Title: Motor vehicle brake rate indicator - has brake pedal and level to actuate series of switches for lamps operated in sequence
Inventor: SCHEMMEL GUENTER DR
IPC: B60Q1/44
Filed: 1976-08-18
Abstract: The brake rate indicator eliminates subjective evaluation of the vehicle deceleration, the display offering a warning signal to other users of the road.

Title: Hot gas filter backflushing system - with timer sealing off filter outlets as air blasts are applied
Inventor: HOELTER HEINZ
IPC: B01D46/00
Filed: 1977-06-14
Abstract: A backflushing device for hot gas filters has power cylinders on the filter casing which are actuated by a timer to press sealing discs with compressed air blast tubes against the clean gas outlet of the bag filters in a certain cycle. The air supply to the blast tubes is controlled by the same timer. In the filtering time of the cycle, compression springs keep the sealing discs at an adequate distance from the filter outlets. This is a simple way of overcoming the backflushing problem and to seal the filters for best blasting efficiency, when no elastomer seals are permitted, like in hot gas filters. The bag filters are arranged in the filter casing with an inlet for hot gases and a worm conveyor for the discharge of dust. Normally, compression springs keep the sealing discs of the clean gas outlets of the filter bags. When a timer admits compressed air at certain intervals to the pipes, power cylinders press the sealing discs with the distributor pipe and the air blast tubes against the bag filter outlets and air blasts through the tubes flake off any dust deposits from the bag filters.

Title: Automatic borehole direction stabiliser - with valves and pistons in control housing inside direction measuring tube
Inventor: GRAEFER ALBRECHT DR ING
IPC: E21B7/10

Abstract: An automatic stabiliser for deep well drilling operations consists of a direction measuring tube which runs on rolling friction bearings on the drill tube near the drill bit. A control housing near the bit end is fitted with hydraulic pistons on the periphery. Normally closed poppet valves open the access for the pressurised drilling fluid to the pistons, if the direction measuring tube indicates any deviation from a straight line. The piston concerned then moves the drill bit until the hole is straight. Straight boreholes are ensured, for 100 m and more in the horizontal direction and for 1000 m and more fordown holes. The appts. is equally suitable for non-coring or coring operations, including those with core recovery by rope.

Filed: 1977-11-12
Abstract: The load-bearing elements in the building roof are designed as beams (1). A load-bearing cover (3) is located above said beams (1) and followed by a thermally insulating layer (8). It is made possible to walk on said insulation layer (8) by means of a retaining and adhesive layer (11) which can bear loads. A vapour barrier (6) is fitted on the thermally insulating layer (8) consisting of plastic with closed pores. The beams (1) consist of an iron profile, concrete, wood or plastic and the load-bearing cover (3) consists of a profiled metal sheet, lightweight concrete or plastic. The insulation layer (8) comprises panel-type boards which have overlapping rebates (9). The retaining and adhesive layer (11) consists of sheet metal, e.g. aluminium sheet metal, or plastic. The boards (8) are laid with a spacing all around them in order to ensure free movement in the event of temperature changes. The retaining and adhesive layer (11) borders the upper, offset part of the boards (8) and covers them. A sealing skin (18) is adhesively bonded on the retaining and adhesive layer (11). This roof for halls and the like is watertight and thermally insulated and, despite this, is of a much simpler design than known roofs of the same quality. In addition, it is inexpensive to produce and easy to mount. <IMAGE>
