Patent DE-3702887-A1 (DE)
Inventor: SCHEFFLER WILFRIED
IPC: G11B15/675
Filed: 1987-01-31
Abstract: It is conventional in relation to automatic retraction mechanisms to position a switch that advances a slide-out compartment in and out either on the front surface of the compartment or behind it at a fixed point inside the device where it can be activated by the compartment, which the operator applies pressure over a short distance to for that purpose. The object of the invention is accordingly to provide a reliable, cost-effective, and user-friendly solution. This object is attained with absolutely already existing components in that the retraction mechanism travels a short distance when pressed, accordingly rotating the rotor component of the motor (1) through the intermediary of the drive mechanism, a rack (3) and pinion (2) and if necessary a belt (4) for example, and causing it to generate electromagnetic force. The resulting pulse is processed in the form of a signal by a simple processing circuit (17) and supplied in the form of a switching command to controls, usually a microcomputer (18). The microcomputer turns on the motor voltage for a specific time and at a specific polarity.
Patent DE-3703133-A1 (DE)

IPC: H05B6/70
Filed: 1987-02-03
Abstract: The known methods for homogenising the field distribution in a cooking space heated by microwaves, such as rotating antennas, rotating plates and wave stirrers, are relatively expensive. The characteristic impedance is periodically changed by means of a rotating element (5) arranged in the waveguide (3) between the magnetron (1) and the injection aperture (6) into the cooking space (2). In this way, the output frequency of the magnetron is also changed, resulting in homogenisation of the field. <IMAGE>

Abstract: The concept of a generation of sports simulators of a competitive nature, provided by a computer and screen which deliver a picture, seen from the perspective of a competitor, of a simulated natural environment with bends, upward and downward slopes and an opponent seen from the rear, or, in a rear view mirror, from the front, as well as a competitor in the foreground, seen from the rear, whose movements are synchronized with those of the user, allowing said user to identify with him. Whilst the training apparatus, monitor images and, to some extent, the software programs of the individual sports vary from each other, the same hardware circuit may be used for the simulation of all the sports. The sports in question all involve passage over distance by means of muscular energy expended by the user, such as cycling, rowing, canoeing, cross-country skiing, swimming, running, climbing stairs and rock climbing. The surroundings represented in the pictures are suited to the sport which they accompany. There is a selection of modes of operation, some of them new, as well as feedback on the user's performance. Some of the training and exercise apparatus is known, some is new. Application to medicine, physiotherapy, physical training and maintenance of fitness.

Title: Process and apparatus for producing ceramic inlays
Inventor: GRICKSCHAT WALTER
IPC: B28B3/00
Filed: 1987-03-06
Abstract: The wax positive to be reproduced is pressed into the lower part 1, filled with self-curing embedding composition 3, of a two-part firing mould, then the upper part 2, likewise filled with self-curing embedding composition, is placed on top, taken off after curing, and fired together with the lower part and the wax is thereby removed. Both moulds are, after cooling, filled with an excess of a ceramic composition mixed into a paste, after they have been moistened beforehand with the liquid, preferably high-percentage ethanol, used for mixing the ceramic composition into a paste. Firing is then carried out in vacuo, the two parts of the mould being pressed against one another by mechanical pressure during firing and at least at the beginning of the cooling time. This continually forces sufficient extra ceramic material into the mould to compensate for the shrinkage caused by cooling and firing. The two parts of the mould 1 and 2 are preferably provided with mutually corresponding projections and recesses which are arranged in such a way that the two parts can only be placed on top of one another in a very particular orientation relative to one another. <IMAGE>

Title: Handle for a folding basket
Inventor: WIMMER RUDI
IPC: B65D5/46
Filed: 1987-04-11
Abstract: A handle for a folding basket made of cardboard, corrugated cardboard or similar material is described, which handle consists of a flexible bow onto whose ends a fastener is moulded in each case. These fasteners are inserted in opposite cutouts arranged on the longitudinal sides of the folding basket. Each fastener consists of a flat web whose upper edge facing the bow runs perpendicular to the axis of the bow. The web is divided by the bow into a long web section and a short web section. The side edge of the web starting from the corner of the upper edge of the short web section is rounded in a curved shape and merges into an essentially straight lower edge of the web. An undercut at the junction of the upper edge of the long section of the web and the adjacent side edge of the bow simplifies the introduction and centring of the fastener in the cutout at the upper edge of the basket.

Title: Process for disposing of, reprocessing and reclaiming plastic wastes and floor-covering element or similar mould parts produced by this means
Inventor: HEINLEIN HANS
IPC: E04F15/10
Filed: 1987-05-11
Abstract: In the reprocessing and reclamation of plastic wastes, it is generally not possible to combine plastics of widely differing types and origin with one another and produce durable products from this. With the new process, a readily processable, injection mouldable or compression mouldable basic material is to be produced from plastic wastes of any kind, which basic material can be relatively highly stressed and is suitable, for example, for producing non-foamed construction materials/construction elements/moulded articles/vessels or the like. Unsorted plastic wastes of widely differing type and origin are treated in that they are mixed with fillers/carrier substances/additives of such kinds and in such volume ratios that the widely differing plastic wastes are made bindable in further treatment. In particular, vegetable materials such as, for example, wood, sawdust, wood dust, cereal residues are used as fillers/carrier substances/additives. Disposal and reclamation of plastics waste; production of foot load-resistant floor-covering elements such as slabs, tiles or the like.

Title: Fuel injection valve
Inventor: FINSTERWALDER GERHARD
IPC: F02B3/06
Filed: 1988-04-29
Abstract: Commercially available fuel injection valves have no continuously controllable nozzle hole cross-sections. The nozzle hole cross-section is therefore a compromise between the optima at full load and idling, with disadvantages for fuel consumption and pollutant emissions. The solution lies in compensating for the pressure acting below the injection valve needle tip by means of a pressure piston (14), which is subjected to the injection pressure by way of a control valve (33) with no exposed annular area. The invention is suitable for all diesel engines. <IMAGE>

Title: Process, equipment and means for concentrating aggressive solutions
Inventor: LAINE TATU
IPC: C01D1/42
Filed: 1988-10-08
Abstract: The invention relates to a process, equipment and means for concentrating aggressive solutions such as alkali metal hydroxide solutions, e.g. NaOH or KOH, to give a highest possible concentration even of 80 to 99.8%, depending on the product desired, before it is converted to a solid form. When aggressive solutions are concentrated, the temperature at their boiling point increases greatly. Thus the initial concentration of such aggressive solutions is generally carried out with a steam whose pressure is higher than normal. With high-pressure steam, NaOH can be concentrated in practice up to about 75%. Concentration to higher concentrations is achieved according to the invention by pumping the solution to be concentrated into a flue gas evaporator (2) in order to flow through the tubes of a plurality of heating elements (22) arranged in a flue gas duct. The elements (22) are arranged, with respect to the solution to be concentrated, from the coldest to the hottest, the temperature and concentration of the solution being highest in the final element (22). The temperature of the hottest element (22) is above the solidification point of the solution to be concentrated; it is preferably at most about 400@C. The heating elements (22) are arranged stepwise from the coldest to the hottest, so that the hydrostatic overpressure which [lacuna] from the [lacuna] during the concentration of the alkali metal hydroxide solution ...
