    摘要: A machine (200) for winding a strip of material (212) into a helical pipe wherein adjacent convolutions of the strip (212) are interlocked. The machine comprises: a frame (220) having circumferentially spaced supports in the form of rollers (266, 276, 278, 286, 288, 296 and 298) adapted to bear against the inner periphery of the pipe being wound, the outer peripheral surfaces of the rollers forming a helical path for the strip (212) and along which the strip (212) is directed when the machine (200) is in use; driving rollers (224) mounted to the frame (220) for driving the strip (212) around the outside of the rollers so as to follow the helical path and cause the adjacent edges the strip (212) to interlock; and drive means (226) mounted to the frame for driving the driving rollers (224). The driving rollers (224) and the drive means are located wholly inside of the path formed by the rollers and no part of the machine (200) engages the outer periphery of the pipe being wound.

    摘要: A composition for simultaneous cleaning and decontaminating a device. The composition is a per-compound oxidant in an amount effective for decontaminating the device and an enzyme in an amount effective for cleaning the device. The device may be a medical device such as an endoscope or kidney dialyzer and a plurality of devices can be cleaned using the same composition. The composition may additionally contain a corrosion inhibitor in an amount effective to prevent corrosion of a metal, a chelator, a buffer, a dye and combinations thereof.

    摘要: In a method and apparatus for maintaining a minimum transmission power level between two communication stations, each station measures the other's received signal quality, and returns an indication of signal quality as part of a regular maintenance burst. Each station adjusts its own transmission power level based on the returned signal quality indication. The signal quality indication is based on the received ratio of bit energy to total noise power spectral density which is calculated from an estimated bit-error-rate.

    摘要: An integral self-contained, key-operated alarm lock, the major portion of the casing for which can be made from two longitudinally slidably tongued-groove interlocking channel extrusions, has an electronic alarm circuit composed of a finger on-off switch, a striker proximity switch, a bolt position switch and a latching switch which holds the alarm on when it has been activated, until properly shut off.
