Patent CA-2129573-A1 (CA)
Title: Self-contained biological indicator
Inventor: SMITH DANIEL F
IPC: C12Q1/22
Filed: 1994-08-05
Abstract: A self-contained biological indicator includes an outer container that is translucent and liquid impermeable. The container is normally closed by a vapor-permeable, microorganism-impermeable closure and contains a source of viable microorganisms, a culture medium, a composition that decomposes hydrogen peroxide, and a detector that undergoes a visible change in response to growth of the microorganisms. In operation, the indicator is first subjected to a sterilization cycle in a hydrogen peroxide sterilizer. Without opening the outer container, the microorganism source, culture medium, and hydrogen peroxide-decomposing composition are brought into contact.      The indicator is placed in an incubator, after which the detector responds to any microorganism growth, indicative of incomplete sterilization. But for the hydrogen peroxide-decomposing composition, hydrogen peroxide that becomes bound to the microorganism support during sterilization, could kill the microorganisms afterwards, yielding a false indication of complete sterilization.
Patent CA-2129796-A1 (CA)
Title: Applicator tool for installing flexible coverings
Inventor: MONROE JAMES M
IPC: B44C7/08
Filed: 1994-08-09
Abstract: ABSTRACT    An applicator tool is provided for use in applying flexible coverings, such as vinyl wall coverings, onto a support surface and for smoothing out wrinkles during application. The tool includes an elongated handle portion from which a flat blade portion laterally extends. The blade is formed of a stiff, yet resilient plastic, preferably an ultra-high molecular weight polymer, that is self lubricating and has a low co-efficient of friction. The blade terminates in a longitudinally extending primary working edge that is relatively blunt. Secondary edges extend between the handle portion and each end of the primary working edge. Each secondary edge and the primary working edge forms a rounded corner with the corners formed at different radii of curvature. It is preferred that one secondary edge is at a right angle while the other secondary edge is at an acute angle with respect to the primary working edge. Margins adjacent each edge are tapered by providing one or more faces that are oblique to the blade surfaces. Preferably the tool is of integral one-piece molded construction having pairs of ribs that project oppositely one another to form the handle. Tear-drop shaped flat end panels are oriented perpendicularly to the blade portion to form the tool ends, and elongated opening helps form the handle. Notch and port openings facilitate hanging the tool from a belt clip.

Title: Process for producing cis-3-hydroxy-l-proline
Inventor: OZAKI AKIO
IPC: C12N9/02
Filed: 1994-09-09
Abstract: Provided is a process for industrially producing cis-3-hydroxy-L-proline useful as a raw material for medicines or as an additive to foods. L-proline is converted into cis-3-hydroxy-L-proline in the presence of an enzyme source which is derived from a microorganism belonging to the genus Streptomyces or Bacillus and which catalyzes hydroxylation of L-proline into cis-3-hydroxy-L-proline, a divalent iron ion and 2-ketoglutaric acid, in an aqueous medium, and the produced cis-3-hydroxy-L-proline is recovered from the aqueous medium. Also provided is a novel enzyme L-proline-3-hydroxylase, which is useful for the process.

Patent CA-2145884-A1 (CA)
Title: Split transactions and pipelined arbitration of microprocessors in multiprocessing computer systems
Inventor: TAYLOR MARK
IPC: G06F13/364
Filed: 1993-09-29
Abstract: Three prioritization schemes for determining which of several CPUs receives priority to become bus master of a host bus in a multiprocessor system, and an arbitration scheme for transferring control from one bus master to another.  Each prioritization scheme prioritizes n elements, where a total of (n/2)x(n-1) priority bits monitors the relative priority between each pair of elements.  An element receives the highest priority when each of the n-1 priority bits associated with that element points to it.  In the arbitration scheme, the current bus master of the host bus determines when transfer of control of the host bus occurs as governed by one of the prioritization schemes.  The arbitration scheme gives EISA bus masters, RAM refresh and DMA greater priority than CPUs acting as bus masters, and allows a temporary bus master to interrupt the current bus master to perform a write-back cache intervention cycle.  The arbitration scheme also supports address pipelining, bursting, split transactions and reservations of CPUs aborted when attempting a locked cycle.  Address pipelining allows the next bus master to assert its address and status signals before the beginning of the data transfer phase of the next bus master.  Split transactions allows a CPU posting a read to the EISA bus to arbitrate the host bus to another device without re-arbitrating for the host bus to retrieve the data. The data is asserted on the host bus when it is idle even if the host bus is being controlled by another device.

Patent CA-2151478-A1 (CA)
Title: Pressure clamp for telecommunications closure
Inventor: MCCALL MARK
IPC: G02B6/00
Filed: 1993-12-06
Abstract: A telecommunications closure includes a pressure clamp for sealingly clamping mating parts of the closure together so as to form a water tight seal.  The clamp member requires no tools during installation and creates no uncertainty as to the generation of appropriate clamp pressure on a sealing 0-ring when installed.  The pressure clamp includes an over-center latch which is rotatable between a first unlatched position and a second latched position, a clamping pressure generated by the latch increasing to a maximum value as the rotatable latch is moved from its first position to an intermediate position between the first and second positions and then decreases from this maximum value as the latch is moved from the intermediate position to the second position so as to generate a predetermined appropriate clamping pressure when in its second position so as to appropriately compress the O-ring disposed within a groove between the closure parts at their mating area.

Title: Fiber optic cable system including main and drop cables and associated fabrication method
Inventor: RAY CRAIG DWAYNE
IPC: G02B6/24
Filed: 1994-04-15
Abstract: A fiber optic cable system, such as a preterminated fiber cable, includes a main cable and one or more drop cables connected to the main cable at spaced apart locations along the main cable. The drop cable is spliced to the main cable using a splice closure including a fiber guide that secures spliced together end portions of the respective fibers in a longitudinally extending direction so that they are devoid of any slack coils of optical fibers. Accordingly the overall diameter of the splice closure is relatively small thereby permitting the cable system to be stored on a reel and to be readily placed within small diameter conduits. The splice closure includes a heat recoverable housing surrounding the fiber guide. Cable sheath end portions are scaled by melting C-shaped bodies of heat flowable material positioned adjacent cable sheath end portions.
