Title: Auxiliary high-speed gearing for drilling and milling machines and suchlike machine tools
Inventor: KRUMM JUERGEN
IPC: B23Q11/12
Filed: 1984-02-01
Abstract: An auxiliary high-speed gearing for drilling and milling machines and suchlike machine tools has a gear case (6) which can be connected to the spindle housing (2) of the machine tool in such a way as to be fixed in terms of rotation. Rotatably mounted in the gear case (6) is a drive shank (7) which has a tapered shank (8) fitting into a tapered location bore (3) of the machine-tool spindle (1). A bearing bush (11) with a tool-holding spindle (12) rotatably mounted therein is flange mounted on the front end of the drive shank (7). The bearing bush (11) has a tapered location bore (13) coaxial to the drive shank (7) for the tapered shank (14) of a drilling or milling tool. A planetary gear unit is provided between drive shank (7) and tool-holding spindle (12). The bearing bush (11) is surrounded by a cylindrical cooling jacket (44) to avoid greater heating. The cooling jacket (44) is connected to the gear case (6) and is supplied with coolant from the spindle housing (2). <IMAGE>

Title: Resectoscope
Inventor: NAKADA AKIO
IPC: A61B18/00
Filed: 1985-01-09
Abstract: A resectoscope has an electrode (29) by means of which an affected part is removed by cauterization or fulguration on excitation with high-frequency current. A sliding body (21) in which there is formed an electrode-receiving opening (30), in which an energy connection (32) is firmly attached, is displaceable along the resectoscope. The near end of the electrode is inserted in the electrode-receiving opening and fastened on the connection. An elastic seal, whose inner diameter is smaller than the outer diameter of an insulating coating (31) with which the electrode is provided, is provided on the inlet of the electrode-receiving opening. As a result, penetration of water droplets or blood into the electrode-receiving opening (30) is prevented. <IMAGE>

Patent DE-3504531-A1 (DE)
Title: Releasing device for safety ski bindings
Inventor: JANISCH PAUL DIPL ING
IPC: A63C9/088
Filed: 1985-02-11
Abstract: Safety ski bindings are released if the releasing forces exceed the release values set. Since forces of equal magnitude rarely act on a pair of skis, often only one binding is released. In the case of a fall, the risk of injury is greater if this is so than if both the bindings are released. After release of an automatic binding, the releasing device according to the invention automatically effects the release of the binding of the other ski. For this purpose, for example the jaws are swivelled upwards about a horizontal axis by a spring system. This release mechanism is locked in the skiing position by an interlock. The interlock is deactivated by means of an electromagnet or electric motor with gear mechanism when the circuit is connected to a battery. This takes place by contacts which are arranged on jaws and automatic heel fittings in such a way that, in the event of a releasing action, they close one of these parts. If in a fall no binding is released, both bindings can be released simultaneously by means of a push button switch. If there is the danger of being buried by an avalanche, this emergency release may save the skier's life.

IPC: F15B13/07
Filed: 1985-04-24
Abstract: In a construction machine, namely in particular an excavator, the working device of this machine is actuated by a number of hydraulic actuating elements. The actuating elements are in each case assigned hydraulic control circuits, each of which has at least one control line which leads to a control input for the assigned actuating element and is connected via a manually actuatable control valve to a source for a hydraulic liquid which is under pressure.

Patent DE-3517828-A1 (DE)
Title: Pump casing
Inventor: RIEL AXEL
IPC: F04D29/42
Filed: 1985-05-17
Abstract: The invention relates to a sheet-metal casing for centrifugal pumps, a box girder being arranged in the region between the intake-side connection and the intake-side casing wall. This ring-shaped box girder ensures that the pipeline forces acting on the intake connection are transferred to the pump casing, without a deformation in the vicinity of the intake connection resulting in the impeller butting against the wall. The rigidity thus achieved in the inlet region permits a resilient design of the casing in the region of the discharge chamber, which enables trouble-free pump operation in spite of pipeline forces acting on the casing.

Title: Internal combustion engine with closable and variable combustion chamber
Inventor: RENNER EWALD DIPL ING
IPC: F02D15/04
Filed: 1985-07-02
Abstract: In the four-stroke induction engine the combustion chamber Vc is designed as a cylinder with light Vc piston, controlled by a spring, cam and gas pressure, displaceable in the cylinder, which piston closes the combustion chamber towards the end of the exhaust stroke and opens it at the end of the induction stroke, thereby obtaining good filling with more than 25% pressure charging and additional power. At partial load the combustion chamber can open only partially in order to generate the same compression as at full load and improve efficiency. Rich fuel mixture can also be drawn in on the back of the Vc piston and when the Vc piston is forced upwards by the compression can be injected as a stratified charge by way of grooves into the combustion chamber, for example in self-ignition engines. The facility is provided for adjustment of the injection point. <IMAGE>

IPC: H01L23/532
Filed: 1986-05-14
Abstract: In pressure-contact switchable semi-conductor elements with a divided contact electrode in the semi-conductor body, improved switching behaviour by means of specific resistors in the current path of the emitter region areas is achieved by the fact that a base metallization (6) is applied to each base region part lying between two emitter region areas; that an insulating layer (7) is appled to each base metallization, extending over the appropriate edge of the two emitter region areas; and, on the insulating layer, is applied a through-type emitter metallization (8) which covers the insulating layer and the free surfaces of the emitter region areas. The superficial parts of the emitter metallization, which are correspondingly located over a base metallization, carry a through-type contact plate (10) made of, for example, molybdenum. The emitter metallization is so dimensioned that the corresponding lateral voltage drop between the contact plate and plane of symmetry of an adjacent section of emitter region exceeds 10 mV during operation with a nominal voltage.

Abstract: The invention relates to a seat mounting with a seat-adjusting means (4) for a vehicle seat (1). Known seat mountings with a seat-adjusting means contain sliding rails or ball-race rails, which are sensitive to dirt and, when there are manufacturing tolerances, can be stiff. According to the invention, there are, in contrast, mounted on the vehicle body (9) fixed connecting points (brackets 10, 11 with axes of rotation 12, 13), which are connected via length-changeable and adjustable adjusting linkages (14, 15, 16) to corresponding, fixed connecting points (brackets 5, 6 with axes of rotation 7, 8) on the seat (1). By changing the length of the adjusting linkages (14, 15, 16), the seat (1) can be adjusted in its longitudinal direction, height and inclination. In a preferred embodiment, electric motors (17, 18, 19) are used for an adjusting means, which motors are controlled via a control unit (20) in accordance with the characteristics stored there. <IMAGE>
