Title: Rotating cylinder lock with double locking feature - has axially and radially moving pins actuated by key pushing contact faces for release
Inventor: PERKUT BRANKO R
IPC: E05B47/00
Filed: 1978-06-28

Title: Clay roofing tile prodn. by pressing in mould - wetted with granite and water suspension before each charge
Inventor: GATZKE HORST DR ING
IPC: B28B13/06
Filed: 1978-08-22
Abstract: In clay roofing-tile prodn. by pressing in moulds, esp. steel moulds, subjected to an electric shock with D.C. tension to release the pressed tiles, the mould-nests are coated, esp. by spraying, with a suspension of graphite and water before each clay blank charge. The addn. of alcohol to the graphite-water suspension increases suspension volatility and reduces the drying time of the tiles. Treatment reduces electric shock damage to mould nest surface and increases mould service-life, e.g. by 50%, i.e. to 6 months.

Title: Waste water pumping system - draws water from bottom of vessel and uses flow to assist raising water to top of vessel
Inventor: LIEBGOTT HELMUT
IPC: F04B43/06
Filed: 1978-12-16
Abstract: The arrangement is intended for moving liquid particularly waste water up into a vessel (6) while at the same time drawing liquid (13) from the bottom of this vessel. The two liquid flows pass through chambers (9, 11) which are separated by a diaphragm (12) while the flows through the chambers are controlled by valves (8, 10, 14, 15). The static pressure of the flow from the vessel in the chamber (11) displaces water from the chamber (9) thus assisting the flow to the top of the vessel. The valves may be non-return valves. The final lift to the top of the vessel may be by a small auxiliary pump (5).

Title: Integrated circuit FET with additional gate - held at constant potential by integral divider on integrated circuit chip for screening purposes
Inventor: SCHUERMANN JOSEF
IPC: H01L29/78
Filed: 1978-12-22
Abstract: A f. e. t. has an additional gate electrode, held at a constant potential, and designed to reduce interference by acting as a screen and reducing gate/drain capacitance. Between the control gate electrode (7) and the drain (6) is a second gate (9) held at a constant potential by positioning, and conductivity of, on the channel zone (14) underneath it. The position of the gate (9) on the substrate (8) makes it a potential divider between the source (5) and drain (6), which both determines the constant potential of the second gate (9) and effectively makes the unit a two f. e. t. configuration. An alternative is offered whereby the two f. e. t. configuration is replaced by a f. e. t. diode chain arrangement. The f. e. t. is designed for mixer and h. f. applications.

Title: Permanent wave curler - positioned by sheathed wire nipped in groove or hole-and-pin straps
Inventor: WAKARIAN ALEXANDER
IPC: A45D2/12
Filed: 1979-03-27
Abstract: Permanent wave curlers in the shape of cylinders with a concave surface, pref. made as a plastic injection moulding, have at their ends annular grooves. A long wire inside a plastic sheat can be squeezed into this groove to keep the curlers at the right distance from each other and close to the head. This groove and wire can be replaced by a spiral or by radial holes in the end of one curler alternating with radial pins in the next, which are engaged in a plastic strip with alternate holes and pins. Such curlers exert no pressure which may lead to hairs breaking off when chemicals are applied; they prevent the untwisting of the rolls of hair.

Title: Wall insulating material discharge tool - has slotted or funnel shaped discharge outlet for granular substance, between two jets for binder
Inventor: FRAGER JOSEF
IPC: E04F21/12
Filed: 1979-07-28
Abstract: The device for applying a finishing layer to a wall consists of a pistol shaped tool with a handgrip and with two supply lines for two ingredients. One line terminates in an oval or slot shaped discharged opening and the other line terminates in two jets, one each side of the slot, so that the two ingredients are mixed as they are discharged. Pref., the slot has a figure of eight section, elongated vertically, and the jet holes are above and below, on its centre line.. The device is used for applying granular polystyrene and an epoxy resin so as to form an insulating layer. The feed and discharge systems ensure that mixing of the ingredients does not occur until discharge, so that supply tubes do not become clogged by solidifying material.

Title: Appts. for filling foam moulds - comprising stationary mixing head and driven turntable supporting moulds
Inventor: OPPL OTHMAR JOSEF
IPC: B29B7/00
Filed: 1979-12-19
Abstract: Appts is for running liq foam into moulds. It has at least one mixing head, a turntable and moulds placed on the turntable. The mixing head is stationary. The turntable has a driving unit which is designed so that during filling of moulds the turntable speed is greatly reduced, but between filling times the speed is stepped up.
