Patent CA-2298078-A1 (CA)
Inventor: BACON JOHN ELLIS
IPC: B31F1/00
Filed: 2000-02-02
Abstract: An apparatus is provided for forming an outwardly-rolled lip on an open end of a deformable cylindrical container body. The apparatus may include a mandrel having a generally cylindrical-shaped portion for movably supporting at least a portion of an interior surface of the container body. The apparatus further includes a lipforming die assembly forming a part of the mandrel and having an annular cavity defining an open mouth portion and a closed bottom portion which defines a surface area extending generally radially outwardly of the mandrel outer surface and which is oriented with the open mouth portion generally transverse to an outer periphery of the container body and which faces the open end of the container body around the periphery. An axial forcing member contacts the other end of the container body for axially moving the container body along the outer surface of the mandrel and the container open end into and through the die assembly. The cavity bottom portion surface area of the lip-forming die assembly has a generally C-shaped cross-sectional contour in the direction of its outward extension which includes a combination of curved and straight sections positioned at predetermined radii and angles to a longitudinal axis of the container body, so that, when the outer periphery of the open end of the container body is forced into and through the die assembly to form the outwardly-rolled lip, the end of the container body will contact only a part of the bottom portion surface area of the die cavity to reduce frictional engagement and to minimize the force necessary to move the end of the container body through the die.

Title: Nanometric structures
Inventor: SPATZ JOACHIM
IPC: B82B3/00
Filed: 1998-10-29
Abstract: The invention relates to nanometric structuring and decorating of substrates.  The invention especially relates to surface decorated substrates on which ordered nanometric surface structures are deposited, said structures being comprised of metal and/or metal oxide clusters and/or semiconductor clusters.  The invention also relates to a method for producing and applying said surface decorated structures in order to epoxidize C3-C8-alkenes or to oxidize CO to CO2, and relates to surface structured substrates, especially Pt, Au, GaAs, InyGaAs, AlxGaAs, Si, SiO2, Ge, SixNy, SixGaAs, InP, InPSi, GaInAsP, glass, graphite, diamond, mica, SrTiO3 or the doped modifications thereof, which are nanometrically structured over macroscopic areas. In addition, the invention relates to a method for the production of said surface structured substrates.  The invention is based on the film formation of core shell polymer systems whose core areas are selectively modified or charged with corresponding metal compounds in a solution and construct the structures which are orderly arranged in the thin films. These films which are deposited on the substrate surfaces are selectively etched in such a way that the organic polymer components are completely removed and, as a result, the substrate is decorated in an orderly arrangement by the inorganic residues. The structured films can further serve as masks which make it possible to selectively etch the substrate and to transfer such a structure, said structure given by the film, to the substrate.

Filed: 1999-11-12
Abstract: The present invention is a method for maximizing water removal from an absorbent web in a press nip, thus improving the efficiency of a papermaking machine. The present invention uses a pressing unit having a blanket with a void volume and with a pressure profile that maximizes water removal in the press section or on the Yankee dryer of a paper machine. The pressure profile of the pressing unit according to the present invention has a very steep pressure drop at and/or following the exit of a pressure distribution curve in order to maximize water removal by minimizing rewet of the web.  The improved pressure profile according to the present invention results in increased water removal and/or improved line speed, thus improving efficiency. The configuration and low void volume of the pressing unit blank may further increase water removal and/or improve line speed, which also improves efficiency.

Title: Method for authorising a communication between at least two devices, as well as telecommunication system, as well as device
Inventor: DANIEL PATRICK
IPC: H04M1/724
Filed: 2000-09-25
Abstract: Known telecommunication systems like a DECT-system comprising a base-station and a handset or like a Digital Home Network system comprising a controller and several devices or a car radio system comprising a car radio and a front are based upon an authorisation process for introducing a new device or for coupling an already introduced but decoupled old device to said telecommunication system. Such authorisation process, which often is user-unfriendly, can be partially or even completely avoided by either using the result of an old identification process or by using a new identification process for identifying a user, which can be done in a much more user-friendly way.

Patent CA-2324719-A1 (CA)
Title: Thermally actuated microelectromechanical systems including thermal isolation structures
Inventor: MAHADEVAN RAMASWAMY
IPC: H01H1/00
Filed: 2000-10-27
Abstract: Microelectromechanical structures include a microelectronic substrate and spaced apart supports on the microelectronic substrate. A beam extends between the spaced apart supports and expands upon application of heat thereto, to thereby cause displacement of the beam between the spaced apart supports. The application of heat to the beam creates a thermal conduction path from the beam through the spaced apart supports and into the substrate. A thermal isolation structure in the heat conduction path reduces thermal conduction from the beam, through the spaced apart supports and into the substrate, compared to absence of the thermal isolation structure. The thermal isolation structure preferably has lower thermal conductivity than the beam and the supports. The heat that remains in the beam thereby can be increased. The thermal isolation structure may include a thermally insulating structure at each end of the beam, a thermally insulating structure in each spaced apart support, a thermally insulating structure in the substrate adjacent each spaced apart support, and/or at least one thermally insulating structure in the beam. Accordingly, improved thermal efficiency for microelectromechanical structures may be provided, to thereby allow lower power, higher deflection, larger force and/or higher speed.
