Abstract: SELECTIVE DRIVE FOR TRUCK DEAD AXLE            ABSTRACT OF THE DISCLOSURE: The selective drive unit performs the function of dual tandem rear differential drive on heavy duty trucks. The drive unit is employed between the tires on the wheels on the driven axle and those on the dead axle. The drive embodies a rotatable axle mounted on the chassis frame or suspended from the two axles with a pneumatic tire fixed on each end of the axle. The inflatable tires are disposed between a set of tires on the driven and dead axle, preferably on or near the centerline therebetween. The drive tires are pre-ferably expandable and simultaneously or selectively inflated to engage the tires on the driven and dead axle on one or both sides of the truck. The inner tires of the pair located on both sides of the chassis frame are engaged by the ex-pandable tires which may have an extending tread which engages the recesses of a matching tread on the truck tires. This provides a positive non-slip drive between the driven tires and those on the dead axle. The air in the inflatable tires is controlled by the driver from with-in the cab using the air provided on the truck for operating the brake thereof. The air causes the tires to be pressurized and preferably to be expanded so as to have a substantially flat area of engagement with the tires on the truck. The inflatable tires have the soft rubber surface thereof project within the recesses in the truck tires or, as pointed out above, may have a projecting tread which will mate with the openings in the tire tread to provide a locking engagement which reduces slippage and provides positive and frictionless torque transmission when both of the tires are pressurized. When both of the inflatable tires fixed to the rotatable shaft are pressurized the free wheeling effect of the driven differential is locked and torque from the truck motor is distributed to all eight tires simultaneously. When it is hazardous to lock up all of the eight wheels, only one of the inflatable tires need be pressurized to thereby provide a drive for all of the four tire on one side of the truck.

IPC: B30B9/28
Filed: 1977-08-03
Granted: 1980-02-05
Abstract: ABSTRACT OF THE DISCLOSURE        This invention relates to refuse compactors.  It is previously known to utilize compressed air for driving a compactor plate through a compression stroke.  These super-atmospheric air powered compactors have certain dis-advantages and inherent safety hazards due to the com-pressed air.  Also known are compactors in which the com-pression stroke is accomplished by evacuating the refuse space, thereby driving of the plate through the stroke by atmospheric pressure acting on the outer surface of the plate, and the pressure plate returned by spring action upon venting of the refuse space to atmosphere.  However, this return system has been found to be costly and un-reliable.  The present invention provides a refuse com-pactor having a container with a refuse compression space on one side of a pressured plate which is movable by atmos-pheric pressure, upon evacuation of the refuse space, in one direction through a compression stroke to compress refuse in the space.  The pressure plate is movable in the opposite direction through a return stroke by either pressurizing of the refuse space or evacuation of a space, which may be a second refuse compression space, at the opposite side of the plate.  The refuse compactor may be adapted to be emptied by a conventional trash collection vehicle equipped with a trash bin elevating and inverting mechanism.  The compactor includes a novel vacuum pump and valve system for operating the pressure plate.

Abstract: COUNTERCURRENT DINITRATION    OF BASALIN PRECURSOR      ABSTRACT     In accordance with the present invention, there is provided herein  a  cyclic,  two-stage  process  for  dinitrating  4-chlorobenzotrifluoride       to       form       4-chloro-3,5-dinitrobenzotrifluoride in high yield.  The process commences with a mononitration stage wherein 4-chlorobenzotrifluoride is substantially    completely    converted    to    4-chloro-3 nitrobenzotrifluoride   (the  "mononitro"  compound)   in  the presence of a nitric acid, sulfur trioxide and sulfuric acid mixture.  The used acid mixture then is diluted with water to form an aqueous used acid layer in which the solubility of the mononitro compound is negligible and a mononitro layer.  The aqueous used acid layer then is separated from the mononitro layer and discarded.   The mononitro compound thereafter is further nitrated in a dinitration stage in the presence of a fresh nitric acid, sulfur trioxide and sulfuric acid mixture. The  fresh acid mixture contains  an excess of nitric  acid sufficient to carry out both nitrations using the partially spent acid mixture of the dinitration stage as the acid mixture for  the mononitration stage.   The reaction product of the dinitration  stage  is  the  desired  dinitro  compound  and  a partially  spent acid mixture,  which  contains  some dinitro compound  dissolved  therein.    The  dinitro  layer  then  is separated from the partially spent acid layer and recovered and the acid layer is recycled back to the mononitration stage.

