Title: Recovery of elemental sulphur from gases
IPC: C01B17/04
Filed: 1974-10-15
Abstract: 1482274 Sulphur recovery AMOCO PRODUCTION CO 15 Oct 1974 44633/74 Heading C1A Free sulphur is recovered from a feed stream containing less than 45 mol. per cent H 2 S and contaminated with carbon-containing compounds by mixing a portion of the stream with a hydrocarbon fuel gas and air and burning the resulting mixture in a forward portion of a combustion zone, the air being present in an amount sufficient to convert substantially the entire carbon and hydrogen content of the fuel gas and compounds to CO 2  and H 2 O and to provide an H 2 S/SO 2  molar ratio which is above zero but not greater than 0À2, discharging the hot combustion products thus formed into a rearward portion of the combustion zone where they are mixed with the remainder of the feed stream at 2000 to 2800 F. where contaminating compounds are reacted with SO 2  and H 2 O, withdrawing as effluent from the rearward portion containing H 2 S and SO 2  in an approximate molar ratio of 2 : 1 and substantially free from contaminating compounds, removing elemental sulphur from the effluent, and reacting the H 2 S and SO 2  in the resulting sulphur-derived effluent in contact with a catalyst for the reaction to produce sulphur. In a modification of the above process, the feed stream is mixed with air and a hydrocarbon fuel gas is simultaneously and separately burnt with air in an amount in excess of that necessary to convert the fuel gas into CO 2  and H 2 O, and the products are discharged into a combustion zone where free sulphur is formed.

Abstract: 459,663. Cash registers. NATIONAL CASH REGISTER CO., Dayton, Ohio, U.S.A. July 12, 1935, No. 19910. Convention date, July 13, 1934. [Class 106 (i)] Printing on bills and like inserted material.- In a cash register or similar accounting machine of the lever-set type in which the cycle of operation may be interrupted to print identical data on a plurality of inserted slips and in which machine release is dependent on a preliminary short backward movement of the operating handle, the initial release is dependent both on the backward movement of the handle and on the restoration of the setting levers to zero, whereas subsequent release to complete the cycle is dependent only on a short backward movement of the handle. As shown, the operating handle 11 is connected through a pinion 12 and gear 14 to a wheel 15 carrying a locking plate 17. Clockwise rotation of the wheel and thus of the handle is normally prevented by the engagement of the locking plate with a notch in a pawl 20, however, upon a slight counterclockwise rotation of the handle the pawl is released and is rocked clockwise by a spring 25 to ineffective position. After a full clockwise rotation of the handle, the wheel and handle are arrested by the engagement of the locking plate with a hook 36 that is rocked downwardly at this time by a stud 34 on a lever 29 upon the clockwise rocking of the latter by a pin 26 on the gear 14. After inserting a new slip, the operator gives the handle a slight backward rotation to free the locking plate from the hook and complete the cycle. Near to the end of the cycle, the pawl 20 is returned to arresting position by an arm 23 that is rocked counterclockwise by a stud 37 on the wheel, the arm being provided with an L-shaped cam slot 22 embracing a pin 21 on the pawl and serving to cam the latter counterclockwise against the action of the spring 25. In this position of the arm 23 (shown in chain lines) the pawl 20 is locked in arresting position and is not releasable by a backward rotation of the operating handle. However, at the beginning of a succeeding operation, a lever is operated to restore the setting levers to zero and this movement rocks the shaft 24 and arm 23 clockwise to position the wide part of the slot 22 in the path of the pin 21 and permit the pawl to rock under the action of its spring as first described.

