Title: Improvements in the activation of carbonaceous materials by gases
IPC: C01B32/336
Filed: 1930-07-24
Abstract: <PICT:0359546/III/1> The method of activating carbonaceous material in alternate phases of internal heating and activation according to the parent Specification is carried out in at least two activation furnaces or retorts, one being at the heating phase while the other is at the activation phase, the furnaces being reversed at intervals and the gases evolved during the activation phase in one furnace being utilized for the heating of the other furnace.  Reversing regenerators and continuous air and gas heating apparatus are provided for utilizing the waste heat.  Two chambers F1, F2 filled with the carbonaceous material to be activated such as wood, vegetable or animal waste, peat, lignite, anthracite, &c., or such substances partly or completely carbonized with or without other chemical substances, are connected at their lower parts by a flue b which conducts the combustible gases leaving the chamber F1 during the activation stage to be burnt with preheated air supplied at p in the chamber F2 to heat the material therein.  The combustion products pass by a pipe e2 to a checker-work regenerator R2, further preheated air being admitted at o2, and through a valve g2 to a steam superheater S, an air heater T and thence to the chimney U.  Steam from the superheater S passes through a pipe i and valve kl into the regenerator R1 where it is raised to a high temperature and passes through a pipe e1 to the top of the furnace F1 and through the carbonaceous material, activating it with the production of the combustible gases which are burnt in the passage b and chamber F2. When the temperature in the furnace F1 has fallen sufficiently, the valves g2, k1, o2 are closed and the valves g1, k2, o1 opened to reverse the furnaces and regenerators.  A gas or oil burner may be provided at a or a supplementary supply of hot gases may be introduced at this point for use in starting up.  The chambers F1, F2 are provided with charging hoppers and discharge doors allowing of continuous or intermittent descent of the material.  Steam is supplied to the superheater by a pipe h.  In a modification, the material to be activated is placed in porous or apertured refractory retort vessels within the chambers F1, F2.  The valves may be interconnected for reversal.

Each block has a central hole d or l for the reception of lifting-appliances, these holes being subsequently plugged. In the form shown in Fig. 4, the blocks are connected together by cement briquettes or dowels j seated in recesses k in the upper peripheral portions, or by rings similarly seated. Alternatively, metal connecting bars or wires passing through the blocks, or seated in grooves formed round the blocks, may be employed.

Title: Improvements in or relating to a narrow fabric loom
IPC: A44B19/34
Filed: 1960-06-27
Abstract: 954,698. Ribbon looms. O. FIRING. June 27,1960 [July 13, 1959], No. 22491/60. Heading D1E The invention concerns a ribbon loom wherein the weft is beaten-up by moving the inserting needle closer to the fell on withdrawal than on insertion. Weft tensioning, needle and needle operation: Figs. 1,2, 5,9,15. The weft F is pressed against a driven supply roll 36 by a roller 37, passes through a coil spring 46 and thence to the inserting needle 14. The needle 14 is mounted on a shaft 16 attached to a bearing 24 which contacts a "wobble" shaft 24 eccentrically mounted on the main shaft 6 so that, as the shaft 6 rotates, the shaft 16 and needle 14 is caused to oscillate to the same extent as the eccentricity of the wobble shaft 24. The shaft 16 is mounted in a bearing 18 forming part of a yoke 19 pivoted on the casing 1. The bearing 18 is attached to a cam 28 which causes the yoke 19 to oscillate and gives the shaft 16 and needle 14 an "up and down" and a "to and fro" motion for the beat-up. Selvedge forming: Figs. 1,3, 15 and 17 to 25, not shown: The main shaft 6 carries a profile cam 34 which oscillates a lever 32 carrying a selvedge needle 31 which is inserted in a groove on the underside of the weft needle 14 to pick up the weft F and knit the edge. Healds, lew and tappet mechanism: Figs. 2, 4. Tappet shafts 8, 11 are driven from the main shaft 6 and carry cams 70, 66 which positively oscillate slides 69, 62 carrying rods 68, 59 having cantilevered heald frames 60, 72, 73. The heald frames 72, 73 carry leno healds 74, 75 which, while shedding, are caused to oscillate by face cams 82 on a gear 80 carried by the main shaft 6 and thus to weave in to the ribbon stuffer warp cords (Figs. 10 to 14, not shown). Ribbon take-up: Fig. 1. The ribbon T is pressed to a breast beam 100 by a roller 57, changes its plane and passes around a roller 57 and is taken up by a driven roller 53 and pressure roller 56.

