A device for use by a bareback horse rider to enable use of stirrups for the rider's feet. A pair of cushion members are joined by a rigid gripping member in positions to lie on the back of a horse, forward of the rider. A first pair of rings are provided for attachment of a cinch strap, and a second pair of rings are provided for attachment of stirrups. Each cushion member includes a first flexible pad, fixedly positioned in the cushion member, and a second flexible pad movable in the cushion m...

An apparatus located within a conduit carrying a primary fluid is used to disperse a secondary fluid into the primary fluid. The apparatus includes an inverted cup to which are attached inverted troughs with serrated edges. Secondary fluid flows into the cup and outwardly through the troughs. The serrated edges form the secondary fluid into individual streams for dispersion into the primary fluid.

A printed circuit board assembly fixture capable of securing the circuit board in a fixed relation to the inserting element of an electrical component inserting machine relies on the staking anvil of the assembly to precisely locate the circuit board and electromagnets to lock the circuit board in position for insertion of electrical components.

A starter assist apparatus is taught for use in combination with a recoil-type starter operably connected to an internal combustion engine. Recoil-type starters include a recoil pulley biased in recoil direction, and a cable wrapped about the recoil pulley with the outermost end of the cable extending outwardly for brisk withdrawal to impart a starting impulse for the internal combustion engine. The arrangement of the new starter assist apparatus is such that, first of all, the cable from the re...

A device for measuring the intensity of minute magnetic fields comprising an optical magnetometer having a source for the emission of radiation, a radiation absorption cell means having the emitted radiation directed therethrough, and detector means for producing an output proportional to the intensity of impinging radiation from the source, wherein the detector means comprises a paraboloidal mirror and a detector element sensitive to the radiation and arranged within the mirror in a plane paral...

A waste spool for use with a ring twister comprising a frustoconical body member having a pair of tabs extending outwardly from its top surface. The particular structural relationship of the tabs with the tapered surface of the body member, coupled with a specified taper of the body member, provide a starting location for the waste windings that will enable their easy removal as a circular yarn wrap over the end of the waste spool.

Apparatus for automatically cutting pipe or tubing according to a desired pattern by securing the pattern to the tubing and by rotatably mounting around the tubing a constant linear speed, positive contact drive which traces the pattern and which is connected by a transfer arm to a cutting tool.

A close control of throughput in a reciprocating screw injection molding machine for elastomeric materials is obtained by a positive acting feed means located above the machine inlet and a choke-device mounted in the inlet to prevent balling of the material.

A sensory stimulator comprising an enclosed housing, a seat within the housing, and a plurality of sensory stimuli for stimulating the senses of a person seated within the housing.

Apparatus for supporting a floating boom which forms a barrier on the surface of a liquid and for forming a seal between the end of the boom and a fixed structure, for example a dock. The apparatus allows lateral and vertical displacement of the boom with changes of wind, current, or tide while maintaining the seal. A deformable, resilient wall held in pressure contact with the dock while supported on a vertically and laterally movable frame displaceable along a vertical pipe spaced from the doc...
