Title: Shut=off device for combustible fluid piping - includes expandable insert for emergency sealing
Inventor: ALMERT ADAM
IPC: A62C2/04
Filed: 1991-02-09
Abstract: A shut-off device, for combustible fluid transport piping, consists of a housing with an inlet and an outlet, between which a shut-off member, mounted on an actuator, can be moved between an open and a closed position, one or more seals of material with limited heat resistance being provided between the shut-off member and the housing. The novelty is that an insert (16), of material which expands irreverisbly at high temp., is associated with the seal (21) so that, when the seal is destroyed at high temp., the insert expansion causes displacement of the shut-off member (5), which is loosely mounted on the actuator (9), into an emergency sealing position. Pref. the insert (16) consists of glassfibre-reinforced, epoxy resin-bonded alkalimetal (esp. sodium) silicate. USE/ADVANTAGE - The shut-off device may be a ball valve for gas piping. It provides safe emergency sealing when a fire occurs.

IPC: H01L31/119
Filed: 1991-06-20
Abstract: A position-sensitive semiconductor detector has a fully depleted base region having a first conductivity and insulating layers on both main surfaces as well as conductive electrodes on these insulating layers (MIS structure). The detector is characterized by the following features: a) the regions of first and second conductivity on the two main surfaces which are required for depleting the base region of first conductivity are produced by forming inversion and accumulation layers in the surface region below the MIS contacts, at which the influenced signal charge is taken off simultaneously; b) the regions of first and second conductivity on the two main surfaces which are required for depleting the base region of first conductivity are completely surrounded by regions of opposite conductivity formed by accumulation and inversion of charge carriers and whose conductivity is controlled by MIS contacts; c) the external voltage is supplied to the regions of first and second conductivity from regions of first and second conductivity both of which are located preferably near one of the two main surfaces. In addition, the detector structure can be produced in three masking steps.

Title: Program-controlled washing machine with laundry drum - features automatic controlling water supply from difference between drum speeding-up and slowing-down times
Inventor: STAMMINGER RAINER DIPL PHYS DR
IPC: D06F34/18
Filed: 1992-02-12
Abstract: A program-controlled washing machine features a laundry drum rotating in a washing soln. container.

Title: Goods transport system along processing track - returns suspension beams from auxiliary track onto main one at points from which they were previously extracted.
Inventor: PAULS HELMUT
IPC: B65G37/02
Filed: 1992-09-04
Abstract: The goods are loaded onto suspension beams round a main track (2), from which selected beams are transferred at a first point to an auxiliary track (3).
