Abstract: 607,024. Automatic control systems. MACDONALD, J. P. A., and FOLKESTONE GAS & COKE CO. May 24, 1946, No. 15886. [Class 38 (iv)] The calorific value of a town gas supply is controlled by a recording calorimeter adapted to operate - a photo-electric cell which intermittently controls a valve byepassing the exhauster for a diluent gas such as carburetted water gas, blue water gas, or producer gas which is mixed with coal gas. The pen arm 2 of the recording calorimeter carries a mirror 6 which reflects light from a lamp 3 through a slit 7 with an adjustable shutter 9 on to a photo-cell 8, controlling a two-position relay 10. The relay controls two magnet-valves 26, 28 which connect a floating bell 19 having a mercury seal 20, either to the gas pressure main or to a vent to atmosphere or the exhauster intake, whereby the bell is caused to move, and adjust the byepass valve 22. Alternatively, the bell may operate the exhauster steam valve to vary the speed. The supply for the lamp, relay and magnet valves is energized to perform this adjustment for ten seconds every five minutes by any suitable means such as a motor 15 driving a cam-operated switch 14 through a reduction gear 16. The range of movement of the bell in each ten-second period may be preset by a throttle valve 32.

IPC: H02K3/24
Filed: 1954-06-01
Abstract: 765,110. Cooling dynamo-electric machines. GENERAL ELECTRIC CO., Ltd. May 25, 1955 [June 1, 1954], No. 16237/54. Class 35. In a machine such as an alternator, one fan circulates coolant through the stator and rotor and a second fan assists the first in causing the medium to flow through the rotor, both fans being driven by the rotor. As shown in Fig. 1, fan 7 draws hydrogen from coolers 4 and passes it into stator and rotor passages, the flow through the rotor by hollow conductors or over solid conductors being augmented by fan 8 which discharges it into annular passages 11 for conduction back to the coolers. The space between the stator core and casing is subdivided into axial ducts with the gas flowing in opposite directions in adjacent ducts, e.g. some gas from fan 7 flowing to the left then radially inwards through stator ducts, then radially outwards through other stator core ducts to the passages 10 which return it to the cooler. To enable the rotor end windings to be cooled by relatively cool gas, some of the gas from fan 7 passes over the right-hand end windings as shown in Fig. 6 and is then passed through unwound axial passages in the rotor to the end windings at the other end. The hydrogen pressure may be of the order of 15-45 lb. per square inch. Figs. 8-10 (not shown) describe end winding cooling arrangements. Specifications 720,521 and 777,468 are referred to.

Patent GB-572017-A (GB)
Title: Improvements relating to coating and impregnating compositions
IPC: C09D101/14
Filed: 1943-10-04
Abstract: A coating or impregnating composition comprises a volatile solvent, a mixed ester of cellulose (which contains radicals of acetic acid, at least 0.3 radicals of a mono-carboxylic acid of at least 6 carbon atoms, and not more than 0.2 hydroxy groups per glucose unit of the cellulose ester molecule) and a mineral pigment or metallic powder content of 25-70 per cent based on the weight of the cellulose ester, but the composition contains no plasticizers for the cellulose ester. The composition is suitable as an aircraft fabric dope but may be used for other purposes, e.g. impregnating or coating fabrics, particularly woven fabrics of cotton, linen, or high-tenacity regenerated cellulose, or wood or metal.  When applied to a textile fabric which is stretched over a frame as in an aircraft fabric component, the fabric is kept in a tautened condition and given a smooth, weather-resistant surface.  The higher carboxylic acid radical of the cellulose mixed ester may be the radical of stearic or other fatty acid containing 12-18 carbon atoms.  The liquid vehicle of the dope preferably comprises a low-boiling solvent, and a medium-boiling solvent, i.e. of boiling point within the range of 130-170 DEG  C.  For a cellulose acetate-stearate solution, ethyl acetate, acetone, methyl acetate, or methyl ethyl ketone, may be used as low-boiling solvent.  Ethyl lactate, cyclohexanone, diacetone alcohol, butyl acetate, or mono-methyl or ethyl ether of ethylene glycol may be used as medium-boiling solvent or diluent. Benzene and xylene also may be used as diluents.  Several coatings may be applied and the outer layers may contain a higher proportion of pigment or metal powder.  Substances which absorb ultra-violet radiation may be incorporated in the solutions, e.g. salol, Michler's ketone, fluoranthene, or benzal acetophenone. Cellulose acetate-palmitates or acetate-laurates may be used instead of cellulose acetate-stearates.
