Title: Improvements in or relating to furnaces for water boilers or heaters, steam generators and other purposes
IPC: F23C99/00
Filed: 1927-04-05
Abstract: 296,715. Knupffer, M. April 5, 1927. Liquid and gaseous fuel furnaces of steam-generators, waterheaters &c. are heated by a self-contained combustion unit comprising a mass of material in which is formed a flame passage having cross-ribs adapted to intercept the flame and conduct heat to a lower part of the material where is arranged a conduit supplying fuel to burner jets, an air-heating passage being provided in or in contact with the material. As shown in Fig. 1, applied to an annular water-heater 2, liquid fuel from a tank 6 is supplied through pipes 6a, 6b to the jet 5 within the heater unit 4 which has a vertical flame passage 4<a> surrounded by refractory material and divided by radial ribs projecting from a central column 4f. The latter supports at its upper end a baffle 4b which may be rotatable and provided on its edges with fins. The base of the unit is formed by a tray 4h containing refractory material 4d covered by a removable plate 4<e>, above which latter are arranged air passages 4<c> adapted to be controlled by rotation of the tray 4h or by a separate rotatable ring. The oil supply from the tank 6 is automatically regulated by a float-valve 9 while in the pipe 6b is disposed a valve 8d operated by a thermostatic element 8 immersed in the water in the boiler 2. Any fuel overflowing from the jet 5 passes out through the passages 4<c> and is collected on a counter-weighted pivoted tray 7 which operates a valve 7<e> in the fuel pipe 6b. A funnel 6<e> and valve 6d are provided for the supply of spirit for starting. The Specification describes a modified form of selfcontained combustion unit adapted to be arranged outside the boiler or other heat-utilizing apparatus and to deliver hot gases into the heating flues thereof.

Title: Improvements in carburetors for internal combustion engines
Inventor: MENNESSON ANDRE LOUIS
IPC: F02D11/08
Filed: 1954-03-30
Abstract: 745,791. Carburetters. SOLEX. March 30, 1954 [May 21, 1953], No. 9309/54. Class 7(3) A carburetter is provided with means capable of automatically limiting to a value lower than the maximum value thereof the opening of the throttle valve means as long as the engine fed by this carburreter is running at speeds below a predetermined value. The object of the invention is to obtain higher power at low and medium speeds. Tests show that with the throttle valve in the maximum open position the powers obtained for medium and low engine speeds are lower than those obtained with the throttle valve slightly closed. The means which limit the opening of the throttle valve are operated by suction in the induction pipe, for instance in the throat of the venturi 4. As shown when the engine speed is below a predetermined value a stop 14 limits the opening of the throttle to a selected value lower than the maximum. When the speed increases sufficiently the suction on the diaphragm 15 withdraws the stop 14 and if the throttle. pedal has been fully depressed a spring 13 moves the throttle to its fully open position. The "limited maximum opening" of the throttle valve is determined by tracing power curves with the throttle fully opened and with the throttle opening slightly smaller than the maximum. The disc 7 may be provided with two or more projections disposed in stepped fashion, thus providing two or more limited maximum openings.

Title: Improvements in or relating to the purification of sulphur
IPC: C01B17/02
Filed: 1961-03-14
Abstract: Sulphur is purified by the method according to the parent Specification in which a S ore, containing 50-70% S and of less than 80 mesh size, is heated with agitation in water and under superatmospheric pressure to a temperature sufficient to cause the S to melt, including the step of allowing the mixture to cool to 200 DEG -212 DEG F. and adding sufficient S crystals in crystalline powder form to initiate crystallization of the S as globules, agitation is continued until S has solidified, the S is classified to separate a size greater than 80 mesh.  The S ore may be impure or by-product S, e.g. from the Frasch process, recovered from gas or oil purification, and may be subjected to a preliminary purification step, e.g. flotation.  The comminuted S ore, below 80 mesh, e.g. smaller than 320 mesh, is charged into a pressure vessel, of or lined with Al, Pb or glass, with a stirrer, and is mixed before or after charging with H2O in the ratio H2O: solids of 1 1/2 -4:1, or up to 7:1 when the process is continuous.  The mixture is heated under superatmospheric pressure to at least 265 DEG F. with sufficient stirring to free all the S from the gangue.  The mixture may then be transferred to another vessel where the initial pressure is reduced to atmospheric whereby the mixture is cooled, in, e.g. 5 minutes, to 200 DEG -212 DEG F.  A small amount of finely divided crystalline S is added causing the S of the mixture to form globules of 30-60 mesh which are washed and separated from the gangue in a separate vessel and dried.  The feed water may be recycled.  The S is about 99% pure.
