Abstract: A continuously variable transmission utilizes a cam loading device with a hydraulically controlled CVT of the metal V-belt type. The cam loading device applies an axial loading force to the pulley flanges in proportion to the output torque. A hydraulic mechanism positions the pulley flanges to compensate for the limited axial movement of the cam mechanism. A preload spring and hydraulic cushion provide a necessary preload while cushioning shock from reversal of torque. The loading force on the CVT is permitted to vary with the output torque to provide improved efficiency for a full range of automotive driving conditions.

Abstract: A piezoelectric sensing element is formed from bonding two piezoelectric layers with an intermediate metallic film. The intermediate metallic film is comprised of two separate films, which were sputtered onto the inner surfaces of the respective piezoelectric layers, which are then placed in contact with each other. The combination of piezoelectric layers and film is next heated at an elevated temperature for fusing the respective sputtered alloy films so that the piezoelectric layers are bonded into a piezo-pair sensor. The layers to be joined are chamfered so that the center electrode appears as a notch on the finished piezo-pair to allow a connection to the center electrode for poling and sensing.

Abstract: A method and apparatus for measuring a dynamic effect applied to a vibrating beam accelerometer. The apparatus analyzes a pair of frequencies related to natural frequency as a function of a force applied to a vibrating beam accelerometer producing f.sub.1 and f.sub.2 ; (f.sub.1.sup.2 -f.sub.2.sup.

Abstract: A CVT combined with a gearshift mechanism to permit shifting of power flow under conditions of zero load and synchronous speed. The CVT can adjust the output speed within a gear ratio without resetting of the CVT ratio during a shift. The full speed range of the CVT is matched by two planetary drivetrains having normal and inverted characteristics and driven by two shifting gearboxes. Input power is divided into three paths to drive a central CVT and the two shifting gearboxes. The output of one of the gear-boxes is clutched to the normal input of a compound planetary drivetrain and the output of the other gearbox is clutched to the inverted input of the compound planetary. The CVT is coupled to the sun gear input of the compound planetary with the output of the compound planetary providing the output of the gear-assisted CVT. Operation occurs with either of the two clutches engaged to a respective input but not both, so that each gearbox may be shifted when its output is disengaged.

Abstract: An absolute digital clock system which is capable of counting absolute time despite the disruptive effects of a nuclear event, or other disturbance, on the electronic circuitry of the system. The clock system of the invention includes a master quartz crystal oscillator stage, and a string of counter stages connected thereto each including a binary counter for counting down from the frequency of the preceding stage to a lower frequency, and each including a crystal oscillator phase-locked with the binary counter and producing a signal at the lower frequency.

Abstract: A phase locked loop circuit employing a first edge detector consisting of an exclusive OR gate and flip flop circuit feeding by way of a NAND gate, an up counter and a second edge detector of like kind feeding also by way of a NAND gate into a down counter. Both counters feed into an added which provides a signal to a decoder representing the phase difference between the input phase and the output phase signal. The phase processing system provides positive rapid pull-in over the entire frequency range capability of the VCO, which allows narrow bandwidth loops to track rapid rates of frequency change without loss of lock and with great accuracy.

Abstract: A three-axis stellar sensor comprising a conventional stellar sensor for detecting the presence of light from a radiant body. The stellar sensor is mounted on a stable member located in a vehicle. The axis of the telescope of the sensor is parallel to a first line of sight to a first radiant body and a silvered mirror located at an angle of 45.degree. to the axis of the telescope provides a means to measure light from a second radiant body along a second line of sight 90.degree. displaced from the first line of sight. Additional means are provided to rotate and measure the mirror angle.

Abstract: A temperature compensation mechanism for a vibrating beam accelerometer comprising first and second bridge circuits. A quadrature signal is applied to the first bridge circuit containing the quartz crystal which pulls the resonant frequency of the quartz oscillator up or down depending upon the frequency shift caused by temperature variations.
