Patent DE-3133288-A1 (DE)
Title: Fuel injection system on an internal combustion engine
Inventor: SCHROLL RUDOLF DIPL ING
IPC: F02M47/00
Filed: 1981-08-22
Abstract: In a fuel injection system on an internal combustion engine with one injection valve (1) per engine cylinder, the valve needle (2) of which can be moved in the opening direction by the fuel fed in against the force of a closing spring (3), a buffer reservoir (6) for receiving the quantity of fuel to be injected is arranged upstream of the injection valve (1). The buffer reservoir (6) is in turn connected to a fuel feed pump (8) and can be continuously supplied with fuel from this, the pressure of which fuel is lower than the opening pressure of the injection valve (1). The fuel can be fed from the buffer reservoir (6) to the injection valve (1) by means of a pressure-transmitting piston (9), pneumatically operatable in timed sequence with the engine. The line between the buffer reservoir (6) and the injection valve (1) can be opened and closed in timed sequence with the engine by means of a pilot valve (11) and can be relieved of pressure following closure of the pilot valve (11) by means of a pressure relief valve (12) connected downstream of the pilot valve in the direction of flow. The buffer reservoir (6) is formed by a pump cylinder (15), in which the pressure-transmitting piston (9) functions with its delivery piston (16), to which a larger diameter piston (18), functioning in a pressure cylinder (17), is connected, which latter piston defines a pneumatic pressure chamber (17) to the rear. Pressure can be admitted to the latter from an air vessel (26) by way of a two-way reversing valve (36) and also relieved again by this, in each case in timed sequence with the engine. <IMAGE>

Title: Change-speed gearbox having a plurality of layshafts
Inventor: EHRLENSPIEL KLAUS PROF DR
IPC: F16H57/023
Filed: 1981-11-10
Abstract: The invention describes a change-speed gearbox having a plurality of layshafts, in which load compensation is provided in order to compensate the components of the tooth force which arise under load with helical or spur toothing. In order to achieve this in the case of rigidly supported layshafts, the input shaft is supported in an elastically flexible manner. However, it is also possible, in the case of a rigidly supported input shaft, for elastic support for the layshafts to be provided. This elastic support is achieved by the fact that the corresponding bearing eye is connected to the gearbox housing via a thin elastic web. The bearing eye can be connected to the housing by a single web or by two webs and it is possible for the web to be produced integrally with the housing or as a separate component with the possibility for fixing the web in the housing. <IMAGE>

Title: Switching device for telephone sets
Inventor: SCHINKE HANS-JOACHIM
IPC: H04M1/08
Filed: 1981-11-25
Abstract: The switching device has a multiplicity of contact springs (2) in a common carrier part (1) and control strips (6) which are guided in the carrier part in such a way that they can be moved in a straight line and which are allocated to these contact springs. The control strips are combined to form three separate runner units (10, 11, 12). In each case, they have a different drive connection with an actuation lever (13) mounted on the carrier or with an additional operating element of the telephone set (22), are coupled to one another partially in a direction-dependent drive connection and are partially restricted in their freedom of movement by mechanical elements, e.g. energy stores (21, 30), locking switching mechanisms (27, 28, 29). The switching device serves as a telephone hook switch with additional functions and enables the actuation of specific contact groups, in part optionally, by means of different operating elements (19, 22), inter alia to set up a telephone connection while the handset remains on-hook. <IMAGE>
Patent DE-3149986-A1 (DE)
Title: Test method and apparatus for determining characteristic fracture values of instantaneously stressed materials or structural elements
Inventor: HAHN ORTWIN PROF DR ING
IPC: G01N3/30
Filed: 1981-12-17
Abstract: In order to be able to assess the tensile impact behaviour of materials or structural elements, impact tests are carried out at high deformation velocities and the fracture energy is determined. This is done, however, using correction curves because the kinetic energy of the partial mass which flies off during fracture has also to be taken into account. Inaccuracies are inevitable. As a result of the invention, the impact energy and the kinetic energy contained in the mass thrown off are determined by sensors experimentally in the same test. The total impact energy expended is then automatically corrected to give the actual fracture energy. The true fracture energy is then indicated immediately or further evaluated or processed by an automatic measurement evaluation and/or processing system. This makes it possible to obtain precise characteristic values for the toughness behaviour of materials and structural elements under instantaneous stress. The specific conditions of each test are correctly taken into account.

