufficient flow resistance to the displacement of the damping fluid towards the pressure-gas space which occurs during their respective compression movement. In order, in the event of large, in particular very rapid, compression movements of the damper, i.e. when large compression shocks occur, to reduce the effect of the latter or protect the vehicle occupants from them, the pressure-stage passages (16 to 18) have effective cross-sections of different sizes and are arranged on different sides of the clamping centre (19) of the valve spring discs (21). Provided behind the latter at a short distance is a stop disc (23), against which comes to rest the side of the valve spring discs (21) which faces from the pressure-stage passage (18) with the larger effective cross-section and initially bends purely cylindrically with increasing pressure build-up. Only in the event of a larger pressure build-up does the other side of the valve spring disc lift off from the outlet opening of the pressure-stage passage (16) of smaller effective cross-section. <IMAGE>

Title: Vortex chamber filter for removing solids from a gas stream
IPC: B04C3/06
Filed: 1982-02-03
Abstract: The invention relates to a multistage vortex chamber filter for removing solids from a gas stream. The filter is provided with a plurality of separate multistage filter elements in each of which at least one flow channel is provided to which a plurality of vortex chambers is connected. The cross-sectional area of the flow channel decreases from chamber to chamber in the direction of flow in order to ensure a constant flow velocity. The inlet and the outlet of the flow channel are formed in opposite end walls of the filter elements. In a filter housing, there is arranged a plurality of filter elements, each between two parallel walls at a distance from each other, for the opposite inlet/outlets of which filter elements, through-holes are provided in the walls. The filter housing in this case is furnished between the walls with at least one clean gas outlet orifice. The inlets and outlets of the filter elements in front of the walls are each connected to a clean gas inlet or a residual gas outlet. <IMAGE>
Patent DE-3203727-A1 (DE)
Title: Sharpening device
Inventor: KOLLER WALTER
IPC: B43L23/00
Filed: 1982-02-04
Abstract: Closable sharpening device for sharpening pencil and compass points, having a sharpening and stripping surfaces for the points and a displaceable protective sleeve. Closable sharpening devices of this type are used in order to be able to sharpen, for example, compass points at any desired angle and protect the user from being soiled by the abraded dust. The technical problem with sharpening devices having protection against abraded dust is to catch the abraded dust produced reliably with free accessibility and visibility of the sharpening surface and, when the device is closed, to be able to transport it in a leakage-free manner and also to prevent the dust being scattered on opening. This invention solves the said problem in that an inclined sharpening surface (1) is arranged in a container (2) which is open at the top and whose edge (3) is surrounded by a resilient seal (4), consisting e.g. of a plush material, which, when the sharpening device is closed, acts against the lid surface (5) of the protective sleeve (6) and thus closes the container (2) in a dustproof manner and, on opening, also scrapes back into the container any abraded dust adhering to the lid surface (5). Because of the dustproof closability, this sharpening device is especially suitable, for example, for pupils or students who are required to use an all-purpose point-sharpening device at varying locations. No cleaner method of sharpening compass points quickly is known. <IMAGE>

Title: Device for controlling a signal box
Inventor: HOMEISTER MANFRED DIPL ING
IPC: B61L21/00
Filed: 1982-10-20
Abstract: In the control of signal boxes (Stw) via operator stations (B1 to Bm) provision is made for specific commands (FB) to be separately enabled by the respective operator before they are issued to the key relays (G1 to G36) of the signal box. In order to ensure this, the key relays which are involved cannot be connected directly but rather only via series relays (GT1 to GT36). These series relays are a component of a test and logical connection circuit designed using relay technology. In said circuit, on the one hand the command entered is tested for plausibility and on the other hand dependency is provided between the operator station (e.g. B1) from which the operating action requiring enabling was performed and the enabling switching means (KF1) of this operator station. The testing and logical connection circuit is provided in common for all the operator stations. It ensures that no command which bypasses the signal box safety system can be effected without the involvement of an operator.   <IMAGE>
