Title: Improvements in and relating to the indirect generation of steam by means of superheated heating steam
IPC: F22B1/14
Filed: 1929-02-15
Abstract: 306,098. Schmidt'sche Heissdampf- Ges. Feb. 15, 1928, [Convention date]. Heating by indirect contact of steam.-In a steam generator 2, Fig. 1, heated by steam passed alternately through superheating coils 8 and immersed heating coils 9, the heating steam is the working steam from the generation or from a separate boiler, the steam being taken from the last heating coil to an engine or heatexchanger. Steam from the generator 2 is led through a superheating coil 21. The superheating coils may be placed in the combustion chamber of a return-tube boiler 1. The exhaust steam from a compound engine 23, 24 driven by high pressure steam from the generator is taken into the pipe 11 supplying steam from the return-tube boiler to the engine 26, 27. At starting up, water is supplied to the first superheating coil 8 by a branch 14 to generate steam, and the last heating coil is connected by a branch 15 to a condenser. Water is supplied to generator from the boilers by a pump 19. In a modification, the superheating elements are arranged as walls around the combustion chamber of an externally fired multitubular boiler. In another modification, the superheating elements are placed in the firebox and flue tube of a boiler of the locomotive type. The heating steam may be taken from the indirectly heated generator 2, Fig. 4, itself, and the superheating elements 52 may be placed around the walls and at the bottom of a separate combustion chamber 48, from which the gases pass downwardly over superheating and feed heating coils 55, 62, 64. The whole of the steam from the generator 2 may be taken through the superheating elements and the heating coils and finally superheated in the flues of a fired boiler, and part of this steam may be allowed to pass into the boiler water.

Patent GB-669099-A (GB)
Title: A control valve or metering device
IPC: F25D11/02
Filed: 1949-02-25
Abstract: In a distillation system wherein distillate collects in a container 41, Fig. 7, the <PICT:0669099/III/1> <PICT:0669099/III/2> removal of non-condensible gases contaminating the distilled vapour is controlled by a valve 411 subjected to the partial pressure of these gases.  The gases plus some uncondensed vapour passing the valve enter a rectifier 40 wherein the vapour condenses and the gases pass into a chamber 43 containing a float supported by the condensate and operating a valve.  The gases depress the liquid level in the rectifier 40 and the chamber 43 to open the float valve and pass into a pipe 42 leading to atmosphere or to other condensers operating at lower temperatures whereby a number of fractions may be collected from the distillate.  The valve 411 comprises a vessel 419, Fig. 8, movable relatively to pipes 417, 418 respectively leading to and from the rectifier, and supported by a sealed bellows 426 containing a small quantity of distillate.  Condensate from the rectifier overflows the vessel 419 and returns to the container 41 via a pipe 416.  The condensate retained in the valve body 412 wets the exterior of the bellows whereby the vapour pressures on the inside and outside thereof are equal, and the vessel closes the pipe 417.  The partial pressure of any non-condensible gas therefore moves the vessel to uncover the end of the pipe 417 to admit the gas to the rectifier.

Title: Improvements in the elimination of cellulose ester fibres from mixed textile materials containing wool
IPC: D01C5/00
Filed: 1945-03-05
Abstract: Wool is recovered from mixed textile materials containing wool and cellulose organic ester fibres by immersing the materials in an aqueous bath containing a saponifying agent for the cellulose ester and an inorganic salt which inhibits the destructive action of the saponifying agent on the wool, until the cellulose ester fibres have been converted into regenerated cellulose fibres and then carbonizing the cellulose fibres in the treated material. The saponifying agent may be sodium, potassium or ammonium hydroxide, sodium carbonate, sodium silicate, methylamine, ethylene diamine or triethanolamine. Sodium hydroxide of 0.1 to 1 per cent strength may be used.  The inhibiting salt may be sodium sulphide or sodium chloride.  The treatment may be effected at 10-50 DEG  C.  Carbonizing may be effected by treating the textile material with sulphuric acid, hydrochloric acid, or aluminium chloride, or other carbonizing agent in solution or vapour form, and then after a preliminary drying if necessary, subjecting the textile material to a baking operation. After baking the dried material is shaken, neutralized, rinsed and dried.  The mixed textile material may be subjected to a treatment to remove or lighten any colour effect prior to being subjected to the saponification treatment, e.g. it may be treated with sodium hydrosulphite solution.  The textile material may be in the form of waste fibres or in the form of a fabric, e.g. a fabric containing wool and cellulose acetate fibres with or without cellulose fibres. Decorative effects may be obtained by weaving a fabric of wool and cellulose acetate fibres and then removing all of the non-woollen material.

Title: Improvements in wire and like spooling machines
IPC: B65H59/38
Filed: 1940-04-02
Abstract: 542,957. Winding wire &c. LLOYD, H. J., and RICHARDS, S. H. April 2, 1940, No. 5919. [Class 120 (ii)] The speed of rotation of the spool of a wire or like spooling machine is varied during spooling so that the wire is wound at a constant tension by driving the spool-carrying shaft through a differential gear comprising a member rotated at a constant speed, a second member coupled to the spoolcarrying shaft, and a third member fast with a fly wheel having an angular momentum substantially equal to that of the spool when fully wound at the speed of winding. As shown the members of the gear are in axial alignment, a gear 2 on the shaft carrying the spool 6 engaging gears 1a in the casing 1 driven by a pulley 8 at a constant speed and the gears 1a engaging a gear 3 on the shaft of the fly wheel 7. The tendency to increase of tension in the wire as the spool 6 increases in diameter results in a momentary reduction of speed with a corresponding acceleration of the fly wheel which slows down the spool and maintains a constant tension in the wire.
