Abstract: A TECHNIOUE AND A TORCH FOR FABRICATING    SINGLE MODE LIGHTGUIDE SOOT-FORMS            Abstract This invention concerns with a Vapor-phase Axial Deposition (VAD) process.  To form small diameter cores for single mode lightguide preforms, a soot stream, formed by a torch comprised of a plurality of concentrically mounted, spaced, glass tubes through which reactants and combustible materials are passed, is confined radially by a confining shield gas so as to reduce the crossection of the soot stream at least in the vicinity of a soot form being grown. In a preferred embodiment the confining is effected by means of a tapered shroud mounted about the end of the torch and a shield gas directed along the inner surface thereof to confine and direct the gases and reactants to the surface of the soot form.

Abstract: ABSTRACT OF THE DISCLOSURE:          Apparatus so constructed that narrow can bodies having an internal diameter of 52 mm for example can be produced from rounded blanks by welding the edges of the blanks.  The supply of welding current to the electrode roller is effected through copper caps, a clamping member, contact members disposed at each side thereof, contact jaws silver contact segments and peripheral surfaces of broad hubs which are provided on the electrode roller.   The contact jaws engage round the hubs of the electrode roller at both sides, above and below, as a result of which a large area for the transmission of current and a low specific contact pressure result.  The hub surfaces, which form the actual contact  surfaces of  the electrode roller,  are continuously lubricated through felt lubricating segments. The contact pressure of the contact jaws can be adjusted in a simple manner by means of a screw.  The whole apparatus and particularly the electrode roller are intensively cooled internally by a special cooling device.

Abstract: ABSTRACT OF THE DISCLOSURE        Fluid is automatically removed from a gas well by providing  tubing  in the production casing which tubing  is continually vented of a small quantity of gas causing liquid level to rise in the tubing.  The liquid is trapped in the tubing by for example, a one-way check valve.  The reduced gas pressure in the tubing signals a differential pressure switch to open a switching valve, which connects the casing to  an  actuator.   The  actuator  opens  a  tubing  production valve,  whereupon a drift  in  the  tubing pushes  the  liquid upwardly  through  the  production  valve.   The drift  then returns to a seat above the tubing check valve, so that the cycle can be repeated when the liquid level again rises in the casing.

Abstract: Abstract of the Disclosure When an electronic card is inserted into the device, a first reject plate is pressed to elongate first and second coil springs to anchor the card.  When no writing or reading ROM and RAM of the card, electric current instantaneously flows through a solenoid to cause a stopper stopping a second reject plate to rotate through a slight angle so as to disengage the stopper from a front end of the second reject plate. As a result, the second reject plate is depressed by the second coil spring.  At the same time, a reject arm provided on the second reject plate moves a reject oblique surface of a card latch to move the card latch through a slight angle to lower a card guide, so that the card is pushed by the first coil spring out of the device.  In this manner, the card is not pushed out during writing or reading and hence contents of the card are not damaged.  A solenoid requires only a force for moving the  stopper through a small distance. The small solenoid and a little power are sufficient to operate the device.  As the card is pushed out by the first coil a sufficient pushing distance is obtained, so that the device can be used for many years without fatigue of the device.

Abstract: TOUCH PANEL SYSTEM                Abstract of Disclosure A touch panel has panel scanning signals selectively applied to the four sides of a touch sensing surface of the panel so as to establish alternating current voltage gradients in desired directions across the touch sensing surface.  When the panel is touched, touch signals or currents result and are utilized by a touch location circuit in determining the location of touch.  The impedance touch current resulting from a user's touch may also be determined and used.  The touch panel circuit automatically compensates for changes in impedance touch current, such as result when users touch the panel with ungloved and gloved fingers.  An analog multiplier is included in the touch location circuit to improve noise rejection.  Auto nulling and automatic frequency adjustment is included in the touch panel device, together with overcurrent protection circuitry.
