Title: Adjuster for brake cylinder dependent on play - comprises adjustment spindle secured against rotation in brake force transmission part
Inventor: MOESCHLER FRANZ
IPC: F16D65/56
Filed: 1989-11-23
Abstract: The adjustment device for a brake cylinder, partic. for railed vehicles, comprises an adjustment spindle secured against rotation in the transmission path of the brake force. A coupling nut (22) which is not spring-loaded is mounted on a similarly not spring-loaded roller bearing (23) and couples through toothed engagement with the rotationally secured coupling plates (18) which have a defined axial displacement. A stop spring (10) is supported on one side against an abutment designed as a tubular attachment (5) set on the front rigid part of the cylinder lid (4) which does not introduce the force. On the other side, the stop spring adjoins in the brake direction the disc (11) which has inner noses (12) which are mounted to project into the longitudinal slits (9) in the tubular attachment (5). An expanding spring (25) acts against the force of the stop spring.  This expanding spring is mounted between the coupling plate (18) and front spindle bearing (24). ADVANTAGE - Less complicated design.

Title: Welding of two overlapping thermoplastic sheets - in which welding cheek with relief pattern formed of raised bars and recesses retains majority of polymer during welding phase
Inventor: ABRAHAMSSON ANDERS
IPC: B29C65/00
Filed: 1989-12-12
Abstract: A device (D) for welding together the overlapping ends of two sheet materials is described. The welding cheek has a relief pattern formed in the working face and presses against one side of the two materials to be welded. On the other side of the materials is a corresp. plate against which the cheek can be pressed. The pattern is formed of bars which cross each other and create raised sections together with corresp. recesses between them. The total volumea of the recesses formed is sufficiently large to accept and retain the majority of molten material created during the welding operation. USE/ADVANTAGE - (D) can be used for welding together packages formed of one or more thermoplastic layers and containing fluid foodstuffs. (D) produces a durable weld between the overlapping layers of plastic. (D) exerts equal pressure over the whole surface and produces uniform heat distribution. Improved stiffness of the welded joint is obtained by retention of molten material under the welding cheek.

Title: Bending machine for iron wire for reinforced concrete - has wire fed over bending mandrel by roller linked directly to motor or via endless belt to powered roller
Inventor: CLOUP PHILIPPE
IPC: B21F1/00
Filed: 1990-04-24
Abstract: The bending machine for metal wire esp. iron wire for reinforced concrete, has a table (2) with a circular opening (13) such that the wire is movable along a feed track on one side of which is a tubular bending mandrel (5).

Title: Electro magnetic desensitiser appts.
Inventor: SCHWARZ WERNER DIPL ING
IPC: G08B13/24
Filed: 1990-05-16
Abstract: The method magnetises a magnetically responsive marker of an electronic article surveillance system in which an alternating magnetic field is produced within an interrogation zone for interrogating a marker and a characteristic response produced by the activated marker in the zone is detected and used to produce an alarm signal. The marker comprises at least one magnetisable element which when magnetised causes a different response to be produced. The method comprises the steps of positioning the marker within a first magnetic field corresp. to that produced by the system for interrogating a marker, detecting the response from the marker and producing an active marker signal in the event that the response corresponds with the characteristic response required by the system to produce the alarm signal. Then applying a second magnetic field identified by its flux density to the magnetisable element to change its magnetic state, so altering the response and then applying the first field to the marker and detecting the response again and producing a deactivated marker signal.
Patent DE-4016696-A1 (DE)
Inventor: EIDLING KARL
IPC: H05K13/00
Filed: 1990-05-23
Abstract: The production of character generators for non-mechanical printers requires the positionally precise soldering of light-emitting diode chips (LEDs) on module plates. The precision required in all three dimensions lies between +/- 3 and 10  mu m. A new device is composed of an adjusting device (4) and a soldering device separable therefrom that can carry out as a separate unit a soldering operation. A LED-row to be soldered on a module plate is temporarily adjusted and held on an auxiliary carrier (5) and brought during the soldering operation towards the solder-coated surface of the module plate (carrier (6)) in such a way that the components being soldered are joined only after the solder (2) has melted. For that purpose, spring joints which can be blocked in two predetermined positions and also intermediate fusible disks which melt shortly after the solder (2) on the module plate are used, allowing the joining of the components being soldered to be controlled. As a result, mechanical damage to the LED-rows are avoided and a highly precise positioning of the LED-rows and the module plate is obtained.

Patent DE-4022940-A1 (DE)
Inventor: OTT KARL ING GRAD
IPC: F02D41/14
Filed: 1990-07-19
Abstract: The invention concerns a device for the temperature control of a heated wire or heated film used as the sensor resistance in an air-mass-flow measurement instrument in an internal-combustion engine. During measurement, the temperature of the current-carrying sensor resistance is kept at a particular level which is increased on completion of measurement, with the engine switched off, to allow free combustion, free combustion always occurring when a given sensor-resistance deposit/contamination level, which depends on the engine-operating parameters, is exceeded. To ensure a long sensor lifetime and high precision, the invention calls for the free combustion to be carried out when an adaptation parameter (Fra) dependent on an operating parameter changes by more than a given amount with respect to an adaptation mean value.

Title: Treatment of flue gas
Inventor: MENGES GEORG PROF DR ING
IPC: C07C273/04
Filed: 1990-08-18
Abstract: Prodn. of hydrocarbons from flue gas is effected by (a) burning the hydrocarbon and/or c-contg. components of the flue gas to obtain a gas contg. C02 and/or C0 and H20 vapour, and (b) using the gas for hydrocarbon synthesis. Pref. Step (a) is effected using a substoichiometric amt. of 02 to favour C0 formation. A reducing agent (esp.  waste oil or plastics) and H20 may be injected into the gas from step (a) to increase the C0 and H2 content. The amt of H20 injected is pref. sufficient to give an H20:C0 ratio of 1-15:3.  Step (b) is effected by reaction with H2 in the presence of a catalyst. The resulting hydrocarbons may be converted to HCHO.

IPC: E06B5/16
Filed: 1991-02-15
Abstract: A large, preferably transportable container which can be closed by a refractory sliding door consisting of a plurality of sliding leaves has a problem zone through which heat from a fire outside the container can enter the large container in the upper cover region in which runner rails for guiding rollers connected to the sliding leaves are mounted. The invention optimizes the fire resistance. To this end, a fireproof partition (10) arranged parallel to the sliding leaves (1, 2) is fixed to the cover (8) of the large container (7) across the whole width of the sliding door and projects into the space between the sliding leaves (1, 2). The fireproof partition (10) and the sliding leaves (1, 2) are provided with a layer of insulating elements (14) on the sides facing each other in the region of overlap. As a result, flames are prevented from entering the container directly through this region, and space between the sliding leaves and the fireproof partition (10) is closed by the layer of insulating elements to form an air lock.
