Patent CA-2098212-A1 (CA)
Inventor: ARROYO CANDIDO J
IPC: G02B6/44
Filed: 1993-06-11
Abstract: An optical fiber cable (20) includes provisions in a core thereof for preventing the flow of water longitudinally along the care and for preventing freezing of such water. The provisions for preventing freezing of water within the core, which could effect adversely the optical fibers, includes an antifreeze material. Each of two tapes may be impregnated with an antifreeze material such as propylene glycol, for example, and used to provide a laminate with a superabsorbent powder therebetween.      Advantageously, the cable may have suitable flame retardance so that it may extend from an outside manhole to distribution paints within a building.

Patent CA-2107047-A1 (CA)
Inventor: BENTLEY ALAN M
IPC: G06F13/00
Filed: 1993-09-27
Abstract: The invention relates to a wide area network (31) implemented on a circuit-switched public data network (10). Terminals (34, 36, 38, 40) have access to a plurality of data channels (B - channels) and a control channel (D - channel) into the network using a balanced protocol. The invention provides a method for reducing connect time between the terminals over the data channels. To do this a conversation is established between a transaction program on the local terminal and a transaction program on the remote terminal. Responsive to generation of a frame for transmission by the transaction program on the local terminal to the transaction program on the remote terminal, a channel connection between the local terminal and a remote terminal including a data channel connecting each terminal into the wide area network is established if no channel connection already exists. Responsive to expiration of a predetermined period after last transmission or receipt of a frame and existence of the channel connection for a minimum connect period, the channel connection is disestablished without interrupting the conversation between the transaction programs. The predetermined period and the minimum connect period are optimized to minimize costs under a tariff structure for the circuit-switched public data network. <IMAGE>

Title: Fusion protein from feline leukaemia virus gp70 as vaccine
Inventor: SPIBEY NORMAN
IPC: C07K19/00
Filed: 1993-05-14
Abstract: A vaccine against feline leukaemia virus (FeLV) comprises a protein formed of two proteins derived from FeLV gp70 which are not adjacent in the native protein, particularly VR1 and VR5 or effective fragments thereof. VR5 is preferably attached to the carboxy terminus of VR1.

Title: In-line cord ground fault circuit interrupter
Inventor: GERNHARDT PAUL
IPC: H01H9/04
Filed: 1994-02-14
Abstract: An in-line cord ground fault circuit interrupter has a tripping relay whose various components are an integral part of the GFCI housing, instead of being self-contained. The front cover of the housing has the necessary bosses, guide slots, and screw holes for mounting of all the mechanical and electrical elements of the relay. The rear cover serves as a water resistant enclosure and holds the relay elements in position across the width of the housing.      The relay's movable contact arms are attached directly to the printed circuit board of the GFCI. The relay armature is located by ribs on the front cover and is trapped in position when the relay coil and frame assembly is pushed over it using guide slots in the front cover. The armature has integral arms extending to each side wherein each arm has an actuating cam on its end.      Gripping ribs and strain relief ribs are placed at the cord entrances to the housing with a chamber formed therebetween. The cord grips support the cords while the strain relief prevents Forces applied to the cords outside of the enclosure being applied to the joints within the enclosure while a sealant placed in the chambers provides an environmental seal.

Patent CA-2120805-A1 (CA)
Title: Faulted circuit indicator
Inventor: BANTING JOHN F
IPC: G01R15/18
Filed: 1994-04-07
Abstract: A faulted circuit indicator with a high visibility spherical display device is disclosed for indicating a fault condition.     Disposed within the display apparatus is a permanent magnet 42 that is in magnetic communication with, and actuated by, an electromagnet. The permanent magnet is rotatably mounted within the display and is attached to a spherical flag. The spherical flag has two different colors at its hemisphere to represent fault and no-fault conditions. The electromagnet comprises a magnetic core and coil assembly and is magnetized by a current pulse received from the indicator circuitry. By changing the direction of the current through the coil assembly, the polarity of the electromagnet is reversed, which in turn causes the permanent magnet to rotate 180° to realign with the poles of the electromagnet. Because the flag is colored about its hemisphere, the rotation of the permanent magnet results in a change of color being displayed in the display device.

Inventor: WOOLLEY EDWARD G
IPC: B25B15/02
Filed: 1994-04-22
Abstract: 1.   The present invention relates to tightening or removing screws of many sizes and shapes, eg. slit, square, star, hexagon, octagon, pentagon etc.  from a 1.5 mm slit to 15mm slit of a screw head of said shapes and sizes.  Also it will tighten or loosen nuts limited to size and depth of screw neck, plus bolt, again limited to the size of screw driver tip, which are 271 x .5mm metal steel hexagon pins which travel up the inner casing to a hexagon comb mounted near the top of drivers inner housing.  At this comb each of the 271 pins has its own hexagon pocket, that of the natural shape of a honey comb.  Each metal steel pin has a mounting spring, which is first mounted into the inside top of each hexagon hole, Fig.1.  The spring action allows each pin to move up and down to allow only the right amount of pins to fill the slits of screw or surround the outer side portions of either bolt or nut.  Excess pins retract into hexagon comb. Fig. 1, 9.

Abstract: The composite material of the invention is constituted by a thermoplastic film (2) having a multiplicity of perforation craters (4) of small dimensions on one of its faces and whose smooth, other face is covered in fibers (3) most of which are thermoplastic and that are bonded to one another and to the film (3) in substantially continuous manner.  The material is usable as a breathing film for absorbent hygiene articles, in particular diapers.  A method of manufacture consists: a) in dispersing a sheet of fibers (3) most of which are thermoplastic onto a thermoplastic film (2), or in extruding a thermoplastic film onto a non-woven fabric made of such fibers; b) in presenting the fiber/film composite onto a surface that is provided with orifices; and c) in heating to a temperature close to the softening temperature of the two thermoplastic materials while simultaneously establishing suction through the orifices so as to cause the film overlying said orifices to puncture.  The method may include a prior step of pre-coating with adhesive, which step may be implemented, in particular, by the melt-blown technique at a rate of 0.2 g/m2 to 5 g/m2 of adhesive.
