Title: Light component stripping in plate-fin heat exchangers
Inventor: BERNHARD DENNIS PATRICK
IPC: C10G7/00
Filed: 1996-09-26
Granted: 1999-12-28
Abstract: Light components are stripped from a multicomponent liquid feed mixture in a core type plate-fin heat exchanger by heating and partially vaporizing the mixture during downward flow in one of a plurality of multichannel flow passageways in the exchanger. The vapor thus formed flows upward and promotes vaporization of dissolved light components from the liquid to yield a liquid product substantially free of lighter components. The passageways are disposed in indirect heat exchange with one or more additional groups of passageways, and heat for partial vaporization of the downward-flowing liquid feed mixture is provided by indirect heat exchange with a condensing process stream. Alternatively, this heat is provided by a bottoms stream recovered from distillation of the stripped liquid product withdrawn from the core type plate-fin heat exchanger.

IPC: G01F1/66
Filed: 1997-06-06
Granted: 2002-09-17
Abstract: A non-contact solids flow meter for measuring solid particulate flow is comprised of a flow tube, a sensor, and an indicator. The product enters the flow tube at one end and flows downward by gravity past the sensor and then exits the flow tube at the bottom. The sensor is placed in a sensor tube at an angle to the flow of particulate solids. As the product passes the sensor signal(low microwave energy), this energy upon contacting the particulates undergoes a Doppler shift which is detected by the sensor. The width of the sensor beam has to be at least the diameter of the flow tube so that it covers the entire cross-sectional area of the flow tube. In this manner, all particulate materials flowing through the flow tube come in contact with the beam and are thus reflected. The instrument is calibrated and algorithms determined from the calibration to cause the indicator to provide a best fit function over the output range of the indicator.

Abstract: L'invention concerne un synthétiseur de fréquences (200) qui utilise un synthétiseur numérique direct (204) pour générer un signal périodique de grande précision. Le signal de sortie du synthétiseur numérique direct (204) est filtré dans un filtre passe-bande utilisant une boucle à phase asservie de nettoyage (214) pour produire un signal de référence de pureté spectrale et favoriser un temps de stabilisation globalement rapide. Une deuxième boucle à phase asservie ou boucle primaire (220) présentant un temps de stabilisation beaucoup plus rapide que la première boucle à phase asservie (214) ajuste la fréquence du signal de référence généré par la boucle à phase asservie de nettoyage (214). Dans un mode de réalisation, le synthétiseur de fréquence à synthétiseur numérique direct (204) présente un convertisseur numérique-analogique (206) couplé à la phase à boucle asservie de nettoyage (214). Un autre mode de réalisation (300) transmet le bit de poids fort (310) ou bit de dépassement de capacité provenant de l'accumulateur du convertisseur numérique-analogique (306) à la phase à boucle asservie de nettoyage (318). Dans encore un autre mode de réalisation (400), on utilise un appareil de commutation pour dériver la boucle à phase asservie de nettoyage (410) lors de sa stabilisation sur une nouvelle fréquence.

Abstract: A video camera apparatus (1) and a video surveillance system having a video camera are provided with a video compression unit (50) which utilizes quantization for spatial processing and motion vectors f or temporal processing. The camera apparatus and surveillance system include a camera (10) with an adjustment mechanism (18) which allows panning, tilting, zooming and focusing of the camera. The adjustment mechanism has a device for generating adjustment indication signals which indicate the state of adjustment of the camera. The adjustment indication signals are generated by a remote control panel or by means of transducers which detect the state of panning, tilting, zooming or focusing. Spatial or temporal processing are traded off, depending on whether the adjustment indication signals indicate movement of the camera or zooming or focusing of the lens. Compressed video signals are received by a monitoring station (220) for decompression and display.

Abstract: An ultrasonic sensor detects whether a piston is at the lowest position. The sensor is not affected by the environment or damaged by contact with other objects. The sensor is located in the bottom of a mast cylinder, transmits ultrasonic waves to the bottom of a piston and receives ultrasonic waves reflected by the piston. The sensor then outputs electric signals based on the received ultrasonic waves. The ultrasonic sensor is electrically connected to a transmitter-receiver, which, in turn, is electrically connected to a controller. The transmitter-receiver includes an ultrasonic wave generator and sends ultrasonic wave transmitting signal having a predetermined frequency to the ultrasonic sensor based on control signals from the controller. The controller measures time from when it outputs the ultrasonic wave transmitting signal to when the sensor receives a reflected wave. The controller then compares the measured time with a threshold value thereby judging whether the piston is at the lowest position.
