Patent CA-2188741-A1 (CA)
Inventor: GACHER LAURENT
IPC: B22D11/06
Filed: 1996-10-24
Abstract: The nozzle (15) for the introduction of liquid metal (5) into a continuous casting mould for flat metal products comprises two larger sides (2, 2') and two smaller sides (3, 3'), of the type that incorporates at its lower end two holes (10, 10') cut in its lateral wall opposite each other and designed to feed the liquid metal (5) each in the direction of a smaller side (3, 3') of the mould and at least two orifices (16, 16') cut in the bottom of this lower end. A first group (16) of these orifices is arranged at one side of a plane of longitudinal symmetry of the nozzle including the axes of the holes (10, 10') and a second group (16') of these orifices is arranged on the other side of this plane of longitudinal symmetry. The configuration of the nozzle and its various outlets provokes a number of currents of circulation (12, 14, 15, 16, etc.) for the liquid metal in the casting space of the mould. The lower end of the nozzle may consist of a hollow element in the form of an inverted "T" and may incorporate a number of obstacles in its interior placed in the course of the flow of liquid metal.

Patent CA-2190824-A1 (CA)
Inventor: REED STUART EUGENE
IPC: F28F19/00
Filed: 1996-11-20
Abstract: A flexible, pressurized insert for insertion within the hot (evaporator) side of an inclined heat pipe that forms a part of a heat pipe heat exchanger.  This insert is employed in order to prevent such heat pipe from rupturing in the event the working fluid contained therein freezes.  This insert is constructed of a thin-walled flexible material that is capable of being deformed (i.e.  compressed)  thereby absorbing the expansion pressures exerted by the working fluid should the working fluid freeze or be exposed to freezing temperatures.  By such absorption, the outer heat pipe itself will not be over-pressurized which might otherwise lead to its rupture.  Upon the thawing of the working fluid, the pressurized insert (which is at a pressure greater than that of the working fluid in its non-frozen state) will once again regain its shape.

Title: Floating caisson for offshore production and drilling
Inventor: HORTON EDWARD E III
IPC: B63B39/06
Filed: 1997-02-19
Abstract: A floating caisson for offshore drilling and production that includes means for increasing the natural period of the caisson and reducing heave,  pitch,  and roll without increasing the overall length of the caisson.  The caisson is self buoyant by means of buoyancy tanks and is held in position by mooring lines.          The caisson has a center well through which drilling and/or production risers pass.  One or more plates extend radially from the  caisson below the water  surface.    The plates  provide additional mass and resistance to environmentally induced motions and thus increase the natural period of the caisson beyond the periods of maximum wave energy.  This allows the caisson to be designed with a shallower draft than a caisson without the plates that would normally be used in deep water.

Abstract: A series-compensated converter station in an installation for transmission of high-voltage direct current is connected to an alternating-voltage network (N) with three phases (A, B, C, respectively). The converter station comprises at least two direct-voltage series-connected six-pulse converter bridges (SR1, SR2, respectively), a three-phase transformer coupling with two secondary windings (SW1, SW2, respectively), and a star-connected primary winding (PW) with a neutral point (NP) connected to ground as well as a series capacitor unit (CN) for each one of the three phases. Each one of the converter bridges is connected to a respective secondary winding and the primary winding is connected to the alternating-voltage network via the series-capacitor units.  The transformer coupling exhibits a high impedance to zero-sequence currents through the primary winding of the transformer coupling.

Patent CA-2208950-A1 (CA)
Title: Rate control for stereoscopic digital video encoding
Inventor: CHEN XUEMIN
IPC: H04N7/24
Filed: 1997-06-27
Abstract: Rate control in a stereoscopic digital video communication system is accomplished by modifying the quantization level of P or B-frame data in the enhancement layer depending on whether the frame is temporally predicted (from the same layer) or disparity predicted (from the opposite layer).  The invention can maintain a consistent image quality by providing additional quantization bits for disparity-predicted P-pictures, for example, where a P-frame may be encoded from a B-frame in the enhancement layer.  The selected quantization level corresponds to an overall bit rate requirement of the enhancement layer.  For disparity predicted P-frames, the quantization step size is modified according to the activity level of the frame being encoded in the enhancement layer, or of the reference frame, whichever is greater.  Also, image quality is improved and frame freeze up is prevented during editing modes such as fast forward and fast rewind which require random access to the picture data. When the reference frame in the base layer is the first frame of a group of pictures (GOP), the corresponding enhancement layer frame will be encoded as an I or P frame instead of as a B frame to improve image quality and eliminate or reduce error propagation during random access.

Patent CA-2214849-A1 (CA)
Title: Low noise amplifier structure
Inventor: LOUAGIE FILIP MARCEL
IPC: H03G1/00
Filed: 1997-09-03
Abstract: A low noise amplifier structure based on a Differential Difference Amplifier (DDA1) having a differential output (outp, outn) and two differential pairs of input terminals (N1, P1; N2, P2). The input signal (VIN) is applied to terminals (N2, P1) which belong to different differential pairs. In this way, none of the differential pairs receives a high input signal, and hence none of them cause unacceptable harmonic distortion. The dynamic input range is thus high. The gain of the structure is determined by a resistive circuit (R2a, R2a'; R2b, R2b') coupled to the remaining terminals (N1, P2) of the differential pairs. Thecommon mode of these remaining terminals (N1, P2) is, independently from the output common mode, biased at the input common mode via a common mode feedback circuit (DDA2; GL1, GH1, GH3, R2a, R2a'; GL2, GH2, GH4, R2b, R2b') based on a second differential difference amplifier (DDA2). Some switchingelements (GL1, GH1, GH3; GL2, GH2, GH4) allow the gain to be programmed and prevent the common mode feedback circuit from injecting differential noise if the gain is high. The structure is adapted to amplify signals of 1 Vpp with acceptably low distortion.

Patent CA-2215367-A1 (CA)
Title: Signal quality determining device and method
Inventor: BEERENDS JOHN GERARD
IPC: G10L25/69
Filed: 1996-02-29
Abstract: A device for determining the quality of an output signal to be generated by a signal processing circuit with respect to a reference signal is provided with a first series circuit for receiving the output signal and with a second series circuit for receiving the reference signal and generates an objective quality signal by means of a combining circuit coupled to the two series circuits. The poor correlation between said objective quality signal and a subjective quality signal to be assessed by human observers can be considerably improved by coupling a converting arrangement to a series circuit for converting at least two signal parameters into a third signal parameter, and by coupling a discounting arrangement to the converting arrangement for discounting the third signal parameter at the combining circuit.

Patent CA-2228941-A1 (CA)
Inventor: SOANE ZOYA MARTYNENKO
IPC: H01B1/22
Filed: 1996-10-24
Abstract: The invention provides a composite article (24) whose electrical and/or thermal conductivity undergoes a significant change in response to variations in one of several externally controlled thermodynamic parameters, such as temperature, pH, ionic strength, and solvent composition. The composite article (24) is formed by at least three components: conductive filler particles (22), cross-linked polymeric particles (10/12) that are swellable and deswellable, and a solvent mix (20). In the deswollen state, the gel particles (10) occupy a relatively small volume fraction of the composite article (24), allowing the conductive filler particles (22) to be discrete, fully suspended and free flowing in the solvent mix (20). Upon switching to the swollen state, the interstitial volume of the composite article (24) between the cross-linked gel particles (12) diminishes, forcing the conductive filler particles (22) to come into intimate contact with one another, thus creating a conductive percolation network (26). As a result of contact between the conductive filler particles (22), the electrical and/or thermal conductivity of the composi te article (24) is increased.
