Abstract: A polypectome snare whose loop (46) comprises a pair of electrodes (40,42) mechanically joined but electrically insulated from one another at their distal ends and adapted to be energized by a source of RF voltage for excising polyps on the inside of a body cavity is described. The polypectome snare is designed to be used with an endoscope and includes two concentric flexible plastic tubes (12,20) each having proximal and distal ends (14) and a lumen running the length thereof. At the proximal end is a hand grip which is secured to the wires leading to the bipolar electrodes with one of the wires passing through the lumen of the outermost tube and the other wire extending through the lumen of the inner tube. In this fashion, the wires remain insulated from one another over the length of the instrument and due to this same arrangement, the conductors comprising the bipolar electrodes cannot become twisted at the distal end of the implement to thereby create a short which would render the snare inoperative.

Abstract: A new form of expandable slit metal foil (10) which may be stretched into a three-dimensional metal net useful in extingui­shing surface fires, preventing explosions in fuel containers, and the like. The product is a continuous sheet of metal foil (10) with lines of slits (11) transverse to the longitudinal di­mension of the sheet (10). The sheet (10) has no unslit longi­tudinal margins resisting longitudinal stretching, and thus compact rolls of unstretched foil (10) may be transported to sites of fires and stretched into metal nets as they are un­rolled over the surface of a fire, The expanded metal net may also be formed into small ellipsoids to be filled into fuel con­tainers for the prevention of explosions. 
     The invention also includes methods and apparatus for pro­ducing the expandable metal foil (10) and the ellipsoids, and methods for extinguishing land or water surface fires and pre­venting explosions in fuel tanks.

Abstract: An integral actuator/reel lock/spring for a video cassette is described, including: (a) a lock body having a first end and a second end, an inclined opening at the first end to receive a tape player/recorder pin, lateral wings, angled grooves and a lead in for a self-centering rib in the cassette base; and (b) a spring bar connected centrally at the second end of the lock body, the spring bar including a pawl and a lower dog leg combination formed at each end. The lock body is received in the cassette base in an area defined by: (a) a first, elongated, central portion having parallel side walls, between which is formed a self-­centering rib; and (b) a pair of lateral, substantially triangular walled portions, each spaced from the central portion. The lock body fits substantially within the central portion with the wings extending above the parallel walls, the grooves resting on the parallel walls, the spring bar extending across the parallel walls, the pawls pivotably mounted against the lateral portions and the dog legs underlaying the reels. In the "locked" position, the biasing spring bar normally urges the lock body inward in the central portion. The pawls contact by ratchet action teeth formed on the circumference of each bottom reel flange. During the locked condition, the reel lock has the ability to pivot to each side of a center line of the central portion to move with shifting reels. When the cassette is placed in the player/recorder, a pin of the tape player/recorder enters the inclined opening and forces the lock body against the force of the spring arm. Only at this time does the lead-in receive the self-centering rib to direct the lock body backwardly along the center line. Also,   the spring arm becomes more curved, pulling the pawls toward the center line and out of ratchet engagement with the teeth so that the lock body enters the unlocked position.

Abstract: Mobile stations are classified into a first grouped station which is portable, and a second ungrouped station which is carried by a vehicle. A grouped station receives a part of time slots of a paging channel relating to the group which the station belongs, and an ungrouped station receives all the time slots of a paging channel. A base station having a plurality of buffer cells (1-n) relating each groups, stores the queue of the paging signals in each buffer cells, and broadcasts the content of each buffer cell in the related time slot of the paging channel. A paging signal for a grouped station is stored in the related buffer cell, and a paging signal for an ungrouped station is stored in the buffer cell which has the shortest queue. Thus, a grouped station saves battery power becasue of intermittent receive of a paging signal, while keeping short waiting time for an ungrouped station, and small call loss ratio.

Abstract: A method of producing sheets (48) of elastomeric coated cords (40) for use in the building of laminated rubber articles such as tires is disclosed. The process eliminates the use of polyethylene liners in the manufacture and storage of the sheets. Composite elastomeric sheets are produced having cords (40) on one side and an unvulcanized elastomer (44) on the other side. The tack of the unvulcanized elastomer is reduced after calendering such that the sheet can be rolled up upon itself, without the use of a liner, and unrolled such that it will self-release. The above method is especially adapted for the manufacture of strips of sheets for use as overlays in tires.
