Title: Improvements in or relating to means for regulating combustion in furnace stokers
IPC: F23H11/10
Filed: 1927-10-22
Abstract: 279,500. Smoot, C. H. Oct. 22, 1926, [Convention date]. Regulating combustion.-In steam boiler furnaces provided with travelling grates, a change in the load on the boiler produces automatically a change in the speed of the grate and also changes in the air supply to different sections of the grate in succession, the pressure of the air supply being temporarily changed until the change in the speed of the grate produces the required length of fire for the changed load. A change in the boiler load acts through a master regulator K to change fluid pressure in pipes L1, L2, L3 leading to regulating devices M, I, R. The pressure of the air supplied by the engine D through the duct H and valves E1, E2 to different sections of the grate C is communicated to one side of a diaphragm M1 the other side of which is exposed to atmospheric pressure. This diaphragm is connected by a rod M4 to a diaphragm M2, exposed on its upper surface to the atmosphere and on its lower surface to the pressure in the pipe L1, and to a diaphragm M3 exposed to the atmosphere on one side and to the pressure in the pipe L2, on its other side through the medium of a viscous fluid the supply of which to the diaphragm chamber N4 is controlled bv a valve regulating the size of the orifice N2. The rod M4 is also connected to the valve controlling the supply of steam to the engine D. Upon a change in load taking place the rod M4 is actuated to vary the speed of the engine D but is brought back to its normal position as fluid passes through the orifice N2 to the diaphragm M3. The valves E1, E2 - - are operated in succession by a cam-plate P connected to a diaphragm 11 exposed on opposite sides to the pressure in the furnace on opposite, sides of the boiler, and to a diaphragm 12 exposed to the pressure in the pipe L2 of the master control K and to the atmosphere. The steam supply to the engine B operating the grate is controlled by the joint action of a governor R2 and a diaphragm R1 exposed to fluid pressure in the pipe L3 of the master control, both of which actuate through a system of rods and levers the steam, supply valve, S of the engine B.

Filed: 1922-10-18
Abstract: 187,613. General Electric Co., Ltd., (Assignees of Skaupy, F.). Oct. 19, 1921, [Convention date]. Vacuum tubes.-A bulb, which may be evacuated, or filled with rarefied gas, has a transparent body adapted to radiate light when heated by an electron discharge between a cathode and an anode, the body consisting of one or a small number of crystals. The radiator may consist of thorium oxide or other refractory oxide, or boron nitride. A coating of cerium dioxide, coloured oxides such as chromium dioxide, or a transparent layer of metallic coloured bodies, such as titanium nitride, may be applied to the surface of the radiator, or incorporated in the surface or body of the radiator. As shown, the radiator S is mounted behind an anode A of grid form, so that electrons emitted from a cathode K pass through the anode, strike the radiator S, heating it to incandescence, and return to the anode. In a modification, a filament cathode is surrounded by a space-charge control grid, and an anode of grid form encloses the radiator. In another arrangement, the radiator is in the form of a transparent plate provided with a tungsten deposit in the shape of a design, such as a word, or with an inlay of refractory material which is more nearly a black body than the transparent plate. The tungsten deposit emits a brighter light than the transparent plate. The Specification as open to inspection under Sect. 31 (3) (a) comprises also the use of rare earths instead of thorium oxide. This subjectmatter does not appear in the Specification as accepted.

Patent GB-676650-A (GB)
Title: Improvements in or relating to motor fuels
IPC: C10L1/222
Filed: 1949-11-09
Abstract: A hydrocarbon motor fuel containing a minor proportion of an alkylene diamine, and which may or may not contain tetraethyl lead and an organic halide scavenging agent, is burnt in an internal combustion engine, in which hydrocarbon motor fuels containing tetraethyl lead and an organic halide scavenging agent have been burnt, prior to a period of idleness of said engine. The internal surfaces of the engine are thereby protected against rust.  The preferred diamines are of formula H2N-R-NH2 when R is a straight or branched chain alkylene group of 2-5 carbon atoms.  The amine groups may be attached to any carbon atom, but it is preferred that they should be attached to carbon atoms which are adjacent or separated by not more than one carbon atom.  The amount added may be between 0.03 and 5 per cent by volume, and preferably 0.1 to 1.0 per cent.  Although it is preferred to run the engine for a short time before storage using a fuel containing an alkylene diamine with or without tetraethyl lead and a scavenging agent, if desired it may be run normally on a fuel containing the alkylene diamine, as well as tetraethyl lead and a scavenging agent.  In this case, relatively smaller amounts may be employed (minimum 0.01 per cent).  In an example a fuel comprising an aviation fuel (octane No. 80), tetraethyl lead, ethylene dibromide and 0.1 per cent by volume of propylene diamine is compared with respect to its rust inhibiting properties with the same aviation fuel containing only tetraethyl lead and ethylene dibromide.
