Abstract: CENTRIFUGAL LIQUID PROCESSING SYSTEM     Herbert M. Cullis James H. DeVries Abstract of the Disclosure An intervivos blood processing system for centri-fugally separating red blood cell and platelet components from whole blood includes a separation chamber for separating red blood cell and white blood cell components, and a collec-tion chamber for collecting platelet components.  Each chamber is formed with closely-spaced sidewalls defining respective generally flat interior chambers therebetween and is mounted on a rotatably driven carriage generally perpendicular to a radius of the carriage whereby the red blood cell component is caused to collect in shoulder regions of the separation chamber and the platelet component is caused to collect on the sidewalls of the collection chamber.  The processing chambers are preferably each formed from sheets of flexible hemo-compatible plastic sealed about their periphery to de-fine the chambers therebetween, and are received on the carriage between  removable carrier plates having recesses which define the shape of the chambers under fluid pressure.

Abstract: ABSTRACT OF THE DISCLOSURE           The disclosure describes a transparent electrode for an electrolytic display cell comprising a first transparent conducting oxide layer having a configuration suitable for display purposes and deposited on an electrically insulating transparent support.  The first transparent conducting oxide layer is coated with a thin transparent second conducting layer of an oxide which differs from that of the first layer and which makes it possible under the operating conditions of the cell to limit the overvoltage on the electrode.  The optical transmission and the electrical conduction character-istics of the electrode are slightly reduced with respect to those of the first layer.  The second layer is electrochemi-cally etched and the thus exposed portions of the first layer are chemically etched so as to obtain a conductive coating of a given configuration.

Abstract: ABSTRACT OF THE DISCLOSURE Method and apparatus for installation of a membrane to a finger type electrolytic cell are provided.  The method comprises covering the horizontal surfaces of a cathode of the cell, not opposing an anode with a membrane installation frame having a collar, positioning the membrane substantially parallel to the vertical surfaces of the cathode, and installing and securing the membrane to the collar by a mechanical securing means.  Not only is efficiency of installation for the membrane to the electrolytic cell greatly improved, but also, in the case of an ion exchange membrane, an alkali metal hydroxide liquor containing hardly any alkali metal chloride is produced.  According to the invention, a conventional asbestos diaphragm finger type electrolytic cell is advantageously converted to an ion exchange membrane electrolytic cell.

Abstract: FEED ROTOR FOR AN AXIAL FLOW ROTARY COMBINE              Abstract of the Disclosure The feeding system for an axial flow rotary combine in which the separator is disposed generally fore-and-aft includes a dual auger feeder house in which a pair of side-by-side upwardly and rearwardly inclined augers are driven in such directions that a major part of the crop material handled is conveyed in a concen-trated high speed stream between the augers and delivered in undershot fashion to be engaged by a separator infeed rotor for transfer downstream to a coaxial threshing section.  In the preferred embodiment the infeed rotor and its housing are gener-ally frusto-conical in form, the rotor including a frusto-conical core carrying four equally spaced axially extending tapered feed bars, each bar having a ramp-like cross section, with the rota-tionally leading edge of the ramp radially closer to the rotor axis than the trailing edge.  Each bar carries towards its trail-ing edge a set of angled material control blades which engage the crop material and contribute to its rotational acceleration and, in cooperation with helically arranged lead members on the inside of the infeed housing, displace the material axially as it is carried around the housing.  The feed rotor core is relatively small so that the form of the rotor creates ahead of each feed bar a relatively deep fluted pocket or receiving zone with a converging trailing portion (due to the backward sloping ramp of the feed bar).  The gentle engagement of crop material provided first by the ramp and then by the slippage-permitting angled blades transforms the flow of crop material from a concentrated linear stream, dispersing it into a rearwardly spiraling annulus, around the periphery of the rotor.

Abstract: The location of a number larger than two of pH or pIon sensors for ionic composition control are distributed over the cross-sectional area of the process line. Each individual sensor signal is digitized and converted to its antilogarithm and these antilogarithms are averaged to a control signal in the form of a binary word, for a binary reagent dispensing system. Reagent from this system is transported by a carrier liquid and dispensed from orifices distributed over the cross-section of the process line, downstream of the sensors. Upstream of the sensors, a backmixing passive mixer homogenizes the process stream; downstream of the reagent orifices a non-backmixing passive mixer homogenizes process liquid plus reagent. This control section of the process line may be followed by a second, identical section dispensing diluted reagent, while its averaged control signal may also be fed back to the data processor processing the control signal of the first sections in order to optimize first section dispenser control. The data processors also multiply the composition signal with process stream flow rate as measured by a flowmeter, and shut off the system if flow rate drops below a minimum. A final section containing only distributed sensors followed by a backmixing static mixer for final homogenization may replace or follow the second control section; averaged signal is used for the feedback optimization of the control by the preceding section, and for final monitoring of the adjusted process.

Abstract: L'invention concerne une chaussure de ski, réalisée en matériel plastique, avec coque et jambière séparées.  La chaussure de ski selon l'invention présente une jambière séparée de la coque comprenant une portion située au dessus de la cheville et une portion inférieure qui lie rigidement dite jambière à la semelle.  Les deux portions de la jambière peuvent être façonnées d'une seule pièce ou séparément;  dans ce dernier cas les deux portions sont articulées entr'elles par le moyen de pivots situés dans la région de la cheville.  Avec la chaussure selon l'invention on évite l'inconvénient des chaussures connues à savoir que la coque s'entrouvre dans la zone d'articulation, lors de la flexion en avant de la jambière, ce qui réduit l'effet de serrage de la chaussure sur le pied du skieur, à l'instant même où le skieur doit transmettre au ski, par le moyen de la chaussure, l'impulsion le plus poussée.

Abstract: ABSTRACT Apparatus for printing of toner images wherein characters to be printed are produced on an intermediate carrier (ZT); for example, a photo-conductive drum and transferred at a printing station (US) onto a recording carrier (AT) with continuous movement of the recording carrier.  In order to start and stop the movement of the recording carrier there is provided, behind the printing station, a feed means (VR) engaging the recording carrier (AT) which has a drive shaft (VRW) of a drive installation with an electromagnetic coupling (EMK) and an electromagnetic brake (EMB).  In order to be able to swing the recording carrier (AT) to the intermediate carrier (ZT) and to swing it away, respectively, a polarized drawing magnet (HM) is provided at the printing station.  During starting of the recording carrier the feed means (VR) are first set into motion by the electromagnetic coupling (EMK) and upon reaching the nominal speed the drawing magnet (HM) is energized so that it swings the recording carrier to the intermediate carrier (ZT).  During braking of the recording carrier the drawing magnet is first activated so that it swings the recording carrier away from the intermediate carrier (ZT).  Subsequently, the electromagnetic brake (EMT) is actuated and thus the feed means (VR) are brought to a standstill.
