Title: Isolation of orgotein
IPC: A61K35/12
Filed: 1972-12-06
Abstract: 1409925 Orgotein DIAGNOSTIC DATA Inc 6 Dec 1972 [7 Dec 1971] 56242/72 Heading C3H A process for the isolation of orgotein from animal tissue involves subjecting a mixture of orgotein and other buffer-soluble proteins from ground up animal tissue to a chromatographic separation by (a) contacting the mixture of buffer-soluble proteins as an aqueous solution (pH of approximately 6) having an ionic strength of less than about 0.01 M with an ion exchange resin (column) having weakly basic groups, thereby adsorbing the orgotein and a portion of the other proteins (haemoglobin and myoglobin) in the mixture on the resin; (b) eluting a portion of the adsorbed proteins from the resin with an aqueous eluant having a pH of approximately 6 and an ionic strength below about 0.02 M; (c) eluting another (orgotein-containing) portion of the adsorbed proteins from the resin with an aqueous eluant having a pH of approximately 6 and a higher ionic strength (of between about 0.02 M and about 0.03 M) than the eluant used in step (b) while monitoring at least one of the A 265  and A 280  absorbances and measuring a proteinbound divalent metal (Cu or Zn) content of the eluate; and (d) separating from the eluate from step (c) the orgotein-containing fraction having an enhanced protein-bound divalent metal content and a diminished A 265  or A 280  adsorbance. If desired, the starting mixture of extracted proteins can be purified with respect to orgotein by fractionation with ammonium sulphate and the substantially pure orgotein product isolated by the process set forth may be further purified by gel filtration or other conventional techniques (described). The preferred ion exchange resins are tertiary or quaternary amino-celluloses and -dextrans (specified). The term "animal tissue" is defined as excluding blood and blood fractions. The preferred material is bovine liver.

Title: Manufacture of Bonded Non-Woven Scrim
IPC: D04H3/12
Filed: 1966-12-20
Abstract: 1,173,748. Laminates. UNION CARBIDE CORP. 20 Dec., 1966 [21 Dec., 1965 (2)], No. 56908/66. Heading B5N. [Also in Division Dl] A bonded non-woven scrim comprises at least two layers, each layer comprising spaced-apart, substantially parallel strands 2, 3, wherein the strands are bondedtogether by a layer 10 (Fig. 4) of thermoplastic resin e.g. polyethylene, polypropylene, polyvinyl chloride, a vinyl chloride-vinyl acetate copolymer, a polyester, a polyamide, a polyurethane or a polyacrylate resting on and covering one surface of the scrim and being supported by the scrim, the individual strands being at least partially embedded in the layer of resin which extends and hangs within the spaces between said strands to a level at least as low as the opposite surface of the scrim. Bonding of the scrim is effected by placing a layer 4 (Fig. 2) of the resin on one surface of the scrim 1, feeding the assembly into a heated zone 6 at a temperature above the melting point of the resin, maintaining the assembly in the zone until the layer melts and collapses in the spaces between the strands of the scrim and cooling. The strands of the scrim may comprise fibres of nylon, polyesters, polystyrene, polyvinyl chloride, polyvinyl acetate, polyolefines, acrylics, cellulose esters, glass, viscose, cotton, wool or hair. Total enclosure of the strands may be effected by the application of heat or heat and pressure to the bonded scrim. The layer may rupture whilst collapsing between the strands. The bonded scrims may be laminated to paper, wood, metal, fabrics or a thermoplastic resin, lamination being effected by the application of heat optionally with the aid of an adhesive e.g. a natural or synthetic rubber, polyvinyl chloride, polyvinyl acetate vinyl acetate/vinyl chloride copolymers, a copolymer of vinyl acetate, vinyl chloride and acrylic acid, nitro cellulose, ethyl cellulose or an animal glue.

