  • Patent number: 7288338
    Abstract: A binderless glass fiber mat suitable for use as a separator for valve regulated (“recombinant”) lead acid (“VRLA”) batteries is disclosed. The separator is produced by a dry process by collecting the fibers from fiberizing apparatus, without subjecting them to a wet paper making or other post forming process, and selecting portions of the collected fibers which are sufficiently uniform in thickness and grammage for use as battery separators. The fibers can be entwined to produce a superior separator material. Additives can be introduced during the collection process to enhance the properties of the separator. A battery comprises at least one stack of alternating positive and negative plates, with the separator between adjacent plates. Separators according to the invention are significantly more resilient and have longer fibers than otherwise identical separators made from different samples of the same glass fibers, but by a conventional wet paper making process.

  • Patent number: 7175604
    Abstract: A device including an elastic member and means for connecting the ends of it to a person so that the elastic strip is operable, when the person's leg is straight or nearly straight, to exert a force that tends to bend the leg at the knee and hip is disclosed. The device assists someone using the device to achieve a safe and adequate lift of his or her legs during the swing phase of the gait cycle. Prolonged use of the device has been observed to cause a person, when later walking without the device, to exhibit better leg lift during the swing phase of the gait cycle than that person did before using the device. The elastic strip can be connected at one end to a shoe insert and, at the other end, to a belt.

  • Patent number: 6971326
    Abstract: The invention concerns a tufting machine having at least one needlebar, loopers, hooks to pick up yarn delivered through the needles of the needlebar, knives to cut yarn loops and driving means, with the needle action and/or the looper action and/or the hook action, and/or the knife action being a non-simple harmonic motion. In said machine the needles, the hooks, the knives and the loopers have separate drive systems. So the motion of the needles, the hooks, the knives and the loopers can be such that first of all the pickup of the yarn or the cutting of the yarn loop can be improved. When the drive system is computer controlled more accurate machine set up can be achieved. Moreover different set ups can be achieved automatically for different products. Patterning effects are also possible.

  • Patent number: 6955865
    Abstract: A non-woven sheet of polyolefin fibers having opposed major surfaces is disclosed. Some areas of one or both of the major surfaces are hydrophilic as a consequence of an acrylic graft polymerized with the surfaces of the fibers in those areas while the fibers in other areas of that major surface are free of the graft and, as a consequence, remain hydrophobic. A battery separator composed of at least two such non-woven sheets is also disclosed, as well as batteries having a separator composed of at least one such non-woven sheet. Also disclosed is a non-woven sheet of polyolefin fibers where opposed major surfaces of the sheet are hydrophilic as a consequence of such an acrylic acid graft, but the ion exchange coefficients of the two major surfaces are different.

  • Patent number: 6846047
    Abstract: An improved wheel rim, an improved spoke nipple and an improved wheel are disclosed. The rim has spoke openings and a threaded end of each spoke extends therethrough. An internal nipple with a threaded bore is connected to the threaded spoke end so that a first, ball-shaped, rounded end of the nipple is seated on the rim. A portion of the rim around each spoke opening is deformed or removed so as to define a portion of a socket with the same curvature as the first end of the nipple. This minimizes the required diameter of the spoke opening in the rim and maximizes the area of the rim socket surface. The invention also extends to an external nipple with a rounded collar in combination with a rim including a concave rounded rim surface formed in the rim itself.

  • Patent number: 6660336
    Abstract: An improved method for producing impregnated reinforcing threads is disclosed. The method involves impregnating glass, carbon or aramid fibers with a twist ≦120 turns/m with a polymer dip, drawing the impregnated threads through a nozzle, drying the threads superficially in a first heating zone where they are kept moist in the core, and then providing them with a twist up to 400 turns/m in a second heating zone in which they are heated to fix this twist. The fibers are intimately impregnated with polymer, so that the impregnated threads have high fatigue strength, and a compact, constant cross section throughout their length. The impregnated threads are particularly suitable for reinforcing driving belts and high pressure hoses; they can be made into wovens and scrims which, in turn, can be used for reinforcing tires, conveyor belts and the like.
