Abstract: Slotted Heat Sinks For High Powered Air Cooled Modules Abstract An air cooled high density integrated circuit system wherein heat sink structures are located on one of the surfaces of the modules in the system.  The heat sink is composed of a plurality of hollow or flat heat con-ductive bodies having an opening or openings extending from the module surface toward, but not reaching, the top of the hollow heat sink.  Means are provided to direct air flow to the upper end of the body.  The air flow will be from the top of the heat sink and out of the opening or openings to cool the heat sink and the module.  The heat sink structure provides greater sur-face area and effects the breaking up of the boundary layer near the surface of the module for enhanced cooling.

Abstract: Abstract of the Disclosure Detection of wet and icy surface conditions on the surface of a pathway is accomplished using a block of electrically insulative material embedded in the pathway with its top surface flush with the sur-face of the pathway and exposed to atmospheric precip-itation.  A sensor electrode is encapsulated in the block and is positioned a predetermined distance be-neath the top surface of the block so that an accumu-lation of atmospheric precipitation on the top surface affects the capacitance and conductance between the sensor electrode and the pathway.  Provision is made for detecting the presence of impurities such as salt on the block's top surface.  A time-varying electrical current is supplied to the sensor electrode at at least two different predetermined frequencies.  The apparatus is relatively sensitive to impurities on the block's surface at one of the predetermined frequen-cies and is relatively insensitive to impurities at the second predetermined frequency.  The frequency of the current supplied to the sensor electrode when substantially pure precipitation is present on the block's top surface is the first predetermined fre-quency and the frequency of the supplied current is the second predetermined frequency when impurities are detected.  The presence of precipitation is signalled when the capacitive and conductive losses between the sensor electrode and the pathway are indicative of such precipitation on the pathway.

Abstract: ABSTRACT         An atrial-ventricular demand pacemaker having improved atrial pulse artifact rejection includes a blanking circuit connected in the signal path from the ventricular output terminal to the sensing amplifier to blank the signal during an atrial pulse.  A holding circuit including a low-pass filter and a switching element stores a prior signal value at the sensing amplifier input during the blanking interval, and delays return to normal operation until after the blanking circuit has returned to normal.  Artifact rejection is also improved by limiting atrial pulse output circuit recharge time and by limiting polarization current driven into the ventricular output circuitry by an atrial output pulse.

Abstract: ABSTRACT OF THE DISCLOSURE, Molecules or cells of materials exhibiting a micro-biological activity, suppression or interaction of interest are isolated from a large population of similar molecules, cells or the like.  The activity of the microbiologically active molecules or living matter of interest is measured by suspending the population in a liquid medium capable of forming a gel.  The resultant suspension is formed into droplets which are caused to gel.  The gel droplets (GMDs) are treated to effect desirable alteration of the micro-biologically active material and the amount of metabolites or reaction products of the desired alteration within each of the gel droplets.  Alternatively, incubation is carried out such that each GMD initially containing one cell con-tains many, a microcolony, which can be tested for desirable properties while retaining sufficient viable cells for further growth and harvesting for further testing and/or production.  The gel droplets are then separated based upon the measured or sensed characteristic, metabolite or reac-tion product.
