Abstract: The yarn feed device for textile machinery comprises a yarn assist wheel (2) the outer surface of which is half-covered with rubber to provide axial zones (3) and (4) of relatively high and relatively low frictional characteristics. The wheel is driven by an electric motor (1) at a speed in excess of the maximum estimated demand rate of yarn by associated textile machinery. A yarn tension device (8) is provided on the yarn infeed side to the wheel, and a yarn tension device (13) is provided on the yarn outfeed side. In use the yarn is placed in contact with the surface of the rotating wheel, and can be placed against the low friction surface (4) or the high friction surface (3) by a tension-responsive yarn shipping lever (5) that is responsive to the tension in the yarn between the infeed tensioning mechanism (8) and the wheel (2). When a demand for the yarn exists, the tension in that particular section rises and the yarn is placed on the higher frictional portion of the wheel for assisting its motion towards the knitting machine. The device of the invention enables demand feeding to be provided at substantially constant and very low tension to sock machines which have widely varying and erratic demands for the yarn, and with a very wide range of different yarn types.

Abstract: This invention relates to transparent materials that are capable of absorbing liquids, and, more particularly, to materials that can be used as ink-receptive layers for transparent imageable materials. Transparent materials that are capable of absorbing significant quantities of liquid, while maintaining some degree of durability and transparency, are useful in contact lenses, priming layers for aqueous coatings, fog-resistant coatings, and transparent imageable materials for use in mechanized ink depositing devices, such as pen plotters and ink-jet printers. Compositions useful as transparent liquid absorbent materials have been formed by blending a liquid-insoluble polymeric material with a liquid-soluble polymeric material. A problem that frequently arises in the formulation of polymer blends is the incompatibility of the polymers being blended. It is well-known that polymeric materials having widely differing properties generally tend to be incompatible with one another. When attempts are made to blend polymers that are incompatible, phase separation occurs, resulting in haze, lack of transparency, and other forms of nonhomogeneity. This invention provides a liquid-absorbent composition comprising (a) a polymeric matrix component comprising crosslinked silanol moieties, and (b) a liquid-absorbent component comprising a water-absorbent polymer, preferably a water-soluble polymer. This composition is capable of forming liquid-absorbent, semi-interpenetrating polymeric networks, which are capable of absorbing significant quantities of those liquids that are solvents for the uncrosslinked portion of the network without loss of physical integrity and without leaching or other forms of phase separation. The compositions of this invention provide polymeric matrices which result in transparent coatings capable of providing improved combinations of ink absorption and durability, while at the same time retaining transparency and being amenable to the types of processing commonly used in producing transparent graphical materials.

Abstract: Des images de toner multicolores sont produites sur une surface réceptrice en superposant des images de toner d'une seule couleur produites de manière électrostatique sur un élément image (1) de façon qu'elles soient alignées sur une surface réceptrice. La surface réceptrice est tournée au moyen d'un élément de transfert (5; 60; 211), de sorte qu'elle est à plusieurs reprises mise en contact de transfert avec l'élément image. Afin d'améliorer le transfert et d'éviter l'usure de l'élément image, l'élément de transfert est activé par l'élément image au cours du transfert. Afin d'améliorer l'alignement, l'élément de transfert est séparé de l'élément image entre les transferts et réindexé. Un moteur pas à pas (17;117) est utilisé pour ce réindexage. Cette invention convient en particulier aux transferts utilisant la chaleur, en particulier à une surface de feuille réceptrice pouvant être ramollie à la chaleur.

Abstract: A system for executing instructions of a PC in which a special purpose processor (15) and a general purpose processor (11) execute the instructions sharing processes with one another. When the special purpose processor (15) reads out particular instructions (A, C) it writes the address of the particular instructions (A, C) into a buffer region (16g), and leaving them as they are, continues the execution of sequential instructions. Therefore, without stopping the execution of the sequential instructions the special purpose processor can continue it. The general purpose processor (11) executes the particular instructions referring to the buffer region (16g), while executing the system program, for example. Therefore, the general purpose processor (11) can perform the execution of the system program, etc, without being disturbed, for example, by the interruption by the special purpose processor (15).

Abstract: A single-screw compressor has a rotor (2) with screw vanes (3) which is rotatably incorporated in a casing (1). The screw vane (3) has a confronting surface (31) which has a width in a rotating direction of the rotor (2) and which faces an inner peripheral wall (11) of the casing (1). A rib (6) narrower than the width of the confronting surface (31) is formed at one end in a widthwise direction of the confronting surface (31), extending along the spiral of the screw vane (3). Accordingly, a gap between the screw vane (3) and the inner peripheral wall of the casing (1) is made small, improving sealing properties. A rib-side lateral surface (32, 33) of the screw vane (3) is effectively utilized as a heat radiation surface, so that heat generated through contact between the rib (6) and the inner peripheral wall (11) of the casing (1) is radiated easily, thereby restricting the temperature rise of the screw vane (3) as well as the thermal expansion in the radial direction thereof.

Abstract: An optical system including a scan disc (42) having concave reflectors (44) thereon is described. As an optical printer, positioned adjacent to the scan disc are a corrector lens (46), a strip mirror (48), and a primary mirror (50). Positioned adjacent to the image plane are a field mirror (52) and a pick-off mirror (50). Input light is directed onto the scan disc perpendicular to the plane of rotation. When one of the concave reflectors on the rotating scan disc is centered over one end of the strip mirror, the input light is brought to focus and is redirected to the primary mirror by the strip mirror. The primary mirror forms an image of the light spot after passing through the corrector lens. This image is intercepted by a field mirror which forms a final image of the spot. This image is picked out of the incident light beam by a thin pick-off mirror which redirects the light allowing image accessibility. With minor modification the optical system may also function as an optical scanner.
