Abstract: Abstract of the Disclosure The invention provides a control apparatus for the charging spout of a furnace that is to execute movements about two different axes so as to achieve a conical movement with circular precession and variable angle of inclination.  The drive to the spout is by two hydraulic jacks controlled by the control device.  The drive shaft to the spout interacts with two feelers which produce independent correction signals that are fed to the jacks if the required movement is not being produced.          A safety feature is that the drive to the spout is via a universal joint and the mounting thereof includes elastic securing devices able to accomodate relative movements and shocks applied thereto.  The invention thus provides a "miniaturised" control apparatus and a driving mechanism that is not subjected to the stresses and strains of the spout and its suspension.

Abstract: ABSTRACT OF THE DISCLOSURE    The hitch assembly of the present invention comprises a hitch frame which is adapted to be mounted to the three point lift of a conventional tractor.  The hitch assembly includes a draw bar mounted to the hitch frame, and a hydraulically operated pin mounted above the draw bar. The pin is hydraulically movable downward into the pin receiving hole in the draw bar, and is also hydraulically movable upwardly into spaced relation above the draw bar.  A coil spring interconnects the hydraulic cylinder and the pin, and this coil is sufficiently flexible to permit the pin to deflect laterally in response to encountering immovable objects during its reciprocating movement.  A cable inter-connects the pin and the hydraulic cylinder through the center of the coil so as to prevent the coil from becoming stretched beyond a predetermined point. An overrun mechanism is provided on the hitch frame, and engages the fixed draw bar of the tractor so as to limit upward movement of the hitch frame with respect to the tractor. A modified form of the invention is adapted to be fixed to the draw bar of the tractor, and includes a grasping assembly for grasping the tongue of the vehicle to be towed, and lifting the tongue so that the clevis at the end of the tongue can be positioned in registered alignment with the draw bar of the tractor.

Abstract: TITLE               UV RADIATION TRIGGERED RAIL-GAP SWITCH                                 INVENTIORS Roderick S. Taylor Kurt E. Leopold A. John Alcock ABSTRACT OF THE DISCLOSURE The UV radiation triggered rail-gap switch applies a high volt-age from a low impedance source to a low impedance load.  The switch includes first and second parallel elongated electrodes spaced to form a uniform gap along their length.  The first electrode is adapted to be connected to the high voltage source, while the second electrode is adapted to be connected to the low impedance load. When a voltage from the source is applied to the electrodes, one electrode will be positive relative to the other electrode.  In addition, the cross-section of each of the electrodes is sufficiently smooth to prevent points of high field concentration between the electrode.  This cross-section is defined by the field enhancement factor of each electrode which is preferably less than 1.5.  The switch also includes an enclosure in which the electrodes are located and which contains a gas mixture for maintaining the break-down threshold between the electrodes.  A preferred gas mixture includes Ar, N2, and SF6 at a gas pressure selected to prevent breakdown in the switch until triggered by a UV radiation source. The W radiation source directs a beam of radiation substantially parallel to the pair of electrodes, preferably near the positive electrode, for initiating multi-channel, sub-nanosecond  jitter, breakdown in the gap between the elec-trodes.  The UV radiation may be obtained from either an incoherent radiation source or an UV laser source, but should be of short duration in the form of a narrow beam which is uniform along its cross-section.

Abstract: ABSTRACT      Conventional polyurethane foam products are modified by incorporating into the urethane reaction mixture a junction modifying particulate material that is selected with a critically controlled particle size relative to certain dimensional parameters of the foamed polymer matrix. This particulate material is selected with a particle size that results in location of the material in the foam cell wall junction regions rather than in the cell walls. The resulting products provided excellent physical properties (such as modulus of compression, tensile strength, elongation and tear resistance) at lower costs than normally encountered with similar unmodified foams. The preferred junction modifying particulate materials are organic polymeric materials such as ground rubber or plastics. As a result, the large particle size materials needed to achieve the junction modifying properties can be used without causing harmful abrasion or wear of processing equipment surfaces.

Abstract: "LOG SPLITTER ATTACHMENT FOR STABILIZING MACHINE ARMS OF  GROUND WORKING IMPLEMENTS"          ABSTRACT OF THE DISCLOSURE           Hydraulic log splitters are relatively expensive and are only used occasionally.  Owners of ground working implements such as back hoes and the like which include ram operated stabilizing arms, have a ready source of hy-draulic power available and this invention comprises a log splitter attachment for such stabilizer arms in which the hydraulic ram can be used to power the log splitter.  In one embodiment the ram piston is disconnected from the machine arm and the log splitter is mounted upon the machine arm whereupon the ram piston is connected to the sliding wedge component of the log splitter.  In another embodiment the log splitter is left in place and a transport rod is engaged between the fixed post and the sliding wedge of the log splitter so that extension and retraction of the ram raises and lowers the machine arm via the log splitter.  The trans-port rod is removed when it is desired to utilize the log splitter per se.  In both embodiments, the distal end of the log splitter is supported by a support arm  extending from the distal end of the base to the machine arm.
