Title: Improvements in or relating to stabilization of catalytically cracked gasoline
IPC: C10G27/08
Filed: 1952-03-07
Abstract: A process of producing a stable cracked gasoline consists in catalytically cracking a gas oil feed stock boiling above 400 DEG F. and containing more than 0.5 sulphur, fractionating the products of the cracking step and separating a distillate fraction boiling in the gasoline boiling range substantially free of hydrogen sulphide but containing substantial quantities of mercaptans consisting principally of aromatic mercaptans to the substantial exclusion of aliphatic mercaptans, and said distillate stock containing both olefins and diolefins, thereafter contacting the distillate stock with a cupric chloride reagent which is free of oxygen, said contact being conducted in the absence of oxygen, and then separating the treated distillate from the spent cupric chloride reagent.  The aromatic mercaptans may be thiophenols, thiocresols or thioxylenols. The cupric chloride reagent may be solid material supported on a carrier such as clay, bauxite, pumice or diatomaceous earth, preferably 10 to 15 per cent. by weight of cupric chloride based on carrier, or a 10 to 15 per cent. by weight solution in water.  The solution may be cupric chloride pesre or a mixture with copper sulphate and ammonium or sodium chloride.  Contact with solid reagent may be in a fixed bed where the gasoline is passed through at a rate of one volume per volume of reagent per hour, or in a slurry where one volume of reagent is mixed with 4 or 5 volumes of gasoline.  The water content of the solid reagent is controlled to about 5 to 25 per cent., usually 10 to 20 per cent. by weight.  Treatment with cupric chloride solution is conducted by intimately contacting the gasoline with the reagent at temperatures of 70 DEG  to 130 DEG F., in a proportion of 10 to 50 per cent. solution of volume based on feed. The cupric chloride must be free of oxygen and oxygen must be excluded during treatment by employing sealed apparatus or by blanketing with an inert gas containing substantially no oxygen. The cupric chloride may be regenerated by treating with insufficient oxygen or air so that a small amount cuprous chloride is retained, or by using an excess of oxygen and removing unused oxygen by blowing an inert gas through the reagent, or by employing the theoretical oxygen requirements or an excess and then blending with a controlled amount of spent reagent.  The product after cracking is distilled, and the portion having an end point of 400 DEG F. separated, uncondensed gases removed from it, and treated with cupric chloride reagent, after which the reagent is separated and regenerated.  A copper deactivator such as N, N1-disalicyal-1, 2-diaminopropane may be added in a proportion of 5 lbs. per 1,000 barrels.  The gasoline may also be treated before addition of copper deactivator, with sodium sulphide solution, or zinc sulphide on an inert carrier. Specification 667,368 is referred to.

Title: Improvements in carburettors for internal combustion engines
IPC: F02M1/00
Filed: 1935-02-26
Abstract: 455,708. Spray carburetters. CLAUDEL, C. H., Veuxhaulles, C¶te d'Or, France. Feb. 26, 1935, Nos. 6189 and 6190. Convention dates, Feb. 26, 1934 and May 22, 1934. [Class 7 (iii)] In a carburetter of the kind described in Specification 331,909, [Class 7 (iii)], and comprising in addition to a slow running nozzle and a normal speed nozzle, an additional nozzle for extra power required in hill climbing, this additional nozzle being subjected to engine suction less directly than the normal speed nozzle, the supply of fuel from the normal and hill-climbing nozzles, as determined by the difference in pressure between the inlet and outlet ends of each nozzle is regulated by the provision of separate air inlets therefor. A float chamber 3 supplies fuel for normal running through a nozzle Gp to a chamber 23 between an air inlet tube 20 and a diffuser tube 19 discharging into a Venturi 30 through passages 31 and communicating by ports 24 near its upper end with a chamber 27 supplied with additional fuel from the float chamber 3 through a passage 7, nozzle Gc and passage 9. The chamber 27 is bounded by a load tube 25 with stepped apertures 25a opening into a surrounding tube 26, this tube having a passageway over its upper end communicating with an outer tube 29 provided at its lower end with air inlets 29a. The suction drawing the fuel from the chamber 27 is less than that operating in the tube 19 and may be adjusted by varying the relative sizes of the passages 31 and apertures 25a. The nozzle Gc also supplies a nozzle Gr communicating by a passage 11 with the slowrunning nozzle. A second float chamber 2 may contain heavy fuel to a level below that of the fuel in the float chamber 3 and this fuel be put into communication with the normalrunning chamber 23 manually by raising a piston valve 16 or automatically by a thermostatic device or otherwise, the chamber 3 then continuing to supply the extra fuel to the chamber 27. In a modification, air is admitted through a calibrated orifice 36, Fig. 4, directly to the chamber 23 and projections 38 in the tube 19 direct the fuel on to the axis of the air inlet 20. The nozzles Gp, Gc may be supplied with air directly from the atmosphere.

