Patent CA-2194855-A1 (CA)
Title: Process gas distribution system and method
Inventor: SIERK DENNIS A
IPC: G05B15/00
Filed: 1991-08-29
Abstract: A plurality of gas flow control units in cabinets a e 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 location to the control units through a single cable connected to the interface controller,  thus reducing 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.          The  flow control units  are  adapted  to  deliver process gas selectively from one of two supply tanks to any one or all of four different tool locations.  Simple, fast, low-cost purging of the gas delivery conduits is provided to facilitate maintenance and gas cylinder changes.  The pressure measurement and other transducers in the flow control units can be zero-calibrated automatically by computer control.          Installation of the flow control cabinets in plants with existing exhaust fans and ducts of varying size is facilitated by enabling modification factors to be selected by computer control.

Patent CA-2205147-A1 (CA)
Inventor: BRUSS MARIANNE
IPC: A47J36/10
Filed: 1997-05-23
Abstract: The invention is a single utensil that combines the features of a cooking vessel with those of a strainer. The invention comprises a pot having a spout. The lid for the pot has a downwardly extending skirt which includes a straining section. The lid also has locking means on the skirt which cooperate with locking means provided on the inside of the pot. In use, the lid is placed on the pot so that the straining section is not in communication with the spout. In this position, the skirt will seal the opening created by the spout. Once the cooking is done and the user wishes to drain off the excess liquid, he or she rotates the lid to align the strainer section of the skirt with the spout. When the lid is so positioned, the locking means on the skirt of the lid will engage the cooperating locking means on the inside of the pot to lock the lid in place. The pot and lid can then be lifted as a unit to drain the liquid from the pot.

IPC: F23K5/08
Filed: 1997-06-03
Abstract: A heavy oil emulsion fuel combustion apparatus is arranged, in a combustion apparatus using a heavy oil emulsion fuel, to prevent a decrease in the combustion efficiency due to water content in the fuel and to prevent an increase in the sulfuric acid dew point due to water content in the exhaust gas. A heavy oil emulsion fuel 101 from a fuel tank 100 is led to a fuel heater 110 and is heated. Then the heated heavy oil emulsion fuel 102 is led to a water content evaporator 120. In the water content evaporator 120, the heavy oil emulsion fuel 102 is heated by the use of extraction steam from a steam turbine facility 160 or steam produced through a steam converter 166, and the resulting fuel is led to a steam separator 140. In the steam separator 140, the fuel 111 is separated into steam and light oil combustible gas vapor 121 and a heavy oil portion 122, the latter 122 being used as boiler fuel 131. The steam and light oil combustible gas vapor 121 is used as a heat source for heating performed in the fuel heater 110.

Title: System for providing enhanced services in cellular radio telecommunication systems using #ccsc triggers
Inventor: CHRISTIANSEN AXEL M
IPC: H04M3/42
Filed: 1997-06-05
Abstract: Enhanced services are accessed from an enhanced services network element of a cellular radio telecommunications system using a cellular carrier specific code (#CCSC) string based office-level trigger and IS-41 messaging protocol message types. The invention takes advantage of the #CCSC standard to define MSC office-based trigger criteria wherein the dialed digits must start with the "#" character. When a call is received by the MSC in which the digits dialed start with "#" followed by a digit sequence, and an office-based trigger is provisioned for the "#" sequence dialed, the MSC suspends call processing and a service query message is generated and sent to the SCP of the requested enhanced service. The SCP then sends a response message back to the MSC, which resumes call processing in accordance with the response from the SCP.

Title: Miniature electromagnetic microwave switches and switch arrays
Inventor: YIP LAP SUM
IPC: H01H50/00
Filed: 1997-08-22
Abstract: Methods for the fabrication of miniature electromagnetic microwave switches are disclosed in this invention. In one embodiment, on a dielectric substrate, miniature electromagnetic switches for coplanar waveguide transmission lines are fabricated. In another embodiment, miniature electromagnetic microwave switches are fabricated for microstrip transmission lines. The miniature microwave switches are built on a dielectric substrate and are accompanied by miniature electromagnetic coils on the back of the substrate. The switch is controlled by regulating the dc current applied to the electromagnetic coil. A switch is ON when a dc controlling current is applied to the electromagnetic coil and is OFF when the controlling current is cut off. A reverse dc current may also be applied to the electromagnetic coil to repel the top electrode so it does not touch the bottom electrode. The use of reverse current will prevent the two electrodes from sticking together and thus reduce the switching time. For the switch described in the second embodiment, the miniature electromagnetic coils are separated from the signal lines by a grounding metal layer fabricated within the substrate. In yet another embodiment, switches with two electrodes separated by a gap and a third element, a cantilever, are built on a dielectric substrate. Under the influence of a magnetic force, the cantilever will move downwards so that the two separated electrodes are connected.

Abstract: The instant invention provides a process which produces a detergent composition that exhibits improved solubility as well as improved flow properties. The improved solubility can be detected by evidence of increased solubility of the surfactants in the washing solution and/or by the decreased amount of detergent residue left on laundered clothes. It has now been discovered that incorporating nonionic surfactant on and/or in spray-dried detergent granules before cooling the granules and while they are relatively hot, and thereafter cooling and mixing the granules improves the solubility and flow properties of the granules.
