    摘要： A lung exercise apparatus and method with an enclosure, with an inside, an outside and an open top, configured to hold a liquid of a first density. An additive to the liquid that increases the first density such that a person in the liquid is more buoyant. Weight removably connectable with the person such that a person in the enclosure is held vertical in the enclosure and partially immersed in the liquid below a surface of the liquid and with some of a person's body above the surface of the liquid. And a harness that is removably connectable with the person to hold some of the person's body above the surface of the liquid where lungs in a person's body are below the surface of the liquid.

    摘要： An optically variable device and method of manufacturing the device is disclosed, the device including a plurality of zero-order diffraction grating elements some of which are modulated such that a coloured at least partially polarized image is visible to a person viewing the device, observing a first optically variable effect when the device is rotated about an axis substantially perpendicular to the plane, and a second optically variable effect when the device is viewed under polarized light and rotated about an axis substantially perpendicular to or parallel with the plane. The device is particularly suitable for security documents such as bank notes. Preferably, the first optically variable effect is produced by a change in brightness and/or color of the grating elements and the second optically variable effect may likewise be produced by a change in brightness and/or color of the grating elements. The device advantageously provides two different types of optically variable effect may be provided in a single device. This is possible due to the use of zero-order grating elements as the “pixels” of the colored image. Each pixel, under illumination by unpolarized light, produces reflected light of a defined color which is also at least partially polarized.

    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.

    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： An apparatus for producing a yarn including reciprocating twisting stage (4) adapted to simultaneously twist one or more slivers to produce one or more twisted strands, including one or more rollers (6a, 6b) arranged to move reciprocally (B) along the axis of rotation of the roller(s) to input twist to the sliver(s), and control means enabling control and variation of one or more of: (a) rotation speed of the rollers(s); (b) extent of transverse movement of the roller(s)s; or (c) speed of the transverse movement of the roller(s), to vary the twist imparted to the sliver(s) or strand(s).
