Title: Pressure compensating hydraulic control system
Inventor: RUSSELL LYNN A
IPC: F15B11/05
Filed: 1996-04-02
Granted: 2001-03-27
Abstract: An improved pressure-compensated hydraulic system for feeding hydraulic flui d to one or more hydraulic actuators. A remotely located, variable displacemen t pump provides an output pressure equal to input pressure plus a constant margin. A pressure compensation system requires that a load-dependent pressu re be provided to the pump input through a load sense circuit. A reciprocally spooled, multi-ported isolator transmits the load-dependent pressure to the pump input but prevents fluid in the load sense circuit from leaving the loa d sense circuit and flowing through a relatively long conduit leading to the remotely located pump. In a multi-valve array, at least one valve section ha s a backflow-preventing shuttle valve which prevents backflow through the pressure compensation system if a main relief valve is operative.

Abstract: An Electrodeless High Intensity Discharge (EHID) lamp for projection applications. The lamp has a small (nominal dimensions: 2mm I.D., 3mm O.D., 6mm internal length) capsule, which is constricted in a mid-portion thereof. The constriction squeezes the plasma within the capsule and provides a higher power density. This in turn produces a higher luminance in the center of the arc.  This focal point of the projection system is constant over the life of the lamp, owing to the fact that the system is electrodeless. The arc tube or capsule is thickened in the vicinity of the constriction to permit heat transfer through the vitreous silica (commonly called quartz). The thickening carries the heat away from the now hotter mid-portion area. This thickening cools by virtue of increasing the thermal conduction through the glass.

Abstract: A dynamic braking system for a motorized lifting mechanism such as a crane, hoist or the like allows the load to be lowered at a controlled rate during a power failure. An auxiliary power source is activated to apply an excitation current to the stator windings, creating a static magnetic field. When the brake is released the rotor rotates in the static magnetic field, generating an A.C. voltage that is rectified and applied to the stator, thereby increasing the strength of the static magnetic field. An equilibrium is reached, and the load is lowered at a controlled rate. In the preferred embodiment the A.C. voltage is supplied through an adjustable resistor, allowing the lowering rate to be selectively controlled.
