Title: Hot filament method for growing high purity diamond
Inventor: WU CHING-HSONG
IPC: C23C16/27
Filed: 1991-03-15
Abstract: Abstract of the Disclosure A method of growing high purity diamond crystallite structures at relatively high growth rates on a temperature resistant substrate, comprising (a) flowing diamond producing feed gases at low pressure through a reaction chamber containing the substrate, the feed gases being comprised of hydrocarbon devoid of methyl group gases, i.e., acetylene or ethylene, diluted by hydrogen, and (b) while concurrently raising the temperature of the substrate to the temperature range of 600-1000°C, thermally activating the feed gases by use of a hot filament located within the chamber and upstream and adjacent the substrate, the filament being heated to a temperature  above 1900°C, that is effective to generate a substantial atomic hydrogen (H) concentration and carbon containing free radicals.  A substantial additional loss in carbon balance of the gases is triggered at a lower filament temperature indicative of the formation of intermediate substances that stimulate diamond growth. The gases may be mixed prior to passing the filament and may include CO or equivalent gases to enhance diamond purity.  Alternatively, the gases are delivered in a substantially nonmixed condition past said filament and are substantially mixed for the first time at the surface of the substrate.
Patent CA-2038807-A1 (CA)
Inventor: PECK DAVID E
IPC: B60T8/70
Filed: 1991-03-21
Abstract: An air brake system for a truck includes a treadle valve, a pilot control isolation valve, an exhaust valve, a relay valve,  an air pressure transducer,  a wheel speed sensor, an electronic control unit (ECU) and an air brake chamber associated with a brake actuator.  In heavy braking operations, the pilot system pressure rise rate is monitored and restricted by modulation of the pilot control isolation valve.  During heavy braking operations, if braking of the vehicle wheel results  in a wheel velocity change which exceeds a predetermined deceleration threshold, the pressure rise rate is further restricted in attempt to "creep" up on the brake system pressure at which the lock condition is expected to occur.  At another predetermined deceleration threshold, the brake system pressure is vented.  The brake system pressure decreases resulting in a reduction in the applied brake force thereby permitting the vehicle wheel to roll back up to speed.  The roll up rate is a function of the coefficient of friction of the road surface, the loading of the respective vehicle wheel and residual brake force remaining in the system.   Empirical testing has revealed that a close approximation of the friction force available for stopping the vehicle may be made by use of the pilot system pressure when the vehicle wheel  reaches minimum velocity and the time required to reach a certain wheel velocity greater than the minimum velocity.  The friction force may be used to control parameters of operation of the antilock brake system during subsequent antilock cycles.     For example, subsequent cycle brake system pressure rise rate is restricted by values determined from the friction force noted from previous cycles.  Also, the deceleration condition at which the brake system pressure is exhausted and the pressure to which the system is exhausted are determined  from  the  calculation  of  the  friction  force available during previous cycles.

Title: Scene balance calibration of digital scanner
Inventor: COSGROVE PATRICK A
IPC: H04N1/407
Filed: 1991-09-13
Abstract: SCENE BALANCE CALIBRATION OF DIGITAL SCANNER            ABSTRACT OF THE DISCLOSURE          A digital imagery capture and storage mechanism controls the operation of a high resolution digital film scanner such that the scanner scans the image twice, the first scan being used to gather data to calibrate the scanner, and the second scan being used to capture and store a high resolution image. The scanner carries out a low resolution mode, prescan of the color photographic image frame, thereby obtaining a low spatial resolution digitized image. This low resolution digitized image is then analyzed by a scene balance mechanism to determine how the response characteristic of the scanner's imaging pixel array sees the image and encodes its spatial content. The output of this analysis, which represents the color balance content of the digitized image, is used to adjust the sensitivity range of the scanner, so that, during a subsequent high resolution scan of the image, the essential subject matter of the image will fall within the linear portion of the response range of the scanner's imaging pixel array. The high resolution digitized image is then processed by the scene balance mechanism to map the image data into a digitized image having a reduced encoding resolution corresponding to that of an attendant framestore.
