Patent DE-2454548-A1 (DE)
Title: Composite paving comprising flagstones and spacers, esp for terrasses - has a base of rubber granules mixed with isocyanate and polyurethane foam treading top layer
Inventor: MAUCH KARL
IPC: E04D11/00
Filed: 1974-11-18
Abstract: A paving made of flagstones and spacers, esp. for the surfacing of terraces, comprises slabs with a corrugated (esp. with trapezium-shaped cross-section) profile on their undersides, obtd. by press-moulding at 60 degrees C for 10 mins., using a mould which also imparts to the mouldings groove along their edges and openings, near the corners, adapted to receive adapter sleeves. The slabs are made of a rubber granulate mixed with an isocyanate to which a satd. aq. MgCl2-soln. has been added to give a pasty consistency. The slabs are built up of a base body onto which a treading surface has been applied in closed frame, comprising an integral foam obtd. from an isocyanate and a polyol. In the grooves there are double springs fitted located between the slabs, having a spacer and threaded bushings, are fitted into the openings. The latter have threaded bolts screwed into them which bear on setting blocks. Te slabs as claimed can be securely laid without risk of disclocation in use. The profiled underside enables them to be laid on relatively loose bases e.g., corase grit, or gravel. They may be made in dimensions of ca. 40-80 cm. square and 3-4 cm. thick. The foam treading surface renders them pleasant to walk on whilst imparting good weather resistance. They have good noise-damping characteristics. Accurate laying is relatively simple as the threaded bolts allow precise adjusting for levelling, at all four corners. The double spring acts as spacer.

Title: Hydraulic drive for tractor-drawn rotary plough - without spring-loaded return mechanism for piston rod
Inventor: SCHULTE HEINZ ING GRAD
IPC: A01B3/421
Filed: 1975-04-12
Abstract: A hydraulic drive for a tractor-drawn rotary plough has a double-acting fluid cylinder (10) between the pivotable plough frame (2) and the plough forecarriage and which is driven by a simple conventional control mechanism of the tractor hydraulics in conjunction with a reverse switching valve (23, 24) and a non-return valve (32). The coupling of the fluid cylinder allows movement of the piston rod (11) without dead centre positions and hydraulic end position locking of the plough frame. The switching valve can reverse at the end or before the beginning of rotation, and the pulse for actuating it occurs independently of rotation. The non-return valve may be double-acting and hydraulically released, and operates without oil leakage.

Title: Machine tool pneumatic tool setter - retracts tool to eliminate return traverse tooling
Inventor: GERK WILFRIED
IPC: B23Q15/04
Filed: 1975-04-16
Abstract: A machine tool has a pneumatic setter (5) which adjusts (8) a tool holder (6) to the work piece (W).

Title: Electronic HV ignition system for IC engines - has saw tooth generator and uses comparator system to produce trip in signal
Inventor: DOEMLAND CHRISTOPH ING GRAD
IPC: F02P3/045
Filed: 1975-06-21
Abstract: The circuit has a sawtooth generator (3) and a transistor (16) which are used to synchronise the impulse edge and register (4) for a differential voltage gained from the respective peak values of the generator voltage and a voltage corresponding to the tripping time. The tripping signals are produced by a comparator (5) to which the differential voltage and the sawtooth voltage is fed. The current fed to the primary coil for each ignition impulse is of the same duration independent of engine rpm in order that the coil does not become overheated and use up unnecessary battery voltage particularly at slow speed, due to energisation for an unnecessarily long period of time.
