Title: Improvements in internal combustion engines
IPC: F02B33/26
Filed: 1920-02-23
Abstract: 139,473. PrÚtot, M. Feb. 6, 1919, [Convention date]. Void [Published under Sect. 91 of the Act]. Regulating.-Fig. 1 shows a two-stroke-cycle engine having an exhaust valve in the cylinder head and a terminal port L through which scavenging-air is delivered, by a fan or other apparatus, in advance of combustible mixture compressed in the crank chamber and transferred to the combustion space through a non-return valve M. Alternatively, the crank chamber may compress the scavenging-air, combustible mixture being admitted through the port L. According to a modified construction, the air-inlet port L is located above the inlet port for the combustible mixture. The Specification states that scavenging-air at atmospheric pressure may be induced by the escape of the exhaust gases. The fourstroke-cycle engine shown in Fig. 3 may compress in the crank casing air which is transferred to the cylinder through a passage M<1> for scavenging purposes and to supplement the normal charge. Alternatively, a scavenging charge may be dispensed with, air or combustible mixture being transferred from the crank chamber to the combustion space during the suction strokes to supplement a charge of combustible mixture or air drawn in through a valve S in the cylinder head. Liquid fuel may be injected either into the cylinder or into the crank chamber. Supplementary charges may be compressed in the crank chamber for a pair of working cylinders. In either two- or four-stroke-cycle. engines, the volumes of the crank chambers may be varied, to compensate for differences in the pressure of the atmosphere at various altitudes, by altering the sizes of the crank-disks, the clearance spaces in the pistons, or the dimensions of the connecting-rods. The crank chambers may be placed in communication with supplementary chambers to increase their volume. The cylinder and pump ports may be controlled by valves.

Inventor: DALLISON GEORGE JOSEPH
IPC: F41G7/00
Filed: 1917-04-19
Abstract: 127,324. Dallison, G. J. April 19, 1917. Torpedoes, locomotive.-Consists of means for controlling navigable floating bodies automatically or from a distance, comprising a disk k capable of being turned about the centre of a pivoted master magnet a and carrying four pivoted magnets b, b<1>, b<2>, b<3> adapted to engage the stops or contacts c. When the magnets are in the position shown in the plan view, Fig. 1, with the magnet b exactly in line with the magnet a, the circuits connected to the contacts are open and the helm is stationary; but should the vessel alter its course, the magnet b moves relatively to the master magnet and due to the interaction of these magnets, the. switch magnet b is pulled over into contact with one pair of the diagonal stops c to close a circuit and set in motion a reversible motor or one of a pair of oppositely rotatable motors connected to the helm for a sufficient time to restore the proper course. If the vessel drifts, or if a distant observer desires to alter the course for any other reason, a wireless switch acts on one of the magnets b<1> or b<3> to engage the helm motor. Fig. 3 shows a simplified arrangement suitable for automatic control only, in which an auxiliary magnet d is arranged between the master magnet a and the switch magnet b.

Title: Method and apparatus for the combustion of hydrogen sulphide and the production of sulphur
IPC: C01B17/04
Filed: 1952-03-04
Abstract: <PICT:0708041/III/1> <PICT:0708041/III/2> Sulphur is prepared by the combustion of hydrogen sulphide which may contain hydrocarbons, e.g. 0.5-2 per cent. methane, by intimately mixing, prior to combustion, the hydrogen sulphide with oxygen or free oxygen-containing gas and discharging the resulting mixture at a high velocity, sufficient to prevent flash back, into a burner as described and claimed in the parent Specification (see Group XI).  Air injected through pipe 3 and hydrogen sulphide entering through 2 pass into mixing device 1 and the resultant mixture is supplied to annular gas chamber, 6, Fig. 2, tangential to the walls thereof and passes thence with increasing rotational velocity through annular slit 7 in the terminal wall of refractory cup-shaped combustion chamber 8 so that vortices of burning gas are formed at the inner and outer sides of the flame. The proportion of air to hydrogen sulphide, say 2.4 : 1, may be such as to ensure maximum production of sulphur, e.g. 85 per cent. at a combustion temperature above 1000 DEG C.  Gases from the combustion chamber may be cooled by immediately contacting them with a steam boiler to condense sulphur.  Any hydrogen sulphide in the gases may be converted to sulphur by contact with a catalyst or burned to sulphur dioxide and used for sulphuric acid production.  A continuous burning pilot flame is provided in opening 9, along the axis of chamber 8, supplied with fuel gas at 10 and air, preferably 30 per cent. excess, at 12, 11.  The pilot burner may have a nozzle and materials resistant to corrosion by the combustion products may be used at and near the openings.

Title: Phosphate polyols and their preparation
IPC: D06M15/564
Filed: 1965-02-09
Abstract: Phosphate polyols, which are stated to be unsymmetrical and to contain a substantial proportion of secondary hydroxyl groups, are prepared by adding phosphoric acid to an alkylene or cycloalkylene oxide in a liquid phase.  The reaction is generally effected in the absence of solvents by adding 1 mol. of phosphoric acid to at least 5.5 mols. of an alkylene oxide at temperatures of 0 DEG  to 150 DEG C. and at a pressure of from 1 to 30 atmospheres.  However, one or both of the reactants may be dissolved in an inert solvent such as an ether, a halo-generated hydrocarbon, an alkyl phosphate or a phosphonate.  Specified alkylene oxides are ethylene, propylene, hexylene, dodecylene and cyclohexene oxides and the isomeric n-butylene oxides.  The invention also includes mixed phosphate polyols containing randomly distributed oxyalkylene groups which may be prepared by adding phosphoric acid to a mixture of alkylene oxides such as propylene and butylene oxides or by first adding the phosphoric acid to one alkylene oxide followed by reaction of the latter product with a second alkylene oxide.  An example is given of the addition of 100 parts of 100% phosphoric acid to 366 parts of propylene oxide and a comparative example is given of the addition of 400 parts of propylene oxide to 100 parts 100% phosphoric acid.  The products are useful (i) in imparting flame retardancy to polyurethane foams (see Division C3); (ii) as plasticizers for vinyl-type resins, and (iii) for use in functional fluids.ALSO:A polyurethane foam is prepared by reacting a phosphate polyol, produced by adding phosphoric acid to an alkylene oxide (see Division C2), with an isocyanate.  In an example, a polyurethane foam is obtained from a reaction mixture comprising a phosphate polyol (obtained by adding phosphoric acid to propylene oxide), sorbitol-propylene oxide, a silicone wetting agent, 2,2,2-diazabicyclooctane trichlorodionofluoromethane, distilled water and polymethylene polyphenylisocyanate.
