Patent DE-3642508-A1 (DE)
Title: Pneumatic cushion or pad
Inventor: STOSCHEK OLAF
IPC: A47C4/54
Filed: 1986-12-12
Abstract: The invention starts from a pneumatic pad or cushion provided with a cover and intended for seating furniture or the like, said pad or cushion being fitted with an inflatable body which can be inflated by a manually operable compressed-air generator. To be able to produce a cushion or pad of this type which can be inflated to a greater or lesser degree and, moreover, can even be regulated with respect to its air pressure, but which does not differ from other normal cushions or pads with respect to its appearance, the invention proposes to arrange the compressed-air generator together with the inflatable body in the cushion or pad. Furthermore, the inflatable body is provided with a pressure relief valve, so that pressurisation of the inflatable body from outside leads to an increase in the air pressure and hence to a triggering of the pressure relief valve. It is thus possible to reduce excessive internal pressure or obtain a pressureless inflatable body.

Title: Method for pressing tubes into tube plates from both sides with the aid of elastomers
Inventor: HORRIGHS WOLFGANG DR ING
IPC: B21D39/06
Filed: 1987-03-05
Abstract: To achieve quasi-hydraulic expansion pressures, the invention discloses a method for pressing tubes into tube plates in which, with the aid of a suitable pressing device, an elastomer situated within a tube is subjected from both sides to an axial compressive stress. In contrast to the hitherto known pressing method from one side, a symmetrical expansion pressure is thus achieved and, in addition, the maximum expansion pressures occur at the location of the maximum operating stress and the drop in expansion pressure over the height of the tube plate is considerably less due to the compressive action from both sides; this is advantageous particularly in the case of relatively thick tube plates. The invention accordingly relates to a quasi-hydraulic method which combines the advantages of the elastomer expansion method with those of hydraulic expansion in an ideal manner and thus relates to a tool for installing tubes rapidly in tube plates.
Patent DE-3716134-A1 (DE)
Title: Method of reworking cylindrical components
Inventor: SCHLEICH HANNS-WERNER
IPC: B23K9/032
Filed: 1987-05-14
Abstract: To rework pipes or components with a smooth surface, in particular from the mine operation of coal mines, sheet metal, preferably a sheet-metal tube, is slipped onto the turned area and is fixed to the cylindrical component by applying a weld by a laser beam. In the process, the cylindrical component is preferably rotated and also displaced so that a net-like distribution of the welds over the entire surface of the cylindrical component results. The new surface thus formed is then further machined in accordance with the conditions of use and if need be is refined by applying a corrosion-resistant coating. The sheet metal or sheet-metal tube applied has a thickness greater than the twisting-off strength so that specific further working is possible. The joining or welding by laser beam is possible through the sheet metal so that a very uniform surface forms after the fixing of the sheet metal to the cylindrical-component surface machined beforehand, i.e. the turned surface. The requisite further machining operations are thereby simplified. <IMAGE>

Title: Sliding sleeve for a speed governor
Inventor: BURGGRAEF HEINZ-DIETER
IPC: G05D13/16
Filed: 1987-07-30
Abstract: For reasons of strength, sliding sleeves which are used in speed governors are generally manufactured from sintered metal in order to transmit the adjusting movements from the measuring mechanism of the speed governor to the control lever. Sliding sleeves made from sintered metal have the disadvantage that owing to the high weight they have a detrimental influence on the control characteristic. These disadvantages are avoided by the sliding sleeve (7) according to the invention, in that it is composed of different materials. The basic body (9) is made from thermosetting plastic whereas in the area of the bearing points of the centrifugal weights (2) and the control lever (3), discs (4, 6) preferably of steel are fitted on the basic body (9) (Fig. 1). <IMAGE>

