Title: Improvements relating to steam heating apparatus
IPC: B61D27/00
Filed: 1929-07-11
Abstract: 334,326. Barty, T., Brackenbury, A. G., and Westinghouse Brake & Saxby Signal Co., Ltd. July 11, 1929. Addition to 286,782. Radiators. - The steam heating apparatus for railway vehicles described in the parent Specification is modified to make the valve more readily accessible. The outflow and return conduits 1, 2 are connected to a casing member 4 having a steam inlet 5 and drain passage 8. A valve member 7 is mounted in a cylindrical member 9 adapted to slide axially in the casing 4, and a packing 10 pressed by a spring is provided to prevent escape of steam. A pair of rods 12 extend one along each side of the conduit 2, and pass through and are secured to a member 11 engaging in a transverse recess in the casing 4. The position of the valve 7 relatively to its seating is adjusted by means of the nuts 13, and the valve controls the steam inlet automatically by means of the difference in expansion between the conduit 2 and rods 12. The member 9 carrying the valve 7 may be withdrawn for inspection or repair by removing the nuts 13 from the two rods 12.

[Class 83 (iv).] Mandrels.- Tubes are rolled on a plug rolling mill by using two or more unconnected plug mandrels arranged one in front of the other. A tubular bloom e, as shown in the Figure, is first passed between rolls a, b, arranged for tubes of circular or oval cross section in conjunction with a plug mandrel c, initially secured to the free end of a mandrel rod d, causing a reduction of the tube wall from s to s<1>; rod d is then removed, the plug c remaining within the tube which is withdrawn from the rolls. A plug mandrel f, larger than the plug c, is next secured to the end of the rod d and the rolling recommenced; after a short interval the mandrel f reaches the mandrel c and rolling is continued with the two plug mandrels moving together. The external diameter of the finished tube may be made greater or less than that of the bloom by using the above method.

Title: Improvements in or relating to pectin preparations
Inventor: OLLIVER MAMIE
IPC: A23L29/231
Filed: 1956-07-12
Abstract: A composition which forms a table jelly when mixed with milk comprises an aqueous solution containing low methyl pectin substantially completely dispersed therein and sweetening and/or flavouring constituents, the pH of the solution being within the range of 3.4 to 5.5, preferably 4.0 to 4.5.  The low methyl pectin used is one which has not suffered substantial chain degradation in its preparation and 0.8 to 1.8 per cent, calculated on 100 per cent low methyl pectin, is incorporated in the composition.  The methoxyl content of the pectin should be within the range 3-6 per cent, preferably 5 per cent, based on 100 per cent calcium pectate. Additives to the composition are as follows: as buffer salts, tri- or disodium citrate, tripotassium citrate, trisodium phosphate, potassium tartrate, sodium acetate, sodium lactate, sodium pyrophosphate, or monosodium citrate; as flavouring constituents, fruit juice, comminuted fruit, true fruit esters, fruit concentrates, or savoury flavourings; as sweetening agents, sucrose, glucose, sorbitol, or sugar containing compounds.  Unit packs of the composition contain 200-400 ml., preferably 250-350 ml., and may take the form of frozen packs or vacuum sealed cans containing sterilized composition.  Table jellies are made by mixing at 10-30 DEG  C. the liquid composition with fresh, skim, reconstituted dried, diluted evaporated, or condensed milk and to this end one unit pack of composition may be added to one pint of milk.

