Patent CA-2136223-A1 (CA)
Title: Joining bodies of thermoplastic material
Inventor: GREIG JOHN MARTYN
IPC: B29C63/14
Filed: 1994-03-31
Abstract: A pipe (10) of polyethylene is reinforced by two layers (12, 14) of polyethylene tape wound around the pipe in opposite directions under tension. The pipe contains carbon black and the layers are unpigmented and free from fillers and are transparent to infra-red radiation to which the first major surface (21) is exposed.  The radiation is in the near infra-red region and has a substantial part of the radiant energy of a wavelength of less than 2.5 micrometers. Very little radiation is absorbed by the layers but a very high absorption occurs in the outer surface of the pipe. This causes the interface between the second major surface (36) of the layer (12) and the first major surface (38) of the pipe and between the second major surface (28) of the layer (14) and the first major surface (30) of the layer (12) to reach temperatures at which fusion welding in the layers welds them together and welds the layer (12) and the pipe (10) together.

Title: Self-Expandable Stent and Stent-Graft and Method of Using Them
Inventor: LAU LILIP
IPC: A61F2/07
Filed: 1995-04-03
Abstract: The device is a foldable stent (122) or stent-graft (370) which may be delivered with (or on) a catheter or via surgical or other suitable techniques. The device is then expanded or unfolded. The expandable stent structure preferably utilizes at least one torsional member (100) generally aligned with the longitudinal axis of the stent (122). The stent (122) preferably has an undulating shape. It may be helically deployed to form the generally cylindrical shape eventually deployed as the stent (122) or it may be formed of one or more rings (302). The structure desirably is aligned to allow those undulating shapes in adjacent rings (322) or turns of the helix to be in phase. The adjacent undulating shapes may be held in that phased relationship using a flexible linkage often made of a polymeric material. The stent (122) is self-expanding, kink-resistant, easily bent along its longitudinal axis, does not change its length during that expansion, and is able to provide collapsible support for otherwise frangible graft material. The graft component (134) cooperating with the stent (122) is tubular and may be biocompatible polymeric or collagenous material or combinations of the two which may, if desired, be reinforced with fibers. <IMAGE>

Title: Apparatus and methods for measuring and detecting variations in the value of a capacitor
Inventor: HUGHEY BRADLEY WARD
IPC: G01R27/26
Filed: 1994-03-14
Abstract: A method measures the value of a capacitor and detects small variations in the value of a capacitor around a reference value. The capacitance of the capacitor may be determined by applying a voltage input having a known amplitude and wave form, V, to an RC circuit having a substantially known or constant load impedance, R, and sampling the voltage across the resistor (6 or 16) or capacitor (8 or 14) at a precisely controlled elapsed time interval, T. The method permits detector circuits to be created for measuring small variations in value with precision and accuracy. Solid state keypads (30) incorporating sensor cells (32) and software algorithms provide human interface systems which are not subject to environmentally induced errors or errors due to component aging.

Patent CA-2165703-A1 (CA)
Inventor: KAMIJO NORIYUKI
IPC: B65H41/00
Filed: 1995-12-20
Abstract: This invention provides a separation method for an adhesive tape and a separation device that can reliably and efficiently perform the operation of removing the backing sheet from the adhesive sheet of the adhesive tape and can be automated with a simple structure. The adhesive tape comprises a base sheet, an adhesive sheet which is applied to the base sheet and a backing sheet laminated to the base sheet. According to the invention, one end of the adhesive tape is supported leaving that end as a free end. Separation means is used to bend the free end in the direction from a first surface of the adhesive tape to a second surface of the adhesive tape until slippage occurs between the adhesive sheet and backing sheet. While in this state, the separation means is withdrawn from the adhesive tape as it traces the end surface at the free end. Thus, the backing sheet is removed from the adhesive tape and can be affixed to an object.

Title: High profile geotextile fabrics
Inventor: THEISEN MARC S
IPC: E02D17/20
Filed: 1994-09-15
Abstract: A method for stabilizing soil and reinforcing vegetation includes placing a single-layered, three-dimensional, high-profile woven geotextile fabric (10) into the soil. The single-layered, homogeneous fabric (10) is woven from monofilament yarns (12, 14) having different heat shrinkage characteristics such that, when heated, the fabric forms a thick three-dimensional, cuspated profile. The monofilament yarns (12, 14) have a relatively high tensile strength an a relatively high modulus at 10 percent elongation so as to provide a fabric which is greater in strength and more dimensionally stable than other geotextile structures. Thus, the geotextile fabric (10) is suitable for use on slopes, ditches and other embankments and surfaces where erosion control, soil stabilization and or vegetative reinforcement may be necessary. The homogeneous, single-component nature of the fabric (10) promotes easier handling and minimizes failure points, while offering a thick, strong and dimensionally stable product upon installation.