Title: Manufacture of flat glass
IPC: C03B18/00
Filed: 1973-12-12
Abstract: 1452625 Flat glass manufacture PILKINGTON BROS Ltd 20 Nov 1974 [12 Dec 1973] 57661/73 Heading C1M In the manufacture of flat glass in which molten glass 7 is advanced on a bath 6 of molten metal in a tank and drawn to form a ribbon 8 of desired width and thickness, the flow of molten metal is constrained at a zone of the bath 6 at which the viscosity of the glass is controlled to regulate attenuation of the ribbon by a first transverse barrier 27 on the floor of the tank at the downstream end of the zone, the top of the barrier 27 being positioned below the level of the bath surface to constrain the forward flow 28 of the molten metal to that entrained beneath the ribbon 8 and counterflow 36 alongside the ribbon and a second similar transverse barrier 37 upstream of barrier 27 to constrain flow of molten metal to a forward flow 41 entrained by the accelerating glass ribbon 8. As shown in Fig. 5, the two barriers 27, 37 may have a number of barriers 42, 43, 44 between and between each pair of barriers the lower layers of molten metal are deflected as at arrow 35 to feed a return flow 39. Each barrier is a carbon bar of rectangular cross-section with a flat top 34 at from 6 mm. to 15 mm. below the surface of the bath 6 and a dovetail base 31 keyed into a matching groove 32 in the floor 33 of tank 1. In an alternative construction, Fig. 8, each barrier comprises a tungsten rod 51 surrounded by a sleeve 50 of hard graphite of such diameter as to leave the gap of 6 mm. to 15 mm. between the top of the barrier and the bath surface. This type of barrier can be positioned as required and held as by carbon forks (52) extending downwardly at each end alongside the ribbon 8 of glass. The ribbon 8 of glass may be constrained by pairs of driven rollers 11, 14, 15, 16 set at angles of 3, 4, 6 and 9 degrees to an axis at right angles to the direction of advance of the ribbon and driven at increasing speeds, 1À5 m/m; 1À8 m/m; 2À4 m/m and 3À4 m/m. The side walls 1 of the tank are inclined inwardly to form shoulders 25 to assist the flow 30 of molten metal. Lateral baffles (45) may be provided extending from the side walls 1 between each pair of barriers with slight overlap. Mixing of the counterflows and flows in the zone between barriers 27, 37 may be assisted by linear induction motors 46 above the bath surface. Further linear induction motors (47, 48, 49) may be utilized when more than two barriers are used. Immersion heaters may be used in conjunction with or in place of the motors (48, 49) at the upstream end of the zone.

Title: Method of and apparatus for increasing webs
IPC: C14B1/56
Filed: 1971-12-14
Abstract: 1368303 Creasing fabrics A MEYER 14 Dec 1971 [14 Dec 1970] 57961/71 Heading D1S A continuous process for producing random creases in a flexible web comprises feeding the web in a spread-out condition to a treatment zone, gathering the web longitudinally and transversely in said zone, and subsequently spreading out the web-again. A leather-like grain is thus produced. In the embodiment of Fig. 4 the web 2 is engaged by disc-like members 17 fixed to rotating shafts 16. The discs 17 are staggered horizontally and preferably vertically, half of shafts 16 being mounted on an upper frame and the remainder on a lower frame. The separation being adjustable. Alternate shafts rotate in opposite directions. The discs may be circular, oval, polygonal (preferably with rounded corners) or a tube bent into an oval shape. Each portion of the web is thus caused to follow a horizontally and vertically sinusoidal path. To avoid overtensioning the web 2 it is gathered together laterally by discs 22 of zone 20, the number of discs 22 and the depth of their engagement with the web increasing in the web feed direction (Fig. 3, not shown). The web may be treated with hot air or steam before, during and/or after passage through treatment zone 12. A drier and/or cooler may follow zone 12. The web may be fed into the apparatus by means of a leader fabric or cloth or between a pair of endless belts or cloths, which may pass through the apparatus. In the embodiment of Fig. 7 steam or a liquid suspension is applied to web 2 by nozzles 26. Heat is then applied by rods 28 or by hot air. The creasing treatment is effected by rotating members 17, whose shafts 16 are carried by arms of at least one pair of crosses 23 which are themselves rotated in opposite directions by shafts 32. By reversing the direction of rotation the web can be run backwards and forwards. In a further embodiment (Figs. 1 arid 2, not shown) the web is fed downwardly between forks (6) mounted in a' staggered vertical array alternatively to the left and right of. the web, each fork being carried on a lever (7) and being swung by its lever from a position at the longitudinal edge of the web to its midpoint, thus repeatedly gathering portions of the web into a skein. The levers are moved by a crank (9) mounted on a vertical shaft driven by a variable speed motor. The random distribution of creases is enhanced by using forks with wedge-shaped recesses or corrugated prongs and/or by a cam action on the forks to cause adjacent pairs of forks to move vertically towards one another whilst in the vicinity of their innermost positions.