Filed: 1938-07-20
Abstract: 516,098. Moulding pipes. TURNER & NEWALL, Ltd. July 20, 1938, No. 21594. Convention date, July 20, 1937. [Class 87 (ii)] An integral end socket is formed on an asbestos cement pipe, before the cement sets, by enlarging the diameter at the end by radial pressure while the pipe rotates. The pipe is removed from the moulding mandrel and mounted on a rotating tube 2 held between a lathe chuck 3 and a head 4. The interior of the socket is supported by wedge-shaped plates 8 moving in slots in a drum and expanded outwards by a cone 9 as the socket is formed. Pressure is applied externally by rollers 16, 18 adjustably mounted on a frame 19 which is longitudinally adjustable by a rack and pinion device 20. The cone 9 is carried on a sleeve 11 which is moved over an axial rod 12 by a handwheel 10. The plates 8 may be provided with an annular rubber sheath 14. The socket is formed by rotating the pipe within the rollers 16, 18, expanding the plates 8 internally'and axially compressing the pipe by a collar 30 moved on the tube 2 by a fork 29, wire 28 and windlass device 27. Alternatively, the pipe may be disposed vertically and axially compressed under its own weight.

Abstract: 136,909. Farnsworth, F. C. Dec. 24, 1918. Feed-water, supplying and controlling.-A steam-trap of the counterbalanced receiver type adapted also for gravity boiler feeding, has the receiver adapted to turn on a bearing arranged between the swivelling water and steam connexions. The receiver 2, which is divided by a partition 3 to form a water chamber 4, and a counter-balance chamber 5 adapted to be filled with sand or water through a closable aperture 42 secured to a spindle 11 by a water inlet and an outlet pipe 7 and a steam inlet and venting pipe 6 screwed to the spindle and afterward welded to the tank. The spindle is mounted in a journal 15, provided with lining 14 and adjustably screwed to a base-plate by bolts 13 passing through elongated slots. The ends of the spindle are enlarged to form shoulders 11<a> and are furnished with angled passages connecting the pipes 6, 7 to swivelling connexions 26, 19 mounted on fixed pipes 28, 21. The pipe 21 is connected on the one hand through a non-return valve with the water supply, and on the other through a non- return valve with the water discharge. The pipe 28 is connected alternatively to the atmosphere or a steam supply through a three-way 31 actuated by the tilting of the receiver acting through an arm 33 and link 34. The movements of the receiver are limited by stops 17, 18<a>, of which the stop 18a may be fitted with a dash-pot to lessen the shock when the full receiver tilts. When used to return the water to the boiler, the apparatus is situated sufficiently high above the boiler to allow the water to be delivered into the generator by gravity, a second similar apparatus being employed, if necessary, to raise the water into the upper receiver.

Title: Process for the production of solid salts of the higher molecular alkyl sulphuric acids
Filed: 1930-07-18
Abstract: Solid salts of alkyl sulphuric esters containing more than nine carbon atoms in the molecule, which may be used as emulsifying agents, are prepared by neutralizing the free esters, without any intermediate treatment with water or alcohol, with solid, liquid or gaseous inorganic or organic bases, or their salts with weak acids, in the absence of water or alcohol.  The sulphuric esters may be prepared by sulphonating, possibly in the presence of inert solvents, aliphatic unsaturated hydrocarbons or alcohols containing more than nine carbon atoms, or derivatives which still contain a hydroxy group or a double bond, e.g. unsaturated fatty acids or esters or amides thereof.  Preferably sulphonating agents which do not produce water are employed.  In examples: (1) stearyl alcohol is sulphonated with chlorsulphonic acid in the presence of trichlorethylene and neutralized by passing in gaseous ammonia. The product solidifies and is freed from solvent by expression and drying; (2) ricinoleic acid is similarly sulphonated, in the presence of ether, and is then neutralized with calcined soda.  By recrystallization, e.g. from absolute alcohol, inorganic salts are removed from the product.ALSO:Solid salts of alkyl sulphuric esters containing more than nine carbon atoms in the molecule are prepared by neutralizing the free esters, without any intermediate treatment with water or alcohol, with solid, liquid or gaseous inorganic or organic bases, or their salts with weak acids, in the absence of water or alcohol.

As illustrated the yarn 12 may be bulked by passage through a fluid jet 18 before passage through finish applying device 30 formed by yarn passage 42 and frusto-conical entrance and exit portions 44 (Fig. 3). The liquid finish composition is fed at a metered rate from reservoir 31 to applicator 30 by pump 33 and inlet conduit 32.
