Abstract: TITLE            A METHOD OF REMOVING CARBON-14 FROM PARTICULATE, TON EXCHANGE                           RESIN           INVENTORS          L.P. Buckley, B.L. Woods and W.J. Ward ABSTRACT         Carbon-14 is removed from particulate ion exchange resin by contacting, preferably at 70°C, a bed of the resin with a stream of air, enriched with carbon dioxide, while the particulate ion exchange resin is in contact with water to displace the carbon-14 as gaseous carbon dioxide, and then scrubbing the gaseous carbon dioxide with soluble salts of calcium or barium, e.g. calcium hydroxide and barium hydroxide, to form, as a stable, carbon-14 containing compound, either calcium carbonate or barium carbonate.          The gaseous carbon dioxide may be contacted with an aqueous solution of sodium and barium chloride to form the stable, carbon-14 containing compound which may be immobilized in cement.

Abstract: MOS DEVICE PROCESSING          Abstract of the Disclosure In a metal oxide semiconductor field effect transistor fabrication process, refractory metal is deposited over designated source and drain areas within a silicon substrate.  Refractory metal and silicon at the interface is then mixed by ion implantation of a heavy neutral ion species such as germanium.  To minimize source/drain junction depth, the source and drain locations can be subjected to bombardment by a lighter ion such as silicon which recrystallizes silicon under the designated source and drain regions and so minimizes dopant diffusion.  To render the source and drain of desired conductivity type, an ion implantation of a non neutral ion can be performed.      - i -

Abstract: Abstract of the Disclosure The present invention is directed to a bagging device for directing a flowable substance from a transport trailer to a flexible agricultural bag. The device includes a tunnel housing attached to the back of the trailer.  The open end of the bag is held behind a ridge member and between the ridge member and a stretchable strap so as to resist release of bag until the bag on the ground has been filled. A tray beneath the housing supports the bottom portion of the bag to prevent it from stretching and ripping. A shield near the tires of the trailer prevent the bag from entangling in the tires. The device is especially appropriate for use with flowable commodities such as brewers grains and stillage by-product which rapidly deteriorate unless promptly stored in an air exchange-free enclosure.

Abstract: ABSTRACT OF THE DISCLOSURE     A ring-shaped arrangement of individual work locations.  Tables which are preferably trapezoidal are arranged in a ring, in the middle of which is disposed a region which is free of table tops, and in which can be disposed common supply lines or the like.  The individual work locations, which are arranged around the central region, are respectively separated from an adjacent table by a vertical partition in which is disposed a material-transfer opening.          The supply of material to the individual work locations can be effected from supply bins disposed on a shelf supported above the ring-shaped table top on the upper edges of the radially directed partitions.          If it is a question of small parts, the latter can be transferred to the work location via conveying tubes, which lead from the supply bins on the shelf to the table top of the individual work locations.

Abstract: ABSTRACT         Apparatus whose measurement means consists solely of electronic components, measures the power taken by an electrical load connected to an alternating source of electricity supply in such a manner that the power sensed or energy accumulated is in agreement with the same measurements as performed by a conventional rotating disc electromechanical meter. Fundamental frequency filtering means when applied to either one or both supply voltage and load current ensure that the electronic circuitry performs the appropriate measurements in determining power consumption.          A single sample per mains cycle applied to load current and supply voltage is sufficient to measure power consumption, energy consumption accumulation, and produce accumulated energy pulses appropriate to measurement of real power, true power and volt-ampere power consumed by the load.          Similar multiphase meters apply the fundamental frequency filtering means to each load current and optionally to each supply voltage to extend the method used in single-phase meters.          To improve accuracy of the measurements where an analogue to digital converter is used the current signal, and optionally the supply voltage signal, is perturbed by a Quantisation Error Dispersion (Q.E.D.) signal.         Various circuits are described to generate the Q.E.D. signal and the essential properties of the signal are defined.

Abstract: DIGITAL SCAN CONVERTOR             ABSTRACT OF THE DISCLOSURE A digital scan converter having an oscillator providing a clock signal used to scan-convert an input video signal to thereby produce a scan-converted output video signal, an automatic frequency control for controlling the oscillator in synchronism with a synchronizing signal separated from the input video signal and a counter for frequency-dividing the clock signal from the oscillator to thereby form a control signal used for controlling blanking of the input video signal.  The counter also provides an address signal for a memory in which the video signal is temporarily stored during the scan converting operation.          Since a composite blanking pulse for the input video signal is formed in synchronism with the address signal for the memory, it is possible to prevent appearance of a jitter of the composite blanking pulse on a display screen.

Abstract: METHOD AND APPARATUS FOR IMPLEMENTING A  THERMODYNAMIC CYCLE WITH INTERCOOLING                          ABSTRACT      A method and apparatus for implementing a thermo-dynamic cycle with intercooling, includes a condensing subsystem, a boiler, and a turbine.  The boiler may include a preheater, an evaporator, and a superheater. After initial expansion in the turbine, the fluid may be diverted to a reheater to increase the temperature avail-able for superheating.  After return to the turbine and additional expansion, the fluid may be withdrawn from the turbine and cooled in an intercooler.  Thereafter the fluid is returned to the turbine for additional expansion. The cooling of the turbine gas may provide additional heat for evaporation.  Intercooling may provide compensation for the heat used in reheating and may provide recupera-tion of available heat which would otherwise remain unused following final turbine expansion.

The method mixes the ingredients then allows a froth to form and cure at ambient temperature to an elastomeric silicone foam.  The method mixes a vinyl-containing polydiorganosiloxane (1), a hydroxylated polydiorganosiloxane (2), a platinum catalyst (3), an organohydrogensiloxane (4) and a profoamer (5).  The profoamer is a resinous, benzene-soluble organosiloxane copolymer consisting essentially of SiO4/2 units, silicone-bonded hydroxyl groups, (CH3)3SiO1/2 units, and fluorine-containing units.  An embodiment of the method includes a liquified blowing agent and stores the mixture under superatmospheric pressure, forming a foam by releasing the mixture to atmospheric pressure.  Another embodiment includes an alcohol in the mixture to provide a foam of lower density. When lauryl alcohol is used and the alcohol is mixed with (1), (3), and (5) before (2) is admixed, the foam has a Bashore resiliency of less than 20.
