Title: Improvements in two-cycle internal combustion engines
IPC: F02B75/02
Filed: 1927-04-22
Abstract: 294,281. Curtis, C. G. April 22, 1927. Cylinders, ports and passages of and baffles for guiding charge; two-stroke-cycle engines.-In a two-stroke-cycle engine cylinder having an arcuate bank of piston-controlled inlet ports 19, the area of the ports is greater than that of the bars between them, the top and bottom walls of the ports are transverse to the cylinder, and the outer ports are directed to the inlet side of the cylinder, as shown in Fig. 2, and may be wider than the remainder. The piston head. is convex and may be shaped as a dome, a cone, a frustum of a cone, or a modification of these forms. For supercharging, additional inlet ports 19', Fig. 9, controlled by non-return valve, may be arranged to overlap the upper wall of the exhaust ports, as shown; in a double-acting engine, additional ports may be arranged each side of the ports 19 or only on the piston-rod side; the scavenging air is supplied under pressure so that it continues to be delivered after the exhaust ports 17 are closed. Another method of supercharging comprises inlet ports which are uncovered by the piston before the exhaust ports, and an engine-driven valve in the inlet passage which is closed until the exhaust ports are open. A further method comprises dividing the exhaust ports into two rows 17<2>, 17<3>. Fig. 18, by a thin wall and providing valves 17<x> in the upper ports, which are closed after the piston has covered the ports 17<3> on its upward stroke; in a double-acting engine, valvecontrolled ports may be arranged both above and below the ports 17<3>. The additional inlet ports 19<1>, described above, and two sets of valve-controlled exhaust ports, may be provided, e.g. controlled by separate valves, as shown in Fig. 22, or by a single valve controlling the ports alternately, as shown in Fig. 23; the exhaust ports being closed when the piston has covered the inlet ports on the compression stroke. In an opposed piston engine, the inlet ports may extend round the cylinder in the form of a number of the above-described banks, as shown in Fig. 13.
Patent GB-108072-A (GB)
IPC: F02B1/00
Abstract: 108,072. Riper, L. C. van. Aug. 29, 1916, [Convention date]. Valves. - In an engine in which air and combustible mixture are compressed in separate cylinders and in which the compression of the mixture is completed before that of the air, the air is injected into the cylinder containing the mixture after the piston therein has commenced its working stroke. The invention is described in connexion with an engine having three cylinders, two of which 1, 2, work on a four-stroke cycle and the central one 3 as an air-compression pump and an expansion cylinder. Each cylinder has a pair of oppositely-moving pistons. The distribution to and from each of the cylinders 1, 2 is controlled by the conjoint action of a sliding sleeve valve 9, actuated from a half-speed shaft, and a rotary valve 23 having a port 67 which registers alternately with mixture inlet and exhaust ports 43, 42 respectively, in the wall of the cylinder. The rotary valves are driven through toothed gearing from a shaft 35 which rotates at the same speed as the crank-shaft. A rich mixture is drawn into the cylinders 1, 2 during their suction strokes and at the end of compression this is supplemented by a highly compressed charge of air discharged from the central cylinder through ports 54 which register with ports 50 in the sleeve valve 9. Ignition occurs when the cranks of the outside cylinders are just past the dead centre whereupon expansion takes place simultaneously in the central cylinder and in one of the outer cylinders. Communication between the two cylinders is not cut off until combustion is complete which occurs when the cranks of the pistons 4, 16 are 25 to 35 degrees past the dead centres. Combustion gases from the cylinder 3 are exhausted through lift valves 37 actuated by cams on the shaft 35. The cylinder 3 is charged through piston-controlled terminal ports 44, 45 with air compressed in the crank casing and by the upper ends of the pistons 4, 5 and 6. Admission to the crank case is controlled by a rotary disk valve mounted upon and actuated by the shaft 35. Fuel injection nozzles may be fitted in the transfer passages between the cylinders, the fuel being sprayed by the highly compressed air discharged from the cylinder 3. Two or more engine units may be arranged in line V-fashion or radially.

Title: Improvements in or relating to process of production of carbon black
IPC: C09C1/50
Filed: 1948-04-20
Abstract: <FORM:0679818/III/1> Carbon black is produced by establishing in a generally cylindrical first zone having a diameter greater than its length a rotating mass of hot combustion gases, preferably previously produced, by injecting thereinto hot combustion gases, continuously injecting additional hot combustion gases to the rotating mass, continuously passing a portion of the rotating gases into a generally cylindrical second zone the length of which is greater than its diameter and the diameter of which is less than that of the first zone, the second zone being in communication with and axial alignment with the first zone whereby a helical movement of the gases is provided along the walls of the second zone, introducing vaporous hydrocarbon along the axis of the first zone and passing it into the second zone forming carbon black, and separating carbon black from the effluent gas.  The hydrocarbon, e.g. gas oil, kerosene, gasoline, butane, pentane, heavy or light naphthas, natural gas, low temperature coal gas, coal tar or shale distillates, including saturated or unsaturated hydrocarbons, paraffins, olefins, aromatics, or naphthenes, which may be preheated to 675 DEG F is injected, or sprayed or atomized in the case of liquid hydrocarbons, through pipe 16, with or without air from annular jacket 17, into refractory, e.g. sillimanite or alumina, lined furnace 10 having insulation 12 enclosed in steel shell 13.  Fuel, e.g. hydrocarbon oils or gases mixed or not with methane, powdered solid fuel, natural gas, water gas, coal gas, or hydrogen, and air are introduced into combustion zone 14 in a direction tangent to the inner walls through burners 15, the proportion of air to fuel being such, e.g. 6.6-20 preferably 10-16 vol. air per vol. fuel, that complete combustion is effected before the combustion products pass out of zone 14, which is maintained at about 3000 DEG F.  The hot combustion products flow into reaction zone 11 at about 2600 DEG F and prevent carbon deposition by forming the helically moving layer.  The effluent passes through water jacket coolers 42, water spray 46, and air cooler 48 to separator 49 whence carbon black is removed.  The radius of the reaction zone 11 is less than that of the combustion zone 14 by a distance greater than the radial extent of the tangential introduction of fuel and air.  Three alternative tangential fuel inlets are described to effect complete combustion of the fuel before contacting the axial hydrocarbon.  Specifications 621,031 and 679,819 are referred to.
