Title: Device for adjusting the height of a working surface
Inventor: KRITSKE VICTOR JOSEPH
IPC: B23Q1/00
Filed: 1981-06-26
Abstract: A device for changing the height of a working surface with two essentially rectangular telescopic tubes guided inside one another, has a horizontal support at the upper end of the inner telescopic tube and, on the bottom plate of the outer telescopic tube, a rotary actuator which sets a vertical spindle within the inner telescopic tube in rotation. Engaging in the spindle is a spindle nut which is held in a rotationally fixed manner and is seated on the lower end of a thrust sleeve fixedly connected to the inner telescopic tube. Rotary actuator and spindle are connected to one another by a ratchet drive with torque limitation. The supporting and guiding of the inner telescopic tube in the outer telescopic tube takes place via stabiliser roller arrangements on the inner telescopic tube which are displaceably guided and spring-loaded in obliquely running slots in bearing blocks in such a manner that they brace the inner telescopic tube in a frictional manner with respect to the outer when the rotary actuator is at a standstill. This bracing is released by the adjustment force, transmitted by the rotary actuator to the thrust sleeve, for the adjusting process and automatically comes into effect again at the end of the adjusting process.

Title: Piston pump for operating fluids driven by a combustion engine
Inventor: ZIMMERMANN WOLFGANG PROF DIPL
IPC: F04B35/00
Filed: 1982-01-22
Abstract: The most important characteristic of the piston pump for operating fluids driven by an internal combustion engine lies in the fact that the power piston of the internal combustion engine is at the same time also the working piston for liquid and gaseous media. Prime mover and machine are accommodated in a common housing. In the case of a multiple-cylinder machine the individual pistons, which serve for the pumping of liquids, especially hydraulic oil, and gases, especially air, are frictionally connected by way of a crankshaft. An optional flywheel bridges the working strokes occurring between the power strokes of the internal combustion engine. Where sufficiently lubricating hydraulic oil is being pumped, a separate lubrication and cooling system is dispensed with.

IPC: A63B69/12
Filed: 1982-01-28
Abstract: An auxiliary appliance has been developed as a movable grip bar system as a substitute for a grip bar which cannot be installed in a swimming pool with an overflow channel. Said appliance consists of an inherently stable, stainless tubular frame which consists in triangular form of two upper belts as grip rods and, for reasons of reinforcement, of a lower belt which is connected by appropriate diagonals to the two upper belts. The appliance is placed on either side onto the bead of the overflow channel of a swimming pool by means of two or more plastic rollers, and guided by the latter in the running direction on the longitudinal sides of the pool. The appliance thus offers the possibility of a two-sided grip rod system for versatile water exercises which can be moved to any desired point of a swimming pool and is situated a few centimetres above the water surface. The appliance has a weight of approx. 75 kg, and when not required is lifted out of the bead by two persons using grips provided on the two supports and hung on the wall on the narrow side of the indoor swimming pool. <IMAGE>

IPC: B23Q3/06
Filed: 1982-06-12
Abstract: The invention relates to a workpiece exchanging or replacement device for machine tools and aims to improve the useful effect of the workpiece exchanging device. The workpieces are positioned and arranged and clamped on or removed from each workpiece clamping pallet at a workpiece replacement station that is provided externally of the machine tool, in order subsequently to be conveyed from a transfer bed to a workpiece clamping pallet exchanging station where they are pushed onto a workpiece table of the machine tool, arranged and positioned and are clamped thereon ready for machining. The workpiece clamping pallet comprises a base plate in which hydraulic cylinders are fully inserted. Each cylinder comprises a vertically movable piston below the head surface of the base plate. The piston may carry a clamping member which is detachably secured thereto in order thereby to transmit a clamping force from the piston to the clamping member. The base plate also comprises an oil circulation system in order to apply hydraulic pressure to each of the cylinders. Furthermore, a leakproof and liquid tight, reversible shut-off valve is provided to maintain the oil pressure in the hydraulic cylinder and in the oil circulation system of the threaded plate, in order to permit the oil circulation system to be closed so that it is also possible to transfer the workpiece clamping pallet with the oil hose separated and to continue with the machining work without having to fill up with hydraulic oil. In order to guarantee safety in the rare occurrence of oil leaks, means preventing a drop in oil pressure and means detecting a drop in oil pressure are also provided. <IMAGE>

Title: Method and device for regulating a water jet from a nozzle
Inventor: NAPIERSKI REINHARD
IPC: B05B17/08
Filed: 1982-08-25
Abstract: The method of regulating a water jet from a nozzle is intended, for example, for a fountain. The constantly discharging water flow from the pump (16) is partly diverted via the slot (13) into the pressure chamber (5) and partly discharges there from the driving nozzles (7). This sets the rotor (1) in rotation, and the discharge opening (8) and the slot (13) are thus rotated relative to one another, and the constant water flow therefore divides into two water jets constantly changing in opposite directions. <IMAGE>

Patent DE-3235804-A1 (DE)
Inventor: URBANSKI WILFRIED
IPC: G10L19/02
Filed: 1982-09-28
Abstract: A method and a circuit for narrow band voice transmission is proposed which leads to a particularly large reduction of the required transmission bandwidth. The method emerges from a voice frequency band (VF) which is divided up into three frequency bands, namely a lower frequency band (FBU), a centre frequency band (FBM) and an upper frequency band (FBO). The lower frequency band characterises the vowels of the voice, the centre frequency band the lower frequency range of the consonants and the upper frequency band the upper frequency range of the consonants. The centre frequency range is excluded from transmission. The envelope curve frequency band (FBO') is derived from the upper frequency band and is converted into a frequency range which is adjacent to the lower frequency band. In this way, in the case of analogue signal transmission, instead of the original voice frequency band (VF), only a frequency band which is smaller by approximately two thirds is transmitted. <IMAGE>
