Title: Improvements relating to the manufacture of cast iron pipes
IPC: B22D19/00
Filed: 1930-11-01
Abstract: 366,560. Metal pipes. GRAHAMSTON IRON CO., Ltd. and MITCHELL, W. W., Falkirk, Stirlingshire. Nov. 1, 1930, No. 32900. [Class 99 (ii).] In casting pipes with ears for fixing, a hollow sheet-metal shell having the shape of the required ears is inserted in the sand mould during its formation and becomes incorporated in the casting. A shell having the shape of two ears may be formed from one lower and two upper blanks 1, 8 stamped to the required shape to fit a half-pattern of a pipe without lugs. The parts are preferably of tinned iron and are connected by lugs 9. The cast metal flows into the shell and the ears thus formed have a tough exterior. In a modification each shell may have the form of one ear only.

Abstract: 1,148,373. Valves; toothed gearing. PLESSEY CO. Ltd. 15 July, 1966 [2 Aug., 1965], No. 32903/65. Headings F2Q and F2V. [Also in Division F1] The amount of fuel flowing to a gas turbine 63 is controlled by a by-pass valve 3, 4 actuated by a stepping motor 5. The latter receives impulses from a computer 68, each impulse causing a fixed angular displacement of the motor. The rotation of the motor may be converted to linear movement of the valve either by a double reduction gear and screw thread drive (Figs. 3 and 4, not shown) or by an epicylic gear and lever as shown in Fig. 7. In the latter a sunwheel 49 engages planets 50 which in turn engage a fixed annulus 51 and. a free annulus (or part annulus 52) the latter having a slightly different pitch. An arm fast with annulus 52 operates the valve via rod 54 against the action of spring 55. The valve may be a pressure balanced hinged valve (Fig. 2, not shown), a beat lift valve (Fig. 3), a plug-lift piston valve (Fig. 4) which is also rotated by the motor, or a rotary disc valve (Fig. 5) comprising two discs 31, 37 rotated by different amounts via gearing. An annular member 45 carried by disc 31 co-operates with a slot 41 in disc 37 to control flow from the latter to return chamber 46.

Patent GB-904008-A (GB)
Title: Wet spinning of polyethylene
IPC: D01F6/04
Filed: 1960-09-27
Abstract: Polyethylene filaments are produced by extruding a heated solution of the polymer in a volatile solvent downwards through a spinneret through the atmosphere for a distance sufficient to effect evaporation of a small proportion of the solvent but not so great as to cause the polymer to crystallize, introducing the extruded polymer into a quench or precipitating bath to form the filaments, the temperature of the bath being lower than that of the solution, drawing the filaments as they are formed in the bath, thereafter passing the filaments from the bath to a heated aqueous bath and further drawing the filaments in this bath, the stretch ratio in the latter being greater than the stretch ratio in the precipitating bath.  In general suitable polyethylenes have a melt index of 0,4 to 20,0 and a molecular weight of about 20,000 to 200,000.  The first or jet stretch is preferably limited to about 10-50%, preferably 30%, of maximum, while maintaining the second stretch at about 50-95%, preferably about 90%, of maximum.  The polyethylene may be a blend or copolymer of polyethylene with other polymers (of which a list is given), the proportion of polyethylene in the blend or copolymer being not less than about 80%.  The solvent may be toluene, xylene, tetralin, diphenyl, or cyclohexane.  The elevation of the spinneret above the quench bath is usually about 1/8 inch to 2 inches and the concentration of the solution is preferably about 20%.  The quench liquid may be benzene, isopropyl alcohol, chloroform, ether, one of the above solvents, or preferably water. When water is used the dope solvent collects upon the surface of the water and may continually be removed by overflow.  The temperature of the quench bath may be 0 DEG to 80 DEG C., preferably 0 DEG  to 40 DEG C.  The stretch bath is preferably water heated to about 60 DEG -100 DEG C., especially 80 DEG -100 DEG C.  In the examples the spinneret is maintained at a temperature of 110 DEG C. to 125 DEG C. during spinning.  The process enables high molecular weight polyethylenes to be used and filaments of high tenacity and low denier to be produced at high spinning speeds.

