Abstract: ABSTRACT OF THE DISCLOSURE           An electrical switch in which during a switchoff operation the switchoff current is commuted from a continuous current patch through the switch to an extinction current path which includes a pair of separable contact members one of which is located in a region of the switch housing within which a relatively low gas pressure exists, the other contact member being located within a pressure chamber in which a higher gas pressure is generated during the switchoff operation by heating the gas electrically with an auxiliary rotating arc drawn between a pair of arcing members located within the pressure chamber and which disengage during the switchoff movement.  The heated and pressurized gas within the pressure chamber is discharged through a small opening in a nozzle which is opened as the contact members separate thus blasting and extinguishing the arc formed therebetween.

Abstract: ABSTRACT OF THE DISCLOSURE       A system for reducing noise in a color video signal which utilizes frame store integration and includes a delay or storage device for storing a single television frame, a summing device for adding a fractional amplitude portion of the signal stored in the storage device to a fractional amplitude portion of the present video signal, and a chromin-ance corrector circuit for altering the chrominance component of the stored signal so as to be in the proper phase relation-ship to be summed with the chrominance component of the present video signal.  The system is operative automatically to change the fractional amplitude portion of the stored signal fed back to the summing device as a function of the difference between stored and present signals thereby to change the integration time constant of the system to accommodate for motion between the present signal and the stored frames.  The system functions as a comb filter whose tines are very narrow when there is little or no motion between the present and stored frames and which are automatically widened to allow motion to be portrayed when there is relative motion between past and present signals.

Abstract: METHOD AND APPARATUS FOR FASTENER TENSIONING       Abstract of the Disclosure A fastener tensioning method and apparatus for obtaining a desired degree of tension in a fastener.  The apparatus includes a means for applying rotation to a fastener, a means for measuring the torque applied by the means for rotating the fastener, a means for determining a rate of change of torque applied to the fastener with respect to the rate of change of rotation applied to the fastener, a means for determining a shut off condition based on the determined rate of change of torque with respect to the rate of change of rotation and a proportional rate determined amount of rotation of the fastener, and a means to shut off the means for applying rotation to the fastener in response to the shut off condition being achieved.  The embodiment of this invention described utilizes the slope of the change in torque per change in rotation gradient to predict a rotation starting point independent of the rotation that occurred in the torquing cycle up to the point of establishing a constant gradient.  In the constant slope or gradient area of the torque rotation curve, rotation is considered linearly propor-tional to the tension in the fastener.  A prescribed addi-tional rotation is applied to the fastener utilizing the threads as a micrometer device for stretching the bolt to achieve the desired tension or fastener strain level.  With appropriate system monitoring such as the total rotation, the maximum torque applied, the gradient slope, etc., the system can be adapted to inspect the fastener for applied tension as well as accurately control tension level.

Filed: 1978-04-10
Granted: 1981-07-28
Abstract: ABSTRACT OF THE DISCLOSURE The disclosure is directed to an apparatus and method for determining the bound-water-filled porosity of formations surrounding a borehole. Bound-water-filled porosity is the fraction of the formation unit volume (matrix plus fluid) which is occupied by bound water, bound water being the portion of the total water which is adsorbed or bound to, or impermeably held by, the matrix.  In one embodiment, a first quantity is obtained which is a measure of the attenuation of microwave electromagnetic energy passed through the formations of interest.  This first quantity may be, for example, the attenuation constant determined for the microwave electromagnetic energy passed through the formations.  A second quantity which is substantially proportional to the square of the first quantity is then obtained and it is indicative of the bound-water-filled porosity of the formation.  In another embodiment of the invention, a third quantity is obtained which is representative of the total porosity of the formations.  In this embodiment, a fourth quantity is generated as a function of the difference between the third quantity and the second quantity, the fourth quantity being indicative of the free fluid index of the formations.

Abstract: HYDRAULIC SYSTEM WITH UNLOADING VALVE ASSEMBLY               Abstract of the Disclosure A hydraulic system having a reservoir fed charge pump supply-ing pressurized fluid through a filter to a supply pump for direction controlled fluid devices includes an unloading valve assembly on the return passage from the devices for limiting back pressure therefrom as long as the charge pump supplies sufficient pressurized fluid for the supply pump.  The unloading valve assembly includes an unloading valve movable in response to the pressurized fluid at the connection between the supply pump and the filter to unload the return passage by connecting it to the reservoir and further to control the pressurized fluid going to the filter by connecting the charge pump to the reservoir at a predetermined maximum pressure of pressurized fluid.  As the devices require more fluid from the supply pump causing the pressure to the supply pump to drop, the unloading valve first blocks the charge pump from the reservoir and then the return passage.  After the return passage has been blocked, the pressure therein rises to activate a makeup valve provided in the unload-ing valve assembly which connects the return passage to between the charge pump and the filter to cause return fluid from the devices to feed directly to the supply pump.  The unloading valve assembly further includes a signal valve which responds to a predetermined pressure differential across the filter to provide a signal indicative of a clogged filter and to cause the unload-ing valve to connect both the return passage and the charge pump to the reservoir.
