Title: Process and apparatus for the continuous transformation into light hydrocarbons of the heavy hydrocarbons from petroleums and the like
IPC: C10G9/42
Filed: 1928-01-28
Abstract: 284,345. Carroll, H. Jan. 28, 1927, [Convention date]. Hydrocarbons, cracking; hydrogenation, destructive; film evaporators.-Crude oils are cracked by allowing them to flow in thin layers over surfaces heated to such a temperature that the oils assume the spheroidal state. The oils are first heated in coils a, a<1> to slightly below cracking temperature, the vapour produced being separated from the liquid portion in a dephlegmator D, the liquid portion passing to a converter M, while the cracked vapours are passed to the usual rectifiers, dephlegmators, and condensers. The dephlegmator D contains a central chamber d, Fig. 9, to which the oil is admitted by nozzles d<3> so as to strike against vanes d<5>, d<6> a mechanical cracking with simultaneous separation of vapours being thus obtained. The cracking chamber M comprises an insulated cover m<1> supported on the setting m<2> of a furnace and a hollow metallic truncated cone m<3> supporting superposed annular troughs m<4> of downwardly increasing cross section filled with fusible metals or alloys. The oil passing from a chamber d<2> filled with Raschig ring falls into a basin m<6> from which it descends over the steps formed by the metallic baths on which it assumes the spheroidal state allowing a superheating of the gaseous phase without superheating of the liquor phase The cone m<3> is heated bv burning the residual gases formed in the process in a burner, the combustion gases being delivered with a rotary motion through a partition n<3> and withdrawn through a chimney N. The residual oil collects in a trough m<2> in which a perforated pipe is provided for introducing the incondensable gases produced in the reaction, and is continually withdrawn through a filter o to separate carbon, a heat exchanger P and a refrigerator Q to a storage tank R. The member m<3> may also be formed in the shape of a cylinder or of an inverted truncated cone. The vapours pass from the dephlegmator D to a series of condenser dephlegmators E, E<1>, E<2>, coolers G, G<1>, G<2> and collecting vessels F, F<1>, F<2>. Further condensation is obtained in a tubular condenser H and the incondensable gases are separated in a separator h and pass through a scrubber I to a storage bell k.

Title: Improvements in or relating to band-pass impedance transforming networks for use on high frequencies
Inventor: KEALL OSWOLD EDWARD
IPC: H03H7/38
Filed: 1948-06-30
Abstract: 648,911. Impedance networks. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Jan. 30, 1948, No. 2875. [Class 40 (viii)] A wide band-pass impedance transformer for use on high frequencies comprises a number of stages in cascade, at least one stage at the high impedance end being a T, # or equivalent network, and at least one stage at the low impedance end comprising a quarter-wave transmission line. As shown, Fig. 3, the high output impedance of an amplifier V is matched to the low input impedance of a long length of properly terminated cable C by an impedance transforming network L1, L2,L3, C2, in cascade with a quarter-wave line QL. A blocking condenser C1 prevents the application of the H.T. voltage to the line QL. A capacitative impedance transformer may precede the quarter-wave line which may be a coaxial line or may comprise a helical winding supported coaxially with but spaced from a cylindrical outer conductor. The arrangement may be used to match the input impedance of a valve to the output impedance of a properly matched cable.

Title: Internal combustion engines
IPC: F02B/
Filed: 1974-01-22
Abstract: 1454483 Stratified charge IC engine NIPPON SOKEN Inc 22 Jan 1974 [22 Jan 1973 27 Feb 1973 8 March 1973 3 April 1973 31 Oct 1973] 02877/74 Heading F1B Stratified charge I.C. engine includes a cylinder 1, a cylinder head 4 which, with the cylinder defines a main chamber 5 for the combustion of lean mixture, an intake valve having a stem 7 and a head 7a, a suction port 6 for introducing lean and rich mixtures, a trap chamber 12 having a suction aperture 14 through which rich mixture is supplied when the intake valve is opened, the trap chamber also having at least one discharge aperture connecting with the main chamber, a spark-plug in the trap chamber, a suction passage 17 for feeding rich mixture, the passage having an open end disposed in the suction port so that the rich mixture enters the trap chamber and a wall provided between the suction and discharge apertures to prevent direct communication between said suction and discharge apertures. The surface 4b of the combustion chamber is concave and has only a small clearance from the edge of the inlet valve head 7a, so that when the valve is in the open position (shown in chain dotted lines in Fig. 1) the valve head guides rich mixture from carburetter C 2  and passage 17 into aperture 14. Carburetter C 1  supplies a lean mixture to port 6.  Operation During the suction stroke, a lean mixture (20 to 30 parts air to one part fuel) is drawn into the main chamber and the suction at discharge port 15 scavenges the trap chamber so that a rich mixture (2 to 6 parts air to one part fuel) is drawn into the trap chamber. Partition wall 16 ensures that the plug points are surrounded by rich mixture, which will be slightly diluted by some of the lean mixture. During the compression stroke there will be some further dilution of the rich mixture in the trap chamber. When the mixture in the trap chamber is ignited, torch jets from passages 14 and 15 ignite the charge in the main chamber. In a modified construction Figs. 3 and 4 (not shown) the trap chamber is formed as a separate tubular member which is inserted in the head. Fig. 5 shows a trap chamber which is open ended, the wall 16 projecting out of the chamber towards the valve head 7a so that it is closely adjacent the valve in its open position. In a second modification the end of the suction passage 17 is closed by the back of the valve head when the valve is shut, to prevent the passage being influenced by the suction in other cylinders of a multi-cylinder engine. Alternatively the valve stem passes through the suction passage and has a reduced diameter portion which is only aligned with the passage when the valve is open. In a third modification the sparkplug is arranged so that its axis is normal to the trap chamber axis and there is a port in the side wall of the chamber adjacent the spark-plug points, the plug being positioned adjacent either the suction passage 14 or discharge passage 15.

