Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides an integrated circuit using an insulated gate field effect transistor of the punch-through type.  The insulated gate field effect transistor is formed in a semi-conductor substrate of a predetermined conductivity type and has a source electrode, a gate electrode, and a drain electrode.  The source and drain  electrodes are lo-cated in different regions of the surface of the substrate, and the gate electrode is located on a gate insulating layer formed on the semiconductor substrate between the source and drain  electrodes.  The impurity concentration in the semiconductor substrate, the channel length between the source and drain electrodes, and the thickness of the gate insulating layer are selected so that the insulated, gate field effect transistor is rendered non-conductive in the absence of a gate voltage applied to the gate electrode, and the effect transistor  is rendered conductive due to the punch through effect between the source and drain, electrodes when a gate voltage of a predetermined polarity is applied to the gate electrode.  This invention is par-ticularly useful for an integrated circuit in which a high speed operation is required, and overcomes difficulties previously encountered with the punch-through type effect transistor in that it provides an integrated circuit having a high operation speed, uses an insulated gate field effect transistor  of punch-through type having a normally-off characteristic, and it provides integrated logical circuits for electronic computations.

Abstract: STOVE-HEARTH COMBINATIONS  A b s t r a c t Stove-hearth combinations which comprise a combustion chamber having a pair of side walls supported on a base in opposing relation and joined by a rear wall. A cover or hood defines with the base and front edges of the side walls an opening to the chamber. Two doors are each hingedly associated with upper and lower pivot pins which when the door is in a closed position are disposed adjacent but outside a respective side wall front edge. Along upper and lower side edges of each side wall are formed parallel grooves adapted to be engaged slidably by the upper and lower pivot pins. As the door is opened from a stove to a hearth position the pivot pins are displaced along the grooves causing the door to be led gradually into a position along the outer side of its side wall.

Abstract: TOTAL POWER FLUID SYSTEM VEHICLE WITH STEERING CONTROL     Abstract of the Disclosure A vehicle with a total power fluid system includes a pair of drive wheels, variable displacement, fluid motors driven by an engine driven, variable displacement, fluid pump.  The motor displacements are controlled by operator speed input and speed sensing controls, and the pump displacement is controlled by a pressure sensing pressure control.  A vehicle steering control includes an operator steering input control connected to a steer-able wheel control for actuating a valve for holding, turning, or castering fluidly steerable wheels which are capable of turning the vehicle.  The operator steering input control is further connected to the operator speed input controls to slow the turn-side drive wheel motor during either a steerable wheel controlled or an emergency, drive wheel controlled turn.  During either an electrical failure or a hydraulic failure sensed by the inability of the steerable wheels to follow the operator steering input control, the valve will be actuated to caster the steerable wheels.  The operator steering input control further includes provisions for greater steering sensitivity near the centered steerable wheel position and for limiting the degree of steerable wheel turn with increasing vehicle speed.

Abstract: Abstract A wire matrix for a construction panel has a plurality of parallel longitudinal trusses, each truss having a pair of parallel longitudinal wire runners and a plurality of trans-verse wire struts in which the struts associated with one truss are all parallel to each other and extend diagonally between the parallel runners, with the struts in alternate ones of the trusses being parallel and the struts in adjacent trusses being skewed.  The trusses are formed by making a grid of parallel longitudinal runners joined by diagonal cross wires which are then cut between adjacent pairs of runners to form separate trusses.  The trusses are then joined by trans-verse wire runners forming a three-dimensional matrix.

Abstract: ABSTRACT OF THE DISCLOSURE           An improved metal pallet is shown having elongate deck members defining a load bearing surface and transverse stringer members to support the deck members.  The stringer members are generally U-shaped having generally upright laterally resilient sides defining longitudinally spaced-apart, transverse openings located adjacent to the upper marginal edges of the sides.  The ends of the deck members pass through the stringer member openings.  The deck members have longitudinal downwardly and outwardly disposed laterally resilient sides defining opposed pairs of parallel slot openings.  The longitudinal spacing between these slot openings is different than the normal transverse spacing between the stringer sides,  so that upon assembly of the pallet the stringer and deck member sides are laterally deflected;  the peripheral edges of the stringer openings are located in the slot openings, and the deck members and stringer members are biased into mutual engagement by the lateral deflections of the respective sides.

Abstract: ABSTRACT OF THE DISCLOSURE       A method of making signs is disclosed in which a photographically sensitive material is imagewise exposed and developed.  The developed image is so constituted that, under the action of heat and pressure, it may be made to adhere to a surface of a transparent or translucent sheet, e.g. of plastics or glass, to form a sign in which the legend is visible through and protected by the sheet.  In order to render the legend more visible, a coating or layer may be applied over the legend which accordingly forms a background to the legend as viewed through the sheet.       Production of the legend phototgraphically gives very great flexibility in terms of letter size, spacing and the like and allows the production of "one off" signs on a rapid and economic basis.  A simple hot press may be used to adhere the legend to the sign sheet.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is an arrangement for producing alternating current by using a dc generator which permits the output frequency to be controlled or synchronized with another alternator so that the outputs can be parallel connected without reverse current protection and without elaborate speed control of the prime mover.  A controlled alternating current is fed in three phase to the field windings of the dc generator.  The commutator means are connected to the armature windings and to output terminals to provide three phase output.  By supplying the field windings with a controlled frequency current and rotating the armature, an alternating signal will spear at the output terminals similar in frequency to that applied to the field windings. The frequency generated is independent of rotational speed of the armature. The arrangement is suitable for supplying ac to equipment carried in mobile units.

The reactor has been designed to provide initially a large inductance and to provide a finite unsaturated state at very high arc load currents.  Control of the firing angle of the thyristors is under voltage and current feedback control with overriding gate pulse suppres-sion at will by the operator, or under an emergency.  The gating angle is automatically reset after gate pulse suppres-sion has been applied, and normal welding operation under feedback control is gradually restored after gate pulse suppression has been removed.

Five to sixty parts per million (of the bitumen contained in the tar sand) by weight of a commercial defoamer is added to the tar sands on a conveyor belt as it flows into the conditioning drum.  As a result, the froth de-aerates in the separation cell and becomes pumpable by cen-trifugal pumps without further treatment.