Title: Lubricating greases
Inventor: PEARSON JAMES WILLIAM
Filed: 1955-08-10
Abstract: A lubricating grease, which is anticorrosive and does not cause bearing wear, comprises a hydrocarbon lubricating oil thickened to a grease consistency with a soap and up to 10 per cent each, based on the weight of the finished lubricating grease, of a nitrite and an ester which has a boiling point above 100 DEG C. and which does not, in the proportion used, itself gel the lubricating oil.  The lubricating oil may be a mineral oil, a polymerized olefin or an alkylated aromatic petroleum fraction. Soaps which may be employed are metal soaps of fatty acids, hydroxy fatty acids, acids produced by the oxidation of petroleum oil and waxes, resin acids (including tall oil acids, abietic acid, dehydroabietic acid and dihydroabietic acid) and naphthenic acids.  Soaps of sodium, potassium, lithium, calcium, barium, zinc, lead, cobalt and aluminium are mentioned, and many examples are given.  Suitable nitrites are inorganic nitrites (e.g. nitrites of sodium, potassium, lithium or calcium), nitrites of amines (e.g. dicyclohexyl ammonium diisopropyl ammonium, decyclammonium and tri-tertiary-butyl ammonium nitrites) and quaternary ammonium nitrites (e.g. trimethyl benzyl ammonium nitrite).  The esters may be esters of mono-, di- or poly-carboxylic acids or of inorganic acids, and among the esters of monocarboxylic acids are mentioned alkyl, benzyl, cyclohexyl and glyceryl esters of aliphatic acids, and in some cases chlorostearic acid, benzoic acid or furoic acid, and fatty oils such as castor oil.  Specified esters of di- and poly-carboxylic acids are di(2-ethylhexyl) or di(3, 5,5-trimethylhexyl) adipate, sebacate or azelate, diethyl, dipropyl or dibutyl adipate, malonate, glutarate, oxalate or tartrate and tributyl, triamyl or trihexyl aconitate or tricarballylate.  Suitable inorganic esters are tributyl or tritolyl phosphate, triphenyl phosphite, dibutyl carbonate, ethyl or butyl xanthate and chloronaphtha xanthate.  The lubricating grease may also contain water, ethylene glycol, glycerol, antioxidants such as phenyl alpha - or beta - naphthylamine, ds(4-aminophenyl) phenylmethane or di(4-dimethylaminophenyl) methane, and extreme pressure agents. In the examples, lithium hydroxystearate greases are prepared by saponification of hydrogenated castor oil with lithium hydroxide monohydrate in the presence of mineral lubricating oil and sodium nitrite, phenyl alpha-naphthaylamine and castor oil (or tritolyl phosphate, chloronaphtha xanthate or butyl stearate) are added during the preparation of the grease.

Abstract: 697,180. Transmission systems. BRITISH THOMSON-HOUSTON CO., Ltd., and MOIR, J. Aug. 16,1951 [Sept. 22, 1950], No. 23286/50. Class 40 (iv). A potentiometer is arranged to take a constant output from one channel and to feed it to one or more of a number of channels in variable proportions and vice versa. A microphone 15, Fig. 1, is connected through an amplifier 16 to movable contacts 17 engaging a potentiometer resistance 10. Loud-speakers 13 are connected through amplifiers 12 to pairs of fixed contacts 11. As the contacts 17 are moved, the impedance between the contacts remain constant and the output of the amplifier 16 divided between the loud-speakers remain constant. The spacing between the movable contacts may be more or less than that between a pair of fixed contacts. Parts of the resistance 10, not included in any channel, may be left between the contacts 11 of adjacent parts. The movable contacts must then be spaced so that they can engage simultaneously corresponding contacts of adjacent pairs in order to maintain the constant impedance across the contacts and the constant output. Fig. 2 shows a similar arrangement for connecting a number of microphones 15 to one loud-speaker 13.
