Patent GB-183261-A (GB)
Title: Improvements in or relating to the generation and superheating of steam
IPC: F22B1/12
Filed: 1921-04-21
Abstract: 183,261. Lamplough, F. April 21, 1921. Superheating by steam. - Steam is generated by the heat of exhaust steam heated by furnace gases, and the steam generated is superheated in tubes placed inside the tubes in which the exhaust is heated. The feed-water is preheated by the heated exhaust, and means are provided to relieve excess pressure at the feed inlet. Exhaust from an engine 2 is passed in turn through a number of parallel furnace heated tubes 6, and then through drums 14, 16 opening into the condenser 18. Feedwater flows through coils 34, 32 in the drum and is converted into steam, which is superheated in U-tubes 22 arranged in the heated tubes 6.

Title: Apparatus for forming or dressing the operative faces of grinding wheels
IPC: B24B53/08
Filed: 1939-04-18
Abstract: 527,654. Trueing grinding wheels. COVENTRY GAUGE & TOOL CO., Ltd., HARLEY, S. J., and WAINWRIGHT, J. E. April 18, 1939, No. 11662. [Class 60] In a machine for forming helical serrations on a grinding wheel a adapted for grinding screw threads or toothed gears the depth feed and longitudinal motions of the dressing tool b are correlated with each other and with the rotary motion of the grinding wheel in such a way that variation in the speed of any motion produces automatic corrective variations in the others. The tool b is fed longitudinally by a spindle f operated by a lead screw o and transversely by a screw e which carries the tool and is operated by a cam h on a spindle k driven through gears m, n from a splined shaft l. A spiral gear u, driven in any suitable manner, is connected through gear s, shaft r, and spiral gears t, w, to the spindle of the grinding wheel and carries a'sun wheel q of a differential gear, the other sun wheel p of which is connected to the shaft l driving the cam h. The planet carrier x is driven independently of the wheel u by a shaft v and is connected by gears 1, 2 to the lead screw, If in operation rotation of the shaft v is stopped, the tool will not be traversed but will be fed transversely by the cam h and produce a transverse section on the rotating grinding wheel. Also the speed of the transverse feed by cam h is increased or decreased relatively to the speed of revolution of the grinding wheel in accordance with the lead screw feed produced by rotation of the carrier x. The splined shaft l may be locked by a clamp y so that the wheel may be preliminarily formed by a tool operating without depth feed.

Abstract: 541,578. Valves. BRITISH THOMSON-HOUSTON CO., Ltd. July 15, 1940, No. 11706. Convention date, July 14, 1939. [Class 135] A valve of resilient material having a central clamping portion 15 connected to a rim portion 16 by radial arms 17 has a guard plate 20 having a similar shape, the face of the rim 45 of the guard facing the valve member being of wavy formation and the arms 22 thereof being curved so that in operation when the rim 16 of the valve lifts and becomes distorted in shape it is uniformly stressed. When raised the portion of the rim 16 midway between a pair of arms 17 first contacts the guard plate, the areas in contact then increasing until the whole area of the valve member is in contact with the guard plate. By this means noise is minimised. The device as shown is applied to an air compressor, the guard 20 being only applied to the discharge valves 12. The latter and the inlet valve 11 are clamped to a valve plate 10 by a screw 21. The clamping face of the screwhead 38 has a flat portion 43 and curved or coned part 44. The face 40 of the guard 20 may be shaped in like manner.

Title: Improvements in or relating to the manufacture of concentrated gas liquor
IPC: C10K1/00
Filed: 1937-05-03
Abstract: In the manufacture of concentrated gas liquor by the process described in the parent Specification, the quantity and temperature of the ammoniacal condensate leaving the condenser are controlled so that the steam and ammonia are not cooled and absorbed completely, these unabsorbed vapours being <PICT:0494023/III/1> then subjected to scrubbing with a limited quantity of gas liquor so as to form concentrated gas liquor, e.g. containing 15-20 per cent of ammonia. Gas liquor is fed through line 1 and heat-exchanger 2, where it is heated by hot gas liquor from the decarbonating section 6 of an ammonia still 14, to line 3 and preheater 4 where it is further heated by vapours from the head of the ammonia still.  The preheated feed then passes to the decarbonating section 6 where steam is admitted, whereby part of the carbon dioxide and hydrogen sulphide and part of the ammonia are expelled through a line 7 to a scrubber 8 in which the ammonia is absorbed by cool gas liquor, while the carbon dioxide and hydrogen sulphide pass off through line 9 for sulphur removal with iron oxide.  The fortified scrubbing liquor issuing through line 10 is collected in a tank 26, whence it may be fed to line 1.  The decarbonated gas liquor from the decarbonating section 6 passes through line 11 and the heat-exchanger 2 and thence by line 50 to the water-cooler 12.  The cooled liquor is fed by line 13 to the ammonia still proper 14, where it is distilled with steam, the still-head temperature controlling, through a relay 15 of the type described in Specification 116,074, [Class 69 (ii)], the valve 17 regulating the supply of gas liquor and the valve 18 regulating the supply of steam to the decarbonating section.  The hot ammoniacal vapours pass from line 16 through the preheater 4, the line 19, and the water-cooled condensers 20, 21, emerging at a temperature of 40-50 DEG  C. so that all the ammonia is not absorbed in the steam that is condensed, a mixture of ammonia, carbon dioxide, hydrogen sulphide and some steam passing by line 22 to a water-cooled scrubber 23 fed with ordinary cold gas liquor so as to form a concentrated product containing 15-20 per cent of ammonia, which collects in tank 26.  The final traces of ammonia are absorbed by cold gas liquor in a scrubber 24.  A second embodiment is described for treating "unfavourable" gas liquors, i.e. those in which the ratio (NH2 - H2S) /CO2 is 1/1,6 or more.
