摘要： 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.

摘要： A digital synthesizer is disclosed for generating complex waveforms of seted multiple frequencies and selected phases in the time domain. A plurality of independent frequency sources each produces square waves at its selected fundamental frequency and at frequencies which are integral multiples, such as twice, four times and eight times, that of the fundamental. A sampling clock whose frequency is at least the highest frequency produced by any frequency source, multiplied by the number of fundamentals used, provides a signal to a binary counter whose output is connected to a line decoder or multiplexer which multiplexes each frequency source's signals on a time-share basis via a system of AND and OR gates. The signal produced by the OR gates is provided to address a memory device which contains a predetermined waveform in a look-up table. The signal produced by the memory device is therefore the multiplexed combination of the signals that would have been produced therefrom had each frequency source alone been applied to address the memory. The complex waveform produced by the memory is provided to a plurality of serial in-parallel out shift registers whose outputs are applied to a plurality of digital-to-analog converters each producing identical waveforms time-delayed with respect to each other.

摘要： A cardiac lead for transmitting electric current to the heart and/or sensing and monitoring electrical activity of the heart has an elongated electrical conductor connected to a head. An electrode mounted on the head comprises a helical wire adapted to be turned into heart tissue. The helical wire is coated with platinum black particles which decrease electrical losses at the electrode-tissue interface. A plug impregnated with a drug located within the head is in contact with the helical wire and platinum black particles thereon. The drug migrates from the plug to the active outer end section of the electrode.

摘要： 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.
