Abstract

1307893 Control or indicating device in a filter PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 4 March 1970 10411/70 Heading BID A pressure-operated switch 2 is connected to a tank 1 containing unfiltered machine-tool coolant, to monitor the head thereof, by a duct 13 into which an auxilliary pump delivers air continuously to keep aperture 14 in the tank wall from clogging. The filter may be of the moving band type described in Specification 1,128,061, switch 2 serving to start the bandmoving motor when the head of liquid in tank 1 rises in consequence of clogging of the section of the filter band in use, and also to stop the downstream pump and relieve the suction in proper sequence. The invention is also applicable to a gravity flow filter, and switch 2 might control a backwashing action or close a valve to cut off the liquid supply when a filter clogs. Alternatively switch 2 could operate a warning lamp to indicate the need for a control function by a human operator.
