Abstract: Blending of thermoplastic polyester with fiber-forming polyamide in the production of melt-colored melt-spun fibers results in improved color strength and aesthetics, and dimensional stability.

Abstract: A composite structural material suitable, for example, as a replacement for wooden boards, is disclosed. It comprises a dimensionally stable core material ensheathed in a dimensionally stable, laminar covering that is adherent to the core material. The laminar covering is comprised of at least one layer of parallel cords (19) bonded to at least one layer of a rigidified web material (10) selected from the group consisting of paper and cloth. Suitable core materials include polyurethane foam (38), optionally filled with particles (32) of granulated rubber, expanded perlite, expandable polymer beads, and/or glass microspheres. The parallel cords (19) preferably are supplied in the form of a strip of polyester cloth, as the warp cords thereof. The web material (10) preferably is kraft paper that is rigidified with an epoxy resin.

Abstract: A shipping pallet comprised of at least one layer of substantially parallel, structural deck boards attached to a plurality of stringers is disclosed. The layer of deck boards defines a three-dimensional, substantially rectilinear deck zone that is defined by a top plane, a bottom plane, and four side-edge planes. The pallet includes at least one non-structural member that carries a readable device within the deck zone of a pallet, in the space between two structural deck boards. The non-structural member has a Modulus of Elasticity and Modulus of Rupture that are both below that of the strongest deck board in the deck zone in which the non-structural member is mounted.

Abstract: In a system for storing and retrieving cartridges, a plurality of cartridges are placed in plural slots of diverse location and orientation. A rotatable carriage contains a first and second gripping mechanism, either of which extends to engage and slidably retract a cartridge from a first storage slot into the carrriage. The carriage can rotate the cartridge to the orientation of a second slot. A vertical and horizontal transport mechanism moves the carriage to the second slot whereupon the position and orientation of the carriage with respect to the second slot is verified. The gripping mechanism then retractably extends and releases the cartridge into the second slot, whereupon the gripping mechanism retracts into the carriage. The use of a first and second gripping mechanism allows expedited manipulation and transportation of the cartridges. Sensors verify the alignment of the carriage with respect to the various slots.

Abstract: A cursor assembly for use in association with a viewing window of a microfiche viewer consisting of a first guide rail, a slide member and a reader bar projecting outwardly from the slide member. The slide member has U-shaped slipway extending longitudinally thereof. The slipway is substantially wider than the guide rail whereby the slide member may be located on the guide rail with the guide rail extending longitudinally through the slipway. A permanent magnet is carried by the slide member such that the slipway is located within the magnetic field of the magnet whereby the slide member may be magnetically secured with respect to the guide rail. The reader bar projects outwardly from the slide member and extends across the viewing window in use. The slipway and guide rail are proportioned to permit the slipway to be angularly inclined with respect to the guide rail to be angularly adjustable with respect to the guide rail to be aligned with images readable on the viewing window.

Abstract: A method for electrolytically polishing the inside surface of hollow niobium bodies in which the niobium body acting as an anode is partially immersed in electrolyte and a voltage applied at a current causing oscillations to take place to cause polishing of the niobium body, after which the voltage is disconnected and the oxide layer generated during polishing dissolved. In accordance with the disclosed invention, during the application of the constant voltage, the hollow niobium body is slowly rotated about its axis of rotation at a speed so low that the development of the damped oscillations is not disturbed, with the rotation stopped during the subsequent dissolution of the oxide layer and then a further rotation carried to immerse parts which have not been previously polished after which the steps are repeated.
