Abstract: POWER SUPPLY AND CONTROL CIRCUIT FOR SERIES CONNECTED CONTROLLER                      Abstract of Disclosure A control circuit for a power switch like a triac to be connected in series with a load device, at a situs where only one AC power conductor and a conductor extending to the load device is available, is energized from a DC power supply energized from these conductors.  The power supply includes at least one rectifier con-nected in series with a capacitor, the terminals of which consti-tute the DC output terminal of the DC power supply, an impedance of much greater resistance than that of the load device and through which the capacitor is charged when the triac is in its non-con-ductive mode, and a normally non-conductive triggerable low imped-ance threshold device shunting the high impedance and triggered momentarily into conduction as the applied AC voltage goes through zero when the triac is to be in its conductive mode.  Current flow through this threshold device triggers the power switch into con-duction a short interval after passage of this voltage through zero.  The capacitor charges only during each such short interval it takes to initiate. conduction of the power switch.

Abstract: Oil Cooled Piston Abstract Substantial heat is generated at the crown portion of a piston.  Cooling fluid has been directed to cavities in the underside of the crown.  However, at critical points of the piston cycle, the fluid drains from the cavities due to the forces of gravity.  An oil cooled piston is provided which includes a fluid trap adjacent the crown.  Some of the cooling fluid is trapped as it drains and is retained to enhance cooling of the crown. The fluid trap includes a slot permitting a jet spray of lubricating oil to be directed past the trap to the cavities adjacent the underside of the crown.

Abstract: Abstract A tape-applying apparatus (10) is advanced toward a body (15) upon which a strip of tape (16) is to be applied to urge a plurality of stitching rollers (72,74) against the body (15).  Further advancing of the apparatus (10) will move an applicator roller (42) and the end of the tape (16) into engagement with the body (15).  As the body (15) is moved past the tape-applying apparatus (10), the tape (16) is pulled over the applicator roller (42) and is stitched to the body (15) by the stitching rollers (72,74).  When sufficient tape (16) has been applied, the housing (20) of the tape-applying apparatus (10) is urged away from the body (15) which moves the applicator roller (42) out of contact with the body (15).  A brake apparatus (94) on the housing (20) is activated by a cam recess (80) on the holders (50) for some of the stitching rollers (72).  The brake apparatus (94) engages the applicator roller (42) to arrest further feeding of tape (16) to the body (15).  Continued rotation of the body (15) with some of the stitching rollers (72) in contact therewith will stretch the tape (16) between the applicator roller (42) and the stitching rollers (72) until the tape (16) is severed.  The free end of the tape (16) is left in position on the applicator roller (42) ready for the next application to the same or a different body (15).

Abstract: PROTECTIVE CIRCUITS FOR CONVERTER-SUPPLIED D.C. MOTOR     ABSTRACT OF THE DISCLOSURE    A d.c. motor whose armature is supplied from an a.c. power source through an a.c./d.c. thyristor converter and is subject to damaging commutator flash-over, as from loss of a.c. voltage during regeneration is provided with a protective circuit which includes a normally charged capacitor and a diverter resistor which are connectable across the converter and motor armature, respectively, by SCR means in response to a fault condition such as either predetermined high output current from the converter (i.e., indicative of high armature current) or excess a.c. input current to the converter.  Connection of the capacitor across the converter and its discharge instantaneously and forcibly but temporarily blocks current flow from the converter thyristors to the motor armature.  Connection of the diverter resistor across the motor armature absorbs energy generated thereby and reduces armature current to prevent commutator flash-over while other controls responsive to the fault condition permanently switch off the converter thyristors and set a brake to stop armature rotation.

Abstract: ABSTRACT           The bladder has at least a portion of its outer surface comprrising a fabric layer of cords partially embedded therein so that such cords project slightly above the rubber surface.  The article is manufactured by calendering a fabric layer of cords on one side only with a coating of uncured and unvulcanized rubber, applying the layer to the bladder material with the rubber coated surface in contact therewith, and heating the article so formed to cure the rubber coating.  The curing causes some of the rubber coating to flow between and over the outside surfaces of the cords. This excess rubber is removed by abrading the article so as to expose the cords.  The abrading removes some of the cured rubber between the cords so that the cords project slightly above the surface of the rubber substrate.

Abstract: SUPERCONDUCTING SWITCH AND AMPLIFIED DEVICE          ABSTRACT          An amplifying or switching superconductive device is described whose current-voltage characteristic is drastically altered by heavy injection of excess energetic quasi-particles.  In this device, the superconducting bandgap of a superconducting layer is greatly altered by overinjection of energetic quasi-particles so that the bandgap changes greatly with respect to its thermal equilibrium value, and in most cases is made to vanish.  In a preferred embodiment, a three electrode device is fabricated where at least one of the electrodes is a super-conductor.  Tunnel barriers are located between the electrodes.  A first tunnel junction is used to heavily inject energetic quasi-particles into the superconducting electrode to change its super-conducting bandgap drastically.  In turn, this greatly modifies the current-voltage characteristics of the second tunnel junction.  This device can be used to provide logic circuits, or as an amplifier, and has an output sufficiently large that it can drive other similar devices.

Abstract: Abstract:    The invention provides length and temperature mea-suring apparatus for tank installations, by means of which the depth of fluid in a tank can be conveniently and accurately measured.  The apparatus has a measuring tube located in the tank and a float element surrounding the tube.  The float causes a slider within the tube to follow its movements, e.g. by magnetic means.  The slider has a sliding contact which engages at least one resist-ance element located longitudinally within the tube.  A reference voltage is applied to the resistance element and the partial voltage determined by the position of the sliding contact on the resistance element is measured. From this, the position of the slider (and hence the fluid level) can be determined.  If the partial resistance is also measured, this provides an indication of the average temperature of the resistance element below the fluid level, since the temperature can be calculated from the determined position of the slider and information known about the resistance material.

Abstract: Case 3565 DIFFERENTIAL CHECKING HEAD     Abstract of the Disclosure A differential checking head for checking tooth-to-tooth spacing of evenly spaced toothed gears or for checking lead variations of helical gears is disclosed. The checking head includes a pair of sensing fingers which have contact portions that touch gear profiles at predetermined test points.          One of the sensing fingers is mounted on an arm which is pivoted in a fixed frame and which carries a moveable sensor actuator.          The other sensing finger is mounted on a second arm which is also pivoted on the fixed frame and which carries a moveable sensing element which engages the actuator that is secured to the first arm. Both of the sensing arms are returned to their initial positions by return springs; and a second sensor, or limit switch, may be actuated by the actuator that controls the first sensor. The checking head provides a differential reading dependent upon the relative motion of the two sensing arms.          This reading occurs at a very slow rate even though both of the fingers may move over the gear being sensed at a fast rate.          In this manner, a very slow and accurate minimum reading may be obtained which can be easily read or recorded.
