Title: Method and apparatus for capillary hydrodynamic fractionation
Inventor: SILEBI CESAR A
IPC: B03B5/00
Filed: 1990-03-30
Abstract: This invention provides an apparatus and method for the complete fractionation of submicron particles according to size by capillary hydrodynamic fractionation. This objective is achieved by using small diameter capillaries; introducing a minor fraction of a liquid dispersion of particles to be separated into at least one capillary fraction; passing the minor fraction through the capillary; and, at the exit of the capillary, diluting the minor fraction with the same liquid as is carrying the fractionated sample. These modifications in the flow patterns are essential to the use of capillaries with diameters smaller than 60 microns. This invention is especially adapted for rapid analytical separation of not only rigid colloidal particles but also of soft latexes.

Abstract: Un aimant (20) est fixé sur une patte coulissante (12) située dans un chargeur de bande magnétique (10). Ladite patte peut se déplacer entre une position d'interdiction d'écriture (16), ce qui empêche l'enregistrement sur la bande disposée dans le chargeur, et une position d'autorisation d'écriture (18). Un enregistreur associé comprend deux détecteurs à effet Hall, l'un à côté de l'autre (24, 26). Lorsque le chargeur est positionné dans ledit enregistreur, et en fonction de la position selectionnée de la patte du chargeur, l'aimant se place directement en regard d'un seul des deux détecteurs, lequel est ainsi actionné par ledit aimant. Si le premier détecteur est actionné, un circuit d'interdiction d'écriture de l'enregistreur est excité. Si le deuxième détecteur est actionné, l'écriture sur la bande est autorisée. Lorsqu'il n'y a pas de chargeur dans ledit enregistreur, aucun des détecteurs à effet Hall n'est actionné, ce qui signale l'absence dudit chargeur. Le chargeur et l'enregistreur réalisent ainsi ensemble une interdiction d'écriture, tout en donnant une indication positive de la présence du chargeur dans l'enregistreur.

Abstract: An apparatus (10) for recovering and purifying refrigerant contained in a refrigeration system has a first mode of operation wherein refrigerant is withdrawn from the system being serviced, compressed, condensed and delivered in liquid form to a refrigerant storage means (86). The pressure ratio across the recovery compressor (44) is monitored, and, when the pressure ratio exceeds a value above which the compressor (44) may be adversely affected withdrawal of the refrigerant from the refrigeration system is terminated. The system is then operated in a closed, cooling mode wherein refrigerant recovered from the system and stored in the storage means (86) is withdrawn therefrom by the compressor (44), compressed condensed, and expanded and returned to the storage means (86) to thereby lower the temperature and pressure of the storage means (86) and the refrigerant contained therein. Means for purifying (32) the withdrawn refrigerant are located upstream from the compressor suction port (42) so that refrigerant purification takes place during all modes of operation. When the temperature in the refrigerant storage cylinder (86) falls to a predetermined level the system is returned to the recovery mode. During the second recovery cycle, because of the substantially lower temperature in the recovery system (10), the refrigerant storage cylinder (86) effectively serves as a condenser. 
     The system (10) may be operated in a liquid recovery cycle wherein liquid refrigerant is delivered directly to the storage means (86). The system (10) is shifted from liquid recovery to vapor recovery responsive to, either, a decrease in liquid level increase in the storage means (86), or, several system control parameters. Apparatus for sampling the purity (104) of refrigerant flowing through the recovery system is provided.

Abstract: Components which are contained in a storage bin as bulk material must first be separated and classified prior to assembly. According to the invention, components of asymmetrical design are initially geometrically aligned and are then introduced, sorted, into parallel tracks and continuously guided, the stock of components in the tracks being maintained virtually constant. In this manner, a plurality of parts situated on the same line can in each case be removed batchwise from the end of the tracks and fed to the workpiece holder which has been brought into a suitable position. In the associated device, the sorting device (1, 2) consists of a first plate (10) with shaped recesses for the geometrical alignment of the components, and a second plate (20), having a plurality of continuous grooves (21, 21', ...) aligned in the longitudinal direction of the plate (10, 20) is assigned to the first plate (10), the first plate (10) being arranged as a vibrator plate for the unsorted components (100) above the second plate (20) as a conveying plate for the components (100). The first plate (10) has a sliding base (14) for releasing and a hopper plate (15) for turning the aligned parts. The first plate (10) is subjected to a circular vibration and the second plate (20) to a linear vibration. The gripper (18) takes components, predetermined by a programme, from the sequence of parts at the end of the second plate and feeds them to the workpiece holder. <IMAGE>

Abstract: An exercise system including an exercise device having a user actuatable pedal mechanism (16) coupled to a permanent magnet, DC motor operated as a generator (18) and a load control arrangement for controlling a braking effect exerted by the DC motor on the pedal mechanism (16). The output of the DC motor (18) is connected to a power dissipation circuit including plurality of power MOSFETs (42). The system can be operated in a constant power or a constant force mode. In the constant power mode, the load control monitors the output of the DC generator (18) and compares it with a selected power level and in response to detected errors between the signals, adjusts the conductivity of the power MOSFETs (42) to maintain the power output independent of actuation speed. Current flow through the power MOSFETs (42) is monitored and the relative conductivity between the MOSFETs is adjusted in order to maintain substantially equal current flows through each MOSFET (42). Power for the electronics is obtained from the DC generator (18) using a two-stage power regulation circuit (102) in which the second stage includes positive and negative regulators (302) and the first stage includes a means for limiting the input voltage to the regulators to a predetermined maximum.
