Abstract: 543,297. Linear polyamides. DU PONT DE NEMOURS & CO., E. 1. July 8, 1940, No. 11363. Convention date, July 6, 1939, [Class 2 (iii)] Linear polymers are prepared by heating a polyamide-forming composition comprising, as essential' re-acting material, one or more compounds each containing two, and only two, amide-forming groups, these groups being carboxyl, isocyanate or isothiocyanate groups, the compound or the proportions of the compounds being such that there are present substantially chemically equivalent quantities of the complementary amide-forming groups. Thus, the polyamide-forming composition may comprise a dicarboxylic acid and a diisocyanate or a diisothiocyanate, or may consist of an isocyano- or an isothiocyano-monocarboxylic acid. The re-action may be continued until the polymer is capable of being formed into fibres. Examples are given. Specified starting materials are : dicarboxylic acids -adipic, glutaric, sebacic, dihydromuconic, carbonic, oxalic, malonic, succinic, pimelic, suberic, azelaic, decane-1:10-dicarboxylic, methyl malonic, #- methyl adipic, maleic, itaconic, acetylene dicarboxylic, cyclopentane-1:2-dicarboxylic, cyclopentane-1:3-dicarboxylic, cyclohexane-1:2- dicarboxylic, cyclohexane-1:3-dicarboxylic, cyclohexane-1:4-dicarboxylic, phthalic, isophthalic, terephthalic, diphenic, naphthalene- 1:2-dicarboxylic, naphthalene- 1:3-dicarboxylic, naphthalene-1:4-dicarboxylic, naphthalene-1:5-dicarboxylic, diphenylene-2:21- dicarboxylic, . diphenylene-4:4<SP>1</SP>-dicarboxylic, diphenylene-2:41-dicarboxylic, xylylene-1:4- dicarboxylic, xylylene-1:3-dicarboxylic, xylylene-1:2-dicarboxylic; and dicarboxylic acids containing hetero-atoms such as HOOC (CH 2 ) 3 S(CH 2 ) 3 COOH. diisocyanates and the corresponding diisothiocy nates of ethylene, trimethylene, tetramethylene, hexamethylene; decamethylene, propylene-1:2; butylene-1:2, butylene-1:3, butylene-2:3, . ethylidene, propylidene-1:1, propylidene-2:2, cyclopentylene-1:3, cyclohexylene-1:2, cyclohexylene-1:3, cyclohexylene-1:4, cyclopentylidene, cyclohexylidene, xylylene-1:4, xylylene-1:3, and hetero-atom diisocyanates such as OCN (CH 2 ) 3 O(CH 2 ) 3 NCO. isocyano-monocarboxylic acids : 6-isocyanocaproic acid, 10-isocyanodecanoic acid, 3- (isocyanomethyl) . benzoic acid, 4-(isocyanomethyl) alpha-naphthalehe carboxylic acid, and the corresponding isothiocyano-mono-carboxylic acids. Interpolyamides may be prepared by using mixtures of re-actants, e.g., two dicarboxylic acids and two diisocyanaters. Amide interpolymers may be obtained by including with the re-actants, bifunctional reactants of other types, such as hydroxyacids or glycols. Viscosity-stabilized polymers can be prepared by adding one reactant slightly in excess of the chemically equivalent amount. Specification 461,236 and U.S.A.

Title: Improvements in Feed Systems for Cigarettes or other Rod-like Articles
IPC: A24C5/352
Filed: 1967-03-15
Abstract: 1,174,612. Cigarette packaging apparatus; endless conveyers. HAUNI-WERKE KORBER & CO. K.G. 15 March, 1967 [18 April, 1966], No. 12062/67. Headings B8A and B8C. A storage arrangement sited between cigarette or like making machinery and packaging apparatus, comprises means for filling open sided trays from the making machines and emptying the trays to supply the packaging apparatus, the trays moving in a vertically disposed rectilinear closed path between the emptying position and a position for distribution to one or more filling points. Filling.-In the described arrangement, two cigarette making machines feed cigarettes to two identical tray filling devices (2), 4, see also Figs. 1, 2 (not shown), each of which includes a known form of suction head (28) which lifts cigarettes off a supply belt (32) and forms them into batches. A pusher (34) thrusts a line of batches into a corresponding line of cells 36 in a tray, the tray being supported to be moved downwards intermittently by a drum 40 having slots engaging the cell walls, to present each cell line for filling. When the tray is filled, its support platform 44 swings downwards and backwards to deposit it on a surface 54, at the same time pushing a preceding filled tray 38 on to a conveyer 58. Emptying.-The conveyer 58 moves the tray on to the lower run 10 of the closed track leading to the emptying position where it joins others being advanced by a pusher 66. Filled trays are also fed to this position from the device (2). The leading tray is raised in steps, initially by a platform and then by a drum similar to the drum 40, to present each line of cells to pushers 84 which discharge the blocks of cigarettes into pockets 100 of a conveyer 98 taking them to a wrapping station. At the latter, pusher pushers 107 feed the blocks to a wrapping wheel 104 (not detailed). When the tray is empty and at the top of its travel, a pusher 114 places it on belts 130, 132 carrying it to an upper distributing position where a chain conveyer 136 feeds it to either filling device 2 or 4, according to demand. The apparatus is controlled throughout by switches operated by the trays and tray conveying means.

Abstract: 1374064 Treating exhaust gas W R GRACE & CO 13 March 1973 [31 May 1972] 12070/73 Heading F1B I.C. engine exhaust system catalytic converter comprises a chamber through which exhaust gas flows and which contains a catalyst system comprising at least two monolithic sections, each section having passages for the flow of substantially parallel and linear streams of exhaust gas therethrough and having a catalyst on the passage surfaces, the sections being mounted one after the other within the chamber and having between each two successive sections means for inducing turbulence in the gas flow between the sections. The convertor comprises a housing 17 containing a monolithic ceramic catalyst support 30, having passages 18 to 22 on which a thin film of the catalyst is deposited. The support is in three sections separated by gaps 23 and 24. The flow of gas through the'passages.is laminar and the gaps 23 and 24 which are 0À5 to 5 cms wide create turbulence which gives better contact of the gas with the succeeding sections. The pre-  ferred support material is alpha alumina. Other suitable materials are sillimanite, mullite, magnesium silicates, iron, petalite, spodumene, cordierite or aluminasilicates. In an example, the support which was 3À0 ins long and 4À0 ins diameter was coated by dipping one end into platinum sulphide solution and the other end into palladium nitrate solution, drying at 250‹F and calcining for 3 hours at 1000‹F. The preferred thickness of the coating is 0À0004-0À001 in. The surface area of the film is at least 50 sq m/gm and preferably 100 sq m/gm. The carrier has a surface area less than 10 sq m/gm and may be less than 1 sq m/gm. The monolithic support provides 5-200 sq ins (preferably 10-80 sq ins) of superficial surface area per cu in of engine displacement. Air, which may be heated, can be provided in the proportion of 3%-50% of the exhaust gas volume.
