Patent CA-2102010-C (CA)
Inventor: SKINNER ANDREW C
IPC: B22D41/005
Filed: 1993-10-29
Granted: 2002-03-05
Abstract: A low-flexure molten metal distribution launder comprises an elongated structural beam which extends over a plurality of casting stations. A  plurality of metal level sensors extend downward from the elongated structural beam to measure molten metal levels in underlying metal casting stations. A plurality of spaced U-shaped refractory hangers are supported within the structural beam to form a refractory channel. Refractory liners are received within the refractory hangers to form a molten metal trough within the structural beam. The hangers are spaced from each other and supported from the structural beam in such a way as to allow them to expand and contract relative to the structural beam without subjecting the structural beam to expansion and contraction. The walls of the refractory hangers are air-cooled to reduce heat transfer from the refractory hangers to the structural beam.

Title: Spinal fluid driven artificial organ
Inventor: OMMAYA AYUB K
IPC: A61F2/02
Filed: 1992-02-07
Granted: 1996-01-30
Abstract: The present invention concerns a spinal fluid driven artificial organ device and methods for its use. The device (10) has a tripartite chamber with three sections. A micropore filter (B) separates chamber section (I) from chamber section (2) and a micro-pore filter (c) separates chamber section (2) from chamber section (3). CSF enters chamber section (I) via an inlet tube (T1) and an one way valve (V1). Micropore filter (B) allows entry of CSF into chamber section (2) but does not allow exit of any cells from chamber section (2) into chamber section (1). Micropore filter (c) allows free passage of CSF from chamber section (2) into cham-ber section (3) and prevents any cells in chamber section (2) from entering chamber section (3). The CSF flow exits chamber sec-tion (3) via an one way valve (V2) an an outlet tube (T2). The outlet tube (T2) delivers the CSF to the desired location.

Granted: 2002-11-12
Abstract: A process is disclosed for transferring in particular colour reproductions to smooth substrates by transferring the reproduction by a photocopying process to a transfer layer applied on a carrier. The transfer layer carrying the transferred reproduction (image) is released by a wet process from the carrier, is applied on the substrate, then cured.      The transfer layer has a sandwich structure with at least two layers, one (first) outer layer that fixes in place and seals when exposed to heat the pigments transferred by photocopying and a (second) layer arranged beneath the outer layer that forms a curing adhesive layer which cross-links with the substrate, fixing in place the transfer layer on the substrate.

Abstract: The present invention relates to a rotor for a dynamo electric machine serving as a synchronous generator as well as being designed to operate as a variable speed motor for starting a prime mover for the synchronous generator.  The rotor is comprised of a rotor core, and a plurality of slots disposed around the circumference of the rotor core and extending along the axial direction of the rotor core.  Rotor windings are accommodated in the slots and wedges are accommodated in the slots over the rotor windings near the surface of the rotor core for preventing the rotor windings from being pushed out of the slots due to the centrifugal force caused by rotation of the rotor.  The wedges where eddy currents flow are formed by Cu-0.05 ~ 4wt% Zr-0.3 ~5wt% Ni-0.2 ~ 1.5wt% Si having a 0.2% proof stress equal to or more than about 20Kg/mm2 and an electrical conductivity equal to or more than about 20% IACS (International Annealed Copper Standard).          Damage of the rotor elements due to electrolytic corrosion are prevented.

Title: Monolithic optical waveguide filters based on fourier expansion
Inventor: HENRY CHARLES HOWARD
IPC: H04J14/02
Filed: 1995-12-13
Granted: 2000-02-15
Abstract: A new type of monolithic optical waveguide filter comprises a chain of optical couplers of different effective lengths linked by differential delays ofdifferent lengths. The transfer function of the chain of couplers and delays is the sum of contributions from all possible optical paths, each contribution forming a term in a Fourier series whose sum forms the optical output. A desired frequencyresponse is obtained by optimizing the lengths of the couplers and the delay paths so that the Fourier series best approximates  the desired response. The filter is advantageously optimized so that it is insensitive to uncontrolled  fabrication errors and is short in length. The wavelength dependence of practical waveguide properties is advantageously incorporated in the optimization. Consequently, the filter is highly manufacturable by mass production. Such filters have been shown to meet the requirements for separating the 1.3 and 1.55µm telecommunications channels and for flattening the gain of Er amplifiers.

Abstract: A vehicle door (40) is provided including a latching mechanism (46) carried by the door constructed and arranged to move between an unlatched relation with a door opening catch and a latched relation with the door opening catch. The latching mechanism (46) includes a movable releasing component (48) constructed and arranged to be in a latching position within the door structure when the latching mechanism (46) is in latched relation with the door opening catch and to be moved from the latching position in a generally downward direction into a releasing position to move the latching mechanism (46) into unlatched relation with the door opening catch.
