IPC: F24C13/00
Filed: 1923-07-13
Abstract: 202,965. Courtot, L. Aug. 23, 1922, [Convention date]. Boilers, arrangement of; stoves combined with boilers.-In a combined kitchen range and boiler, one side of the range 1 is formed by a tubular panel 2 for providing a hot water supply, against which is disposed a boiler 3 comprising three tubular panels in horse-shoe disposition. The panel 2 may thus be heated either by the range or by the boiler fire, or by both together. In the arrangement shown, it is connected to a circulating system including an expansion chamber 11 and a heating-coil 14 in a hot-water tank 9, whilst the boiler 3 is connected to the expansion chamber 10 and radiators 15. By means of a by-pass 18, the water heated in the panel 2 may be wholly or partly circulated through the radiators 15, returning through a pipe 23 which connects the return flow orifices of the boiler and panel. A non-return valve 24 may be provided in this pipe to prevent backflow from the panel to the boiler.

Title: Improvements in or relating to methods of heat treating inorganic compounds
IPC: C09K11/55
Filed: 1946-06-18
Abstract: Metal oxides in friable form are produced by heating metal compounds in a furnace solely by means of radiant heat so that the heat reaches the material as far as possible only through the upper surface.  The process is applicable to the decomposition of rare earth metal nitrates, and is particularly described as applied to the production of luminescent strontium and barium oxides.  Strontium hydroxide monohydrate, say, to which is added an activator such as lead or bismuth, in an alumina crucible, is placed in a furnace electrically heated from the top and already in excess of 700 DEG  C.  The foam formed is finally heated at, say, 1300-1400 DEG  C., for a period permitting growth of the oxide crystals, and after cooling, removed with a quartz rod.

Filed: 1919-07-24
Abstract: 130,594. Tremont Products Co., (Assignees of Smith, R. D.). July 24, 1918, [Convention date]. Air and gases, moistening.-In bubbling-apparatus for supplying humidified air to internalcombustion engine cylinders, means such as a float are provided for so controlling the gas outlet that the gas will be liberated at a constant distance below the surface of the liquid independently of variations in the liquid level. In the form shown in Fig. 2, a container 10 is fitted with an outlet 17 to the engine, a window 13, a filling cup 21, and air inlet 19 communicating with a swivelling pipe 29 formed with holes in the upper surface of its horizontal part 31. A rose 41 connected to a cork float 36 is mounted over these holes and the air issuing from the rose and passing up through the water is deflected outwards by the float or by a separately-provided member. In other forms, the pipe 29 may be replaced by a flexible hose; or a separate float 36<a> and sprayer 32a, Fig. 6, may be fixed to the pipe 29<a>, the upper part of the sprayer being shaped as shown; or a float shaped similarly to the float 36 and a sprayer such as 32<a> may be combined so that the float swings over the rose. The container may be formed with a recess at the bottom for the reception of the sprayer when the water level is low, and with an enlargement at the top to provide a sufficient air space to prevent water from being sucked to the engine. The Specification as open to inspection under Sect. 91 (3) (a) refers to the apparatus as being of general application for bringing a gas and a liquid into contact; and it describes also forms in which a float moving with the water level may be arranged to actuate valve mechanism controlling outlet ports in a stationary portion of a submerged air pipe. In another form, a stationary or float-controlled sprayer may be used in a container wherein means actuated 'by the engine suction are utilized to maintain the water level. This subject-matter does not appear in the Specifications as accepted.

Title: Improvements in or relating to a process of concentrating or recovering vitamin d and the products resulting therefrom
IPC: A61K31/59
Filed: 1939-06-27
Abstract: 530,548. Vitamin D. STEVENS, A. H. (General Mills Inc.). June 27, 1939, No. 18681. [Class 2 (iiij] Vitamin D is concentrated from either naturally occurring or synthetic vitamin D concentrates by dissolving the vitamin D- containing material in an organic solvent, passing the solution through tricalcium phosphate, preferably activated, washing the phosphate with an organic solvent to dissolve the adsorbed vitamin D and separating the vitamin D from the solvent by distilling off the solvent. The tricalcium phosphate is preferably activated by heating for about 2 hours at 120‹-130‹C. Solvents mentioned are petroleum ether, hexane, benzene or ether. The solution of vitamin D-containing material can be passed through a column of tricalcium phosphate or agitated with the solid. In the example a solution of activated ergosterol in petroleum ether is filtered through a column of tricalcium phosphate, the vitamin D adsorbed on the tricalcium phosphate is dissolved in diethyl ether and the solvent is then distilled off.
