Abstract: DIRECT KEYBOARD CONTROLLED RACK SHIFT DEVICE            FOR A SINGLE ELEMENT TYPEWRITER                         Abstract A device is disclosed for shifting a bifurcated rack from one position to a second position, thereby engaging alternate sides of a bifurcated rack member with a pinion in a spacially fixed position.  The rack shift mechanism. is controlled by a direct link to the keyboard of the typewriter which responds to movement of a shift key lever.  The mechanism performs a force multiplication and, at the same time, a displacement division function to reduce a relatively large key lever and link displacement to a relatively small rack displacement with a corres-pondingly higher force factor.  The force multiplication linkage translates the rack of the rack/pinion pair to engage the alternate portion of the rack, thereby reversing the rotation of the pinion and allowing the selection from the opposite hemisphere of the type element in response to a selection output.

Abstract: APPARATUS FOR FUEL VAPOR RECOVERY            ABSTRACT OF THE DISCLOSURE     A filler neck assembly is mounted to a fueling port at one end and to a fuel tank through a tank entry nipple at the opposite end, which assembly provides a fuel path into the tank and a vapor recovery path out of the tank while being serviced from a fuel dispensing nozzle having vapor recovery means.  The filler neck comprises a fuel delivery tube connected to the fueling port and to the inside of the tank through a baffle within the tank entry nipple.  The baffle securely seats the tube within the tank.  The fuel delivery tube is coaxially mounted within the bore of an outer tube having ribs on the inside surface of its bore, the outer tube also being connected to the fueling port and to the tank entry nipple.  In a second embodiment the ribs are on the outside surface of the inner fuel delivery tube while the bore of the outer tube is a smooth surface. In either embodiment the tubes are connected to the fueling port and to the inside of the tank entry nipple and the re-lationship of the two tubes and the tank baffle is such as to provide a vapor path between the tubes from the tank to the dispensing nozzle vapor recovery means via the valleys defined by ribs such that the vapor may be returned to the source supply of fuel.

Abstract: MATERIAL CONVEYING APPARATUS            ABSTRACT OF DISCLOSURE:    A livestock feeding apparatus having an endless belt sup-ported on an elongated table above a feed bunk by a plurality of stands.  The stands are laterally and vertically adjustable to level the apparatus and accommodate different sized bunks.          The belt has an upper run that rides on a wood deck.  An idler pulley engages one end of the belt and a drive pulley engages the other end of the belt.  The belt is retained in driving engagement with the drive pulley by a driven roller engageable with the lower run of the belt.  A motor operates to drive the roller at a speed so that the surface speed of the roller is greater than the linear speed of the belt to maintain the lower portion of the run of the belt between the roller and the drive pulley under tension.  A sweep assembly operates to move the material off of the side of the top run of the belt into the bunk.  The sweep assembly has a roller located in driving engage-ment with the upper run of the belt and an angularly located drum.  Coacting drive members drivably connect the roller with the drum so that on rotation of the roller the drum is rotated to move material off the side of the belt.  A reversible motor drivably connected with a cable to the sweep assembly operates to reciprocate the sweep assembly.  A belt tightening assembly is associated with the pulleys on the opposite ends of the table to maintain the belt under tension.  A diverter assembly attached to the sweep assembly has a pivotally mounted chute which can be moved to opposite inclined positions to selectively direct the material to opposite sides of the feed bunk.

Abstract: ABSTRACT     Hydraulic control apparatus for parallel-connected double-acting cylinders enables the associated pistons to extend and retract together substantially uniformly.  Mounted in a soil working implement such as an agricultural cultivator having a spaced array of soil-working tools whose working position is controlled by parallel-connected cylinders, the hydraulic control apparatus enables substantially uniform depth of soil penetration by all the tools in the array.  A flow control valve for each cylinder is connected in one of the hydraulic fluid connecting lines to the cylinder.  The flow control valves for all the cylinders are oriented so that uniform extension or retraction, as the case may be, of the associated pistons is obtained.  If both extension and retraction are to be controlled, a pair of flow control valves is provided for each cylinder, one controlling extension and the other retraction.  The invention also includes an implement such as a soil-working implement provided with such hydraulic control apparatus.

Abstract: Abstract of the Disclosure A device (10) for unloading particulate material from circular storage bins (11) having central discharge sumps (13).  The device (10) includes two augers (18, 20) extending radially in diametric opposition from a vertical pivot axis adjacent the discharge sump (13).  The augers (18,20) are powered to pivot forwardly about the vertical axis and are also rotated about longitudinal auger axes to engage and move particulate material toward the vertical axis and into the central outlet sump.  A central counter rotating auger drive means (16) is powered to rotate the augers in opposite directions.  The counter rotating drive means (16) includes a single input drive shaft (30).  The single input shaft (30) rotates two worm gears (31,35) of a transmission means.  Two worm wheels, (32,36) each attached to a respective auger, mesh with the worm gears (31,35).          The worm gears (31,35) and worm wheels (32,36) function as gear reduction units to transmit rotation of the input shaft (30) to opposite geared down directional rotation of the au-gers.  The single input drive shaft (30) is also operatively connected to a hydraulic pump (37).  Fluid under pressure from the hydraulic pump (37) is delivered to outbound drive wheel assemblies which, in turn, pivot the auger units for-wardly about the vertical axis.  Splash guards (48) are mount-ed to the auger assemblies, facing forwardly to engage and direct material downwardly toward the augers.

Abstract: DATA COMMUNICATION SYSTEM                 ABSTRACT       A data communication system for use in the control and monitoring of mobile stations, for example, in a bus monitoring system, from a central station over a communication channel carrying both data and voice information.  Information is encoded into digital messages having a start code followed by one or more data blocks.  The start code identifies the beginning of the data block that follows and enables syn-chronization of clock circuitry to the received data frequency. The data blocks have N digital words with M binary bits where one word is a parity word and N-1 words are data words.  Each of the data words has a data portion and parity portion coded for correction of at least one error.  Relia-bility is enhanced by a data detector which discriminates between data and noise or voice to provide an indication of the presence of data.  In transmitting the digital messages, the bits of the N words in each data block are interleaved to provide protection against error bursts.
