Abstract: Abstract of the Disclosure This invention relates to a process for selectively recovering vanadium from spent catalysts which were used in hydrodesulufurization, hydrodemetallization, etc. of heavy oils until metals in said heavy oils accumulated thereon. More particularly, it relates to a process for recovering vanadium, and if desired, vanadium along with nickel from spent catalysts in such a way that said spent catalysts are chlorinated with chlorinating agent(s) at a temperature below 600°C without being subjected to calcination so as to convert almost all the vanadium compounds to vanadium tetrachloride which is recovered in the form of a gas, including the chlorination of nickel compounds to nickel chloride which can also be recovered as such by solvent extraction.

Abstract: Abstract of the Disclosure A low-profile locking cap for a threaded filler neck includes a closure member for engaging  and closing the neck, a shell providing a hand grip and including a key-actuable lock, and a race disposed for rotation between the shell and closure.  The race includes axially inwardly open-ing pockets, and the closure includes flexible pawl fingers for engaging the pockets to provide a driving connection between the closure and race which is positive in the cap removal direction and torque-limited in the cap advancing direction.  The race also includes a set of peripherally spaced, radially inwardly projecting teeth, and the shell is molded to provide a pair of flexible drive fingers for engaging the peripherally spaced and radially inwardly projecting teeth to provide a driving connection between the shell and race which is positive in the cap advancing direction and torque-limited in the cap removal direction for free ratcheting of the cap when it is in position on the filler neck and locked.  A lock-controlled blocking member is movable by the lock to a cap removal position. The blocking member engages the drive fingers, when in the cap removal position, to prevent the drive fingers from flexing out of engagement with the teeth to render the engagement between the drive fingers and teeth positive in the cap removal direction.

Abstract: A PROCESS FOR SLICING BOULES  OF SINGLE CRYSTAL MATERIAL Abstract of the Disclosure A process for slicing boules of a single crystal material such as gadolinium gallium garnet (GGG) into wafers is described. The boule is prepared, by grinding preferably, so that the longi-tudinal boule axis corresponds to the crystallographic orienta-tion axis of the boule.  The boule is then mounted in a fixture and aligned so that the common longitudinal axis and crystallo-graphic orientation axis is perpendicular to the saw blade.  The boule is then rotated while maintaining the orientation of the combined common axis and engaged against an inner diameter rotating saw blade for a time sufficient for the blade to slice through the boule and form a wafer.  The wafers obtained by this slicing process may be directly polished without the conventional lapping step to form a wafer having a surface that is substan-tially flat, parallel and defect free.

Abstract: ABSTRACT The invention relates to apparatus for analyzing electrical circuit boards.  Individual elements which have failed can be identified without disconnecting them from the circuit and testing may be done by unskilled operators by contacting a probe to a lead on an element. The probe has at least two contact elements close enough to each other to simultaneously con-tact a lead of a mounted integrated circuit, but spaced apart from each other sufficiently to permit measurement of electrical activity in the lead segment between the tips.  Circuitry is connected to the probe for measuring the voltage drop between the two tips resulting from the flow of test current through the resistance of the lead segment, which current flow is indicative of the condition of the element.

Abstract: ABSTRACT OF THE DISCLOSURE A gaseous fuel burner for enhanced flame adherence to a tile sur-face in a furnace, comprising a gas burner tube having a nozzle at its end, including a plurality of radial orifices circumferentially spaced in a transverse plane.  A cylindrical combustion air plenum is coaxial with said burner tube, and means are provided to supply combustion air to said plenum at a selected super-atmospheric pressure P1.  There is a circular concentric opening in the wall of the plenum and a short length of air tube welded to the opening, which is inserted into an opening in the furnace tile. A plurality of curved vanes are provided, and means to lead air from the pres-surized plenum through the vanes to provide a rapidly spinning air flow which moves helically along the air tube into the tile and into the furnace.  The central opening of the tile is flared in an arcuate manner.  There is suf-ficient pressure drop between the air plenum at P1 and inside of the air tube P2, after passage through the vanes, of the order of 0.8 W.C., so that a tangential air velocity of as high as 100 feet per second is possible. This rapidly spinning air volume has fuel injected into it under pressure through the radial orifices and flows into the furnace in an expanding spiral flow along the arcuate portion of the tile.  Because of the high tangential velocity of the air, gas and flame, the pressure at the face of the tile is low and the flame is held in close contact with the tile causing rapid heat transfer to the tile which then radiates into the furnace area.

Abstract: Abstract of the Disclosure A thermal switch having contacts with one contact being movably mounted on a carrier and with movement of the carrier controlled by a bimetal actuator disc.  The actuating movement is transmitted through a striker pin of molded ceramic material which is fastened in fixed relation to the carrier by a layer of adhesive of controllable thickness to establish the effective length of the striker pin.       The method of manufacturing the thermal switch embodies holding of the striker pin in fixed predetermined relation to components of the thermal switch.  During movement of the parts to this position, a mass of adhesive carried at an end of the striker pin is pressed between the end of the striker pin and the carrier to provide lateral flow thereof until said pressing is discontinued to provide a controlled thickness layer of adhesive which is then set with the parts held in a predetermined relation.  A tool used in the method comprises a disc having a central opening with a bottom wall to receive a lower part of the striker pin and hold the upper end of the striker pin oriented for movement relative to the carrier as the components are brought into said predetermined relation.

Abstract: ABSTRACT        This invention relates to an apparatus and process for writing video information in the form of a frequency modulated signal upon a video disc member and for recovering video information from the video record .  The video disc member formed by the writing apparatus is also described. The writing apparatus includes a laser as a source of a laser write beam and a write optical system for directing the stationary laser write beam to a moving video disc member.  The video disc member comprises a substrate member carrying a light responsive coating on at least one sur-face.  The write optical system focuses the beam to a small spot of light approximately one micron in diameter upon the light responsive layer.  The intensity of the focused spot is changeable under the control of a light intensity modulating assembly.  This light intensity modu-lator changes the intensity of the write laser beam with respect to a predetermined threshold intensity sufficient to form a first type of indicia in the coating.  Circuitry is described for using a triangular frequency modulator for driving the Pockels Cell driver and for obtaining a sinusoidal-shaped light modulation output signal from the linear polarizer.  The output from the linear polarizer is adjusted such that the half power point from the polar-izer equals the threshold power level of the material forming the information storage layer.  A second harmonic bias circuit is employed for removing the second harmonic intermodulation distortion of the modulated write beam.
