IPC: E02F3/30
Filed: 1926-05-18
Abstract: 263,022. Morin, G. G. May 18, 1926. Scoop-arm machines.-Tripping mechanism for the doors of power shovels comprises a cable wound on a drum, means acting on the cable to take up slack, and power means independent thereof adapted to rotate the drum to wind in the cable. In Figs. 1 and 2, the latch of the bucket door is connected by a chain 10 to a lever 12 which is pulled by a spring 18 and is connected to a cable 14 passing to a drum 17 fixed to a shaft 19 to which is also fixed a drum 22 carrying a cable 23 from which is suspended a weight 25 sufficient to keep the cable 14 taut without releasing the latch. Between the drums 17, 22 is fixed a ratchet wheel 21; the piston of a cylinder 37 is secured to a plate 27 carrying a rack which is yieldable against a spring 30 and which, on admission of fluid to the cylinder, cooperates with the ratchet wheel 21 to wind in the cable 14 and trip the latch. Springs 39, 4C return the plate 27, the rack and the piston. Fluid supply to the cylinder is controlled by a valve 47 normally held by springs 50 in the position shown in Fig. 2, the cylinder 37 then being open to atmosphere through ports 44, 45; by means of a cable 48, the valve may be moved tc admit fluid from a pipe 41 through port 45 tc the cylinder. The cable 48 passes over a pulley to a bell crank lever 54 pivoted to the shovel control lever 55 about an axis at right angles tc that of the lever pivot. In a modfication, Fig 10, for a shovel having a constantly-driven part connected drums 65, 64, similar to drums 17, 22, are loosely mounted on a shaft 59 carrying a constantly-driven sprocket 58 and a friction member 62; the bell crank 54 rocks a crank 75 which, through a screw 71 and sliding key 68 moves the drums to engage friction members 62, 63 when the latch is to be released.
Patent GB-738337-A (GB)
Title: Di-quaternary ammonium compounds and process for the production thereof
Filed: 1953-05-07
Abstract: The invention comprises compounds of the general formula <FORM:0738337/IV (b)/1> where R denotes an alkyl group with 1 to 3 carbon atoms, R1 denotes an alkylene group with 4 to 6 carbon atoms and Hal denotes a halogen (Cl, Br, I).  Such compounds are obtained by quaternization of an o ,o 1-dihalogenodialkyl ether, which may be obtained by reacting, an a ,o -alkyldiol containing a group R1, or the corresponding monosodium derivative, with an excess of an a ,o -dihalogenoalkane containing the group R1 and treating the resulting o -halogeno, o 1-hydroxydialkylether with a halohyrdic acid.  Where this latter compound is the chlorine or bromine derivative, it may be converted into the iodide, before quaternization, by treatment with an alkali metal iodide in alcoholic solution.  The products can also be obtained by reacting the o ,o 1-dihalogenodialkyl ether with a dialkylamine and quaternizing the product with an alkyl halide, this method allowing the production of compounds having different "R" groups.  Compounds of the above formula where "Hal" represents the iodide ion can be obtained by treating the corresponding chloride or bromide with an alkali metal iodide in alcoholic solution.  In examples (1) 5,51-dibromo-dipentyl ether (produced by reacting 1,5-pentanediol and 1,5-dibromopentane in the presence of sodium and treating the product with hydrobromic acid) is reacted with trimethylamine to give 5,51-bis-(trimethylammonium) - dipentyl ether dibromide; (2) the dichloride is prepared analogously to the dibromide of (1); (3) 5,51-di-iododipentylether (prepared by heating the corresponding dichloro-compound with sodium iodide in anhydrous alcohol) is reacted with trimethylamine to give 5,51-bis-(trimethylammonium)-dipentylether di-iodide.  The same product is obtained by the method of (1), starting from di-iodo-pentane and pentanediol, or by reacting the corresponding chloride or bromide with sodium iodide in alcoholic solution; (4) 4,41-dichlorodibutyl ether is converted to the di-iodo-compound and quaternated with trimethylamine to give 4,41-bis-(trimethylammonium)-dibutyl ether di-iodide; (5) 6,61-bis-(trimethylammonium)-dihexyl ether di-iodide is prepared by treating the corresponding chloro derivative with sodium iodide in alcoholic medium; (6) 5,51-bis-(triethylammonium)-dipentyl ether di-iodide is obtained similarly to example (1) using triethylamine in place of trimethylamine; (7) 5,51 - dichloro - dipentyl - ether is reacted with diethylamine hydrochloride to give 5,51-bis-(diethylamino)-dipentyl ether, which is reacted with methyl iodide to give 5,51-bis-(diethylmethylammonium)-dipentylether di-iodide.

