  • Patent number: 4558467
    Abstract: The present invention discloses a gastight seal for rubber suits. It incls rubber bladders containing viscid material and has annular rings attached to a pleated bellows-like section of a main body of the rubber suit. A strap is used to actuate the rubber bladders which interlock the annular rings which join two sections of the main body of the rubber suit. Thus, an integral gastight seal on the rubber suit section is achieved.

  • Patent number: 4547933
    Abstract: High strength, high modulus, continuous filament aromatic polyamide yarns are stretch broken under high tension while being sharply deflected in a lateral direction by mechanical means to provide a sliver which is processed by conventional means to a high strength, high modulus spun yarn. The broken ends of the fibers are highly fibrillated to fibrils having lengths of 50-350 times the diameter of the unfibrillated portion of each fiber.

  • Patent number: 4547905
    Abstract: A shoulder pad construction in which outer plastic shells are held off of the shoulders by rigid underlying arches so that the pad is supported entirely on the chest and back rather than on the shoulders. The opposite ends of the arches are secured to the breast plates and back plates of the shells. Padding for the shells has thick front and back portions which contact the chest and upper back. Bridge portions of the padding are much thinner to avoid impacting the acromio-clavicular joints and are cut back away from the trapezius muscles at the base of the neck to avoid applying pressure to the brachial plexus. Forces applied to the shoulder pad are partially absorbed by the shells and are transmitted to the thick padding areas and to the chest and back without applying pressure to the shoulder or to the acromio-clavicular joints or trapezius muscles.

  • Patent number: 4546497
    Abstract: The invention provides antistatic clothing suitable for wear in a room which is kept clean. The clothing, such as working clothes, work shoes, etc., manufactured from a cloth having parallel electroconductive fibers woven therein, features the incorporation of an electroconductive material at overlapped or butt-joined seams between the pieces of cloth forming the clothing to ensure a perfect electrostatic connection of all the pieces of the clothing to minimize static charging on both the clothing and the wearer's body while preventing dust from gathering on the clothing to avoid dust from becoming a cause of problems such as electrostatic breakdown of circuit elements in a semiconductor integrated circuit production plant.

  • Patent number: 4539729
    Abstract: Fiber slivers must be condensed during the course of a spinning process or their mass must be determined. For this purpose there are employed so-called grooved pairs of rollers, that is to say, profiled rolls which define a sliver throughput groove which is limited or confined at both sides. The sliver is guided through a feed or delivery funnel up to the throughput groove. The danger thus exists that individual fibers can jam between the side surfaces or faces of the rollers which form the lateral boundaries of the groove. This danger is eliminated with the invention in that the fiber outlet opening of the feed funnel is located within the region of a wedge-shaped gap which is bounded by an overlapping zone of the side surfaces or faces of the rollers.

  • Patent number: 4540108
    Abstract: The invention is a tool for use in grasping yarn during the making of needlepoint with a mesh having openings through which yarn is stitched including a handle having first and second ends located on a longitudinal axis; a member extending from the first end of the handle along the longitudinal axis; and a yarn grasping head joined to an end of the member at a position remote from the first end of the handle, the yarn grasping head having first and second bifurcations extending in the direction of the longitudinal axis, the bifurcations respectively having first and second ends and being joined together at one end to form a vertex for grasping yarn in the vertex, the bifurcations being spaced apart from each other by a substantially constant distance along the longitudinal axis except in proximity to the vertex to form an opening through which yarn can pass for grasping within the vertex, each bifurcation being deflectable to permit deflection toward the other bifurcation when engaging an opening in the mesh

  • Patent number: 4528722
    Abstract: In a card, to avoid passage of fibers or fiber flocks over the edge of clothing into a gap, a covering band is pressed against an internal surface of the fiber-guiding roll or cylinder and a surface lying opposite the fiber-guiding roll. The covering band covers the gap between the fiber-guiding roll and a side wall portion. Two forwarding grooves, lying opposite one another in the gap and having transport surfaces lying opposite one another in crossed fashion, return fiber flocks which may possibly pass into the gap to the upper surface. A forwarding pin is set into the roll surface 7 of the fiber-guiding roll outside the edge of the clothing at such a inclination that fibers or fiber flocks which can pass into this region are transported by such pin towards pointed clothing of card flats.
