Abstract: ABSTRACT OF THE DISCLOSURE:     A rail vehicle is disclosed which includes a bottom discharge hopper supported on an elongated, rectangular base frame.  A bogie frame is provided beneath the base frame at each end thereof, the bogie frames carrying the vehicle wheels.  Each bogie frame comprises two laterally spaced longitudinal members and a transverse member.      Bearings are provided between the bogie frame members and the longitudinal and transverse members of the rectangular base frame.  These bearings comprise rolling elements in arcuate grooves, the grooves being generated about the vertical pivotal axis of the adjacent bogie frame.  Pins are provided which extend downwardly from the base frame and through arcuate slots in the bogie frames.  The pins have structures at their lower ends for preventing upward withdrawal thereof through said slots.  The slots are generated about the pivotal axis of the adjacent bogie frame.

Abstract: Abstract of the Disclosure The present invention provides a process for preparing branched chain, thermoplastic polymers having improved melt strength and die swell properties.  This process comprises reacting at least one thermoplastic polymer capable of reaction with an epoxy or isocyanate functionality, the polymer being in the molten state, with at least one branching agent selected from the group consisting of epoxy containing at least two epoxy groups per molecule of epoxy branching agent, and iso-cyanate containing greater than two isocyanate groups per molecule of isocyanate branching agent, to produce branched chain thermoplastic polymers having a melt strength ratio of T2/T2 of less than about 2.0 at 235°C.           The molten, thermoplastic, branched chain polymer reaction product has increased melt strength and intrinsic viscosity. The increased molt strength polymers also have improved die swell characteristics and are useful in extrusion applications such as blow molding.

Abstract: Abstract Composite sections, comprising at least two metal sections and between these a hardenable plastic foam, are produced in a device in which two facing conveyors provided with a means of temporarily gripping the metal section lead the sections at a set distance apart through the device. Sealing belts, which travel round with the conveyors, bridge the gap between the metal sections during the foaming and hardening stages.  These sealing belts ensure that the exposed plastic surface has pore- free skin.  The gripping facility on the conveyors is exchangeable and therefore the kind of composite section which can be produced on such production equipment is not limited by the way the conveyor engages the sections.

Abstract: ABSTRACT           The sweep auger apparatus is radially mounted within a circular bin for storing granular free flowing material and is horizontally rotatable across the bin floor about a vertical axis located centrally of the bin to re-move from the bin floor, during each horizontal rotation thereof, a uniform depth of material. The sweep auger is of a constant diameter and uniform pitch and is positioned within a housing structure of a generally right angle shape in transverse cross section that has an upright leg located adjacent the rear side of the auger and a generally hori-zontal leg arranged adjacent the top side of the auger and protected forwardly from the front side of the auger. The depth of material to be removed is dependent on the angle of repose or flow of the material relative to a horizontal plane. The front edge of the horizontal leg is vertically disposed and spaced forwardly of the auger front side such that the auger, during each horizontal rotation across the bin floor, is capable o removing all material flowing thereto from below the horizontal leg.

Abstract: Abstract of the Disclosure: Electric power is equivalent to the product of voltage and current in a power circuit.  The present invention employs, as a multiplier to obtain the product of a voltage and a current, a pulse-width modulator which consists of an integrator, a comparator having a hysteresis characteristic connected to the output side of the integrator, and a feedback circuit for feeding the output of the comparator back to the input side of the integrator.  The volt-age of the power circuit is applied to the pulse-width modulator of such a circuit configuration so as to be pulse-width modulated, and the output of the modulator serves to intermittently turn on or off an analog switch to which the current of the power circuit is applied, thereby multiplying the voltage by the current.  The integrator, comparator and feedback circuit constituting the pulse-width modulator and also the analog switch are composed entirely of electronic circuits, and the inputs of both the pulse-width modulator and the analog switch are equipped with a protective circuit against an impulse input. For conversion of a single-phase power to a d-c signal, one pulse-width modu-lator and one analog switch are employed as described above; and for measure-ment of three-phase power, three-phase reactive power or three-phase four-wire power, two pulse-width modulators and two analog switches of the same composi-tion are employed.

Abstract: ABSTRACT OF THE DISCLOSURE         Disclosed herein is a throttle control for an engine including a housing supporting a control lever for rotation relative to a neutral position, a throttle lever movably mounted on the housing and adapted to actuate the engine throttle, a throttle drive member including a drive pin and mounted for rotation in response to movement of the control lever from the neutral position, and a cam member connected between the throttle lever and the throttle drive member.  The cam member includes a cam track receiving the drive pin and having a shape effective to displace the cam member relative to the throttle drive member, transversely relative to the rotational axis of the throttle drive member, so as to move the throttle lever in response to rotation of the throttle drive member.         In one embodiment, the control further includes a shift lever movably mounted on the housing and adapted to actuate the engine clutch and a shift drive member drivingly connected to the shift lever for actuating the engine clutch in response to movement of the control lever from the neutral position.  The cam track is arranged so that the cam member, and thus the throttle lever, remains in an engine idle position during initial movement of the control lever from the neutral position to actuate the engine clutch and so that further movement of the control lever from the neutral position causes translatory movement of the cam member to advance the engine throttle.
