Title: Electrical switching device
Inventor: BAER SIEGFRIED DIPL ING
IPC: F16P3/20
Filed: 1985-01-10
Abstract: The switching device according to the invention is used for switching electrical apparatuses, such as lawnmowers, verticutters (scarifiers) or the like. In this case, so-called two-hand operation is used for switching on. A switching part which interrupts a power supply lead can be controlled via a first handle. A safety element which, in its one limit position, holds the switching part in the switched-on position, can be operated via a second handle. In this case, this switched-on position is maintained even in the event of a release movement of the safety element during a first section of its movement path. The safety element can be moved by mechanical or electrical means.

Patent DE-3506717-A1 (DE)
Title: Protective device for motor scythes
Inventor: MAST ARTUR
IPC: A01D75/20
Filed: 1985-02-26
Abstract: The protective device prevents damage to plants when mowing is being carried out round these. This device is used especially for the mowing of plantations, since it prevents the young plants from being cut off. The motor scythe is guided, with the protective device, up to the stem of the plant, round which it then mows in circular fashion, the protective device always bearing against the stem of the plant. Since there is a risk that the plant will thereby be pressed sideways and come into the region of the cutters, the protective device must be set very low for small plants. For larger plants, the protective device can be set higher, thus increasing the cutting capacity. A further advantage for forestry is afforded in that, when mowing is carried out by the motor scythe, the plants can be set in a triangular formation, thus resulting in a 20% higher utilisation of area.

Patent DE-3542194-A1 (DE)
Title: Pressure relief valve
Inventor: GIBAS RICHARD
IPC: F16K31/06
Filed: 1985-11-29
Abstract: A pressure relief valve in which a valve element blocking a relief opening is pressed against the sealing seat of this relief opening by means of the armature of an electromagnet with a predetermined force that determines the response threshold pressure is to be designed in such a way that, while being of compact construction, it requires only a relatively small number of parts which can be produced by simple operations and can be assembled easily and in a small number of operations. However, the essential requirement is that it should be possible to set this pressure relief valve easily, simply and reliably and, if required, also post-manufacture in use, to possibly changed specified threshold pressures, on the one hand providing considerable flexibility in the choice of the operating point and, on the other hand, allowing deviations due to tolerances of the individual parts to be compensated for easily, rapidly and reliably. This object is achieved by the fact that the armature of the electromagnet has, in a longitudinal bore, a pin which can be adjusted in its longitudinal direction, is held in a manner which allows it to be fixed and, via a centrically guided tappet, preloads the valve element, so that, by adjusting the pin, the initial air gap formed between the armature and a pole situated opposite to it - the said air gap determining the force exerted by the magnet - can be adjusted easily and in a simple manner to desired force values and hence threshold pressures.

Title: Method for engaging ground targets by low-flying aircraft or missiles
Inventor: SCHOEFFL RAINER DIPL ING
IPC: F41G9/00
Filed: 1986-06-18
Abstract: A rocket (4) is launched from a low-flying aircraft (1) in the direction of flight. This rocket (4) is constructed such that it follows a curved trajectory (flight path) (5) in a vertical plane. As soon as the rocket flies over the location where it was launched or the target (3) it launches a target-homing munition (7) which thus falls onto the target (3) from a relatively high altitude. In consequence, the possibility exists of operating a target-homing munition, which requires high ejection altitudes, from low-flying aircraft. <IMAGE>

Patent DE-3633153-A1 (DE)
Inventor: BRUEGGEN GERHARD DIPL ING
IPC: G01L5/20
Filed: 1986-09-30
Abstract: The wheels of a vehicle have so-called toe-in or toe-out that gives rise to certain forces in the steering linkage (1) which, although not felt at the steering wheel, cause an insignificant elastic deformation of the steering linkage (10). These forces can be measured by sensors (15). An evaluation circuit (8, 9) eliminates from the measurement values of the sensors (10) the forces due to toe-in or toe-out, allowing the adhesive friction between roadway and tyres to be determined. The adhesive friction can thus be continuously measured during travel, without affecting the movement of the tyres.

Patent DE-3640450-A1 (DE)
Title: Sliding-mesh gear set with a reduced tendency for reverse locking
Inventor: JEAKLE WILLIAM GLENN
IPC: F16H63/30
Filed: 1986-11-27
Abstract: A sliding-mesh gear set comprises a first and a second rotatable gearwheel, one gearwheel being capable of sliding into and out of mesh with the other gearwheel. Each gearwheel has a multiplicity of teeth which can mesh with mating teeth on the other gearwheel. Each tooth has two flanks which extend outwards from a root to a top land, and a front end has two chamfers, each of which extends forwards from the flanks to a front edge. Each tooth is designed in such a way that the tip of its front edge is directed inwards away from the top land, thereby reducing the possibility that the front edges of mating teeth will intersect when one gearwheel slides into mesh with the other gearwheel.
Patent DE-3643911-A1 (DE)
Inventor: GSCHWEND HANS
IPC: F16B13/04
Filed: 1986-12-22
Abstract: An expansion dowel assembly includes a sleeve-like support bearing incorporating load engagement surfaces, and annular disks displaceably held on the support bearing by a tension member for displacement between a radially inwardly displaced position and a radially outwardly displaced position. The annular disks are formed of a spring-like material. The tension member clamps the disks in the radially inwardly displaced position in the form of a hollow cone. When the clamping force on the disks is removed, because of their spring-like characteristic, they move into the radially outwardly displaced position flattened out from the hollow cone configuration. A load can be applied to the support bearing at the load engagement surfaces.

Title: Screw (bolt) nut
Inventor: METZLER WILHELM MATHAEUS
IPC: F16B37/04
Filed: 1987-03-13
Abstract: Whenever two or more workpieces are to be connected to one another such that they can carry loads and be flexurally rigid - and can be dismantled again - this can only be advantageously carried out using the screw nut. Further considerations have resulted in it being possible to produce a screw nut with any number of threaded connections, in dependence on structural requirements. For example, for a corner connection in a furniture framework, a table or a transporting box. It also remains to be seen as to whether the German Railway pallet or Europa pallet can be manufactured considerably more easily with the aid of the screw nut. This may be of particular interest for air freight. <IMAGE>
