Abstract: D-5,500 MULTIPLE FUNCTION SWITCH ASSEMBLY        Abstract of the Disclosure A combination turn signal switch and dimmer switch assembly for automotive vehicles comprises a two part lever comprising an actuator and a handle. The actuator is pivoted to a switch housing for rocking movement about an axis on either side of a neutral position for selective turn signal switch actuation.  The handle is pivoted to the actuator about an axis transverse to the actuator pivot axis and is movable between a neutral position and a dimmer switch actuation position.  The handle has a V-shaped ramp surface engaged by a leaf spring which serves to press the handle toward its neutral position as well as to cam the actuator toward its neutral position. The turn signal switches are keyboard switches mounted on a printed circuit board secured to the housing. The switches are spaced below the path of the actuator and are actuated by forces perpendicular to the actuator path.  Spring elements or flexible levers secured to the circuit board and contacting the switches extend into the actuator path.  Deflection of a flexible lever by actuator movement transfers actuating force to the corresponding switch.

Abstract: ABSTRACT OF THE DISCLOSURE A lens-shaped article or the like which has a support frame formed as a unitary structure with the outer periphery of the lens-shaped body, is described together with a method and apparatus for the manufacture of such a lens-shaped article.  The manufacturing method and apparatus are of particular utility when employed for the manufacture of small resonators.  Also when the resonators are formed as small as possible, it is possible to obtain high Q and prevent sub-vibration.  In the case of a framed lens, it can easily be assembled with high precision.  In the novel method, a workpiece from which the lens-shaped article is to be formed is held by one work holder.  One sur-face of the workpiece is then machined about a reference centre axis.  A machinable piece is then attached by adhesive to the machined surface of the workpiece.  A spherical surface is then machined on the machinable piece and the machinable piece and workpiece subsequently transferred together to another work holder which holds the assembly by suction acting on the spherical surface of the machinable piece.  The other surface of the workpiece is then machined about the reference centre axis after which the machined workpiece is dis-assembled from the machinable piece.

Abstract: MOTOR HEATING CONTROL WITH INTERLOCKED DUAL ISOLATING SWITCHES                  Abstract of the Disclosure A motor heating control for retrofit applications has an enclosure with power supply terminals and motor heating output terminals.  Inside an upper compartment is a first two-pole isolating switch which couples power from the supply terminals through a step-down transformer and a rectifier to one side of a motor heating contactor in the lower compartment.  The other side of the motor heater contactor is coupled through fuses and a second two-pole isolating switch in the lower compartment to the motor heating output terminals.  An operating handle outside the lower compartment is mechanically interlocked to both isola-ting switches so that the door of the enclosure cannot be opened without disconnecting both the motor heating power source and the electrical motor from the motor heating control.  The motor heating contactor is also electromechan-ically interlocked to the door interlock mechanism so that the operating handle cannot be moved to its open position until the motor heating contacts are opened.  When the motor heating contacts are closed, current will be supplied to at least one motor winding to maintain a temperature of 5-10°          F. above the ambient and prevent condensation in the wind-ings of a motor.

Abstract: TITLE:  SOLDERING IRON HANDLE STRUCTURE   ABSTRACT      A relatively inexpensive electric soldering iron and handle structure can be constructed so as to be relatively simple to assemble by utiliz-ing cooperating holding elements within a tubular handle to form a holder.  This holder serves to support or hold a socket adapted to support a heating element and a cord retainer in place within the handle.  The holder is in turn held in place within the handle through the use of coop-erating detent elements on both the holder and on the handle.  The parts of the soldering handle structure are dimensioned so that the parts pre-viously identified can be inserted as a unit into the handle through one end of the handle as the cord is withdrawn outwardly from the other end of the handle.

