Abstract: Abstract of the Disclosure An apparatus for peeling off the leading edge of a sheet of paper adhering to A a moving transfer image carrier during the process of transferring a powder image onto the sheet.  The apparatus includes one stripper member or a plurality such as three stripper members mounted in the vicinity of the transfer  image carrier at the side on which the sheet is intended to be detached from the same.  The one or several stripper members engage the moving sensitive surface of the image carrier at a balanced extremely low contact pressure and are adapted to be lifted off this surface by a peeled-off sheet of copying material.  The strippers are continuously reciprocated in a direction transversely of the transfer image carrier and thereby like-wise transversely of the advancing sheet so that the problem of traces that may be engraved into the surface of the transfer image carrier is virtually overcome and the useful life of the image carrier is substantially extended.

Abstract: FUNNEL ARM OPERATING MECHANISM             ABSTRACT OF THE DISCLOSURE          In apparatus for molding glass into hollow-shaped articles such as glass containers, glass charges are delivered to a parison mold wherein the glass is shaped either by a plunger or by a counterblow within the parison mold.  The charge of glass that is delivered to the parison mold is guided into the mold by a superimposed funnel.  The funnel is alter-nately moved into and out of position at the open, upper end of the parison mold to effect the guiding of the charge.  The mechanism for moving the funnel on a conventional I.S. machine must be capable of moving the funnel from an upper, radially displaced position, to a lower, seated position concentric with the mold.  The operation of the funnel seating motion is accomplished by the use of a generally reciprocable, fluid-operated motor in which a funnel-carrying arm is fixed to the piston rod of the motor and the rod is turned about its vertical axis during its upward and downward movement.  The control of the fluid supplied to the motor and the exhaust of fluid from the motor is such that the rate of movement may be closely ad-justed and controlled.   The entire operating mechanism is mounted on what is termed the "section box" of the I.S. machine.  For convenience of repair and adjustment, the fluid motor is mounted to the upper end of the piston rod, with the piston rod extend-ing vertically downward.  Intermediate its length, the funnel arm is fixed to the piston rod.  The rod is turned about its vertical axis by a cam roller, carried by the arm, moving in a fixed cam slot.  The lower end of the piston rod is guided within a fixed bushing  and the upper end of the mechanism is held steady by a bracket.

Abstract: ABSTRACT OF THE DISCLOSURE An improvement is provided in a vehicle having a frame structure having wheels suitably rotatably mounted thereon, an axle extending between and fixed to an associated pair of wheels for rotation therewith, the axle serving as a rotatable driver shaft, an electrical generator provided with an outer housing and a rotor within the housing, and a drive apparatus for the generator comprising a driver sheave carried and driven by the driver shaft, a driven sheave fixed to the rotor, and belt means operatively connected between the drive sheave and the driven sheave. The improvement comprises a support structure affixed to the frame structure, preferably including a telescoping member adapted to be received in telescoping relation within the frame structure, an adjustable pivot support supporting the generator on the vehicle, the adjustable pivot support comprising a pin carried by the support structure, preferably the telescoping member, and a lug on the outer housing having an opening therein for receiving the pin therethrough, the adjustable pivot support enabling alignment of the generator so that the driven sheave is precisely aligned with the driver sheave, and a torsion spring yieldingly moving the generator about its pivot support, thereby moving the driven sheave away from the driver sheave and placing a substantially constant yielding tension on the belt means to assure the driven sheave and generator are driven in an optinum manner.  This invention therefore substantially overcomes the difficulty of misalignment of belt sheaves, which imposes damaging side loads on both the belts and the sheaves, and also maintains a substantially constant tension on the associated drive belts.

Abstract: ABSTRACT OF THE DISCLOSURE An electronic control for a paper stock freeness tester.  Probe-sensing means generate first and second signals when a filtrate in a filtrate chamber reaches first and second levels repectively.  Cycle control and lad-der control circuits automatically and cyclically perform tests to determine the freeness of paper stock in response to these signals.  An electronic free-ness measurement circuit uses the signals to measure accurately the time re-quired to accumulate a predetermined volume of filtrate in the filtrate cham-ber.  The freeness measurement circuit in turn, energizes a recorder to pro-vide a freeness measurement or an input control signal to an analog control network in a closed loop control system.

Abstract: ABSTRACT OF THE DISCLOSURE            The disclosure relates to a mechanism for high speed horizontal folding of fabrics, such as tubular knitted fabrics, enabling the fabric to be folded at greatly increased linear speed in relation to the prior art.  The folder apparatus includes horizontally reciprocating downfeed rollers which receive the incoming fabric and propel it downwardly, while guiding the fabric horizontally to lay it in back and forth folds of substantially uniform length.  Means are provided for reciprocating the down-feed rollers horizontally at high speed during the folding opera-tion.  Means are also provided for continuously rotating the downfeed rollers, independently of the horizontal reciprocating motion, thereof, for directing the incoming fabric downward toward the accumulating fold stack:  Reciprocating weight is held at a minimum by providing a novel external drive for the downfeed rollers, which are operative to provide a constant rate of down-feed of the fabric in any horizontal position of the downfeed rollers.  The invention also provides an optimum geometrical con-dition for the incoming fabric web, for minimizing the effects of air inertia and resistance on the rapidly oscillating fabric web.

Abstract: INTEGRATED OPTICAL WAVELENGTH DEMULTIPLEXER (IOWD) Abstract of the Disclosure An integrated optical wavelength demulti-plexer has deposited on a waveguide layer a pair of Luneburg lenses, the first for collimating light from an optical fiber, the second for focussing light at an array of photo-detectors formed under the waveguide layer.  Between the lenses is the dispersive element, a thin-film prism of a highly dispersive low-loss material such as arsenic trisulfide. A known integrated optical demultiplexer, which uses a chirped diffraction grating to spatially disperse (rather than angularly disperse) the optical wavelengths, would suffer a greater insertion loss particularly for wavelengths coupled out at a later point in the grating.  Demultiplexing with a thin-film prism should also result in the capability to handle a larger number of channels, for a given channel isolation and substrate area.                          - i -
