Patent DE-3842963-A1 (DE)
Title: Workbench for powered hand tools
Inventor: SPAETH RUDOLF
IPC: B25H1/00
Filed: 1988-12-21
Abstract: A workbench for powered hand tools is proposed, having a frame formed from profiled strips and a raisable slab held on the frame, which slab in the operating position rests on the frame and covers the respectively inserted powered hand tool, the working tool of which projects upwards through an opening in the slab, and on the upper side forms a workpiece-supporting surface. Arranged on the frame is a receptacle which extends within the clearance bounded by the frame and is in the form of two opposite slides which contain indentations, into which the powered hand tool to be inserted in each case can be inserted from above by way of parts provided on the tool side which fit into the indentations. The slab is pivotably mounted on the table edge, so that it can be lifted up for these replacement purposes and thereafter lowered again so as to cover the inserted powered hand tool.

Title: Device for the step-by-step feeding of a saw blade on a saw-blade cutting machine
Inventor: ISELI BENNO
IPC: B23D63/00
Filed: 1989-01-12
Abstract: Provided on a revolving crank (3) is a crankpin (31) which acts on a pin track (42) of a rocking lever (4) only during part of its time of revolution. During this time, the rocking lever (4) is swung forward and a catch (5) is thereby advanced (via a joint (48)). The nose (50) of this catch acts on a tooth (70) of the saw blade (7) to be fed, as a result of which the saw blade (7) is fed one step. The crankpin (31) then leaves the pin track (42), and a restoring spring (36) swings the rocking lever (4) rapidly back into its rest position (Fig. 1). The catch (5) is thereby also pulled back rapidly into its rest position. The next movement of the catch (5) only takes place when the crankpin (31) acts again on the pin track (42). The time remaining for the machining of the saw (7) during the feed pauses is consequently greater than in known crank drives. It is possible to increase the number of revolutions of the crank and thus the production rate of the cutting machine. <IMAGE>

An electro-acoustic transducer is provided on the surface (24) at the incidence end, with which acoustic surface waves, collinear to the waveguide, can be generated in the lateral interface (22). The laser radiation (82) impinging on the incidence end is polarised in the ordinary (75) or extraordinary (73) polarisation direction (61), the light detector being sensitive for the laser ray (73 or 75) rotated by 90 degrees in its polarisation direction. USE/ADVANTAGE - The sensor gives very accurate results for the absolute refractive index of the gas.

Title: Monitor circuit for oil pressure switch on IC engine - has electronic switch in series with capacitor supply for time delay protection
Inventor: STEIDLE SIEGFRIED
IPC: F01M1/20
Filed: 1990-06-22
Abstract: The engine is protected by an oil pressure switch (12) which shorts the ignition coil if there is insufficient oil pressure for engine running. The oil pressure switch is in series with an electronic switch (14) powered by a capacitor charged from the l.v. pulses from the coil. The charging action of the capacitor, when the engine is first started, provides a time delay in oil pressure monitoring, giving time to build up the pressure. The capacitor holds its charge for a set time after switch-off to enable the protection circuit to short the coil is there is a fault in the protection system. This prevents restarting immediately. USE/ADVANTAGE - Fail-safe protection for engine. Any i.c. engine, e.g. powering chain-saw.

Abstract: The invention relates to a profiled vehicle tyre with grooves in the tread which run obliquely with respect to the running direction when viewed from above and whose edges are inclined by an angle in relation to the radials, the distance of the grooves from one another in the running direction being modulated in accordance with a profile sequence which disperses the excitation frequency so that profile positives of differing extent are produced between the grooves in the circumferential direction, the extent of the grooves in the running direction also being modulated in accordance with the profile sequence for the distance of the grooves. 
<??>In order to reduce a change in the frequency dispersal brought about by a profile sequence when friction occurs and in order to reduce non-uniformities in the transmissibility of longitudinal forces and transverse forces, it is proposed according to the invention that the tangent of the angle also be modulated in accordance with the profile sequence for the distance and the extent of the grooves.

Abstract: In pressure electrolysis plants, water is decomposed into hydrogen and oxygen. During this process, the electrolysis cell block is in a pressure-resistant encapsulation and has an electrically nonconductive fluid kept at the working pressure of the pressure electrolysis flowing round it. The conductive fluids used are feed-water and hydrogen. The pressure of the fluid is controlled by means of the pressure of one or both product gases, for example the pressure in the hydrogen separator. The fluid inside the encapsulation can be heated to establish the starting temperature of the process, while cooling is carried out during stationary operation by indirect heat exchange in the encapsulation.
