Title: Improvements in or relating to the elevation of granular or like material
IPC: B01J8/00
Filed: 1950-03-02
Abstract: <PICT:0673229/III/1> <PICT:0673229/III/2> In processes involving the circulation of granular material along an upflow or lift path and a downflow path for contracting process fluid, a method of elevating the granular material consists in introducing the material into a confined zone in open communication with the inlet to the lift path, passing the material down as a moving bed towards the inlet, and continually introducing lift gas or air under pressure into the zone, at least a portion of the air being introduced as a confined downwardly discharging stream laterally of and adjacent to said inlet.  In a process for cracking hydrocarbons the catalyst C, contained in a container 1, is conveyed pneumatically through a vertical lift pipe 2 to a separating chamber 3 and fines separator 5 and passes down to its place of use which is a reaction chamber 9 followed by a reactivating kiln 11, and thence back to a container 1. The catalyst flowing into the container 1 forms a one-sided mound with a sloping surface 1a.  The lift pipe 2 projects well below this and a sleeve 13 surrounds the pipe 2, being positioned concentrically of the pipe by means of vanes 20 secured to it internally.  At its upper end the sleeve 13 is carried by a pair of rods 16 slidable into and out of the container, and these are in turn extended upwardly by adjusters 17 and hooks 18 which are hooked on a pair of brackets 19 on the pipe 2.  By adjusting the adjusters 17 the elevation of the lower end of the sleeve with respect to the lower end of the pipe 2 can be varied.  Air or gas is supplied to the upper end of the chamber through a pipe 14, the flow being controlled by a valve 15. In operation the air or gas exerts a pressure on the catalyst and also passes down inside the sleeve and blows the catalyst into the pipe 2.  The elevation of the sleeve 13 controls the rate of flow of the catalyst upwardly through the pipe 2.  In a modification, Fig. 3, air or gas is also supplied through a pipe 30 upwardly into the catalyst below the end of pipe 2.  A common supply pipe 24 has a valve 25 controlling total supply or air or gas and branch pipes 26 and 28 leading to the upper end of chamber 1 and to the pipe 30, respectively, are each provided with a valve 27, 29 respectively for adjusting the ratio of the two flows.  In this case a fixed sleeve 23 having perforations 23a is used.  The results obtained under typical conditions are tabulated for (1) the first form using different heights of the lower end of the sleeve above the end of pipe 2 and (2) the second form using a constant total air flow but varying the ratio of flow rate through pipe 26 to flow rate through pipe 30.  In the first form the sleeve height controls the flow of catalyst approximately linearly.  In the second form the rate of flow through the pipe 30 provides a fine adjustment of the catalyst flow rate.

Title: Process for softening and improving the feel of textiles
IPC: D06M15/53
Filed: 1938-02-23
Abstract: 511,545. Treating textiles with liquids. GROVES, W. W. (I. G. Farbenindustrie Akt.-Ges.). Feb. 23, 1938, No. 5752. [Class 15 (ii)] Textiles are treated, for the purpose of softening them and improving the feel, with a liquid containing an alkyl-biguanide having at least 10 carbon atoms in the alkyl residue or a salt thereof, and a dispersing agent which is free from acid groups. The dispersing agent may be an oxy-ether or oxy-ester respectively of a fatty alcohol of high molecular weight, of an alkyl phenol of high molecular weight, or of a fatty acid containing at least 10 carbon atoms, and it may be a polyglycol or polyglycerol ether or ester. The treatment is effective whether or not the treating bath contains acid radicals which tend to form sparingly soluble precipitates with the biguanides. Dodecyl-, tetradecyl-, cetyl-, octodecyl, or 9-octodecenyl-biguanide, may be used. The dispersing agent may be iso-octylphenol, or an ester of glycol, polyglycol, glycerol, a polyglycerol, erythritol, or sorbitol with a soap forming fatty acid, or a hydroxyethylated derivative of such compound. The treatment is applicable to animal or vegetable fibres including artificial fibres such as viscose, cuprammonium, or cellulose acetate artificial silk. In an example, an aqueous paste containing n-octodecylbiguanide hydrochloride and oleyl alcohol polyglycol ether is diluted with a large amount of water and the solution is used for treating artificial silk. Mixtures of noctodecylbiguanide acetate and polyhydroxyethylated isododecylphenol, or n-octodecylbiguanide tartrate, succinate, or salicylate, and oleyl alcohol polyglycol ether may be used. In another example, n-octodecyl-biguanide hydrochloride is melted with a reaction product of 1 mol. of stearic acid with 6 mols. of ethylene oxide. Viscose artificial silk is treated with a solution of the mixture. Instead of the polyglycol ester there may be used a stearic acid polyglyceride. These esters may be in part replaced by mono-esters of fatty acids with polyhydric alcohols, ether-alcohols, or di- or triethanolamine. A mixture of the biguanide hydrochloride with stearic acid polyglyceride and polyglycol ethers of triethanolamine stearate may be used. In another example, n-octodecyl-biguanide hydrochloride is melted with oleyl alcohol polyglycol ether and triethanolamine stearate and a solution of the mixture is used for softening artificial silk. A similar mixture may be prepared in which there is used a triethanolamine stearate which has been etherified with ethylene oxide. Specification 380,431 is referred to. The Provisional Specification describes the use with dispersing agents, of other bases of high molecular weight, e.g., n-octodecyl-, 9-octodecenyl-, or dodecylamine, guanidines, stearyl-methylene-diethylamine, or imidazole derivatives.

