Abstract: A compact-sized device for feeding a lengthwise oriented U.S. dollar bill, or the like, in a C-shaped feed path about a centrally located ultraviolet source, which contributes to the sterilizing of the bill. Cooperating pairs of rollers in corner locations in relation to chutes maintain proper feed control over the bill wherein the spacing of the rollers is selected so that either a leading or a trailing edge of the bill is engaged in the bight of a pair of rollers at all times, thereby subjecting the bill to a positive feed action.

Abstract: A self-holding type push switch is capable of switching over contacts by alternatively holding and releasing a slider having a heart type cam, using an engaging mechanism received in receptacle grooves of a switch case. The engaging mechanism comprises a hook rod adapted to move into and out of engagement in a recess of the heart-shaped cam and a spring plate member for movably holding the rod between portions resiliently urged together over the rod.

Abstract: A push button switch comprising a noncircular push button, a casing having a noncircular guide opening for the push button, a push button return spring, a carriage member projecting in one lateral direction from the push button and carrying a contactor facing in a transverse lateral direction and selectively engageable with contact means, a contactor spring acting in the transverse lateral direction between the carriage and the contactor and tending to cause twisting rotation of the push button, the noncircular push button and its noncircular opening tending to stabilize the push button against such twisting rotation, and an additional stabilizing member slidably backing up the carriage for taking up the force of the contactor spring and preventing such twisting rotation of the push button. The additional stabilizer member may be a slide rail on the casing or a flange on a second parallel push button, which may have a second carriage slidably backed up by a slide rail on the casing.

Abstract: A rocker switch comprises a contact spring in the shape of a loop, supported against a pivot member. The spring has a catch in the free end of the loop. The contact spring can be pivoted by means of a rocker lever into its open or closed position. The rocker lever is mounted on a roll provided with two additional cams in the form of a rocker. By means of an elastic switching arm arranged on the slide, the rocker is actuated by overrunning, thereby effecting the pivoting of the end support cam over the pivot member. This in turn yields movement of the contact springs into their open or closed positions. The contact springs may be arranged in series adjacently to each other and/or on a common axis successively to each other with their loop openings in the same or in opposing directions.

Abstract: A disconnect switch for high-voltage installations is disclosed. The switch includes a pair of hollow contacts, one of which is movable, disposed in a grounded metallic housing filled with compressed gas. A spring-loaded contact-breaking pin is provided in one of the hollow contacts. The pin is provided at its free end with a recess which is engaged in the "on" position of the switch by a ratchet device pivotally disposed in the other contact. During movement of the movable contact toward the "off" position of the switch, the contact-breaking pin remains in contact with the ratchet device. The mechanically controlled ratchet device releases the contact-breaking pin at a given position of the movable contact. The contact-breaking pin is then returned by its spring into its hollow contact with a velocity greater than that of the movable contact.

Abstract: A multiple contact arrangement for electromagnetic switchgear is disclosed. The contact arrangement comprises a movably guided contact bridge carrier which holds spring-loaded contact bridges in windows open on one side, the contact bridges being offset in the central part. The contact bridges make electrical contact with fixed contacts which are arranged essentially lined-up with the front edge of each contact bridge carrier window as viewed in the direction of motion of the contact bridge carrier. Partitions are attached to the contact bridge carrier which cooperate with switching chamber housing partitions to form enclosures for each of the contacts. The contact bridges are offset in their central part so that make or break contacts can be formed as desired by reversing the orientation of the contact bridges by 180.degree.. The contact arrangement allows a set of break contacts to be placed between two sets of make contacts.

Abstract: Electrically powered apparatus is provided with a remote primary control station from which energization of the apparatus is usually controlled, and a secondary control station, such as a jog control station, which is remote from the primary control station and close to the apparatus, from which energization of the apparatus may also be controlled. A single manual push button start control module may be mounted at either station, so that when the module is at the secondary station there is no start button at the primary station. A holding circuit provides for extended energization of the apparatus when the push button is momentarily depressed at the primary station, and there is a stop button at the primary station; while the secondary station has no holding circuit. The holding circuit is disabled when the module is mounted at the secondary station, so the apparatus cannot be energized by mounting a second identical start control module at the primary station.

Abstract: A push button actuator for an electrical switch device is disclosed which provides high tactile feedback with small button travel. Movement of the push button is resisted by a resilient column extending between the button and a force transfer device which is adapted to laterally engage the column in response to a sufficient force applied to the force transfer device through the column. The lateral engagement initiates buckling of the column which sharply reduces its load bearing capacity and causes the push button to snap to its depressed position.

The improved switch operating section includes an actuating plate disposed so as to be slidable along the inner surface of the switch housing, the actuating plate being detachably attached to the switch actuating member, to thereby allow the pushbutton, switch actuating member, supporting frame and actuating plate to be connected in series and detachable from one another so as to be integrally movable.

Abstract: This invention relates to an improved dual action switch assembly in which each of two pairs of electrical contacts is alternatively locked in open position by a tensioned locking element upon the interaction of a driving mechanism partially positioned within a frame on a slider unit. The switch assembly in a preferred form includes a base, two movable contact arms and two corresponding fixed contact brackets mounted on the base. The contact arms are mounted for pivotal rotation about mounting terminals. A biasing member, as for example a coil spring, is attached to each of the contact arms to provide a resilient force against pivoting opening movement of the contact arms. A tensioned locking element, preferably formed of two bent, over-center, leaf springs, is mounted between the slider unit and the base.

Abstract: A getter for use in a sealed contact chamber consists of a porous getter material which acts to adsorb substances which could create resistive films on electrical contacts. By disposing such a getter within the contact chamber of a switching device, such as an electromagnetic relay, molecules of, for instance, organic compounds, may be selectively and over long terms adsorbed to the getter and thus kept away from the contacts. The selective adsorption of such molecules is achieved by a porous getter material in which the majority of the pores have diameters greater than 3 nm and smaller than 100 nm, with the mean value of pore diameter ranging from about 7 nm to about 20 nm. The getter material may be substantially Al.sub.2 O.sub.3.
