Patent DE-2807635-A1 (DE)
Inventor: SCHULER HANSJOERG
IPC: B01J49/85
Filed: 1978-02-22
Abstract: The device has a contact mechanism water meter as signal emitter, which comprises an impeller (3) which is driven by the water flowing through and which triggers emission of a signal via a gear. After an adjustable number of signals, the regeneration of an exchanger resin or an inoculation is initiated. In order to make possible an adaptation to different water hardnesses without having to associate the water meter or the contact mechanism with variable gears or electronic or electrical addition systems, a rotatable valve (11) with a bore (12) for varying the inflow cross-section is provided in the inflow (4) to the impeller (3) of the water meter. This valve allows an infinite variation of the ratio between the speed of rotation of the impeller (3) and the flow rate within a sufficiently wide range. <IMAGE>

Title: High pressure pick-up for weapons applications - has stick-free piston with elastic grooved seal and with annular recess in housing near piston end
Inventor: BROSA ERICH
IPC: G01L19/00
Filed: 1979-04-18
Abstract: The high pressure pick-up is uncomplicated, and has no membrane and operates reliably in weapons applications, giving a linear hysteresis -free response. It is a piston device whose play or space between the piston (2) and its housing is such that the piston thickening caused by transverse contraction and the housing narrowing caused by external essure and screw tightening do not lead to the piston sticking. This is ensured by use of a special easily interchangeable seal (13) for an annular recess (7) in the housing near the piston end. Dust rubbed off the seal is collected along with other matter in a chamber behind a constriction (10). The seal is of elastic material with an annular groove (12) whose cross-section is V-shaped and which is coated with a ceramic layer (17).

Patent DE-2924971-A1 (DE)
Title: Desalination of solutions by reverse osmosis - includes dividing supply into two streams at different pressure using flow work exchangers
Inventor: POHL MANFRED DR ING
IPC: B01D61/06
Filed: 1979-06-21
Abstract: The concentrate under pressure leaving a plant for the sepn. of salts from a soln. by reverse osmosis, is fed to a chamber or into one end of a double reservoir assembly; the reservoirs being spheroid, ellipsoid or double-conical rotation bodies. These have geometrically similar sepg. membranes or are membraneless pressure vessels, with or without fillings or inbuilt structures. At the same time a vol. of soln. from the other end of the double reservoir goes to a pump. This compresses the vol. of soln. to the input pressure by overcoming a relatively small difference between its pressure and that of the reverse osmosis plant. Parallel to this operation, the salt soln. to be sepd. flows into a corresp. chamber section of a second or further similar membrane double reservoir, so that from its other side practically pressureless concentrate is drained. This is the concentrate which is fed into this other chamber in the previous one of the corresp. operational phases under pressure and with the corresp. transporting energy. Used for the prodn. of drinking and/or industrial water from brackish or seawater. The process, using conventional pumps without detenting machines for the concentrate, makes considerable savings of energy possible.

Title: Ball bearing pitting prevention system - uses annular piston providing axial preloads when stationary or with races turning at same speed
Inventor: LAUDENBACH HORST
IPC: F16C19/52
Filed: 1979-07-14
Abstract: The system prevents pitting of ball- or roller-bearings, particularly in motor vehicle gearboxes. When the bearing is stationary an axial pre-load is applied. There is no axial pre- loading when its two races are moving in relation to each other, but a preload is applied when they are both turning at the same speed. The pre-loading can be applied by an annular piston (11), or a number of individual pistons spaced round the periphery. The system can be used in a change-speed gearbox. Oil pressure can be used to exert the pre-loading.

Abstract: 1. Radio network with a master station (Leit) and with substations as well as with two or more transmit-receive installations (small relay stations) (SE1 ... SEn), the transmitters of which transmit on the same or nearly the same frequency and the receivers of which receive a second frequency, feed the demodulated reception signal as modulation to the transmitter and key the transmitter in dependence on the reception voltage, characterised thereby, that a control circuit (St) in the transmit-receive installations (SE1 ... SEn) controls the transmission power in such a manner that a great transmission power is radiated in the case of high reception level and a small transmission power is radiated in the case of low reception level, that furthermore adjustable damping members (D) are built into the connecting lines from the transmitter (S) to the frequency separating filter (W), by which damping members (D) a damping inversely proportional to the path damping, determined by measurements, in direction of the master station (Leit) is set in such a manner that in the case of full transmission power, an about equally great reception voltage from all relay stations arises in the receiver of the master station (Leit) (Fig. 1).
