Title: An improved process for annealing alloys
IPC: C22F1/02
Filed: 1932-05-31
Abstract: 404,292. Annealing. GENERAL ELECTRIC CO., Ltd., Magnet House, Kingsway, London, and CAPLAN, M. C., c/o. General Electric Co., Wembley, Middlesex. May 31, 1932, No. 15447. [Class 72.] In the bright annealing of alloys containing one or more constitutients which are volatile at the annealing temperature, e.g., brass, the alloy is annealed in a non-oxidising atmosphere in a substantially gas - tight externally heated chamber, the same charge of gas being maintained within the chamber at least as long as the temperature of the alloy is such that an appreciable loss of the volatile constituent therefrom would otherwise occur. The non- oxidising gas used is commercial hydrogen deprived of its oxygen and water vapour by purifying agents. The alloy is contained in a pot 1 heated by resistances 9, and tubes 7, 5 provided with taps serve for the entry and exit of the hydrogen. The pot is filled with the material to be treated, and in the case of wire the material occupies as much as 15 per cent of the total volume of the pot, and the lid 2 sealed tight. The air in the pot is removed by passing purified hydrogen through the pot, pipes 7 and 5 both being open. The tap on pipe 5 is then closed and the pot is then heated to the annealing temperature, 650‹ C. for brass, and maintained at that temperature for a suitable period, the tap on the pipe 7 remaining open, so that the hydrogen supply is in communication with the pot throughout the annealing. The pot is then cooled and then the tap on the pipe 7 is closed and the pot opened. The tube 3 contains a pyrometer.

Title: Process for the manufacture of new dyestuffs
IPC: C09B47/06
Filed: 1937-06-03
Abstract: Phthalocyanine dyes are made by heating copper salts with phthalic acid-4-sulphonaamides in the presence of urea, if desired with the addition of compounds of elements of Group V such as molybdates, vanadates, and phosphates or with the addition of boric acid, or by heating cuprous cyanide with 1 : 2-dihalogenbenzene-4-sulphonamides in the presence of tertiary amines.  They show bluish to greenishblue shades.  In so far as they still contain hydrogen atoms attached to the nitrogen of the sulphonamide group they may be transformed into colour lakes, e.g. by causing them to react with alkaline earth metal salts.  In examples: (1) 1 : 2-dibrombenzene-4-sulphophenylamide is boiled with cuprous cyanide in quinoline; the phthalocyanine tetraphenylsulphonamide obtained is soluble in aqueous alkalies; (2) phthalic acid-4-sulphonamide is heated with urea, cuprous chloride, boric acid and ammonium molybdate; the soluble dyestuff may be precipitated with barium chloride; (3) similar to (2) using phthalic acid-4-phenylsulphonamide and copper chloride; (4) phthalic acid-4-methylphenylsulphonamide is treated as in (2); (5) and (6) similar to (3) using phthalic acid-4-n-butyl or 4-isobutylsulphonamide; the products are soluble in aqueous caustic soda, pyridine, dioxane and acetone.  Specifications 464,126, 464,673, and 476,243 are referred to.  The phthalic acid sulphonamides are made by treating phthalic acid sulphochloride with ammonia or amines.

Title: Improvements in or relating to a device for guiding roll film onto a reel for development
IPC: G03D13/14
Filed: 1944-08-14
Abstract: 588,188. -Developing photographic films. KODAK, Ltd., and GYATT, C. E. Aug. 14, 1944, No. 15480. [Class 98 (ii)] A roll film container having pivotal movement about a support has an elongated film guide fixed to it near a film slot in the container so that the film may be guided in its passage from the container to a processing reel of the kind in which the turns of the film are spaced apart by causing its edges to engage in spiral tracks formed in the reel flanges. As shown, a stand 7, 8 supports pivotally at 6 a film container 1 having an end - disc removable for loading, a stubspindle 5 on which a film roll is mounted, and a guide roller 13 adjacent to a film delivery slot 12. Fixed to the container near the slot is an elongated slotted film guide 10 with channelled edges 11 and a tapered lower end 16 which extends between the flanges of a processing reel 19 detachably mounted on the stand 7 on a spindle provided with a handle 29. After securing the leading end of the film between a pin 28 and the core of the reel, rotation of the handle 29 causes the film to be drawn from the container 1 along the guide 10, the end 16 of which feeds it to the reel 19 where its edges enter the spiral tracks in the flanges by reason of a slight transverse curvature imparted to the film by the guide 10. The pivoting of the container allows the guide 10 to swing as the diameter of the winding on the reel increases. The apparatus may be used also for rewinding the processed film from the reel 19 on to a spool replacing the container 1 and fitted with a crank handle. A magazine such as that described in Specification 563,308 may be placed in the container 1 for transfer of its film to the reel 19.

