Abstract: A system for capacitively gauging distance to an element which is not in a low impedance path to ground.  The gauging system operates to provide an indication of distance with the potential on the element at a defined, level, typically ground.  Several embodiments are presented for making this measurement.  A first operates to measure distance at periodic instances when the defined potential exists.  A second embodiment uses phase opposite excitation to produce a defined potential at the element either by specific placement of the element or through a feedback control over element potential.  The system of the present invention may be adapted for use in capacitive thickness measurement on an ungrounded or highly resistive element.

Abstract: ABSTRACT OF THE DISCLOSURE     In a well testing tool having a spring whose biasing force is supplemented by the hydrostatic pressure in the well annulus at the testing depth, a method and apparatus for isolating the spring from the pressure in the well annulus utilizing the pres-sure differential between the well annulus and the testing tool bore which exists after the formation is isolated.  An insolation valve is provided whose closing force is generated by isolating the testing tool bore from the well annulus, and then increas-ing the well annulus pressure above the hydrostatic pressure.          The pressure differential thus created is utilized to close the valve.  The opening force is generated by compressing a spring as the valve is closed.  Thus, an isolation valve is provided which is normally open and which closes only after the well annulus pressure exceeds a reference pressure trapped in the bore of the testing tool by a predetermined amount.

The operations of all conparison regis-ters are selectively controlled by means of a logic circuit.          As a result, a function signal is issued by the comparison register through a given channel in accordance with a predeter-mined program set by the switches and under the control of the logic circuit means, whenever a predetermined relationship exists between the output signals from the digital device under analysis and the value decoded on the comparison register.

Abstract: COLOR VIDEO CAMERA WITH SELECTIVELY EXPANDED SENSITIVITY     ABSTRACT OF THE DISCLOSURE         Primary color filters which also pass infrared are employed in cooperation with a broad spectral response, image sensing apparatus in providing a color video camera which has an extended range of operation at low light levels.  The image beam which reaches the image sensing apparatus is selectively controlled by a regulatable infrared filtering device in cooperation with such primary color filters.  Upon detecting a normal light level, the infrared filtering device responds by blocking infrared.  At low light levels, on the other hand, infrared blocking is negated and infrared passes through some or all of the primary color filters to augment the faint visi-ble light components which are imaged on the image sensing apparatus.

The reversely bent section was found to be weak if too thin a material were employed of that the wheel cover could shimmy when supported on the wheel face.  A struck-out rib in the center of the return bend and in the two sections provides rigidity to the securing top section of the clip and permits the clip to be made from a thinner material which will eliminate the shimmy effect which was found to occur.

Abstract: CAN OPENER LATCH FOR RELEASING          CUTTING ASSEMBLY     Abstract of the Disclosure To facilitate the cleaning of a can opener cutter, the pivoted handle on which it is mounted is arranged for easy removal.  The shaft on which the handle is pivoted has an undercut section.  A keeper edge mates with the undercut section of the shaft to restrain axial motion of the shaft without inhibiting rotational motion.  The inner end of the shaft cams the keeper aside to permit assembly.  Although a gravity system could be used, the keeper is normally spring biased towards engagement with the undercut section of the shaft.  The keeper and biasing element may constitute a sin-gle element.  When a spring biased keeper is used, the shaft has a chordal segment removed between the inner end and the undercut section.  Thus when the shaft is in a predetermined angular orientation, with respect to the keeper, the handle may be removed without camming the keeper aside.

Abstract: ABSTRACT OF THE DISCLOSURE           A unitary arrangement for quickly and effectively coating ski runners and similar planar surfaces with a heat-plasticizable, wax-type coating substance is described.  An elongated container for the plasticizable substance is resiliently and telescopically arranged within an upwardly projecting hollow flange portion of a coating-application member, and a burner nozzle is removably secured to the container and is arranged to direct a flame either against the container wall or the wall of the application member, both of which are formed from a heat-conductive material such as brass.  A downward manual pressure on the container serves to open a normally closed valve between the container and the member to complete a communication path between the interior of the container and a coating slot on the bottom of the application member, while the simultaneous activation of the nozzle will plasticize the coating composition in the container via heat conduction.  Upon a longitudinal movement of the overall assembly on the surface to be coated, the now-plasti-cized coating composition is uniformly applied to such surface through the coating slot on the bottom of the appli-cation member.
