Abstract: ABSTRACT OF THE DISCLOSURE           A stacker attachment for use to extend the versatility of a battery powered two wheel hand truck which can lift loads from one level to another and, more importantly, operate as a walker for moving loads up and down the stairs; but which two wheel hand truck cannot operate as a stacker because its inner movable frame can never be raised above the wheels at the bottom of the stationary frame of the two wheel hand truck.          The stacker has a long stationary frame but a short inner movable frame relative to the stationary frame.  The stacker has an elongated screw shaft which freely rotates in a journal at the top of the long stationary frame, but which is operatively joined to a bearing nut fixed to the top wall of the inner movable frame, and is operatively engaged to the electric motor.  The short inner frame has a long lifting path along the elongated stationary frame for lifting and stacking loads.          The stacker is releasably but securely mounted to the two wheel hand truck, and the stacker has conductors and elongated battery leads which can be connected to the battery carried by the two wheel hand truck.  Switch means on the stacker selec-tively rotate the stacker lead screw in one of two opposite rotational directions to lift the inner movable frame, and an attached lifting plate raises loads for stacking, and also lowers such inner movable frame to its starting position at the bottom of the stacker.

Title: Throttle structure for imparting supersonic flow characteristics in the intake manifold of an internal combustion engine
Inventor: HICKS DONALD L
IPC: F02D9/12
Filed: 1977-09-08
Granted: 1980-01-15
Abstract: Abstract of the Disclosure A combustible mixture of air and minute fuel drop-lets is produced for supply to the cylinders of an internal combustion engine.  The engine includes a carburetor having a main air passageway in it, and an intake manifold inter-posed between the engine and the carburetor.  The intake manifold includes at least one wall defining a plurality of fluid passageways operatively connected to the carburetor and to the combustion chambers of the engine.  A throttle structure is mounted in the intake manifold. The combustible mixture is formed by introducing liquid fuel into a stream of intake air and uniformly distributing the fuel in the air by passing the air and fuel mixture through a constriction to increase the velocity of the mixture to sonic speed.  The constriction occurs at the throttle structure in the mani-fold.  The area of the constriction and the amount of fuel entering the air stream are adjustable for correlation with engine demand.  After passing through the constriction, the air/fuel mixture is accelerated to supersonic velocity and thereafter decelerated to subsonic velocity to produce a shock zone where the fuel droplets are believed to be further subdivided.  The supersonic and subsonic mixture speeds are obtained at the outlet of the throttle structure in the mani-fold.  Thereafter, the mixture is inducted into the combustion chambers of the engine.  Preferably, the throttle structure includes a cylinder movably mounted in the intake manifold.          A plate either is suspended in or forms a part of the intake manifold.  The plate and cylinder coact to provide the con-striction, supersonic and subsonic zones of the mixture flow.          Means are provided on the cylinder for delimiting those zones of mixture flow.

Abstract: ABSTRACT OF THE DISCLOSURE         A tone signal detecting circuit for sequentially receiving and passing several tone signals is disclosed. A control circuit is respon-sive to a first control signal for selecting one of several clock signals the frequency of which is, respectively, equal to N (where N is an integer at least as great as 2) times the frequency of the several tone signals. An N-path filter is provided having prescribed parameters for selecting the tone signals in accordance with the clock signal selected by the control circuit. Another filter is provided to remove harmonics from the tone signals received from the N-path filter. The frequency characteristics of this filter are changed in response to a second control signal. A detector connected to this other filter is responsive to each of the tone signals sequentially passing through the N-path filter for providing a detected output. The first and second control signals are generated in response to the detected output.

Abstract: ABSTRACT     A method is described for producing a continuous strip of simu-lated bacon by low temperature extrusion of three differently colored doughs to form a common strip containing three or more distinctly different colored zones which are continuously and randomly varied in width. Differences in extrusion rates among the doughs may be used to impart crinkling and curl-ing of the strip which is heat treated after extrusion, thereby setting the structure and preserving the crinkling and curling. The strip contains an emulsion which is designed to be stable during processing, and during storage, but which is unstable during cooking. During frying or baking the emulsion becomes unstable, thereby rendering out oil upon the cooking sur-face, making it unnecessary to add oil, grease, or frying aids during cook-ing, and thereby closely simulating the cooking attributes of real bacon.

Abstract: ABSTRACT OF THE DISCLOSURE         A hook fastener of plastic material for garments, particularly brassieres, consists of two platelike fastener members, the first member having an arched bridge which protrudes from a major surface of the member and also having a complementary aperture in the major surface, which aperture has a contour which includes the projection of the bridge onto the major surface.  The first member includes a portion for fixing the member to a garment.  The second member has a portion for fixing the member to a garment.  It also has at least one aperture and at least one lug, which lug may be received in an opening defined by the bridge of the first member.  The aperture in the second member has a rectangular configuation with two edges extending in the direction in which tension is applied to the fastener and two transverse edges.  One of the transverse edges is remote from the fixing portion of the second member and the other of the transverse edges is close to that fixing portion.  The lug extends from the first transverse edge into the aperture in the second member and has an end which is spaced from the other transverse edge by a distance which is large enough to allow the insertion of the bridge into the aperture of the second member.  The fastener of the present invention clearly overcomes the problem of metallic fasteners and the fasteners of the invention also do not apply local pressure to the body of the wearer.