Abstract: ABSTRACT OF THE DISCLOSURE      An analog speed error signal, developed by comparing actual and desired speeds, is processed into a control voltage through a two condition circuit network. When the error signal is more than a predetermined percentage of the desired speed, the network has a unity gain and the control voltage equals the error signal. When the error signal becomes less than the predetermined percentage, the network is shifted into a hybrid form by inserting an integrator loop into the gain circuit so that the control voltage and error signal are not directly proportional. The control voltage is converted into a series of proportional width pulses which are applied to vary the generator output to control locomotive speed. The pulse width varies in part from the error signal variation but also in part from an acceleration signal to anticipate the achievement of desired speed. When the hybrid network is in use, the pulse width speed control feeds back to drive the error signal to zero. The control voltage and acceleration signal ar  also applied to a clock and reversible counter network which controls the locomotive throttle position. The counter steps up or down, to increase or decrease the throttle, at a clock frequency established by the absolute value of the control voltage whose polarity further designates the require-ment for speed increase or decrease. A high level of acceler ation, however, overrides to reverse the count direction to prevent overshooting the desired speed. A moderate accelera-tion level inhibits further counting and speed is  then varied only by the pulse width modulation network.

Abstract: ABSTRACT OF THE DISCLOSURE            A bulk storage facility for pulverulent friable or fungi-ble material, such as coal, is disclosed having a slot defined by downwardly convergent inclined walls each of which arc fabricated from a plurality of wall panels.  The wall panels arc the facing for a coherent mass that includes a multiplicity of thin flexible reinforcing strips that arc each surrounded by particulate mater-ial.  Each wall panel has an inclined surface which defines an angle with respect to a horizontal plane that exceeds the angle of repose of material to be stored in the bulk storage facility.          In addition, each wall panel may be provided with a pair of gussets which extend into the particulate material positioned therebehind.  Several flexible metal reinforcing strips may be attached in vertically spaced relation to each of the gussets.          Each edge surface of the wall panel has a tongue and an adjacent rabbet such that, when the panels are assembled in a wall, adja-cent panels interlock to restrain the panels against rotation about horizontal and vertical axes.  The method of construction includes building the inclined walls by laying a first course of panels, backfilling the panels with a layer of particulate material, attaching a generally horizontal planar array of rein-forcing strips to the panels, covering the planar array with a lift of particulate material;  repeating the attaching and cover-ing steps until the first course of panels is completely back-filled, placing a second course of panels on the first course with sealant material therebetween, repeating the procedure for backfilling and placing additional courses with backfilling until the wall is completed.

Granted: 1981-01-27
Abstract: IMPROVED SUPPORT ASSEMBLY FOR A CIRCUIT-INTERRUPTING DEVICE ABSTRACT: An improved support assembly for a circuit-interrupting device is disclosed. The device is of a type having first and second end fittings which define a major axis and which are selectively engageable and disen-gageable from matching first and second mountings spaced apart in the assembly in insulated relation. The device can be manipulated by a hookstick selectively attachable to the first end fitting and held by a human operator, and so manipulated as to selectively engage and disengage the end fittings and their respective mountings and to open and close the device. The second mounting has a noncircular pin which can be slideably received in a slot in the second end fitting only when the second end fitting and the device are in one particular orientation. The slot contains an enlarge-ment which permits the second end fitting to rotate in the second mounting once the pin enters the enlargement. When the pin is in the enlargement, the device is freely rotatable to both the closed position and the opened position. A cradle, provided on the second mounting for supporting the device, is utilized at two times. First, the cradle supports the device when the second end fitting is being engaged with the second mounting. It performs such support function to automatically place the second end fitting in the one orien-tation in which it may slideably engage the end fitting. Second, the cradle arrests rotation of, and supports, the device following an opening operation during which the first end fitting is disengaged from the first mounting. Such arresting and support function also automatically aligns the pin in the slot so that the device may be removed from the second mounting.
