Title: Improvements in fire extinguishing systems
IPC: A62C3/08
Filed: 1938-12-12
Abstract: 522,530. Fire - extinguishing ; valves. AMERICAN - LAFRANCE - FOAMITE CORPORATION. Dec. 12, 1938, No. 36232. Convention date, Dec. 11, 1937. [Class 47 (ii)] [Also in Group XXIX] In a fire-extinguishing system, particularly for aircraft. a source of compressed gas is connected to more than one point of danger through a selector valve, a single manual control member serving, through two distinct operations, both to operate the valve and to cause discharge of gas from the source. As shown, a cylinder 1 of carbon-dioxide, having a cutter operable by mechanism in a head 2, is connected by a pipe 5 to a valve 6 from which extend pipes 7, 8 leading to the engine compartments and a ,pipe 9 leading to a safety vent. The head 2, Fig. 9, comprises a wedge member 35 adapted to be moved by a cable 32 so as to operate a lever 38 which bears directly on the cutter 4. The pipe 9 leads to a vent 10, Fig. 8, arranged beneath the fuselage and fitted with diaphragms 12, 13 adapted to rupture in the event of a serious leakage of gas from the cylinder, so as to permit safe escape of the gas to the atmosphere and to provide an indication of such escape. The .selector valve comprises a body 6, Fig. 5, a cover 14 which, with the body, provides a valve chamber, and a non-metallic valve disc 17 carried by a stem 18. The disc 17 has. a port 24 adapted to register with any one of the passages 7 - 9, and a slot or recess 23 which co-operates with a nipple 22 of the pipe 5 in order to restrict the movements of the disc. The valve is fitted with an index plate 28, Fig. 7, with indicia corresponding to the pipes 7-9, and the stem 18 has a pointer 29 which also serves as a handle. A further handle 30 slidable on the squared end of the stem is connected to the cable 32, so that a pull on the handle 30 serves to actuate the cutter 4. A catch 40, however, prevents axial movement of the handle 30 until the stem has been turned to a position in which the valve disc will pass gas to one of the danger points 7 or 8. In the inoperative position of the. apparatus, the valve disc connects the pipes 5 and 9, and the handle 30 cannot be moved to actuate the cutter.

An upper jaw 45 is fixed to a piston rod 38 of an air cylinder 37 mounted on an arm 36 of a post 35. The jaw 45 is tapered in cross-section and has a layer 46, Fig. 5, of plastic material covered with flexible sheets 47, 48. A heating element 50 in the form of a continuous ribbon is disposed between the sheets 47 and 48. A narrow splicing jaw 55 is positioned in the table 20, the upper surface of the jaw being covered with a layer 56 of plastic material covered with a sheet 57 enclosing an air space 60. In operation, the end portion of a length 62 (Fig. 2, not shown) of cloth is placed on a row of pins 61 and pressed downwardly into engagement with the jaw 55, Fig. 5. A length of bonding film 66, Fig. 1, is then drawn from a roll 65 across the width of the length of cloth. The film 66 is a thermosetting resinous material that becomes soft and tacky on heating and rapidly cures to become a non-tacky solid. The end portion of a length 62<SP>1</SP> (Fig. 2, not shown) is placed on pins 62<SP>1</SP> and pressed downwardly into engagement with the film 66. The table 20, Fig. 1, is then raised to splicing position by the lever 28, such that the jaws 45 and 55, Fig. 5, engage, thereby closing a microswitch, not shown. The microswitch actuates a timing device, not shown, such that current is supplied to the heating element 50. After a delay sufficient for the element 50 to attain working temperature, air is supplied to the cylinder 37, Fig. 1, to press the jaw 45 downwardly. After a further delay sufficient to permit bonding of the cloth by the film, the element 50 is deenergized and the supply of air to the cylinder 37 is turned off. The hand lever 28 is actuated to lower the table 20 to permit removal of the spliced lengths of cloth.