Title: Improvements in and relating to temperature regulators
IPC: G05D23/24
Filed: 1926-06-22
Abstract: 253,948. British Thomson-Houston Co., Ltd., (Assignees of Hull, A. W.). June 22, 1925, [Convention date]. Vapour and vacuum or low-pressure apparatus, arrangements of.-The temperature of an electrically heated device, e.g. a resistance furnace, is kept constant by means of a resistance responsive to temperature which varies the polarity of an electromotive force applied to the input circuit of an electron discharge device, the varying current in the output circuit being employed to control the temperature. A furnace 10 is heated by a resistance 11 supplied from mains 12, and controlled by a switch 13 which may short-circuit a section 11<a> of the resistance. The electromagnet 14 which operates the switch 13 is controlled by a device operated by variations in the resistance 20, having a positive temperature coefficient, due to temperature variations in the furnace. A Wheatstone bridge 15 is connected to an alternating current supply 21, one of its resistances being the resistance 20. An electron discharge device 16 has its filament 24 connected to an alternating current supply through a transformer 24<a>, while the grid 25 is connected to a step-up transformer 29 so as to be responsive to the voltage across the terminals 27, 28 of the bridge. The filament is connected to a point 32 in the resistance 18, so that the grid has a negative bias. The plate 26 is connected through the magnet coil 14 to the point 23 and thence to the supply source 21. When the furnace is slightly above the predetermined temperature, the potential of 27 will be negative relatively to 28 when the point 23 and plate 26 are positive. The transformer 29 then applies a negative potential to the grid, which reduces the plate current to such a value that the magnet 14 releases the switch 13 and allows it to open. The consequent insertion of the resistance 11<a> reduces the heating in the furnace. If the furnace falls below the required temperature, the potential of 27 becomes positive relatively to 28, producing a positive potential on the grid, and an increase in plate current which closes the switch 13 and short-circuits the resistance 11<a>. The temperature of the furnace may be controlled within Œ0.1‹ C. In a modification, two stages of amplification are used, each stage consisting of a push-pull circuit, and in another modification a mercury vapour rectifier is used for controlling the supply of current to the furnace, in combination with a Wheatstone bridge, with or without a thermionic valve amplifier.

Title: Improvements connected with the indication or control of the performance of synchronous dynamo electric machines
IPC: H02P9/14
Filed: 1940-10-25
Abstract: 544,920. Control of A.C. motors. BARRACLOUGH, E., and MOSSAY, P. A. H. Oct. 25, 1940, No. 15708. [Class 38 (iii)] [Also in Group XXXVI] The phase angle between the axis of the secondary winding of, a synchronous dynamoelectric machine and the axis of the flux that cuts it is continuously measured or recorded by. means of the angular displacement or the torque reaction of the casing of an auxiliary synchronous machine. The synchronous motor 1 under test is mechanically coupled to a smaller auxiliary synchronous motor 2 which. is wound for the same synchronous speed, has the same number of poles, and is connected to the same source of supply. The motor 1 is fixed on a base plate 3, its shaft 4 being mounted in standards 5 and coupled to the shaft 9 of the motor 2 by a coupling 11. The casing 6 of the motor 2 is mounted on trunnions 7 in bearing standards 8 so as to be independently rotatable about its shaft 9, which is mounted in bearing standards 10. If the motors 1, 2 are running on no load the casing 6 of the motor 2 takes up a definite position with respect to the casing of the motor 1 when load is applied to the motor 1, the casing 6 deviates from this position by an angle approximately equal to the phase angle of the motor 1, and this angular displacement is a measure of the load on the motor 1. In a modification, rotation of the casing 6 is prevented and the reaction of the casing is measured and serves as a measure of the load on the motor 1. In another construction the motors 1, 2 are coupled through a differential gear, the load being indicated either by . the angular motion or torque reaction of the planet carrier. Gearing may be introduced between the motors 1, 2 so as to allow them to be constructed for different speeds. The angular displacement of the reactive effort of the motor 2 may serve also or alternatively as a governing factor in the regulation of the performance of the motor 1.
