摘要： A tube cleaning apparatus for tubes and pipes installed in power plant and similar industrial equipment utilizes a rotating brush assembly fitted to one end of a rotary cable encased in a protective casing and driven at its other end in clockwise and counterclockwise rotation by a reversible motor. The invention provides a drive unit fitted with a plurality of drive rollers for engaging the protective casing and propelling the casing, cable and brush assembly at a high rate of speed into and out of each tube being cleaned. A control system for the drive unit enables the operator to manipulate the reversible motor by issuing pulses to actuate switches controlling on/off and direction of rotation of the motor. An arresting device provides for stopping forward progress of the brush assembly as it reaches the end of each tube being cleaned.

摘要： An electronic postage meter employs a membrane switch mechanism. The postage meter is of the type having a mechanism for printing postage and accounting circuits for accounting for postage printed by the printing mechanism. A membrane switch is coupled between the printing mechanism and accounting circuits to provide print wheel setting information to the accounting circuits. The membrane switch mechanism may in one embodiment include a plurality of switch contacts and a plurality of switch contact actuating structures to activate different ones of the switch contacts. The membrane switch is mounted such that different ones of the plurality of the actuating structure activates a predetermined one of the plurality of switch contacts depending upon the position of the print wheels.
