Abstract: ABSTRACT OF THE DISCLOSURE           A flexible hinge-pin for coupling two complementary rows of fastening staples on the opposite ends of a closed-loop conveyor belt or the like comprises a flexible central core such as a steel cable.  The core is surrounded successively by an intermediate plastic sheath and a tubular outer jacket formed by twisting one or a number of strands of wire, either in the same direction of twist as the core or in the opposite direction.  The intermediate sheath can be of plastic material filled with grease which is capable of flowing under the action of the relative movements of the hinge-pin components at the time of flexural deformation of the pin in order to ensure that a fraction of the grease spreads over the surface of the pin.

Abstract: Abstract of the Disclosure A fiber optic multiplexer/demultiplexer inclu-des a serial transmitter encoder for encoding an 8-bit parallel byte into a serial data stream applied to a fiber optic coupler.  A pair of 4-bit latches are alter-nately clocked to sample four parallel format digital signals to form a byte for loading into the encoder. The serial receiver decoder receives a serial data stream from another fiber optic coupler and converts the data stream to a parallel 8-bit byte.  A 4-bit multiplexer is provided for demultiplexing the byte one nibble at a time down to form parallel format digital signals.  An alternate embodiment calls for the omission of the 4-bit latches and multiplexer such that 8 signals may be multiplexed.

Abstract: INDICATING POSITIONS                        ABSTRACT  Typical apparatus as shown in Figures 1 and 12 for indicating the relative positions in a given direction between a reference point (24,59) and a test point (29,68) spaced therefrom and movable relative thereto is useful for measurement of the magnitude and direction of static or dynamic torque in a shaft (8).  Overlapping transparent reference (20,60) and test surfaces (25,61), either parallel disks (60,61)  or coaxial cylinders (20,25) each having a relevant portion covered with a plurality of equally spaced lines oriented predominantly normal to the given direction and at an angle to each other, produce moire fringes (30) when illuminated (14,15).  One of the surfaces (25,61), being flexible, is connected to the shaft (8) so as to flex in response to torque between the reference point (24,59) and the test point (29,68), causing a change in the angle between the lines on the two surfaces (20,25;60,61), and thus of the spacing (D) (Figure 3) of the moire fringe bands (30), which is optically detected (17) and converted, as shown in Figure 4, to an electrical signal (42) to control power applied to the shaft (8).

Abstract: INFANT CARRIER - DISPOSABLE     Abstract of the Disclosure An infant  carrier which has  a  bed  inclined  in a shell; during a collision the bed moves in response to the inertial load of an infant to a more upright position to more uniformly load the infant and protect its head from undue load as well as to keep the infant in the carrier.  The carrier assembles from two planar precut preforms of cardboard.  The first preform folds  into a three dimensional shell with a hood at its upper end, a cowl at its lower end and an opening in the middle.  The second preform forms the bed defined by a back and a foot at an oblique angle to each other.  The top of the back holds a compound flap of the hood and two side flaps from side panels of the shell in place.  The foot extends into the cowl and bears on a bottom of the shell.   Support wings of the bed between the shell and the bed progres-sively crush during an accident to absorb energy; the bed back also crushes so that an infant moves with its back crushing the bed back preferentially at its base from an inclined position  to  a more  vertical  position  in  the carrier, avoiding  undue  load  on  the  head  and  sliding out of  the  carrier.   Wings  from the  side panels  fold inside the panels to form rigid,  double-thickness side walls and to present smooth exposed edges.  Bottom flaps from the side panels, from a back wall of the shell, and from a front panel  of  the  cowl overlap and are  held together by  tabs  extending  through  registered  slots.          Overlapping front panels at the anterior ends of the side panels form a front wall of the cowl.  Ears of one front panel extend into slots of the other.  A lap belt catch on an inclined surface of the cowl accepts the lap belt of a vehicle to hold the carrier firmly in place with the carrier  facing  rearwardly with  respect  to vehicle orientation.

Abstract: ABSTRACT       "Improvements relating to Collapsible Bicycles"     A collapsible bicycle comprises a triangular frame formed from three struts.  The bottom strut can be disconnected from the forward strut by operating a releasable pivot joint so that the strut can be folded up against the rear strut.  A universal joint between struts then allows these two struts to be folded to lie alongside one another with a pair of wheels lying side by side.        Cranked portions and of the struts provide offset supports for the wheels to one side only so that they can readily be positioned side by side and ideally locked together.  The folded framework can then be transported, if required, by grasping a support or handlebars and running the unit along the ground on the pair of wheels.   A saddle is adjustably mounted on the rear strut by a sliding support having fixing clamps.  The bicycle is preferably driven from pedals by means of a drive belt rather than a chain and the front pulley can incorporate a freewheel unit and/or gearing.

Abstract: ABSTRACT OF THE DISCLOSURE     The following specification discloses an apparatus and method for providing lifting motion on a substantially symmetrical and compact basis for a pump through a linkage, comprising two members pivotally coupled for relative movement driven by a gear reducer. The first member is driven in a rotational manner with the second member connected thereto being rotationally driven at the same angular velocity, but in the reverse direction thereto. The angular velocity of the members can be controlled by gears which can be eliptical, matched to an eliptically geared gear box for optimal acceleration outputs, or a timing chain and sprockets, or other timed drive means. As the first member rotates with the second member moving around the pivotal connection point at the same angular velocity, a lift point or pump connection is moved in a reciprocating manner to provide lift, such as to a polished rod assembly of an oil well rod pump. The members can be appropriately counterbalanced at an offset from the upper and lower lift points to provide rotationally angular counterbalance from the top and bottom lift points. The members can also be provided on either side of the gear reducer to provide dual lift points with one gear reducer and motor means. If a chain is used for timing the members, the chain can be enclosed in a housing with an oil bath which lubricates the chain and sprocket and associated bearings. Also, in lieu of counterweights an air balance piston can be used to balance a rod pump. When a gear reducer is used, the bull gear can be rotated by a gear in a lifting mode to relieve bearing load, while the orientation of the helical gears, if used, can be such to relieve side thrust.

Abstract: Abstract In a device for catching game fish, it is known to use a fish attractor or flasher in the form of an elongated plate-like body comprised of a reflective material.  In this invention, bends radiate in mutually opposite directions from a diamond-shaped central planar area.  The flasher can be produced in a variety of sizes and widths which affects the type of fish which are attracted to the flasher.           This invention relates to a fish attractor to be used in conjunction with a lead line attached to a lure for the purpose of catching game fish.           It is common in device for attracting fish to use an elongated plate-like body with bends in the anterior and posterior ends in mutually opposite directions which cause the device to simulate the action of a feeder fish.  The actual shape of such attractors is instrumental in determining how the device moves through the water.  The ability of this type of device to reflect light is dependent on the material of which it is composed and the way in which it spins in the water.           Previous fish attractors or flashers are of a double bent plate type with a planar central portion.  It is an object
