Title: Water energy converter with hollow rotor - which has spiral channels terminating in diametrically opposed nozzles and deflectors
Inventor: PROESCHEL ERICH
IPC: F03G7/10
Filed: 1979-06-05
Abstract: A water energy converter operates with a hollow rotor in the form of a cylinder or disc (10) featuring spiral channels (16, 17). These run in the direction of motion to impart a centrifugal force to water which is thrust to the diametrically opposed nozzles (18, 19). The latter exhibits a smaller cross section than that of the spiral channel for directing the two water jets onto deflectors (20, 21). The reaction of the jets impinging the deflectors give rise to a torque transmitted by the rotor to a shaft (11) for maintaining the rotor movement. The housing surrounding the rotor has a catchment channel for returning the ejected water back to the rotor through the open end of rotor boss (15). The initial acceleration of the rotor is ensured by a drive engaged with a clutch.
Patent DE-2927051-A1 (DE)
Title: Protective circuit for analog sensor multiplexer number - has photon-couplers contg. LED's which are connected to analogue sensors, and which produce light that is intercepted by photo-transistor
Inventor: KOVACS LASZLO
IPC: G08C15/06
Filed: 1979-07-04
Abstract: The circuit operates in conjunction with a multiplexer containing a number of low-impedance analog sensors. The circuit detects and indicates the occurrence of an open circuit in any one of the sensors, which each include a piston-coupler with a LED. The light emitted by each diode is intercepted by a photo-transistor connected through resistors of high value across the related sensor input line to define a network generating a small offset-current. Should an open-circuit occur, the offset current charges the capacitor of a noise-rejection filter connected to each sensor to a high level, with a polarity opposed to the normal polarity established there across by the sensor. As a consequence, the digital value produced by an A=D converter is well outside the valid range, and provides an indication of the abnormal condition.

Abstract: PCT No. PCT/EP80/00042 Sec. 371 Date Mar. 4, 1981 Sec. 102(e) Date Mar. 4, 1981 PCT Filed Jul. 4, 1980 PCT Pub. No. WO81/00044 PCT Pub. Date Jan. 22, 1981.The present invention discloses an adjustable office chair in which the backrest may be adjusted in relation to the seat carrier. This adjustment is realized by means of an actuating lever and a clamping bolt arrangement which allows a linkage system to vary the position of the backrest in relationship to the seat. Once a desired relationship between the two parts is realized, the actuating lever is released and the linkage system is locked into a fixed position. This arrangement is realized by providing a spring system which displaces a clamp bolt in its longitudinal direction relative to the parts to be immobilized. The actuating lever, when activated, acts on a thrust bearing of the clamp bolt and displaces the clamp bolt into the release position.

Title: Device for developing photo material having a cylindrical drum which is driven to rotate
Inventor: PETSCHING HELMUT
IPC: G03D13/04
Filed: 1981-01-23
Abstract: In a device for developing photo material having a cylindrical drum which accommodates the photo material and is driven to rotate, the drum axis is arranged essentially horizontally in the working position, which is effective for treatment. Feed and discharge lines for the treating liquid of the development process are provided at the drum ends. For the purpose of quickly discharging the treating liquid, the drum axis is inclined in order that the drum end provided with the outlet occupies a lower position than the other drum end. So as to carry this out simply and in a space-saving way, the drum end which can be raised and lowered is received in an eccentrically mounted multi-part gear unit which serves to transmit the rotary movement of the drum. The eccentric member of the gear unit can be locked in one of two defined rotary positions which correspond to the working position and emptying position of the drum. If the eccentric member is released, the drum is switched between these two positions.   <IMAGE>
