Abstract: Abstract of the Disclosure A mail handling system and apparatus accepts randomly arranged mail, determines the location of postage indicia on individual pieces and feeds the pieces to separate conveyors in response to the determination of indicia  location to orient the same and enables combining the conveyed mail pieces so that the indicia thereon appears entirely on one edge.  Feed rollers singulate and feed randomly stacked mail past indicia detectors to a positionable chute-like receptacle which is positioned in response to the detection to eject and direct mail pieces to separate conveyors depending upon whether indicia is present adjacent the right or left edge of the piece as it is presented.          The conveyors unite to provide a mail output stream with all indicia either adjacent the leading or trailing edge of the moving piece.  In the event that it is desired to have the indicia all adjacent either the upper or lower edge of each piece in the stream, it is possible to provide suitable detectors and a 180° reversal station so that pieces having the indicia thereon in the "wrong" position may be inverted to bring all indicia into essential alignment.

Abstract: ABSTRACT Servo apparatus for controlling position and movement of a transducer over information tracks recorded on a movable record medium and containing pre-recorded servo information which when read by the transducer generates servo signals, comprises control means arranged to receive the servo signals and to generate a position error signal therefrom indicative by its magnitude and polarity of the degree and direction of off-set of the head from the on-track position.  The position error signal is supplied during track following operations to an actuator mechanism connected to the transducer so that the actuator mechanism is energized in response to the position error signal to move the transducer in a direction to reduce the off-set of the transducer from the on-track position.  The control means is further arranged during track access operations to sample the servo signals from the transducer at times calculated to coincide with the on-track positions of the transducer moving across the tracks and to supply position error signals derived from the sampled servo signals to the actuator mechanism which is energized in response thereto to change the velocity of the trans-ducer across the tracks by an amount determined by the position error signals.

Abstract: TITLE APPARATUS FOR FACILITATING SEPARATION OF PEEL FROM FRUIT            ABSTRACT OF THE DISCLOSURE         An apparatus for facilitating separation of peel from fruit in which the fruit is sequentially loaded into a plurality of pockets extending around the circumference of a vertical, ro-tating reel.  The reel is mounted in a tank holding a caustic treating solution so that the fruit in the pockets is carried downwardly into the solution as the reel rotates.  Incoming fruit is conveyed into a receiving tank containing the solution so that the solution cushions the fall of the fruit from the conveyor.          The solution is heated and recirculated into the receiving tank thereby carrying the fruit over a weir and into the pockets in the reel.  The. pockets are formed by a plurality of spaced apart paddles or dividers extending from a relatively large hub to the outer periphery of the wheel.  The inner portions of the paddles are perforated so that the solution flows between pockets and through the fruit which, being less dense than the solution, is urged toward the hub by buoyant forces.  The caustic solution passing about the fruit agitates the fruit to assist in loosening the peel from the fruit.

Abstract: BOTTLE ORIENTATION UNIT     ABSTRACT OF THE DISCLOSURE     An infeed conveyor, including a pair of opposed and spaced belts coacting with the opposed sides of bottles passing there-between, moves bottles onto the main conveyor of a bottle orienta-tion unit which rotates through 180° any of the bottles not pro-perly oriented according to the disposition of a handle, label or other criteria, so that all bottles leaving the unit are identi-cally oriented for subsequent processing.  The main conveyor, of conventional chain conveyor type construction with moving flights disposed beneath the bottles, transports the bottles to and through a bottle turning station.  Upon entering the station one side of the neck of the bottle moves into contact with a stationary pad while the opposed side of the neck of the bottle is engaged by a belt moving in the direction of bottle movement but at twice the speed of the main conveyor.  The combination of the stationary pad and a belt moving at twice the speed of the bottle, coacting to-gether upon the bottles neck result in a velocity on the bottle, in the direction of bottle movement, which is equal to the ve-locity of bottle movement.  That is, the gradient of velocities between the stationary pad and the belt travelling at twice the speed of the bottle is a straight line gradient.  Thus a bottle has no speed change imparted to it; but only a pure torque acting upon the bottle to turn the bottle in a predetermined manner and direction.     Every bottle, thus subject to the turning action, is urged to turn about an axis of rotation through the neck of the bottle as the bottle passes through said turning station.  A gate unit dis-posed at the turning station, however, when in a forward position coacts with the units frame to define a path which is only wide enough for the bottle to pass through, but not wide enough to per-mit the bottle to turn.  Accordingly, the torque action upon the bottle produces a slippage and the bottle is not re-oriented.          When the gate unit is in a retracted position, however, the path is widened and the torque action upon the bottle results in the bottle turning 180° and being re-oriented.  A hold down belt acts upon the top of the bottle to urge it against the main conveyor and stabalizes the bottle as it passes to and through the turning station.    Suitable electrical controls, disposed and designed to sense the orientation of each bottle, are triggered by other controls which sense that the bottle neck is in a particular location with respect to the turning station.  The output of the orientation sensing controls, in conjunction with the output from a control for sensing the positioning of the gate, determine whether the gate is to be moved from its current location and thus whether a bottle is to be turned or not.

Abstract: ABSTRACT The present invention relates to raise-type earth boring drills and more particularly, to rais drills having shock elements for absorbing bending loads passing through the drill.  During a raise drilling opera-tion, a tremendous amount of wear and stress is imposed upon the raise bit and upon the drive stem thereof.  Removable drive stems are used to extend the useful life of the bit, but a certain amount of down time is still required to remove and replace the stem.  This non-operating time is costly and it is preferable to obtain as long a running time as possible for each bit-stem combination.  One area that has not been sufficiently explored in raise drilling is the area relating to improving the operating life of a raise drill drive stem.  The present invention accomplished this by providing a shock element in the drill for absorbing the uneven bending and impact type loads on the bit in order to prevent them from being transferred to the drive stem.  The raise-type drill according to the present invention includes a drive stem attached to a thrust bearing support plate which, in turn, is interconnected to a main bit body. The interconnection is accomplished on an elastomeric shock element which functions to transfer the thrust and torsional loads from the drive stem to the bit body while absorbing the bending loads passing therethrough.

Abstract: Abstract of the Disclosure The invention relates to a monopulse radar apparatus for the auto-matic angle tracking of a moving target, whereby angle tracking errors, incurred if the polarisation of the received signals is orthogonal to the polarisation of the radar receiver, are prevented.  The monopulse radar there-to comprises two monopulse clusters tuned to the same frequency band but attuned to receive mutually orthogonal polarisations; only one of these clusters lends itself for the transmission of r.f. signals.  On the supply of sum and difference signals from the two clusters, the receiver produces the angular error signals required to keep the radar directed at the target.  These error signals are determined by the amplitude ratio between the difference signals and the sum signal from the first cluster or by the amplitude ratio between the difference signals and the sum signal from the second cluster, depending on the ratio between the sum signals from the two clusters.
