A technique for providing in-place cleaning of a sealing structure for a rotating shaft in a materials processing apparatus wherein, during a cleaning operation, cleaning liquid is supplied in the form of a plurality of jets thereof from a source thereof to a rotating member having a sealing element, such as an O-ring, positioned about the rotating shaft. The cleaning fluid produced a scrubbing action on critical surfaces of the sealing structure to clean them. A plurality of jets of a drying fluid, such as pressurized air, is then supplied from a source thereof to the critical surfaces to remove excess cleaning liquid and to thoroughly dry such surfaces. The cleaning and drying operation can be activated to take place automatically and in-place using a pre-programmed processor without having to disassemble the sealing structure.

A sound activated lamp arrangement includes a module having a threaded lamp bulb socket at one end and a bulb base at the other end for reception in a lamp socket of a conventional table lamp. A lamp bulb is received in the module socket, and a microphone is provided on the module. Circuitry within the module connects the module socket with the module base to thereby illuminate the lamp bulb in response to the reception of an acoustic signal from a smoke alarm device, burglar alarm, or other type of alarm device by the microphone. A photocell is provided on the module and is connected to the circuitry to sense ambient illumination. The circuitry is adapted such that the bulb is only illuminated when the photocell senses darkness. A push button switch is provided on the module for conventional operation of the lamp. A collar is received on the socket shell of the lamp to prevent operation of the lamp switch thereon. For commercial applications, the module is provided with outwardly projecting lugs which engage the harp structure of the lamp to resist removal of the module from the table lamp.

A smoke alarm activated portable light or lamp for providing emergency illumination in response to an alarm signal from a smoke alarm device includes a frequency selective microphone, several amplifier stages, a peak detector, an isolation or buffer stage, and a power stage comprising a pair of cascaded transistors and a light bulb. The lamp includes a bracket for positioning same in proximity to a smoke alarm and a switch which is closed upon removal of the lamp from the bracket. A power saving circuit includes a photoelectric cell and an amplifier and is operative to saturate or overdrive the first gain stage to override any signal from the microphone whereby the lamp is rendered unresponsive to the smoke alarm signal upon illumination of the photocell by daylight or artificial light.
