Abstract: TITLE A DUAL RAIL TIME AND CONTROL UNIT FOR A   T-S-T-DIGITAL SWITCHING SYSTEM            ABSTRACT A time space-time switching network is shown in which there is a crossover of voice information from one rail to another rail in a large digital switch-ing system.  The time and control unit is divided into two rails both incoming and outgoing.  Each rail multiplexes two 193 channel streams into one 386 chan-nel stream of information.  These two rails crossover in the terminating time switching stage but remain segregated throughout the space switching stage.

Abstract: ABSTRACT OF THE DISCLOSURE     In a system using the double absorption process for sulphuric acid manufacture, a single acid circulation system and a single cooler are employed.  Acid from the exit of the air drying tower is circulated to and flows through the final absorber where it absorbs the inlet SO3 gas before joining with the acid from the intermediate absorber. The mixed stream is then cooled and split between the drying tower and the intermediate absorber.  The circulation arrangement reduces the cooling to one relatively high tem-perature location, eliminates the transfer of SO2 to the effluent  gas from acid in the normal single system, and simplifies acid strength and level control.

Abstract: ABSTRACT OF THE DISCLOSURE          Semiconductive barium titanate having a positive tempera-ture coefficient of resistance comprises a barium titanate semiconductor including barium titanate and a small quantity of a doping element, and at least one additive selected from among silicon nitride, titanium nitride, zirconium nitride and silicon carbide.  The semiconductive barium titanate of this invention has a sharp rise in the variation of specific resistivity with temperature change and a large specific resistivity ratio in the PTC temperature region, and can be produced with high reproducibility, since a widely differing quantity of the doping element can be effectively added to barium titanate.

Abstract: ABSTRACT For a dynamic balancing machine the values of parameters employed to determine the weight, rim spacing and diameter of a wheel are automatically entered into the balancing machine by a single maneuver of an extensible wand. This simplicity eliminates many opportunities for human error when obtaining the same information otherwise.  The wheel balancing machine is of the type having a frame, a drive shaft for rotating the wheel and a computing device for carrying out calculations to derive the value of the space between the rims of the wheel.  A sensor senses forces representative of first and second por-tions of the weight of the wheel detected at first and second portions along the drive shaft, the sum of the first and second portions being substantially equal to the total weight of the wheel.  The displacement between one of the portions and the adjacent flange of the wheel is detected.  Electrical signals re-presentative of the first and second forces and the displacement are sent to the computing device.

Abstract: ABSTRACT          Used foundry sand is reclaimed by subjecting it to both mechanical and thermal treatment whilst recirculating it in a container.  The sand is recirculated through a stream of hot gas which raises the surface temperature of the grains sufficiently to destroy the binding properties of residual binder adhering to the grains, and fines produced by abrasion of the sand grains are extracted.  Since it is only necessary to heat the sur-faces of the grains during processing, and removal of residues is carried out in the same container, the system is economical both in terms of energy consumption and the apparatus required.  The apparatus may be a tilted rotating drum containing a high speed energizing rotor, and a burner or hot gas source producing a gas stream impinging upon the sand grains being circulated by the rotor.

Abstract: Abstract of the Disclosure A shaped charge warhead comprises a fragmenting wall defining a space which contains a shaped charge liner that is conical in shape having a large diameter base.  The space between the liner and wall is filled with high explosive with a portion of the space adjacent the liner base being disposed by a support ring which interconnects the liner base with the wall.  The reduc-tion of explosive near the line of base and the provision of the supporting ring improves the velocity configuratlon of a jet formed by the exploding warhead in that the velocity of the jet tail is reduced with respect to the velocity of the jet tip.  The jet thus formed has increased an attrition capacity for antimaterial purposes.
