Abstract: An oyster shell separator deploys a conical, helically ridged, powered point driven in rotation by an electrical motor within a wedge shaped housing. The conical point draws the shells onto a flanged collar selected in dimension to fully separate the shells. From the collar the shell halves are passed along the sides of the housing for collection and sorting.

Abstract: A resilient grommet assembly useful in isolating the transfer of acoustical energy across structural connections includes a first annular portion provided with a central tubular projection in concentric deployment within a first peripheral edge and a second, mating annular portion provided with a second peripheral edge, the first edge extending to a depth greater than the second edge. The tubular projection is then inserted into a circular hole in a hanger strap and thereafter into a central opening in the second portion. A fastener then compresses the portions against the hanger and since the depth of the first edge is greater than the second edge the first edge is collapsed to a greater extent to further drive the tubular projection into the second portion.

Abstract: An aftermarket signaling system for use in an automobile including one, or more, manually powered ultrasonic sending units and an ultrasonic receiver which may be adhesively mounted in the automobile. The receiver includes a solar panel for recharging its own power supply and a set of lighted displays which are enabled by the ultrasonic signals from the sending units. The receiver may be mounted at the rear window of the vehicle and will thus provide visual signals to the following traffic.

Abstract: A thrust bearing assembly including a tubular mount conformed to receive an axially loaded shaft, the shaft being formed as a cylindrical shank terminating in a circular cap receivable in the interior of the mount. A selected number of rings is then stacked onto the shank to transfer lateral loads to the mount with a complementary number of discs being inserted below the cap for taking out axial loads. Each of the discs, furthermore, include oppositely arced grooves on the faces thereof for dynamic pumping of lubricating oil conveyed through the shaft.

Abstract: An ingot formed as an elongate structure characterized by a rectangular center body and reduced section handle structures on the ends of the body each provided with recesses for receipt of manipulative tools. The rectangular center body moreover, includes performations proximate each handle structure which are useful in storage and for the control of heat transfer for partial melting.

Abstract: A casting bench useful in casting limited quantities of articles includes a top base plate grooved longitudinally to receive opposed sliding cages each advanced by a corresponding first rack assembly. Each sliding cage, moreover, carries with it a corresponding second rack assembly useful in advancing lateral core plugs. Thus, exterior casting forms may be fixed to the sliding cages which then advance the cores for casting. The base plate may be releasably fixed to support legs and the whole structure may be disassembled for storage.

Abstract: A hair setting assembly including a hollow base provided with an electrical motor attached to drive a fan in a perforated enclosure affixed to the base. The air flow from the fan is then conveyed through a vertical, tubular extension, across heating filaments, to a flexible joint and thereafter to a distribution assembly includes a cylindrical cap telescopically affixed on a shaped end of a tube to selectively expose one or more openings to the airflow. Flexible hoses may then be inserted into the exposed openings to convey the heated air flow into hair rollers.

Abstract: An electromagnetic pickup for use in sensing the mechanical motion of strings includes a ferromagnetic housing of elongate, longitudinally recessed form in which a ferromagnetic core is received. The core includes a plurality of coplanar, spaced, finger-like projections directed at the walls of the recess. Both the walls of the recess and the finger-like projections of the core are permanently magnetized to a common magnetic polarity and thus will concentrate by magnetic repulsion the flux into the gap between the projections. A coil wound around the core then senses the flux changes of these concentrated flux fields due to string motion.

Abstract: An inflatable flotation assembly includes a compressed gas cylinder stored inside a split housing the parts of which are held together by a releasable pivot on one end and an interlocked pivoted arm at the other end which engages a flexible tab aligned against the gas cylinder. The arm overlies the housing to engage the releasable pivot and when unclasped from this engagement will rotate to pierce the cylinder by deflecting the tab. Thereafter the expansion of a flotation bladder separates the housing while the arm remains interlocked to the tab to control the rate of gas release into the bladder by the angular inertia of the arm around its pivot.

Abstract: A motorcycle carrier is conformed to extend on an incline from the back of a vehicle in its first position and to articulate to a vertical alignment at the back of the vehicle in its second position.
