Title: Carburetters for internal combustion engines
IPC: F02M1/04
Filed: 1971-01-19
Abstract: 1331867 Spray carburetters SOC INDUSTRIELLE DE BREYETS ET D'ETUDES 19 Jan 1971 [2 Feb 1970] 2471/71 Heading F1B I. C. engine carburetter comprises an auxiliary starting and cold operating device consisting of a distributor which opens a passage for fuel leading to the zone of the intake pipe downstream of the throttle; an enriching device consisting of a chamber divided by an element sensitive to the suction in the above zone and adapted to open or close as the suction is less or greater than a predetermined value, and a second fuel passage leading to a restricted cross-section portion of the intake pipe upstream of the throttle; and functions so that when the distributor is operating it weakens the suction acting on the sensitive element relative to the suction in the said zone. Fuel from a float chamber 1 passes through a main jet 6 and a passage 5 to nozzles 9 situated in venturi 10 in the main air intake pipe 8. Air enters a jet 7 to mix with the fuel. The distributor consists of a plate 13 having a large hole 27, a smaller hole 26 and an arcuate slot 43 which can be brought into alignment with holes 22, 20 and 42 respectively. When throttle valve 12 is closed and the engine is started, the suction on the downstream side of it is transmitted to chamber 18 and draws fuel through a jet 21, a passage 14 and the hole 26. This fuel mixes with air drawn through a duct 24 and jet 25 and enters the engine through passage 14b. The enriching device consists of a diaphragm 30 which partitions a chamber into a part 31 which is connected by a passageway 32 and a jet 33, to the passage 14b: and a part 36 from which a duct 39 leads to a nozzle 40 situated in the venturi. A spring 38 biases the diaphragm to a position in which a valve member 34 is held off its seat 35. The spring force is opposed by any depression existing in the space 31, and any such depression is modified by existence of the passage 41 which leads from the chamber 18 to the passage 32 and joins it on the diaphragm side of the jet 33. The sizes of the jets 25-33 are such that when the throttle is closed the depression acting on diaphragm 30 is insufficient to overcome the spring 38 and valve 34 remains open so that additional fuel is supplied through nozzle 40 to provide a rich mixture for starting. This condition prevails as long as the distributor plate 13 is in an angular position such that the slot 43 and hole 41 are aligned, and the throttle is closed or slightly open, so that a rich mixture is supplied at small throttle openings while the engine is cold in order to minimize pollutants in the exhaust gases. When the hole 41 is closed the suction acting on the diaphragm is sufficient to close valve 34, except at large throttle openings, when the enriching device again comes into operation.

IPC: C09B9/02
Filed: 1929-01-25
Abstract: 333,146. Fairweather, D. A. W., Thomas, J., and Scottish Dyes, Ltd. Jan. 2.5, 1929. Ester derivatives are obtained by the treatment of the disulphuric ester of 2-aminoanthrahydroquinone or derivatives thereof, having the 1-position free, for example chlorderivatives or their soluble salts such as the sodium salt, with an oxidizing agent, for example, potassium ferricyanide in a,n acid medium which is not acid to Congo Red, e.g. acetic acid. From the products bodies which are probably esters of hydroindanthrones are obtainable as solids by filtration, and soluble bodies giving green fluorescent solutions are isolated. The latter may be diazotized and coupled with #-naphthol. The esters are employed in dyeing and colouring. According to examples, (1) sodium #-aminoanthrahydoquinone disulphuric ester is oxidized in presence of acetic acid with potassium ferricyanide to give products from which a disulphuric ester of dihydroindanthrone, and an amino body which can be diazotized and coupled with #-naphthol, and further coupled with diazotized p-nitraniline can be isolated. (2) The liquor obtained by hydrolysis of the sodium salt of #-acetyl-aminoanthrahydroquinone-disulphuric ester is oxidized, in the cold in presence of acetic acid, with ferric chloride to give the second product of examples (1) principally ; (3) #-amino-anthrahydroquinone-disulphuric ester obtained as above, is treated as in example (2) at a higher temperature, to give a reddish-brown disulphuric ester of leucoindanthrone together with the product of example (2); (4) the 3-chlor-#-amino-ester, obtained as described in Specification 312,243 is oxidized as in Example 2 and gives similar products; (5) the 3-chlor-substituted body is treated as in Example 3 to give a dark blue precipitate probably the disulphuric ester of leuco dichlorindanthrone.

