Title: Process for the preparation of cross-linked dexaran in the form of beads
IPC: C08B37/02
Filed: 1966-04-15
Abstract: Cross-linked dextron in bead form is produced by dispersing into epichlorhydrin, in the presence of C10-C18 fatty acids as suspension stabilizers an aqueous alkali metal hydroxide solution of dextran containing 20-50% by weight of dextran, allowing the dextran and epichlorohydrin to cross-link, freeing the cross-linked product from excess epichlorhydrin, and swelling and washing it in hot water. Reaction is suitably effected at 50 DEG  C. or below, and the initial dispersion may be stirred to prevent coagulation.  The degree of cross-linking depends on the amount of alkali initially present, and values from 2.8 up to 8.5 are given in the examples.  Suitably 0.1-2.0% of fatty acids are present.

Title: Process for the Manufacture of Tubular Polyethylene Films
IPC: B29C48/10
Filed: 1968-04-08
Abstract: 1,157,245. Tubular polyethylene films. OSTERREICHISCHE STICKSTOFFWERKE A.G. 8 April, 1968 [20 April, 1967], No. 16882/68. Heading B5B. A process for the manufacture of tubular polyethylene films having a rough surface, comprises extruding the molten polymer through an annular die, inflating the material which issues therefrom in the form of a tube by means of compressed air which is blown in to give a bubble of lesser wall thickness than that of the tube on issuing from the annular gap, which bubble is closed off by means of two rollers, and is cooled in the inflated state, the molten polymer being cooled immediately before it issues from the annular gap, from at least the outside, by keeping the annulus of the die which surrounds the molten polymer at a temperature 100 to 180 C. Preferably, the molten polymer is cooled from both inside and outside, the temperature of the die on the inside of the molten polymer being suitably 140 to 150 C., and the temperature of the die on the outside of the molten polymer is suitably from 155 to 165 C. Polyethylene manufactured by the high pressure process is preferred. In Fig. 1, which shows a preferred blowing head of a side-fed die, the annular gap 1 is cooled by a flow of coolant through outer cooling spiral 2 and inner cooling spiral 3, via inlets and outlets 4 and 5 respectively . An inner mandrel 6 is provided with an air pipeline 7, and the molten polymer enters the blowing head at 8. Cooling can equally well be applied to a blowing head with a central feed, as shown in Fig. 2. If cooling not only outside the annular gap but also inside the annular gap is to be provided, the pipeline supplying the coolant must be passed through one of the spider bars which hold the inner mandrel of the blowing head. Thus in Fig. 2, 1 denotes the annular gap, 2 the outer cooling spiral and 3 the inner cooling spiral, which spirals are fed with coolant through inlets and outlets 5 and 4 respectively. The inlet and outlet 4 for the inner cooling spiral 3 passes through spider bars 9 and 10 respectively, 6 is again the inner mandrel and 7 the air pipeline, and 8 denotes the position of entry of the molten polymer into the blowing head. An example describes the production of film from high pressure polyethylene having a roughened internal and external surface and hence no tendency to block.

Abstract: 911,759. Generating combustion products under pressure. GENERAL ELECTRIC CO. May 20, 1959 [June 2, 1958], No. 17110/59. Class 51 (1). In the combustion equipment shown in Fig. 1, which may be used in gas turbine, rocket and jet propulsion engines, a mixture of fuel and air or other atomizing fluid is injected through a nozzle 5 located on the axis of the flame tube 2 at the closed end 4 thereof. The vertex angle of the conical jet 7 is about 20 degrees, but may be up to 60 degrees. Primary air is introduced through an annular nozzle 9, a circumferential row of ports containing nozzle vanes 10a, 10b, and a circumferential row of flaring nozzles 11, the directions of the primary air jets being such that they assist the fuel jet 7 in producing a toroidal flow 8. The nozzles 11 may be replaced by circular holes, and the pairs of vanes 10a, 10b may each be replaced by a nozzle similar to 11. The toroidal flow 8 retains the particles of fuel (which may be Bunker C oil) in the primary zone for sufficient time to ensure ignition and initial combustion. Secondary air is admitted through ports 12, 13, 14, spaced from the end of the fuel nozzle 5 at respective distances of about ¥, 1“ and 1¥ times the diameter of the flame tube 2, the respective diameters of the ports being about <SP>1</SP>/ 20 , <SP>1</SP>/ 13  to <SP>1</SP>/ 16  and 1/ 10  times the diameter of the flame tube. Additional rows of secondary air ports may be provided. Louvres (not shown) are provided in the flame tube wall for admitting cooling and insulating air to its inner surface. In a modification, Fig. 4, the domed end 4 is replaced by a conical member 15 surrounded by a shroud comprising a cylindrical part 18 and a disc part 17. Primary air enters a chamber 19 through a circumferential row of metering ports 17a and then passes into the flame tube 2 through circumferential rows of plain ports 15a and louvred ports 15b, 15c. Primary air also enters the flame tube 2 directly through an annular nozzle 9c. As before, the directions of the primary air jets are such as to produce a toroidal flow 8. The nozzle 9c may be omitted, the cylindrical part 18 then being smaller in diameter than the flame tube 2 and projecting into it to afford a narrow annular nozzle through which cooling and insulating air enters along the inner surface of the flame tube.

Abstract: 475,280. Comparing &c. colours. WHITEHEAD, E. June 19, 1936, No. 17125. [Class 97 (i)] Apparatus for displaying contrasting and harmonizing colours comprises two or more movable members each carrying a number of colours and means whereby the actuation of one of these members to bring a colour into a given position automatically causes a further colour or colours on the other member or members to be brought into identifying position. The apparatus is especially intended for demonstrating Ostwald's colour theory. In the form shown, a disc 4 bearing a sequence of standard hues is geared to a disc 5 so that the two discs rotate at the same speed in opposite senses. Rotatably mounted on the disc 5 are a number of small discs 14 equal in number to the sections of the disc 4 and each bearing two colours which are analogous to one of the colours on the disc 4. A wall of the casing in which the discs 4, 5 are mounted has windows 22, 23 through which can be seen complementary or contrasting colours of the disc 4, and further windows for the discs 14, an arrow 24 being provided to indicate the particular disc 14 which is analogous to the colour appearing at the window 22. The discs 14 can be rotated relatively to the disc 5 to demonstrate that the two colours on any one of the smaller discs blend to form the corresponding colour of the disc 4. For this purpose the discs 14 are connected by an endless belt &c. 18 passing round a disc 12 having a handle 13 so that by turning the disc 12 all the discs 14 are rotated together.
