Title: Integrated bracket for mains-independent elongated light fitting - provides full fitting length with pivotal point at centre of gravity for greater stability and position latching
Inventor: GLUECK DIETER
IPC: F21V21/14
Filed: 1979-05-17
Abstract: The light fitting provides a positioning facility due to its integrated bracket, and utilises the principles used in bifilar vehicle lamps for dipped and long distance light beams. The bracket is integrated into the light fitting, following the section between the spotlight head and the rest of the elongated light fitting. The brackets pivoted point is located at the fittings point of gravity, which provides for stability and secure light fitting position latching. In its folded position the bracket protects the spotlight head. In a suitable design it forms a roller brake. The bracket enables movement of the light fitting through 360 deg., with any defined position locking. Additional arrangement may provide selection of dipped or long beam (spotlight) modes.

Title: Rectifier cascade with AC slip ring motor - has control sets coupled to auxiliary coil of rectifier transformer, delivering synchronising voltage
Inventor: WALTSCHEW ANTON DIPL ING
IPC: H01F27/38
Filed: 1979-07-12
Abstract: Pref. an auxiliary voltage, derived by converters from a transformer overvoltage, is used for synchronising the control sets of current rectifiers, coupled to high voltage mains via rectifying transformers. The overvoltage coil of the rectifier transformer is in parallel to the stator coil of the slipring a.c. motor. The control sets (7) of the cascade (4) are connected to an auxiliary coil (13-15), additionally arranged on the core of the transformer (5) and delivering the synchronising voltage. In order to protect the synchronising voltage delivering auxiliary coil in case of the transformer being short circuited, a protecting device is mounted on the transformer cover, or directly near its bushings. In this manner the converters of the conventional systems become superfluous.
Patent DE-2930645-A1 (DE)
Title: Fixing ceramic filter compsn. porosity - by adding foamed saponified carboxylic acid glyceride foam-stabilised with alkylol-amide or modified polysiloxane
Inventor: KRAUSS RALF HORST
IPC: C04B33/13
Filed: 1979-07-27
Abstract: In the prodn. of ceramic filter compsns. required ceramic filtering effect porosity is achieved by introducing foamed partly- or fully saponified glycerides, (A), of satd. and unsaturated carboxylic acids with the addn. of foam stabilisers, esp. fatty acid alkylolamides and polyalkylene glycol-modified polysiloxanes into the ceramic raw material before drying and fixing. Ceramic filters can replace standard material filters and in some cases active C filters. Filters which cannot be regenerated can be used as insulating or building materials. Pore size can be controlled to achieve pre-determined filtration properties and flow-rates. The low ceramic material cost is not increased. The filters can have desired shapes. High porosity of ceramic compsns. reduces firing times and energy consumption. The ceramic compsns. are resistant to aggressive materials and can be regenerated. Pollution during filter mfr. is prevented.

Title: Mining walking frame with lifting supports - has additional pivoted pendulum supports with automatic return into initial position
Inventor: MUELLER-KUEHN HELMUT
IPC: B62D57/00
Filed: 1979-09-12
Abstract: The walking frame has two groups of supports, alternately supporting a carrier frame, which are movable relative to each other for an advance movement. One group consists of longitudinally adjustable lifting supports. The second group consists of pendulum supports (5). When not loaded, the pendulum supports are in an initial non-vertical position, due to their own weight; but when loaded, they may be pivoted into a certain end position. The pendulum supports are non-centrally suspended from the carrier frame (2), and may be pivoted in one plane only. Near the suspension point (6,8) each support has two stops to limit the two positions.

Title: High quality toner developer for photocopier - has converging guide to feed powder to transfer zone and uses compressed bristles to improve transfer flow
Inventor: HORIE KIYOSHI
IPC: G03G13/09
Filed: 1979-12-17
Abstract: The high quality toner powder developer is for a photocopier and has a hoper feed (58) and a magnetic roller (54) to provide a constant stream of powder to the transfer zone (66) where it is applied to the process drum (10). A guide (64) restricts the flow of toner out of the zone and compresses the toner bristles to generate an improved transfer flow. The guide can be a simple flat plate or a roller to prevent clogging. The toner powder is a one component type. The transfer roller has a non-magnetic fixed cylinder (56) inside which the magnetic core (54) rotates, and picks up a constant stream of toner particles. The improvement can be applied to most types of hopper fed toner developers.

Patent DE-3013132-A1 (DE)
Title: Fuse unit for vehicle - has resettable fuses with push-buttons and overload-indicating lamps
Inventor: BUETTNER MICHAEL
IPC: H01H73/00
Filed: 1980-04-02
Abstract: The fuse unit uses resettable push-button fuses instead of melting ores and has indicator lamps lighting when its fuses are triggered. The driver can then see at a glance which circuit has been overloaded. Fuses do not need changing - only the push-buttons need operating to reset the fuses. Faults can be localised quickly. When an overload occurs in any circuit, that circuit's push-button springs out and its indicator lamp lights. The circuit is thereby broken. If the overload is temporary, the push-button can be reset. It not the button springs out again.

Title: Production of moisture-resistant, especially thin structural panels or boards
Inventor: LUX HERBERT
IPC: E04F13/08
Filed: 1981-02-12
Abstract: A further development of the process according to the application of 22.12.1975, application number P 2557632.3, relates to the production of multipurpose, water-resistant and frost-resistant structural panels which can be manufactured in a straight and curved form. According to the accompanying drawing, they result from the parallel arrangement of the grid-type fabric on the two outer surfaces of the structural panel which are connected in a form-fitting manner by means of mortar. They serve, without separating, to tension, brace and harden the panel surface, with the result that the core of the panel also allows for different material inserts, such as, for example, concrete, foam, plastic, metal, insulating materials or pipe ducts, as necessary. The grid-type-fabric reinforcement, which neither expands nor shrinks and preferably consists of glass fibres in rolls of sufficient length and width, guarantees a crease-free fall and intimate mortar bonding through sealing fabric strips, vertically and horizontally, and openings in a specific arrangement. The two panel surfaces may be manufactured, depending on requirements, to be smooth or rough (having a good grip) and can be subsequently coated, plastered, tapered or provided with ceramic plates. They can be nailed, screwed, mortared, adhesively bonded or used as permanent shuttering. <IMAGE>
