Patent DE-3130164-A1 (DE)
Title: Pram/push-chair
Inventor: GLAESER DIETER
IPC: B62B9/18
Filed: 1981-07-30
Abstract: The invention relates to a pram/push-chair with an upper frame which bears a mount and is connected to a lower frame, which bears running wheels, by suspension devices which are arranged on both sides in the region above the running wheels and permit a resilient relative movement. To achieve energy absorption within a short time, with few oscillations and with low maximum amplitudes, each suspension device is designed as a belt loop which is attached captively by one end to the upper frame or to the lower frame and by the loop-shaped other end embraces a peg attached to the lower frame or upper frame. The belt loop can advantageously be formed from a belt made of a mesh of plastic threads. In a favourable development, outside the captively fixed, double-layered end of the belt loop a stop is provided which is fixedly connected to the fixed end of the belt loop and from the fixing point extends over a certain distance along the belt strand lying on the outside at the fixing point and is arranged in such a manner that when the upper frame performs a downwards movement relative to the lower frame the said stop, after a specified distance, comes to bear against the belt strand. A further advantageous development is given by the fact that the upper frame and the lower frame are additionally connected on each side by at least one catching element which limits relative movements transversely to the direction of travel and divergent movements of upper frame and lower frame in the vertical direction to a specified extent.
Patent DE-3130449-A1 (DE)
Title: Polariser
Inventor: LANGE WERNER DR DIPL ING
IPC: H01P1/165
Filed: 1981-07-23
Abstract: In the case of a polariser, the polarisation change of electromagnetic waves in waveguides or waveguide emitters, preferably the conversion of linear polarisation into circular polarisation and vice versa, is produced by deforming the waveguide cross-section. In order to achieve a reproducibly highly accurate deformation of the waveguide cross-section irrespective of fluctuations in the waveguide material properties and/or diameter in a manner which is as simple and cost-saving as possible, the waveguide is surrounded by a collar whose material is harder than that of the waveguide, and whose inner surface, which is constructed to correspond to it, is pressed against the waveguide outer surface in such a manner that the intended change in the waveguide cross-section is produced. In the case of a particularly simple configuration, which can be used with sufficient accuracy in most practical applications, for pinching circular waveguides, the inner surfaces of the collar form a rectangle in the cross-section, at least in the pinching region, the longer sides of which rectangle correspond to the external diameter of the circular waveguide.

Patent DE-3142488-A1 (DE)
Title: Method of electrolytically graining aluminium plates or strips by means of alternating current and constant cathode potential
IPC: C25F3/04
Filed: 1981-10-27
Abstract: A method of graining aluminium surfaces in an acidic electrolyte which can be used mainly in the surface treatment of aluminium in the production of lithographic printing plates, electrolytic capacitors and other fields of application ensures that a fine, uniform graining is produced on the aluminium surface. The uniform graining is achieved by immersing the aluminium in an aqueous acidic electrolyte and subjecting it to variable alternating current density. The alternating current can be varied to the extent that it is regulated by a potential established at the aluminium surface. In other words, if an aluminium surface is subjected to an alternating current in an acidic electrolyte, the electrochemical potential of the aluminium changes. The potential is monitored by means of reference electrodes which are placed in the vicinity of the aluminium surface. The measured values obtained from the reference electrodes are electronically processed and used to regulate the alternating current transformers. If the alternating current density is regulated in such a way that a constant cathode potential change is achieved throughout the process, the surface of the aluminium is finely and uniformly grained.

Title: Facing board for producing curtain-type or laid-on back-ventilated surface claddings
IPC: B32B13/12
Filed: 1982-01-11
Abstract: Facing board for producing curtain-type or laid-on back-ventilated surface claddings consisting of a backing slab of acrylic concrete onto which a decorative cover layer is applied so as to be integrally bonded and which is provided with fastening means for anchoring to the wall, the backing slab (1) made of filled acrylic concrete being provided on the visible side with a coating (2) of an unfilled coat of acrylic resin (laminate) coloured by pigmenting or by other means.

Patent DE-3206478-A1 (DE)
Title: Device for drawing off yarn ends on textile bobbins
Inventor: VOELLM ERNST
IPC: B65H67/08
Filed: 1982-02-23
Abstract: The device comprises a suction nozzle (8) having a slit-shaped suction mouth (15). In the region of the suction mouth (15) is located a pressure chamber (14) which extends over the width of the suction nozzle (8) and is subjected to compressed air and on the inner wall (16) of which, aligned with the inner wall of the suction nozzle (8), are arranged a number of pressure nozzles (17) having a nozzle axis inclined slightly relative to the axis of the suction nozzle (8). An injector effect is generated by the air jets entering the interior of the suction nozzle from the pressure nozzles (17). In the event of a yarn interruption, for example a yarn break or yarn cut, the suction nozzle (8) has to draw off the yarn end during the reverse rotation of the yarn bobbins. As a result of the injector effect of the air jets issuing from the pressure nozzles (17), the pull exerted on the yarn end is increased considerably without any adverse increase of the suction flow in the suction mouth (15), so that, even if catching occurs, the formation of a contrary roll and therefore a fault which can be rectified only manually are usually avoided. <IMAGE>

