Patent CA-2352992-A1 (CA)
Inventor: FLEURY PHILIP J
IPC: B65H19/22
Filed: 2001-07-13
Abstract: An apparatus for winding tape includes a cantilevered support arm for supporting in a winding position a core onto which the tape is to be wound with a surface drive roller pivotal to a position engaging the outside of the package for causing rotation of the package in the driving position about a longitudinal axis of the arm. A lay-on roller directs the tape on to the core such that the rotation of the core acts to wind the tape into the package. The lay-on roller is driven by a lead screw in movement longitudinally of the axis to form a generally cylindrical package structure of the tape. With the lay-on roller in a retracted position to one side, the finished package on the support arm is moved by a rotatable drive head rotating about a vertical axis from the winding position away from the drive roller to a doffing position and simultaneously an empty core is moved from the doffing position over the drive roller to the winding position. The apparatus includes four winding positions at the corners of a rectangular frame so that each package at each of the positions is moved simultaneously to the doffing position outside the frame for ready access by an operator.

Inventor: MOORE RONALD S
IPC: G02F1/025
Filed: 2001-11-09
Abstract: An optical device, such as an electro-absorption modulator, has a waveguide formed onto a base. Electrodes adjacent the waveguide are used to selectively apply an electric field to the device in order to control the passage of light through the device. To prevent overheating of the device in a region near the point of optical entry, the electrode, which acts as a thermal conduit to dissipate heat from the waveguide is extended over the region. To prevent undesirable electrical contact between the electrode and the region, the normally electrically conducting contact layer between the electrode and the waveguide is removed in that region and replaced by an isolation dielectric.

Title: Bidirectional multiplexer and demultiplexer based on a single echelle waveguide grating
Inventor: DAVIES MICHAEL
IPC: G02B5/18
Filed: 2001-12-07
Abstract: A bidirectional multiplexer and demultiplexer based on a single waveguide grating is presented. In one embodiment of the invention, the device contains a multi/demultiplexer having an echelle grating disposed between a plurality of input channels and a plurality of output channel arrays. The input and output channels are assigned in a particular order, such that the multiplex and demultiplex functions have the same wavelength channels and such that the blaze angle of the grating facets are optimized simultaneously for both the multiplex and demultiplex function. Because the optical signals are multiplexed and demultiplexed by the same dispersive element, problems of mismatching performance introduced by using different optical components are obviated. The input/output waveguides of the dual-function device can be coupled to a single fiber array, thus reducing the packaging cost.

Title: Split ring for gas turbine casing
Inventor: SUGISHITA HIDEAKI
IPC: F01D9/04
Filed: 2002-01-14
Abstract: A split ring is disposed on an inner wall of a gas turbine casing. The split ring is composed of a plurality of split segments that are arranged on the inner wall of the casing in circumferential direction. A predetermined clearance is formed between the inner face of a split segment and the rotor blade tips. The split segments are arranged so that a predetermined circumferential clearance is formed between the split segments in order to allow the thermal expansion of the segments. A circumferential end face located upstream side of the segments with respect to the direction of the rotor blade rotation is connected to the inner face by a transition face having a surface foamed as an inclined plane. The inclined plane prevents the swirl flow caused by the rotating rotor blade from impinging the upstream end face and, thereby, suppresses a temperature rise of the split segment at the upstream end face.

Title: Improved storage and maintenance of blood products including red blood cells and platelets
Inventor: DOTTORI SECONDO
IPC: A61K35/14
Filed: 2000-06-05
Abstract: Cell membrane maintenance of red blood cells and platelet concentrates is improved by the addition of 1 mM - 10 mM L-carnitine and derivatives. This improvement allows extension of the period of viability of packed red blood cells and platelet concentrations beyond current periods. Additionally, the materials so treated exhibit extended circulation half life upon transfusion  to a patient. Improvements in membrane maintenance achieved by this method permit irradiation of sealed containers of blood products so as to substantially sterilize and destroy leukocytes in the same. The addition of L- carnitine and derivatives also suppresses bacterial growth and reduces glycolysis in whole blood and blood fractions.
