Abstract: Several embodiments of a rotary indexing mechanism having either an angularly reciprocable or rectilinearly reciprocable input, an output rotary friction drum and a one-way drive interconnect system between the input and friction drum comprising a drive line wrapped about the friction drum having one end connected to the reciprocable input and a line tensioning spring connected between the other end of the drive line and the reciprocable input and whereby the input is adapted to be actuated in one direction to draw the drive line from the friction drum and rotate the friction drum in one angular direction and to be actuated in the reverse direction by the tension spring to pay out the drive line to the friction drum and thereby uncouple the drive line from rotating the friction drum in the reverse angular direction.

Abstract: A presettable counter operated control mechanism employing a spring lock latching arrangement for releasably locking a rotatable control member in different angularly loaded positions. A coil spring connected to the control member encircles a first drum and is selectively frictionally anchored to the drum by a latching arrangement which is releasable by the counter reaching a referenced count to releasably lock the control member at a particular angular position. Two latches provide for releasably locking the control member at two different angular positions thereof, and are tripped at two respective referenced counts, with both latches being tripped at the later reference count. Final release of the control member is operative to terminate counting operation.An interlock between the control member and the wheel presetting mechanism prevents interference with the setting of the counter wheels while the control member is locked and the counter is counting.

Abstract: A clock with a rotary drive motor having a pair of axially aligned stator subassemblies with identical molded frame parts with interfitting end portions rotatably supporting a permanent magnet rotor and take-off gears. A separate axially extending U-shaped pole piece is mounted on each frame part to provide four stator poles equiangularly spaced about the axis of the rotor, and each frame part forms a coil bobbin for winding a stator coil for the respective pole piece.

Abstract: A pulse generator is comprised of an asymmetrical magnet assembly and a Hall sensor operative for generating an electrical signal upon the application of a magnetic field thereto. The Hall sensor and magnet assembly are mounted for relative movement for the generation of a train of electrical signals in response to relative displacement therebetween. The asymmetrical multi-pole magnets in the magnet assembly have a plurality of symmetrically spaced pole pairs with each pole pair including a magnetic pole of predominant polarity occupying a substantially greater area than the pole of opposite polarity. The predominant pole is sufficiently strong to provide a salient magnetic field of essentially single polarity. a magnetizing head also is provided for producing the asymmetrical pole character of the magnet.

Abstract: A low cost resettable counting mechanism comprising an electromagnetic indexing mechanism and a counter stepped by the indexing mechanism having three-piece higher order number wheels with respective unitary molded plastic reset and drive pawl members for connecting the number wheels for counting and resetting purposes. A detent arm integrally formed with the number wheel shaft engages a recess in the counter viewing crystal to hold the countershaft against rotation during counting and the counter shaft is manually rotatable for resetting the higher order number wheels. A clapper and plastic verge of the indexing mechanism interfit to retain them in assembled relationship.

Abstract: An electromagnetic counter with a rotary counter and an electromagnetic operator for indexing the counter having a generally U-shaped core plate mounted in opposed pockets in parallel end supports of a plastic support frame, an energizing winding on one of the parallel legs of the core plate, and a pivotal actuator connected for indexing the counter having a ferromagnetic armature member positioned aside and extending transversely of the parallel legs of the core plate. A ferromagnetic insert having a preselected configuration and permeability is inserted through a slot in the support frame and press fit between the parallel legs of the core plate to provide a saturable magnetic shunt for preventing electromagnetic operation of the counter by electrical noise spikes of relatively short duration and to provide an air gap filler for reducing the incipient air gap of the electromagnet.

Abstract: A resettable electronic counter employing an integrated solid state calculator circuit element, or chip, includes counter reset circuitry for automatically resetting the counter. The calculator circuit provides timing signals and is responsive to timing signals selectively connected to an arithmetic and control section thereof for clearing a count stored in registers thereof and display means external thereto, for storing a selected count in the registers, and for cumulatively adding indexing signals to the stored count. The counter reset circuitry includes control logic and a sequence counter actuated by a reset signal to generate a series of step signals. The step signals and certain timing signals are connected to the control logic which is in turn connected to the arithmetic and control section of the calculator circuit.

Data may be entered into each BCD decade of each of two BCD decade registers of the RAM directly by BCD and entry select signals applied to the chip circuit or by push button and entry select signals applied to the chip circuit.

The settings of the converter are changed by an interlock providing an irreversible gear ratio changeover.