Abstract: A B S T R A C T         A method of making a thermally actuatable electrical switch involves the locking of a conductive lead, passing in a bore through an end plug of a housing of the switch, to the end plug by skiving the lead and compacting the skived part of the lead against one end of the end plug so as to render the lead immovable in a direction towards the other end of the end plug, as well as immovable rotationally.  A contact on the lead, abutting the other end of the end plug, will thus be securely fixed in position relative to the end plug. When the skived part is being compacted against the one end of the end plug, a portion of the skived part may be caused to enter the lead-carrying bore in the end plug to center the lead in the bore and to augment the locking effect. Further augmentation of the locking effect may be achieved by applying a hard-setting sealing compound, such as an epoxy resin, over the compacted skived part so as to extend over respective portions of the end plug and the lead on opposite sides of the compacted skived part, whereby some of the sealing compound prior to setting will seep into the bore by capillary action to engage the portion of the skived part therein and some will fill recesses produced on the lead by the skiving step.  The thermally actuatable electrical switch itself is unique by virtue of having a skiving of its conductive lead interlocked with an end of the end plug, a portion of which skiving may be interlocked with the wall of the lead-carrying bore in the end plug and with sealing compound in the bore, which compound may be inter-locked with recesses in the lead outboard of the bore, as well as with the skiving which is locked to the end of the end plug.

Abstract: ABSTRACT OF THE DISCLOSURE     A delay circuit comprising a pair of modulators for executing biaxial quadrature modulation with carriers that have a 90° phase difference therebetween, a signal mixer which mixes the modulated output signals of the modulators together to produce a composite output signal, delay circuitry for delaying the composite output signal of the signal mixer and a pair of demodulators which are respectively associated with the pair of modulators and serve to demodulate the delayed output signal supplied by the delay circuitry.  The first of the two demodulators associated with the first of the two modulators, produces a first demodulated output signal, a portion of which is supplied to the second of the two modulators as a modulating signal.          Additionally, the first demodulated output signal is delayed by the delay circuitry for a predetermined duration with respect to an input signal fed to the first modulator.  The second demodulator associated with the second modulator produces a second demodulated output signal which is delayed for twice the predetermined duration of the first modulator input signal.

Abstract: HIGH-SPEED MERGED PLANE LOGIC FUNCTION ARRAY     Abstract of the Disclosure A programmable logic array includes a plurality of MOS switching devices formed at preselected locations in an array made up of input and output lines and intersecting product term lines.  One group of MOS devices constituting the "AND" plane arranged at the intersections of the input lines and product term lines performs a logic operation on input signals to the array and outputs logic signals onto the product term lines.          A second group of MOS devices constituting the "OR" plane located at the intersections of the output lines and product term lines receives the outputs of the "AND" plane devices and performs a logic operation on those signals to produce a set of output signals that are presented at the outputs of the array for use by an external device.   The merged plane array of the invention advantageously includes dual-gate MOS devices as switching elements to reduce the capacitance on the product term lines and output lines and thereby to increase the operating speed of the array.   The input and output lines and related MOS devices of the array rather than being arranged in physically separate and distinct input "AND" and output "OR" planes, as in the prior art, are interspersed or merged with one another so as to reduce the amount of interconnect required between the logic array and an external device which provides the inputs to the array and receives the outputs therefrom.

Abstract: ABSTRACT OF THE DISCLOSURE          A fluid-operated, load-handling apparatus is provided for handling loads of various weights.  The apparatus includes a fluid-operated hoist with an elongate member extending down-wardly to a load-carrying unit.  A pilot fluid-controlled regu-lator supplies fluid to the hoist and a load-responsive, pilot fluid regulator is carried by the load-carrying unit and supplies pilot fluid to the pilot fluid-controlled regulator.      The pilot fluid is varied according to the weight of a load, being higher for heavier loads and lower for lighter loads so that the pressure of the fluid supplied to the hoist is accordingly varied by the pilot fluid-controlled regulator to automatically balance the load carried by the load-carrying unit. The apparatus also can include a brake for preventing the alongate member from moving up or down while loads are being changed or are at rest.
