Inventor: PARTINGTON EDWARD
IPC: D21F5/02
Filed: 1917-11-03
Abstract: 118,511. Doverdale, E. Partington, Baron. Nov. 3, 1917. Drawings to Specification. Drying.-In drying paper in a paper-machine, a proportion of the drying-cylinders over which the paper first passes is heated to, and maintained at, a temperature higher than the temperature of the remaining cylinders, which may be maintained at a constant lower temperature or at a progressively decreasing temperature. In an example, where sixteen drying-cylinders are used, the first five are heated to 200‹ F., and thereafter there is a successive fall of 10‹ F. per cylinder.

Title: Improvements in or relating to lined cans or like containers
IPC: B65D25/14
Filed: 1939-05-31
Abstract: 529,992. Beer &c. cans. CROWN CORK & SEAL CO., Inc. May 31, 1939, No. 16039. Convention date, July 8, 1938. Drawings to Specification. [Class 66] [Also in Group III] Beer &c. cans are lined by spraying thereon a layer of varnish the exposed surface of which is composed of metal particles leafed out from the varnish into a continuous film sealing the pores or openings in the varnish layer. The coating is applied either to the blank or to the finished container. A further coating of wax, varnish, or lacquer may be applied preferably to the completed container after the bottom has been attached. The varnish employed consists of a varnish oil, a natural or synthetic resin, and a volatile mineral solvent. The metal particles consist preferably of an aluminium alloy such as aluminium bronze, but pure aluminium or other metal having leafing qualities may be used. After application the varnish with the leafed-out particles on the surface is baked before the second wax or other coating, if such is used, is applied thereover.

Filed: 1973-04-04
Abstract: 1436127 Foamed cured resin/expanded inorganic filler blends BRITISH INDUSTRIAL PLASTICS Ltd 3 April 1974 [4 April 1973] 16096/73 Headings C3C and C3R An expanded inorganic filler is dispersed into a foamed cured synthetic thermosetting resin binder containing a surfactant and being free from vegetable and mineral oil, the resin foam having been produced mechanically, and wherein a unit volume of the composition contains not less than a unit volume of the filler when determined in an uncompacted dry state and less than a unit volume of the filler when determined in a compacted wet state (i.e. when the filler has packed itself down in the wet state). The resin binder may be a urea-, melamine-, phenol-, ketone- and/or furane-formaldehyde resin or a water-extended polyester resin. The filler may be expanded vermiculite, perlite or clay, or hollow ceramic spheres of power station flyash. The compositions may be made by mixing a surfactant, e.g. dodecylbenzene sulphonic acid or a mixed alkyl aryl sulphonate with a solution, e.g. aqueous, of the resin and either mechanically foaming the solution prior to mixing with the filler or mixing the filler with the resin solution whilst agitating so as to foam it.

IPC: G01N27/16
Filed: 1951-07-10
Abstract: <PICT:0731801/III/1> A stream of gas to be analysed is passed round an electrically heated filament 1 arranged within a sleeve 10 of internal diameter not less than 4 millimetres and round a second electrically heated filament 2 arranged within a sleeve 11 of internal diameter less than 4 millimetres, and the relative change in resistance of the two filaments is measured; the heat loss from the filament 1 is substantially solely by convection, while the heat loss from the filament 2 is substantially solely by conduction.  In determining the amount of carbon dioxide in a gas, for example producer gas, water gas, or flue gas, the gas is introduced at 12 into casing 8 and passed through line 13 to casing 9; the filaments are arranged in a Wheatstone bridge circuit and the carbon dioxide content is indicated by galvanometer 15.

Title: Improvements in or relating to retorting oil shale
IPC: C10G1/02
Filed: 1922-06-14
Abstract: 202,107. Brown, H. L. June 14, 1922. Retorts and methods of working.-Oil shale in lump form is distilled in rotary retorts in which light physical shocks are given to the shale, and steam may be passed through the retorts to equalize the temperature and assist in conducting off the vapours and gases, the latter being fractionally removed and preferably employed to heat the retorts. Shale is continuously fed through a preheating rotary retort 10 having a helical fin 18 which agitates the material and propels it through the retort and down a shoot 16 to superheating or fractionating rotary retorts 30 having shockproducing baffles 54, 55, pins 56, or hammers 57. The treated shale is discharged through a passage 27 into water 6, the distillates from the preheating and superheating operations escaping by pipes 19 and 26 respectively and passing to condensing- plant which may comprise a condenser 35 having a cooling worm 43, a condenser 36 having baffles 44 and a chamber 37 filled with wire filings or shavings, separate receptacles 41 being provided for the condensates and the permanent gases escaping by a pipe 39 to be burnt for heating the retorts in burners 12, 22, and 32. The gases &c. may be withdrawn through a perforated pipe passing through the centre of a retort, and the preheating and superheating retorts may be arranged in axial communication with a steam supply to the free space above the shale.

When the slabs 2 and 3 are in position concrete is cast in the cavity 13 and is reinforced by iron reinforcements 5 and rods in grooves 4. The ribs 6 and 9 are truncated at their upper ends to form a cavity into which grouting is cast. The slabs 2 and 3 have jointing grooves 11 in their vertical edges which communicate with similar grooves 12 in their horizontal edges and the outer slabs 2 may have a groove 16 to simulate a joint midway between the ends of the slabs. Additional slabs 18 may be accommodated in grooves 17 and the space 21 filled with concrete. In a modification the limbs of the U-shaped blocks may be hollow and the ribs 9 replaced by grooves, the slabs for the inner wall being in this case secured to the studs by wire ties engaging in these grooves and in the horizontal grooves between the slabs. The blocks 1 may also have an internal rib extending between the limbs of the block. In a further modification as shown in Fig. 4 the stud-forming blocks 1<SP>11</SP> have portions 28 extending fom the base of the U-shaped portion and slabs are not required for the inner wall.

Abstract: 515,490. Decontaminating air ; valves. JEFFREYS & CO., Ltd., J., and FEHR, D. June 3. 1938, No. 16614. [Class 135] [Also in Group X] An apparatus for decontaminating air in which the entering air r normally flows through one or more filtration units is provided with a bye-pass to the units controlled by a liquidseal valve. One form of bye - pass control valve is shown in the Figure. Air enters at b and leaves at o for decontamination or is bye - passed through c. The valve comprises a bell f dipping in mercury in an annular trough d having a level indicator e. The valve is lifted by a direct pull and is retained in the open position by turning a catch l into a vertical position below a boss on the handle k. To avoid splashing and entrainment of the mercury a disc h loose on the valve spindle g engages the inner edge of the trough prior to the entry of the bell into the mercury and on the return movement is raised to a collar i on the spindle. A lift valve member p mounted on an extension of the spindle g engages a seat q to seal the conduit o when the bye-pass is open. By turning the handle k this valve may be pressed tightly against its seat. In a modification the liquid seal part of this device is housed in the casing containing the decontamination units.
