Patent DE-4225680-A1 (DE)
Title: Method and appts. for cutting filter discs - with a coaxial stream of poorly reactive gas directed onto the focal spot on the filter material
Inventor: GRUNDMANN GEB BOCKEROTH
IPC: B23K26/364
Filed: 1992-08-04
Abstract: The method for cutting filter discs is characterised by the fact that cutting takes place without contact and without burning, by laser beam melting or sublimation of the filter fabric or filter membrane material, while a poorly reactive gas is blown coaxially with the laser beam onto the focal spot on the material being cut. The appts. includes a laser cutting head with a tubular end piece (6,7) having a converging outlet opening and an inlet branch for a poorly reactive gas. The preferred features of the method are covered by 18 subsidiary patent claims. For example, suction is used to remove the gases and resulting particles from the cutting gap. The polarisation plane of the laser beam and cutting direction are made to coincide for a maximum cutting rate. An integrated transport system (12,14,17) is provided for changing or supply of filter material strip (11) or sheets. At least two independently operable swivel mirrors are foreseen for cutting round filters of different diameters. USE/ADVANTAGE - In manufacture of filter elements, especially for medical and laboratory equipment. High-quality cut edges free of burrs are attained by means of a dust-free cutting process.

Title: Push-key combination lock
Inventor: UIHLEIN HERMANN
IPC: E05B37/16
Filed: 1993-05-05
Abstract: A mechanical number-combination lock can be opened by pressing code keys and subsequently the release key according to a particular code. If a bent piece of metal or a pin is introduced into the lock case or if the latch is moved, an unlocking element is pretensioned by spring pressure and, at the same time, the code keys are brought into a levelled initial position. The unlocking element is equipped with a perforation similar to a long hole, which, when the keys are pressed into a particular code, can engage into the recesses of the latter, then located at the same height, and allows a lateral movement of the unlocking element, thereby freeing the tumbler of the lock by means of the release key. In the position of rest, with the lock locked, the release key locks the unlocking element. This and the pretension which cannot be influenced from outside guarantee that the number code cannot be manipulated from outside. When the code keys are operated according to the particular code, the release key can be fully pressed and the lock tumbler thereby freed. The entire construction is kept extremely simple, thus allowing cost-effective production and simple operation.

Title: Filter blockage indicator incorporates movable membrane - which maintains its position even when internal combustion engine is switched off
Inventor: VAZ JAYME
IPC: G01L19/12
Filed: 1993-05-11
Abstract: An assembly indicates the degree of soiling in a combustion engine air filter and consists of a housing with a connector pipe, a return spring which presses against a movable membrane which is joined to an elastic piston. The novelty is that the membrane remains in its outer position even when there is no differential pressure. In the membrane an elastic piston is incorporated which can increase or decrease its capacity. The valve serves to maintain the indicator funtion when an internal combustion engine is inoperative. The membrane position can be inspected through a transparent wall. USE/ADVANTAGE - The assembly indicates the degree to which an automotive filter is blocked by measuring the pressure differential between the dirty and filtered side of the filter. An indication is supplied even if the engine is switched off.
Patent DE-4324912-A1 (DE)
Title: Actuating drive, in particular for heating valves, ventilation valves or air-conditioning valves in motor vehicles
Inventor: BERNREUTHER GEORG
IPC: F16K27/12
Filed: 1993-07-24
Abstract: An actuating drive, in particular for heating valves, ventilation valves or air-conditioning valves in motor vehicles, consisting of a drive housing, an electric motor having an integrated thrust bearing (pivot bearing), a step-down drive and an output drive shaft. In conventional actuating drives, O-ring seals are used to decouple body noise, but these are installed in a fixed position so that both the rotor as well as the stator are forced to adopt the predetermined position with respect to one another. If the motor tolerances interact unfavourably, it is possible for a bearing and a thrust washer to touch in this case, as a result of which the efficiency is reduced. The present invention is intended to overcome these disadvantages. This is done by the position of the stator not being influenced by receptacles in the drive housing and by at least one elastomer buffer being used which decouples the motor from body noise axially as well, this elastomer buffer being designed such that it can compensate for motor inaccuracies with the aid of a flexible region. <IMAGE>
Patent DE-4327239-A1 (DE)
Title: Shaping process
Inventor: WILLY ARMIN DIPL ING
IPC: B29C33/68
Filed: 1993-08-13
Abstract: The process serves for shaping a curved vulcanised tube. First of all, a straight tube is produced from crude rubber and then the straight tube is drawn onto a curved shaping mandrel. Then the shaping mandrel and the drawn-on tube are introduced into an autoclave for vulcanisation. Finally, the vulcanised tube is drawn off the shaping mandrel. Between the shaping mandrel and the tube there is introduced an auxiliary tube with good sliding properties, which has a low friction coefficient when sliding on the material of the shaping mandrel. The auxiliary tube likewise has a low friction coefficient in relation to the tube.
