Abstract: A lamp assembly that comprises a hollow arc discharge light source having a center arc chamber containing an arc generating and sustaining medium and first and second ends with an electrode receiving capillary extending from each end and arrayed along a longitudinal axis. The ends are cylindrical in cross-section. An electrode structure is positioned in each of the capillaries and each of these electrode structures comprises a proximal electrode end projecting into the interior of the center arc chamber, a distal end projecting exteriorly of said capillary and an intermediate section therebetween. A first area of the intermediate section is sealed to the capillary in an hermetic manner and a second area of the intermediate section is exposed to the medium. A tubular shroud surrounds the light source and is coaxial with the longitudinal axis. The shroud has two ends. A pair of spring clips, one at each end of said shroud, mount the light source within the shroud. Each of the spring clips comprises a base in a first plane and has an aperture centrally located therein, each aperture of one of the spring clips frictionally engaging one of the cylindrical ends of the light source at a position adjacent the second area of the intermediate section. Both spring clips are electrically connected to a frame, which is electrically to one of the electrode structures.

Title: Natural gas fuel storage and supply system for vehicles
Inventor: GUSTAFSON KEITH
IPC: F02M21/02
Filed: 2003-06-04
Abstract: A natural gas fuel storage and supply system, particularly suited for use in vehicles powered by liquid natural gas (LNG), includes an insulated tank containing a supply of LNG with a headspace there above. A pump and a vaporizer are in circuit between the tank and the engine of the vehicle. When activated, the pump pressurizes LNG from the tank and directs it to the vaporizer where gaseous LNG is produced. The pressurized gaseous LNG is routed to the engine where it is consumed as fuel. An economizer circuit communicates with the headspace of the tank and includes a regulator, a control valve and a flow control device. The control valve opens when the vehicle engine is in operation and the regulator opens when the pressure in the tank exceeds a predetermined level so that LNG vapor from the tank headspace flows to the vehicle engine air inlet where it is consumed. The flow control device, which may be an orifice or a flow control valve, is set to prevent the LNG vapor and air mixture created at the air intake from being combustable in the vehicle engine.

Title: Hydraulic turbine with interblade vortex suppressor
Inventor: COULSON STUART THOMAS
IPC: F03B11/04
Filed: 2003-08-07
Abstract: An improved Francis-type turbine runner. To extend operating range to partial load, inter blade fins partially extend into the flow paths between the runner blades. The inter blade fins correspond in shape and pattern with the shape and pattern of that portion of the runner blades with which the fins coextend along the flow paths between blades. The fins are recessed rearwardly of the flow dividing edges of the runner blades in the flow paths between the runner blades and reduce occurrence of inter blade vortices during partial or low load operating conditions. The shape of the interblade fins is further improved by tilting or sloping the tip of the interblade fin towards the suction surface of the adjacent blade. This creates a small convergence in the flow path between the fin and the suction surface of the blade.

Title: Control apparatus for plant
Inventor: YASUI YUJI
IPC: G05B13/04
Filed: 2003-05-28
Abstract: The present invention provides a control apparatus for a plant, which can suppress excessive correction for a spiky disturbance being applied and maintain a good controllability, when controlling the plant, which is a controlled object, with the self-tuning regulator. A detected equivalent ratio KACT is input to a high-pass filter 33, and a high-pass filter output KACTHP is input to a parameter adjusting mechanism 42. The parameter adjusting mechanism 42 calculates a corrected updating vector (KID . d .theta.  (k)) by multiplying an updating component d .theta. of a model parameter vector by a correction coefficient KID, and adds the corrected updating vector to a preceding value .theta.(k-1) of the model parameter vector, to thereby calculate a present value .theta.(k). The correction coefficient KID is changed from "1.0"  to a value near "0" upon detection of the spiky response where an absolute value of the high-pass filter output KACTHP increases.
