Abstract: A cleaning method and apparatus that provides lubrication to a secondary detoning roll in a cleaner brush system, thus reducing cleaning failures. The toner particles removed from the first detoning roll are transported to the second detoning roll. This allows lubrication of the second detoning roll and reduces the wear problem of the second detoning roll due to lack of lubrication.

Abstract: An ultra small diameter reinforced catheter or the like type of tubular product is produced by winding reinforcing strands (20) on the surface of a plastic tube (22) and introducing the same into a heated die (16) which compresses the strands (20) against the tubing (22) and at the same time heats and softens superficial portions of the tubing wall with both conductive and radiant heat. This allows the strands to sink into the tubing wall. Following this, the compression and the conductive heating are removed while the tubing continues to be exposed to radiant heat from the die. During this last stage (III), the tension in the strands induces the strands to assume a predetermined position between the inner and outer surfaces of the tubing.

Abstract: A discontinuous ring is formed by separate bidirectional optical communication links, with possibly different transmission speeds, synchronous or asynchronous transmission, and ratios of working to protection channels, each linking a pair of terminals in different nodes of a communication system. To protect protection-switched traffic on a communication link from a link failure, it is routed around the ring via the protection channel of the other communication links. To this end, an optical switch is provided between the protection channel of each link and the associated terminals in each node, and is controlled differently in nodes adjacent the link failure and in nodes not adjacent the link failure to route the protection-switched traffic accordingly. Rapid protection switching is facilitated by controlling the optical switches using wavelength detectors directionally coupled to the protection channel at each node.

Abstract: Iodine-125 is produced by neutron irradiation of 124Xe gas to form 125Xe and  permitting decay of 125Xe to form 125I. Irradiation of the xenon-124 is effected in a first chamber within an enclosure and decay is effected in a second chamber within the enclosure and free from neutron flux. The apparatu s is submersible in a nuclear reactor pool so as to absorb any radiation escaping the apparatus during the process. Xenon can be caused to move betwe en the chambers remotely, underwater. The second chamber is removable from said  enclosure and is transported to a suitable location to recover the 125I from  its interior. Such recovery is effected by admitting an aqueous wash solutio n into the second chamber, whereupon it is heated, causing water from the wash  solution to reflux and cleanse the interior surfaces of the second chamber, thus creating an aqueous solution of 125I, which then is caused to drain int o a suitable container.

Granted: 2005-09-20
Abstract: A quick connect coupling (20) generally comprising a housing (22) having an axial bore extending inwardly from an entrance and increasing in diameter moving into the housing (22). A tube (24) has a tube bead (26) of increased diameter spaced from an inner end (30) of the tube (24) and is insertable into the bore. A generally annular radial ly expandable collet (64) disposed within the bore expands upon insertion of the tube (24) and contracts onto the tube (24) outwardly of the tube bead (26). The collet (64) functions as a wedge between the tube bead (26) and the increasing diameter portion of the housing (22), thereby retaining the tube (24) within the housing (22). In one embodiment, a spring (74 or 142) disposed within the housing (22) biases the collet (64) toward the entrance of the housing, ensuring proper position of the collet (64) in extreme conditions. The inventive coll et (64) allows smaller tube bead (26) diameters to be used.

Abstract: A phase locked loop circuit includes a phase comparator, a temperature information output section, an arithmetic processing circuit, and a voltage controlled oscillator.  The phase comparator compares the phase of an input signal with that of a frequency division signal obtained by frequency-dividing an output frequency signal.  The frequency division signal has the same frequency as that of the input signal.  The temperature information output section outputs temperature information based on an ambient temperature.  The arithmetic processing circuit performs arithmetic processing by using the temperature information from the temperature information output section and an output from the phase comparator, and outputs the arithmetic processing result as a voltage control signal.          The voltage controlled oscillator outputs an output frequency signal in accordance with the voltage control signal from the arithmetic processing section.
