Abstract: A cable connector for securely connecting an electric cable to the housing of an electric device such as a motor. The connector includes a body and a nut, the body having a rearwardly extending, elongated neck with an internal bore through which may be passed a cable or the like. The neck is externally threaded along at least a portion of its length to receive the internally threaded nut, and the wall of the neck has at least one generally U-shaped slot therethrough to provide at least one forwardly-extending ear movable radially inwardly and outwardly of the neck. The radial thickness of the at least one ear increases forwardly, with the thickness of the ear at its forward end being greater than that of the adjacent neck walls, whereby, as the nut is threaded forwardly onto the neck, the ear is cammed inwardly of the bore to firmly grasp a cable.

Abstract: A molded stackable flower pot provided with an annular rim adjacent the bottom thereof, which supports the pot so that the bottom surface is spaced upwardly from a surface supporting the pot. The rim has a plurality of apertures defined therein positioned so that the apertures will received peripheral upper edge portions of two other similar flower pots so that pots can be supported in a stacked and interlocked relationship to each other.

Abstract: A variable capacitor having a ceramic stator with a flat major surface for engaging a flat conductive rotor plate mounted on a shaft extending through the stator. The other major surface of the stator has a transverse slot having a capacitance forming electrode over the bottom portion that is substantially parallel to the flat major surface. A spring biased rotor terminal is affixed to the end of the shaft extending through the stator.

Abstract: A wide range wheel chuck in which three wheel engaging chucks are disposed on the ends of three lever arms. The lever arms are rotatably journaled at the other end to a stationary base and at a point intermediate their ends to a base that is rotatable with respect to the stationary base. Relative movement between the bases results in simultaneous equal radial motion of the chuck jaws at the first ends of the lever arms.

Abstract: A hollow, open ended tube of flexible, semirigid material which has internally projecting ridges that are so shaped and positioned as to produce a musical tone when air flow is induced through the tube by holding it at one end and swinging the other end around in a generally circular path to create a pressure differential between the two ends of the tube or by mounting the tube on the exterior of a vehicle in line with the relative airstream when the vehicle is in motion. The tube may be attached at one end to a hollow, extensible, spring-loaded handle.

Abstract: An improved router bit that has numerous advantages over conventional router bits; the bit of the present invention allowing chips to fall through quite readily, making a smoother cut and having other advantages; the bit having two or more flutes, one of the flutes having a cutting edge with a radius of conventional bits, the other flute or flutes being radially shorter, thus giving such flute or flutes a less circular limit.

Abstract: A convection oven of the rack type for treating goods, e.g., baking bread, including a rotating duct which sequentially delivers heated air to a series of ducts which distribute the heated air across the oven chamber according to a flow pattern which provides uniform treatment of the goods while maintaining the goods and the rack stationary with respect to the oven chamber.

Abstract: A cap-type flue damper mountable in the flue opening, the cap position relative to the flue opening being controllable from controls located at the hearth, the damper having a built-in brake which prevents the cap from closing in the event of a malfunction in the spring urging the cap in the open position.

Abstract: A performance method and apparatus for evaluating the bouncing or rebounding characteristics of objects such as balls used in games, and for evaluating the energy-absorbing and surface characteristics of playing surfaces of games.

Abstract: A fuel system for providing fully vaporized, air-free gasoline to a carburetor of an internal combustion engine. The system includes an air-free liquid gasoline receptacle having means maintaining a liquid free space above the surface of liquid gasoline in the receptacle, a heater within the receptacle and having an expanded surface of which at least a substantial portion extends upwardly out of the liquid gasoline into the space there above, means for producing a vacuum within the receptacle to promote evaporation of liquid gasoline from the expanded surface and for compressing the resulting gasoline vapors, and air-free means for filtering condensed droplets of gasoline from the resulting gas vapors.

Abstract: A pulse width modulated motor control system in which the power supplies for forward and reverse operation for the motor are provided to supply electric energy at different levels. The control signals for the motor are provided in such a manner that the average energy of unbalanced pulse periods is the same, but the potential level differs by a substantial amount. Energy storage may be provided for in conjunction with the lesser of the two power supplies to assist in a rapid reversal, stop or shaft positioning of the motor.

Abstract: Wheel alignment apparatus for electrically indicating the alignment condition of a vehicle wheel in which there is sensing means, including an element adapted to be detachably secured to the wheel, for producing an electrical output dependent upon the extent of inclination of the wheel and an electrical display device having a movable member positioned in accordance with the electrical output of the sensing means. The sensing means is designed to selectively detect toe-in, camber, and caster.

Abstract: An ingredient whipper that utilizes the mixing action of a plurality of rotating axially spaced apart inclined blades of segmental arc, cycloidal like, configuration in a chamber that is adapted to receive materials to be mixed through one opening and to discharge the same through another opening. The segmental arc blades may coact with a further longitudinally extending rib of segmental arc cross section in the chamber to provide a complete mixing of the ingredient materials supplied to the chamber. The blades are disposed in such a manner as to direct the materials being mixed in a direction away from the outlet opening in the chamber.

Abstract: A shock resistant microphone embodying a piezoelectric transducing element that is held in operative disposition with respect to an electrode and a diaphragm by a resilient spring also forming a second electrode.

Abstract: A fluid operated device in which an externally toothed rotor is rotatably disposed in a chamber and an internally toothed member is orbitally but not rotatably disposed in the chamber about the rotor. The rotor and orbital member are operative upon relative rotation to form fluid containing pockets therebetween and suitable fluid ducts are provided for conveying fluid to and from the fluid containing pockets. The orbital member is provided with means to cooperatively engage the housing to limit, or prevent unidirectional rotational motion of the orbiting member but to allow orbital movement about the axis of rotation of the rotor.
