Title: Short wavelength ultraviolet irradiation treatment of polymeric surfaces
IPC: C08J7/00
Filed: 1975-04-09
Abstract: 1463286 Arc lamps E I DU PONT DE NEMOURS & CO 9 April 1975 [10 April 1974] 14564/75 Heading H1X [Also in Division C3] A synthetic organic polymer artefact 20 is modified in its surface properties by exposing it in air to intermittent U.V. in the wavelength range 83-133À5 nm. The U.V. is produced by a pulsed A.C. arc between the edges of coplanar carbon-disc electrodes 16, 17 separated by 1-9 mm.: if greater separation is required, interposed transfer electrodes (26, Figs. 2, 3, not shown) are resistance-fed from each main electrode 16, 17. A W-rod exciting electrode 19 may also be resistance-fed from one of the main electrodes. In operation a mains transformer 12 with secondary winding supplying preferentially 8-12 kV, i.e. more than 1 kV per mm. of main electrode gap charges capacitor 15 via resistors 13, 14 which allows an arc to strike once per half cycle. The artefact, typically a contact lens, may be made of 20/80 w./w. methylmethacrylate - perfluoroalkylethylmethacrylates. The radiation is emitted in, for example, 2 see. operating cycles of 0À25 sec. "ON" followed by 1À75 sec. "OFF"; the artefact mounted on a lathe 21 rotating at 1 rev. per 15 operating cycles receives up to 45 operating cycles of U.V., transmitted by virtue of the "windows" of the oxygen absorption spectrum. The artefact becomes more wettable by water, as indicated by reduction in contact angle; other polymers become more strongly adhesively bondable to Al or to themselves.

Title: Water quality analysis system with multicircuit single shell heat exchanger
IPC: F28F27/00
Filed: 1972-03-29
Abstract: 1332096 Tubular heat exchangers BECKMAN INSTRUMENTS Inc 29 March 1972 [2 Aug 1971] 14721/72 Heading F4S [Also in Division B1] A shell and tube heat exchanger 17 used for cooling a plurality of water and steam samples down to a required temperature comprises a plurality of coiled sample-carrying tubes 21 each surrounded by a cylindrical baffle member 25a extending between closure plates 27 and 28 within the shell 18. Coolant water entering the shell through an inlet 23 passes through the cylindrical baffles 25a, 25b &c. and leaves through an outlet 22. The rate of flow of cooling water passing through each cylindrical baffle 25a can be individually varied by a flow control so that the heat exchanger can simultaneously cool down samples entering at widely different temperatures to a common outlet temperature. As shown each flow control takes the form of an apertured plate 42a mounted on a rotatable shaft 43. The degree of alignment or misalignment of the control plate apertures (44 and 45, Fig. 9) with similar apertures 40, 41 at the end of each cylindrical baffle 25a controls the rate of flow of coolant through that baffle. The space surrounding the outside of the cylindrical baffle members 25a, 25b &c. within the shell is filled with a substantially stagnant body of water, water being permitted to enter this space through a suitable aperture (not shown) in the closure plate 27. Each sample-carrying tube has an inlet portion 21a, a coiled portion 21c which may be finned, and an outlet portion 21b. An inner cylindrical baffle 26a serves to reduce the cross-sectional flow area for the coolant. Each tube assembly 21 can be easily removed. In an alternative embodiment (Figs. 10 and 11, not shown), each flow control comprises a disc (51) mounted on a rotatable shaft (52) and adapted to vary the effective cross-section of a single aperture (50) at the end of each cylindrical baffle 25a. In another embodiment (Fig. 12, not shown) the effective cross-sectional flow area into each cylindrical baffle 25a is controlled by a conical valve member (60) movable towards and away from the aperture at the end of the baffle member.

Title: Process for the pyrolysis of hydrocarbons
IPC: C10G9/00
Filed: 1965-04-07
Abstract: In the pyrolysis of hydrocarbons to gaseous olefines in the presence of steam, water is separated from the products and vaporized for use as dilution steam.  In one embodiment, the pyrolysis effluent is quenched with an oil which is then separated by distilling off the lighter materials including water and the oil is cooled prior to reuse as quench by indirect heat exchange with the water, thereby forming the steam.  In another embodiment the water is vaporized by indirect heat exchange with high pressure steam obtained by indirect heat exchange of the pyrolysis effluent with water prior to quench. Naphtha or ethane may be pyrolysed at 700-900 DEG  C., the pyrolysis mixture containing 20-50% by vol. of steam.

Abstract: 1,017,724. Electric resistance furnaces. A. WALZ. April 16, 1963, No. 14790/63, Heading H5H. A melting device, e.g. for use in the production of fibres from glass or minerals, includes two vertical coaxial resistance tubes into the annular space between which the charge to be melted is received, at least one of the tubes having its lower portion of reduced wall thickness, and the two tubes being connected together at their lower ends, adjacent which is an outlet for the melt. Glass 20 is melted, for the manufacture of fibres, in a resistance furnace having a resistive path between the current leads 19 and 4 constituted by an outer tube 1 joined at flange 6 to a further portion 7, 8, 9 of reduced wall thickness, ring 16, and an inner tube 12 having an upper portion 10 provided with coolant channels 11 The glass moves by gravity down the furnace, the intermediate tube 17 being axially adjustable to ensure that the glass contacts the inner tube only when sufficiently fluid to prevent sticking thereto; a further intermediate tube may similarly protect the outer tube 1, which may, alternatively, be vibrated. The molten glass flows through the radial bores 15 and out through aperture 14, the temperature being maintained constant by circuitry controlled by a thermocouple mounted within the inner tube 12. In a modification (Fig. 2, not shown), a plurality of exit apertures for the glass are provided in the annular portion of plate 16 between the inner and outer tubes. Tubes 1 and 10 are of stainless steel, or graphite, and portions 7, 8, 9 and 12 of a platinum alloy.

Title: Process for the manufacture of plastic masses for printing rollers, hectographs and the like
IPC: B41M5/06
Filed: 1930-05-14
Abstract: Containing gelatine and glycerine.-A process for the manufacture of plastic masses for printing rollers, hectographs, &c. or special adhesives composed of gelatine, glue or like colloids and glycerine or glycerine equivalents is characterized by incorporating the gelatine with the glycerine by soaking it therein without the use of heat.  Before soaking, an amount of water corresponding to that desired in the final product may be added to the glycerine, or the gelatine may be previously soaked in the desired amount of water, or it may be incompletely dried during its manufacture.  Glycerine "pearls" are an advantageous form of gelatine to use in the process. In an example 50 parts by weight of glycerine are mixed with 10 parts of water and 50 parts gelatine pearls introduced.  The mixture is allowed to stand for about 4 days with occasional stirring.
