Abstract: CODE SENSING SYSTEM            Abstract of the Disclosure:          A transition code processing system which includes a record member on which is located a plurali-ty of bar code symbols, each of which comprises a data channel and a clocking channel.  The record member is inserted into a data terminal device and intermittently driven through a printing station in which a sensing member senses the data channel out of phase with the sensing of the clocking channel and generates signals in response thereto.  A circuit coupled to the sensing member will process the generated signals and transmit the processed signals to a utilization device.  Upon processing the signals representing the last bar code symbol on the record member, the circuit will generate a control signal for stopping the movement of the record member through the printing station, thereby conditioning the record member for a subsequent print-ing operation.

A toggle lever is connected to the inner wall to flex it so that a portion thereof is flexed away from the sealing rib to open a dispensing passage to an outlet in the outer wall beyond the spout lip.  A removable seal retainer insert holds the inner wall in sealed position until the value is to be used.

Abstract: MICRO-ARC WELDING/BRAZING OF METAL TO METAL   AND METAL TO CERAMIC JOINTS     ABSTRACT             Method and apparatus for micro-arc brazing and welding of metal to metal or ceramic.  The control of arc heat flux density is accomplished by controlling the ambient gas pressure and providing an argon, argon/5% hydrogen or other inert gas atmosphere.          The discharge current is controlled so as to provide an arc which is operable at 100 microamps to 20 amps.           Prior to welding or brazing, the work is cleaned by high frequency electrical discharge cleaning techniques using high energy ions from either the ambient gas or from an electrode.  By providing a small amount of DC during the high frequency discharge a "tinning" capability is established.           The welding or brazing may be formed in a closed chamber so that arc stabilization can be accomplished.

Abstract: ABSTRACT OF THE DISCLOSURE A high-speed switch usable at high voltage includes a pair of contacts movable apart along a fixed line. When the contacts are normally interconnected, at least one of them contributes to the definition of an enclosed chamber. Pressurization of the chamber by the ignition of a power cartridge therein rapidly drives the contacts apart, forming a first gap between them. The first gap is electrically insulated and is shielded from the ignition products of the cartridge. Any arc forming in the first gap is constricted and subjected to arc-extinguishing gas. When the contacts are inter-connected, a first one of them is electrically connected to a terminal. As the contacts move apart, a second gap forms between the first contact and the terminal. The second gap is electrically insulated and is shielded from the ignition products of the cartridge. A fuse may be connected in shunt with the contacts and the insulated gaps. Preferaly, the shunt connection is made after the first gap is formed, but before the second gap is formed. This permits the first gap to effect commutation of current from the switch to the fuse and the second gap to be formed after the commutation. The second gap thus experiences no or only limited arcing and remains essentially uncontaminated so that recommutation of current from the fuse to the switch is prevented.

Abstract: ABSTRACT:       Disclosed is an electron gun comprising a cathode, a first apertured anode spaced from said cathode and operated at a potential of between 5 and 30 volts positive with respect to the cathode.  The gun further comprises a second apertured anode spaced from the first anode and operating at a potential of between 100 and 400 volts positive with respect to the cathode to produce a lens field in the region between the anodes which focusses the electrons emitted from the cathode at a crossover therebetween.  The cross-section of the beam produced by the gun is determined by the size of the aperture in the second anode and the beam current may be varied by chang-ing the voltage on the first anode to thereby move the crossover closer to or further away from the second anode so that a larger or smaller portion, respectively, of the electrons in the beam passes through the aperture.         Alternatively, a beam-limiting element, separate from the second anode, may be used.