Title: Improved manufacture of resin
IPC: C08G63/52
Filed: 1921-12-14
Abstract: Water-resistant resins are produced by heating a polyhydric alcohol with a dibasic, tribasic, or polybasic aliphatic acid with or without an anhydride-forming dibasic aromatic acid or a polynuclear aromatic acid.  Glycerol, glycol, diglycerol, and triglycerol are given as examples of polyhydric alcohols; fumaric, maleic, malic, succinic, and tartaric acids as examples of dibasic aliphatic acids; citric acid as an example of a tribasic aliphatic acid; phthalic acid as an example of an anhydride-forming dibasic aromatic acid; and diphenic, 1 : 8-naphthalic, o-benzoylbenzoic, methylbenzoylbenzoic, and chlorbenzoylbenzoic acids as examples of polynuclear aromatic acids. The reaction passes through three stages.  On gentle heating, there is produced a sticky viscous mass which solidifies on cooling to a fusible solid, soluble in acetone, and rapidly decomposed by cold water; further heating gives a product which is infusible, insoluble in acetone, and is affected by treatment with boiling water for two minutes; still further heating results in the formation of a resin which is insoluble in acetone and other organic solvents, is resistant to cold and boiling water, is unattacked by acids at ordinary temperature, but is decomposed by boiling caustic soda to give the alcohol and the sodium salt of the acid employed in the manufacture or its transformation products.  Fillers, such as fibrous asbestos, cotton, wood pulp, talc, rotten stone, wood flour, and ground asbestos, may be incorporated at any stage before the final heat treatment is applied, and the product may be moulded under pressure before or after the final treatment.  The acetone solution of the first-stage resin is useful as a varnish. Examples are given of the formation of the intermediate and final resins from molecular proportions of glycerol and maleic acid, and of the production of moulded articles containing the final resin from the first or second-stage resins.  Specifications 4147/08, 22449/12, 24060/12, 24254/12, 3271/13, 3566/13, and 22421/13 are referred to.

Title: Improvements in the manufacture of cellulose derivatives and in filaments, films, plastic masses, sizes and the like made therefrom
IPC: C08B15/06
Filed: 1934-11-26
Abstract: Nitrogen-containing cellulose derivatives are obtained by reacting with ammonia a cellulose ester or ether containing an unsaturated aliphatic radicle.  Suitable unsaturated cellulose derivatives are the allyl, vinyl, crotonyl, and styryl ethers, and cellulose crotonate, undecylenate, oleate, linoleate, ricinoleate, maleate, and cinnamate.  The cellulose derivative may contain also saturated groupings.  The treatment with ammonia is preferably carried out at elevated temperature and under increased pressure.  When treating cellulose esters, it is preferable to work in the vapour or the liquid phase under substantially anhydrous conditions in order to avoid saponification of the ester.  In a modification of the process, the unsaturated cellulose derivative may be first treated with a halogenating agent, e.g. chlorine, bromine, sulphuryl chloride, or hydrochloric acid, and the product treated with ammonia.  When halogenating agents are used, the reaction between the cellulose derivative and ammonia may be carried out in the presence of a base containing no replaceable hydrogen atom, e.g. calcium hydroxide, calcium hydroxide, dimethyl aniline, or pyridine.  In examples: (1) allyl cellulose in fibrous form is heated in an aqueous solution of ammonia in an autoclave; (2) cellulose crotonate is heated in an autoclave containing ether and ammonia; and (3) allyl cellulose is suspended in carbon tetrachloride, treated with bromine, washed, and reacted with gaseous ammonia. The products have an affinity for acid wool colours and some for direct cotton colours, and may be used alone or together with cellulose acetate or other organic derivative of cellulose in the manufacture of textiles.  Such textiles have a reduced tendency to fading of anthraquinone dyestuffs used in colouring them.  The products may be alkylated, aralkylated, arylated, or acylated. The nitrogen containing derivatives may be used in the manufacture of artificial filaments, foils, plastic masses, sizes, and the like.  Specifications 394,722 and 404,940 are referred to.