Abstract: 1,164,720. Repeaters; transistor amplifiers. SIEMENS A.G. 28 Dec., 1967 [30 Dec., 1966], No. 58837/67. Headings H3T and H4R. Transistor repeater amplifier is fed with power over the line, with the amplifier supply voltage stabilized by Zener diode ZZ. Gas filled overload protectors A1 to A4 are provided at the input and output of the amplifier, of which the protector A3, which is in parallel with protector A4 for A.C. is also connected in parallel with the current supply Zener diode Z2 in series with R5 and L3, the value of R5 being selected so that it limits the current through Z2 on a current surge in the line to a safe valve, the voltage across the resistor R5 being the difference between the breakdown voltage of A3 and the stabilizing voltage of 22. Voltage peaks at the collector of the output transistor are limited by diodes D1 and D2, D2 being biased by Zener diode Z1, while the diodes Z3 and Z4, biased by resistor R7, limits the signal voltage fed to the line, the biasing of the Zener diodes preventing distortion of the output signal. A damping resistor R8 is provided to attenuate oscillations which might occur between the protectors A3 and A4 and the Zener diodes Z3 and Z4. Diodes D3 and D4 limit overloads occurring at the input of the amplifier.

Abstract: 1493580 Burner controls UNITED GAS INDUSTRIES Ltd 17 Dec 1974 [22 Dec 1973 9 Feb 1974] 59687/73 and 6008/74 Heading F4T A control for a gas burning heating appliance (fire &c.), of the kind having a fan 11 for supplying combustion air, and a pilot burner for igniting a main burner, the control providing a stand by condition in which the air fan runs at a reduced speed and the pilot burner, but not the main burner, is operating. In operation, a control knob Fig. 2 is moved toward the "PUSH FOR PILOT" position, whereupon switch S5, Fig. 1, closes so as to supply current to a speed reducer 18 to drive the combustion fan at 25-30% of its full speed. The knob is pushed down to close switches S1, S2, pilot fuel valve 13 is opened, ignition circuit 24 is made, and the pilot burner is ignited. A flame detector 37 supplies a signal through an amplifying circuit 35 to activate a silicon-controlled rectifier 34 and a neon light 36. The knob is now released to thus open switches S1, S2, which cuts off circuit 24, but rectifier 34 maintains a circuit for valve 13 for so long as a flame is detected. This is the "stand-by" position when heat is required, the knob is turned to "FULL ON" position so that switch S3 is closed, which causes the main fuel valve 14 to open, provided a thermostat switch 30 and a time-controlled switch 31 are closed. A relay 32 is operated to close a switch 19, so that speed reducer 18 is bypassed and fan 11 runs at full speed, and simultaneously a switch 21 is closed so as to start a convection fan 12. The main burner is lit by the pilot, but if either of the switches 30, 31, is opened, valve 14 closes, relay 32 allows switch 19 to open and fan 11 returns to the slow running condition, and when switch 21 opens fan 12 stops. Switch 21 may be a thermostat or like heat sensitive means, and reducer 18 may be a resistor or a diode or a combination of these. In a modification Fig. 3, pilot burner 41 is ignited to heat a temperature sensitive circuit phial 45 which sends a signal to ignition circuit 24 inhibiting it from producing further sparks. Switch SW3 is operated to open the main gas valve 14, whereupon a relay 46 is energized to cause switch SW2 to short circuit speed reducer 18 and combustion air fan 11 runs at full speed. Gas line 40 supplies gas in series to pilot valve 13, main valve 14 and pilot and main burner 41, 42.
