Title: Combined wall support frame/falsework system
Inventor: MAYER GERHARD
IPC: E04G21/18
Filed: 1984-04-06
Abstract: A combined wall support frame/falsework system for the cost-effective erection of walls using artificial masonry blocks. The wall support frame, which, corresponding to the progression of work involved in wall-building, can be increased in height in each case by one layer or else to an infinite extent, serves simultaneously as a stop for alignment purposes and for the height and as a guide for producing window and door reveals. This integration of various functions ensures that walls are built in a cost-effective manner and also has the object of restricting the physical exertions of the worker, by virtue of an optimum operating height and the use of a gripping hoist.

Title: Filter element for separating out solid particles from gaseous or liquid media
Inventor: HERDING WALTER
IPC: B01D46/52
Filed: 1984-04-07
Abstract: The known filters, which operate by the principle of depth filtration, have the disadvantage that their filter resistance increases with the duration of use. On the basis of a filter using the surface filtration principle, a continuing efficiency is ensured in that the foreign particles are deposited on a slidable, non-hygroscopic, temperature-stable layer (5) and do not penetrate into the interior of the filter element (3). The filter element can be cleaned in a simple manner in the reverse-pulse process after appropriate fouling. <IMAGE>

Title: Vehicle brake system
Inventor: GRAUEL INGOLF DIPL ING
IPC: B60T13/68
Filed: 1984-06-29
Abstract: The vehicle brake system (2') functioning with pressure medium is designed, for example, for a vehicle with a front wheel axle and a rear wheel axle and has two electrically controllable service brake circuits (I' and II') with an electrical brake pressure reference value transmitter (4) adjustable by means of a service brake pedal (3) and a control unit (5') and brake pressure sensors (18, 20), which serve as actual value transmitters. The service brake circuit (II') comprises a pressure accumulator (10), a solenoid brake pressure build-up and brake pressure reduction valve (74), two wheel brake cylinders (23, 24) and the brake pressure sensor (20). In the event of differences between actual and reference value, the valve (74) is controlled so as to reduce the differences. Between the valve (74) and the wheel brake cylinders (23, 24) a leakage drain valve (65') is connected, which is electrically closed as soon as braking is commenced. If the service brake pedal (3) is not operated it connects the wheel brake cylinders (23, 24) to the atmosphere so that unwanted brake pressure cannot be generated owing to the leakage of the valve (74).

Title: Push-button switch which is extrusion coated with foam material
Inventor: LEITNER GEORG DIPL ING
IPC: H01H13/08
Filed: 1984-11-10
Abstract: A push-button switch which is extrusion coated with foam material has two boards 2, 7 which run parallel to one another and between which an elastic supporting device is inserted. External pressure can be exerted manually, via an operating surface 10, on the foam material layer which covers the first board 7, by means of which pressure contact surfaces 3, 4 can be made to make contact, which contact surfaces 3, 4 are located on the second board. The push-button switch is in this case, in particular, injection moulded into the foam material sheath of a steering-wheel spoke. In order in this case to prevent the switching gap being closed even as a result of the pressure which occurs when the push-button switch is extrusion coated with foam, and remaining closed, the supporting device has at least one dome-shaped snap-spring element 6 which is seated with its open edge on the second board 2 and whose dome rests on the first board. The open edge in this case rests on a conductor train 3, while a second conductor train is provided underneath the dome of the snap- spring element, which dome snaps through when manual force is applied. Thus, if pressure is applied onto the operating surface 10, the dome-shaped snap element over the first board 7 is caused to snap over, and an associated contact gap is closed. A horn circuit, for example, can be closed via the contact gap. <IMAGE>
Patent DE-3441968-A1 (DE)
Title: Article-fixer clamping device and machining process
Inventor: LOOMER WESTON R
IPC: B23Q7/14
Filed: 1984-11-16
Abstract: Workpiece-fixing devices are clamped in a clamping pallet in such a way that the first fixing device assumes a predetermined position in the pallet and with respect to the second fixing device. A base plate is arranged in a sandwich-like manner between annular components, in the central opening of which a fixing pin is inserted and locked by an arresting ring. Arresting recesses in the arresting ring are seated on arresting balls. A cross pin passes perpendicularly with respect to the axis of rotation through the fixing pin. A workpiece base has spaced-apart openings with opposite grooves. When the cross pins are aligned with the grooves, the base can be set by means of the fixing pins. A turning of the cross pins over arresting ring and arresting balls locks the base and the surface of the clamping pallet. One opening in the base interacts by a snug fit with a fixing pin in order to achieve an exact positioning of the clamping pallet. The other opening allows for variations in part-dimensions. Workpiece positioning devices on a machining station interact with the fixing devices for the exact positioning of the workpiece.

Title: Protective padding for a restraint belt
Inventor: GOLDMANN ERHARD
IPC: B60R22/00
Filed: 1985-01-21
Abstract: The invention relates to an additional device on known restraint belts for seats in motor vehicles, aircraft etc., which people put on for safety reasons and because of legislation. These restraint belts are produced from a non-stretchable textile material and are fastened on the seat or the vehicle body to be elastic only via the so-called automatic retractor device. In order to make the already installed belt parts which bear firmly against the body soft and absorbent in the region of the heart, the chest and the shoulders, a protective padding having known padding dimensions is proposed, which can additionally be attached to these points which are close to the body by means of press studs or touch-and-close fasteners as well as zips. These cushions of protective padding improve a person's willingness to put on the belt and avoid pressure on a person's body in the region of the sensitive organs and limbs when travelling and in possible thrust situations in order to absorb in a protective manner recoil forces when braking and in accidents.
