Patent GB-468972-A (GB)
Title: Improvements relating to the removal and recovery of carbon dioxide from gases
IPC: C01B32/50
Filed: 1936-01-20
Abstract: Dipiperidyls or their homologues are prepared by the reduction of the corresponding dipyridyls or by the electrolytic reduction in acid solution of the corresponding pyridine bases, e.g. by the electrolytic reduction in acid solution of technical pyridine bases. They may be freed from froth-producing impurities by blowing with air at 70--75 DEG  C. followed by distillation.ALSO:Acidic gases, such as carbon dioxide, sulphur dioxide and hydrogen sulphide, are recovered from gas mixtures by a cyclic process in which the gas is brought into contact with one or more dipiperidyls or their homologues in the presence of water, the compound formed is decomposed to regenerate the absorbent and liberate the acidic gas and the absorbent so regenerated is re-used.  Preferably the dipiperidyls &c. are used in aqueous solution.  If the acidic gas is carbon dioxide or hydrogen sulphide the solution may be regenerated by simple heating.  In the case of sulphur dioxide, water should be added at intervals during the heating to prevent charring.  The absorbents may be prepared by the electrolytic reduction of the corresponding pyridine bases, e.g. by the electrolytic reduction in acid solution of technical pyridine bases.  They may also be prepared by the reduction of the corresponding dipyridyls.  Preferably the crude dipiperidyls prior to use are freed from froth-producing impurities by blowing with air at 70--75 DEG  C. followed by distillation.

Title: Improvements in or relating to a governor control for a fuel system of a gas turbinepower-producing plant
Inventor: DAKIN ROBIN MICHAEL
IPC: F02C9/16
Filed: 1963-01-16
Abstract: 1,042,251. Gas turbine engine fuel systems. BRISTOL SIDDELEY ENGINES Ltd. Jan. 13, 1964 [Jan. 16, 1963], No. 1930/63. Heading FIG. [Also in Division G3] A governor control for a gas turbine engine fuel supply system comprises a valve 6 the Fig. (not shown), pivoted at 5, controlling the leak from a passage 8 to position a servo piston (not shown) of a rotary fuel pump. The arm 4 of the valve 6 is positioned by pressures acting on diaphragms 11, 12, 20 and 21. The pressure acting on diaphragm 11 is a pressure proportional to the speed of the engine and acts in opposition to a speed datum pressure acting on diaphragm 12 which is adjusted by a device 15 as described in Specification 1,013,135. The pressure acting on diaphragm 20 is direct feed back pressure being the fuel pressure fed through conduit 26, throttles 25, 27, chamber 24 and conduit 23. The pressure acting in a chamber 30 on the diaphragm is a delayed action feed back pressure supplied through throttle 25 and a flow restrictor bank 31 and exhausted through a flow restrictor bank 33. The chamber 30 is also bounded by a spring loaded diaphragm 35 which is connected to a spring loaded diaphragm 40. The diaphragm 40 is subjected to pressure in a chamber 39 supplied from the fuel pump through conduit 47 and restrictor 48. Leakage from the chamber 39 is controlled by a valve 46 connected to large diaphragms 49, 50, subjected to datum speed pressure and actual speed pressure respectively, and smaller diaphragms 52, 53 subjected to actual speed pressure and the pressure in chamber 44 connected to the chamber 39. If the speed of the engine rises suddenly, the valve 6 is opened by the pressure acting on diaphragm 11. The pressures acting on diaphragms 49, 50 also open valve 46 to reduced the pressure in chamber 39 and the diaphragm 35, 40 move to the right to reduce the pressure in chamber 30 thus causing the valve 6 to open further to provide a quick action to reduce the fuel supply. The throttle banks 31, 33 then allow the pressure in chamber 30 to rise to a steady lower level. If the engine speed suddenly falls, the reverse occurs, the diaphragms 35, 40 moving to the left to increase the pressure in the chamber 30 rapidly.

Abstract: 328,225. Humphrey, F. J. Jan. 21. 1929. Coiling; reeling.-In a machine for armouring cables or other flexible cores by coiling flexible metallic strip, formed by rolls i n t o interlocking shape, on a core fed through a hollow rotating mandrel, and then compressing it on the core, the reel or reels carrying the core are connected to the mandrel through a clutch so as to control the rate at which the core is rotated and thus to maintain it at the correct twist relatively to the laying-on and compressing of the armouring in spite of variations in the hardness of the strip. The strip is drawn through forming dies or rollers to impart thereto an interlocking shape by a drum 38 which is driven by gearing 43, 42, 40, 39 from the shaft 15. The hollow shaft 11 which carries a hollow mandrel 16 with a reduced end 17 is driven from the shaft 15 by gearing 12, 13. The carrier 21 for the reels 22 of core material is mounted on a shaft 18 rotated by chain gears 47, 46 from the shaft 11 through a clutch 49 controlled by a pedal 50. The armoured cable is drawn by a winding drum 25 first between a pair of adjustable soft pads 55 for removing excess oil and for exerting a preliminary compression on the armouring and then through a tapered helically grooved die 37 for compressing the armouring upon the core. The die may be replaced by a series of stationary grooved tapered rollers 59, Fig. 5, arranged in stepped formation longitudinally so that each roller overlaps one of the other rollers for about half its length to effect a progressive compression of the armouring. Each roller is rotatably mounted in a bracket 61 adjustable radially by a screw 63 in a bearing 62 which is carried by a slidable rod 64 held in adjusted position by a screw 67. The winding drum 25 is mounted in a carrier 26 rotated by chain gear 29, the drum being rotated through a. friction coupling by bevel gear 35, 34 and spur gear 31, 30 from the shaft 28.
