Patent CA-2199121-A1 (CA)
Title: Range-gated field disturbance sensor with range-sensitivity compensation
Inventor: MCEWAN THOMAS E
IPC: G01S13/56
Filed: 1995-08-29
Abstract: A field disturbance sensor operates with a relatively low power, provides an adjustable operating range, is not hypersensitive at close range, allows co-location of multiple sensors, and is inexpensive to manufacture. The sensor includes a transmitter (11) that transmits a sequence of bursts (19) of electromagnetic energy. The transmitter frequency is modulated at an intermediate frequency. The sequence of bursts has a burst repetition rate and each burst has a burst width and comprises a number of cycles at a transmitter frequency. The sensor includes a receiver (21) which receives electromagnetic energy at the transmitter frequency, and includes a mixer (22) which mixes a transmitted burst with reflections of the same transmitted burst to produce an intermediate frequency signal. Circuitry, responsive to the intermediate frequency signal indicates disturbances in the sensor field. The burst repetition rate is randomly or pseudo-randomly modulated so that bursts in the sequence of bursts have a phase which varies.

Patent CA-2207132-A1 (CA)
Title: Flow meter that measures solid particulate flow
Inventor: YOUNG GARY C
IPC: G01F1/66
Filed: 1997-06-06
Abstract: A non-contact solids flow meter for measuring solid particulate flow is comprised of a flow tube, a sensor, and an indicator. The product enters the flow tube at one end and flows downward by gravity past the sensor and then exits the flow tube at the bottom. The sensor is placed in a sensor tube at an angle to the flow of particulate solids. As the product passes the sensor signal(low microwave energy), this energy upon contacting the particulates undergoes a Doppler shift which is detected by the sensor. The width of the sensor beam has to be at least the diameter of the flow tube so that it covers the entire cross-sectional area of the flow tube. In this manner, all particulate materials flowing through the flow tube come in contact with the beam and are thus reflected. The instrument is calibrated and algorithms determined from the calibration to cause the indicator to provide a best fit function over the output range of the indicator.

Title: Process and apparatus for purification of contaminated acids
Inventor: BROWN CRAIG J
IPC: B01J41/04
Filed: 1996-01-15
Abstract: Acids contaminated with multi-valent metal salts are purified by a process which involves treatment in an acid sorption unit (ASU) and a nanofiltration unit (NFU). The feed solution can first be delivered to the ASU, which produces two solutions, one high in acid concentration and the other high in metal salt concentration. The high acid concentration solution can be treated in the NFU to produce an acid end product and a reject metal salt solution which can be recirculated to the feed of the NFU. Alternatively, the high metal salt solution can be treated in the NFU, and its permeate recirculated to the ASU as eluate. In an alternative configuration, the feed is delivered first to the NFU. In all cases, the membrane reject solution from the NFU is recirculated to increase the metal salt concentration. A second NFU can be used to process the solution from the ASU which contains a high metal salt concentration.

Title: Blower for moving debris
Inventor: GALLAGHER WILLIAM F
IPC: F04D29/42
Filed: 1997-09-11
Abstract: An improved blower for moving debris on a surface is provided. The blower includes a frame mounted on wheels and a motor mounted to the frame. A blower housing with an inlet opening and a discharge chute is also mounted to the frame. A fan is located in the blower housing and is drivingly connected to the motor to generate an air flow having a predetermined volumetric flow. An adjustable height, pivotable deflector is mounted in the discharge chute to split the air flow into upper and lower portions.      The deflector is pivotable from a first, downwardly inclined position, to concentrate the lower portion of the air flow along the surface to create a lifting force for lifting and moving the debris while the upper portion of the air flow moves the debris outwardly, to a second position, in which the pivotable deflector is upwardly inclined to create an expanded air flow profile. The deflector height is adjustable to adjust the volumetric flow of the upper and lower portions.

Title: Safe and low cost computer peripherals with force feedback for consumer applications
Inventor: BRAUN ADAM C
IPC: H04L29/06
Filed: 1996-09-25
Abstract: A method and apparatus for providing safe and low-cost force feedback peripherals for consumer applications. A device microprocessor (26) local to an interface device (14) is coupled to the host (12) by a first interface bus (24). The microprocessor receives host commands from the host computer on the first interface bus, such as an RS-232 interface, and commands an actuator (30) to apply a force to a user object (22), such as a joystick, in response to host commands. A sensor (28) detects positions of the user object and outputs signals to the host on a second interface bus (25), such as a PC game port bus, separate from the firt bus. A safety switch (41) of the present invention disables the actuator when the interface device is not in use and enables the actuator when an amount of weight over a predetermined amount is placed on the joystick created by a user grasping the joystick.

IPC: C10G21/00
Filed: 1996-12-12
Abstract: Power is generated in an organic Rankine cycle turbine (115) by expanding a stream of solvent vapor (112) produced by a flash drum in a deasphalting unit to produce a stream of expanded solvent vapor (118) that is combined with a stream of solvent vapor and steam from a stripper (122) of the deasphalting unit. Heat is extracted from the combined stream by an organic fluid that is vaporized and supplied to a Rankine cycle organic vapor turbine (155) that produces power and expanded organic vapor. The solvent is recovered from the cooled, combined stream and re-used in the deasphalting unit. Heat extracted from products of the deasphalting unit vaporizes an organic fluid that is expanded in an organic vapor turbine (175) that generates power.
