Title: Higher-efficiency cold-cathode fluorescent lamp power supply
Inventor: LIU KWANG H
IPC: H02M3/335
Filed: 1997-03-25
Abstract: A switched-mode power supply for energizing a cold-cathode fluorescent lamp ("CCFL") includes a first semiconductor switch connects in series with a primary winding of a step-up transformer.          The primary winding and a secondary winding, having many more turns than the primary winding, are disposed about a transformer core which has a linear magnetic permeability.   A series connected second semiconductor switch and capacitor connect in parallel with the transformer's primary winding.  A controller circuit transmits signals to turn the switches on and off.  The controller circuit turns the first and second semiconductor switches on and off at a frequency that is higher than a resonant frequency of a parallel resonant circuit formed by the primary inductance of the transformer and capacitance  of  the  capacitor.  A decoupling  capacitor connects in series to a first end of the transformer's secondary winding.   A second terminal of the decoupling capacitor and a second end of  the secondary winding provide ac power output terminals for the switched-mode power supply across which a CCFL may be connected.

Title: Improved system for detecting compounds in a gaseous sample using induced photoionization for electron capture detection
Inventor: WENTWORTH WAYNE E
IPC: G01N27/70
Filed: 1997-08-25
Abstract: This present disclosure is directed toward the measure of very small concentrations of compounds of interest within gaseous samples. A spark discharge system induces pulsed spark discharges across a pair of electrodes within an inert gas in a gas flow chamber. Various reactions are induced by spark interaction with the flow of inert gas, and with any sample or dopant commingled with the inert gas, in the region of the pulsed spark discharge. This induces photon ionization which creates an instantaneous current flow within the gas flow chamber. Current flow is held constant for all concentrations of sample introduced into the gas flow by means of a control feedback system. The output of the control feedback system is indicative of sample concentration. The system responds linearly over approximately five orders of magnitude of sample concentration for use with the sample which will be described and low femtogram sensitivity is achieved.

Inventor: STROCK THOMAS W
IPC: F22D1/28
Filed: 1997-11-12
Abstract: An integral deaerator for a heat pipe steam condenser has a main steam duct connected to a heat pipe steam condenser duct by a riser. The heat pipe steam condenser duct is inclined slightly toward the riser and a weir is positioned at the connection between the riser and heat pipe steam condenser duct to prevent condensate from draining directly into the riser. The heat pipe steam condenser duct has a drain for draining a condensate from within the heat pipe steam condenser duct to a distribution header for distributing the condensate within the riser. Steam is provided to the main steam duct for condensation in the heat pipe steam condenser and while in transit, the steam heats and deaerates the condensate. At least one drain boot is connected to the bottom of the main steam duct for draining deaerated condensate.

Abstract: L'invention concerne un procédé et un dispositif permettant de traiter un liquide d'échantillonnage d'une eau de traitement de l'industrie de la pulpe et du papier, tel qu'un coulis de pulpe ou de l'eau blanche. L'échantillon est traité dans un appareil comprenant une chambre d'écoulement d'échantillon, une chambre d'écoulement de filtrat et un filtre reliant la chambre d'écoulement d'échantillonnage à la chambre d'écoulement de filtrat. Selon l'invention, un courant de liquide d'échantillonnage comprenant des matières solides, telles que des fibres et des charges, de même que des matières dissoutes et colloïdales, est introduit dans la chambre d'écoulement d'échantillon (10), par un orifice d'entrée (12). Un courant principal de ce liquide d'échantillonnage est évacué par un orifice de décharge (14). Un courant de filtrat traverse un filtre (16, 16') et passe de la chambre d'écoulement d'échantillon dans la chambre d'écoulement de filtrat, séparant ainsi, dans le filtre, une fraction prédéterminée de matières solides d'une partie mineure dudit courant de liquide d'échantillonnage introduit. La partie mineure du liquide d'échantillonnage correspond à < 1 %, de manière générale < 0,1 % du volume total du courant de liquide d'échantillonnage introduit. Pour éviter que des matières solides ne se déposent en un mat sur la face d'entrée du filtre, des turbulences sont induites dans la chambre d'écoulement d'échantillon, ou bien le liquide d'échantillonnage adjacent au filtre s'écoule à vitesse élevée.
