Title: Load-carrying structure for high pressure and high speed presses, especially for the production of ceramic products and similar products
Inventor: WALCHHUTTER ULRICO
IPC: B30B15/04
Filed: 1983-06-22
Abstract: Load-carrying structure intended for high pressure, high speed presses, especially for the production of ceramic and/or fireproof products, which comprises a bed, from which rise two vertical, parallel columns on whose upper ends a stationary crossbar is fastened, and a power unit. This power unit is attached to the lower portion of the stationary crossbar and carries a movable crossbar in the lower region. The movable crossbar is provided with press dies and is freely adjustable in the vertical direction in order to raise the press dies from the operating position in which they press the mass in the press dies on the bed into the inoperative position in which the press parts are taken out of the press dies and the press dies are filled with powdery material. The columns between the bed and the stationary crossbar consist of cylinders which penetrate into the bed and project upwards over this crossbar, and of sleeves which enclose the cylinder between the bed and the crossbar and support the crossbar on the bed. Stop nuts on both ends of each cylinder keep the whole cylinder under prestress and, at the same time, keep the sleeve under initial pressure.

Title: Adjustable, modular luggage rack for motor cycles
Inventor: TYRRA GUENTER
IPC: B62J7/00
Filed: 1983-07-08
Abstract: The field of application of the retrofittable luggage rack are motorcycles which do not have a luggage rack as a feature of series production. The problem resides in the large variety of models and the high speed of change of motorcycles on offer. As a result, it is hardly possible to quickly supply a suitable luggage rack for older models and the latest models. The solution has been conceived such that by combining various individual components of a luggage rack, which components vary in length, width and height, luggage racks of different sizes can be assembled by screw connections. All the individual components of the luggage rack are screwed to the four faces of a hollow square profile, the bearing part of the luggage rack. The screw connections in oblong holes provide a further adjustment and adaption facility. The nuts of the screw connections are located invisibly inside the hollow profile.

Patent DE-3329462-A1 (DE)
IPC: F16H55/17
Filed: 1983-08-16
Abstract: In order to improve the efficiency in the transmission of potentials of differents types, it is possible to implement transmission elements and a method with an ideal configuration as to the space-time-dynamics in all technical fields. In the method 1, the global configuration of the transmission elements, for example toothed wheels, is modified so that they are separated into two or a plurality of elements having the same operation mode, with out-of-phase actuation, so that the potential to be transmitted is brought at the ideal set time, from the transmission element having a lower efficiency to that which has a higher efficiency. In the method (2), the global configuration of the transmission elements is modified so that their ratios as to the path, the surface or the volume during the unequal efficiency cycles are ideally determined from the spatial point of view as a function of the angle covered (for example a crank-shaft angle). The increase of the effective path or surface during the higher efficiency period and the reduction of the effective path or surface during the lower efficiency period enable to obtain efficiency gains. Thereby, a favorable torque is obtained, for example in the case of a bicycle, by means of an elliptic driving gear.

Patent DE-3341952-A1 (DE)
Inventor: SCHOENHERR ANDREAS DIPL ING
IPC: H02P1/30
Filed: 1983-11-21
Abstract: In order to maintain the flux in an asynchronous machine supplied by an intermediate-link converter in the event of a network disturbance, the converter is initially blocked at the beginning of the network disturbance. After the intermediate-link current has decayed, the timing of the free-running converter on the machine side and the ignition of two series-connected controlled rectifiers of the converter on the network side are effected. The flux still present in the machine induces in the stator circuit closed in this manner a machine current which is controlled by a supplemental current controller in an operation slightly on the generator side, whereby, at the expense of the kinetic energy of the synchronized machine, a current through the circuit is generated which is required for covering the dielectric losses and for maintaining the desired flux.

Patent DE-3411379-A1 (DE)
Title: Roof tiles as solar collectors
IPC: E04D13/18
Filed: 1984-03-28
Abstract: It is shown in this invention how a steam generating plant can be constructed by means of the roof tiles. For this purpose a liquid must flow through pipes which bear against the roof tiles in order to take up heat, and has a boiling point so low that it evaporates before it has reached the roof ridge, or before it has reached the upper openings of the pipes. The vapour must however pass through a coil situated in the pipe, so that it has a high density at the upper pipe openings when coming out of these. Here it impinges on vanes which are attached to a shaft transverse to the flow direction of the evaporator liquid (located on the shaft) and pushes the vanes backwards, thus turning the shaft. This rotation is transmitted, for current production, to a generator outside the closed circulation of the evaporator liquid. A coolant flows underneath the shaft through pipes provided with cooling fins, in order to condense this steam again so that the circulation can begin anew.

Title: Magnetron cathode for cathode-sputtering systems
Inventor: DEPPISCH GERD ING GRAD
IPC: H01J37/34
Filed: 1984-03-29
Abstract: Magnetron cathode for cathode-sputtering systems having a target holder (10) for detachable mounting of a wafer-shaped target (9). The corresponding magnet configuration (7) has pole faces (7c, 7d) for generating at least one annularly closed tunnel of magnetic field lines which extends beyond the target. The magnet configuration (7) is accommodated in a housing of non-ferromagnetic material which extends over the pole faces. To achieve the object of increasing the utilisation factor of the target material without the pole faces or parts of the housing being involved in the sputtering process, the following is proposed according to the invention:   a) the projections of target (9) and pole faces (7c, 7d) in a common plane parallel to the target surface (9a) do not intersect, b) the housing (16) in the region of the pole faces (7c, 7d) extends beyond the target surface (9a) in the sputtering direction, or in the extreme case is in the plane of the target surface (9a), and c) the housing (16) with the magnet system (7) is electrically insulated, both with respect to the target holder (10) and with respect to chassis (4).   <IMAGE>

Title: Self-sealing housing closure
IPC: F16K27/04
Filed: 1984-08-28
Abstract: In order to guarantee good sealing in the case of self-sealing housing closures for sliding valves, even in the case of a renewed pressure rise in the interior of the housing, the closure cover 2 of the housing 1 is prestressed. For this purpose, the closure cover 2 has an annular flange 7 projecting radially outwards. Between the upper end face 9 of the annular flange 7 and a pressure ring 12 clamped against the end face 11 of the housing opening there is an upper seal ring 10. Between the housing-side end face 8 and an inward-projecting housing projection 5 there can be a further, lower seal ring 6. In the event of a pressure drop in the interior of the housing 1, the two seal rings 6, 10 are pressed against the annular flange 7 with approximately the same force. In the event of a renewed pressure rise, the lower seal ring 6 is relieved, while the upper seal ring 10 is loaded to approximately the same degree. The closure cover 2 is displaced to only an extremely slight extent relative to the spindle 3. <IMAGE>

Title: Delphin-type unit for removing small-scale and large-scale waste from water by suction
Inventor: SAVIC SERGIJE
IPC: C02F7/00
Filed: 1984-11-10
Abstract: The essence of the invention is constituted by the completely new type of protection for man against water pollution from rivers, lakes and the sea (coastal waters) and from all other sources of pollution. This is effected before discharging the water from the factories, harbours and built-up areas, etc. The novel technical solution allows man's environment to be protected by removing various polluting elements from the water by suction and depositing them in a collecting container. Depending on their type, these collected wastes can be further processed to produce an artificial fertiliser or can be deposited underground. Eliminating earth's most significant pollution factors and maintaining living conditions would give back life its original quality and richness, be this with regard to nourishment, to the perpetuation of plant life and animal life, but in particular of man himself.
