Abstract: Abstract of the Disclosure A toy comprising a very light ball in a tube.          One end of the tube is for placing to the lips to blow toward a cup fixed at the opposite end.  The cup has a concave surface which receives the ball which extends over less than half its surface.  When the ball is placed beneath the cup and held in contact with it, in a steady stream of air expressed from the cup, the ball is trapped by the air stream and remains in close proximity to the cup.  Preferably, the clearance between the ball and the curved surface of the cup is greater at the center of the cup.  Preferably also air is expressed from a central port which is relieved or chamfered in one section in order to bias the escaping air, causing the ball to spin.  The cup may be asymmetrically located about the port such that it is canted in the direction of the relief or chamfer so that the escaping air follows a slightly longer path before it escapes from the lip in said one direction than in the other direction.

The diaphragm operator (22,118) opens. the port to balance the pressures in the input (26,122) and output (20,116) chambers when the change in input pressure or vacuum is both greater than the bias force of the spring and too sudden for rapid dissipation through the fixed orifice (30,126). At pressure changes less than the bias force of the spring (46,140) or at such a gradual rate as. to dissipate through the orifice (30,126) the valve will operate as a standard delay valve.

Abstract: DUAL FUNCTION ERROR CORRECTING SYSTEM     Abstract A dual function cyclic code error correcting method and system are disclosed for correcting from a single syndrome byte a random single-bit error which occurs in a multi-byte data word or, alternatively, correcting a multi-bit error in one byte of the data word by pro-viding an indication of the location of the byte in error, and employing the same syndrome byte to deter-mine the error pattern of the multi-bit error so the multi-bit error can be corrected.            The method involves non-zero syndrome processing steps which comprise a first series of steps which function to determine if the non-zero syndrome correlates to a 1-bit error in one of the byte positions of the data word being protected, and if so, to automatically correct the single-bit error by processing the entire byte containing the single-bit error.  If no correla-tion of the syndrome byte is established with a single-bit error, then the byte position in the data word of the multi-bit error is used during a second series of steps to process the same non-zero syndrome byte to determine the pattern of the multi-bit error in the defective byte so that the pattern can be employed to correct the defective byte.            The method and apparatus disclosed also identify the location of repetitive multi-byte errors by generating a byte parity vector for each data word and using these byte parity vectors to identify the location in each data word of repetitive errors of the multi-bit type.

Abstract: ABSTRACT   Sheet feeding apparatus including a cylindrical tube mounted above a stack of documents for separating individual documents from the stack. The cylindrical tube houses a rotatably mounted shaft to which are secured a series of spaced beater and turbine blades respectively. The cylindrical tube defines a series of apertures along its bottom surface which are aligned with the beater blades and allow the beater blades to extend outwardly into contact with a separated sheet. At one end of this cylindrical tube is coupled a vacuum source which when energized rotates the turbine blades and reduces the pressure inside the tube. Accordingly, a single sheet is first separated from the top of the stack by attraction toward the reduced pressure inside the tube and once separated is driven away from the stack by the beater blades mounted to the rotating shaft.

Abstract: APPARATUS AND METHOD FOR SNAP-SEPARATION    OF WEB MATERIAL     ABSTRACT     The apparatus of the present invention includes three winder rolls which guide a web of material on to a core, wind the web around the core to form a log of material, and then move the log away from the web with a snapping action 80 as to separate the web of material.  The rolls are separately driven so that the peripheral speed of the rolls may differ with respect to each other.  The space between two of the rolls pro-vides a throat through which a core may be moved and in which the web of the material may be restrained be-tween the core and one of the rolls.  The speed of the other two rolls is modified to move the log of material away from the throat to cause a snap-separation of the web material between throat and log.  The speed of the second two rolls may be further differentially-con-trolled so as to cause the log of material to move, selectively, away from the throat and back toward the throat, as desired, to provide a loop of web material which may be pinched between the core and one of the rolls.
