A gel electrolyte can have high proton conductivity even at conditions of no humidity and high temperatures and can have increased mechanical strength. The gel electrolyte can include an acid and a matrix polymer capable of being swollen by the acid. The matrix polymer can be a polyparabanic acid or a derivative thereof.

The device comprises a support (4, 8, 9) fastened by gripping to engagement surfaces (14, 15) of a weapon (1) to which there is attached, by articulation around a hinge (5), a container (6) which in a swung-down bottom position covers the loading handle (2) and the window (3) for the ejection of the cases of the cartridges fired. The container (6) has an inner case-retention wall (13, 17) rising up to the window (3). A system for the immobilizing of the container (6) by ratchet (10, 11, 12) in t...

A deck of thirty-six playing cards representing every roll combination of two six-sided dice. Each card displays the two dice on the face of each card in different color so as to distinguish every possible combination of the two dice. A corresponding game using this deck of cards for more than one players to achieve a winning suit of four cards of the same numerical total, containing the same dice, or of a specific orientation of high cards or low cards.

A rifle cartridge magazine loader which allows loading rimmed cartridges in end-to-end orientation directly into a rifle or similar magazine in nose up, nose down or any other orientation necessitated by the design or configuration of the magazine. The loader has a slot formed by two elongated members or strips which retain or suspend the cartridges by the rims. A portion of the slot communicates with a reservoir for bulk storage of the cartridges from which the cartridges pass through the slot ...

An anti-static switch lock wherein a terminal assembly having the desired configuration of rotor and contacts is secured to one end of a hub. The other end of the hub has an inboard lipped boss forming, in cooperation with the hub end, a circumscribed radial groove. A keylock assembly includes a barrel, one end of which has a chamber to receive the boss of the hub, and a key operated, rotatable plug. The hub, having the terminal assembly attached to one end, is positioned such that the groove is...

Cylindrical bearing pads are insertable into bearing pad recesses formed in a receiving surface of a bearing pad retainer in a load-carrying structure. The bearing pads have an insertion end which is fixed into the bearing pad recess by brazing or by interference fitting and a bearing end which projects from the receiving surface and terminates in a bearing face. The bearing face has a periphery which encircles the bearing face and an indentation having a perimeter formed centrally in the bearin...

Solid sodium chloride is incorporated into a sodium chloride-saturated brine containing dissolved matter, other than sodium chloride, to be concentrated. The temperature of the system is reduced to within the range from about 0.degree. C. to about -21.degree. C. to form sodium chloride dihydrate. The dihydrate is separated from the aqueous system thereby increasing the concentration of the other dissolved matter relative to the remaining liquid phase. The process is particularly useful for conce...

An electrical switch of dual in-line package type which includes a switch casing having a housing fitting over a base onto which contact leads forming switch sections of the switch are molded, actuators movably disposed in the corresponding switching sections for selectively connecting and disconnecting the contact leads, and a dust cover to fit over the housing. Each of the actuators has an actuating knob extending through the housing for moving the actuators between first and second positions ...

A new ventilator for spaces under slanted roofs or attics such as gable, hip and shed roof types; a ventilator using an elongate duct typically positioned between adjacent rafters under a roof, the duct inlet spaced downwardly somewhat from the ridge, the duct outlet discharging through an opening in the roof surface spaced further down from the ridge; the duct outlet configured to drain water from itself and the duct as well as protectable from winds, snow, hail, birds and the like. A like new ...

A transistor arrangement having a relatively low charge storage period including an N.P.N. transistor having the base thereof connected to the emitter of a P.N.P. transistor and to an input terminal, the collector thereof connected to the base of the P.N.P. transistor and to an electrical supply terminal, and the emitter thereof connected to the collector of the P.N.P. transistor and to another electrical supply terminal.