Title: Iron-chromium-aluminium alloy
IPC: C22C38/18
Filed: 1960-01-27
Abstract: A sulphur-, carbon- and oxidation-resistant alloy consists of Cr 7-8%, Al 6.5-8% and Fe the remainder, the alloy being free from contamination by oxides of Al and Cr and having an oxygen content no higher than that which corresponds to the equilibrium between calcium and oxygen at the alloy melting point.  The alloy may also contain C and Si in commercial amounts and carbide formers, the total amount of the C, Si and carbide-formers not exceeding 1.5%.  The alloy may be prepared by melting together electrolytic Fe and Fe-Cr without a slag, deoxidizing with 0.1% Al and 0.5% Mn and further deoxidizing the melt with Ca. Fluorspar is then added to the Fe/Cr bath.  A bath of molten aluminium is deoxidized with 0.1% Ca, degassed with chlorine and poured through the fluorspar slag into the Fe/Cr melt with vigorous mechanical agitation. After stratification and removal of the slag, the alloy is cast quickly.  Specification 798,892 is referred to.

Title: Drilling control system
IPC: E21B19/08
Filed: 1947-01-30
Abstract: 620,911. Earth boring. NAAMLOOZE VENNOOTSCHAP DE BATAAFSCHE PETROLEUM MAATSCHAPPIJ. Jan. 30, 1947, No. 2941. Convention date, Feb. 9, 1946. [Class 85] [Also in Groups XXIX and XXXV] In an automatic control system for rotary well boring the control factors are the tension in the hoist cable and the linear speed at which the tool descends into the well. As the tool descends, the cable drum 8 rotates, turning through a gear box 14 a shaft 16 at a much greater speed of rotation. The shaft 16 carries a brake drum 17 on which shoes 19, 119 are urged by springs 20, 120. The pressure on the shoe 19 is controlled by the tension in the cable operating an indicator 36, controlling a controller 31, which in consequence of variation in the tension of the cable varies the pressure on the diaphragm 27 of a motor valve 29. The movement of the diaphragm is transmitted to the shoe 19 by a lever 22. The pressure of the shoe 119 is similarly controlled by the speed of rotation of the shaft 16 which drives a tachometer 25 that varies the setting of the controller 32 controlling a motor valve 29. The system operating the brakes may be mechanical, electrical or pneumatic. In the case of the pneumatic system each controller consists of a housing which is directly connected to a source of pressure fluid and to a motor valve and has adjustably mounted therein a bleed-off passage 53. The rate of escape of fluid through this passage and in consequence the pressure on the diaphragm of the motor valve is controlled by a pivoted flap 44. This flap is operated by the change in condition of a Bourdon tube 40 or a solenoid due to variations in -the tension of the cable, or the rate of fall of the tool. A safety brake may be incorporated to operate on failure of the fluid or electrical supply.

Title: Improvements in perforating devices for printing machines
IPC: B41G7/00
Filed: 1934-01-30
Abstract: 419,636. Printing-machines. FROLICH, E., 28, M³hlebachstrasse, Zurich, Switzerland. Jan. 30, 1934, No. 3119. [Class 100 (i).] Perforating-apparatus.-In devices mounted in a forme for perforating sheets at the same time as they are printed in cylinder printing- machines, each perforating blade arranged parallel to the cylinder is associated with two sets of contiguous transverse blades in such a manner that the parallel blade is moved into operative position when it is beneath the cylinder, and, simultaneously the transverse blades between the cylinder and the inking rollers will be moved in operative position while the transverse blades situated at the opposite side of the cylinder and parallel blade are retracted from the operative position. Cam-strips 9, 14 are provided for actuating the parallel and transverse perforating-blades respectively, and have cam recesses 19 engaging lugs 20 on the blades so that endwise movement of the strips causes the the blades to be moved to operative position against the action of springs 17. An operating device 5 constructed as described in Specification 416,629 is mounted on the forme adjacent to each strip 9 and is operated by the cylinder as it passes thereunder to move the strip 9 endwise and thus actuate the parallel blade. During this movement, a square edge 11 on the strip 9 engages an inclined edge 15 of one transverse cam-strip 14 and moves it back to inoperative position and an inclined edge 12 on the strip 9 engages a square edge 16 on the opposite strip 14 to move it to operative position. An extension 10 of the strip 9 transmits the movement to further parallel cam strips. Both edges 11, 12 may be of the same shape, the edges 15, 16 being shaped to correspond.

