Patent DE-3734337-A1 (DE)
Title: Heat exchanger
Inventor: BROST VIKTOR DIPL ING
IPC: F28D1/053
Filed: 1987-10-10
Abstract: A heat exchanger, for example a radiator for an internal combustion engine for a vehicle, has a heat exchanger grid which is inserted between two tube plates (sheets) and consists in accordance with the required cooling effect of a specific number of flat tubes and folded lamellae assigned to the latter. Provided on the mutually opposite outsides of the heat exchanger grid is one lateral part each into which there are impressed (stamped) unidirectional transverse reinforcing fins (seams) of specific height which bear against the outer tubes of the heat exchanger grid and can be soldered to the latter. By using lateral parts provided with transverse reinforcing fins, it is possible in a simple way to employ the present heat exchanger grid of a heat exchanger designed for a width B0 to provide, while maintaining the grid dimension of the tube pitch and with virtually the same cooling effect, a heat exchanger which has a width B1 which is reduced by comparison therewith. For this purpose, instead of the lateral parts and the outer lamellae of the wider heat exchanger use is made of the lateral parts provided with the transverse reinforcing fins. The height of these fins is in line with the width B1.

Patent DE-3738679-A1 (DE)
Inventor: BICKFORD JOHN
IPC: G01L5/24
Filed: 1987-11-13
Abstract: A fluid powered torque wrench 10 is automatically operated until a preset torque has been delivered to a fastening. As shown, the preset torque is inputted to a computer 114 from a keyboard 116. Computer 114 communicates with a microprocessor 30 which closes a relay 110 to advance the wrench. Fluid pressure is monitored by a transducer 26 and the data is fed from the microprocessor 30 to the computer 114 which determines therefrom whether the preset torque has been reached or whether the wrench has merely completed its advance stroke. By operating relays 110 and 112 the computer retracts the wrench, advances it once more and repeats the cycle until the preset value is reached. The system provides a direct read-out of torque on a display 25A or 118. Also described is a method comprising determining from the pressure data, the nut factor of the fastening being tightened in order to enable determination of the torque needed to obtain a desired preload. <IMAGE>

Title: Process for producing at least one thin-film magnetic head
Inventor: DIEPERS HEINRICH DR
IPC: G11B5/31
Filed: 1988-05-02
Abstract: The process is to be used to produce on a non-magnetic substrate a thin-film magnetic head which includes a conductive element carrying the magnetic flux and having two magnet legs, which have pole faces lying in a common plane. In this case, first of all a preproduct of the magnetic head is formed with end pieces of its magnet legs protruding beyond the plane of the pole faces. These end pieces are then removed from the underside of the preproduct up to the plane of the pole faces. The material removal is to be carried out with high accuracy. It is therefore provided according to the invention that an at most 2  mu m thick zone (25) of the end pieces (8, 9), immediately adjoining the plane (23) of the pole faces (F1, F2), is machined away by means of polishing by ion bombardment (28). <IMAGE>
Patent DE-3820042-A1 (DE)
Title: Positive displacement pump
Inventor: HOFMANN FRANK DIPL ING
IPC: F04B43/107
Filed: 1988-06-13
Abstract: The invention relates to a positive displacement pump in which during the pressure stroke the displacement of a mechanically driven piston which can be displaced in a cylinder is transmitted hydraulically with the aid of a liquid to a flexible displacer which is clamped in a hermetically tight fashion, and aims at providing a simple positive displacement pump having a flexible displacer which is actuated during the pressure stroke via a hydraulic receiver. Because of its simple design, this pump is not only cost effective but can be miniaturised more easily than the previously known pumps with hydraulic receiver while still retaining a high operational reliability. The aim of the invention is for the flexible displacer (13), which is constructed as a bellows, and the hydraulic piston (11), which has a larger effective cross-section (A1) than the effective cross-section (A2) of the displacer, to be returned for this purpose during the suction stroke into the upper reversing position solely by a force acting on the displacer (Fig. 1). <IMAGE>
Patent DE-3832487-A1 (DE)
Inventor: RUSSELL RICHARD MICHAEL DR PHI
IPC: B29D30/00
Filed: 1988-09-24
Abstract: In a pneumatic vehicle tyre, the rubber inner layer is formed from an adhesive rubber and styrene-butadiene copolymers, wherein the content of styrene, which is bound in the molecule, in the blended mixture is at least 15 parts by weight per hundred parts of rubber. A low gas-permeability and sufficient mechanical strength are hereby attainable for the rubber inner layer. The production of the pneumatic vehicle tyres, which have an initially cross-linked or partially cross- linked rubber mixture for the inner layer, is possible because the tyre is vulcanised without a bellows. The costs for the raw materials and for the production method can therefore be considerably reduced.

Title: Two-stroke engine with scavenging and supercharging
Inventor: EICKMANN KARL
IPC: F02B25/04
Filed: 1988-11-04
Abstract: An internal combustion engine is demonstrated, which is intended to overcome the disadvantages of the conventional two-stroke engine and to increase its power for a given weight and for given dimensions. This is achieved in that a scavenging device and a supercharging device are assigned to the cylinder, which act in succession. Shortly before the end of the expansion stroke, the piston first exposes the exhaust ports. Then the scavenging device opens, scavenges the exhaust gases from the cylinder and fills it with fresh air. The scavenging device then closes and the supercharging device opens, in order to fill the cylinder with charge air, highly compressed in comparison to the scavenging air, the lines for the scavenging air and the charge air remaining permanently spatially separated from one another throughout these processes. The supercharging device then also closes and the actual compression ensues in the cylinder. The separation of the supercharging from the scavenging according to the invention gives the engine the cleanliness and precision of the four-stroke engine. Charge air losses or losses of fuel fractions in the charge air, which still frequently occur in the two-stroke engine, are thereby avoided and the two-stroke engine is thereby suitable for the efficient use, for example, of turbochargers, which leads to a considerable increase of the engine power without resulting in the losses often still present in two-stroke engines. The turbocharged two-stroke engine of the invention then functions with practically just as high efficiencies as ... Original abstract incomplete.

Title: Method for making powder-forged components, in particular a connecting rod with divided connecting rod big end
Inventor: WEBER MANFRED DR
IPC: B22F5/00
Filed: 1989-01-25
Abstract: Powder-forged components which consist of two individual parts are made into their final form starting from a one-part preform by pressing from powder, sintering, forging, cooling and separating into their individual parts. The object of the invention is to simplify this method considerably and at the same time achieve accurate-fitting production of the individual parts. This object is achieved according to the invention in that the preform is provided, before sintering, at the separating point between two individual parts with at least one scribed notch which, between sintering and forging, receives a protective layer, in particular oxide layer, and is closed during forging to the final form, in that at least one splitting-course notch is additionally provided in the region of the desired separating plane and at a distance from the scribed notch, and in that the component is separated into its individual parts after cooling, by fracturing. The method according to the invention can be used, for example, for making a connecting rod with separated connecting rod big end, in which method, after cooling of the connecting rod, the holes for the connecting rod bolts are made in the connecting rod big end, connecting rod bolts and connecting rod nuts are loosely fitted in the holes and subsequently the separating surface is produced in the separating plane of the connecting rod big end. <IMAGE>
