Abstract: PLANAR BOARD AND CARD-ON-BOARD   ELECTRONIC PACKAGE ASSEMBLY ABSTRACT OF THE DISCLOSURE      An electronic package assembly having means for providing direct interconnection for one or more planar electronic circuit boards with a nearly conventional card-on-board circuit package.  Electrical interconnec-tion between the card-on-board package and the planar boards is accomplished with the use of interposer cards that utilize a pin and spring blade contact system and printed circuitry to connect corresponding pins on the planar boards and the card-on-board package.  The mechan-ical advantage necessary to overcome the spring contact force encountered in insertion and extraction of the planar boards is provided by a unique lever arrangement which latches and unlatches the planar boards.

Abstract: ABSTRACT OF THE INVENTION         A combination of magnetics and a special geo-metric environment is employed to distinguish whether an instrument is positioned within a pipe formed of magne-tizable or non-magnetizable material, and is the basis in part, for a method and an apparatus used in controlling picture taking at the bottom of a well bore.  A coil is energized repetitively in a circuit in which the voltage across the coil, or the current that flows through the coil, can be measured.  Whether the coil is in a magnetic or non-magnetic environment is determined by the magnitude of the change in coil voltage or current.

Abstract: ABSTRACT OF THE DISCLOSURE         A thermostatic controller system for a building heating and/or cooling system (furnace) includes a stored program of desired temperatures which are to be attained within the building at predetermined times within a repetitive time cycle, such as a day.  Differing environmental conditions externally of the build-ing result in differing rates of change of temperature within the building upon operation of the furnace.  In order to determine the optimum time to switch the system on to meet the next pro-grammed increased temperature, the furnace is switched on and then off a short period of time later and the temperature change which results in the building as a result of that transient operation is measured.  The time at which the furnace must be switched to attain the next programmed temperature is then determined as a function of the rate of temperature change as determined by the transient switching and the difference between the instantaneous and the future programmed temperature.          Alternatively, the controller may calculate the rate of temper-ature change each time the furnace is turned on for normal building temperature modification and use the last stored value of that rate in the turn-on time calculation.  The system attains an energy efficiency exceeding that of conventional thermostat systems.

Title: Heat-sink imaging method and apparatus for  recording surface topology
Inventor: MCCORMICK-GOODHART MARK H
IPC: A61B5/117

Abstract: A HEAT-SINK IMAGING METHOD AND APPARATUS     FOR RECORDING SURFACE TOPOLOGY                      Abstract of the Disclosure The recording of surface topology is obtained by first bringing the surface into contact with the imaging material-coated side of a dry process dispersion type recording film comprising a transparent substrate on which is coated a very thin, high optical density, opaque body of imaging material, preferably coated with a thin abrasion-resistant protective layer.  Radiant energy is then momentarily directed to the imaging material through the transparent substrate.  When the heat generated by the absorbed radiant energy is above a given threshold value at a particular location of the imaging material, the material deforms and disperses thereat to form connected or unconnected globules with spaces therebetween.  Upon termination of the radiant energy, that dispersed material becomes frozen in place.   It was discovered that when a surface having projections and/or depressions, (for example, like that found on the surface of animal or plant tissue is brought into contact with  the recording film as described, at least the projecting portions thereof act as high resolution heat sinks which carry away heat from the imaging material in accor-dance with the intimacy of contact between the surface involved to be recorded and the side of the recording film contacted there-by, so that heavily heat-sinked points remain opaque and points unengaged by the surface become relatively transparent, to provide a high resolution picture of the surface topology of the contact-ing body.

Abstract: 1               PHB. 32,630.         ABSTRACT:         A group of infra-red radiation detector elements are manufactured from a body of infra-red sensitive materials on an insulating substrate using two masking steps which do not require critical alignment even with close spacing between the elements.  A first masking layer e.g. of photoresist is formed on the upper surface of at least the body to determine by a lift-off technique a metal-lization pattern on the body and the substrate.  A second masking layer e.g. of photoresist is then provided to determine by ion-bombardment through windows of this layer the desired pattern of elements and their electrodes.  The ion-bombardment permits removal of exposed areas of not just the body and metallization pattern but also of a pas-sivating layer on the body surfaces; a closely spaced group of elements and their electrodes can be obtained because the ion-bombardment results in steep sides with-out significant undercutting.

Abstract: ABSTRACT OF THE DISCLOSURE           Manifolds are disclosed for introducing fluid into the human body and removing fluid there-from.  The fluid removing manifolds include a plural-ity of separately valved containers sealed to the manifold.  Each container is filled in series via the manifold and the associated valve is closed before the container is removed from the manifold for disposal.  Thus, a closed drainage system is provided.  The fluid introducing manifolds include a plurality of separately valved input ports.  Prefer-ably, each port is used only once to reduce contamina-tion of the manifold and associated infection.  In each case, the port is kept closed until it is coupled to a source of fluid, and it is reclosed before the source of fluid is disconnected from the port.  In this way, contamination is further reduced.  Both the multiple input port feature and the multiple container feature of the invention are incorporated in manifolds for use with peritoneal dialysis.

Abstract: APPARATUS TO REDUCE THE EFFECT           OF A MID-TALKSPURT FREEZE-OUT                      Abstract In reconstructing the analog waveform from a syllabically companded delta modulated digital signal transmitted over a TDMA communication channel operating at near its maximum channel capacity, the noise-created in a mid-talkspurt freeze-out is greatly reduced by interpolating the amplitude of the waveform during the freeze-out at the receiver as that of the waveform in the previous period.  This makes the quality of voice transmissions in the face of freeze-outs substantially better than prior art techniques which induce background noise during freeze-outs without the necessity of trans-mitting a voice activity compression (VAC) mask to control the operation of the interpolation apparatus in the receiver.  The interpolation occurs for the first 15 msec sampling period following either a freeze-out or a true VAC operation.  The interpolation operation is supplied only once so that if two or more consecutive sampling periods occur at the receiver where no channels are received for a particular voice port, the background noise is injected into the voice port.  This prevents the uncontrolled repetition of the interpolation at the end of a talkspurt.
