Abstract: ABSTRACT OF THE DISCLOSURE        Disclosed is a fifth wheel coupling for mounting on a towing vehicle for coupling to a trailer king pin.  The coupling includes a coupling plate and a pair of jaws operatively connected to the plate and having opposing king pin receiving recesses with their centres forwardly of the axis of rotation of the jaws and having faces forming a rear-wardly directed recess when the jaws are closed.  A locking plunger is movable with respect to the plate and is urged into the rearwardly directed recess.  A trip lever is mounted on the plate and is urged to maintain the plunger in an inoperative position out of the rearwardly directed recess and it is trippable by closing movement of at least one of the jaws.  A locking block is movable with respect to the plate and plunger from an inoperative position to an operative position in which it prevents movement of the plunger out of the rearwardly directed recess.  An actuating member is mounted on the plate and movable, by movement of the block to its inoperative position, to move the plunger out of the rearwardly directed recess to free the jaws.

Abstract: POOL TABLE QUICK RACK SYSTEM              ABSTRACT OF THE DISCLOSURE        A pool table quick rack system in which a triangular rack is seated in a triangular carrier in a triangular opening at one end of the pool table.  The ball return channels of the pool table terminate so as to deliver the balls into the top of the rack in the triangular carrier.  When all of the balls have returned to the rack the carrier with rack and balls is removed from the triangular opening in the table and placed on top of the table.  The carrier is then slid forwardly while the rack is held in its position against the cushion until the rack is completely disengaged from the carrier.  The racked balls are then moved to the correct position on the table and the rack is removed and replaced in the triangular carrier and the carrier and rack are placed in the triangular opening in the pool table.  A handle on the carrier is positioned high enough above the balls in the rack so as to permit the rack to be disengaged from the carrier when the balls in the rack are stacked and some of the balls have not moved to the correct position in the rack.

Abstract: ABSTRACT OF THE DISCLOSURE   This invention relates to a processable ionic elastomer compositions having improved compression set properties, especially at elevated temperatures. In this invention an intractable ionic elastomer, for example, a sulfonated elastomer is blended with from 10 to 70 parts per hundred of a crystalline polyolefin to yield novel compositions having the above properties. Preferably the ionic elastomer is a sulfonated ethylene propylene terpolymer having from about .2 to 20 mole percent sulfonate groups, at least 95% of which are combined with counterions selected from the group consisting of Groups IA, IIA, IB and IIB of the Periodic Table of the Elements, aluminum, antimony, lead, and mixtures thereof. The sulfonated polymer is combined with said counterions by neutrali-zation of a polysulfonic acid precurser with a basic material in which the desired counterion is present as the cation thereof. The anion of said basic material is preferably selected from the group consisting of oxide, hydroxide, and lower alkanoates, for example, acetate, formate, and propionate.

Abstract: PIPE CAGE END FORMING MACHINE AND METHOD                 ABSTRACT OF THE DISCLOSURE          The specification discloses apparatus and a process for forming the female or bell end of welded wire reinforcing cages, particularly cages of the type used to reinforce concrete pipe.  A cylindrical wire cage assembly is automatically centered and positioned within the apparatus and the bell end is formed by elongating one or more of the circumferential wires at one end of the cage.  A force is applied between two points on the circumferential wires to simultaneously expand the wires and rotate the cage.  A heat source is applied to a localized zone between the two points on the wire.  The heat source and wire are moved relative to each other such that the heat zone moves along the wire as the force is applied.  The wire is stretched under the force being applied to thereby continuously reduce the diameter of the wire and elongate the wire as it is moved relative to the heat source.

Abstract: ABSTRACT OF THE DISCLOSURE      Orthopedic structures are prepared from a thermal softening resin (e.g. polycaprolactons) impregnated large mesh knit fabric carrier having relatively large diameter strands and having a relatively high weight ratio of the polycaprolactone or equivalent resin composition to the fabric carrier.  The impregnated fabric can be formed in rolls which may be warmed above the softening temperature of the resin.  The thermally softened impregnated fabric becomes highly flexible and pliant and may then be wrapped in multiple layers about the limb to be immobilized.  The large knit fabric carrier allows for twisting of the fabric, forming and reforming, so as to obtain the desired shape and degree of support.  The overlapping layers of impregnated fabric bond to each other during wrapping and whereafter the impregnated fabric rapidly cools to a hard structurally stable cast, which is porous so as to minimize maceration or other deletrious skin conditions from developing.

Abstract: Abstract of the Disclosure The present invention comprises speed control systems ant methods for universal-type electric motors.  A typical motor speed control system according to the present invention includes a power modulator circuit, for example a controlled bridge rectifier circuit, for controlling the power supplied to the motor.  A current transformer or a resistor provides a voltage which is directly proportional to the instantaneous motor terminal current.  A potentiometer connected to the current transformer and a resistor connected to the potentiometer tap provides a sensing current which is directly proportional to the voltage across the current transformer, ant thus to the instantaneous motor terminal current.  A potentiometer connected to the motor and a resistor connected to the potentiometer tap provides a sensing current which is directly proportional to the instant-aneous motor terminal voltage.  A summing amplifier algebraically sums the instantaneous values of the two sensing currents and an integrating amplifier averages the sum of the instantaneous values.  A feedback circuit generates a signal for operating the controlled bridge rectifier, the signal having a phase determined by the output of the integrating amplifier, whereby the output of the integrating amplifier controls the phase of the controlled bridge rectifier and thereby controls the power supplied to the motor.

Abstract: ABSTRACT Teat cups are pulsed by a valve in a duct leading from the shell into the pulsation space between a resilient inflation and the shell.  The valve alternately opens the pulsation space to ambient pressure and to a source of vacuum. The source of vacuum in the receiver or milk lines is in communication with the pulsation space through a tube or passage that is controlled by the valve.  A timer connected to a solenoid actuator for the valve unseats the valve to allow air to enter the pulsation space, whereupon the inflation assumes a normal configuration.  Upon seating to close ambient air entry while establishing vacuum to the space, the vacuum flattens the inflation.  The timer sequences the air movement to ensure that milk flowing to the receiver clears the milk from the inflation and prevents back flow to the animal's teats.
