Patent EP-0443320-A1 (EP)
Inventor: ALLINGTON ROBERT WILLIAM
IPC: B01D57/02
Filed: 1991-01-16
Abstract: To collect from an electrophoresis capillary tube containing a liquid separating medium, a sample cup has two wells containing electrolyte. The bottoms of the wells are covered with clamped-on semipermeable membrane assemblies to permit the flow of buffer ions but not the migration of separated sample. Electrical continuity for the electrophoretic migration taking place in capillary tubes is provided through the electrolyte in wells, the assembled semipermeable membranes, electrolyte buffer residing the carrier, the electrode and a conductor leading to electrical ground. Separated zones are detected, electrophoretically eluted or electrosmotically discharged from the capillary tube into the electrolyte in well where they are trapped by the semipermeable membrane in assembly. 
     Initially, the high voltage is turned off by a conventional programmer. An arm is positioned as to hold the capillary tube above the well in a sample cup. A lifting and turning mechanism lowers the arm into the position indicated in the electrolyte in well of the sample cup. After the capillary tube has been lowered into the electrolyte in the well and electrical continuity has been established, the programmer turns the power supply on and electrophoresed and/or electro-osmosed material leaves the capillary tube into the electrolyte in the collecting well. When the sample component of interest has been completely eluted into the well, the programmer turns the power supply off and the lifting and rotating mechanism lifts the support rod, rotates the arm, then lowers the arm, with the capillary tube being in position where it dips into the electrolyte within the carrier and electrical continuity is re-established. The programmer then turns the high voltage on and waste material between collected sample zones is eluted into the electrolyte in the carrier which later may be discarded. When the next zone or peak of desired sample to be collected is about to be eluted, the program turns the power supply off and then lifts the arm, the indexing mechanism advances the carrier one sample cup width, the arm is rotated so that capillary is above the well in the sample cup and the arm holding the capillary tube is re-lowered into the next sample collecting cup. 
     A sample injector includes a vacuum chamber communicating with one end of the capillary tube to pull sample into the other end for a new cycle.

Abstract: Installation for filling and closing bottles filled with a cold beverage is to be designed in such a way that the closures can be sterilised and the bottles closed using the non-sterile tools of the closing device. The installation according to the invention possesses, between the filling device (10) and the closing device (11), a transfer station (12) to which is assigned a magazine (13) for the closures. The closures pass via a slide (14) into the transfer station, where they are applied onto the rim of the bottle. On the way from the magazine to the bottle, they are subjected to steam for the purpose of sterilisation. The installation according to the invention is particularly suitable for bottling all types of juices.

Abstract: Measurements of the flow velocity of a fluid by means of ultrasound are performed, for example, using the known method of differential frequency evaluation. The first step in this case is for the number of ultrasonic wave trains, matched over a constant measurement distance, to be adjusted to a desired number, after which phase regulation is performed. Because of the restricted bandwidth of the ultrasonic transducers, an eroneous number of wave trains can arise and lead to false flow rate values. Such errors are avoided according to the invention by the following method steps. Firstly, the ultrasonic frequencies fLSLV, fLSLR are determined, which arise from the regulation of the number of wave trains during transmission of the ultrasound in the flow direction of the fluid and against it. Furthermore, the ultrasonic frequencies fLLLV, fLLLR are determined for both directions on the basis of the phase regulation. Signals corresponding to these frequency values for fLLLV, FLLLR, fLSLV and fLSLR are fed for evaluation to a microcomputer which uses the frequency deviations fLSLR -fLSV and fLLLR -fLSV and fLLLR - fLLLV to calculate the corresponding flow rates QLSL, QLLL' and compare them with one another. If a deviation is calculated between the flow rate QLLL' and the flow rate QLSL which is larger than the flow rate corresponding to half a phase shift, the flow rate QLLL' is corrected by a flow rate value corresponding to a phase shift of 360 DEG . <IMAGE>

Abstract: A cassette (101) provided with magnetic tape (116) comprises a housing (103) having two pressure-roller openings (110, 111) and one magnetic-head opening (112). The cassette comprises a sliding cover (121) for covering the openings, which sliding cover is movable between a closed position and an open position. The sliding cover comprises a front portion (123) and main portions (125, 127) and has a pressure-roller aperture (133) and a magnetic-head aperture (135). The thickness (t2) of the cassette is 9.6 millimetres, which enables the main portion (127) of the sliding cover to be made wholly imperforate. Thus, it is also possible not to extend the apertures (133, 135) in the front portion of the sliding cover into the main portions (125, 127) but only up to a distance ( x, y ) from the main portions, so that wall portions (132, 134, 136) are present between the apertures and the main portions. This results in a more rigid construction of the sliding cover.

Abstract: Hull cell has been widely used in the plating industry for many years to evaluate the plating chemistry as a function of current densities. However, because of irreproducible mass transfer, Hull cells can only be used qualitatively for process control. A new design of an improved cell with extremely reproducible mass transfer performance utilizes a rotatable cathode, and permits quantitative analysis of the performance of the cell. The improved cell can also be used to study the mass transfer effect on deposit properties and throwing power, which can not be provided by the traditional Hull cell.