Title: Block and tackle with several blocks
Inventor: THEREMIN KLAUS DIPL ING
IPC: B66D3/04
Filed: 1987-10-27
Abstract: Block and tackle with several blocks, preferably for telescopic jib cranes. The aim of the invention is to utilise the carrying power of the telescopic jibs optimally in all forms of application of the jib with little effort by the operator required. The object is to create a block and tackle with several blocks that adapts variably to the carrying power of the individual telescopic positions. The invention consists in the block and tackle with several blocks being made up of a divisible upper block and a divisible lower block. Pulley units that can be detached sideways are arranged on the middle section of the lower block; when the head telescope member is extended, the pulley units are pulled against the side pulleys of the upper block with the hoisting gear and secured by a coupling device. The advantages consist in better utilisation of the jib's carrying power through the minimised dead weight of the upper and lower blocks when the end piece is extended, and in the minimum effort needed by the operator to refit. The invention can be employed in railway, road and mobile cranes with telescopic jibs. <IMAGE>

Patent DE-3814570-A1 (DE)
Inventor: SCHROEDER HARTMUT PROF DR ING
IPC: H04N5/21
Filed: 1988-04-29
Abstract: To improve the picture quality in a television receiver which displays the received television signal in accordance with the line interlace method, frame stores are increasingly used. The remaining system-related flicker disturbances caused by the line interlace method require different signal processing for stationary and moving frame sequences in known flicker reduction processes, in which the receiver switches from flicker-free to motion-correct 100-Hz field repetition rate even with a relatively slight movement. To reduce system-related line flicker disturbances with line interlace reproduction, the signals contained in the frame store are in each case divided by vertical filtering in the television receiver into a vertical high-frequency and low-frequency signal as determined by the position frequency, these signals are differently processed in dependence on movement and the processed high-frequency and low-frequency signals are reproduced with twice the vertical frequency in line interlace. The flicker reduction method according to the invention can be used in all television receivers in which the television signal is reproduced at twice the vertical frequency in line interlace. <IMAGE>

Title: Method for repairing asphalt roadways and a machine therefor
Inventor: DIEHL KLAUS DIPL ING
IPC: E01C23/06
Filed: 1988-05-03
Abstract: In the method, to avoid weather-dependent performance fluctuations, to save energy and to simplify the sequence of operations involved in the reuse of coverings, the removed covering material is heated to the preset processing temperature in a heat exchanger, preferably an oil-fired heat exchanger, shielded from the disadvantageous weather and atmospheric-oxygen influences and the original roadway covering is then restored. For the purpose of material improvement, preferably pourable, pre-bituminised additional material is added in the required composition and amount. To carry out the method, road cutters equipped with tearing teeth and having downstream scraping devices are situated in the front part of an automotive working machine for covering removal. Situated at the centre of the chassis is a heat exchanger in which the scraped-off material absorbs, during the transportation by means of conveying worms to the levelling and re-compacting devices, from the walls of the conveying trough the heat produced by combustion of an oil/air mixture and is thereby heated to a processing temperature.   For the purpose of destruction-free removal, the roadway covering is heated by a radiant heating apparatus which is remotely controlled from the control console of the working machine and is placed in front at a working distance s dependent upon the heat penetration time.

Patent DE-3902384-A1 (DE)
Title: Impact absorber for motor vehicles
Inventor: STELZER HEINZ
IPC: F16F9/32
Filed: 1989-01-27
Abstract: An impact absorber (1) of a motor vehicle is described, which is composed of a cylinder (2) which is fastened to the vehicle frame and has a displaceable piston (8). The latter separates the liquid-filled space inside the cylinder (2) into two chambers (11) and (12). The liquid flows through an axially continuous aperture (9) in the piston (8) as soon as the latter is displaced. This movement is initiated by a bumper bar (10) which is fixedly connected to the piston (8). Opposite the bumper bar (10) there is situated along the cylinder (2) a corrugated pipe section (4) which is deformed together with the bumper bar (10) to produce a barrier as the impact speed of the motor vehicle increases. This means that, in the event of a collision, the kinetic energy is dissipated by a means which is additional to the shock-absorbing aperture (9). Loading of the corrugated pipe section (4) using a liquid has the advantage that the corrugated pipe section (4) is evenly loaded, independently of manufacturing tolerances and inaccuracies. <IMAGE>
