Title: Vehicle antilock brake control valve - has pressure modulating membrane valve incorporating flow restriction
Inventor: REINARTZ HANS-DIETER
IPC: B60T8/34
Filed: 1990-05-25
Abstract: The anti-lock brake control includes a pressure control valve which operates on the pressure difference between the master brake cylinder and the wheel cylinder. The membrane is fitted with a control spring (17) on the wheel cylinder side and is pieced by a flow restriction (21). This ensures that the pressure rise pattern is accurately controlled in the pressure modulation phases. The flow restriction can be part of the membrane or can be incorporated in the membrane mounting itself. Alternately the flow restriction can be fitted on the membrane mounting. the anti-skid control is operated by solenoid valves normally upowered. ADVANTAGE - Simple pressure control system, improved brake control, less control circuit complexity.

Patent DE-4107813-A1 (DE)
Inventor: KEMPF BURKHARD DIPL ING
IPC: G01R31/00
Filed: 1991-03-11
Abstract: The invention relates to a method for testing a fitting (2a) driven by a solenoid (1a), which has a closing part (4a). It also relates to a device for testing such a fitting (2a). It is provided that during a switching process of the fitting (2a), the value of the current intensity (It) in the solenoid (1a) is recorded as operating current intensity (IA) at the time when the locking part (4a) starts to move. From this recorded operating current intensity (IA), the force acting due to the magnet (1a) on the locking part (4a) at the time when it starts to move is determined as operating force (KA). The force (KA) is compared with a setpoint and a signal is output when there is a deviation. The calibrating function (KF) is determined on a fitting (2b) of the same type in which the locking part (4b) is latched. The device for testing the fitting (2a) is distinguished by the fact that a current intensity meter (6a) in the circuit of the solenoid (1a) is connected to a computer (9) which is also connected to a memory (10) for a calibrating function (KF). The computer (9) is followed by a setpoint comparison section (11) and, for example, a signal generator (12). <IMAGE>

Title: Application of adhesive to edge of flat strip - involves use of pneumatic edge detector for upper and lower nozzles
Inventor: OLSSON PER-ERIK BERTIL
IPC: B05C3/20
Filed: 1991-06-07
Abstract: The strip (7) of foil, paper, cardboard, or similar flat material is coated with adhesive in the region near one edge. The strip (7) is guided by means of a pneumatic edge detector (2). This pneumatic edge detector (2) consists of an upper nozzle (3) which directs a jet of air into a lower nozzle (4). The upper nozzle (3) is connected to a source of compressed air (5) whilst the lower nozzle (4) is connected to a chamber (9) which is fitted with a flexible diaphragm. Any movement of the adhesive applicator head (19) and the attached nozzles (3) and (4) relative to the strip (7) varies the air flow between the nozzles (3) and (4). This in turn varies the pressure acting on the diaphragm which acts on the spring-loaded rod (12) to correct the position of the applicator head (1). USE - Application of adhesive to flat strips.

Patent DE-4138178-A1 (DE)
Inventor: ROHDE JOHANN HEINRICH
IPC: B21B17/04
Filed: 1991-11-15
Abstract: The invention relates to a method for the longitudinal rolling of seamless steel pipes (8) in a continuous rolling operation via an internal tool (2) in a multi-stand roll train, the rolls of the successive roll stands being installed offset relative to one another. In order to specify a method in which elongation sufficient to allow the production of double lengths of pipe with the minimum number of roll stands can be achieved, it is proposed that, in a first pass of just two successive rolling passes, a reduction in the wall thickness corresponding to or slightly less than the wall thickness of the finished pipe be made in the base (6) of the roll groove with the flanks (5) of the roll groove open, that, in the second roll pass, the flank region of the first roll pass be reduced in the transverse direction to the wall thickness of the finished pipe in the base of the roll groove of the second rolling pass, the circumferential enlargement of the tube due to the widening being reduced by stretching the pipe along its longitudinal axis without a reduction in wall thickness or with a slight reduction in wall thickness, by the simultaneous application of a controlled tensile force on the pipe between the two rolling passes. <IMAGE>
