Abstract: 1,140,180. Measuring fluid flow. SOC. D'INSTRUMENTATION SCHLUMBERGER. 29 Dec., 1967 [5 Jan., 1967], No. 59198/67. Heading G4H. [Also in Division G1] In the measurement of the rate of flow of a fluid, at least two turbine flowmeters, which generate cyclic signals of frequency proportional to the fluid flow rate, are arranged in parallel or series in the fluid pipe, their outputs being compared and an alarm or indicator being operated if the difference exceeds a preset amount dependent on the flow rate, whereby the faulty operation of one of the flowmeters may be indicated. Interference signals picked up between the turbine and its output terminals are removed by providing two pickups 16, 18, Figs. 1, 2 (former not shown), e.g. sensing the passage of magnets 14, 15 on the ends of the turbine blades. Alternatively the pick-ups may be of inductive, photoelectric or radioactive type. The outputs from the pick-ups, 90 degrees out of phase, are fed via amplifiers 20, 22 and pulse shapers 24, 26 to an EXCLUSIVE OR circuit 32 whose output is free of interference. In operation two such arrangements are used, the outputs from the EXCLUSIVE OR circuits 32, 32<SP>1</SP>, being fed via frequency meters 36, 38 to a differential circuit 40 whose output is connected to an alarm 42 and indicator 44. The output from circuit 40 may also be used to automatically open a by-pass pipe and close the pipe in which the faulty flow meter is arranged so that it may be easily repaired. The outputs from the circuits 32, 32<SP>1</SP> may also be combined in an OR circuit and fed to a total volume indicator 34. The arrangement may be extended to more than two flowmeters.

Title: Vehicle Washing Equipment
IPC: B60S3/06
Filed: 1978-09-16
Abstract: Vehicle washing equipment comprises a cleaning brush on a swing arm. The arm is biased towards a rest position and is deflected from this position by a vehicle so that the brush follows the contours of the vehicle.
