Abstract

1470773 Timing operation of machines PLESSEY CO Ltd 19 June 1974 [22 June 1973] 29877/73 Heading G1J [Also in Division H2] An electrolytic cell for measuring and indicating the aggregate operating time of electrical apparatus is mounted in the housing of an electrical plug or socket by which power is supplied to the apparatus. The plug or socket may include a switch for the electrical supply. The cell may be in series or parallel with the apparatus, and preferably is arranged to light a neon indicator when a predetermined aggregate time is reached, e.g. to indicate that routine servicing of the apparatus is due. The cell may be pre-set by feeding it with a current in the direction opposite to that applying in use for predetermined time.
