Title: Exchange accessory for use with a monorail catheter
Inventor: DUANE PATRICK J
IPC: A61M25/06
Filed: 1995-12-22
Abstract: An exchange accessory useful with monorail and other types of catheters has a hollow, elongated sleeve for insertion into a Tuohy-Borst connector or the like, and an enlarged head at its proximal end to restrain the sleeve from advancing with the catheter into the connector. The sleeve is slidably mounted on the catheter shaft so that it may be interposed between a sealing member within the connector and the catheter. The internal diameter of the sleeve is greater than and complementary with the external diameter of the catheter shaft to define a space about the catheter shaft sufficient to allow backbleed of blood therethrough in a controlled manner. In one embodiment, the sleeve has a slotted head to accommodate a guidewire which may extend in parallel to the catheter shaft, for example, when used with a monorail type catheter. The slot permits the guidewire to extend proximal to the connector without bending or kinking. In another embodiment, the exchange accessory may be assembled onto a conventional catheter shaft. As a modificationto these embodiments, an aperture may be provided for selectively engaging the catheter by closing the connector on the sleeve with the aperture aligned with asealing member of the connector.

Title: Child resistant closure assembly
Inventor: LOADER JOHN
IPC: B65D50/06
Filed: 1996-02-12
Abstract: The closure assembly of Figures 1 and 3 comprises a container 1, a cap 2 having a skirt portion 3, and a captive band 4 attached via a tamper-evident tear-off band 5 and a pair of frangible connections 6 and 7 to the skirt portion 3.  Arrows 8 on the skirt 3 and 9 on the container 1 show that the cap 2 has been put on in the aligned position.  A tab 10 on one end of the tear-off band 5 provides a grip for the fingers in removing the band. In Figure 3 the tab 10 has been torn away to reveal a detent means on the container neck in the form of a projection 11. This is partly situated in a gap under the tab 10 before this has been lifted away, and partly under the start end of the tear-off band 5, which is adapted to flex slightly to accommodate the projection 11 without any significant damage to the frangible connections 6 and 7.   If an attempt is made to remove the cap 2 in the aligned position, before the frangible connections 6 and 7 have been torn, the lower surface 11a of the projection will be brought into abutment with an upwardly directed surface 4a of captive band 4, which constitutes a detent means on the captive band, so resisting removal of the cap.

Title: Thread loosening device
Inventor: SMITH JAMES
IPC: B25B27/02
Filed: 1996-02-29
Abstract: A thread loosening device adaptable to a pair of pipe wrenches or the like that comprises a threaded rod in threaded engagement to a first housing and a second housing, thehousings being axially moveable along the longitudinal axis of the threaded rod. The threaded rod has a plurality of individual threads with the same diameter and pitch as the threads in the housings. Anchor members are affixed to the housings for pivotally securing the handles of the pipe wrenches. End caps are affixed to the opposite ends of the threaded rod, the end caps having a hexagon surface for co-operation with a mechanical wrench or socket. The rotation of the end caps forces the housings to move in opposite directions along the threaded rod thereby creating an opposing movement of the wrench handles and subsequent wrench jaw movements relative to each other. The clockwise and counter-clockwise rotation of the wrench jaws provides the torque to loosen tight threads and thread couplings.
Patent CA-2171189-A1 (CA)
Title: Emission quenching sensors
Inventor: BENTSEN JAMES G
IPC: G01N21/64
Filed: 1994-08-18
Abstract: The present invention relates to a sensing instrument and method for measuring the concentration of an analyte. The sensing instrument includes a sensing element including at least a first emissive indicator characterized by a bimolecular quenching rate constant kq, one or more fluorescence lifetimes o above a lowest lifetime oL, and capable of emitting analyte concentration dependent signals when exposed to an excitation signal in the presence of quencher. An excitation system coupled to the sensing element provides an amplitude modulated excitation signal at one or more radial modulation frequencies .omega.. A detector coupled to the sensing element detects the analyte concentration dependent signals and provides detected signals. A processor, preferably including memory for storing information characterizing a calibration relationship between analyte concentration and the concentration dependent parameter is coupled to the detector. The processor univariantly processes the detected signals and provides output signals representative of analyte concentration. The sensing element and/or excitation system are configured to enable the instrument to operate sufficiently within the condition ¢(kq¢Q!)2+.omega.2!o2 >> 1+2kqo¢Q! such that a slope of the relationship between the concentration dependent parameter and anlayte concentration is independent of o variability and/or heterogeneity for all analyte concentrations within the operating range and for all lifetimes o greater than oL. When configured in this manner the calibration slope is independent of o variability and/or heterogeneity. The sensor can therefore be recalibrated by modifying the stored calibration information characterizing the intercept, but not the slope, of the relationship in response to sensing element exposure to one calibration analyte of a known concentration.

Abstract: A method and an apparatus for closing the tool of a plastics-processing machine, especially a blow-molding machine, concerns a two-part tool (1, 2) which is supported by two tool mounting plates (3, 4), at least one run drive (5), at least two closure drives (8), and such that the closure drives (8) each have a hydraulic piston-cylinder system with a cylinder (9), a piston (10), and a cylinder rod (11), and such that an inflow (14) and an outflow (15) for hydraulic oil is situated at the cylinder (9). Also, the end of the piston rod (11) has an interlock element (12) which interacts with a counter-piece (13), such that the piston rod (11) does not interlock with the closure piece (13), in order to apply the closure force, until the tool (1, 2) is situated near its closed position. According to the invention, all the closure drives (8) for closing the tool (1, 2) with a high force are actuated by a common control or regulation mechanism; no synchronization devices between the individual closure drives 8 are present. The entire closure motion of the tool (1, 2) takes place continuously and without interruption of the closure process. In this way, a more economical mode of operation is achieved by a simpler and more economical design.

Title: Method and apparatus for matching compressed video signals to a communications channel
Inventor: KALMANEK CHARLES ROBERT JR
IPC: H04N7/26
Filed: 1996-04-11
Abstract: A method and apparatus for matching compressed video signals to a communications channel. The compressed bitstream is partially decompressed and the bitstream is regenerated with a reduced bit rate to match the channel capacity. Specifically, control information is decoded and entropy decoding is performed on the entropy coded, quantized frequency domain data. Then, the quantized frequency domain data is re-quantized and re-entropy coded so that the resulting compressed bitstream does not exceed the channel capacity bit rate. However, this entire rate conversion process is performed without converting the frequency domain data out of the frequency domain (and back again) as is done by prior art techniques. That is, the frequency domain data is not inverse transformed (out of the frequency domain) in the process of re-quantization. In this manner, a compressed and stored video signal can be matched to the constraints of a given communications channel with substantially less computational cost than is required by the techniques of the prior art.
