Title: Automatic or manual transmission switching device for vehicle - has selection lever moved into manual position for selective manual operation of gears
Inventor: MAIER ULRICH
IPC: B60K20/02
Filed: 1990-02-22
Abstract: The switching device uses a selection lever (5) allowing different gear ratios to be selected, displaced within a switching box (6) between at least one automatic position (D) and a manual position (M).

Patent DE-4009082-A1 (DE)
Inventor: BOGUSLAWSKI ZBIGNIEW
IPC: C02F1/28
Filed: 1990-03-21
Abstract: Process for removing impurities in the form of ammonium compounds and ammonium compounds combined with phosphates and possibly heavy metals, from industrial, agricultural or private waste water. In a first stage, the waste water is passed through heaped pellets consisting essentially of hydrogen phosphate salts with a cation from the second main and sub groups of the periodic system (MeHPO4) and/or in a (second) stage, the waste water is passed through heaped pellets consisting essentially of a phosphate salt with a cation from the second main and sub groups of the periodic system (Me3(PO4)2). The second stage can be omitted if the waste water contains only ammonium impurities. To manufacture the pellets required for the process, phosphoric acid and a metallic oxide are mixed and reacted at a constant working temperature between 25 and 30  DEG C and the sludge containing the orthophosphate or hydrogen phosphate, to which metallic oxide and kaolin are added as a binder, is pelletized. The green pellets are air dried and subjected to a heat treatment, preferably at approximately 300  DEG C. The heating to the activation temperature and the cooling following the activation are carried out at a heating and cooling rate, respectively, of 50  DEG C/hour.

Title: Torsion free safety clutch with displaceable pretensioned balls - has fixed indentations and recesses with freedom of play produced by widening space between clutch halves
Inventor: RIMPEL ANDREAS
IPC: F16D7/06
Filed: 1991-06-19
Abstract: The balls or other entrainment bodies are mounted at intervals along a coaxial circular track displaceable in recesses in one of the clutch bodies. The recesses (1) of the driving clutch body (2) and the disengaging indentations (6) in the driven clutch body (5) are formed exactly on a centre axis (7) at an angle to the centre axis (8) of the clutch. By moving the driving and driven clutch bodies axially (9) there is a stagger (11) between the active lines of the balls (3) and detent indentations which changes proportional with the distance. The distance between the pairs of indentations does not change but rather the distance between the balls since these are mounted in the recesses at an angle to the clutch centre axis and can thus only move axially at this angle. ADVANTAGE - Simplified mfg. process wherein the clutch is self-adjusting in the event of wear.
