Abstract: ABSTRACT OF THE DISCLOSURE      A ballast circuit for starting and operating gaseous discharge devices includes a transformer which has a primary winding and a secondary winding. There are auxiliary windings electrically coupled to the primary winding, including electrode windings for providing energy to heat the electrodes of the gaseous discharge devices. There is a relay including a heater and a switch. The switch is normally open and closes in response to energization of the heater. The heater is connected to an auxiliary winding for energization when the primary winding is energized. The switch is connected in series with the secondary winding for providing operating energy to the gaseous discharge devices only when the switch is closed.

Abstract: ABSTRACT OF THE DISCLOSURE    Foamed liquid mixtures are applied to substrates, in particu-lar foamed plywood glues are spread on traveling wood veneers in the manufacture of plywood, by a method comprising the following steps:  The liquid is withdrawn from a source of the same and foamed.        The foam is continuously extruded or otherwise spread on an inter-mittently moving substrate during the periods of motion of the sub-strate.  The foamed liquid is continuously diverted from the sub-strate during the periods of rest of the substrate,  The diverted foamed liquid then is defoamed and cycled back to the liquid source where it is mixed with fresh liquid.  This makes possible applying a uniform spread of the foamed liquid on the substrate even though the motion of the substrate is started and stopped at frequent in-tervals.

Abstract: ABSTRACT           An antenna and scanning means therefor particularly use-ful in an aircraft landing system operating in the microwave frequency range.  The antenna is of the line phased array type which includes digitally controlled phase shifters for each of the radiating elements of the array.  The beam formed by the antenna is steered by incrementing the phase shift applied at each of the array radiating elements by an amount of phase which is dependent in part upon the position of the radiating element in the array.  Phase increments sufficient to shift the beam position by one coarse step (0.01°) are supplied to symmetri-cally located radiating element pairs, pair by pair, until all elements have been incremented.  The beam is thereby caused to move through one coarse step in a number of fine steps equaling the number of pairs of elements in the array.  An additional feature of the scanning means is the application of phase in-crement to the array elements in a pseudo-random sequence.

Abstract: ABSTRACT           An improved process for treating wood which has been impregnated with a solution of a treating agent in a suitable solvent.  After the impregnation step, the wood is steamed at an elevated temperature and superatmospheric pressure, thus causing the solvent to condense on the sur-face of the wood.  The pressure is then reduced to atmos-pheric pressure and the steaming continued until essentially all of the solvent is removed from the wood.  By this pro-cess, deposits of treating agent crystals and wood exudates are largely removed from the surface of the wood.

Abstract: OVERCENTER TYPE LATCH            Abstract of the Disclosure An overcenter type latch for relatively movable members includes a retainer of molded plastic secured to one member and having spaced recesses adjacent one end thereof and a striker adjacent the other end thereof.  An operating handle has spaced abutments adjacent one end thereof received within the retainer recesses for pivotal movement of the handle between an overcenter latched position and an unlatched position.  An elastomeric link is pivoted to the operating handle and to other member.  The link is tensed when the handle is in latched position and extends between the spaced recesses and abutments.  A manually operated latch integral with the handle cooperates with the striker to block movement of the handle to unlatched position unless the latch is manually released.

Abstract: PRELOADED TIE ROD END ASSEMBLY             ABSTRACT OF THE DISCLOSURE         A preloaded tie rod end assembly for a motor vehicle steering system and the method for making the assembly is disclosed.  The tie rod end is made by positioning first and second frangible bearings against the ball of a ball stud and enclosing the ball and bearings in first and second housings each of which has a socket part and a stem part.  A plastically deformable element is also situated within the socket formed by the two socket parts.  The two housings are held together under a compressive load while their abutting edges are butt welded.          The imposition of this load during the welding operation causes the frangible bearings to each fracture into a plur-ality of self-aligning bearing pieces.  The deformable element is plastically deformed by exerting a force on the ball stud whereby a portion of the preload of the joint is relieved.          The preload is relieved to the extent necessary to bring the frictional resistance to rotation of the ball stud within a prescribed torque range.

Abstract: SOLID STATE OVERLOAD RELAY TRANSFORMER CIRCUIT            Abstract of the Disclosure A self-powered solid state overload relay having current transformers energized by current to a motor to be protected.          The transformer has secondary windings connected through diodes to charge a capacitor in a circuit which senses the magnitude of motor current and capacitors in a trip-reset circuit which causes the circuit to be interrupted when the motor current exceeds a pre-programmed value.  The diodes in capacitor charg-ing circuits are poled so that the capacitor in the sensing circuit and the capacitor trip-reset circuit are charged by opposite polarity rectified half wave current pulses.  The cores of the transformers are sized and impedances are included in the charging circuits to cause the capacitors in the trip-reset circuit to be fully charged before the capacitor in the sensing circuit is charged to a level which would cause the relay to operate to interrupt the motor circuit and the cores of the transformers to saturate in one direction on their associated hysteresis loops when the capacitors in the trip-reset circuit are being charged and in the opposite direction after the capacitor in the sensing circuit is charged.
