Patent CA-2108327-A1 (CA)
Inventor: WEISBECKER RICHARD T
IPC: F24F3/00
Filed: 1993-10-13
Abstract: A two section damper assembly and method of use is disclosed for avoiding stratification of cooled air in an air conditioning system.  The damper assembly is especially adapted for use in variable air volume air conditioning systems that include an economizer.  During the economizer mode of operation, the building in which the air conditioning system is installed is cooled at least partially with outside air as opposed to cooling solely by mechanical means and the volume of air that is required may be relatively low.  The variable two section damper assembly ensures that an adequate volume of cooling air is taken in and that there is adequate velocity of the outside air and return air to ensure mixing of the outside air with the return air in order to avoid the stratification of the supply air that can occur.  The damper assembly is variable in the size of the opened area and in the direction that the individual vanes of the damper assembly are set.

Patent CA-2112223-A1 (CA)
Title: Filling flowing products into receptacles
Inventor: DIVALL JOHN EDWIN
IPC: B65B3/04
Filed: 1992-06-24
Abstract: An apparatus is described for filling a liquid product into containers (12) moving along a linear path. A metering screw (18) is rotatably mounted within a tube (14) extending horizontally above the container path, so as to make sliding contact with the tube interior on either side of a slot (28) which is formed along the bottom of the tube. A space formed within the tube interior around the metering screw forms a distribution chamber for the liquid product, and as the screw rotates the helical gap of its thread uncovers the slot so that liquid product supplied to the distribution chamber forms spaced product streams which move progressively along the tube and fall into the containers beneath. The apparatus can be cleaned easily and is particularly suited for aseptic filling applications.

Title: Very low voltage inter-chip cmos logic signaling for large numbers of high-speed output lines each associated with large capacitive loads
Inventor: WANLASS FRANK M
IPC: H03K17/0814
Filed: 1994-01-21
Abstract: ABSTRACT OF THE DISCLOSURE    A CMOS integrated circuit (IC) device embodiment of the present invention comprises an internal logic circuit operating with traditional 3.3 volt or five volt internal logic levels, an output buffer to convert the internal logic levels to external logic levels of 0.3 volts and an input buffer to convert the 0.3 volt external logic levels to the internal logic levels.  In a CMOS IC device having numerous external output loads including relatively high capacitive values that are driven at very high clock rates, the restricted voltage swings of the 0.3 volt external logic levels permit unusually large numbers of devices to be driven without exceeding a predetermined power dissipation limit of the CMOS IC device.  The low external logic levels further permit electrostatic discharge (ESD) protection to be included on all signal inputs and outputs of the CMOS IC device.  The ESD protection comprises a pair of opposite polarity silicon PN junction diodes in parallel and connected between each signal line and a ground reference.

Title: Production of composite structures using lightweight low cost matrix extender materials
Inventor: CHAPMAN MICHAEL
IPC: B05B7/14
Filed: 1992-08-13
Abstract: A process and apparatus are provided for injecting dry lightweight particulate material into a stream of catalyzed resin. The particulate material is stored in a fluidizing tank (62). The fluidized dry particles are conveyed from the tank (62) under a controlled vacuum created by a low pressure venturi pump (84) through an anti-static conveying tube (112) to an adjustable delivery tube (36) which terminates with a nozzle (52). The nozzle (52) delivers a low velocity controlled spray pattern (50) which coincides with the stream of pressurized resin. Within the venturi pump (84) and opposite to the main low pressure, low volume inlet (102), is a second pressurized inlet (100). This inlet (100) directly controls the degree of vacuum, thereby precisely determining the amount of particulate material delivered to the resin stream. The degree of vacuum can be sensed by a tube (156) connected to the venturi pump (84), and through electronic circuitry is converted to a visual display (160).

Patent CA-2121339-A1 (CA)
Inventor: JONES CRAIG W
IPC: C08B37/00
Filed: 1992-10-14
Abstract: 2121339 9308144 PCTABS00021 A process for oxidising a substrate susceptible to nucleophilic oxidation by reacting a bicarbonate or monopersulphate solution with the substrate is disclosed. In one aspect the substrate is introduced into the reaction mixture in an inert carrier gas, which can also serve to sweep the product out of the mixture. In a second aspect, the oxidant solution is obtained by a two stage neutralisation of a Caro's acid solution, the first stage to e.g. 0.5 to 2.0 and the second stage to about 7 to 9. In preferred embodiments, the substrate is introduced into partially neutralised Caro's acid, and the second stage neutralisation in the presence of the substrate is most preferably carried out with an alkali salt such as sodium bicarbonate. The process can employ relatively low ratios of substrate: Caro's acid oxidant and homogeneous reaction conditions. The process is particularly useful for preparing dioxiranes from ketones.