Title: Improvements relating to the heat treatment of metal articles
IPC: C21D1/08
Filed: 1936-02-03
Abstract: 470,003. Heat treating. DENNEEN, F. S., and DUNN, W. C. Feb. 3, 1936, No. 3140. Convention date, Feb. 4, 1935. [Class 72] [Also in Group XII] In the heat-treatment of metal articles, the article or a portion of it is surrounded by an enclosure in which the surface of the article is heated by a flame which is moved over the surface relatively to the enclosure, and the heating period is terminated by automatically cutting off the supply of fuel to the flame through the medium of a heat- or light-sensitive device controlled by the temperature of the heated surface, the article then being quenched. When a plurality of flames are used, the intensity of the individual flames, and also their interruption, are automatically controlled. The article 11, Fig. 1, is mounted in an enclosure 12 provided with a cooling jacket 14 and opening 20, closed by a spring-controlled valve 18, for the escape of gases produced in the enclosure. Burners 16, 17 are mounted on carriers 28, 29 which are reciprocated horizontally by a lever 30 hinged at 31 and moved by a rod 32 in openings in the enclosure 12. Fitting in an opening in the top of the enclosure 12 is a chamber 48 which is shaped at its lower end to the contour of the article 11 and is provided at its upper end with a transparent cover 51 outside of which a photo-electric cell 47 is arranged, the supply of fuel to the burners being cut off by a solenoid 55 or a motor connected to the device 47. To prevent the flow of hot gases into the interior 52 of the chamber 48, a fluid, preferably a heated inert gas, may be introduced therein by the pipe 53. To ensure a sufficient heating over the entire width of the article, a group of cells such as 47 may be arranged in line and all connected in series so that control device 55 is not operated until the minimum desired temperature has been reached at all points. Simultaneously, with the interruption of the heating by the device 55, a suitable valve or valves in the pipes 56, 57 will be opened and quenching fluid will be projected through those pipes on to the heated surface of the article. A reducing atmosphere in the enclosure 12 may be provided by the introduction of a gas such as hydrogen, carbon monoxide or a hydrocarbon. To prevent oxidation by the quenching liquid, air or other gases is expelled from the same by heating under pressure, and the liquid may be aerated with hydrogen. In a modification, in which the article to be treated is rotated, the burners are mounted in the upper part of the enclosure so that they can be oscillated and the control of the fuel supply to the burners is produced by a thermo-couple mounted in a chamber similar to the chamber 48. When a hollow article is being treated, cooling liquid may be passed through its interior. A bimetallic strip may be used for the temperature control instead of the photo-electric cell or the thermo-couple. Specification 445,425 is referred to.

A cable making machine comprises a number of spaced heads 8<1>, 8<2>, 8<3> &c., Fig. 1A, the spaces between said heads being occupied by bobbin cradles 11 that float in synchronously rotating carriers 10 housed in the heads 8. Each head 8 includes a drive shaft 5<1>, 5<2>, 5<3> &c. and each drive shaft has a brake shown in part at 64. The drive shafts are coupled end-to-end. The wire from each bobbin 21 takes a path from the rotating carrier immediately in front of that bobbin and through the rotating carriers in all the other heads in front of that bobbin at the same radial distance from the axis of rotation until it is brought into a twist plate. The rotating carriers 10 are driven by driving wheels 31, each wheel 31 being slotted to mesh with a timing belt driven by a slotted pinion 33 on a drive shaft 5<1>, 5<2>, 5<3> &c., there being one drive shaft for each head 8<1>, 8<2>, 8<3> &c. There may be reversing means in any or all the transmissions between the shaft sections 5 and the various carriers 10 so that stranding or overlaying may be carried out in opposite directions. Each shaft section has brake means (not shown). Cradle. Each cradle 11 includes a pair of spaced apart spindles 48, Fig. 6, for supporting a bobbin 21. One of the spindles is mounted in an axially slidable bush 53 having a screwed end extending into a handwheel 52. By turning the handwheel 52 in the appropriate direction the spindle can be withdrawn from the bobbin 21 to release it. The other spindle 48 carries a pulley 54 acting as a brake drum for a cable 55, the tension of which is adjustable by screw and nut means 57, 58, Fig. 4 to prevent overrunning of the cable bobbin. Each cradle comprises a main casting 11, Fig. 4, the ends of which are machined to receive the respective spigots 35 and 40 by which it is pivoted in the rotating carrier 10. The wire outlet end of the cradle, which is cone-shaped as at 34, terminates in a ceramic, sintered or like wear-resistant guide 22 for the wire. Setting device. Beyond the twist plate is an axially adjustable setting device beyond which is a variable speed gear box, a capstan device and a take up mechanism. Lubrication. The rotating carriers 10 are housed in bearings 9 running under pressurised lubrication, there being oil inlet conduits at the top of the bearings and oil outlet connections at the bottom.
