Patent GB-831277-A (GB)
Title: Gravity operated conveyors and feeding installations for granular materials
Inventor: LUCAS DOUGLAS HAROLD
IPC: B65D88/70
Filed: 1956-09-04
Abstract: 831,277. Pneumatic conveyers; hoppers. CENTRAL ELECTRICITY GENERATING BOARD, and LUCAS, D. H. L. Dec. 4, 1957 [Sept. 4, 1956], No. 27078/56. Class 78 (1).  The flow of granular materials, e.g. small coal, from a main storage bunker 30 into a subsidiary bunker 65 and its discharge therefrom, is stimulated by the intermittent admission of compressed air through one or more rotating nozzles 68, 32 at points where the flow may be impeded. Each nozzle consists of an outer tube 40, to which compressed air is supplied through a tee 41, and an inner tube 42 slidably mounted therein. An aperture 39 is provided in the tube 42 adjacent its closed end 43 and the other end is secured by welding to the forked end 44 of a rod 45 which is slidably mounted in a bush 46 inserted in one end of the tee. A bearing plate 47 is mounted on the bush and forms an abutment for a compression spring 49. The spring bears also on a plate 48 attached to the end of the rod 45. A twisted bar 53 of square section is attached to the rod 45 and passes through a square hole 54 in a U-shaped stirrup 55, the ends 56 of which are pressed hard against the plate 47 by a compression spring 58. When a blast of air is admitted through the tee, the pressure of the air on the plate 43 will cause the tube 42 to move to the left and the movement of the bar 53 through the hole 54 will cause it to rotate since the rotation of the stirrup 55 is prevented by friction. When the air supply is cut off, the spring 49 returns the tube to its retracted position and since the friction between the twist 53 and the stirrup is now less, the stirrup will turn through a small angle and carry the tube 42 with it.

Title: Improvements in and relating to the removal of sheets from a pile
IPC: B65B43/14
Filed: 1927-10-18
Abstract: 279,831. Miller, J. C. Oct. 26, 1926, [Convention date]. Sheet-separators; pile supports. - Sheets are separated from the bottom of a pile A by a reciprocating serrated rubber block 4 carried by a lever 5 pivoted to a reciprocationg slide 7, and while the separator acts to move the bottom sheet of the pile the upper part A' of the pile is lifted from the bottom part A<2> by cam-shaped rubber lifters 32 on shafts 26 oscillating by eccentric-and-lever mechanism. The shafts 26 are also fitted with adjustable spring plates 33 which grip the side edges of the sheets while the separator is acting, and which are set so as to grip all the sheets above the bottom one and so tend to prevent double feed. Should double feed occur, the top sheet is kept back by a reversely rotating roller 38 driven faster than the main driven roller 37 which normally advances the separated sheets to the main feed rollers 40, 41. The roller 38 is mounted in an adjustable lever 42. The. slide 7 is reciprocated by an adjustable rod 12 operated by an oscillating lever 14 operated by a cam 17. There is an adjustable lost-motion device between the. rod 12 and the slide 7, so that there is a dwell in the motion of the separator 4 at each end of its stroke. During these dwell periods the lever 5 is operated by a collar 21 on rod 12 acting on a cam-lever 24 carried by the slide 7, and the separator 4 is thus caused to engage the bottom sheet, or permitted to move out of contact with the pile by the action of a spring 44.

Abstract: 953,869. Two-part couplings; preventing access of moisture, dust and gases; carrying cables through partitions. PLESSEY CO. Ltd. Aug. 8, 1960 [Aug. 14, 1959], No. 27825/59. Heading H2E. In a seal in which wires or contact elements extend through holes 5 in a bung 4 of elastomer material e.g. a silicone elastomer, the bung is adhesively secured in an aperture of greater size, in a rigid housing 1, so as to be tensionally prestressed before the insertion of the wires or contact elements. The bung may be moulded in the housing 1 between flanges 2 and 3 after the appropriate surfaces of the housing have been treated with a suitable liquid primer. The shrinkage inherent in the moulding and curing operation produces tensional stress in the bung, thus affording it an increased yielding capacity to accommodate the expansion of holes 5 when contact elements are inserted. Alternatively the bung may be secured in position by applying adhesive to the appropriate surfaces and then expanding the bung by axial compression until the adhesive sets, thus leaving the bung under tensional stress when the compression is removed.

Title: Improved cellulosic product and method of improving the spinning step in the production of regenerated cellulose by the viscose process
IPC: D01F2/08
Filed: 1949-11-01
Abstract: Raw cotton, particularly cotton linters, is rendered specially suitable for conversion into rayon by incorporating 0.01-0.2 per cent by weight, based on the dry weight of the cotton, of a cation-active amino compound selected from the following: an alkyl amine having 7-18 carbon atoms, an alkyl alkanolamine having at least one alkyl radical with 8-14 carbon atoms and having 14-18 total carbon atoms, a lauryl ether of an alkanolamine, lauryl piperidine, lauryl methyl cyclohexylamine, an acylated ethylene or polyethylene polyamine with an acyl radical of 7-18 carbon atoms or an amidine derived from such a polyamine, an acylated hydroxyethyl ethylene or polyethylene polyamine in which the acyl radical has 7-18 carbon atoms. an alkyl imidazoline having an alkyl radical with 7-18 carbon atoms, and an alkyl guanidine having an alkyl radical with 7-18 carbon atoms.  If desired, the addition may be made during the production of alkali-cellulose but prior to completion of the shreding thereof. The treated cellulose may be used in the production of cellulose esters or ethers, and artificial fibres, films, and sheets.  If desired, there may also be incorporated in the cotton cellulose a minor proportion, e.g. 0.02-0.05 per cent, of a mixed ether having attached to the ether oxygen a polyethylene oxide radical and an aliphatic hydrocarbon radical having 7-18 carbon atoms.  The treated cellulose is particularly suitable for use in the production of viscose and regenerated cellulose fibres from viscose.  Impregnation of the cellulose is preferably carried out by use of an aqueous solution or dispersion of the compound, e.g. in the form of a soluble salt such as the acetate.  The added compound improves the emulsifying action of anion-active compounds commonly used in the viscose process with oily delustring agents. Specified cation-active amino compounds which may be used include heptyl, octyl, (2-ethyl) hexyl, decyl, lauryl, tetradecyl, hexadecyl, oleyl, and octadecyl amines; methyl and dimethyl lauryl amines; lauryl ether of triethanolamine; monoamides of hydroxyethyl ethylene diamine and oleic, stearic, and lauric acids; mixtures of mono-and di-amides of tetraethylene pentamine and fatty acids from coconut oil and mixtures of amides of diethylene triamine and mixed caprylic and capric acids; the oleic acid amide of diethyl ethylene diamine; 2-undecyl imidazoline, and 2-heptadecyl-N-acetamidoethyl imidazoline; lauryl guanidine. The cation-active amino compounds may if desired be used in admixture with minor proportions of anion-active substances such as fatty or resinic acid soaps.  Specifications 590,064 and 685,843 are referred to.
