Abstract: An electrical terminal having a wire clamping tab connected thereto by an essentially thin neck portion about which a wire coated with a resin-type, high temperature insulation is adapted to be wound so that, when the tab is bent back against the terminal by opposed, energized electrodes to clamp a portion of the wire extending from the neck portion therebetween, resistance of the latter to flow of current heats both the neck portion and the wire wrapped therearound sufficiently to explode the insulation from the wire to assure a good electrical connection. At the same time the relatively large area of the terminal and its clamping tab maintains the clamped portion of the wire below its annealing temperature so that it is resistant to breakage in use.

Abstract: An improved electronic controller for an automobile power seat system is disclosed. The electronic controller features a microcomputer which receives command signals from a first and second group of operator actuable switches, present position signals from a monitoring circuit, and stored position signals from a memory circuit for generating control signals for directing a motive power means to adjust the position of an automobile seat. The monitoring circuit includes transducer means for sensing the current draw from the d.c. power source, and differentiating means connected to the transducer means for generating a pulse concomitantly with each commutation of the motor from the motive power means. These pulse position signals are sent to the microcomputer and then counted by an internal timer for determining the present position of the automotive seat.

Abstract: An electrical switch having general utility but intended primarily for use in automotive vehicles. The switch comprises a case and one or more terminal blades and is readily adaptable for a variety of different environmental conditions. The case and the blades are uniquely formed and correlated so that the case effectively insulates each blade from the others and from adjacent metallic parts of the vehicle, so that the components can be quickly and easily assembled and for inexpensive manufacture. Each blade is cantilevered from the case to provide a soft action that results in a relatively long life but at the same time maintains a good electrical connection with a compatible switch part.

Abstract: An inertial lock for the electric actuated release mechanism of a door latch, said release mechanism comprising a solenoid and plunger and said inertial lock comprising a spring biased inertial ring disposed on an extended portion of the solenoid and operably associated with spring biased locking tabs operable to lock the plunger in place during conditions which would provide forces that might undesireably actuate the release mechanism, such as certain vehicle accident conditions. This inertial lock is set within the confines of a conventional electric latch release mechanism, not requiring additional space, and features have been incorporated into the design to ease assembly of the electric actuated release mechanism and aid in the collection of flux from the solenoid.

Abstract: A solenoid spool having a Bowden cable connector that is made in two parts which are uniquely formed and related to the solenoid plunger to cover and protect the latter from dirt and other contaminants that adversely affect the operation of the solenoid in use. One part of the connector attached to the cable sheathing is piloted on and detachably fastened to the other part which is attached to and a part of the solenoid bobbin or spool in a way that positions the cable wire precisely automatically at assembly for attachment to the plunger.

Abstract: A molded pressure ring adapted primarily for holding the peripheral marginal portion of a diaphragm in a tone generator under uniform light pressure so that the tone does not change significantly under normal changes in ambient conditions of temperature and pressure; more particularly the ring comprises an outer annular body having circumferentially equi-spaced, radially inwardly extending, generally U-shaped, independently movable, flexible and resilient cantilevers provided at the free ends thereof with pressure applicators arranged to engage and hold the diaphragm under pressure exerted by torsion-stressed portions of the cantilevers.

The control logic and timing circuit for the tone generator includes a unique PTC subassembly that provides a timed logic signal for controlling the activations of the diaphragm, as well as an independently generated signal for contemporaneously activating a lamp which provides a visual indication of the detected predetermined condition. The control logic and timing circuit is adapted to produce the proper timed logic signal despite the absence of a lamp in the circuit or a lamp failure.

Abstract: A control circuit for a tone generator that is adapted to cause the tone generator to produce a plurality of readily distinguishable audible sounds, including a chime sound, a pulse tone and a steady tone. The control circuit has particular application for use on an automobile to monitor such conditions as "seat belts buckled", "headlamps on", and "key in the ignition". The control circuit includes three oscillator circuits that are adapted to produce square wave output signals at three different frequencies. The chime sound is generated by pulse width modulating the highest frequency signal and "restriking" the decaying sound at the frequency of the lowest frequency oscillator. The steady tone is produced by driving the tone generator directly with the output signal from the highest frequency oscillator. To generate the pulse tone, the highest frequency oscillator is repeatedly enabled and disabled in accordance with the output signal from the middle frequency oscillator.

Abstract: A carburetor of the slide and pin type having a throttle slide mounted in grooves on opposite sides of the throat and carrying a pin extending into a fuel discharge nozzle tube. The control edge of the slide has a concave recess which, together with the confronting surface of the carburetor throat defines the air passage surrounding the pin and concentrates the flow of air directly over and past the pin in such a way as to thoroughly atomize the fuel and distribute it uniformly in the airstream. Another feature of the invention is a choke arrangement comprising a longitudinal air passage bypassing the throttle slide and leading to a fuel choke valve and a cross passage into the downstream portion of the carburetor throat. The air flow through this passage will draw fuel up through the valve.

A novel mounting means is provided in the slide for the upper portion of the tapered pin to provide a floating action which accommodates tolerance variations while assuring proper alignment of the pin and maintaining the close fit necessary for proper operation. An adjustable idle stop in the form of a spring-held screw coacts with the slide and is mountable on either side of the body.

The pin is tapered and has a shoulder at the deeper end of the taper which acts as an acceleraor pump, providing a spurt of fuel under conditions of rapid acceleration. The pump structure also provides support for the outboard end of the pin. A novel pin taper construction is also shown which furnishes increased atomization.
