Patent DE-4219869-A1 (DE)
Title: Method of mfg. car registration number plates - uses extended length of plastics foil strip for precise positioning of colouring regions and uses cutting and embossing tools
Inventor: UTSCH JOACHIM
IPC: G09F13/16
Filed: 1992-06-17
Abstract: For precise positioning of the painting of the peripheral edge of the sheet metal strip, or the plate symbols, an additional length is incorporated with the periodical spacings.

Title: Narrow fabric strap used for impact safety straps - has two complete side by side straps woven simultaneously and joined by a third weft yarn
Inventor: BRIELMANN ROLAND
IPC: D03D11/00
Filed: 1992-07-21
Abstract: Narrow fabrics (straps) are made by weaving at least two complete single straps simultaneously side by side and combining them with each other by a horizontal additional weft yarn. Two complete straps with their own selvedges are woven simultaneously with wefts inserted independently above each other. A 3rd weft yarn is inserted across both fabrics to link them in a loose zone. As the individual straps are complete, there is no thread slippage and high throughput is achieved without overstressing individual yarns. The strength and dimensions of the individual zones can be altered independently to satisfy the required end use. USE/ADVANTAGE - Partic. useful for impact safety straps where the connecting weft is allowed to tear and absorb energy while the individual straps are still able to support a load.

Title: Prodn. of refractory magnesite casting material - by mixing magnesite grains with synthetic silicon di:oxide gives material  resistant to water hydration
Inventor: FLEISCHMANN WERNER DIPL ING
IPC: C04B35/66

Patent DE-4302118-A1 (DE)
Inventor: HACKER ERICH
IPC: G11B7/24
Filed: 1993-01-27
Abstract: An optical store comprises at least one radiation-absorbing, photothermally (and/or photochemically) reactive layer which is enclosed between an upper layer structure and a lower layer structure. The upper layer structure allows the substantially unimpeded penetration of radiation flux into the absorbing layer whilst the lower layer structure blocks the radiation flux from passing into an underlying substrate. The absorbing layer comprises any desired absorbing substance, preferably of a material which is mechanically and chemically resistant and which has stable optical properties, eg aluminium or chrome. In specific examples the first layer structure is formed of layers of Si3N4 and MgF2 or layers of TiO2 and MgF2 whilst the second layer structure is formed of layers of TiO2 and MgF2.

Abstract: A synchronous machine includes a stator wound with a first winding A and a second winding B in double-layer winding (Figs 6, 9 12, 25 and 29), a rotor having a salient pole shape and rotatably received in said stator, a first controller 111 for controlling the speed of the machine as a power source of said first winding A, and a second controller 131 for controlling output value to torque value of the machine as a power source of said second winding B. Interference between winding A and B can be reduced by insulation material (211, fig 9) which has a strong magnetic reluctance. The machine may be a motor 101, a generator (Fig 30 and 31) having a constant output voltage control circuit, or in a further aspect a linear motor (Fig 29). Further speed and position control systems are described (Figs 20, 21 and 22). In a further aspect an armature winding proceeds by an angle of 90{ in electrical phase from a field winding. An armature winding (19, Fig 23) is fed with those phase current and when the speed of the motor (101) reaches synchronous speed an electromagnetic switch (223) operates to supply a winding (17) with a current that has a 90{ phase difference by means of capacitors (221). In a still further aspect the rotor of the motor is made from anisotropic magnetic body (Fig 15) being a salient pole shape (Fig 16), a segment type (Fig 17) an hybrid type (Fig 18) having air gaps (47), or in the shape of few magnetic poles (Fig 19). The rotor shaft of a motor (Fig. 26) is described as integral with the main spindle of a machine tool. The field and armature windings may be placed side by side (Figs 27 and 28).

Title: Two-door drum closure for a casing-loadable drum-type washing machine
Inventor: UNGER KLAUS DIPL ING
IPC: D06F37/10

Title: Method and arrangement for rendering the dust loading of a gas flow in a channel uniform
Inventor: STROEER KURT DIPL ING
IPC: F23K3/02
Filed: 1993-08-24
Abstract: The invention relates to a method and an arrangement for rendering the dust loading of a gas flow in a channel uniform, in particular a flow of a coal-dust/carrier-gas mixture in the channel before a coal-dust burner. In this method and arrangement, uniform dust charging before downstream installations is to be achieved. This is achieved in that, according to the invention, the boundary gas flow of the flow of coal-dust/carrier-gas mixture in the boundary region of the channel is retarded, partial gas flows are produced by means of passages and the main gas flow is deflected and also guided into the region of the centre of the channel. Before implementation, baffle elements and also clearance gaps are arranged in the boundary region of the channel and the baffle elements arranged in the region to the centre of the channel are equipped with directing means pointing in the flowing-off direction. <IMAGE>

Title: Safety belt system for pregnant women
Inventor: WIPPER ANDREAS DIPL ING
IPC: B60R22/26
Filed: 1994-03-31
Abstract: In vehicle accidents in road traffic, pregnant women are at great risk with or without having put on the conventional safety belt of a car. In accidents, the course of the belt across the stomach and the pelvis leads in most cases to pregnancy-related injuries. The invention solves the problem as the course of the belt of the two-part safety belt system for pregnant women (upper belt (1), lower belt (6)) guarantees a belt-free zone for the stomach region (pregnancy region) and the breast of the pregnant woman. The upper belt (1) runs, starting from the driving seat and seen in the direction of travel, out left from the belt retractor (3), away over the left shoulder, along above the breast, and through under the right arm to the belt clasp (5). The lower belt ends (12; 13) are screwed to standard fastening points of the vehicle. The central part of the lower belt (6) lies on the seat cushion (11), on which the pregnant woman sits. The front part runs via the groins of the pregnant woman. A second covering is additionally sewn on the seat back (4), under which the standard belt (14) of the respective vehicle runs. <IMAGE>
