Title: Improvements relating to window operating mechanism
IPC: E05F11/14
Filed: 1926-03-25
Abstract: 264,040. Newman & Sons, Ltd., W., and Newman, H. G. March 25, 1926. Pivoted-window and casement opening and closing apparatus. - A single control member 5, which is adapted to operate several hinged or pivoted windows 1, 2, is operatively connected to one or more of the windows through the medium of rigid link or lever mechanism arranged to give an idle movement and cause the opening of the said window or windows to be delaved as compared with the opening of the other windows. The windows may be horizontally or vertically hinged. The link mechanism for each window is connected to the control rod 5 by means of brackets 8, 22, so that movement of such rod operates the windows. Horizontally hinged windows are shown. The link mechanism for the upper window 1 comprises pivoted links 9, 10 connected respectively to the bracket 8 and to a rotatably mounted horizontal bar 11, and to the latter bar is fixed one of a pair of pivoted links 12, 13, the other link 13 being hinged to the window. The bracket 22 for the lower window 2 carries a roller 17 which is adapted to engage an L-shaped camslot 16 in an arm 15, the upper end of which is fixed to a rotatably mounted horizontal bar 18. An arm 20, also fixed to the bar 18, is pivoted to a link 21, which is hinged to the window 2. The bracket 22 is so adjusted that the roller 17 is situated at the upper end of the slot 16 when both windows are closed. Downward movement of the rod 5 causes the upper window to commence to open, but the lower window does not start to open until the roller 17 reaches the bottom of the vertical barrel of the slot 16. This arrangement allows one window to be opened without actuating the other window. The idle movement may alternatively be produced by a cam. The Provisional Specification also describes the provision of means for allowing the lower window to be fully opened after the upper window has already attained this position. One form of such means comprises a spring surrounding the vertical rod between an abutment and a slidable collar to which is pivoted the lower end of the link extending between the vertical rod and one arm of the upper bell-crank lever, the arrangement being that the spring allows movement of the vertical rod after the upper window is fully open. Another form of such means consists in a particular arrangement of the lower part of the cam slot of the lower window.

Title: Process and apparatus for producing a carburising gas
IPC: C10J3/00
Filed: 1938-03-17
Abstract: 512,944. Gas-producers; cracking gaseous mixtures. BRITISH FURNACES, Ltd., and HOPKINSON, P. March 17, 1938, No. 8239. [Classes 55 (i) and 55 (ii)] A charcoal gas generator comprises a structure 1 enclosing a heating chamber 1a, a base 7 incorporating one or more open top combustion chambers 8, one or more upwardly extending charcoal retorts 3 supported on the base with their lower ends in open communication with the tops of the combustion chambers, the retorts extending through the heating chamber and being externally heated by burners 2 firing therein. The generator is provided with air inlets 11, gas outlets 14, and inlets 12 and 13 for the supply of fluid fuel such as city gas, natural gas, propane gas &c. The extensions of the combustion chambers are sealed in a pan 10 filled with water or oil. In starting, the hoppers 5, retorts and combustion chambers are filled with charcoal and the retorts heated to 1600‹- 1800‹F. by the burners. Suction is applied to the outlets 14 and a torch admitted through the air inlets 11. Metered air may then be supplied through the latter to produce ordinary suction gas. To obtain a carburizing gas with economy of the charcoal, the operation is modified by supplying fuel gas through the inlets 12 to burn with the air ; excess air gives only CO2 which is reduced to CO in the retorts ; deficiency of air gives in addition CO,H2 and partly decomposed hydrocarbon, the resulting gas comprising mainly CO,H2 and CH4. Using a relative excess of air, a gas rich in hydrocarbons may be obtained by also supplying metered natural gas &c. through the inlets 13. Mainly CH4 is thereby added to the resulting gas and carbon is deposited on the charcoal. The ratio of air to gas at 11 and 12 is accordingly varied to allow the deposited carbon to be consumed.

Abstract: 1,220,464. Papermaking. PAPETERIES NAVARRE. 20 Feb., 1968 [28 Feb., 1967], No. 8273/68. Heading D2A. A fibrous web of non-woven fabric is made from a dilute suspension of fibres in a device comprising a tank (1) with two convergent wall sections (7, 8) formed respectively by an endless belt (2) and a permeable endless surface (3) both leading to an outlet between parallel sections (9, 10) and means upstream of the outlet separately operable to create a vacuum in or to feed fluid to each of a plurality of compartments (16) on the outer face of the permeable surface, the wall sections being operable to draw the agglomerated fibres into the outlet and feed them to the parallel sections to form the web. As shown, the endless belt 3 is of metal or plastics cloth or felt and runs over rollers 12 and 13 of which one imparts drive. Roller 13 may have an internal suction chest, and cleaning elements 14A and smoothing elements 14B may be provided, 15 is a perforated displaceable face plate over the compartments 16. A narrow laminar jet 17 of air or water may serve to rearrange the fibres or create areas of reduced density, e.g. hinge areas. Suction boxes 18, steam distributors 19 and compressed-air distributors 20 may be provided, the last to reach the web from the belt 3. The endless belt 2 is of metal or plastics cloth or woven or knitted felt, or may be more or less liquid-proof. It may be driven separately from but synchronously with the belt 3, or by contact, through the web, between belts 2 and 3. The roller 11 may be solid or a dandy roll. In a modification, an internal partition 24 serves as a baffle to lay some of the fibres across the plane of formation of the web. In another modification a layer of wires, netting or screen of canvas of textile or metallic material or a meshwork fabric is incorporated in the web. It may be introduced between the walls 6 and 8 or 5 and 7 or through the inside of the tank as shown at 25. In other embodiments the endless surface 3 is a metal cloth on a drum-shaped frame (fig. 2, not shown), or wall sections 7 and 8 form a V-shaped trough with the outlet at the bottom (fig. 3, not shown).
