Patent DE-3540500-A1 (DE)
Title: Hydrodynamic pump installation
Inventor: MUELLER WALTER
IPC: F03B17/06
Filed: 1985-11-15
Abstract: A tubular pile anchored in the river bed has a double-acting pump made of worn-out car tyres attached to it by means of frame clamps. The pump is driven via a loop of rope by a drive sleeve which is mounted between the frame clamps. Fastened to the journals of the drive sleeve there is a drive fork to which a long drive lever is linked. At its end, one or more drive rudders are mounted which are steered independently. The drive rudder is immersed in the river flow in a floating manner and is laterally deflected thereby owing to the oblique incidence. The angle of attack is determined by a limiting chain fastened to the drive lever. Owing to the drive lever swinging back and forth, wide flows can be utilised. A plurality of such installations can be combined into an installation working in parallel. In such an arrangement, the ends of the drive levers are linked to one another by means of a transverse beam. Many drive rudders can be mounted on the transverse beam, which makes it possible to utilise even weak flows.

Title: Circuit arrangement for ultrasonic flowmeters
Inventor: STARK REINHARD DIPL ING
IPC: G01F1/66
Filed: 1986-09-30
Abstract: A circuit arrangement for ultrasonic flowmeters based on the phase-difference principle or the lambda-locked-loop principle. The ultrasonic flowmeter is formed by a pair of interdigital converters which define a measuring zone running obliquely with respect to the direction of flow of a liquid running through a measuring tube, are fitted on the wall of the measuring tube and have a so-called finger structure, namely a respectively transmitting interdigital converter and a respectively receiving interdigital converter. For its excitation, the transmitting interdigital converter is alternately fed, via a first or second group of electrodes, electric pulses by means of a phase-reversal device, supplied by a voltage-controlled generator. A phase detector is provided, to which the output signal of the generator is fed via a first input as a reference signal and to which a reception signal is fed via a second input from the receiving interdigital converter, and which emits a control signal to the generator via an output. Instead of a fixed default value of the transmission signal, an electric signal corresponding to the converter deflection is picked up directly at the interdigital converter (IDW) acting as the transmitting converter. This electric signal is picked up as a reference value in the form of a reference signal (R) for the reception signal (E) by the reference signal amplifier (RV). <IMAGE>

Patent DE-3703128-A1 (DE)
Title: Monitoring method and device for dynamically loaded rubber articles
Inventor: SPITZ WOLFGANG DIPL ING
IPC: B60C23/04
Filed: 1987-02-03
Abstract: The invention relates to a method for monitoring status data of dynamically loaded articles, essentially made of rubber or rubber-like materials, using a measuring element, transmitter, receiver, indicator element and an electric voltage source, the measuring element and the transmitter being located in a component to which the rubber article to be monitored is assigned and is rotatable to an unlimited degree with respect to another component which bears the receiver and the indicator element. It can be used in particular for monitoring motor vehicle tyres and belt drives. In order to reduce the energy consumption of the transmitter, it is proposed that the status data be transmitted with relatively long pauses between the transmission times and the radio carrier frequency of transmitter and receiver be considerably higher than the switching frequency of the transmitter. For the frequent case that not only the transmitter but also the measuring element is consuming current, it is proposed in a supplementary fashion that the measurement of the status variables to be monitored should also take place with relatively long pauses between the measurements, and that measurement and transmission should be synchronised. During this process, the receiver remains preferably ready to receive without interruption.