Title: Method of washing a flow cell
Inventor: NAGAI YAWARA
IPC: B01L99/00
Filed: 1982-05-11
Abstract: In order to wash the flow cell of an automatic analyser for chemical analyses, a test solution is sucked into a reaction vessel at a suction station by means of a suction nozzle in the flow cell and the test solution is measured photometrically. A wash liquid, for example water, is delivered to the reaction vessel and then sucked through the suction nozzle and the flow cell. In this way, the reaction vessel, the suction nozzle and the flow cell can be effectively washed with a large quantity of wash liquid. The wash liquid is delivered and sucked in every time a reaction vessel reaches the suction station, regardless of whether it contains test solution or not. Any contamination between consecutive test solutions is consequently effectively avoided and the inside wall of the flow cell is always kept in a wet state.

Title: Spring-accumulator cylinder, in particular a brake cylinder
Inventor: PRESSMAR MANFRED
IPC: F16J15/16
Filed: 1982-10-28
Abstract: The invention discloses a brake cylinder having a spring-accumulator space (14) and a ventilation device (18) for the latter. To protect the ventilation device (18) from spray, the device has at least one valve-like closure device (20), within a ventilation channel (19), and a filter (21) situated on the outside. The filter is arranged in front of the channel (19). The closure device (20) is seated in the spring-accumulator space (14) and closes off the channel (19) in the case of a pressure equilibrium while, in the case of a negative or positive pressure in the spring-accumulator space (14), it automatically frees the channel (19) to allow pressure compensation. The filter comprises an insert ring (22) in an annular groove (23) of the bushing (16) seated against the base (15). The closure device (20) comprises two U or V rings (28, 29), each of which shuts off associated annular spaces (32 and 31 respectively) transversely, which spaces are formed by subdivision of the annular space (26) by means of a sleeve (30) and are connected to one another via openings (33) in the sleeve. The sealing lip (34) of one U or V ring (28) can lift off, allowing flow in one direction, and the sealing lip (35) of the U or V ring (29) can lift off in the other, opposite, direction. Impurities, water and moisture are kept out of the spring-accumulator space (14) and there is essentially always a pressure equilibrium between the spring-accumulator space (14) and atmosphere (Fig. 2). <IMAGE>

Title: Cutter shield for driving the gate roads of an underground working face or the like
Inventor: STUCKMANN DIETER
IPC: E21D23/00
Filed: 1982-11-05
Abstract: The cutter shield according to the invention serves to drive gate roads of underground mining operations. Its special feature consists in the fact that at least some of its driving cutters are designed to be multi-piece in such a way that individual cutter sections can be removed from the driving cutters to form a face opening. A corresponding face opening can be produced at the supporting frame of the cutter shield by parts of the supporting frame being removed, which parts are arranged so as to be easily detachable. The cutter-shield design according to the invention therefore enables the face opening to be created at any peripheral point of the cutter shield by taking out and inserting the removable cutter parts and supporting-frame parts.

Title: Composite support system
Inventor: HEINTZMANN PETER DIPL ING
IPC: E21D11/15
Filed: 1982-11-26
Abstract: A composite support system of non-yielding anchors, wire-mesh sections and pressure plates is known. In underground mining operations, this composite support system has proved successful where no convergence or only slight convergence occurs and the rock is less friable. According to the invention, a composite support system for underground operating points at considerable risk of convergence comprises yielding anchors 4 functionally merged with wire-mesh sections 5 and channel-section segments 6 extending in the peripheral direction of the roadway 1. The section segments 6 overlap one another at the ends. In the event of convergence they can thereby follow the reduction in size of the roadway 1. Nevertheless, they firmly hold the layers of surrounding rock together. <IMAGE>
