Patent CA-2096114-A1 (CA)
Title: Radiation activated hydrosilylation reaction
Inventor: BOARDMAN LARRY D
IPC: A61K6/90
Filed: 1991-11-12
Abstract: Numerous patents teach the use of various complexes of cobalt, rhodium, nickel, palladium, or platinum as catalysts for accelerating the thermally-activated addition reaction (hydrosilation) between a compound containing silicon-bonded hydrogen and a compound containing aliphatic unsaturation. Although platinum complexes and many others are useful as catalysts in processes for accelerating the thermally-activated addition reaction between compounds containing silicon-bonded hydrogen and compounds containing aliphatic unsaturation, processes for promoting the ultraviolet or visible radiation-activated addition reaction between these compounds are much less common. This invention provides a process for the addition reaction of compounds containing silicon-bonded hydrogen with compounds containing aliphatic unsaturation and compositions suitable for said process. The process is activated by actinic radiation and is conducted in the presence of a platinum complex having one diolefin group that is eta-bonded to the platinum atom and two aryl groups that are sigma-bonded to the platinum atom and a sensitizer that is capable of absorbing actinic radiation and is capable of transferring energy to said platinum complex such that the hydrosilation reaction is initiated upon exposure to actinic radiation. The invention also provides compositions for use in the aformentioned process.

Title: Integrated personal/cellular communications system architecture
Inventor: LABORDE ENRIQUE
IPC: H04W88/08
Filed: 1993-08-10
Abstract: ABSTRACT       An integrated PCN/DNC system architecture has a switching center, coupled to a public switched telephone (PSTN), which selectively transfers signals between the PSTN and a digital cellular network (DCN) or a personal communications network (PCN) which is allocated a portion of the cellular communications band by a local cellular operator. Each PCN subnetwork of the PCN includes several microcells arranged in a multi-dimensional grid, and the allocated cellular channels are divided into sets assigned to columns of the grid. The allocated portion of the cellular spectrum is reused within each PCN subnetwork by assigning the same set to more than one of the columns so that different communications signals can be transferred over the same cellular channels.

Title: Explosifs
Inventor: HARRIES GWYN
IPC: C06B31/28
Filed: 1992-02-11
Abstract: Composition d'explosif comprenant un agent d'oxydation tel que du nitrate d'ammonium (NA), et un matériau combustible qui peut renfermer un mazout et comprenant également un combustible solide tel que des particules de caoutchouc ou des billes ou des flocons de polystyrène. On incorpore le combustible solide dans la composition pour obtenir une libération commandée d'énergie lors de la détonation de la composition d'explosif. On a remarqué qu'en remplaçant une partie ou la totalité des huiles combustibles liquides par un combustible solide à combustion lente, on ralentit le temps pendant lequel la pression monte lors de la détonation. On peut ainsi produire un explosif à faible énergie par onde de choc possédant une énergie par onde de choc réduite et une énergie lente accrue par rapport aux explosifs classiques, tels que les explosifs à huile combustible au nitrate d'ammonium (HCNA).

Patent CA-2113284-A1 (CA)
Inventor: SOOD PRADEEP K
IPC: H02P6/18
Filed: 1994-01-12
Abstract: A dynamoelectric machine, for example, a brushless permanent magnet motor (M) has a plurality of stator windings (S) and a rotor (T) which rotates with respect to the windings.  Apparatus (10) is provided for controlling winding commutation with respect to the rotor.  A DC bus (14) supplies current to the windings.  The current waveshape has characteristics which are a function of the commutation angle with respect to the windings.  Current magnitude and waveshape are sensed by a sensing unit (22) and the sensed waveshape is sampled to obtain commutation information.  An inverter (20) successively energizes and de-energizes the respective stator windings.  A controller (26) obtains samples of the waveshape, and processes the information obtained by the sampling to control winding commutation.  The controller controls the inverter operation to provide a commutation angle which optimizes motor performance and efficiency for a particular set of motor operating conditions.  To do this, the processor evaluates slope and amplitude information from the sampled DC bus current waveshape, determines if the waveshape corresponds to a desired waveshape representing a desired commutation angle, and adjusts the commutation frequency produced by the inverter, if necessary, to obtain the desired waveshape.

Patent CA-2118880-A1 (CA)
Title: Jpeg/mpeg decoder-compatible optimized thresholding for image and video signal compression
Inventor: RAMCHANDRAN KANNAN
IPC: H04N19/60
Filed: 1994-03-11
Abstract: For encoding signals corresponding to still images or video sequences, respective standards known as JPEG and MPEG have been proposed. These standards are based on digital cosine transform (DCT) compression. For economy of transmission, DCT coefficients may be "thresholded" prior to transmission, by dropping the less significant DCT coefficients. While maintaining JPEG or MPEG compatibility, threshold selection for the DCT coefficients of an image or video frame is based on optimizing for minimum distortion for a specified maximum target coding bit rate or, equivalently, for minimized coding bit rate for a specified maximum allowable distortion constraint. In the selection process, a dynamic programming method is used.

Title: Method for anchoring lengths of additive thread/fiber thread on the back side of a knitted fabric
Inventor: LUND-ANDERSEN BIRGER
IPC: D04B9/16
Filed: 1992-11-12
Abstract: ABSTRACT OF THE DISCLOSURE       A method for anchoring lengths of additive thread/fiber thread in a knitted fabric in an ordinary knitting process, for example, on a circular knitting machine, where a row of vertical needles is continually and successively moved from a lower position up to an upper position and down to a lower position again during formation of knitted stiches interlocked with each other.  The fiber thread lengths that are inserted during this ordinary knitting process are anchored in the knitted fabric by the thread ends of the fiber thread length being deflected backward relative to the knitting direction and brought down between two new stiches formed by the repeated operation of the needles, in two adjacent stitch rows, and being anchored between said stitch rows by the closing of the insertion opening therebetween by the new stitches formed thereafter through the next repeated operation of the needles and by the tightening of the formed stitches.  In this manner the ends of the fiber thread length are securely locked in and project out from the knitted fabric.

Abstract: An injection molding one-piece gate and cavity insert to be mounted between a heated nozzle and a cavity. The insert has a cooling fluid chamber extending around the central gate with a thin cavity wall portion extending between the cooling fluid chamber and a convex portion of the cavity. Alternating frontwardly and rearwardly projecting rib portions extend radially into the cooling fluid chamber to form a pair of tortuous passages between them for cooling fluid flowing each way around the insert from an inlet to an outlet. In addition to providing more cooling because of turbulent flow of the cooling fluid and their increased surface area, these rib portions also substantially increase the strength of the insert to withstand repetitive injection pressure in the cavity.

Filed: 1994-09-15
Abstract: X-ray images are displayed at both high-resolution and high- illumination with annotation superimposed in registration therewith to point out suspected abnormalities identified through a process in which the x-ray images are digitized and the digitized information is subjected to feature extraction processing. For example, the x-ray images are displayed at high resolution and high illumination in the form of x-ray film images displayed on a light box while the annotation information is selectively superimposed on the same image by a separate imaging system co-acting with the light box. In this manner, the radiologist can view either the x-ray film alone, in the conventional manner, or the same x-ray film, at the same position and at the same high resolution and at the same or substantially the same illumination level but with annotation information superimposed and in registration therewith. In addition, alternative ways are disclosed for displaying the high resolution x-ray image and for selectively superimposing the annotation information thereon.
