Title: Gas spring actuator
Inventor: SNYDER DAVID E
IPC: F16K31/122
Filed: 1991-11-12
Abstract: A gas spring actuator which, when attached to a valve, will return the valve to its initial position after the valve has been moved to a second position by application of a pressurized fluid that opposes the gas spring. The gas spring is charged to a predetermined gas pressure. A hydraulic fluid is applied in an opposing manner to drive the piston in one direction to operate the valve and simultaneously pressurize the gas in the gas spring. Upon removal of the hydraulic pressure, the pressurized gas returns the piston, and the valve, to its initial position.

Title: Modification of endogenous circadian pacemaker
Inventor: CZEISLER CHARLES A
IPC: A61N5/06
Filed: 1990-06-15
Abstract: A method for assessing and modifying the phase and amplitude of the endogenous circadian pacemaker in treating "jet lag"  sufferers, shift workers, advanced circadian phase experienced by elderly subjects, and those with delayed sleep phase insomnia. A  circadian cycle modification capacity assessment method comprises eliminating activity-related factors associated with the sleep-rest cycle which mask the state of the endogenous circadian pacemaker.  Based on either individual or normative assessment data, the circadian phase and amplitude modification method involves application of bright light, and episodes of imposed darkness, at chosen phases. Timing of episodes of bright light by reference to a mathematical model in which the endogenous circadian pacemaker is a second order differential equation. A forcing function in the model is proportional to changes in the cube root of surrounding illuminance. Amplitude of the endogenous circadian pacemaker may be reduced to modify phase.

Title: Gas flow check valve for bottle filling device
Inventor: MONNIG LEONARD W
IPC: B67C3/26
Filed: 1992-09-14
Abstract: ABSTRACT A gas flow check valve for a bottle filling device employs a piston received within a bore which is maintained at the bottom of the filling head vent tube. The piston has a head thereon which is interposed within the flow path of escaping gas during the filling operation. The escaping gas impinges upon the underside of the head and urges the same toward a sealing position. An opposite end of the piston extends downwardly into the bottle being filled. When the level of the beverage within the bottle reaches the bottom of the piston, the buoyancyof the piston, coupled with the forces of the escaping gas impinging upon the piston head urge the piston into sealing engagement, terminating the escape of gas and similarly terminating the inward flow of beverage or liquid, terminatingthe filling operation.
