Abstract: Apparatus is disclosed for generating electrical pulses in response to rotation of a shaft. The apparatus incorporates an internal optical disc carried by a hub assembly attached to the operating shaft, with the hub assembly having a beveled bearing surface at one end thereof for engaging a similarly beveled surface of the apparatus housing, and biasing means for biasing the hub assembly toward said housing beveled surface to compensate for mechanical wear and to also minimize erratic movement of the optical disc. The combination of a light emitting diode and photo-transistor generate electrical signals in response to the blocking and transmitting of light through radially oriented opaque segments of the disc during rotation. The light emitting diodes and photo-transistors are retained by receptacles which snap fit within cooperating apertures of the housing.

Abstract: Sports goggles are formed with anterior and posterior frame sections each having a bow spaced from each other to define a slot to provide increased ventilation of space behind lens and particularly against the rearward surface of the lens for the elimination or reduction of fogging. The anterior frame section carries the lens at a position spaced farther than normal from the wearer's face and posterior frame section carries a nosebridge and temples. These goggles may be economically manufactured by molding lightweight material into a separate posterior frame section and a separate anterior frame section, then joining the two frame sections through tab and slot assembly.

Abstract: A thread forming screw having a helical thread and a tapered lead-in section with a polygonal cross section is formed from a conventional blank by rolling the blank between a pair of thread rolling dies having means thereon to form alternating convex lobes and concave relief areas in the frusto-conical surface of the blank. Thus, the screw may be formed with a polygonally shaped threading end without a prior working of the blank's frusto-conical surface. Curved ramp surfaces smoothly interface the lobes and concavities to allow metal in a workpiece being threaded to roll into the concavities thereby reducing the torque needed to form a thread in the workpiece.

Abstract: This invention teaches apparatus having track-like guide means adapted to be secured onto the face of a conveyor belt crosswise of the belt in the general area of a mechanical joint to be made in the belt. A carriage rides along the guide means, and supports first and second cutters used to cut a groove in the belt and to end cut the belt. Power means such as a winch is used to move the carriage along the guide means. The practiced method includes taking sequential passes of the cutter carriage to make these cuts, and taking like steps at the opposite ends of the belt span. The mechanical fastener can be received then in the matched recesses and secured to the underlying portions of the belt ends to join them together while having the fastener generally flush with the rubber overlay. The apparatus is entirely portable and particularly adapted for in-the-field repair and/or modification of existing conveyor belts.

Abstract: An agricultural implement having a primary frame on which is mounted an adjustable secondary support frame through connecting links and depth control screws enabling adjustment of the secondary support frame relative to the primary frame while maintaining the secondary support frame in generally parallel relation to the plane of the primary frame. First tools such as disk gangs are carried by the secondary support frame, while different type tools such as shank mounted earth working points and contiguous moldboards are mounted on the primary frame spaced from the first tools. Wheels mounted on the primary frame enable raising of the primary and secondary frames and associated tools for transport, and are adjustable to serve as gauge wheels for the earth working points and moldboards.

Abstract: A bit-sampling multiplexer apparatus includes two terminals, each having a transmitter portion and a receiver portion. A transmitter in one terminal multiplexes data on a plurality of incoming data channels into a serial data frame, and couples this frame across a high-speed digital data communication line to the opposite terminal. The communication line comprises a physical twisted pair cable, optical fiber, or other suitable means for transporting digital data. Two separate lines are provided to enable communication in both directions between said terminals. The transmitter portion of each terminal periodically samples each of a plurality of data channels connected thereto at a rate significantly faster than the bit rate of each such channel, to generate the serial data frame. Each transmitter may also include an edge detector for generating a signal when a state change is detected in one or more high priority data channels.

A method and apparatus are also disclosed for trimming the drawn pan and forming stacking protuberances adjacent the corners of the pan.

Abstract: Single or double-leaflet heart valves include leaflet valve members which are arcuate in cross section, preferably being essentially a portion of the wall of a circular tube. Generally spherical sectors protrude oppositely from the leaflets and are received in elongated, complementary depressions in the interior wall of the annular valve body at generally diametrically opposite locations. As the leaflets pivot between the open and closed positions, the guides move from one end of the elongated depressions to the other. Eccentric pivot axes provide for quick response of the leaflets, and their arcuate shape coupled with shifting of the axes during pivoting moves the leaflets out of the center of the valve passageway reducing resistance to the free flow of blood.
