Title: Rotary magnet indicator for temp. measuring instrument display - applies trigonometric function from PWM control unit to first coil and complement of function to second coil to produce resultant field
Inventor: BLASCHKE ROBERT
IPC: G01R5/16
Filed: 1992-06-23
Abstract: A rotary magnet movement (M) for indicating the value of a physical parameter e.g. temperature w.r.t. a complete 360 deg. scale employs the resultant magnetic field of two coils (SP1,SP2) mounted mutually at right angles to determine the rest position of the magnet (M) and its attached pointer (2). An input parameter ( alpha ') from a sensor is applied to the function generator (1) which determines its value w.r.t. a 360 deg. scale and signals the required quadrant via a 2 Bit digital signal to a logic module (2). A PWM whose signals conform to the function: tan ( alpha ) / 1 + tan ( alpha ) combines with the digital signal in the logic module (2) for commensurate energisation of the coils (SP1,SP2) and resultant display ( alpha '). USE/ADVANTAGE - Operates on simplified trigonometric relationship resulting in control circuit cost reduction for full 360 deg. display. Coil currents are trigonometric complements of each other and sum to constant quantity which obviates need for voltage/current stabilisation.

Title: Drain cleaning equipment nozzle head - has ball and socket joint in hose connection fitting so that head remains flat on floor of drain-pipe when hose is pulled through bends
Inventor: STEINICKE EMILIA
IPC: B05B15/654
Filed: 1992-08-08
Abstract: The nozzles (7) of the nozzle head are directed backwards so that when pressurised water is fed through a hose connected to the head, the reaction force causes the head and hose to traverse along the drainpipe. In the hose connection fitting (3) is a ball and socket joint (5) permitting angular movement of the hose relative to the head. This angular movement allows the nozzle head to remain flat on the floor of the drainpipe when the hose takes up an angle due e.g. to being pulled through bends or up a manhole shaft. USE/ADVANTAGE - Reliable cleaning of drains without manual intervention.

Patent DE-4244252-A1 (DE)
Inventor: TESCH GUENTER
IPC: D04H1/64
Filed: 1992-12-27
Abstract: Described is a textile floor covering with mutually interconnected sphere-shaped fibre aggregates (modules) consisting of spherically entwined textile fibres, wherein the fibre aggregates are connected to one another and to the floor by a single binder. The floor covering is produced by laying a layer of spherically entwined, sphere-shaped fibre aggregates of textile fibres on the floor to be covered and securing the layer to the floor with a binder. This results in a floor covering which, compared with existing coverings, is less costly to produce and simpler to lay, but which, on the other hand, has the same structural and colouring possibilities as a carpet consisting of spherical yarns. <IMAGE>

Title: Core for precasting holes in castings, and the manufacture of the said core
Inventor: SEIDL HERBERT ING GRAD
IPC: B22C9/10
Filed: 1993-07-09
Abstract: A description is given of a core for precasting straight holes in castings, the said core comprising a metal bar encased in foundry moulding materials and being characterised in that the encasing moulding material has a green compression strength of at least 6N/cm<2> and is applied to the metal bar in a thickness of 0.3-3 mm. The core can have a diameter of 2-15 mm, preferably 3-12 mm, and a length of up to 500 mm. The new core is expediently produced by preparing the moulding material with a liquid to give a doughy mass and this mass is pressed onto the core iron with a pressure of 50-300 bar and then compacted. For this purpose, an extrusion die is provided, through which the moulding material is forced and, at the same time, the metal bar is passed centrally. With the new core it is possible to precast with great accuracy extremely thin and long holes, which with the prior art were producible only with great difficulty, if at all.
Patent DE-4332278-A1 (DE)
Title: Optical antitheft system for motor vehicles
Inventor: GODLEWSKI DIETMAR
IPC: G08B15/02
Filed: 1993-09-23
Abstract: The laminated glass windows installed in motor vehicles, which are composed of two panes which are inextricably linked with one another by means of a plastic film cannot be filled with a coloured gas. During production of laminated glass windows the interior plastic film can be provided with channels over part of its area. The coloured gas stored in a pressurised container can flow into the network of channels when the non-return valve is activated. When the network of channels has been filled, the glass is seen to become coloured in the region of the channels. The valves installed, the non-return valve and the pressure control valve ensure that the coloured gas is stored. When the motor vehicle is subjected to unauthorised use and the alarm system is switched on, the colouring given to the glass indicates to bystanders that its use and operation are illegal. Theft of motor vehicles can therefore be made much more difficult as a perpetrator would have to expect a stolen vehicle to be inspected, owing to the optical signals.
