Patent CA-2201272-A1 (CA)
Title: Method for collecting fibers from a rotary fiberizer
Inventor: LOFTUS JAMES EDWARD
IPC: D04H3/02
Filed: 1997-03-27
Abstract: A method of producing a fibrous product is disclosed. Molten material is introduced into a rotating spinner (12) which includes a peripheral wall having a plurality of orifices. The molten material is centrifuged through the orifices to create fibers (20). The fibers are directed generally downwardly and away from the spinner. The fibers are intercepted on a collector so that the fibers are draped over the collector. The fibers form first and second suspended portions (52,54) which are oriented generally vertically. The collector and intercepted fibers are moved away from the spinner. The first and second portions of the suspended fibers are raised to a generally horizontal orientation, thereby producing a generally planar fibrous product (28).

IPC: B65D33/34
Filed: 1997-05-07
Abstract: A peel seal zipper tape for reclosable plastic bags  or  packages  includes  a  first  and  a  second mutually interlocking zipper profile disposed on a top surface of a laminated film strip.  The top surface is formed  by  a  layer  of  a  sealant  material.    The laminated film strip also has a bottom surface formed by a layer of a non-peel-seal material.  In use, the laminated film strip  is  folded over enabling  the zipper profiles to be interlocked with one another. In so doing,  portions of  the  top surface of  the laminated film strip face one another, so that they may be joined with a heat seal.  The outside of the folded peel seal zipper tape,  that is,  the bottom surface  of  non-peel-seal  material,  is  bonded  to plastic sheet material from which reclosable plastic bags or packages are made.  In the production of the bags or packages, the mutually facing portions of the laminated  film  strip  are  sealed  together.   The resulting seal gives a visual indication of having been broken when initially opened.
Patent CA-2204794-A1 (CA)
Inventor: STAEHELIN ROLF
IPC: G01T1/00
Filed: 1997-05-08
Abstract: The present invention provides electrode assemblies for LIC imagers that maximize ion collection and the electric field for the minimum bias voltage. To achieve this optimization the ion collection is confined to small regions. Due to this limited ion collection region, high neutralization efficiencies and fast sweep-out times can be obtained. Furthermore, with an electrode separation of approximately 0.1 millimeters, pulse voltages of less than 100 volts can be used. Low voltages result in improved reliability, longer system life, and lower safety risks.

Patent CA-2221217-A1 (CA)
Title: Recursive filters for polyphase structures
Inventor: ALLPRESS STEPHEN ALAN
IPC: H03H17/02
Filed: 1997-11-17
Abstract: Polyphase channelizing transmitters convert multiple signal channels into a single stream for transmission and corresponding polyphase channelizing receivers process the received stream to recover signals corresponding to the original signal channels. The filter transfer functions for both the transmitters and receivers are designed to have non-recursive numerators and recursive denominators. Such filters can be realized using non-recursive (e.g., finite impulse response (FIR)) filters and recursive (e.g., infinite impulse response) filters on opposite sides of a Fourier transform. For a given application, polyphase structures of the present invention may require fewer coefficients to implement than conventional (e.g., FIR-based) solutions and will therefore be less complex and less expensive.

Patent CA-2233729-A1 (CA)
Inventor: FISHMAN SAUL DANIEL
IPC: H04Q3/66
Filed: 1998-03-31
Abstract: The routing of calls in a telecommunications switching system (12 1, 12 2) comprised of one or more fabrics (22 1, 22 2, 22 3) controlled by corresponding fabric controllers (26 1, 262 and 26 3, respectively) is carried out by a routing processor (28) independent of the fabrics. The routing processor actually selects the route for each call by specifying a channel to a neighboring switching system to carry the call. Further, the routing processor has the capability to respond to queries from other switching systems regarding trunk group status and traffic load to enable the processor to assist the routing processor of the other switching system to make routing decisions. By implementing fabric independent routing, routing processing is re-used for new fabric capacity, and is readily extended to accommodate new service types, such as bursty data services.Fabric independent routing achieves lower development cost by avoiding redevelopment of routing functions on new fabric controllers, as they are added, and the addition of new routing features is made on a single routing processor function versus multiple fabric controllers. Fabric independent routing allows routing processing to be implemented on processors with essentially unlimited real-time and memory resources by riding the processor technology curve, and achieves performance advantages such as reduced call set up delay and improved overall switch reliability.

Inventor: KITAMURA ATSUSHI
IPC: E01F9/619
Filed: 1996-12-18
Abstract: A method for hydrophilifying the surface of a substrate by taking advantage of photocatalytic action.      The substrate has a photocatalytic titanic coating (10).      The surface of the photocatalytic coating (10) bears the solid acid that increases a hydrogen bond component (.gamma.s h) in the surface energy in the solid/gas interface of the coating. Photoexcitation of the photocatalyst enhances the hydrogen bond component (.gamma.s h) in the surface energy of the photocatalytic coating (10), accelerating the physical adsorption of molecules of water in the atmosphere through a hydrogen bond (16) onto hydrogen atoms in a terminal OH group (12), bonded to a titanium atom, and a bridge OH group (14) on the surface of the coating. This results in the formation of a high density, physically adsorbed water layer (18) on the surface of the photocatalytic coating (10), thus permitting the surface of the substrate to be easily hydrophilified. The method is applicable to antifogging, antifouling, selfcleaning and cleaning of articles.
Patent CA-2241201-A1 (CA)
Inventor: MENNIE ROBERT BRUCE
IPC: B60S5/00
Filed: 1998-06-19
Abstract: An air brake adjustment tool is described. The air brake adjustment tool is used in almost every step of a pre-trip check or inspection of an air brake system and for any subsequent adjustment of the air brake settings. The air brake adjustment tool comprises a shaft having a first end and a second end. The first end is arranged to have a substantially "T"-like shape. As a result of this arrangement, the first end of the air brake adjustment tool is used as a handle and as a general use hammer. Specifically, the first end is used to check tire inflation and wheel tightness by tapping the lug nuts or lug nut spacer. The second end of the air brake adjustment tool comprises a claw member and a plurality of sockets. The claw member extends laterally from the shaft and comprises a base and two arms. The claw member is used, for example, to adjust the positioning of the brake pads. The plurality of sockets comprise a rear socket, two side sockets and a tip socket. The sockets are used to adjust the slack adjusters so that the brake travel is of the desired length. Thus, the air brake adjustment tool provides a quick and easy method for checking and adjusting air brake systems. Obviously, frequent inspection of air brake settings dramatically decreases the likelihood of air brake failure.
