Patent DE-4410156-A1 (DE)
Title: Control system for variable output pump
Inventor: WIBBERG BERNHARD
IPC: F04B49/08
Filed: 1994-03-24
Abstract: The pump output is governed by means of an electrical control system which compares a signal from an output pressure sensor to a reference value and controls a pair of proportional valves accordingly. The proportional valves (15,16) supply hydraulic pressure for two different functions, such as a motor drive (13) and a cylinder (14), from the pump (10). Electro-magnets (19,20,21,22), controlled from the control system (25), set the valve slide positions each way from their centre positions. A change-over valve (26) is operated by load demand from the two users (13,14) and controls the valve (30) which, in turn, causes the pump (10) to supply the maximum pressure required. A pressure sensor (35) feeds back a signal to the control system to ensure adequate pump pressure for the demand.

Title: Method and device for producing mixtures from aggregates of stone masses or ceramic masses
Inventor: TONCELLI DARIO
IPC: B01F13/00
Filed: 1994-05-10
Abstract: A method and a device are described here, for the homogenisation of mixtures made from aggregates of stone masses or ceramic masses for their subsequent moulding to form panels or blocks. Various starting masses are produced, which differ from one another in the type of the aggregate and/or the colouring thereof. The starting masses are supplied into different areas and fed in layers onto arrangements for carrying and conveying the layered mass thus produced, which have a conveyor belt 14 which can be moved along an essentially curved path, and in which, when the mass arrives in the end area of the conveyor belt 14, the mass is then, under the action of gravity, made to fall, through guide arrangements 22, onto the starting area at the end of at least one second conveyor belt which can likewise be moved along a curved path. When the layered mass arrives in an area corresponding to the end section at the end of the second conveyor belt, the mass is made to fall, under the action of gravity, in the said manner onto the starting area, lying underneath, at the end. The first and second conveyor belts are stopped after the expiry of a predetermined time while their direction of movement is simultaneously reversed in order to [lacuna] the layered homogenised mass out of the starting area at the end for supply to a moulding station to be formed into panels or blocks made of stone or ceramic material ...

Patent DE-4426250-A1 (DE)
Title: WC cistern handle action
IPC: E03D5/02
Filed: 1994-07-25
Abstract: The frame (20) is joined to the wall etc. through a flexible element (22,23) so as to prevent any direct connection between them. The element is grooved or recessed to take the frame and is recessed to the side at intervals to allow for diverse curvature, possibly using a plate cutout as element to adapt to the frame contours. Thus the flexible material between the stop faces of the frame and operating element (15) prevents any direct contact between these stop faces. The flexible material can be natural or synthetic rubber, plastics foam, cork, coconut and/or metal springs, and the operating element has two spaced stop faces (19) at right angles to the operating element and spaced by an interposed stop element (21) which also has two stop faces and is joined to the frame element. Each stop face can be allocated an O-ring.

Patent DE-4429744-A1 (DE)
Title: Safety trocar for use by surgeons
Inventor: STORZ MARTIN
IPC: A61B17/34
Filed: 1994-08-22
Abstract: The trocar cutter bit (28) can slide in a sleeve (12). An extension of the cutter bit has a recess with square edges with which a spring-loaded locking pin (34) can be pushed into engagement, when the cutter is pushed out. The axial force of the cutter during cutting acts against the side of the pin and keeps it in position. When there is no axial force on the cutter bit, e.g. when the cutter has passed through the abdominal wall, there will be no retaining force on the pin which will be pushed out by its spring. A spring (30) which acts on the extension of the cutter will pull the cutter back into the sleeve (12).

Patent DE-4439496-A1 (DE)
Title: Clothing waist expansion system
Inventor: SCHMIDT FRIEDRICH-ERNST
IPC: A47G25/06
Filed: 1994-10-25
Abstract: Expansion or stretching are performed mechanically, using a stretching lever (6) assisted by waist centre and end holders. The design centres around an evenly perforated segmental telescopic tube for use in the horizontal to any required expansion. Thus the waist as joined to the clothing, is clamped for this purpose in the centre and then holders and lever are used to stretch the material in stages to expansion limit at which point the waist is held by waist holders. The tube telescopes away either side off its centre tube via screwing end connections, using the perforations along the tube to set the required waist measurement. The end holders (4) are set at the centre tube (2) end holes (7), using the pins (10) to anchor the selected waist setting. Thus tube (5) is telescoped out off the tube with the help of the lever, so forcing the waist centre away evenly to both sides from the held ends of the waistline. The lever is typically bevelled at the end for easy hole entry.