Title: Improvements in or relating to regeneration of hydroforming catalyst
IPC: B01J23/96
Filed: 1955-05-04
Abstract: <PICT:0780528/III/1> A hydroforming catalyst contaminated with carbonaceous and sulphur-containing deposits is regenerated by oxidizing the deposits at an elevated temperature with an oxygen-containing gas, the conditions being such that the flue gas from the regenerator contains some, but less than 1 per cent by volume, free oxygen. In this way the sulphur deposits are removed as gaseous sulphur dioxide and are not converted to sulphur trioxide which would remain in the catalyst.  As shown, air is fed through line 18 to regenerator 14 and the air flow is controlled by valve 17 which is operated according to the oxygen content of the flue gas as determined in oxygen analyser 16.  The operation of valve 17 may be manual or automatic.  A constant pressure is maintained upstream of valve 17 by means of controlled valve 21.  The catalyst may be molybdenum oxide or platinum supported on active alumina. Oxygen-enriched air may be used in place of air for regeneration.ALSO:<PICT:0780528/IV (a)/1> In a hydroforming process, the catalyst contaminated with carbonaceous and sulphur-containing deposits is regenerated by oxidizing the deposits at an elevated temperature with an oxygen-containing gas, the conditions being such that the flue gas from the regenerator contains some, but less than 1 per cent by volume, free oxygen (see Group III).  The process is especially suitable for treating high-sulphur naphthas.  As shown, preheated vaporized oil is fed through line 2 to reactor 1 containing a fluidized bed of molybdena-alumina catalyst.  Hydrogen-containing gas enters through line 6 from separator 3 and heater 5. Hydroformed vapours pass to cooler 8 and separator 3, product being withdrawn through line 11.  Catalyst is withdrawn from the reactor through line 12 continuously or intermittently and carried by air from line 13 into regenerator 14.  Means are provided to measure the oxygen content of the flue gas in line 15 and to adjust the flow of air through line 13 accordingly.  In examples, hydroforming is carried out at 900 DEG  F. and 200 p.s.i.g. pressure, using a feed having a sulphur content of 0.13 per cent; the product has an increased octane number and a sulphur content of 0.0012 per cent.

Abstract: 1,132,743. Break-spinning apparatus. VYZKUMNY USTAV BAVLNARSKY. 25 March, 1966 [7 Dec., 1965], No. 13237/66. Heading D1D. A yarn-outlet element for apparatus for break-spinning using a rotary spinning chamber, comprises a support member constituting a slide-path for the yarn entering the channel, through which it leaves the apparatus, the length, as measured along the yarn, of the path from the inlet of the channel, and of the path from the collecting-surface varying during a revolution of the spinning-chamber. As shown, the path is provided by a ring 11 disposed above the channel 6 through which the spun yarn is withdrawn, and eccentrically of it. During the rotation of the chamber, when the yarn is in the position shown, the friction of the yarn against the ring produces a concentration of twist in the portion b between the ring and the collecting surface 3; the comparatively low twist in the portion a between the inlet 9 and the ring enables the twist imparted by the relative rotation between the chamber and the axially-fixed withdrawing rollers 7 to run back into the portion a. As the yarn rotates from the position shown through 180‹, the portion a gradually becomes shorter, and the twist in it is transferred to section b in which the frictional effect of the ring, and consequently the concentration of twist, is decreasing. The effect of the ring, therefore, is to strengthen the yarn between the delivery channel and the collecting surface, and reduce the chance of breakage.
