Abstract: Title SUSPENDED PANEL CEILING HAVING IMPACT   ABSORBENT PANEL RETAINING CLIP ASSEMBLIES     Abstract of the Disclosure Panels resting in a suspended grid are rendered abuse-resistant by mounting two-piece retaining clips atop the runners in the grid.  The clip assemblies comprise a torsional/ flexural spring mated with a clinch fastener.  The spring is a piece of bent music wire having a central U-shaped segment, two opposing legs angling outwardly and downwardly from the upright arms of the U to a level below the cross member of the U.  The clinch fastener is a piece of flat spring steel bent into the shape of a U, the bight of the U being a channel connecting two straps, each of which has a keeper at its distal end which turns inward and upward into the space between the two straps.  The cross member of the spring fits into the channel of the clinch fastener and the unit is snapped onto the bead atop a grid runner so that the cross member is interposed between the bead and the channel.  The retaining clip assemblies may be installed before or after the panels are installed in the grid or the panels and clip assemblies may be installed sequentially.  The legs of the spring bear down on the panels and the spring absorbs the impact of a ball or other object thrown upward at the ceiling.

If a Swiss style yogurt is to be produced, the inoculated mixture is cooled, pumped through a pressure valve to obtain a smooth texture, blended with low calorie fruit preserves, packaged in suitable con-tainers and refrigerated to stop fermentation.  For a Western style yogurt, the inoculated mixture is added to containers containing low calorie fruit preserves and cooled to stop fermentation.

Abstract: ON-BOARD AUTOMOTIVE METHANE COMPRESSOR                 ABSTRACT OF THE DISCLOSURE        A gaseous fuel system for a vehicle including an on-board compressor for recharging an associated pressure storage tank.  The compressor and tank are mounted on the vehicle as a structural unit whereby the tank shields the compressor and high pressure gas flow circuits therebetween and provides a heat exchanger surface for the compressor.  A regulator in series with a supply line of low pressure gas prevents gas flow when the compressor does not operate to maintain a vacuum in an intervening dispensing line.  An O2 sensor disconnects the compressor motor when the percentage of O2 exceeds a predetermined safe limit.  A bypass circuit allows the tank to be filled from a high pressure supply without operation of the compressor.

Abstract: ABSTRACT OF THE INVENTION         In a system for recording and reproducing digital signals on a magnetic tape using a rotary head, in which the signals are recorded as a series of slanted tracks without guard bands between adjacent slanted tracks, a pilot signal that was recorded during the recording process is used to control the tracking of the playback head.  The pilot signal is recorded at a specific position in a specific pilot signal record region, independent from the region of the track at which the informational signal is recorded and the pilot signal is arranged at a predetermined position or positions being a specified distance from an end of each track in its longitudinal direction and only alternate tracks receive such pilot signal.  When the recorded tracks are reproduced by a rotary playback head having a tracing width that is greater than the width of the track, the pilot signals from the adjacent tracks will be detected and can be compared in level, with the comparison output being used to control the tracking of the rotary playback head.

Abstract: SHALLOW-JUNCTION SEMICONDUCTOR DEVICES            Abstract A shallow-junction semiconductor device is fabricated by initially implanting a neutral species (non-doping impurity) into a surface region of a semiconductor body prior to the introduction of a dopant therein.  This implant serves as a getter for defects and also as a physical barrier.  The thermal diffusivity of subsequently introduced dopant species is thereby significantly reduced. As a result, extremely shallow junctions are realized.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved apparatus and method are disclosed for measuring the dynamic surface tension at a gas-liquid interface by the maximum bubble pressure method.  The gas is bubbled out an orifice tube dipped in the liquid; the maximum pressure in each bubble is a function of the surface tension.  In the invention, the rate of gas flow is raised continually to increase the rate of bubbling at least several fold over a few minutes.  The varying pressure of the bubbling gas is measured con-tinuously by an instantaneous transducer.  Electronic circuits respond to the transducer and provide signals indicative of the maximum bubble pressure and of the rates of bubbling.  A recorder responds to the signals and displays a spectrum of the maximum bubble pressure in units indicative of surface tension as a function of the bubbling rate.  Measurements may be taken over more than a thousand bubbles in each spectrum.  The rise in gas pressure is achieved by passing gas from a source under pressure in series through two flow-restricting capillaries, with an accumulator zone between.
