Patent CA-2145205-A1 (CA)
Title: Surface treatment composition
Inventor: PEDERSEN ARNE
IPC: A23P20/10
Filed: 1993-09-24
Abstract: A composition for use as a substitute for petrolatum and for surface treatment of confectionery, food products and sur-faces which get in contact therewith as well as for external treatment of animals and plants comprises (a) oxidation resistant gly-ceride oil and/or liquid wax, (b) solid wax, which may be omitted if (a) comprises liquid wax, (c) structuring fat, and optionally (d) additions selected from crystallization inhibitors, hydrolysis inhibitors, food product ingredients, additives to food products, diet supplements, bioactive substances, cosmetic ingredients, pigments, and solvents. The combination of oxidation resistant gly-ceride oil, wax and structuring fat provides a composition with a semi-transparent, petrolatum-like structure having a high taste and smell stability, good gloss and anti-sticking effect, regulated adhesion and a very fine crystal structure. The composition is biocompatible by topical and oral administration and may advantageously be used instead of petrolatum and mineral oil based surface treatment compositions.

Patent CA-2154380-A1 (CA)
Inventor: LEE YOUNG W
IPC: H04N5/335
Filed: 1995-07-21
Abstract: The control system controls the operation of a charge coupled device. The operation of the charge coupled device is responsive to a shift clock signal of a given frequency and a shift enable signal. The control system includes a timer for generating one of a number of shift clock signals. Each of the shift clock signals has a different frequency. A programmable register stores a plurality of control bits which may be programmed into the program memory of the control system. A multiplex switching is used for selecting one of the shift clock signals in response to the state of the control bits and directing the selected shift clock signal to the charge coupled device. An address decoder in response to addressing by the microprocessor, generates the shift enable signal which signal is directed to the charge coupled device concurrently with the presence of the selected shift clock signal.

Patent CA-2172160-A1 (CA)
Title: Autonomous cruise control
Inventor: WOLL JERRY
IPC: G01S13/931
Filed: 1994-09-28
Abstract: A cruise control system (14) including a vehicle-borne radar (32) for determining range and closing rate of the vehicle relative to a target ahead of the vehicle. The range and closing rate are used to determine a new set speed for the control system which may be less than but not greater than the speed entered in the cruise control by the driver of the vehicle. The new set speed is selected to prevent the vehicle from overtaking the target, and ideally reduces the closing rate to zero at a predetermined minimum distance from the target. The system also determines incremental movements for the vehicle throttle using a selected gain boost and is designed to minimize throttle jerk. If the target moves out of the path of the vehicle or speeds up, the system adjusts accordingly and eventually allows the vehicle to resume the originally entered speed when possible.

Patent CA-2176409-A1 (CA)
Inventor: HIMAYAT NAGEEN
IPC: H04N7/173
Filed: 1996-05-13
Abstract: A CATV interference cancellation system reduces the presence of undesirable narrowband interference that corrupts return signal transmissions. The cancellation system first acquires a reference signal that contains components related to the interference present in the return signal. The reference signal is processed to derive estimates of the interference components appearing in the return signal and a cancellation signal is generated. The interference cancellation signal is then combined with the return signal, thereby reducing the interference components present in it. The interference cancellation system is deployed at a CATV headend and time division multiple access techniques (TDMA) are used for return transmission. The reference signal is derived from monitoring time slots within a TDMA frame that contain predetermined transmission data. Preferably the predetermined data is the absence of data resulting in an idle time slot. These time slots may be temporarily idle, or may deliberately be left unused to provide a window to a "noise- only" component of the return path signal. The signal thus obtained is passed through the same RF processing stage as the composite return signal and subsequently sampled and digitized. Thereafter, spectrum estimation techniques are applied to the samples of the signal to determine the frequencies of the interfering signals. Once an estimate of the interference frequencies is obtained from the spectrum, the reference signal comprising the same frequencies may be synthesized.

Patent CA-2189019-A1 (CA)
Title: Positioning device and method for radiation treatment
Inventor: LEKSELL DAN
IPC: A61B6/04
Filed: 1995-06-09
Abstract: A radiotherapy appliance having controllable radiation beam(s) which converge on a focus volume wherein an object being irradiated can be movably positioned relative to the focus volume for varying time periods and with varying radiation exposure rates, optimally under control of a computer. The computer controls the focus volume radiation beam size, intensity and exposure time for subareas of the treatment target in response to a radiation dose distribution determined for the treatment target. A determination of the radiation beam size, intensity and dwell time of the focus volume in the target area, is made by initially dividing up the specified treatment area into volume elements or voxels and having biological characteristics of the treatment area assigned to each voxel. The energy deposition incident to each voxel to provide this biological characteristic is then calculated. Finally, from the energy deposition incident on each voxel, the dwell time of the focus volume at particular voxels can be determined. Once the dwell time has been determined, the computer generates a sequence of motor control movements to move the patient with respect to the focus volume such that the focus volume is at a position sufficiently long within the treatment target to deliver the necessary radiation for each voxel.

Title: Fibre reinforced resin composite reinforcing material and method for producing the same
Inventor: TAKEDA TOSHIKAZU
IPC: B29C70/16
Filed: 1995-05-29
Abstract: A reinforcing fiber bundle impregnated with thermosetting resin twisted in a predetermined manner is tightly wound on a surface of the core portion of reinforcing fiber bundle impregnated with thermosetting resin so as to form a forming body.  While this forming body is given a tension so that it can be strained by 500 to 3000 µ/m in the axial direction, the forming body is thermally cured.  Alternatively, a forming body formed in such a manner that a reinforcing fiber bundle impregnated with thermosetting resin is wound round a twisted core portion is set in a curved type die curved at a predetermined radius of curvature, and the forming body is thermally cured so as to manufacture a curved reinforcing composite bar of fiber reinforced resin.     Due to the foregoing, it is possible to provide an inexpensive reinforcing composite bar of fiber reinforced resin of high mechanical strength, which is useful as a substitute material of the reinforcing steel bar or PC steel wire.
