    摘要： Apparatus and a method for producing a yarn, the apparatus and method comprising a reciprocating twisting stage, the reciprocating twisting stage comprising one or more twist rollers that rotate along an axis of rotation and that are arranged to move reciprocally along the axis of rotation to impart twist to one or more slivers to form twisted strands; and a drive system for one or more take up holders, the drive system arranged to have wound onto the one or more take up holders the yarn after two or more strands are twisted together to form the yarn. The drive system is arranged to drive the one or more take up holders such that the linear speed at which the yarn is wound onto the one or more take up holders can be controlled relative to the linear speed at which the strands exit the one or more twist rollers.

    摘要： A diffractive device has a surface relief structure which when illuminated by a light source, generates one or more diffraction effects which are observable from a range of viewing angles around the device. At least part of the surface relief structure is arranged in a series of tracks, each track being less than 0.25 mm in width. The device, which may be embossed onto a metallised foil, is suitable for use as an anti-forgery authentication element on valuable documents.

    摘要： Magnetic recording media including permanent structures of aligned acicular particles have been proposed as a means of identifying and authenticating a medium. A structure of such a media by which information can be recorded and read-out without interference from the structural remanence difference is described. An apparatus and method for the examination of such media for their permanent structures, particularly when used in security documents such as credit cards, are also described.

    摘要： A bucket handle retainer with a substantially flat rectilinear resilient plate. The plate has an upper tip that corresponds to the inside dimension of the internal cavity of the handle holding portion of a standard five gallon bucket. The plate includes a spring biased finger capable of frictionally engaging the inside wall of the handle holding portion. The plate also includes a holding portion capable of being grasped by a user's fingers to insert or remove the plate from the handle holding portion of the bucket. A preferred embodiment includes the handle retainer is injection molded from nylon plastic.
