Abstract: ABSTRACT           The present invention relates to wire stranding machines.  In the prior art, such machines have been incapable of evenly laying the wires onto a reel and of avoiding unevenness at the inside of the flanges.  the present invention overcomes these deficiencies by pro-viding machine having a reciprocating flyer traversing the length of a take-up reel and rotating coaxially with respect thereto, such take-up reel being mounted within pivoting means to facilitate easy removal of the reel after it is fully wounded with wire.  The invented machine comprises electro-mechanical means for automatically controlling the uniformity of the lay length of the twisted wire by correcting for changes in the velocity of the wire being fed into the machine due to wire build-up on the reel or to reversals of the traversing flyer.  Additional control means are also disclosed for automatically controlling the points at which the flyer, in its reciprocating motion, reverse direction, thereby minimizing wire accumulations or recesses at the end flanges of the reel.

Abstract: ABSTRACT OF THE DISCLOSURE A casting furnace includes upper and lower chambers, separated by a wall having a pouring path extending therethrough.  A crucible is positioned in the upper chamber and a mold is positioned in the lower chamber, both in alignment with the pouring path. A body of casting metal is placed in the crucible and is melted from the top down by an electric arc generated in the upper chamber, the bottom portion of the body of casting metal blocking the pouring path until the cast-ing metal has become molten.  Thereafter, the molten casting metal falls by gravity through the pouring path, and into the mold.  The arrangement is such that the molten metal requires nothing but the force of gravity to enter the mold cavity.

Abstract: ABSTRACT A fur-like napped fabric and process for manufacturing same are dis-closed wherein a fiber layer comprising uncrimped short fibers or short fibers having a number of crimps of not greater than 10 crimps per inch are provided as a fiber layer on a base fabric.  The fibers are then implanted into the base fabric by needle punching.  Thereafter, the fibers are raised to form a nap. After needle punching, the base fabric and fibers may be bonded to each other by means of a backing treatment or the like which is carefully applied so as not to permeate the raised hair portion existing on the front surface of the fabric.  Especially pleasing aesthetic effects are produced when the napped fibers have static frictional coefficients of less than 0.35 and wherein the bending recovery rate of said fibers is higher than 50%.

Abstract: TITLE:  TOY HAVING ATTACK OBJECT LOCATED ON ARCUATE MOVING FRAMEWORK             ABSTRACT     A toy game includes a housing having a plurality of target members positioned in a side by side manner near one end of the housing.  An attack object can move from a central position in the housing toward the target members and if correctly positioned it can interact with the target members.  The attack member is capable of two modes of movement, however, it can only move in one mode at a time.  One of the modes of movement is a transverse movement essentially across the width of the target members.  The other mode of movement is from a starting point near the central portion of the housing toward one of the objects.  If the two movements are coordinated the attack object is capable of interacting with one of the targets.  A drive motor moves the attack object in each of the modes of movement via a motion diverting mechanism which is capable of converting motion of the motor into one or the other of the modes of movement at any specific instance of time.

Abstract: ABSTRACT A milker has a lower base with a concave bottom and a lower exit under vacuum that can be closed by a float with valve until the milk level pivots and/or raises the float to open the exit.  An enclosure body is fitted on the base and includes a main vacuum inlet and a milk inlet nipple positioned and angled to direct milk inflow at the side and/or below the float.  An en-closure cap is releasably fitted on the top of the enclosure body and mounts an air valve, pulsation nipples and a further vacuum inlet.  A central stem from the bottom extends up through a central passageway in the float and also through the cap to afford a fulcrum or support for an arm that pivots or slides to close the main vacuum inlet when the air valve is opened. The float can pivot and rise to a limited extent when milking or when the milker is in-verted for washing.  The assembled cap, enclosure body and base are interfitted and sealed when the inlets and milk outlet are in alignment.  With the assembled milker, there is no milk backflow and the float acts as a baffle for milk in-flow.  When the milker is drained of milk, the float promptly valves the exit shut to preserve the vacuum.
