Patent CA-2131668-A1 (CA)
Inventor: GALLI CAROL
IPC: H01L21/762
Filed: 1994-09-08
Abstract: A shallow trench isolation structure is formed by a process having a reduced number of steps and thermal budget by filling trenches  by  liquid  phase  deposition  of  an  insulating semiconductor oxide and heat treating the deposit to form a layer of high quality thermal oxide at an interface between the deposited oxide and the body of semiconductor material (e.g. substrate) into which the trench extends.  This process yields an isolation structure with reduced stress and reduced tendency to develop charge leakage.   The structure can be readily and easily planarized, particularly if a polish-stop layer is applied over the body of semiconductor material and voids  and  contamination  of  the  deposited  oxide  are substantially eliminated by self-aligned deposition above the trench in the volume of apertures on a resist used to form the trench.

Patent CA-2146048-A1 (CA)
Inventor: HARTUNG JOHN
IPC: H04N7/30
Filed: 1995-03-31
Abstract: A method of coding a video signal at a fixed bit rate with use of a vector quantization codebook, wherein advantageous codebook updates are determined by comparing a coding error associated with a first provisional coding of a frame with a coding error associated with a second provisional coding of the frame. The firstprovisional coding uses a fixed available number of bits to code a frame with use of the unmodified codebook, whereas the second provisional coding uses a modified codebook to code the same frame. However, the second provisional coding codes both the frame and the codebook updates with the fixed available number of bits.The provisional coding having the smaller coding error is selected as the coding of the frame which will be adopted. In addition, the codebook may be replaced with the modified codebook when the second provisional coding is selected. In this manner, the coder will adapt the codebook to the characteristics of the scene.

Title: Nitinol instrumentation and method for treating scoliosis
Inventor: SANDERS ALBERT E
IPC: A61B17/70
Filed: 1993-10-05
Abstract: A method and implant for the surgical treatment of scoliosis is disclosed. The method involves the segmental fixation of a rigid rod or rods (38) to the abnormally curved portion of the spine. The rod is constructed of a shape memory alloy such as nitinol. Prior to implementation, the rod is annealed and contoured into an ideal shape for a given patient. At the time of surgery, the rod is deformed to accommodate the existing curvature of the patient's spine and segmentally fixed thereto. The rod is then inductively heated to the transition temperature postoperatively to effect shape recovery and thereby apply corrective forces to the spine. Also disclosed are clamps (20, 24), constructed of shape memory material, for securing the rod to a vertebra (23, 35).

Title: Fluorescent spectrophotometer system with automatic calibration and improved optics block
Inventor: BROWN CRAIG W
IPC: G01N21/05
Filed: 1995-04-06
Abstract: A spectrophotometer system includes an optics block housing an excitation lamp and a cell for receiving a gas to be detected.  The excitation lamp excites atoms of the gas to be detected to produce photons.  The spectrophotometer system also includes a photomultiplier tube assembly and an analog-to-digital converter.  The photomultiplier tube assembly detects the photons, and produces an analog output accordingly.  The analog-to-digital converter converts this analog output to a digital output.  The photomultiplier tube assembly and the analog-to-digital converter of a spectrophotometer system are calibrated together so that a zero input to the analog-to-digital converter may be defined as an absence of photons.  The optics block is config-ured to minimize scattering of light, without a lens, so that the output of the spectrophotometer system is a function of the number of atoms of the gas to be detected and not of scattered light.

Title: Intrinsically safe power source
Inventor: HUCZKO KEVIN M
IPC: H02H9/00
Filed: 1995-04-07
Abstract: An intrinsically safe power supply unit is provided for conditioning power supplied by a power source. An input power converter connected to the power source receives current from the power source. A direct output crowbar and discrete impedance elements dissipate and limit the energy in the power supply unit that would otherwise be delivered to an external fault. In addition, the direct output crowbar extracts energy from any external storage elements. An adaptive shutdown circuit distinguishes nominal load conditions, including load changes from an external fault. A multistage LC power filter is used to minimize the stored energy that would be deliverable to an external fault or dissipated by the direct output crowbar and discrete impedance elements, The combination of the direct output crowbar, discrete impedance elements, adaptive shutdown detection circuitry and multistage LC power filter significantly improves the level and quality of intrinsically safe power delivered by the power supply unit.

Title: Process and system for the treatment of contaminated oil
Inventor: WILLCOCK RICHARD A
IPC: B01D21/02
Filed: 1995-04-26
Abstract: A process and system for the treatment of contaminated oil laden with particulate material requires the contaminated oil to be agitated thoroughly with a liquid such as water. Once this has been done, the mixture of contaminated oil and water is allowed to settle. During the settling process, particulate material in the mixture settles to the bottom while oil floats on top of the water. The oil is then skimmed off of the top of the water and held in a storage tank. The oil can then be shipped back to the supplier for use as feedstock in oil upgrading processes. The water is then removed and the remaining particulate material is washed yielding clean useable particulate material.

Patent CA-2159543-A1 (CA)
Inventor: WALTER PETER A
IPC: C09J7/38
Filed: 1995-09-29
Abstract: The adhesive bonding strength of a pressure sensitive adhesive on a laminate is selectively modified by applying a discontinuous layer of a non-adhesive material to the pressure sensitive adhesive.  Preferably, the laminate is a preformed, label stock, including a label or substrate having a pressure sensitive adhesive on one surface thereof and a release sheet overlying the adhesive.  The label is first delaminated from the release sheet to expose the oppositely facing surface of the label and the release sheet.  A discontinuous layer of the non-adhesive material is  then  printed  on  either  the  release  sheet  or  the adhesive.  The release sheet is relaminated back onto the label  to  form a  modified  laminate  with  new  adhesive properties.   When the label is then separated from the release layer, the non-adhesive material adheres to the pressure sensitive adhesive to reduce the exposed surface area of the adhesive.
