Patent CA-2139891-A1 (CA)
Title: Method and apparatus for controlling a variable fluid delivery system
Inventor: TOFTE S DAVID
IPC: G05D7/06
Filed: 1995-01-10
Abstract: A fluid delivery control system is provided for controlling a fluid delivery system to deliver a fluid under pressure at a target flow rate.  In a hybrid mode, the preferred fluid delivery control system is responsive to signals from a pressure sensor and a flowmeter.  Primary feedback control is provided using the sensed pressure from the pressure sensor, and the sensed flow rate from the flowmeter is utilized to provide compensation for the pressure responsive feedback control and to provide accurate measurements of flow rate and total flow for the fluid delivery system. The preferred fluid delivery control system is also capable of operating in flowmeter and pressure modes which are only responsive to signals from a flowmeter and a pressure sensor, respectively.  In the preferred embodiment, the fluid delivery control system is utilized in a mobile sprayer system for applying an agent over a surface.  A constant application rate of agent over the surface is maintained by varying the delivery rate of the fluid delivery system with the speed of the sprayer system.

Title: Constant pressure gas cell
Inventor: MITCHELL JOHN R
IPC: G01N21/85
Filed: 1993-07-27
Abstract: A gas analysis cell having a pressure control system elimi-nates pressure variations in the gas cell regardless of changes in restriction, gas viscosity and barometric pressure. Since optical alignement through the gas cell is sensitive to gas pressure, main-taining a constant pressure in the gas cell makes the system more stable.

Filed: 1995-12-18
Abstract: A method of increasing the nutritional value of mycotoxin-contaminated animal feed ingested by an animal by feeding the animal an acid-activated montmorillonite clay simultaneously with the mycotoxin-contaminated or ergot-contaminated animal feed.  The acid-activated montmorillonite clay can be fed to the animal in any form, e.g., granular, powder, pellets and the like or can be admixed with other animal food or feed supplements, so long as the clay is present in the animal's stomach (digestive tract) at the same time as the mycotoxin-contaminated animal feed in an amount sufficient to absorb or adsorb mycotoxin from the digestive tract of the animal and thereby aid the animal in metabolic absorption of nutrients from the contaminated animal feed.
Patent CA-2167789-A1 (CA)
Title: Automatic back water valve system
Inventor: COOK WILLIAM H
IPC: F16K31/163
Filed: 1996-01-22
Abstract: A valve body is formed in two half sections which are secured together to define a drain line passage and to confine therebetween a thin gate valve blade for movement between a lower open position and an upper closed position.  A cylindrical bellows is sealed to the valve body above the passage and is covered by circular top plate which is connected by a rod to the valve blade.  The bellows defines an expandable fluid chamber connected by a bottom port to the drain line passage.  The valve body is connected within a sewage drain line extending under a floor. In the event sewage water backs up within the drain line, air within the bellows is compressed to expand the bellows upwardly for closing the valve.   When the sewage water drains from the drain line,  the air pressure reduces, and the bellows collapses due to the weight of the top cover plate and automatically returns the valve blade downwardly to its open position.

Inventor: SCHNABLE ANDREW THOMAS
IPC: H04M15/00
Filed: 1996-03-11
Abstract: In an automatic message accounting (AMA) record distribution network, a method and system for sorting AMA records by using an area code or numbering plan area (NPA) data array and directory number bit maps to identify AMA records which are of interest to an operation center. Operation centers have access to every AMA record generated by a toll switching network and are initialized with a table of AMA structure and call-type codes, an NPA data array and directory number bit maps. NPA entries in the data array which are of interest to a particular operation center contain pointers (i.e., memory address locations) of the directory number bit maps. As AMA records are received by the operation center, directory numbers which have NPAs of interest to the operation center are compared to directory number bit maps. A directory number of an AMA record which corresponds to a numbered bit position of the directory number bit map is processed by the operation center. AMA records which contain directory numbers which do not have NPAs of interest to the operation center, or which do not correspond to a directory number bit map are discarded.

Title: System and method for reducing erroneous crash discrimination
Inventor: GIOUTSOS TONY
IPC: B60R21/01
Filed: 1995-08-16
Abstract: A system and method for controlling actuation of a vehicle passenger safety device in response to an event possibly requiring actuation of the safety device, wherein a modified differentiated measure is generated from received vehicle acceleration information a(t) by substracting (22) the absolute value of a prior-in-time value (20) therefor from its current value, whereby the distortion introduced by negative prior-in-time values is significantly reduced. The resulting modified jerk measure is more useful in discriminating crash events than is a nominal jerk measure, given the latter's predisposition to fail as a useful measure upon encountering negative prior-in-time values.          .
