Abstract: Steroid compounds are degraded by conducting the treatment described in Specification 589,282 of the steroid starting material with a carboxylic acid imide, amide or arylamide halogenated at the nitrogen while exposing the reactants to light. The elimination of hydrogen halide may be brought about by heating.  In examples: (1) D 23-3-acetoxy-5-chloro-24 : 24-diphenyl cholene is treated with bromosuccinimide while exposed to light and heated to produce D 5 : 20 : 23 - 3 - acetoxy - 24 : 24 diphenylcholatriene.  After hydrolysis and oxidation of the 3-acetoxy group the side chain is degraded by means of chromium trioxide to produce progesterone; (2) crude D 5 : 20 : 23-3-oxy : 24 : 24-diphenyl-cholatriene obtained in example (1) are purified by crystallization and oxidized as in (1); (3) D 5 : 20 : 23-3-acetoxy-5-chloro-24 : 24-diphenyl-cholatriene obtained in (1) is purified, oxidized with chromium trioxide and saponified with caustic potash to produce D 5 - pregnene - 3 - ol - 20 - one; (4) D 23-3a  : 12b -diacetoxy-24 : 24-diphenyl cholene is treated with bromosuccinimide while exposed to light and the product heated with potassium carbonate to produce D 20 : 23 - 3a  - oxy - 12b -acetoxy-24 : 24-diphenyl-choladiene which may be oxidized directly with chromic acid to 12-acetoxy-pregnane-3 : 20-dione; (5) D 23-3a  : 12b -diacetoxy-24 : 24-diphenyl cholene is treated with bromosuccinimide while exposed to light to produce D 23-3a  : 12b -diacetoxy-22-bromo-24 : 24-diphenyl cholene which may be isolated and on heating gives D 20 : 23-3a  : - 12b  - diacetoxy - 24 : 24 - diphenyl - choladiene which may be hydrolysed to D 20 : 23-3a  : 12b -24 : 24-diphenyl choladiene.  The diene-diacetate may be oxidized to produce 3a  - oxy - 12b  - acetoxy - pregnane - 20 - one.  Other starting materials, e.g. D 23-3a -12b -di-acetoxy-24 : 24-dimethyl-cholene or D 5 : 20-3b -acetoxy-cholestadiene can be used to obtain the same product; (6) D 23-3a  : 12b -diacetoxy-24 : 24-diphenyl-cholene is converted to D 20 : 23 - 3a  : 12b  - diacetoxy - 24 : 24-diphenyl using bromophthalimide, which is hydrolysed to the diene-monoacetate and oxidized to 12-acetoxy-pregnane-3 : 20-dione; (7) D 23-3-acetoxy-5-chloro-24 : 24-diphenyl-cholene is converted to D 20 : 23-3-acetoxy-5-chloro-24 : 24-diphenyl-choladiene using bromosuccinimide which is oxidized with chromic acid to 3-acetoxy-5-chloro-pregnane-20-one; (8) as in (7) using bromophthalimide instead of bromosuccinimide; (9) the following compounds are degraded as in (5); D 23-3b -acetoxy-24 : 24-diphenyl-allocholene, D 23-3a  : Fa  : 12b -triacetoxy-24 : 24-diphenyl cholene and D 23-24 : 24-diphenyl-allocholene.  Samples have been furnished under Sect. 2 (5) of (1) progesterone obtained from D 20 : 23-3-acetoxy-5-chloro-24 : 24-diphenyl-choladiene (obtained in Ex. 7) and (2) 5-chloro-pregnane-3 : 20-dione obtained from 3-acetoxy-5-chloro-pregnane-20-one (obtained in Ex. 7).

Title: Process for obtaining crepe effects on fabrics
Filed: 1931-04-09
Abstract: Cellulose carboxylates; cellulose acetate, dyeing; textiles, treating with liquids.--Fabrics showing crepe effects are obtained by weaving in highly twisted cellulose acetate threads in which are incorporated substances having high affinity for water and thereafter treating the fabrics with water.  Specified substances are calcium chloride, calcium nitrate and sodium lactate.  The water used in the final step may contain any substance of which the action on the fabric constitutes a step in the manufacture, e.g. a dye or a substance for removing the dressing.  In an example cellulose acetate threads of 75 deniers with 24 individual threads are used for the warp of a fabric at 51 threads per cm., the weft consisting of similar cellulose acetate threads containing 10 per cent of sodium lactate at 30 threads per cm. and having twists, alternately left and right, of 2800 turns per metre.  After weaving the fabric is treated in a bath of pure water at 85 DEG  C. to obtain a crepe-de-chine effect.
