Patent DE-4237194-A1 (DE)
Inventor: DENZ HELMUT DIPL ING
IPC: G01P15/16
Filed: 1992-11-04
Abstract: The invention pertains to a device for determining the rotational speed gradient dn/dt of a shaft of an internal combustion engine, where the rotational speed gradient dn/dt is determined in the control unit as a function of the cube of the engine speed and the difference of two segment times, the speed gradient being determined only in time-uncritical phases, whereas in the time-critical phases only segment times are read or stored so that in these time-critical phases the data required for the control of the internal combustion engine can be computed independently of the engine speed determination.

Patent DE-4311161-A1 (DE)
Inventor: BINDER ALFRED
IPC: B23D51/10
Filed: 1993-04-05
Abstract: Quick-clamping device for jigsaw blades, with a receptacle in the plunger (1) of the jigsaw as well as holding means which reach behind lateral projections (4a) on the jigsaw blade (4) and thereby secure the jigsaw blade (4) at the bottom to prevent it from falling out, characterized in that a rotary sleeve (5) preloaded rotatably in the peripheral direction is mounted on the plunger (1). Inner surfaces of the rotary sleeve (5) form control paths (5a) for the holding means, designed as radially movable locking elements (7), for the saw blade (4). Sitting on the plunger (1) is a sleeve-shaped ball carrier (8) which mounts the locking elements (7), designed as retaining balls, in radial passage openings and rotatably accommodates the rotary sleeve (5) to the outside. The rotary sleeve (5) is preloaded in the second angular position by a torsion spring (6) mounted between it and the ball carrier (8) in an intermediate space. The control paths (5a) in the inner wall of the rotary sleeve are formed in such a way that the angle of the control paths, with increasing positional displacement of the retaining balls to the inside, runs flatly in such a way that, supplemented by the restoring action of the torsion spring (6) acting on the rotary sleeve (5), at least self-locking or ever-increasing infeed of the retaining balls comes into effect. <IMAGE>
Patent DE-4312492-A1 (DE)
Title: Slide valve control for four-stroke engines and delivery pumps in cone slide valve form
Inventor: BARTOS STANISLAV FRANZ
IPC: F02B75/02
Filed: 1993-04-16
Abstract: The idea of replacing the disc valve by a slide valve is as old as the internal combustion engine itself. The history of the engine has pages full of valve engines, and slide valve controls have of late gone into the background or have been entirely forgotten. There is a common reason for all this, namely a rapid wearing of sealing faces as a result of combustion residues and consequent leaking of the slide valve. It is precisely this disadvantage which I intend to overcome by rotatable sealing elements and cone slide valves and to bring out the disputed advantages of slide valve control. Simplified engine construction, improved utilisation of fuel because fewer parts are needed and no valve springs have to be depressed. The engine will have quieter and smoother running thanks to the absence of valve discs, which forcibly interrupt the flows of medium and strike into the valve seats. The possibility exists therefore of making the cylinder head and the housing in one, because no seating rings and valves have to be machined and fitted and as a result no cylinder head gasket is needed. An engine of this design can burn various fuels as required, for example all grades of petrol, diesel or gas, even with a low octane rating. The slide valve control in cone slide valve embodiment may be regarded as a contribution to environmental protection in which improved utilisation of energy expels fewer wastes into the air.

Patent DE-4337065-A1 (DE)
Title: Axial piston machine in swash-plate type of construction
Inventor: DEININGER HORST DIPL ING
IPC: F01B3/00
Filed: 1993-10-29
Abstract: With the present invention, an axial piston machine of constant delivery and absorption volume with an adjustable swash plate (11) is presented which is comparable in its overall size with a constant axial piston machine. The reduction in the overall size compared with conventional axial piston machines adjustable in operation and having a pivotable swash plate (11) can be attributed to the fact that the centre of the radius of curvature of the rear side of the swash plate is arranged at a considerable distance from the swivel centre (13) of the drive mechanism. A further special feature of the axial piston machine according to the invention lies in the fact that the swash plate can be adjusted by two stud bolts (15, 16) from outside the housing (1). <IMAGE>
