IPC: F16C11/04
Filed: 1928-04-19
Abstract: 314,880. Etablissements E. Jaeger. May 10, 1927, [Convention date]. Divided on 290.218, [Class 12 (ii), Lubricating passages &c.]. Flexible shafts; shaft couplings.-A flexible shaft 63, having a polygonal coupling-head 62 to engage a socket 61 in the driven shaft 16, runs in a sheath 68, which fits over a bearing bush 13 for the shaft 16 and is adapted to be ccnnected to the bearing support 5 by a form of bayonet joint. The base of a casing 12, secured to the support 5 and enclosing the bearing 13, is formed by two segments 64, and between them are introduced the protruding ends of a U.shaped collar 70, which passes through slots in the sheath 68 and engages a groove 72 in the coupling-head 62. Entry of the collar 70 into the casing lifts a spring-pressed washer 65, which, when the sheath and collar are rotated through 90‹, holds the collar-ends in place between pairs of small protruberances 67 produced by a punch. The bearing 13 is lubricated through passages 78 by a moistened wick 77 in a prolongation of the socket 61. The coupling-device may be used also for connecting together two flexible transmissions or, with modifications, two rigidlycarried members.

IPC: F28D9/00
Filed: 1963-05-22
Abstract: 963,002. Air heating stoves. COLOMBO COMMERCIAL CO. Ltd. May 22, 1963, No. 20460/63. Heading F4S. An air heating apparatus comprises a metal combustion chamber 3 on a cylindrical part 1 of which are formed longitudinally extending external fins 2, the chamber being closed at one end by a flat cover-plate 6 and at the other end by a hollow metal structure 4 of a general conical form convergent in the direction away from the combustion chamber, and having axially directed external fins 5. An annular exhaust jacket 7 having one end closed and the other communicating with an annular manifold 10, envelopes the finned wall of the combustion chamber. Air to be heated, which may be induced by a fan (not shown) flows first through an annular passage 11 formed around the outer wall 12 of the exhaust jacket by an outer cylindrical wall 13, and then through a passage 14 formed between the exhaust jacket and the combustion chamber wall. The heated air leaves the passage 14 through an exit formed by a funnel 16 leading to a duct 17. Combustion gases, which may be assisted by a forced draught fan, leave the combustion chamber via ports 18, which are connected to the exhaust jacket 7 by externally finned ducts 19. One or more tubes 21 connect the exhaust manifold 10 to a flue 22. The flat end closure plate 6 may be provided with a manhole and manhole cover 23, to facilitate cleaning of the chamber. A plate 24 carrying a fluid fuel burner may be mounted on the manhole cover 23. The air heater may be mounted upon a foundation or platform 26 by means of a fixed pedestal 27, movable pedestals 28 and a movable flange and foot 29, thus permitting expansion.

Title: Improvements in or relating to safety lamps for mines
IPC: F21L23/00
Filed: 1925-08-15
Abstract: 240,139. Takata, H. Sept. 16, 1924, [Convention date]. Miners' safety lamps. -A miner's safety lamp is provided with a hollow cylindrical cap a to which are fixed vertical pins d of different heights surrounding a central hole c closely fitting around a wick holder b vertically adjustable by means of a screw bolt r so that the percentage of explosive gases contained in the air can be determined by lowering the wick holder b in the hole c until the oil flame is a minimum, and comparing the height of the flame due to the combustion of the explosive gases with the heights of the pins d. The cap a is attached to an oil container m by means of a flange g on the cap having spaces h, i adapted to pass over fastenings j, k fixed to the oil container. The chimney support o is secured to a ring p, the chimney q being pressed downwards by means of a spring, so that when the ring p is screwed on to the container m a screwed portion e<1> on the support o is made to engage with a screwed portion e on the cap a which is provided with lugs pressed down against the container m, leaving a clearance as shown. When the container m is unscrewed from the ring p the cap a at first remains screwed to the support o, so that the wick holder b secured to the container m is lowered into the hole c and the flame extinguished. A projection m on the fastening k then engages with small recesses formed in the flange g of the cap a, which is then unscrewed from the support o so that it may be withdrawn together with the container m.

Title: Methods of wetting surfaces
IPC: D06M11/44
Filed: 1971-04-19
Abstract: 1348666 Hydrophilic coating WESTERN ELECTRIC CO Inc 19 April 1971 [2 Feb 1970] 20721/71 Heading B2E The ability of a hydrophobic surface to receive a coating thereon is improved by forming in an aqueous liquid medium by a hydrolysis reaction a stable colloidal dispersion of an insoluble hydrous oxide of a metal or a metalloid, and contacting the surface with the colloidal dispersion so that colloidal particles are deposited on the surface to render the surface hydrophilic. The increased wettability is permanent to leaching of the surface by rinsing. The surface may be of polyesters, polyethers, polyurethanes, polyimides, polyamides, epoxy resins, polyethylenes, polytetrafluoroethylene. The dispersion may be formed by (1) dissolving a salt in an aqueous solvent and adjusting the pH thereof until hydrolysis takes place, (2) dissolving a metal in an aqueous solvent to form a salt of the metal and hydrolysing, (3) dissolving a metal in an acid solvent and adding an alkali. The medium may be agitated and/or heated to dissolve the constituents of the medium and the pH of the medium may be adjusted to prevent the initial formation of a precipitate upon the addition of the material forming the insoluble hydrous oxide. Examples of constituent elements are Be, Mg, Ti, Zr, Sc, V, Cr, Mo, W, Mn, Fe, Co, Ni, Pd, Pt, Cu, Ag, Au, Zn, Cd, Hg, Al, In, T1, Si, Ge, Sn, Pb, Bi, La, Ce, Th or U. The salts may be nitrates, sulphates, acetates, chlorides, bromides or iodides. The term "hydrous oxide" includes oxides and/or hydroxides selected from true hydrous oxides, true hydroxides, hydrous hydroxides, hydrous hydrates. Numerous examples of wetting dispersions are given. Applications of the wetting treatment mentioned are in the manufacture of electric printed circuits, electroless plating and electroplating, photography, dyeing, glass, sewage treatment, synthetic fibres, plastics materials, leather tanning and wherever it is necessary to coat surfaces with inks, dyes, paints, adhesives and resins.

Abstract: 1334477 Rotary-piston engines AUDI NSU AUTO UNION AG and WANKEL GmbH 4 May 1972 [10 May 1971] 20819/72 Heading F1F In a Wankel-type I. C. engine the housing has peripheral and end-wall portions 1, 3, 4 through which a liquid coolant is circulated (as indicated by arrowed broken-lines) by a centrifugal-pump impeller 6 in a cavity 5, the "cold arc" of the portion 1 adjacent an induction passage 30 being uncooled. At low operating temperatures a thermotically-controlled valve 21 is open, as shown in Fig. 2, so that a proportion of hot coolant in a cavity 19 returns to the cavity 5 directly through an opening 24 and passage 25, the remainder of said coolant returning indirectly through a radiator (not shown) and connections 22, 23 for the latter. When the normal operating temperature is reached the valve 21 closes and the whole of the coolant in the cavity 19 passes through the radiator. An opening 28 allows a proportion of coolant in a cavity 11 to by-pass cavities 13, 17 so that a smaller quantity of coolant flows through these cavities than cavities 9 in the hottest region of the portion 1.
