Title: Arrangement of heating surfaces in tubular boilers having forced circulation of the working medium and a shaft type of combustion chamber
IPC: F22B29/06
Filed: 1932-12-10
Abstract: 398,068. Water-tube steam boilers. SIEMENS-SCHUCKERTWERKE AKT.- GES., Siemensstadt, Berlin. Dec. 10, 1932, No. 35091. Convention date, Dec. 10, 1931. [Class 123 (ii).] In a forced circulation steam generator comprising a number of parallel connected tubes forming a band winding in the form of a helix and lining a combustion chamber, the band is divided into a series of sections by a series of collecting and distributing headers to which the respective ends of the sections are connected. The water to be evaporated is driven by pump 1 through the preheater a and enters the boiler proper through pipe 4 connected to header 5. It then flows in succession through the tube sections 6, 10, 14, 18 to the top header 19, passing from thence by tube 20 to the bottom header 21 and then rising through sections 22, 26, 30 to header 31, from which it passes by tube 32 to the superheater c. In the construction shown in Fig. 3, the tubes instead of being divided into two parts by a tube 20, as in Fig. 1, are divided into six parts by tubes 58, 62, 66, 70, 74. The tubes may be divided into as many parts as desired. The headers may be protected from the furnace gases by plates or by leading the heating tubes in front of them, as shown in Fig. 7.

Title: Winding apparatus
Inventor: TOWNSHEND KENNETH NAPIER
IPC: H01F41/06
Filed: 1963-09-05
Abstract: 1,022,069. Winding cable; traverse mechanism. STANDARD TELEPHONES & CABLES LTD. Sept. 5, 1963, No. 35121/63. Heading D1J. The cable 1 is traversed onto the drum 2 by a traverse guide 5 on a screw-threaded shaft 6, the shaft 6 being driven by an electromagnetic clutch 8 interposed between the shaft 6 and reciprocable connecting rod 11, the reciprocable rod 11 activating the shaft 6 during one direction of its stroke, there being clutch control means for selecting the direction of the stroke during which the connecting rod is coupled by the clutch 8 to the shaft 6. The connecting rod 11 is reciprocated by a rotating cam 13 driven by gearing 14 and activating a changeover-switch 16 during each half revolution thereof such that the clutch 8 is only energized during every upward stroke of the connecting rod 11. The traverse guide 5 then moves to the right in a series of steps until it strikes a limit switch 20 activating a further change-over-switch 17. The resulting new setting of the switch 17 causes the rotating cam 13 to actuate the change-over-switch 16 such that the clutch 8 is only energized during each downward stroke of the connecting rod 11. The traverse guide 5 then moves to the left in a series of steps until it strikes a further limit switch 19 that causes the change-over-switch 17 to revert to its original setting. The distance between the limit switches 19 and 20 may be adjustable to vary the length of traverse. The connecting rod 11 has a pivotal connection 10 at its upper end that is adjustable in a slot 18 to vary the angular rotation of the screw-threaded shaft 6 per connecting rod stroke.

Abstract: 392,113. Wired wireless systems ; impedance networks. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Rives, F. M. ; 1475, Keyes Avenue, Schenectady, New York, U.S.A.) Dec. 13, 1932, No. 35343. Convention date, Dec. 18, 1931. [Classes 40 (iii) and 40 (v).] A tuned circuit, suitable for coupling a carrier-wave signalling system 1 to a line-wire 2, is designed to transfer any one or all of a number of different signalling frequencies. The two sides of the coupling network are symmetrical. The condensers 3 and inductance 4 are tuned to one working frequency, and a network 5 is inserted to accommodate the other frequencies. For instance the condenser 6 and inductance 7 are made resonant with 3, 4. These are then shunted by a condenser 8 or other reactance which, together with the coupling, condenser 3 and inductance 4, is made resonant to a second working frequency. In the same way a third frequency is accommodated by inserting a series circuit 9, 10 in tune with the second frequency and shunting it with a reactance 11, such that the circuit 3, 8, 11, 4 is resonant to the third frequency.

Title: Improvements in or relating to methods of treating latex
IPC: C08C1/02
Filed: 1936-12-28
Abstract: A stable sterilized latex or like dispersion is produced by maintaining the pH of the dispersion substantially unchanged for an appreciable period of time by the addition of a suitable buffer solution, and sterilizing the dispersion by heat treatment during such period.  The buffer solution preferably has the same pH as the fresh latex itself and for Hevea latex of pH7 a suitable buffer solution is a neutral solution of M/20 mono-basic potassium phosphate containing the requisite amount of M/20 sodium hydroxide solution to bring the pH to 7. 250cc. of this buffer solution may be added to 1000 cc. of fresh Hevea latex. Sterilization can be effected by heating to temperatures above 100 DEG  C. by steam under pressure. The latex may be concentrated prior to or after the addition of the buffer reagents, or the buffer reagents may be added to serum from latex and the mixture used to dilute concentrated latex.

Filed: 1934-12-13
Abstract: A carboxylic amide group is introduced into organic compounds containing at least four condensed nuclei by reacting such compounds with carbamyl chloride or its alkyl substitution products in the presence of a catalyst of the Friedel-Craft type. The carbamyl chlorides may be taken as such or in the form of their stable compounds with catalysts of the Friedel-Craft type (cf. Specification 449,100); reagents which yield carbamyl chloride, e.g. potassium cyanate and anhydrous hydrogen chloride, may also be used.  Specified polynuclear compounds are pyrene, chrysene, perylene, fluoranthene, triphenylene, naphthanthracene and brasane and their halogen, alkyl, aryl or aralkyl substitution products, and also naphthofluorene, isochrysofluorene, naphthacene, 1 : 2-benzoanthracene, and picene. The reaction may be effected at a raised temperature in a solvent or diluent, a number of which are specified.  The amides obtained may be saponified to yield the corresponding acids.  In the examples: (1) pyrene and methylcarbamyl chloride in the presence of aluminium chloride yield pyrene-3-carboxylic acid methylamide, from which the acid is obtainable by alkaline saponification; if methylcarbamyl chloride is replaced by potassium cyanate and dry hydrogen chloride is led into the mixture, pyrene-3-carboxylic amide is obtained; amides are obtainable similarly from 3-chloropyrene, 3- or 4-methylpyrene, perylene, naphthofluorene, isochrysofluorene, naphthacene and picene; (2) chrysene and methylcarbamyl chloride, brought to reaction as in example 1, yield a chrysene carboxylic acid methylamide; (3) fluoranthene and carbamyl chloride in the presence of aluminium chloride yield a fluoranthene carboxylic amide, from which the corresponding acid is obtainable by saponification; (4) a triphenylene carboxylic amide is prepared as in example 3, and may be saponified to yield the corresponding acid; (5) a brasane carboxylic amide is prepared as in example 3. Other specified catalysts are iron chloride and boron fluoride.
