Title: Head restraint for a motor vehicle
Inventor: GRAD PAUL
IPC: B60N2/58
Filed: 1987-10-30
Abstract: The invention relates to a head restraint for a motor vehicle, in particular a framed head restraint, with a fixed inner supporting frame, with a foam part (2) surrounding the supporting frame and with a cover fabric (3) around the foam part (2). In order to fit and fasten the cover fabric (3) there is fitted into the foam part (2) a channel (5) running around the outside. According to the invention, the adjacent fabric edges of the cover fabric (3) are joined by a seam (7) and this seam (7) is pulled into the channel (5) by a surrounding pull cord (8) and held there. Due to the tension which can be applied by the pull cord (8) to the cover fabric (3) tolerances in the cut and in the sewing process are compensated for and the cover fabric (3) is held well and lies smoothly. In addition, the seam (7) disappears in the channel (5) and all that can be seen is a clean surrounding join. <IMAGE>

Title: Device for controlling the additional air for a fuel feed system by way of an intake manifold of an internal combustion engine with four-stroke carburettor engines
Inventor: STYS ANTONI DIPL ING
IPC: F02B75/02
Filed: 1988-03-08
Abstract: The invention relates to a unit, which has been connected to an intake manifold and a camshaft in order to control the additional air to a fuel feed system. The unit, by way of the operation of the camshaft, grades the additional air supply for each intake stroke as long as the exhaust valve and the intake valve are simultaneously open, the ventilation of the cylinder is fed with the weak petrol-air mixture so that the economy of the carburettor and the environmental pollution are improved. The technical solution of the undertaking shows that the unit (4) with the intake manifold (2) is connected by way of a bent shaft (5) (or other method) to the camshaft (6) of the internal combustion engine (1) and the additional air is drawn in through an air filter (3) by way of each cylinder at the start of each intake stroke. The double-sided feed system of the engine is successful because the volumetric efficiency of the cylinder and the power output of the engine is improved by the boosting as a result of the higher than normal velocity of the exhaust gas molecules.

Title: Screen sleeve for rotary screen printing and method for producing a screen sleeve
Inventor: SAUERESSIG JACOB-HEINRICH
IPC: B41C1/14
Filed: 1988-08-11
Abstract: Known screen sleeves consist of pure nickel and are produced in a complex procedure comprising many steps. This leads to high material and production costs. The new screen sleeve is to be more cost-effective. Additionally, a method for its production is to be specified. The new screen sleeve is characterised in that it consists of plastic. As a result, a substantial cost reduction is achieved. For the production method, provision is preferably made for the screen sleeve to be made of plastic by the centrifugal casting method and subsequently to be provided with the desired pattern perforation by means of laser rays. The new method provides a screen sleeve of high quality at low production costs with little outlay. The new screen sleeve is particulary suitable for use in rotary screen printing. <IMAGE>

Title: Contact for electric connections
Inventor: DEHARDE HORST
IPC: H01R13/187
Filed: 1988-08-31
Abstract: Plug connections are used to an increasing extent in switching installations. In this case, the contacts of these plug connections play a significant role, since contact making, the capability for versatile use and the capability for simple production are important.   The invention indicates a contact for electrical connections, in the case of which a contact spring consists of wire which is wound with a number of turns 5 to form a polygonal coil 3 whose polygon tips 6 of turns 5, which are in each case located one behind the other and at a distance from one another, run in a spiral course around the coil axis 8. This polygonal coil is inserted in a socket contact part 2. As a result of the polygonal tips 6 and the turn regions 7, a particularly intimate contact is produced in the form of points between the polygonal tips 6 by a connection of the socket contact part 2 to a pin contact part 1. Such a contact can be used particularly for medium-voltage switching installations. <IMAGE>

Patent DE-3907152-A1 (DE)
Title: Pressure control valve
Inventor: LISKA GEORG
IPC: F16K17/04
Filed: 1989-03-06
Abstract: The invention relates to a simplified pressure control valve which can be set to a large range of pick-up pressures. The invention is to be able to use as few and inexpensive components as possible. The pressure control valve is based on the principle of the so-called tie rod. The valve element employed is a closure member (4) designed in one piece with a bolt (6) and in the form of a countersunk head screw. This screw (4, 5) is drawn sealingly against a valve seat (3) by a spring (8) supported on a screw element (1) and on a nut (7) screwed onto the bolt (6). When the pressure control valve is opened, the closure member (4) "hangs" in the flow and thus assumes a stable position. The pressure control valve therefore works in a manner free from vibrations and without rattling (Fig. 2). <IMAGE>

Title: Tool shank for milling cutters - has regular curvilinear polygonal collar positively engaging with matching bore in spindle nose
Inventor: SCHOENHAAR BRUNKE ING GRAD
IPC: B23B31/00
Filed: 1989-05-19
Abstract: A tool shank (10) for milling cutters, end mills, boring tools, tool holders, etc is produced with a regular curviliear polygonal collar (13) which engages positively with a matching bore in the spindle nose and permits high rotational speeds in the range 10,000 to 100,000 rpm without slipping. Alternatively the drive may be transmitted by a collar having backwards pointing gear formed teeth which engage with corresponding teeth on the end face of the spindle nose. The groove (16) has diametrically opposed holes (17) which can be engaged by the gripper mechanism of an automatic tool changer. The small gap (a) between the flange (15) and spindle nose is witness that the taper shank is properly seated. USE/ADVANTAGE - Tool shank for milling cutter is of balanced design with minimum inertia permitting highest rotational speeds.