Title: Improvements in or relating to nuclear reactors
Inventor: CARLSON WALTER BERNDT
IPC: G21C3/16
Filed: 1959-10-29
Abstract: 893,742. Nuclear fuel elements. BABCOCK & WILCOX Ltd. Oct. 24, 1960 [Oct. 29, 1959], No. 36712/59. Class 39(4) A ceramic nuclear fuel pellet in the form of a right circular cylinder comprises a plurality of sectors at least partially divided from one another. Such a pellet is shown in cross-section in Fig. 2 and comprises three sectors 4 separated from one another by narrow gaps 6 which progressively increase in width towards the centre of the pellet. The dimensions of the gaps 6 are sufficient just to accommodate the thermal expansion of the adjacent sectors or, alternatively, are slightly-greater than this so as to provide reservoirs for gaseous fission products. The end faces 8 of the pellet are of concave form in order to accommodate the differential axial thermal expansion of the pellet. Alternatively as shown in Fig. 3, the gaps 16 between the sectors 14 do not extend as far as the periphery of the pellet, the portions 18 of adjacent sector faces being radial so that assembly of the sectors to form pellets housed within a sheath is facilitated. In a further embodiment (Fig. 6), a pellet comprises three sectors 34 pratially divided from one another by surface groovings 36 on one or both end faces of the pellet. In the latter case, the groovings on one face are directly opposed to those on the other face. On being subjected to thermal stresses, the pellet tends to break into sectors. Additionally, the surface groovings provide space for the accommodation of gaseous fission products.

Title: Alkylation of aromatic amines
IPC: C07C209/18
Filed: 1954-12-22
Abstract: Nuclearly alkylated aromatic amines are prepared by heating aromatic amines having at least one hydrogen atom attached to the nitrogen atom and at least one hydrogen atom attached to the aromatic nucleus, with an olefine at a temperature of 200-400 DEG  C. in the presence of aluminium.  Aromatic amines may be aniline, the toluidines, xylidines, naphthylamines and their substitution products.  Olefines may be ethylene, propylene, butylene, iso-butylene and their higher homologues or cycloaliphatic olefines such as cyclohexene or aromatic olefines such as styrene. The aluminium catalyst may be in the form of metallic aluminium, aluminium alloy, an aluminium compound which decomposes under the reaction conditions to form metallic aluminium such as aluminium triethyl, or a mixture of aluminium and a metal compound which decomposes to give an aluminium alloy such as aluminium and mercuric chloride.  The alkylation is carried out by heating the aromatic amine with the aluminium catalyst at alkylation temperature until the evolution of hydrogen has ceased so as to form the N-aluminium derivative of the amine, and then adding the olefine. With gaseous olefines, sufficient olefine is introduced to the reaction vessel to give a pressure of 50-300 atmospheres and the mixture is allowed to react at alkylation temperature until the required quantity of olefine has been absorbed.  In continuous operation, the aromatic amine and catalyst may be pumped through a heated pressure tube with the olefine.  The reaction product is isolated by steam distillation and/or vacuum distillation.  Both mono- and di-alkylated aromatic amines may be obtained.  In examples: (1) aniline, granulated aluminium and mercuric chloride, are heated under pressure with ethylene to yield 2:6 - diethylaniline; (2) 2 - methylaniline, aluminium powder and mercuric chloride are heated with ethylene to give 2-methyl-6-ethyl aniline; (3) aniline, aluminium chips and mercuric chloride are heated with propylene to give a mixture of 2-methyl-6-ethyl aniline and 2:6-diisopropyl aniline; (4) 3-methyl aniline, aluminium powder and mercuric chloride are heated with ethylene to give 3-methyl2:6-diethyl aniline; (5) 4-methyl aniline, aluminium and mercuric chloride with ethylene give 2:6-diethyl-4-methyl aniline; (6) 3:5-dimethyl aniline, aluminium powder and ethylene give 3:5-dimethyl-2:6-diethyl aniline; (7) asym-m-xylidine, aluminium powder and ethylene give 6-ethyl-2:4-dimethyl aniline; (8) illustrates preparation of mixtures of 2-ethyl aniline and 2:6-diethylaniline using various proportions of ethylene; (9) diphenylamine, aniline, aluminium and mercuric chloride with ethylene give a mixture of 2:6-diethylaniline and 2:21-diethyl-diphenylamine.  Acetyl derivatives of 3-methyl-2:6-diethyl aniline, 2:6-diethyl-4-methyl aniline, 3:5-dimethyl-2:6-diethyl aniline, 6-ethyl-2:4-dimethyl aniline and 2-ethyl aniline and the benzoyl derivative of 2-ethyl aniline are mentioned.
