Abstract: Abstract of the Disclosure Apparatus for recovering hydrocarbons from an air-hydrocarbon vapor mixture of the type including a pair of alternatively used carbon bed absorbers which are used to remove hydrocarbon vapors from the mixture and which are desorbed of hydrocarbons by subjecting the beds alternatively to vacuum regeneration using a vacuum pump the output of which is passed through an absorber using liquid gasoline as the absorbent liquid.  The efficiency of the process is increased by interrupting the flow of the absorbent liquid during the initial period of the regeneration during which period the hydrocarbon vapor content of the mixture is low due to the fact that a substantial vacuum is required to separate the hydro-carbons from the carbon bed.

Abstract: BALL BUSHING            ABSTRACT OF THE DISCLOSURE        A ball bushing for mounting on a shaft is dis-closed which is freely movable relative to the shaft in both axial directions as well as in one direction of rotation and which is sluggishly movable in the second direction of rotation, but without locking.  The ball bushing includes a sleeve made of a deformable material. Closed channels are defined in the sleeve, each having two axially extending portions connected at both ends by curved portions.  One axially extending portion contains a row of load-bearing balls, adjacent to which is a steel needle.  The steel needle is positioned so that the cen-ter point of each of the load-bearing balls is positioned to one side of the line through the axes of the shaft and the needle, that side being toward the second axially extending portion of the same closed channel.  Therefore, the lines connecting the axes of the shaft and needle to the center point of each of the load-bearing balls form an angle, the angle being preferably between 174° and 178°.  The angle may be constant for all the load-bearing balls, or may decrease toward the ends of the needle. The needle may have a diameter which tapers down from its center towards its ends.

Abstract: ABSTRACT OF THE DISCLOSURE       The end of an axle spindle is provided with right hand and left hand threads to receive respective axle nuts.  The inner nut thread diameter is larger than the outer nut thread diameter in order to avoid interference.  The wheel, bearings and an inner nonrotatable washer on the axle spindle are secur-ed in place by tightening the inner nut to an initial snug (no clearance) condition against the face of the nonrotatable washer.          One of eight holes on the outer face of the inner nut receives a projecting pin of a spacing control device which pin projects a predetermined distance.  The outer nut is turned until the spacing control device engages one of the eight recesses.  Then the flats of both nuts are tightened by a spanner wrench which causes the inner nut to "back off".  The method is to create a space between nuts (e.g. by use of a shim spacer) which converts to an appropriate clearance space between the inner nut and nonrotatable washer in the final condition and to maintain that space in the final condition.

Abstract: ABSTRACT OF THE DISCLOSURE           Apparatus for recording or reproducing both digital and analog signals on or from respective substantially concentric recording tracks on a rotating magnetic disc with only digital or analog signals being recorded in any one of the tracks comprises a transducer mounted in substantially contacting relation to the magnetic disc for recording or reproducing the digital and analog signals on or from the tracks, a motor coupled to the transducer for moving the transducer radially with respect to the magnetic disc, a track status memory for storing track ID (identifying) information for each of the recording tracks and producing a track classifying signal corresponding thereto, and a level detecting circuit for detecting levels of signals reproduced from the tracks and producing a level indicating signal corresponding thereto.  A control is jointly responsive to the track classifying signal and the level indicating signal for controlling the motor so that it positions the transducer in closed-loop servo tracking relation to a given track on the basis of the level indicating signal when the track classifying signal indicates that the given track or at least one track adjacent thereto contains an analog signal and otherwise effects open-loop positioning of the transducer regardless of the level indicating signal.  This enables accurate reproduction of the analog signals coupled with rapid access to the digital signals.

Abstract: ROTARY CONVEYOR APPARATUS                ABSTRACT OF THE DISCLOSURE     A conveyor comprises a plurality of rotors spaced longitudinally along a conveyor frame, each rotor having a rotatable shaft on which is fixed a number of axially spaced discs.  The discs are staggered laterally of the conveyor and are of such diameter that the discs of adjacent rotors overlap one another.  Each disc has at least one notch in its periphery, but the remainder of the peripheral surface is smooth.  The notches of the discs of each rotor are adapted to support a workpiece and transfer it from one rotor to another in response to rotation thereof.  A barrier is mounted between each adjacent pair of rotors to prevent transfer of a workpiece from one set of discs to another unless the workpiece is properly seated in the notches of the upstream rotor.  Each rotor has a clutch assembly connecting it to a continuously operable driving motor, thereby enabling any rotor to cease rotation without stopping the motor.
