Title: Improvements in or relating to gas treating devices for enclosed electrical apparatus
IPC: H01F27/14
Filed: 1927-06-30
Abstract: 296,160. Ellis, A. G., Metropolitan- Vickers Electrical Co., Ltd., and Diggle, H. June 30, 1927. Drying air and gases.-The air or gas admitted to the space above the oil in the casing of an oil-immersed electrical transformer is dried and/or deoxidized by passage over the surfaces of desiccants such as calcium chloride or deoxidizing agents such as ground copper and ammonium chloride or phosphorus disposed in horizontal layers in a chamber communicating with the casing. The desiccant &c. is carried in perforate segmental trays 14 mounted upon a rod 10 and supported by a spring 17 in the cylindrical chamber 1 which communicates through a tube 5 and a lateral passage 2 with the transformer casing 6 and the air or gas inlet and relief valves 4, 3 respectively. The lower end of the rod carries a pointer 12 which indicates through a gauge glass 8 the degree of saturation of the desiccant &c. When the pressure in the transformer falls owing to a fall in temperature, air or gas flows through the valve 4 into the cham. ber 1 and over the surfaces of the trays to the casing 6, while a rise in pressure due to a rise in temperature effects the opening of the relief valve 3. By removing the cover 7 of the chamber the rod and trays can be removed as a unit. In a modification, the trays are supported in a rectangular chamber so as to form channels 29, 30, Fig. 2, the air or gas entering the chamber through a tube 38, Fig. 3, and an oil seal 32 and being constrained to flowover the lower trays 26 in parallel and over the upper trays 25 in series. The lower trays are provided with drain lips 31 and the moisture absorbed by the dessioant flows into the seal 32 and is automatically discharged through a syphon 37. Specification 241,547 is referred to.

Abstract: 542,862. Lathes. ETCHELLS & SON, Ltd., D., and ETCHELLS, D. R. Dec. 19, 1940, No. 17914. [Class 83 (iii)] In a machine for performing a pointing or like operation on a shank of a bolt or like headed article, the bolt 10, Fig. 1, is gripped with its head pointing outwardly and pointed by a rotary tool 11, the head of the bolt being engaged by outwardly-biased ejector means whereby when the grip on the bolt is released the bolt is ejectd. The machine shown is duplex, one of the bolts 10 being pointed while a bolt is inserted at the other station. The bolts are gripped between a lower notched jaw 12 and a movable upper notched jaw 13. A motor 17 drives a shaft 18 connected by gearing 21 to a hollow shaft 22 having limited longitudinal movement in bearings 23, 24 and carrying the pointing tool 11. The shaft 18 is also geared to a cam shaft 32 carrying for each unit cams 33, 34. The cam 34 acts through a lever 36 and push rod 42 on the upper jaw 13 which is forced upwardly by springs 43. The cam 33 acts through a pivoted lever 49 to impart axial movement to spindle 22 to effect the pointing operation. A link 63 connects the lower end of lever 49 to a lever 64 carrying a plate spring 66 terminating in a carrier for an ejector 16 which has a flange engaging behind the head of the pin. The spring 66 is tensioned during the forward movement of the tool spindle so that when the grip of the upper jaw is released the spring impels the ejector forward and ejects the pin 10 forward clear of the machine.

Abstract: <PICT:0689497/III/1> Spray-drying is effected by spraying the liquid into a downwardly-flowing stream of hot gases at a temperature not higher than 750 DEG F, and introducing into the resulting mixture, at a level below the spraying-device, hot combustion gases having a temperature higher than 1000 DEG F.  The gas stream of lower temperature is obtained by diluting a portion of the hot combustion gases with cooler gases.  Drying chamber 1 is provided with a spraying-device 6 comprising a liquid inlet pipe 6a, a vaned wheel 8 driven by an electric motor 7, mounted in cylinder 5 and surrounded by a duct 10 which contains directing-vanes 11. Furnace 14, which comprises a brick-lined cylinder provided at the base with gas-burners 19 and an air-inlet 20, is connected to chamber 1 at two different levels by ducts 21 and 13.  Duct 21 is below the level of spray wheel 8, while duct 13 communicates with gas-flue 12, which opens into duct 10.  An inlet 25 for supplying secondary air or a portion of the exhaust gases, into the furnace, is provided above duct 21.  All the pipes leading into or out of the furnace are provided with dampers.  Hydrocarbon gas or other fuel is burned in burners 19 with air introduced through inlet 20. A portion of the resulting hot gases, preferably at a temperature of about 1500 DEG F, is introduced into the drying-chamber through duct 21.  The remainder of the hot gases is cooled to 750 DEG F or below by diluting gas introduced through inlet 25, and the mixture is introduced into the top of the drying-chamber via duct 13, where it forms a rotating gas blanket into which the liquid to be dried is sprayed by wheel 8.  The gases containing the dried material are exhausted from the base of the drying-chamber at a temperature of about 230 DEG F, by means of a fan connected to a pipe 15 via cyclone separators (not shown).