Patent GB-877400-A (GB)
Title: Improvements in and relating to boiler plant
IPC: F23N1/02
Filed: 1960-03-24
Abstract: 877,400. Automatic control systems for boilers. CROOK, C. March 24, 1960, No. 10561/60. Class 38 (4). [Also in Group XII] The solid fuel feed to a boiler furnace is controlled in accordance with the flue gas or combustion air flow, and the flue gas or air flow is controlled by the steam pressure or water temperature and by the means controlling the fuel feed so that the fuel/air ratio and steam pressure or water temperature remain constant. The fuel feed rate is adjusted by altering the intervals during which a stoker motor 3 is running. A cam 40 running at a constant slow speed engages a contact 36 on a lever 30 to energize a relay 52 and close contacts 48, 50 in the stoker motor circuit, and a hold contact 64 by-passing the cam circuit. The relay 52 remains closed, and the stoker motor runs until a second cam 68 on the same shaft as cam 40 opens a contact 60. A tail piece 70 on the cam 40 lifts the lever 30 so that a rack 34, Fig. 3, on its underside is freed from a pawl 28. The pawl 28 is carried by an arm 20 secured to a balance bar 17 connected to two floats 12, 14. The interiors of the floats are connected one to either side of a restrictor in the flue, so that a change in the flue gas flow causes a change in the pressure difference between the floats, thus moving the balance bar 17 and pawl 28 and adjusting lever 30 to vary the fuel feed period. A mercury switch 114 mounted on a plate 80 connects the supply line 116 to either conductor 108 or 110 to drive a motor 104 to close or open respectively a damper 5 in the flue. The switch plate 80 is free of the casing and pivoted to a link 82 depending from the balance bar 17 and a lever 76 responsive to variations in steam pressure. An increase in steam pressure moves the lever 76 and switch plate 80 anticlockwise so that the switch 114 starts the motor 104 to close the flue damper 5. The decrease in gas flow in the flue moves the balance bar 17, shown in its position for no gas flow in an anticlockwise direction, so that link 82 restores the switch plate 80 to a horizontal position and switches off the damper motor. The damper motor 104 can only be energized when the relay 52 is energized, that is when the stoker motor is running. The double float arrangement may be replaced by a single float arrangement as described in Specification 737,383, or by a diaphragm device. The float or diaphragm arrangement may be responsive to the flow of combustion air into the furnace, and the steam pressure-responsive device may be replaced by a device responsive to water temperature.

Title: Improvements in or relating to Dynamo Electric Machines.
IPC: H02K9/00
Filed: 1917-07-23
Abstract: 125,673. Vickers, Ltd., and Barclay, S. F. July 23, 1917. Armatures and field magnets, cooling; cores.-Relates to the cooling of dynamo-electric machines, particularly high - speed alternators, and consists in employing two separate air currents, one passing axially through the rotor, the other passing radially, and preferably in axial direction also, through the stator. The radial and axial ducts in the stator communicate through openings of varying size so as to give the required air distribution. Fig. 1 is a partial section through the axis of machine, and Fig. 2 is a part transverse section. The air for cooling the rotor enters at one end of the machine through an inlet 17, and is drawn through the chamber 30 beneath the rotor end connexions 7, along the axial ducts 24 beneath the rotor conductors 6, below the opposite end connexions 7 and through the fan 25 to the outlet 27. Additional ducts 34, Fig. 2, may be formed in the rotor core to carry air and also to regulate the magnetic density. The stator is built up of annular laminations 3 which are separated in the axial direction by radial strips 12, thus forming radial passages for the air current. Axial ducts 14 are also formed through the stator, and the continuity of these ducts is maintained by incomplete rings 15. The gaps 16 in these rings are on the side remote from the machine axis, and afford communication between the axial ducts 14 and the radial ducts 11. The rings 15 may be secured to radial strips similar to the strips 12. The gaps 16 are preferably larger near the centre of the stator. The air current for the stator is drawn in at each end through inlets 17, 18 by fan blades 19, 20 and passes along the air gap and outwards through the radial passages 11. The air also passes over the end connexions 10, and through the axial ducts 14 towards the centre of the machine, gradually escaping through the gaps 16 into the radial passages, and finally emerging through openings 22 in the casing. Covers may be placed over the ends of the axial ducts 14 to regulate the air flow. The fan 20 may be arranged to give a stronger current than the fan 19 in order to compensate for the inequality in the cooling of the rotor due to the air entering it at one end and leaving it at the other. This may alternatively be compensated by differently shaping the passages 29, 32. External fans may be used instead of mounting the fans on the rotor core.
