Abstract: ABSTRACT     A power tong includes a frame and a pipe-gripping mechanism associated with a throat at one end of the frame.          Power is transmitted to the pipe-gripping mechanism from a power unit comprising a multiple speed motor through a drive train.          The pipe-gripping mechanism cooperates with the throat to receive a pipe section to be rotated and includes a partial ring rotatably mounted within the frame and having an opening which may be aligned with the throat.  The ring may be rotated in either direction by the power unit.  Mounted on the tong is a die carrier which is rotatable relative to the ring.  Link members are pivotally mounted on the die carrier and include dies positioned to grip the external surface of the pipe section.          The link members are arranged to cooperate with specially designed cam surfaces on the ring so that, when the ring is rotated relative to the die carrier, the dies moved into engagement with the pipe section.  After the movable dies have engaged the pipe section further relative movement between the ring and the die carrier is prevented and the pipe section is therefore rotated to make up or break apart the threaded joint of the pipe.          The drive mechanism comprises a multiple speed motor capable of rotating the partial ring in either direction.  The motor includes a gear shaft which drives a pinion gear.  A pair of pinion idler gears are positioned on either side of the pinion gear and are rotated thereby.  A pair of rotary idler gears are driven by the pinion idler gears, and the rotary idler gears each drive a rotary gear associated with the partial ring.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates generally to improvements in fluid flow control systems for parenteral administration of medical liquids. Positive pressure infusion pumps of the syringe type are known.  How-ever, since a portion of each operating cycle with such syringe type pumps is concerned with filling the syringe through an intake line, rather than delivering fluid to the patient in a pumping mode, the accuracy of such devices tends to fall off, particularly at very high flow rates, where the fill stroke period is of significantly large duration relative to the pump stroke period.  The present invention overcomes this deficiency by providing a system for fluid flow control utilizing a syringe pump operated by a stepping motor to repetitively fill and empty a syringe cartridge over a plurality of operational cycles of successive fill stroke and pump stroke periods.  The stepping motor is driven by electrical drive pulses from a digital pulse generation and control system.  Means are provided for maintaining a proportional relationship between the preselected pumping rate and the actual fluid flow pumping rate over each com-plete cycle of successive fill and pump strokes, the motor drive pulse frequency during each pump stroke is automatically increase to compensate for the time slot during each fill stroke.  A detection device is provided which responds to the detection of fluid flow in the intake line during a pump stroke.

Abstract: RCA 68690 Div. A       ABSTRACT        COLOR-PICTURE/MULTICHANNEL-SOUND         PLAYBACK APPARATUS     Color picture information is recorded on a video disc together with multiple channels of sound information (e.g., a pair of stereo sound signal components).  Each audio signal to be recorded modulates the frequency of a respectively different sound carrier over a respectively different low frequency deviation range.  Picture carrier waves are frequency modulated in accordance with composite color video signals, including a luminance component and a chrominance component.  The duty cycle of the modulated picture carrier waves is varied in accordance with the sum of the respective frequency modulated sound carriers to form a recording signal.  The sound carrier deviation ranges lie below (but near) the band occupied by the chrominance component.     A disc record is developed with a pattern of depressed and non-depressed regions in its groove bottom representative of the recording signal.  Playback apparatus recovers from the disc record a playback signal of the general form of the recording signal. Respective bandpass filters, with pass-bands centered about the respective sound carrier deviation ranges, select playback signal portions for application to respective sound carrier FM demodulators.  Additional filter, with passband encompassing picture carrier deviation range and first order sideband therefor, supplies input to picture carrier FM demodulator.  Video signal processing circuits, responsive to output of picture carrier FM demdoulator, include respective comb filters for selectively passing respective luminance and chrominance components.