Title: Improvements in or relating to mechanism for oscillating a shaft journalled in a reciprocating member
IPC: B21J9/18
Filed: 1943-04-10
Abstract: 580,808. Converting rotary into reciprocating motion. WILCOX, R. L., and WATERBURY FARREL FOUNDRY & MACHINE CO. April 10, 1943, No. 5788. [Class 80 (i)] [Also in Group XXII] Consists in mechanism for oscillating a shaft that is journaled in and moves with a reciprocating member. As applied to the movement of a punch carrier transversely to a reciprocable gate of a header or upsetting machine, a crankshaft 11 journaled in a frame 10 reciprocates by a rod 13, a gate 12 on the front face of which is a carrier slide 15 which it is required to move transversely across the end of the gate to bring one of two punches 17 opposite a die 18. This slide is connected by a link 21 to a crank-arm on a shaft 19 journaled to oscillate in the gate, the oscillation being obtained from the continuously rotating shaft 11. A gear 25 on this shaft meshes with a gear 24 on a shaft 23 journaled in the frame 10 and to which a sleeve 26 is secured. A flange 27 on this sleeve has elongated holes 56 through which pass bolts 28 to adjustably secure to the sleeve a gear 29, the adjustment being for timing purposes. A rock-shaft 31 journaled in blocks 30 on a gate 12 has fixed thereon a sector gear 32 which meshes with a pinion 33 on the shaft 19. A shaft 34 journaled in the gate has a gear 35 and cam 36, Figs 5, 7, secured thereto. On each side of the cam and moving over a block 40, Fig. 7, journaled on the shaft 34 is a slide 37, the two slides being connected to an arm 38 on the hub of sector gear 32. The slide is actuated by the cam through bowls 42. A gear frame comprises two parallel bars 44, Figs. 2, 6, spaced by shafts 45, 46 and journaled by a block 50 on shaft 23 and carrying at the other end a block 51 in which is fixed a shaft 52 on which are journaled links 53 journaled on shaft 34 which is rotated from the crank-shaft through gears 25, 24, 29, 48, 49, 54 and 35, Figs. 2, 7. As the gate 12 reciprocates, the carrier slide 15 is moved by the cam 36, slides 37 arm 38, sector 32, gear 33, shaft 19 and link 21 transversely on the end of the gate to bring the punches successively into register, with the die. All the mechanism may be immersed in lubricant in a chamber 65. In a modification, Figs. 9-11 (not shown), a sprocket and chain drive replaces the train of gears between the shafts 23, 34.

Heading B1T, In a gas filter comprising a plurality of filter pockets 2 each opening at a lower corner to a slot 5 in the wall 4 of the filter housing, each pocket communicates through a separate valve 10 either with filtered air outlet 7 or a supply of reverseflow scavenging air c, the valves 10 each comprising a tongue 12 having spaced apertures which slides between tongues 11,13, apertures in tongue 12 aligning with those in either the upper or lower part of tongue 11 (Fig. 2, not shown). The reverseflow air may be induced from atmosphere by a sub-atmospheric pressure in the filter housing. In operation, pockets in positions one and two, then those in positions two and three, and so on, are subjected to pulsating reverse flow by repeated actuation of their solenoid-controlled valves 10, whereby successive spaces between adjacent pockets are subjected to reverse flow from both sides, and dust dislodged therefrom falls into a hopper rather than being carried on to adjacent normalflow pockets.
