Title: Automatic cleaning system for WC bowl - with brush carrying spray nozzles actuated each time bowl is flushed
Inventor: BOROWSKY HANS-DIETER
IPC: E03D9/06
Filed: 1989-09-27
Abstract: A WC is fitted with a cistern (Z) to flush the WC bowl (12). The WC bowl is fitted with a brush (11) near its upper edge.

Title: Decontamination of limited area of ground newly contaminated - with oil, etc., by forming concrete barrier below contamination and flushing with oil-absorbent fluid
Inventor: SCHUETTE REINER DR
IPC: E21B43/40
Filed: 1989-11-07
Abstract: This is a decontamination method for an area of ground that has been newly and locally contaminated with liquid hydrocarbons or hydrocarbon mixts. A washing fluid is fed into the ground, and on its way down it absorbs the harmful substances. Below, it is drawn off via at least one suction pit, conveyed to the surface, cleared of the harmful material, and if necessary, fed again into the ground. Before the washing fluid is used, concrete emulsion is sprayed in under pressure to form a trough-like barrier from whose deepest part the washing fluid is sucked out.  Several variants are claimed. USE/ADVANTAGE - The method, for dealing with these hydrocarbons as soon as possible after the contamination, is quick and not very expensive; it limits the extent of the affected area, so helping to reduce costs. It can be used below buildings, roads, etc. ground water is not affected.
Patent DE-3937735-A1 (DE)
Inventor: POWELL PETER HUBERT
IPC: B61H13/02
Filed: 1989-11-13
Abstract: A railway braking system including a hand-brake system and a service brake system, in which the hand-brake system is interlocked with the service brake system such that when the hand-brake system is applied the service brake system is rendered incapable of full brake release and is rendered incapable of being re-charged until the hand-brake system has been released. When the hand-brake is operated a mechanical interlock operates valve 12 so that pressure in auxiliary reservoir 3 can pass to and open valves 19 and 21. Valve 21 vents brake pipe 1 to atmosphere and valve 19 vents to atmosphere via a blow-down safety valve 26. Thus valve 21 prevents the service brake system along a train of vehicles from being recharged, and valve 19 prevents the service brake 4 from being fully released. <IMAGE>