Title: Improvements in or relating to the production of artificial textile materials, films and other shaped articles having a basis of a polymerised vinyl ester
IPC: D01F6/08
Filed: 1941-03-04
Abstract: 548,387. Artificial silk, films etc.; resinous condensation products. ROBERTS, R. P., JOHNSON, E. B., and YOUNG, M.A. March 4, 1941, No. 2911. [Classes 2 (ii) and 2 (iii)] Artificial textile materials, films, and other shaped articles are obtained by shaping a solution of a polymerized mixture of a vinyl halide and a vinyl ester of an aliphatic acid in a mixture of acetone and another organic liquid, and setting the shaped materials by evaporation of solvent therefrom. The other organic liquid may or may not be a solvent at ordinary temperature. Benzene, toluene, xylene, ethylene methylene ether, dioxane, ethylene dichloride, methylene dichloride, cyclohexanone, methyl cyclohexanone, cyclohexanol oxalate, dimethyl-cyclohexanol oxalate, or methyl cyclohexanol stearate, may be used as the other organic liquid. Polymers of very high molecular weight, e.g. 10,000-25,000 or higher may be used. The polymer may be derived from vinyl chloride and vinyl acetate, propionate, or butyrate. The vinyl halide preferably predominates. More than one halide and more than one ester of an organic acid may be present in the polymer. After the filaments or other materials have been solidified by passage through an evaporative medium, they may be passed through a hot or cold aqueous bath and then wound up in or after leaving the bath. The set materials may be subjected to stretching treatments so as to increase the original length by any desired amount up to or beyond one thousand per cent, in one or more stages. In an example, a vinyl chloride-vinyl acetate polymer is dissolved in a mixture of acetone and dimethyl cyclohexanol oxalate and the solution is extruded into a dry spinning chamber in which the air around the jet is maintained at 95‹C. The formed filaments are led through a bath of water and then wound on a bobbin.

Title: Improvements in or relating to the Breech Mechanism of Ordnance.
IPC: F41A3/08
Filed: 1916-03-07
Abstract: 102,198. Vickers, Ltd., and Asbury, D. F. March 7, 1916. Ordnance breech mechanism, screw type. Relates to mechanism of the kind having a cam for causing the unlocking movement of the breechscrew to effect the initial opening movement of the breech-screw carrier, and the final movement of the carrier to initiate the locking movement of the screw. The invention consists in mounting the elements of the cam-device independently of the breech-screw, i.e., in a similar manner to the elements of the governing-cam device described in Specification 16406/15, in which one of the elements is mounted on the gun and the other on the breech-screw locking and unlocking mechanism. The invention is shown in Figs. 1, 4, and 7 applied to mechanism in which the breechscrew B is mounted upon a swinging carrier C operated by a fluid-pressure piston-and-cylinder device, the cylinder 39 of which is hinged to the gun A, the piston-rod 41 being connected to a link 42 at the upper end of a vertical breechactuating shaft 27 mounted in the carrier C. A lever 28 connected to the lower end of the shaft 27 serves to operate the breech by hand. The breech-screw is rotated for unlocking when the shaft 27 is rotated by link 32 as described in Specification 101,409. This unlocking movement serves to bring a roller 53, on a link 52 carried by the shaft 27, into engagement with a cam 51 on the gun to effect the initial opening movement of the carrier. The parts are in the position shown in Fig. 7 after the cam has operated. The further operation of the shaft 27 then swings the carrier into the position shown in Fig. 4, the rotation of the shaft 27 with respect to the carrier being prevented by the engagement of the roller 53 with a surface 49 fixed to the gun and concentric with the carrier hinge 20. The carrier is cushioned at the end of the opening movement by the engagement of the piston 40 with a hydropneumatic buffer at the end of the power cylinder 39. When the closing movement is effected by power, rotation of the shaft 27 with respect to the carrier is prevented by a stop 54, Fig. 4, on the carrier, but when the breech is closed by hand, such rotation is prevented by the surface 49, the final closing movement in each case causing the initial locking rotation of the breech-screw through the cam 51.
