Title: Structural element, in particular wall element
Inventor: HERING PETER ING GRAD
IPC: E04C2/34
Filed: 1981-08-14
Abstract: In the case of a structural element (10) which comprises two mutually parallel, planar panels (12, 14) and spacers (16) connecting said panels, the panels (12, 14) have, on their inner side, in each case cross-sectionally T-shaped, arcuate grooves (34 to 36) in which the bar ends (22, 24), which are widened in the manner of plates, are held. In the case of spacers (16) following one after the other in a horizontal direction, the grooves (34 to 36) extend alternately in opposite directions. The resulting connection avoids a parallel displacement of the panels (12, 14) with respect to one another, and in the grooves (34 to 36) there is formed, after concrete has been poured into the structural element (10), in each case a hook-like continuation of the concrete core, which continuation promotes a fixed connection of the panels (12, 14) to the concrete core. Descriptions are likewise given of production process, which can be carried out continuously, for structural elements of this type and an apparatus for carrying out the process. <IMAGE>

Patent DE-3134248-A1 (DE)
Title: Lockable cabin, in particular for spraying paints, coatings and the like
Inventor: SAUER WERNER
IPC: B05B16/60
Filed: 1981-08-29
Abstract: To save heating energy for heating the cabin air, in particular in the case of a spraying cabin having a large air volume, that is to say a comparatively large, in particular high, cabin, during the spraying pauses or before commencement of spraying, during preparation of the material to be sprayed for the spraying operation, the ventilation can be switched over from exhaust air to recirculating air. In exhaust-air operation, which is known per se, air is fed via a fresh-air duct whereas the air loaded with paint mist and the like is conducted to the outside via the exhaust-air duct. The switch-over from fresh-air operation to recirculating-air operation and vice versa is carried out via a first pivot flap, which is coupled in terms of movement to a second pivot flap. In the cabin interior there is disposed a lifting platform and a rest mount for at least one spray gun. When the latter is picked up, this effects a locking of the cabin door, an adjustment of the pivot flaps, that is to say switch-over from recirculating-air operation to exhaust-air operation and fresh-air operation and the enabling of a central coating-material and paint feed. The switch-over when the spray gun is put down is preferably carried out via a delay device, however at least the blocking of the coating-material feed takes place immediately.

Title: Fuel injection system
Inventor: WISSMANN MICHAEL DIPL ING
IPC: F02M69/22
Filed: 1981-10-17
Abstract: A fuel injection system is proposed for the fuel supply of a mixture-compressing, spark-ignition internal combustion engine. The fuel injection system upstream of a throttle valve (24) in the air intake pipe (23) comprises a choke valve (32), which is displaced in the direction of flow as a function of the quantity of air drawn in and thereby displaces a piston slide valve (30) connected to it as a movable valve element of a metering valve (1, 41, 42). Downstream of the metering valve (1) the metered fuel passes by way of a fuel line (6, 54) into a control chamber (7) of a control valve (8), which is separated from a control chamber (10) by a diaphragm (9). The pressure in the control chamber (10) can be controlled as a function of operating variables of the internal combustion engine. From the control chamber (7) the metered fuel passes by way of a valve seat (11) to an injection valve (12), through which the fuel can be injected upstream of the throttle valve (24) coaxially with the air intake pipe (23). <IMAGE>

Title: Wheel support trolley
Inventor: MURILLO HERNANDO
IPC: B66F7/24
Filed: 1981-11-06
Abstract: The invention relates to a small, compact collapsible three-wheeled support trolley which can be placed under a flat or defective tyre of a vehicle so that the vehicle can be driven to a garage. The support trolley has a folding-over ramp which lies flat on the ground whilst the rear wheels are raised to a certain extent so that the support trolley cannot move out of its position when the defective tyre is moved onto the support trolley. If the ramp turns upwards into the locking or holding position behind the tyre, the rear wheels are lowered again onto the ground. At the same time, a device attached to the ramp causes a stop element in the front area of the support trolley to turn upwards into a position supporting the tyre. After the tyre is standing on a support it can then move neither forwards nor backwards in relation to the support trolley.