Title: Process for producing coin blanks
Inventor: RUSCOE MICHAEL J H
IPC: B23P15/00
Filed: 1982-07-20
Abstract: In a process for producing coin blanks for minting coins, a multiplicity of appropriately disc-shaped or plate-shaped metal cores is heated in order to reduce their hardness to less than about 65 according to the Rockwell 30T hardness scale, and the heated cores are then cooled so that they have the indicated hardness. The cooled cores are then filled into an electrically non-conductive perforated container which is then introduced into an electroplating bath. During a to-and-fro rotation of the container about a horizontal axis, a metallic coating having a layer thickness of at least about 0.01 mm is electrically deposited on the two surfaces of each core, and in about 2 to 4 times this thickness on the peripheral rim of each core. The cores provided with the coating are then taken out of the container.
Patent DE-3227177-A1 (DE)
Title: Centrifugal mill
Inventor: SCHYMURA KONRAD
IPC: B02C17/08
Filed: 1982-07-21
Abstract: The horizontal, cylindrical grinding drums rotate about their own drum axes and simultaneously on circles of rotation with constant rotation ratio r = -1 about a stationary axis of rotation parallel to the drum axis, and thus execute no absolute rotary motion about their own axis. The distances of the drum axes from the axes of rotation are smaller than the radii of the grinding drums, the grinding drums being attached to links, and the ends of the links to eccentrics. To prevent imbalance and to reduce the dead weight, a first grinding drum is fastened by a first link at each end to a first eccentric, a second grinding drum is fastened by a second link at each end to a second eccentric, and the first and second eccentrics are mutually offset by 180 DEG , each arranged on an eccentric shaft, and the links are constructed such that no contact arises between the first grinding drum and the second link or between the second grinding drum and the first link during the countermotion.

Title: Wide-band studs on sports shoes
Inventor: MATULLA KONRAD ED
IPC: A43C15/16
Filed: 1982-09-29
Abstract: The new stud material and changed shapes serve to produce better effects in the following aspects:   1. Improved, safer starting power, reduced erosion of playing field turf, and reduced physical injuries in the event of impacts against parts of the body. 2. A contribution to this is made by the wide-band elongate surfaces and by their type of changed physical shapes, such as, inter alia, twin studs as in P3235986.1, and also by their selected positioning in a horseshoe or circular shape on the sole part, since here the stud surround is encircled by bottom surfaces via which slipping is prevented, even with short ground penetration depths, and physical impacts are also moderated. All these values relate to existing stud material in round mandrel-shaped form of about 10 to 12 m in average length up to 16 mm, referred to as so-called "screw studs", and these cause the abovementioned defects, and therefore require stud reshapings such as are claimed by the inventor (in passing) as "safety studs". The subject has hitherto been known worldwide as damaging, and is now to be moderated.

Title: Apparatus and process for separating off foreign material from a gas
Inventor: DIACHUK WOLODYMYR
IPC: B04C3/04
Filed: 1982-12-20
Abstract: The apparatus is used in connection with a kitchen extractor hood in order to eliminate foreign material from gas which moves through the extractor hood and to transfer heat from the gas to a fluid. The apparatus has a heat-conducting wall (42) which surrounds a tubular duct for gas and foreign material. Helically coiled parts (51, 52, 53) are arranged offset at an angle to each other in the duct and divide the gas moving through the duct into separate helically coiled gas streams. A jacket (78) having a fluid reception chamber (84) surrounds the wall (42). Heat from the gas in the duct is transferred via the wall (42) to the fluid. The foreign material is separated off from the gas by centrifugal force, adhesion, condensation and impact effect. The foreign material collects on the wall (42) and is passed by the gas to a material collection ring (69) which is arranged at the outlet end of the wall. Purified gas flows via the material collection ring into the surroundings outside the apparatus. <IMAGE>

Title: System for changing the tyre pressure in motor vehicles
Inventor: NAGEL SIEGFRIED
IPC: B60C23/00
Filed: 1982-12-22
Abstract: In a system for changing the tyre pressure in vehicles, an electromagnetic switching valve is connected between a supply line for the compressed air source and a supply line to a compressed air-controlled valve on the vehicle wheel, which switching valve has, in contrast to the prior art, only two switch positions. The supply line is vented in the position of rest of the switching valve but in the working position it is connected to the supply line. Whether the tyre pressure is increased or lowered depends on the position of a shut-off valve which is connected to the supply line and downstream of which a pressure-limiting valve is connected. The system is also extremely well suited for controlling the tyre pressure as a function of different parameters and permits unacceptable conditions to be indicated to the driver.
