Title: Device for positioning within a wall of a furnace and for measuring the temperature in the furnace
IPC: G01K1/14
Filed: 1973-03-06
Abstract: 1378279 Thermocouple assemblies INSTITUT DE RECHERCHES DE LA SIDERURGIE FRANCAISE 6 March 1973 [6.March 1972 16 March 1972] 10723/73 Heading H1K A temperature measuring device for a furnace (Fig. 1) comprises a tubular sheath 1 reinforced at one end by internal annulus 2 enclosing a refractory heat conducting element 3, e.g. graphite, which is axially bored at 4 with external surface coplanar with the end of the sheath. The bore 4 may be plugged at its outer end and is coned at its inner end to receive an inserted metal sleeve 7 coaxial therewith; the tapered end being reinforced by metal member 8. An intermediate tube 11 is coaxially positioned within annular space 9 and the outer ends are closed to define cooling water passages between inlet 12 and outlet 13. A thermocouple 14 is located within sleeve 7 and axial bore 4 with its sensing extremity within the graphite element, and is connected to external instrumentation. The device is inserted in an orifice of the lined wall of a furnace with end 15 of the graphite element coplanar with the lining and is supported for slidable axial displacement in the orifice (Fig. 2, not shown). The thermocouple detects radiation in the area of the furnace wall in which it is implanted and is physically cooled by the graphite, while as the lining erodes the surface 5 may be adjusted to lie coplanar with the same. In a modification (Fig. 4) internal tubes may be formed within the sheath and the element 3 to accommodate push rods mechanically movable parallel to the thermocouple axis to displace incrustations covering the sensing surface of the element.

Title: Improvements in spray carburettors for internal combustion engines
IPC: F02M7/12
Filed: 1932-04-16
Abstract: 387,877. Spray carburetters. CAPELL, C. F., 2707, Euclid Avenue, Santa Monica, California, U.S.A. April 16, 1932, No. 10974. [Class 7 (iii).] A housing of a spray carburetter comprises a suction chamber, and a mixing- chamber bounded by a suction-operated inlet valve and a throttle valve and containing an atomizing-member which, at idling or low speeds, is operated by a suction-controlled diaphragm in the suction chamber, which is connected to the induction manifold, to supply fuel to the mixing-chamber in quantities determined by a valve rod movable within the member under control of a rocker arm operated by the diaphragm. A substantially rectangular housing 1, open at one end 7 and connected by a branch pipe 45 with an induction manifold 46, is divided into two chambers by a throttle valve 43, one chamber, which is completed by a suction-operated inlet valve 51, serving for mixing, and the other, provided with an aperture 13 closed by a diaphragm 31, as a suction chamber. A stop 92 adjusts the throttle 43 for idle running, during which engine suction lowers the diaphragm 31 drawing down an actuating-rod 38 secured to it. A pin 41 on the rod engages a rocker arm 39 causing it to rock about a head screw 91 and raise a control rod 80, to which it is pivoted by one arm 86 of a yoke. The other arm 87 of the yoke is engaged by a spring 89 tending to depress the control rod on to a valve seat 75 in the body 65 of a fuel atomizer 64 to cut off the supply of fuel entering by a channel 76, in the lower part of the body 65, and a transverse channel associated therewith. When the control rod is raised, fuel is drawn into the mixing-chamber through orifices 78 in the body, opening into grooves between fins on its outer surface, air being concentrated about the orifices by wings 93 secured to the polygonal exterior of the body and extending towards the air intake valve 51. Increased suction due to opening the throttle turns the inlet valve 51 about a pivot 50 and raises an arm 56 adjustably secured to an upward extension 52 of the valve. The arm carries a resilient head which engages the rocker arm 39 to raise it and further lift the control rod 80 a corresponding amount. To prime the engine for starting, a manuallyoperated sliding rod 97 is raised to engage a stop 98 thereon with the end of the rocker arm 39. The arm rocks about the yoke arm 86 until its other end engages an adjustable screw 60 on the extension 52 of the air valve 51, whereupon the rocker arm pivots thereabout and raises the control rod 80. In a modifioation, an air vent is disposed adjacent the atomizer between the wings 93 thereof.

