Title: Car handbrake - has electric motor for operating brake shoes and detectors to determine position of gear shift, clutch, accelerator pedal
Inventor: NAGLER FRANZ DIPL ING
IPC: B60T7/10
Filed: 1992-06-06
Abstract: The hand brake of a car has an electric motor for the actual brake shoes and detectors for various driving parameters like the position of the accelerator pedal. neutral position of gear shift, engine stationary, etc. There is also the handle itself to activate the motor. With higher engine speed, or a greater accelerator pedal position, the speed with which the motor releases the brake shoes is increased in steps. A "starting situation" is defined when the gear shift is not in the neutral position, the accelerator position is not in the rear position and the engine speed is greater than idling. Clutch engagement can be an additional requirement for a "starting situation". ADVANTAGE - Car is automatically braked when stationary, with reduced wear on brake shoes.

Title: Pneumatic pressure-transmitting actuator with fast- and power-stroke - has low- and high-pressure component of equal dia.
Inventor: GRUELLMEIER ARTUR DIPL ING
IPC: F15B11/032
Filed: 1992-08-29
Abstract: The high pressure component consists of a cylinder (7), a piston (1) with seals (4), shock absorber rings (5,9,19) and a non-return valve (20) inside the supply port (10 E). The low pressure component consists of the cylinder barrel (12), the cylinder cap with tie rods (22), a piston with seals (15) and shock absorber rings. Compressed air passes through the supply port (10 E) to the high pressure cylinder (7) and moves the piston to the right. During the return stroke, the piston moves to the left at high speeds and compresses the air inside the cylinder thus generating the required forces for the power stroke. USE - In drives of die- stamp- and punching- machines and in clamping devices.

Title: Securing tunnel on foundation to prevent landslide - involves extrusion anchors in preset spacings, with injection carried out via anchor tubes
Inventor: SCHAUERTE WILHELM
IPC: E21D20/02
Filed: 1992-09-28
Abstract: The securing process inserts steel reinforcement in the form of anchors with simultaneous extrusion of an injection substance under high pressure. Over the length of the individual spaced anchors, the injection substrate is extruded through the tubular anchors and spaced non-return valves into the rock. Pref. flushing is applied during the anchor driving. After the driving, the bores (5) are cemented and subsequently expanded and injected for stiffening the rock. The two injection steps are carried out in sections via the non-return valves. USE/ADVANTAGE - For tunnels not located deep under the surface, with a facility to receive the rock in segments by reinforcing injection anchoring.

Title: Switching valve with regulation of output pressure - has inlet valve stage that closes when output pressure exceeds reference with vent valve stage opening to control pressure
Inventor: GOETTLING HELMUT DIPL ING
IPC: G05D16/20
Filed: 1992-09-23
Abstract: A fluid power valve has the fluid transferred from inlet (6a) to outlet (A) by the opening of a poppet (12) that has a piston (4a) displaced by a control signal (17). The pressure in the output chamber is monitored by a pressure sensor (19) and the valve compared with a reference value. So long as the reference is greater than the actual value, the valve remains open. When the actual begins to exceed the reference the inlet valve closes and an exhaust valve (13a,3a) opens due to a force differential and flow is unloaded (R) to lower the output pressure. USE/ADVANTAGE - For pneumatic-controlled braking or switching processes, with improved response and threshold times. Controls output pressure of switched valve.
Patent DE-4233372-A1 (DE)
Title: Washing contaminated thermoplastic film strips - by passing with liquid through hydrocyclone, sepg liq and disintegrating film, filtering and partly recirculating liq
Inventor: BUZGA HEINRICH
IPC: B04C5/13
Filed: 1992-10-05
Abstract: Contaminated and disintegrated thermoplastic films are washed in a liquid which is passed through a hydrocyclone and a frictional separator to secondary disintegration and further treatment. The liquid concerned is pumped up to a deodetic height of 1.0-10.0 m or more above the hydrocyclone; the films in strips 50-700 mm (pref. 500 mm) wide and 0.5-6.0 m (pref. 3.0 m) long are fed at this height into the liq. in a ratio of greater than 1:5 strips:liquid; the mix then falls freely to a nozzle-shaped overflow on the hydrocyclone. The layout feeds the strips of film in (17) to a pipe-line (18) at height (H) above a hydrocyclone (1) which has a top overflow (2) and bottom outlet (4) fitted with double-sliding plate below (5). The strips are passed by an overflow (2) through a pipe (7) to a frictional separator (8) where liquid adhering to them is removed. The dewatered strips pass to a sec. disintegrator (10) and from there to the user equipment. The liquid removed flows (12) to a filter (13) and dirt is separated (14). The filtered liquid is finally pumped (15) and recirculated. Energy is saved by diverting some of the liquid (22) back to the hydrocyclone directly (19). ADVANTAGE - The procedure is a simple way of reliably washing film in strips in a turbulent liq. (without the existing problem of agglomerating into lumps).

Patent DE-4237217-A1 (DE)
Title: Payout for filling closed casting moulds with plasticised melt - feeds melt from e.g. extruder through two-way valve to fill pressure chamber and then reverses valve so that shot is expressed into mould(s).
Inventor: ATTILO GIUSEPPE
IPC: B29C45/54
Filed: 1992-11-04
Abstract: One or more closed casting moulds are filled by the intrusion of measured quantities of plasticised polymer material, and of contaminated recycled thermoplastics in partic. from an intermittently operating extruder/plasticiser with an intermediate pressure-dose reservoir. The recycled material from the extruder etc. is fed into a pressure-dose reservoir through a 2-way valve when a set volume has reached that reservoir through a 2-way valve; when a set volume has reached that reservoir further melt flow is cut off and the feedline to the casting mould is opened; the mould is then filled with the metered quantity of melt under high pressure which flows in at high speed. ADVANTAGE - The process of filling the mould(s) is simple, and the high flow speed means that there is no significant drop in the melt temp. The large volume moulds can be filled from small capacity extruders/plasticisers.

Title: Scanning and sheet feed control for electrostatic copier - by sheet position sensing and sheet-size related processing to prevent reverse charging of imaging drum, toner waste and contamination
Inventor: OH SOO-HWAN
IPC: G03G15/32
Filed: 1993-02-18
Abstract: To prevent reverse polarity charging of the imaging drum (107) the copy sheet feed (109) is commenced and then energisation of the charging unit (104), position sensor (111) and light source (105). The image transfer unit (106) is energised coincident with the arrival of the copy sheet front edge. When the position sensor (111) is de-activated the exit of the copy sheet rear edge is signalled. A time interval dependent on copy sheet size is determined to allow the sheet to clear the image transfer stage (106). The latter is switched off, the image (103) fixed and the charging unit (104) de-energised. ADVANTAGE - Prevents unnecessary scanning duration e.g. for small dimension work which wastes toner and contaminates processing. Prevents reduction in service life when processing irregularly sized copy paper.
