Inventor: EDELHOFF GUSTAV-DIETER
IPC: B65F3/02
Filed: 1991-01-24
Abstract: The invention relates to a refuse vehicle (1) with a lifting and dumping device for picking up and emptying refuse containers into a receiving chute of a collecting receptacle, said lifting and dumping device consisting of at least one lift arm (2), connected to the refuse vehicle so as to be pivotable, and of at least one fork having a receiving claw (36) connected in articulated fashion to said lift arm, said fork being pivotable by means of pressure-medium actuated piston-cylinder units (6, 7) with associated control means. In order to achieve the object of providing a refuse vehicle of this kind in which it is ensured that refuse containers to which it is attached by means of its lifting and dumping device can be emptied in such a manner that said refuse containers are tipped only when above the receiving chute to such an extent that the refuse falls out of their openings, the lift arm (2) and the receiving claw (36) are provided with phase-angle sensors, which generate signals corresponding to the respective pivot angle between the lift arm and the refuse vehicle and the receiving claw and the lift arm. These signals are fed to a computer which controls the control valves of the pressure-medium actuated piston-cylinder units according to choice in such a manner that the latter carry a refuse container attached to the receiving claw or the like essentially horizontally over a predetermined part of the lift path and pivot said refuse container only in the final range of the lift path for emptying into the receiving chute. <IMAGE>

Title: Hybrid vacuum deposition - uses ions of one component and droplets of another to give thick layer on rough surfaces
Inventor: ROTHER BERND DR RER NAT
IPC: C23C4/137
Filed: 1991-02-09
Abstract: To deposit bonded and thick layers on to a surface, with a rough surface structure such as compound fibre materials as insulation to be soldered with components or to be bonded to other components, the process uses vaporising, ion deposition and vacuum plasma spraying. One component of the deposition material is ionised to more than 10%, to give a mean directed ion speed of more than 10 power 3 m/s. They act together with another component of the deposition material in the form of droplets or chips with a mean natural speed of more than 30 m/s, with a particle dia. of up to 50 microns to form 10-90 mass% of the layer material. The two components are deposited simultaneously on the underlay, where the neutral and ionised components are generated at the same time as the accelerated macroscopic components of the deposition material are generated. ADVANTAGE - The layer material is deposited in vacuum, with a min. number of process stages, in a simple appts

Title: Hinged cover for oil wells - has pipe with flap held in open position to allow easy flow of oil and which can be easily closed to extinguish burning well
IPC: E21B33/02
Filed: 1991-03-18
Abstract: Hinged cover has a pipe in which the flap is held in the open position by a screw so that it cannot be moved by oil flowing past. When this pipe has been securely connected to a pipe carrying oil, the flap can be released by unscrewing the screw and can then be turned about an axis pin to fit into the passage outlet. USE/ADVANTAGE - The cover can be used to close off an oil well that has been burning. After the fire has been extinguished the cover bipe is welded into the delivery pipe from the well. When the securing screw has been released, a spring pushed the flap out into the oil stream, which presses it into the passage outlet so that the flow is stopped.

Title: Thrust nozzle for rocket drive with variable expansion ratio - uses ring-shaped device, and circumferential injection of gaseous liquid medium to detach nozzle flow
Inventor: SIMON MICHAEL
IPC: F02K9/82
Filed: 1991-05-14
Abstract: The thrust nozzle has variable expansion ratio. It is arranged for max. expansion ratio. Devices located in a ring-shape on the circumference of the lower expansion section cause the nozzle to detach the nozzle flow, and prevent further expansion. Switching or removal of the devices, reverses the detachment of the nozzle flow, and frees the next largest expansion ratio. Detachment is by injection of e.g. gases or easily gasified fluids. The injection medium may be separate, or may consist of the fuels carried, pref. non-oxidyzing fuels. Alternately, it may consist of ambient air, which is taken in through circumferential apertures. These are closed automatically by non-return valves, when the ambient pressure drops, resp. relative internal nozzle pressure rises. The medium may also be formed by pressure gases of the turbopump. ADVANTAGE - Optimum performance with lowest risk and expenditure.
Patent DE-4118148-A1 (DE)
Inventor: JERFY FRANZ
IPC: H03K17/732
Filed: 1991-06-03
Abstract: Two bipolar transistors (T1 and T2) having complementary sequences of zones are interconnected in such a way that the collector of the pnp-transistor (T1) is connected to the base of the npn-transistor (T2), whereas the collector of the npn-transistor is connected to the base of the pnp-transistor. A diode (DD), preferably a Schottky diode, prevents the saturation of both transistors at the same time in their interconnected state. This arrangement is particularly suitable for quickly switching electric currents and voltages, in particular in capacitive and ohmic loads, or for quickly reversing the charge of capacitances. Several variants that allow the circuit to be easily controlled, as well as composite structures such as half-bridge and bridge circuits for bipolar switching applications, are developed from the basic circuit.

A second magnetic valve (15) has its input connected to the control line (4.2;4.3) of the setting transmitter and regulator (4). Its outputs are connected to one of the drive lines of the pneumatic drive as well to a pressure release. The coil (15.1) of the second magnetic valve lies in a holding current circuit with at least one off switch and is changed over in the same way as the valve (14). The venting of the magnetic valves (14,15) is carried out via silencers (19.1;19.2). ADVANTAGE - Setting of pneumatic or hydraulic servo valves with required backup achieved with one valve and drive.

Title: Road wheel for tracked vehicles with rolling bearing - uses plate springs for automatic bearing clearance adjustment
Inventor: LAUSE HEINZ
IPC: B62D55/15
Filed: 1992-08-21
Abstract: Necessary adjustment of axial clearance of taper roller bearings is via plate springs. Due to this, bearings are always adjusted to optimum degree under varying operational conditions, e.g. play-free without being overloaded. The plate springs (5) are used in conjunction with tension sleeves (7), which determine position and height of pretension. The remaining spring travel after installation is 0,1 to 0,2 mm. The springs are centred on the shaft (2), and mounted, so that the inner faces of the OD support themselves on the inner ring of the of the bearing. The tension sleeves also fasten end pieces (4) to the shaft, to act as abutments. USE/ADVANTAGE - The use of plate springs with flat spring characteristics permits mfr. with greater tolerances. Operationally caused changes in bearing distances are compensated, without placing any undue load on the wheel bearings and increase axial clearance.
