Abstract: The armored cable cutter of the invention has an elongated saw carrier on which a circular saw blade is rotatable, hinged to an elongated cable carrier of U-shaped cross-section that defines a laterally opening cable receiving groove. A clamping member on the blade carrier, swingable about a trunnion axis parallel to the blade axis, has cable engaging surface portions disposed along a segment of a spiral about the trunnion axis to be at progressively increasing distances from that axis, the surface portions being configured symmetrically to the blade plane and for straddling engagement with a cable in the carrier groove. The clamping member, when swung into engagement with a cable in the groove, clamps it against one wall of the cable carrier and confines it with its diametral plane coinciding with the blade plane.

Abstract: The pavement planer of this invention is carried on the front ends of the twin lift arms of a skid-steer front end loader. It has a drum with radially projecting picks, confined to rotation in a box-like housing that is open at its bottom and is supported at its front center on a heightwise adjustable roller. Secured to the lift arms, spanning the distance between them, is an upright plate-like frame member that rides on a roller on each of its ends. The housing is so connected to the frame member as to be laterally adjustable relative to it and also tiltingly adjustable about a fore-and-aft extending axis. Both of those adjustments are effected by a single hydraulic cylinder jack connected between the housing and the upright frame member. In use, a down load on the lift arms imposes part of the weight of the carrying vehicle onto the pavement planer, to be supported by the three mentioned rollers.

Abstract: A sight for an anti-aircraft gun, which is manually aimed, comprises a ranging unit, a gun-fixed aiming unit and a calculating unit, preferably a computer. The ranging unit comprises means for optical aiming at the target, and devices for determination of the range, the angular rate in elevation and azimuth, and elevation. The devices emit measured value signals to the means for optical aiming at the target, which means is settable in elevation and azimuth in relationship to the firing direction of the anti-aircraft gun. The calculating unit controls, guided by said received signals and information given about the velocity of the fired projectile and the prevailing wind vector, the second optical means in such a way that when the operator aims through same at the target by setting the barrel in elevation and azimuth, the offset and lead angles of the barrel are such that a fired projectile hits the target.

Abstract: In a glass washing machine having a glass carrier rotatable on an upright axis, half of the carrier is always in an access zone where glasses can be loaded onto the carrier and removed from it, the other half in a cleansing zone where detergent solution is discharged from a first set of spray nozzles and germicidal rinsing solution is discharged from a second set of nozzles. Upon actuation of a pushbutton switch, the carrier rotates through 180.degree., always in the same direction, then stops until the switch is again actuatd. Liquids are discharged from all nozzles while the carrier rotates. Detergent solution is recirculated, but fresh detergent solution is introduced during a predetermined portion of each period of carrier rotation.

Abstract: In normal washing operation of the beverage glass washer of the invention, detergent solution discharged from a set of washing nozzles is collected in a tank from which a recirculation pump withdraws it and delivers it back to those nozzles for redischarge; and rinsing liquid from another source is delivered to a set of rinsing nozzles for discharge from them. For cleaning and deliming all nozzles, the tank is filled with a cleaning solution and the two sets of nozzles are connected, either by opening a normally closed solenoid valve in a permanent connection between the two sets of nozzles or by slipping opposite ends of a suitably sized hose over a cylindrical nozzle body of each set. The recirculation pump then flushes the solution from the tank through all nozzles of both sets.

Abstract: In the disclosed glass washing machine each spray curtain comprises a vertically slitted sheet of supple plastic and a similarly slitted guard sheet of a stiffer but flexible smooth-surface plastic. The guard sheet extends down through about the upper half of the height of the supple sheet and overlies its side from which glasses approach it, prolonging the life of the supple sheet by decreasing rubbing and sharp flexing due to passing glasses. A grid of vertical slats closely underlies the top wall in each cleansing zone, causing upwardly sprayed liquid to fall from it in numerous uniformly distributed streams that are effective in cleansing exterior surfaces of glasses. Each spray nozzle assembly is removable without tools by loosening one wing nut and pulling out of the assembly a male fitting on a hose that communicates the assembly with another part of the machine.

Abstract: In the glass washer of this invention, a linear conveyor carries glasses successively through a prewash, a detergent wash and a germicidal rinse. Once discharged from rinsing nozzles, rinsing liquid is collected in a prewash tank from which it is pumped exclusively to other nozzles that provide the prewash. Detergent solution discharged from washing nozzles is collected in a wash tank and recycled back to the washing nozzles. Hot water and detergent chemical are fed into the wash tank at predetermined rates whenever the machine operates, to provide a makeup detergent solution and some overflow from the wash tank to the prewash tank. Novel screening means ensure against entry of foreign matter into the nozzles. Novel control means cause the machine to operate with its conveyor almost always fully loaded, for economical utilization of water, chemicals and current.

Abstract: A table supports a cardboard file unit body as it is manually slid edgewise forwardly, engaged against a fixed but adjustable side edge guide, into engagement with a fore-and-aft movable front edge guide and an air microswitch thereon that actuates a punch mechanism. After punch operation, the front edge guide moves forward, bringing the punched portion of the body between the wings of a metal tab waiting at a peening station. Arrival of the front edge guide at its forward position trips another air microswitch to actuate a tab peening mechanism. The tabbed body is then manually withdrawn rearwardly and a new tab is automatically fed rearward to the peening station from a stack of tabs in front of that station. The punching and peening mechanisms, front edge guide and tab feed slider are actuated pneumatically.

