Title: Colour filters for liquid crystal cells
Inventor: CARRINGTON ANDREW N
IPC: B41M5/035
Filed: 1991-01-30
Abstract: ABSTRACT    A method of manufacturing a colour filter for a liquid crystal cell comprises forming a plurality of patterns, each of a respective dye intermediate material, on a carrier element. The patterns of dye intermediate materials are then brought into contact with a substrate layer, supported on a glass substrate, under the application of heat and pressure.   The substrate layer, such as a polyacrylonitrile layer, contains free acid groups which interact with the dye intermediate materials to form the colours of the colour filter in the substrate layer.     The method permits the actual formation of the colours on the substrate to be effected in a single alignment step, minimising wastage of the relatively expensive glass substrates.   Furthermore, as the dyes providing the colours of the filter are chemically part of the substrate layer, they are very resistant to leaching by the liquid crystal materials.

Inventor: TOPNIK BRIAN H
IPC: C02F3/00
Filed: 1991-04-26
Abstract: ABSTRACT       A sequencing batch reactor is controlled to provide an  effective,  efficient  treatment  of  raw  waste  water.          Controls include regular withdrawal of mixed liquor during each cycle of operation.   The withdrawal is volumetrically controlled to provide a sludge retention time of 5 to 10 days in the system.  This produces a carbon and nitrogen oxidizing bacterial  culture with good setting properties. Hydraulic loads  in  the  system  are  controlled  according  to  liquid levels, while the bacterial processes are controlled by timed sequences.   A storm control procedure monitors the influent rate and shortens the cycle times according to the magnitude rate,  to  increase  the  system  capacity.   The  system  also includes a novel  effluent withdrawal  system,  with a check valve controlled intake about midway up the reactor.  This is trouble-free,  with the check valve preventing sludge entry into the effluent withdrawal  and maintaining prime on the effluent withdrawal pump.

Title: Integral intracranial pressure monitor and drainage catheter assembly
Inventor: HALL JOHN P
IPC: G01L9/00
Filed: 1990-10-10
Abstract: A monitor-driven intracranial catheter assembly including a dual lumen catheter for monitoring intracranial pressure via a pressure sensor located in one lumen while simultaneously draining cerebrospinal fluid through the other lumen. The pressure sensor is preferably a spectral modulation sensor that communicates with a photodetector apparatus by means of a single optical fiber, thus minimizing the diameter of the catheter. The photodetector is self-correcting for signal errors caused by temperature change, changes in intensity of the input light, and transmission losses within the optical apparatus.      Moreover, the photodetector operates off the output voltage of the standard hospital monitor by "scaling" the signal from the monitor to provides a pressure measurement signal that emulates the output of a piezoresistive strain gauge sensor or Wheatstone bridge. Therefore, the entire catheter assembly is designed to be used with any of the common types of hospital monitors. The pressure monitoring catheter assembly can be used in any situation requiring very sensitive pressure measurements and can be zeroed and calibrated in situ.

Patent CA-2050247-A1 (CA)
Inventor: SIERK DENNIS A
IPC: F17C13/02
Filed: 1991-08-29
Abstract: A plurality of gas flow control units in cabinets are connected to distribute process gas, on demand, to a plurality of utilization locations known as "tool" locations in a semi-conductor manufacturing plant. Each gas flow control unit is connected to a single tool interface controller over a single communications cable. The status and operational characteristics of the individual units are communicated through the tool interface controller to a supervisory control computer by means of polling. Each flow control cabinet has its own data processor, and can be operated alone. Also, the supervisory computer can be used to operate each cabinet, as well as to monitor operations of the system. Gas demand and other signals are communicated from each tool locations to the control units through a single cable connected to the interface controller, thusreducing the original wiring cost. Changing the communications path to accompany a change of the tool to which a given conduit in one of the cabinets delivers its gas can be done quickly, in software, with a few keystrokes. Mechanical re-wiring is not needed.

Abstract: The method and equipment for keeping locks free of ice utilises the natural energy resources of the waterway itself. Gravity is utilised to conduct warm water from the depths of the upper waterway via a pipe (1) into the lock where it is distributed by a network of pipes punctuated with holes (3) along the lock floor and around the lock gates. Cooled water is discharged through outlets (6) located in the lower lock gates or lock wall just below the level of the upper waterway. Warm water can effectively be brought to the surface by the use of compressed air conducted to the lock floor either through a special network of pipes or through the existing system (3). The piping may be laid on or under the lock floor. Heatloss can be reduced by insulating the sides of the lock and by fitting the lock with a cover the underside of which is coated with a heat-reflecting material. All the necessary equipment for maintaining an ice-free lock can be installed in both already existing and new locks, thus facilitating inland navigation all year round.
