Title: Serving trolley with two movable and two fixed legs - has upper and lower trays, side struts and lengthwise strut
Inventor: WILD WERNER
IPC: A47B31/04
Filed: 1992-01-04
Abstract: The serving-trolley (1) has four legs (2, 3) which have four wheels (4) on the bottom.

Title: Mains independent braking circuit for series wound or universal motor - having split or single field winding and armature also at least one 2-pole changeover switch having three pairs of contacts
Inventor: SCHROECKER RAINER DIPL ING
IPC: H02P3/06
Filed: 1992-01-16
Abstract: Each change contact (6,7), together with the associated lazy contact (8,9), forms a normally closed switch and, together with the associated working contact (11,12), forms a normally open switch. A storage unit (25) serves for the compulsory starting of the self-excitation, and is charged by the mains voltage during the mains operation. After the change-over to braking mode, the corresp. part of the field winding (3) and the armature (2) lie in a continuously closed current circuit. A diode (23) lies in parallel to the corresp. part of the field winding (3) in the braking mode. The diode is so poled that current does not flow through it from the current circuit. ADVANTAGE - Reliably prevents collapse of self-excitation during braking due to diode lying in parallel with field winding.

Title: Variable section wing for hang-glider - has two separate lift surfaces for high and low speed flight
Inventor: SCHOLZ LUDWIG
IPC: B64C31/028
Filed: 1992-02-20
Abstract: The cross-section of the wing has two lift areas i.e. (70 and (5). The first area (1) is fixed to the various structural tubes (2,3) and a keel member. The second area (5) forms a secondary lift surface which is adjustable to the flight stage. For slow flight eg landing or take off the surface would be pulled through cables to a position near a line (6) thus increasing effective wing area. At high speeds this surface would not be necessary and is therefore released so as to trail behind the wind. USE/ADVANAGE - Wing for long-glider has secondary lift area which is allowed to trail freshly at high speed, to reduce drag and unnecessary lift.

Title: Production of mouldings from disintegrated used tyres etc. - comprises mixing particles of scrap material with water-soluble filler, then with e.g. polyurethane reagents and finally blowing agent, and moulding.
IPC: B32B25/00
Filed: 1992-07-31
Abstract: Mouldings are produced from disintegrated or ground used solid tyres, in which the particles are mixed with hard-setting cured resin that completely or partly fills the interstices between the particles and acts as binder; in the process the rubber scrap or pieces are mixed together while the binder such as diisocyanate and polyols plus blowing agent are added separately and sprayed into the mixer; after mixing further the material is added to a mould for curing and, where appropriate, a film or covering is applied to at least one side of it. In addition, a preferably water-soluble filler or additive is also mixed in, particularly e.g. potato starch, sugar, dextrins, size or similar. Pref., the example shown is a long cylindrical body (1) produced from a mould; it can be peeled to wide sheeting (2) of required thickness and this can then be used as a wall and/or floor covering etc. The material is made from e.g. granules, cut strips etc. of used tyres which are suitably e.g. ground and mixed. ADVANTAGE - The procedure makes it possible to produce e.g. sheets for walls and/or floors which can be processed or laid without difficulty, even if they have a porous structure. In particular they do not tear in use. The elasticity of the products is not attainable with products obtained by normal methods. The substances added are environmentally quite harmless.

Patent DE-4236488-A1 (DE)
Inventor: WEDDING BERTHOLD DIPL PHYS DR
IPC: H04B10/18
Filed: 1992-10-29
Abstract: In the optical transmission of a digital signal via an optical waveguide (3) which is dispersive at the operating wavelength, by means of an optical transmitter (2), the output signal of which is frequency modulated (FSK-modulated in this case) by the digital signal, there is at the end of the optical waveguide link a difference  DELTA  tau  in the delay of the two wave trains which occur in the FSK modulation. The electrical output signal V of an opto-electrical transducer (5) at the receiving end is intensity-modulated and passes through three value ranges. To retrieve the digital signal from this, a circuit (6) according to the invention is used, the output of which assumes a first state when a sample is in the first value range, the output of which assumes a second stage when a sample is in the second value range and the output of which assumes the state which occurred N bits previously at the same output when a sample is in the third value range. <IMAGE>

Title: Making efficient fit between tyre and its mounting rim - by subjecting their contact area to high frequency vibration through mechanical belt drive system with one unbalanced shaft
Inventor: MAHLING ROLF
IPC: B60C15/02
Filed: 1992-11-24
Abstract: The fit of a tyre on its rim is made efficiently by subjecting at least their mutual contact area to vibration.

The shaft (5) is belt-driven from a pulley to prevent vibration of the motor. ADVANTAGE - The process overcomes the prevalent problems e.g. the small variations in contact area and consequently in recovery/elasticity there, their effects from high friction, their variations in time etc..

Title: Apparatus for the cooling of hot steam
Inventor: APPELBERG FERDINAND
IPC: F22G5/12
Filed: 1993-04-22
Abstract: The invention relates to an apparatus for the cooling of hot steam flowing through a pipeline (1), with an elongate nozzle rack (2) which projects into the pipeline (1) transversely to the direction of flow and which has water-passage orifices (5), the water feed of which can be regulated by means of a control member (10) projecting axially into the nozzle rack (2), and which is surrounded at a distance by a casing (3) which can be loaded with driving steam, the water-passage orifices (5) being assigned water-atomising devices. In order, in an apparatus of this type, at as low an outlay in terms of the construction as possible, to achieve a fine atomisation of the cooling water which is as uniform as possible during each setting of the control member (10), whilst at the same time the adjustment travel of the control member (10) is to be as short as possible, the invention proposes that the water-passage orifices (5) in the nozzle rack (2) be arranged in at least one row closely next to one another in the direction of displacement of the control member (10), and that a water-atomising device common to all the water-passage orifices (5) has a baffle plate (12) which is inserted into the casing (3) and which has an inclined baffle surface (14) opposite the water-passage orifices (5) and leaves free outlet orifices (13) for the water/driving-steam mixture. The fed cooling water is thereby finely atomised during each setting of the control member (10). Moreover, a short adjustment travel of the control member (10) can be brought about. <IMAGE>
