Title: Method for faciliting physical mail delivery using non-physical messages
Inventor: PARTRIDGE B WARING III
IPC: H04L12/58
Filed: 1996-04-01
Abstract: A method for intergrating and facilitating the pick-up of physical mail with non-physical messages is disclosed. A customer desiring pick-up of a letter or other physical item sends an non-physical message, such as e-mail or voice message, to a physical mail carrier or third party having a message receipt facility. Once the non-physical message has been received, conditioning of the message takes place to prepare the non-physical information into information suitable for physical pick-up.

Title: Hydrocarbon gas processing
Inventor: CAMPBELL ROY E
IPC: F25J3/02
Filed: 1996-05-09
Abstract: A process for the recovery of ethane, ethylene, propane, propylene and heavier hydrocarbon components from a hydrocarbon gas stream is disclosed. The stream is cooled to partially condense it, then separated to provide a first vapor stream and a first condensed stream. The first vapor stream is divided into first and second streams, then the first stream is combined with the first condensed stream.      The combined stream is cooled and expanded to an intermediate pressure to partially condense it, then separated to provide a second vapor stream and a second condensed stream. The second vapor stream is cooled at the intermediate pressure to condense substantially all of it and is thereafter expanded to the fractionation tower pressure and supplied to the fractionation tower at a top feed position. The second condensed stream is subcooled at the intermediate pressure, expanded to the tower pressure, and is supplied to the column at a first mid-column feed position. The second stream is expanded to the tower pressure and is then supplied to the column at a second mid-column feed position. The quantities and temperatures of the feeds to the column are effective to maintain the column overhead temperature at a temperature whereby the major portion of the desired components is recovered. In an alternative embodiment, the combined stream is cooled at essentially inlet pressure to partially condense it, then separated at pressure to provide the second vapor stream and the second condensed stream.

Title: Treatment of congestive heart failure
Inventor: BUNTING STUART
IPC: A61P9/00
Filed: 1995-03-30
Abstract: A mammal with congestive heart failure is treated by administering to the mammal an effective amount of growth hormone. Treatment results in increased left ventricular cystolic pressure, increased left ventricular maximum, increased cardiac output, and increased stroke volume index. Treatment also results in reduced left ventricular end-diastolic pressure and reduced systemic vascular resistance. These measurements indicate improvement in cardiac function by increased ventricular contractility and decreased peripheral vascular resistance.

Title: Faucet timer unit
Inventor: HONEY HELEN LORRAINE
IPC: F16K21/04
Filed: 1997-02-25
Abstract: A faucet timer unit (10) having a valve assembly (24) interrupted by a timer mec hanism (26) for operation in an ON period, a DELAY period and an OFF period. During the ON period the valve assembly (24) is activated and water can flow from the faucet, whereas during the DELAY period the valve assembly (24) is deactivated for interrupting the flow of water from the faucet and can not be restarted. During the ON period and the DELAY period a timer control knob (78) is set to "free-wheel" so that it can not be us ed to reset the valve assembly (24) and hence the operation of the faucet timer unit (10) is not able to be defeated by tampering with the timer control knob (78). The faucet timer unit (10) also has a ringer mechanism (28) which includes a thr ee piece cam (142) which controls the relatively complex sequencing of the operation of t he valve assembly (24) and a bell (152).

Title: Polarized superfluorescent fiber sources
Inventor: FALQUIER DARIO G
IPC: H01S3/067
Filed: 1997-04-15
Abstract: A superfluorescent fiber source outputs highly polarized light without a substantial decrease in output power efficiency. According to one embodiment, a polarizer is spliced within the superfluorescent fiber at a selected location along the length of the fiber (e.g., near the middle of the fiber). According to another embodiment, the entire length of the superfluorescent fiber is polarizing to thereby assure that one of the polarizations of light is substantially extinguished while the other polarization of light is nearly double the power which that polarization would have if the polarizer were not present within the superfluorescent fiber. In this manner, superfluorescent sources can be adapted especially for use in fiber optic gyroscopes, or the like, which require highly polarized light, without a substantial reduction in efficiency.

Patent CA-2215280-A1 (CA)
Inventor: CROSBY ROBERT ALLEN JR
IPC: B67D1/14
Filed: 1997-09-10
Abstract: The present invention concerns an air pressure actuated valve for a beverage dispenser. The dispenser includes a plurality of beverage dispensing valves mounted thereto along a front end thereof. Each valve includes an air switch that is pneumatically operable to turn its associated valve on and off. An equal plurality of air actuators are secured to an elongate panel hingedly secured to the dispenser front surface. Each air actuator includes a pressurized chamber and a pliable front surface. Flexible tubes extend between the air switches and the air actuators for communicating pneumatic pressure there between. The air actuators include a graphics layer secured to the front surfaces thereof. In operation, an air actuator is depressed manually whereby pneumatic pressure created thereby in the pressurized chamber is communicated by the tube thereof to its particular air switch. The air switch then serves to operate a solenoid of the valve with which it is associated, resulting in dispensing of the beverage. Release of pressure on the actuator front surface breaks the electrical connection stopping dispensing.
