Title: Camshaft angular positioner for four-stroke IC engine - has magnetic valve for selective control of hydraulic lines supplying fluid to motors setting additional cams
Inventor: RUOFF MANFRED DIPL ING
IPC: F02B75/02
Filed: 1991-05-17
Abstract: Three additional cams (1.1, 1.2, 1.3) axially offset between bearings of the camshaft are adjusted by the pistons (4-6) of respective motors to which fluid is supplied via hydraulic lines (2.6, 2.7, 2.17) with non-return valves (11, 12, 18).

Title: Prodn. of construction component for building - using shaft and pouring plastic via transverse drillings into end recess, and moulding on emergence
Inventor: WERNER KLAUS
IPC: B29C70/76
Filed: 1991-06-13
Abstract: Constructional components, partic. for buildings, are produced by forming a recess in the end of a shank. One or more transverse drillings from the outside surface of the shank lead into the recess. Plastic is poured in through them and moulded after it emerges from the recess, a mould being typically fitted onto the shank end. Alternatively, the plastic can be arranged to flow into a second shank, joining the two together. Reinforcing material such as glass-, or carbon-fibre can be mixed in with the plastic, also fibreproofing powder, while the shank can be of wood. ADVANTAGE - Simple to produce and easy joining of components.

Title: Optimal control of cylindrical grinding of non-cylindrical surface - by initial workpiece contour check using grinding wheel to enable electronic evaluation of zigzag feed path
Inventor: TRACHSEL KONRAD
IPC: B24B5/04
Filed: 1992-07-28
Abstract: The method of controlling the successive cutting passes of a grinding wheel (14) during the cylindrical surface-grinding (13) of a previously turned workpiece (10) comprises a step of checking the unground workpiece to determine its non-cylindrical contour i.e. conical (13), convex (16), concave (18) etc. by traversing the wheel (14) to touch its ends and centre. Contact noise or increased motor current is sensed and the resultant signals transmitted to a program controlled evaluation unit. The unit determines the necessary cutting sequence starting with the largest diameter and defines the longitudinal and cross-traverses to generate an optimal zig-zag path for material removal. USE/ADVANTAGE - Eliminates unproductive time when wheel is not in contact with workpiece due to surface irregularity. Assesses feasibility of zig-zag programme resulting from initial check e.g. inaccuracies of less than 0.01 mm would not need to call-up zig-zag procedure. Eliminates the non-cutting longitudinal travel and reduces the processing time.