Title: Improvements relating to pressure gas generating machines, and particularly to free piston machines
IPC: F04B31/00
Filed: 1940-06-27
Abstract: 551,304. Free-piston compressors. PESCARA, R. P. June 27, 1940, No. 10984. Convention date, June 29, 1939. [Class 8 (i)] [Also in Group XXVII] In a two-stroke motive-gas generator or air compressor of the free piston type having air compressing cylinders and a power cylinder to which fuel and air are supplied, the generator or compressor is operated in such a manner that one or more active cycles of the free piston assembly alternate with one or more neutral cycles of such a stroke length that the scavenge and exhaust ports of the power cylinder are only slightly opened or not opened so that scavenging is incomplete or does not occur, the delivery of air by the compressor piston being reduced or ceasing during the neutral cycles. Fig. 1 shows a free piston gas generator for driving a turbine T, having air compressor pistons 5<SP>1</SP>, 5<SP>1</SP> operating in cylinders 6<SP>1</SP> 6<SP>2</SP> and pistons 1<SP>1</SP>. 1<SP>2</SP> operating in the power cylinder 2 provided with an air inlet port 3 and exhaust port 4 connected through a pipe 16 with the turbine. Fuel injectors 12, 32 are provided and air compressed by the pistons 5<SP>1</SP>, 5<SP>2</SP> during their outward strokes passes to a chamber 11 and enters the cylinder 2 through the port 3 for combustion and scavenging purposes. A cam 14 attached to and moving with the pistons actuates a main fuel supply pump 13 supplying the injector 12 and a pump supplying a small quantity of fuel to the injector 32. The neutral strokes are provided at low outputs by shutting off the fuel supply to the injector 12 automatically in accordance with the pressure in the gas delivery pipe 16. This pressure is communicated to a spring-loaded piston 22 in a cylinder 23. As the pressure falls the piston displaces through a lever 21 a rotary cam 19 having cam surfaces which engage the spindle 18 of a spring- loaded valve 17. During the closure of the valve fuel flows from the pump to the injector and all the strokes of the generator are active. When the valve is opened by the cam the fuel escapes through the valve and neutral strokes occur, the duration of the active and neutral strokes depending on the shape of the cam. The injector 32 supplies a small quantity of fuel to the power cylinder during neutral cycles. The fuel supply pump is controlled during higher output of the generator by the turbine governor through a rod 25 and member 15, the working range of the rod 25 being controlled by an abutment member 26, 27 pivoted to the lever system 21. Fig. 2 shows a compressor in which the air compressor cylinders 6<SP>1</SP>, 6<SP>2</SP> discharge into a reservoir 33 and also into the chamber 11 surrounding the power cylinder, the air pressure being utilized to control the active and neutral cycles.

Title: Process of Manufacturing Gaseous Fuel.
Inventor: ROSE JAMES REUBEN
IPC: C10G9/00
Filed: 1917-08-03
Abstract: 116,406. Rose, J. R. Aug. 3, 1917. Oil gas; carburetting.-Gaseous fuel suitable for use in the cutting and welding arts is made in a producer comprising two similar generators 1 each having two chambers 3, 4 filled with refractory material 2<a>, the chamber 3 carrying across its top a retort 12 which opens into the chamber 3 of the other generator. The chambers 3, 4 are preheated to a temperature between 1600‹ and 3000‹ F. by the combustion of a mixture of hydrogen &c. from a pipe 9 and air from a pipe 7, to which may be added liquid hydrocarbon or steam and liquid hydrocarbon, introduced by the pipes 9<b> and 9<c> respectively. Into the retort 12 is introduced by a pipe 15 a mixture of liquid hydrocarbon and dry steam, which is heated during the preheating and discharged into the top of the chamber 3 of the adjacent generator. After the preheating, a mixture of hydrogen, liquid hydrocarbon, and steam, the latter preferably superheated and in excess, is passed through the generator, resulting in dissociation of the hydrocarbon and steam and partial recombination, the gases produced consisting of CO2, nascent hydrogen and oxygen, and a hydrocarbon, the oxygen being ready to combine with the mixture from the retort 12. The combination of the nascent hydrogen with the carbon in the liquid fuel contained in the mixture discharged from the pipe 9 and from the retort 12 results in a gas of higher carbon content than that of the original constituents. The generators are preferably worked alternately, so that while one is in operation the other is preheating.Relief valves 11, 17 are provided for the chambers 3, 4 and for an exit pipe 16, the latter leading into a receptacle 16<a> containing an absorbent for the CO2. The gas then passes by a pipe 18 through a scrubber 19, and is finally further enriched by bubbling it through liquid hydrocarbon in a tank 24.
