Abstract: A non-involute gear used in a gear pair. A first gear has a plurality of radially extending, circumferentially spaced teeth, each with a generally cylindrical, arcuate shaped end surface. A second gear has a plurality of spaced, non-involute shaped teeth. Each tooth of the second gear is formed with opposed base faces disposed at an identical radius. A pair of flats extend in parallel from the ends of each circular base face and terminate in inwardly extending, end portions extending from the flats to the top land of each gear tooth. A tooth space is formed between two adjacent non-involute gear teeth having a semi-circular base portion formed by the opposed circular base faces of two adjacent gear teeth and two parallel flat portions formed by the pair of parallel flats extending from the semi-circular base portion which combine to form a generally U-shaped space for receiving a gear tooth on the first gear.

Abstract: A collapsible steering shaft apparatus includes first and second telescopingly arranged steering shaft members. A plurality of longitudinally extending projections are formed in one of the steering shaft members and engage a plurality of longitudinally extending grooves formed in the other steering shaft member. The mating projections and grooves join the steering shaft members together for longitudinal sliding movement under external forces exerted on the steering shaft apparatus. The mating projections and grooves also prevent rotation of the two steering shaft members relative to each other and insure that the two steering shaft member rotate together as a unit without backlash upon rotation of the vehicle steering wheel. A method of forming the projections and grooves in the tubular steering shaft members is also disclosed.

Abstract: A hollow, tubular steering column jacket surrounds a hollow, tubular steering column shaft. First and second brackets are fitted into the first and second ends of the jacket for mounting the jacket to the stationary structure of a vehicle at one end and to receive a steering column switch assembly and a steering wheel at another end. A third bracket may be mounted intermediate the first and second ends of the jacket and to the vehicle for providing selective pivoting of the jacket with respect to the first end of the jacket. The steering column shaft has an integrally formed yoke at one end. The opposite end of the steering column shaft is formed for attachment to a vehicle steering wheel.

Abstract: An improved deck lid lock with remote release for motor vehicles. The deck lid lock employs a solenoid operated rotatable armature which acts directly on a leg of a rotatable latch plate which engages a lock bar. On energization of the solenoid, the armature is attracted to the solenoid causing it to disengage the latch plate so that the deck lid may be opened. When the deck lid is closed, the lock bar is engaged by the latch plate which is returned to its normal latched position in engagement with the armature. The deck lid lock further includes a rotatable key cam which acts on the armature to enable release of the deck lid through conventional external key actuation.

Abstract: An electrically controlled transmission shift interlock device. The device provides interlock capability by locking the pivotable shift actuating lever which is operatively associated with the transmission. A transmission mounted solenoid is provided having a moving armature coupled to a locking member which, when energized, positions the locking member into interlocking engagement within an engaging notch provided in the shift actuating lever. The device includes means for proper alignment of the interlocking components during installation of the interlock device onto the transmission. One alternate embodiment further provides means for having interlocking capabilities at more than one gear shift lever position. Another embodiment causes the transmission actuating lever to lock when the solenoid is de-energized and is movable upon energization.

Abstract: A variable force solenoid valve assembly is provided for use in an automatic transmission controller for controllably reducing a fluid inlet pressure to a desired outlet control pressure. The invention includes a variable force solenoid assembly secured to a valve body assembly. The valve body assembly includes a spool valve having three radially extending lands which translates within a valve body central bore in response to movement of an armature assembly provided in the solenoid assembly. Movement of the spool valve generates first and second flow restriction for controllably regulating the reduction of inlet pressure to control pressure. In addition, various improvements in spool valve design are described including a design which provides positive damping of the spool valve so as to attenuate "self-excited" oscillation thereof.

Abstract: A pressure switch having a ball valve or contact mounted in an internal chamber to move in response to predetermined relatively high and relatively low fluid pressures in an inlet that opens into the chamber to make or break an electrical circuit through the switch and that incorporates a one-piece sealing element that is constantly exposed to the fluid pressure and is uniquely formed and cooperative with the ball contact and with the walls of the chamber to prevent leakage of the fluid from the chamber effectively without significantly interfering with free unobstructive movement of the ball contact in use.

Abstract: An electrical pressure switch that can be readily adapted for either normally open or normally closed operation and that has opposed annular seats, a movable contact and ball valve movable between and individually engageable with the seats, and an O-ring uniquely associated with the ball valve and a related sealing surface in seated, unseated and all intermediate positions of the valve to maintain an effective seal at all times against fluid pressure to which the switch is connected.

Abstract: A solenoid having a coil that includes the usual bobbin or spool, winding and armature in combination with a flux collector that is uniquely formed and associated with the coil bobbin and with the armature to maintain essentially precise concentricity between the flux collector and the armature and the intervening air gap of a uniform minimum width dimension so as to minimize the size of the coil and loss of armature power in use while at the same time assuring an adequate and reliable operating force in the armature.

Abstract: A computer controlled turbo boost valve for internal combustion engines of the type having a turbo charger and a turbo charger feedback line, the valve having a valve element actuated by an internally mounted solenoid which is adapted to be connected to the computer, the valve having a valve element that is operable to regulate bypass flow of exhaust gases from the feedback line and that is mounted so as to be rapidly responsive to energization and deenergization of the solenoid and to be minimally affected by flow of exhaust gases into and through the valve, the components of the valve being uniquely combined and correlated, and the actuator for the valve element in particular being uniquely formed to provide for a high degree of quality control under mass production conditions of manufacture.

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 individual metallic, electrical conductor is terminated by heating one end thereof to form an enlarged molten mass, followed by cooling and subsequent shaping of the mass to form a terminal. Multiple conductors are spliced by heating adjacent ends thereof to form an enlarged, common molten mass at the end of each conductor. Alternatively, adjacent ends of multiple metallic conductors may be spliced by heating the ends thereof to form a molten mass at the end of each conductor followed by plunging the molten masses into one another.
