Title: Liquid hydrocarbon skimmer systems and methods of monitoring leaks in hazardous liquid tanks
Inventor: HORNER JOHN A
IPC: B01D17/02
Filed: 1991-11-20
Abstract: ABSTRACT OF THE INVENTION A floatable liquid hydrocarbon skimmer system for monitoring possible leaks in hazardous liquid tanks incorporates a vertically disposed tubular housing having an upper end with passages to admit liquid and provides a lower collection chamber for recovered hydrocarbon liquid.  The housing has a hydrocarbon liquid-water separator associated with the chamber which has a capillarial filter which will pass only the hydro-carbon liquid through to the collection housing, while being impervious to the passage of water.  A wick may be associated with the filter to draw the hydrocarbon liquid to the filter and a valved outlet passage associated with the collection chamber permits emptying of the collected hydrocarbon liquid back to the tank.
Patent CA-2058316-A1 (CA)
Title: Bi-functional transfer foot
Inventor: TRUDEAU ALLEN E
IPC: B29C31/08
Filed: 1991-12-23
Abstract: A bi-functional transfer foot that is structurally configured and operative to provide automated handling of preimpregnated composite materials.  The transfer foot includes a valve member having a knock-off stem movably mounted in a housing, a solenoid valve and fluid fine interconnection to vacuum and pressure sources, and a control subsystem for regulating the operation of the transfer foot.  The transfer foot is bi-functional for "ON" and "OFF" operation. A control signal issued by the control subsystem turns the transfer foot "ON" wherein vacuum forces causes a first displacement of the valve member within the housing to provide a vacuum force for engaging and retaining the tacky surface of preimpregnated composite plies.  Termination of the control signal causes the solenoid value to exert biasing forces to return the transfer foot to the "OFF" state wherein the transfer foot utilizes forces to cause a second displacement of the value member within the housing that provides a  mechanical force via the knock-off stem to disengage and release the tacky surface of preimpregnated composite plies.  A multiplicity of bi-functional transfer feet may be arranged in an array to define automated material handling apparatus for preimpregnated composite plies. Individual transfer feet may be automatically, selectively, activated to form predetermined combinations to match the wide variety of sizes and shapes or patterns of preimpregnated composite materials pre-cure processed via automated composite material manufacturing systems.

Title: Practical simple single supply integration devices
Inventor: WEI GE DAVID
IPC: G06G7/186
Filed: 1993-07-13
Abstract: Practical Simple Single Supply Integration Devices Owner and Inventor: David Wei Ge ABSTRACTS Integration devices can find many applications in electronic equipment. An integration device usually must involve a phase inversion, hence it must operate on two power supplies, one positive supply, one negative supply. For battery powered devices, it is ideal to use just one power supply. Before the inventor's inventive work, there were no practical simple single supply integration devices. Although two capacitors could be used to form a single supply integration device, the two capacitors used must be exactly the same value. It is difficult to have two capacitors to have exactly the same value. The inventor invented two practical single supply devices, one of them only requires to have two same value resistors instead of two same value capacitors. Because of this invention, very simple and low cost single supply integration devices are realized.
