Abstract: A direct-fired, propane powered steam generator is provided with a carburetor, which receives vaporized propane from a converter arrangement which converts liquid propane to vapor, receives pressurized air and feeds a mixture of vaporized propane and air into the combustion chamber of the steam generator. The amount of air delivered to the carburetor is variable, with the amount of vaporized propane entering the carburetor being determined by the position of a metering valve which varies in accordance with the amount of air passing through the carburetor. The converter arrangement receives liquid propane and is coupled to process water heated in the water jackets of the combustion chamber and adjacent structure, the converter arrangement being designed so that heat from the water is transferred for effecting vaporization of the liquid propane. The flow of liquid propane for combustion in a pilot burner and for combustion in the main combustion chamber may be controlled using various arrangements of solenoid-operated lock off valves and/or vacuum-operated fuel lock off filters and/or air pressure balance control valves.

Abstract: La plupart des procédés automatiques de classification de particules génèrent des erreurs. L'invention concerne un procédé destiné à améliorer la précision de la classification des particules tout en réduisant la quantité de contrôles manuels nécessaires par l'opérateur. On utilise dans ce procédé des poids de classe qui sont des facteurs de correction dérivés par statistique en fonction des erreurs de classification. Un premier poids de classe et un second poids de classe sont respectivement attribués à la première classe et à la seconde classe. Le nombre de particules dans chacune desdites classes est respectivement multiplié par le premier poids de classe et le second poids de classe afin de générer un nombre corrigé de particules dans chacune des classes. Si les particules sont reclassifiées, les poids de classe sont recalculés en réponse à la reclassification. Ce procédé peut être utilisé avec une classification complète dans laquelle toutes les particules d'un échantillon sont classifiées, ou une classification sélective d'un sous-ensemble de particules de l'échantillon.

Abstract: A system and method of packet zone hysteresis for a mobile station is presented. A packet zone hysteresis reset timer is started whenever the mobile station sends or receives packet data and packet data exchange is determined to be incomplete. The packet zone hysteresis reset timer gives a time duration for which packet data exchange must be completed if packet zone hysteresis information is to be maintained. If the packet zone hysteresis reset timer expires before packet data exchange is completed, then the packet zone hysteresis information is cleared. If the mobile station moves to a different packet zone while packet data exchange is determined to be incomplete or packet data is going to be sent to which a response is expected, then the mobile station will perform a packet data reconnect. According to another aspect, upon detecting that a packet data exchange has completed, the mobile station re-activates packet zone hysteresis if it was de-activated from the packet data exchange.
