Abstract: A fuel system of the gaseous type utilizing the gas such as propane, methane or the like, wherein gas, preferably in liquefied form, in a tank carried in the trunk compartment of a car, for example, is taken from the tank in gaseous form and conveyed to the intake manifold of the internal combustion engine of the car at very low pressure, through a feeder gasket installed between the carburetor and the intake manifold. Thus it does not require modification of the existing carburetor or replacement thereof, and when installed for alternate use with an existing conventional type gasoline fuel system, means are employed for selectively switching from one system to the other.

Abstract: An infant's feeding bottle employing a valve to assure approximately atmospheric pressure within the bottle during feeding, the valve and valve stem being of like material and of simple unitary construction whereby to avoid numerous problems such as rust, sticking, and development of unsanitary conditions associated with other valves under like conditions of use.

Abstract: In association with a foldable chair having retractable back and seat cushions for storage purposes, means are provided for elevating the cushions for use, after the chairs have been unfolded and arranged in rows.

Abstract: An arrow rest assembly including a coil spring or equivalent having multi-directional flexibility including flexibility in various planes serves to more effectively dampen oscillations set up in an arrow when released from a bow.

Abstract: A press, comprising a frame supporting an upper and lower bed for attachment of an upper and lower bolster, the upper and lower bolster each carrying mating halves of a complementary die, and the upper bolster having a knock-out opening therethrough, a hydraulic knock-out means carried by a drive means above the upper bolster that is adjustably electro-mechanically timed to cooperate with pins internal to the upper bolster to eject any work that may have remained in the upper die upon separation of the two mating die halves.

Abstract: A device for the storage of pretied fishing leaders comprised of a reel having two sides separated by a plurality of radially situated spacers equally spaced from and about the center axis of such reel and a housing that rotatably locks with the reel such that it may be turned within the housing to serially wind a number of fishing leaders loosely about such spacers to prevent them from tangling.

Abstract: A back-gauging system for a shear machine that derives support from the side housings of the machine and is designed with a rotatable movement gauge stop and slideable control guides to enable the gauge stop to be moved above the work plane for shearing work pieces longer than the maximum gauge range, to eliminate excessive force being transmitted to the gauge drive when gauging or shearing and to eliminate wedging of sheared pieces between the knives and the back-gauge stop.

Abstract: A means for producing extremely high pressures especially adaptable for use in the art of diamond making, such means employing the expansion characteristics of materials and includes a member expandable in response to heat for applying pressure to diamond producing material.

Abstract: A skimmer assembly adapted for installation through an opening in a pool wall from the rear side thereof to mask the otherwise exposed edges of the wall opening, includes a circular type weir involving a float having means for offering resistance to dropping of the float in response to operation of the pool pump, whereby to minimize and stabilize the layer of water flowing over the weir.