Title: Hydrofoil system for boats
IPC: B63B1/24
Filed: 1966-01-04
Abstract: 1,138,661. Hydrofoil craft. N. WADDLETON (Baker Mfg. Co.). 4 Jan., 1966, No. 46737/65. Headings B7A and B7V. [Also in Division G3] In a boat having at least two fully submerged athwartship extending hydrofoils spaced longitudinally of the hull and operating in combination with sensing means to control the pitch, elevation and roll of the boat, the hydrofoils are pivotally attached to struts that extend upwardly to said hull about axes which are from 1/8 to 1 chord above the upper surface of the hydrofoils and above and slightly abaft the hydrodynamic centre of the hydrofoils so that the hydrodynamic moment on the hydrofoils about said axes is substantially independent of the angle of attack of the hydrofoils. In the embodiment of Fig. 1, the boat has a forward hydrofoil 21 and aft hydrofoils 1, 20 pivoted to to struts (e.g. 61, 62; 2, 3) extending to shafts 22, 5 pivotally attached to the hull 9 to enable the struts and hydrofoil assemblies to be retracted. The shaft 22 is attached to the hull via a knuckle 26 so that the forward hydrofoil is rotatable about an upright axis 27 for steering the boat. The angle of the hydrofoils about said axes is set hydraulically. A diagram of the whole hydraulic system used on the boat is included in the Specification (Fig. 15, not shown). Said sensing means may comprise sensor skis. Fig. 1 shows sensing means for the forward hydrofoil 21 as comprising a forward ski 64 and aft skis 65 and 66 (not visible). Fig. 26 (not shown) shows a drag probe sensor to sense the water level forward of a hydrofoil. Dynamic pressure, i.e. a function of boat speed, may be sensed by other devices, e.g. a pitot tube device provided on the submerged portion of a strut, or a vane type sensor. The sensing means provide signals for electric retroactive control. In the Specification there are derived equations expressing the coupling relations among the signals on which a boat's hydrofoil angle control depends and the angle settings of the hydrofoils, and Fig. 28 (not shown), is a diagram of an electrical system for controlling the angles of incidence of the hydrofoils in accordance with the said equations. As shown in Fig. 14, propulsion is by a propeller 710 driven by a shaft supported in a housing 712 and connected via a universal joint at 716 to a shaft 714 driven by the boat's engine. The housing 712 has welded thereto a strut 724 which extends up into a tube 725 and is connected to the ram 736 of an hydraulic cylinder 735 for lowering the propeller to the position shown when the boat is operating on hydrofoils and raising it as shown dotted when the boat is operating in the displacement condition with the hydrofoils retracted.

Abstract: 1,089,983. Testing film cassettes. EASTMAN KODAK CO. Nov.19, 1964 [Nov. 20, 1963], No.47108/64. Heading G2A. An apparatus for testing the location of frame indexing apertures in a film in a cassette having supply and take-up chambers joined by a passageway having an exposure aperture, has means for indicating which apertures are correctly located laterally. A cassette 10 is placed on a platform 11 which is raised about a pivot 13 to a test position, wherein it is held by a magnetic latch 16 and is surrounded, and accurately located, by an open-ended box 28. On raising the platform a switch 15 is closed, which first causes a drive member 20 to engage the take-up spool in the cassette, then causes the member 20 to be driven by a motor 24 via a magnetic clutch having a faceplate 25, and also energizes each of the lamps 1 to 12 which indicate which apertures are located correctly. As the film is driven, an aperture 36 first passes a beam from a lamp 44 which is thus reflected into a photo-cell 42 which causes a perforation counter (86) coupled to the lamps 1 to 12 to advance one count; the aperture, if correctly located, is then sensed by a member 35 which, when it penetrates a correctly located aperture, completes a circuit via a contact member 40 causing the appropriate lamp 1 to 12 to be extinguished; if the aperture is not sensed by member 35 due to incorrect lateral location, the next aperture still causes the counter to advance one count so that the lamp corresponding to the incorrect aperture is not extinguished. The contact member 40 may be replaced by a balanced coil arrangement Fig.3 (not shown) which generates an electric signal when member 35 moves, and may be coupled to a cathode-ray tube. A torque facture lamp 79 is energized when the film drive is started and is de-energized when the end of the film passes a beam from a lamp 52 on to a photocell 48, unless the test is not completed in a predetermined time due to slippage.
