Title: Improvements in screening apparatus
IPC: B07B1/28
Filed: 1920-07-02
Abstract: 145,746. Uhlarik, J. C. June 16, 1919, [Convention date]. Sieves with compound or variable motion.-In screening-apparatus of the kind in which the frame carrying the perforated screen plate receives a substantially circular movement, the screen plate 61 is connected to the frame so as to be movable away from and towards the frame in such a manner that at certain points in the movement of the frame the plate lags behind and moves away from the frame, and then returns into sharp contact with the frame or with stops thereon to produce a succession of jars or shocks. The screen frame is formed of angle irons 56, 57 and is supported on eccentrics formed on parallel shafts 22, 23. The shafts are mounted in bearings carried by pillow blocks 16 - - 19 adjustably mounted in the main framing 10 of the apparatus. The shaft 22 carries at one end a driving pulley 44, and at the other end a sprocket wheel 32 connected by a chain 24 to a sprocket wheel 45 on the shaft 23. The eccentric portions of the shafts are mounted in bearings connected to the side angle irons 56 of the screen frame, the bearings 70, 71 for the shaft 22 being free to move in the direction of the length of the screen to provide for variation in the distance between the. centre of the shafts. Adjustable counterweights 81, Fig. 5, are carried by split collars 35 mounted on the shafts adjacent the eccentrics, the counterweights being placed opposite to the throw of the eccentrics to relieve the pillow blocks and the members supporting them from vibration. The ends of the screen plate 61 are secured to the end irons 57 of the screen frame by screws 62, and the sides of the plate normally rest on stops or spacers 63 carried by the side irons 56. When the apparatus is in use for screening purposes, the rotation of the eccentrics causes the frame to move in a circular orbit represented by the line 84 in Fig. 9, which represents diagrammatically the movement of the middle portion of the screen frame and plate. The screen plate lags behind the frame at the upper part of the movement and follows the path represented by the line 85 during the downward movement of the frame. During the succeeding upward movement, the spacers 63 come into sharp contact with the plate with a jarring action tending to set up high-frequency vibrations in the plate, as indicated at 88.

Title: Treatment of water-soluble cellulose derivatives containing hydroxyethyl groups and products obtained thereby
IPC: C08B11/08
Filed: 1961-05-26
Abstract: The viscosity in aqueous solution of a watersoluble cellulose derivative containing hydroxyethyl groups is increased by heating the cellulose derivative in solid form at 80 DEG -200 DEG C. until an increase in solution viscosity is obtained.  Preferably, heating is effected at 100 DEG -175 DEG C.  Specified cellulose derivatives include hydroxyethyl cellulose, ethyl hydroxyethyl cellulose, methyl hydroxyethyl cellulose, hydroxyethyl hydroxypropyl cellulose, and hydroxyethyl celluloses containing other substituent groups, e.g. carboxymethyl, carboxyethyl, sulphate, sulphoethyl and cyanoethyl groups.  To minimize thermal degradation, the cellulose derivative may be heated in an inert atmosphere, e.g. of nitrogen or carbon dioxide, or in vacuo, and in general the duration of treatment is longer at lower temperatures and shorter at higher temperatures. Viscosity increases of up to 195% are exemplified.  The higher viscosity of the product is due to the introduction of -OCH2 CH2O- cross-links between the molecules.

Title: Electrokinetic streaming current detection
IPC: G01N33/49
Filed: 1974-05-02
Abstract: 1463902 Electrokinetic streaming current measurement, characterizing biological material GENERAL ELECTRIC CO 2 May 1974 [2 July 1972] 19359/74 Heading G1N Electrokinetic streaming current measurement is carried out in apparatus which oscillates an electrolyte in opposite directions alternately through a flow constriction and measures the current between electrodes mounted in the electrolyte on each side of the constriction. The constriction is preferably a capillary tube 11 and when the inside of this tube is coated with a biological material, the variation of the potential obtained by amplifying and rectifying the streaming current with electrolyte pH is characteristic of the biological material. Addition of a second biological material to the tube and subsequent determination of the potential-pH curve determines whether the materials have reacted since, if they have, the curve will characterize the second material which now coats the first. As shown, the capillary 11 is removably connected to electrolyte chambers 12, 13 by seals 11a, 11b. Oscillation of the electrolyte is produced by reciprocation of the pistons in cylinders 18, 19 which connect to the electrolyte chambers by pneumatic couplings 10. The oscillation frequency is between 0À3 and 2À0 Hz which ensures turbulent flow in the tube. Reversible electrodes e.g. platinum gold, silver and silver/silver chloride in the electrolyte chambers are connected to an amplifier 24 for the A.C. current generated, rectifier 26 and recorder 27. In operation, the initially coated tube 11 is inserted into the apparatus, the electrolyte chambers are filled through the associated valves and the voltage is measured at different electrolyte pH values. The pH is controlled externally by a glass measuring electrode in a titration system. Valves 28 and 29 then close the ends of the tube, the valves in tubes 33, 34 are opened and after rinsing, the second material is passed into the tube and lift for a time before rinsing. The new pH/voltage curve is then determined. The tube may be glass, optionally with a surface methylation, omination, octadecylation or silicone coating treatment or may be polyethylene. The first layer may be chemically bonded to the tube. Various biological materials which may be used as coatings are disclosed. In particular the apparatus may be used for antigen-antibody tests; measuring the compatibility of biological and non biological materials, identifying biological materials and for detecting hormones, enzymes and metabolites by the immune assay procedure.
