Title: Pneumatic-mechanical tool-clamping system for hollow work spindles carried in rolling bearings
IPC: B23B31/06
Filed: 1988-02-18
Granted: 1989-07-13
Abstract: The invention relates to a pneumatic-mechanical tool-clamping system for hollow work spindles carried in rolling bearings, with provision for automatic tool change, the collet being pneumatically released and mechanically tightened. In this arrangement, the back-up force for the release force, by means of a differential cylinder which is axially displaceable in a ball box and secured against rotation, is passed into the hollow work spindle via a sleeve in such a way that the rolling bearings remain unaffected by it, the hollow work spindle being given a fluid column which encourages a uniform temperature distribution. The release force is transmitted by the fluid column between a rear pressure piston and a front pressure piston in the hollow work spindle to the collet, the closing force being transmitted by a rotating tension wire of the smallest possible cross-section from the rear pressure piston, which can be acted upon by tension springs, to the front pressure piston and to the collet. The fluid column advantageously has as high a heat capacity as possible and/or as low a specific weight as possible.

Title: Sensor for determining angular velocity
IPC: G01C19/56
Filed: 1988-07-23
Granted: 1990-02-01
Abstract: In a sensor (10) for determining angular velocity (<- omega ), a disc (11) is moved at a high rotational speed (<- omega s). If an angular velocity (<- omega ) acts on the disc (11), the disc (11) is deformed on the basis of the Coriolis force (Fc), at least in the edge regions. This deformation of the disc (11) can be detected using optical, magnetic or capacitive means, and is thus a measure of the angular velocity (<- omega ). The sensor (10) has a particularly simple design and a relatively low weight. <IMAGE>

Title: Method for the impulse compaction of moulding sand
IPC: B22C15/28
Filed: 1988-08-22
Granted: 1989-12-21
Abstract: In the moulding method according to the invention, the compressed air blown onto the rear side in a pulsed manner or pressurised gases produced by explosion to compact the moulding sand are extracted with a short delay through the pattern and the pattern plate and the mould is then recompacted mechanically while the vacuum is maintained. The briefly delayed removal and extraction of the gases prevents them from escaping prematurely through thinner areas of the mould and allows the gas pressure on the rear side of the mould required to compact even deep inner or outer mould agglomerations to be achieved.
Patent DE-4005510-C1 (DE)
IPC: B08B9/04
Filed: 1990-02-21
Granted: 1991-05-29
Abstract: Described herein is a device for cleaning a sewer of a kind which, under the action of the flowing sewage, is carried along the sewer by the sewage with a velocity less than the average velocity of sewage flow and which comprises a hollow cleaning ball immersing into the sewage and rolling on the bed or ceiling of the sewer. The outer surface of the cleaning ball has protrusions, the outer surface of the protrusions lie on an imaginary spherical surface. For adapting the effective weight of the cleaning ball to different levels of sewage in the sewer, several water through holes are distributed on the spherical wall of the cleaning ball which open into a sewage space within the hollow cleaning ball at a wall surface on which filth guiding ribs are. The filth guiding ribs end close to the openings of the water through holes.

Title: Allocation recognition system for component of one group in another group - uses bidirectional data flow and codes each component of second group by formation of characteristic electrical connection between selected contacts
IPC: H03M11/20
Filed: 1991-07-10
Granted: 1992-09-24
Abstract: The device described has been designed for recognising the allocation of one package (2) from a first group to one (1j) of a number m of packages (11,...1m) of a second group, where packages of the second group have a characteristic electrical coding (K1,...Km) for each package, obtainable through a number n of terminal contacts (A1,...An) by means of binary switching logic, and the packages of the first group each have an evaluating unit (3) for detecting this coding through a corresponding number of decoder lines (D1,...Dn). The codings consist of a different combination of electrical connections of the terminal contacts with one another, while the decoder lines are set out for a bidirectional information flow. The evaluating unit, for decoding purposes, detects the presence or absence of an electrical connection between each possible pair (Ai,Ak;1 less than equal to i less than k less than or equal to n) of terminal contacts. USE/ADVANTAGE - For printed circuit boards. Greatest possible number of coded components. Can be recognised using binary logic and least possible number of connecting lines.

Title: Device for steering a vehicle with controlled tracking
Inventor: FRANKE UWE DR ING
IPC: B60W30/00
Filed: 1993-09-27
Granted: 1994-09-15
Abstract: In known devices for controlling steering, either switching takes place between a manual and automatic mode, the driver having no direct means of intervention in automatic mode, or the control prescribes a steering torque in addition to that applied by the driver which is intended to indicate the correct course to the driver. In addition to a vehicle position-detection device (1) and a steering control device (4) which acts on a steering angle adjustment device (9), the new device contains a preselectable limiter for limiting the steering angle adjustment required by the control and a means for superimposing a steering angle adjustment requested by the control on a steering angle adjustment requested by the driver, the steering angle adjustment device setting the steering angle in accordance with this superimposition means. In this way, relatively small steering movements are handled by the control while the driver simultaneously retains his possibility of intervening for larger steering movements, e.g. for changing lane and for avoidance manoeuvres. To be used for example for steering passenger cars. <IMAGE>

Title: Instrument for monitoring the mains voltage supply of electrical loads
Inventor: GIMMY MANFRED
IPC: H01R31/06
Filed: 1993-11-19
Granted: 1995-04-20
Abstract: When the mains plug is pulled out, known monitoring devices trigger, via actuation elements in a special plug socket, a signalling device which is powered by the mains. Devices which also reliably indicate mains failure are very expensive. In order to make it possible to operate any instruments with monitoring at each normal plug-socket mains, a circuit for monitoring the mains voltage and for indicating its absence is arranged in a known adapter plug. For reliable monitoring of the electrical load and for simple handling, the mains plug of the load is mechanically retained in the socket of the adapter plug, so that it is possible to separate the load from the mains only by pulling out together with the adapter plug which produces a signal. The monitoring instrument guarantees very reliable handling even when used by uninstructed individuals. <IMAGE>
