Abstract: An improved binding strap fastener for attaching crampons (mounting climbing spikes) to mountain climbing boots includes a lever assembly and a retaining clip for retaining the lever assembly in a fastened position. The lever assembly includes a rigid, curved lever plate riveted to a portion of a binding strap. A leading end of the lever assembly is inserted through a "D-ring" attached to a connecting eyelet of the crampons and is forced against the D-ring to tighten the binding strap to a predetermined tension by rotating the lever assembly approximately 180 degrees. The lever assembly then is slid beneath the retaining clip to retain the lever assembly in its fastened configuration. The operations of fastening and unfastening the binding strap can be easily accomplished by a mountain climber wearing heavy mittens without the necessity of removing the mittens from his or her hands.

Abstract: The invention provides a novel method of formation and structure of a slitted strip of metal, such a lead, which is to be expanded into a reticulated configuration. As applied to a battery plate, the invention contemplates the formation of a continuous strip of a lead or lead alloy material wherein the central portion of the strip which is to form the unexpanded current collecting top header portions of the finished battery plates is provided with a plurality of longitudinally extending punched apertures extending along the edge of the solid central portion and separating the solid central portion from slitted portions of the strip which are subsequentially expanded to form a reticulated grid. The formation of the continuous lead strip in such fashion substantially minimizes the "gull-wing" effect produced by the subsequent expansion of the slitted portions of the lead sheet.

Abstract: A tube of ceramic dielectric material having inner and outer electrodes formed thereon is immersed in an alcohol solution of rosin to form a rosin film over the entire exposed surfaces thereof. A pair of metal caps, each having a plurality of circumferentially spaced inward projections and a thin solder layer covering at least each inward projection, are then pressed onto the opposite ends of the ceramic tube, thereby embedding the inward projections of each metal cap in one of the electrodes. The solder layer on each metal cap projection is then melted to establish firm mechanical and electrical contact between electrodes and metal caps. Semiflexible, hermetic sealing joints are then formed at least between electrodes and metal caps by applying an insulating paint while the ceramic tube and metal caps are being heated to partly evacuate the interior thereof. Finally, an external covering comprising one or more insulating layers is formed at least over the sealing joints and a region therebetween.

The box halves are mounted in abutting relation about a pair of parallel wires (11 and 12), and then heat fusible metal (46 and 47) is deposited in the aligned slots to lock the box halves together while bonding the wires (11 and 12) to opposite ends of the capacitor blank (10). When assembled, the boxed capacitor with the laterally extending leads may be readily machine inserted or otherwise assembled in a circuit module, such as a printed circuit board.

Abstract: The removal of so-called zip-tape from reclaim tobacco is achieved by use of an elongate vibratory conveyor having grooves extending longitudinally therewith and of longitudinal depth profile preselected from groove-containment of the reclaim tobacco, except for the zip-tape content thereof. Rollers having surface affinity for the zip-tape are arranged in overlying relation to the conveyor surface and groove rises, and are disposed in acute angle relation with the conveyor feed direction. The rollers are supported for joint movement with the conveyor so as to be maintained in fixed relation to the conveyor surface during vibration. Zip-tape encountered by the surfaces of the rollers is withdrawn from the conveyor grooves and is displaced successively transversely of the conveyor for collection aside the conveyor.

Abstract: A method of assembling progressing cavity pump of the Moineau type having a helically externally threaded rotor coacting with an internally helically threaded stator. In a Moineau pump where the pump casing is a singular tubular unit, the stator is normally bonded to the inside of a tubular housing with an adhesive. When such pumps are used to pump a corrosive fluid, such as caustic soda, the adhesive can be attached and the stator thus freed to rotate. To prevent the stator from rotating, studs are driven through the housing and into the stator. The location of these studs can be pre-marked by use of a suitable template. Also, the driven studs can be welded to the housing to prevent leakage or loosening.
