Abstract: ABSTRACT OF THE DISCLOSURE    An improved method and apparatus for growing mercuric iodide (HgI2) crystals which combines known vapor growth techniques to produce larger, more uniform, and higher perfection crystals for use in X-ray, nuclear, or other radiation detectors.  The improved method combines the following individual crystal growth techniques:          (a) growth at low supersaturations and/or undercooling, .DELTA.T;          (b) pulling the crystal so that the pulling rate is equal to growth rate in the gradient and the crystal thus grows at a constant .DELTA.T; and (c) oscillating the temperature of the source TS between TS1 > TC and TS2 < TC where TC is the temperature of the growing crystal.

Abstract: ALLOY                 ABSTRACT OF THE DISCLOSURE       A cobalt-base alloy particularly for the cast parts of gas engines which operate at high temperatures, such as stationary blades of turbines, vanes of large cross-sectional and the like.  The alloy has the minimum practicable of zirconium so that detrimental inter-dendritic carbide oxidation is suppressed.  The surface of castings of this alloy readily lend themselves to coating with oxidation and sulfidation resistant coatings.  In addition, the carbide oxidation attack of the crucible in which the alloy is melted or molded is minimized so that the economy of producing castings is materially improved.  Also, improved is the internal structure of the investment castings produced in normal shop practice; i.e., equiaxed grain size, as distinct from columnar grain size, is produced and this results in an increase in the integrity of cast properties in large castings.          The creep resistance of the alloy is further improved by including a small but effective quantity of aluminum in the composition cooling conditions for the casting of this alloy are less critical than for prior art alloys; finer dentrite arm spacings can be obtained under normal current casting shop processes.

Abstract: TIME DIVISION SYSTEM FOR SYNCHRONIZING FUNCTIONS CONTROLLED BY DIFFERENT CLOCKS           ABSTRACT OF THE DISCLOSURE: Synchronization control circuit for a time divisional data transmitting and receiving system. Data is received at an exchange at a clock rate determined by the transmitting station and is stored in memory at the incoming rate. The memory has cells for temporarily storing each bit of a coded combination, as received. Read-out of data from the memory is based on the internal clock rate of the exchange. Since only one operation - read or write - can occur on a memory at any one time ant the operations are controlled at rates which may be out of synchronism with one another, conflicts may occur. To prevent such conflicts, an exclusion circuit is provided to evaluate the interval separating reading and writing operations and to produce a time shift of predetermined duration between operations when the out-of-synchronism interval is less than a predetermined time interval.

Abstract: Abstract of the Disclosure Apparatus for cutting an extrudate to finished length includes a hopper that receives rough-cut lengths of extrudate, and feeds them one at a time to holders on a movable carrier. Each holder captures a length of extrudate which is transported by movement of the carrier to a pair of heated blades spaced apart a distance equal to the desired finished length of the extrudate. The blades serve to cut a portion from each end of the extrudate in a holder, whereby the extrudate is trimmed to finished length, and, simultaneously to fuse the material of the extrudate at the end faces, thereby sealing such faces. Further movement of the carrier enables the holders to release the trimmed extrudate onto a conveyor.

Abstract: ABSTRACT       The invention provides a "COORDINATED HEAT PUMP SYSTEM" which simultaneously satisfies the thermal needs of both the heat source and the heat sink.  The heat pump system of the present invention is adapted to continuously withdraw heat from a heat source and continuously deliver heat at a required rate to a heat sink such that the ratio of the heat delivered to the heat withdrawn may be controlled by a cooling means, said heat pump system comprising a compressor adapted to compress at least a portion of refrigerant vapour from an evaporator thereof  wherein a refrigerant withdraws heat from said heat source, a condenser in which refrigerant vapour so compressed is condensed and delivers heat to said heat sink at the required rate, a cooling means for balancing the rates of heat delivery and heat withdrawal, an expansion valve for expanding liquid refrigerant from said condenser into said evaporator, and a liquid-vapour suction line heat exchanger for adequately superheating the refrigerant vapour prior to its compression in said compressor.  The coordinated heatvpump system of my present invention can be advantageously employed in processes and systems such as ordinary drying with air, vacuum drying, freeze-drying, etc. used in processing of fish, food and chemicals as well as in many other situations requiring the two thermal needs (the cooling and the heating) to be simultaneously satisfied, thus not only substantially eliminating the need to supply heat from any external heat or energy source but also drastically reducing the heat that other-wise must be rejected into the environment.

Abstract: METHOD AND APPARATUS FOR MINIMIZING STEAM CONSUMPTION IN   THE PRODUCTION OF PULP FOR FIBERBOARD AND THE LIKE              ABSTRACT OF THE DISCLOSURE Method and apparatus for minimizing steam consumption in the production of pulp used for the manufacture of fiberboard and the like, in which chips of cellulosic material are ground in a de-fibrator or refiner in an environment of saturated steam above 100°C and corresponding steam pressures.  The chips are normally presteamed with atmospheric steam separated from the pulp at the discharge end of the defibrating process to a temperature between 90°C and 100°C and compressed and dewatered to a dryness of at least 50% and then passed into a preheater which forms part of the defibrating or refining apparatus, where the compressed and de-watered chips are heated to the desired defibrating or refining temperature, usually ranging between 130°C and 200°C, by a portionof the high-temperature high-pressure steam generated by the heat of friction in the grinding space of the defibrator, which portion upon discharge from the grinding housing, is separated from the pulp and recirculated under increased pressure above the discharge pressure.  If the other portion of the discharged atmospheric steam, upon separation from the pulp, should not have sufficient neat content to presteam the raw chips to the desired temperature, fresh pressurized steam may be added to the recirculated portion of the steam to impart to the other portion of the discharged steam the required capacity.
