  • Publication number: 20040067863
    Abstract: The invention set out to improve the oxidizing and bleaching effect of inorganic peroxygen compounds in dishwashing, more particularly machine dishwashing, in terms of their storage stability. This was essentially achieved by using particulate compounds corresponding to formula R1R2R3N+CH2CN X−, in which R1, R2, and R3 independently of one another represent an alkyl, alkenyl or aryl group containing 1 to 18 carbon atoms, in addition to which the groups R2 and R3 may even be part of a heterocycle including the N atom and optionally other hetero atoms, and X is a charge-equalizing anion. Dishwashing detergents, more particularly machine dishwashing detergents, contain about 1% by weight to 10% by weight of this bleach-boosting agent.

  • Patent number: 4689945
    Abstract: The starting or re-piecing of a yarn in an open end spinning machine is accomplished during full speed rotation of the spinning unit. A travelling piecer provides a fixed length of yarn to be back-fed into the spinning unit. A control which is responsive to the speed of rotation of the spinning unit causes the nip rolls to close together in order to deliver the new yarn from the spinning unit at the operating speed of the spinning unit.

  • Patent number: 3984061
    Abstract: To prevent splatter of oil from a traverse spiral drum upon rapid rotation of the drum in high-speed spooling machines, an oil retention plate is provided extending parallel to the axis of the drum and having an oil wiping edge engaging the surface thereof, the drum being located in advance -- with respect to rotation of the drum -- of the position of the slider block engaged in a spiral groove of the rotating drum to provide for the traverse movement, the plate being of sufficient width to block spray of oil centrifugally thrown off the surface of the drum upon rotation thereof, a bead of oil being formed at the engagement edge of the drum and the plate, the bead penetrating the spiral groove in the drum to provide, due to the rotation of the drum, lubrication of the lateral surfaces of the groove and hence lubrication for the slider block while preventing contact of lubricating oil with the yarn being spooled.