Abstract: The invention relates to a card-like information carrier readable with RF waves and having resonant devices at spaced intervals across its face that are tuned to different resonant frequencies, an item of information being encoded in the pattern of those frequencies. Each device comprises a dielectric sheet having a deposit of conductive material overlying each of its surfaces. At least one deposit has a spiral slit that defines in it a spiral inductance coil. Each deposit has a capacitance region opposing a like capacitance region of the other and having substantial extension in directions along and away from the slit. Each device can be returned to a predetermined higher resonant frequency by punching through the carrier to reduce areas of opposing capacitance regions of the device, or it can be made non-resonant by punching through all turns of its coil.

Abstract: An impeller is mounted above the top wall of the housing of a mower carried by a riding vehicle, near the side of the mower at which it has its clipping outlet. The rotor of the impeller rotates on a vertical axis that is between the clipping outlet and the vertical axis of the mower blade nearest that outlet and is driven by a belt engaging a pulley on the spindle for that blade. Flat paddle-like blades of the rotor have a portion of their orbit in an upwardly and rearwardly extending passage defined by the front portion of a clipping duct that communicates the mower clipping outlet with a receptacle at the rear of the vehicle. The impeller draws air and clippings out of the mower housing and propels them rearward through the duct.

Abstract: In the self-releasing pawl and ratchet mechanism of this invention, for controlling positions of adjustment of a seat element that is movable relative to a frame element, one member of the pawl-ratchet pair is fixed to one of those elements, the other member is confined to movement relative to the other element in directions transverse to the directions of adjustment of the seat element. A latch for locking the pawl and ratchet members out of engagement with one another is carried by the element that carries the movable member of the pawl-ratchet pair and is actuated in the adjustment directions, between latching and release positions, by a lost motion connection with the other element. In its release position the latch is disengaged from the movable member of the pawl-ratchet pair. In its latching position, wherein it is releasably retained, as by friction, the latch holds that movable member in a ratchet disengaged position.

In an open position the three panels, in coplanar relationship, are disposed edgewise upright, serving as a rear wall of the bottle trough and vertically slidably confined in channels along the rear edges of the bottle trough end walls. The three panels can be raised and swung forward to a closed position in which the medial panel is horizontal and overlies the tops of panels in the trough and the other two extend down from it to close the front and rear of the trough.

Abstract: A control device for producing electrical signals which correspond to manual movements of a stick part and which are used for adjustment of a controlled element has a relatively stationary body part with a hand supporting surface and a stick projecting outward from that surface to be embraced by an operator's hand. The stick comprises a laterally swingable outer stick part end-to-end with an inner stick part fixed to the body. A rod-like spring element in a chamber in the stick has an end portion fixed to each stick part to swingably connect the outer stick part of the inner one and bias the outer one to a neutral position. A signal emitting device in the chamber is mounted alongside the spring element and is operatively connected with it.

Abstract: In a valve assembly receivable in an outwardly projecting neck in a keg, for normally sealing the keg and for cooperation with a detachable coupler by which the keg is tapped, the cylindrical spring retainer of the assembly has at its axially inner end deflector surfaces so liquid flowing inward along that cylindrical wall during filling of the keg through the gas passage of the valve assembly is deflected radially across the inner end edge of that wall as a sheet-like jet. This prevents upward spray out of the annular space between the siphon tube and the spring retainer, thus preventing overcarbonation, excessive foaming and underfilling of the keg.

Abstract: A mounting device for a helmet wherein a hook section to be fixed on a wall surface for holding a circumferential part of a helmet wearing opening has a transverse bar. The transverse bar projects to the right and left sides of the hook section at a location with a predetermined space from the wall surface, and is long enough to abut on the circumferential part of the helmet wearing opening in case of hanging the wearing opening on said hook.

Abstract: A holder for workpieces to be coated is bent from a single piece of stiff but springy wire. A medial portion of the piece of wire defines two clamping arms that are connected at their front ends by a spring coil; and one end portion of the wire defines a mounting portion in the form of a loop connected to the rear end of one clamping arm; and the other end portion of the wire defines a pair of stabilizing wings, one of which is U-shaped with legs respectively connected to the rear end of the other clamping arm and to the other stabilizing wing. The holder is detachably connected to a carrier by means of a U-shaped supporting member having apertured lugs projecting forward from a central body. Opposite portions of the loop project through the apertures in the lugs.

Abstract: The automatic random reset torque limiter of the invention, connected between the crushing head of a gyratory crusher and its one-way anti-spin clutch, comprises a carrier element and a coaxial detent element that have end surfaces opposing one another across a small gap. The carrier has wells opening to its end surface that are equidistant from its axis and are uniformly spaced from one another. The detent element has hemispherical cavities in its end surface, one for each well, each alignable with a well. In each well is a coiled compression spring and a ball. The spring normally holds the ball engaged in a cavity but allows it to ride out of the cavity and roll on the detent element end surface while excessive torque persists.