Title: Improvements in the remote control by wireless of unmanned signal stations
IPC: H04B1/40
Filed: 1934-02-26
Abstract: 414,600. Wireless signalling. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN-EN APPARATEN FABRIEKEN, 30, Croeselaan, Utrecht, Holland. Feb. 26, 1934, No. 6208. Convention date, March 4, 1933. [Class 40 (v).] Several "unmanned" fog or other signalling stations A, B, C, are supervised from a distant control station D by means of wireless signals which are transmitted at successive and regular intervals as determined by a single clock located at the station D. The arrangement is such that no two of the unmanned stations can send out simultaneous signals likely to interfere with each other. The local stations are fitted with light-sensitive devices Na, Nb, Nc which operate small auxiliary transmitters 6, 7, 8 when fog conditions arise. These transmitters "call" the supervising station D, which thereupon sends back a control signal to bring the main signals 15, 16, 17 into operation. Alternatively the light-sensitive relays may "set" the local transmitters ready to come into operation on the receipt of the control signal from the supervisory station. A clock-driven disc U at the latter station drives cams 1, 2. The cam 1 closes a contact 13 to drive a motor M, the circuit being completed through contacts a, b, or c which determine the wavelength to be radiated or received. The motor circuit is "held" until a contact drops into a recess on the disc 4 as shown. Should a calling signal be received from station A during this interval, when the contacts a are closed another contact 12 is operated by the receiver E, and a control signal is sent by the transmitter S to energize the local fog-signal 15. The stations B and C are similarly supervised at successive and regular periods when the contacts band c are closed by the clock U at the station D.

Abstract: 139,799. Akt.-Ges. vorm. Seidel & Naumann. July 29, 1918, [Convention date]. lnk-ribbon mechanism. -In vibrator mechanism in which the vibrator operating g lever is mounted on a second lever adjustable by the platen-shift mechanism, and the actuating-member for the vibrator-operating lever is coupled thereto at a point in alinement with the axis of the second lever, the throw of the vibrator is rendered adjustable by providing the second lever with alternative pivots for the vibrator-operating lever. The vibrator 10, Fig. 7, is carried by an operating-lever 9 which is pivoted on a second lever 13, and is actuated by a vertically movable link 7, the lever 13 being in engagement with the platen-shift frame 16, and the rook-shaft 14 of the lever 13 being in alinement with the device or pin 8 that connects the link 7 to the lever 9. When the platen is shifted, the frame 16 causes the levers 13, 9 to rock about the axis of the shaft 14, and the vibrator is raised to the same height as the platen, the connexion 8 remaining stationary. The operating-lever 9 nor. mally rocks on a pin 11 on the lever 13, but the throw of the vibrator can be increased, to change the colour-stripe, by moving laterally the lever 13 and thereby causing a pin 12 thereon to engage the lever 9. For stencilling, the vibrator is silenced by setting the lever 13 in a position in which neither of the pins 11, 12 engages the lever 9. The link 7 may be connected to an arm 6 on a shaft 5, having an arm 3 connected to a link 4 which is suspended from a link 2 and is operated by the -universal bar.
