Abstract: A method of redirecting a glass ribbon assembly from a first glass conveyance path to a second. The method includes conveying the glass ribbon assembly that includes includes a flexible glass substrate that has first and second surfaces that extend laterally between the edges, and first and second handling tabs affixed to the respective edges. The handling tabs extend above and below the flexible glass substrate and define a handling surface envelope. The method also includes supporting the glass ribbon assembly on the first and second handling tabs such that the flexible glass substrate is free to flex out of the handling surface envelope while remaining spaced apart from a primary roll member when the flexible glass substrate is directed around the primary roll member.

Abstract: A system and method for propelling a hose, including: a system housing and a tractor element disposed in the housing. The tractor element includes: a tractor housing with a through-bore; and a protrusion extending into the through-bore. The system includes: a hose assembly including a substantially helical coil disposed about a hose; and an actuator for rotating the tractor housing with respect to the system housing. The tractor element is fixed in the system housing with respect to axial movement; and the hose assembly can be disposed in the through-bore so that the protrusion contacts a portion of the coil. As the tractor housing is rotated in a rotational direction: the protrusion exerts a displacement force on the coil; and the hose assembly reacts to the displacement force by displacing in an axial direction.

Movement of the stylus along the slot advances the wire marker to the proper position for cutting.

Abstract: A two piece feed member providing a less costly replacement and the ability to adjust the feed member's length. The two piece configuration only requires that the wearing portion be replaced, and not the entire feed member. This allows for a significant cost savings. Different feed mechanisms require different length feed members, and therefore, an adjustable length feed member allows for the use of one universal feed member.

Abstract: An apparatus for feeding an elongate surface tape or a strip of piled, plushed or tufted textile along a predetermined path has a drive roller which has a multiplicity of wire bristles planted in its surface for releasable engagement with the strip. Disposed upstream of the drive roller with respect to a predetermined traveling direction of the strip, an idler roller is also provided with a multiplicity of wire bristles for releasable engagement with the strip. The idler roller is constantly braked to hold the strip under tension as it extends over the two rollers. The wire bristles on the rollers may be either straight or bent and may either extend radially of the rollers or be inclined in prescribed directions with respect to the traveling direction of the strip.

Abstract: An electronic component transporting apparatus employing taping cassettes includes a toothed wheel arranged for meshing engagement within successive compartments of a taping cassette after a sealing tape has been stripped from the taping cassette and components contained in compartments thereof have been successively removed, whereby stepwise rotation of the toothed wheel is utilized to produce stepwise advancement of the taping cassette for successive removal of electronic components contained in the compartments. Since it is not necessary to provide a line of perforations along an elongated side of each taping cassette, for use in driving the cassette, each cassette can be made substantially smaller in width than has been possible in the prior art.

Abstract: A feed control device for use in conjunction with plumbing tools of the type used for cleaning and removing obstructions from waste lines in which an elongated coiled spring wire, or plumber's snake, is advanced through the pipe and rotated. The feed control device includes a novel snake feeding mechanism movable into and out of engagement with the snake and includes a biasing means for yieldably urging removably mounted feed rollers, which form a part of the feeding mechanism, into driving engagement with the snake. A unique feature of the invention resides in the design of the feed roller holder assembly which permits the selection of rollers having either smooth peripheral surfaces, or, alternatively, surfaces having helical grooved formed therein. When the smooth rollers are used the rollers can be rotated within the holder assembly so that the snake can be driven forwardly or in reverse.

Abstract: A system of forming and manipulating primary cell separator basket preforms produced in strip form and tandem relationship with a dentent associated with each preform, e.g., a transverse slit in the strip for each preform displaced so its edge is outstanding from the generally flat strip.

Abstract: An improved process for making disposable diapers, and the like, having hook-and-loop fastening systems, and disposable diapers made by the improved process. The loop structure of the hook-and-loop fastening system used in this invention is substantially free of article attachment adhesive and comprises loop elements affixed to a support structure. The loop elements are deformed when the loop structure is wound onto a parent roll. At least a portion of the deformed loop elements are restored to essentially their original, undeformed, state after the loop structure is unwoundfrom the parent roll. The restoration is accomplished by contacting the loop elements with a mechanical restoration device which comprises either a brush or a scarfing surface. The brush preferably has a plurality of bristles having an average free length greater than about three times the average undeformed height of the loop elements and an average bending modulus less than the average modulus of elasticity of the loop elements.
