Title: Separation of hydrocarbons
Filed: 1957-07-24
Abstract: <PICT:0848467/IV(b)/1> In the separation of straight chain hydrocarbons from mixtures also containing branched chain or cyclic hydrocarbons using a molecular sieve, the adsorbed hydrocarbons are desorbed by heating the sieve in a high boiling liquid not adsorbed by the sieve to a temperature of 200 DEG -600 DEG  F.  Suitable high boiling liquids are branched or cyclic hydrocarbons particularly alkyl or aryl aromatics particularly diphenyl, diphenyl oxide and mixtures thereof such as "Dowtherm" (Registered Trade Mark), tetralin and decalin.  The adsorbate can readily be separated from the desorbent by vaporisation of the adsorbate without vaporisation of the desorbent, such as by flash distillation.  Using a cyclic process the cooled desorbent may be partially reheated by passing it through the hot sieve bed; the feed to be treated may alternatively be passed through without preheating, it being arranged that the final bed temperature is in the preferred range of 100 DEG -300 DEG  F. during adsorption.  During desorption, pressures of 1-100 p.s.i. may be used if desired and the sieve may be finally treated by reduced pressure or by a small amount of refinery purge gas at 200 DEG -600 DEG  F. to remove final traces of adsorbed normal hydrocarbons.  In a preferred continuous fluidised bed process (Fig. 2) a feed naphtha which may be a virgin naphtha or hydroformate enters by line 2, is heated to about 250 DEG  F. in heat exchanger 4 and enters the adsorption column 10 as a vapour by line 6.  The adsorbent enters the column by line 14 and flows downwardly, adsorbing n-paraffins.  The unadsorbed vapours leave by line 8 and may be partially recycled by line 14 to provide a "reflux".  The adsorbent passes to a boiler 22 which contains a liquid such as "Downtherm" heated to 200 DEG -600 DEG  F.  The sieves are desorbed and the desorbed n-paraffins are withdrawn by line 23. Desorbed sieves and desorbent are passed to separator 16 from which are withdrawn an adsorbent-free stream by line 18 to be recycled to the boiler 22 and a slurry which passes by line 15 to the heat exchanger 4 and thence by line 17 to vessel 12 to which are also supplied non-normal hydrocarbons from the condenser 11.  In vessel 12 the adsorbent settles through an upflowing stream of isoparaffins which displaces the desorbent and replaces it as the carrying agent. An adsorbent-isoparaffin mixture passes to the column by line 14 and an isoparaffin-desorbent stream passes to the still 30 by line 13. In the still the desorbent is separated and recycled through furnace 26 to boiler 22 and isoparaffins leave by line 31.  The adsorption may also be effected with the feed in the liquid phase.

Title: Rubberless elastic fabric
IPC: D03D15/56
Filed: 1929-07-31
Abstract: 316,589. Elastic Weave Products, Inc., (Assignees of Dorsky. H. P., and Lawton, O. S.). July 31, 1928, [Convention date]. Materials, special.-In the production of rubberless elastic fabrics, attachable as neck. waist, and leg bands to knickers, trousers, pyjama trousers, &c., blouses, shirt waists, jackets, &c., dust caps, hats bonnets, portieres, draperies, lamp shades, chair and couch covers, shoes, &c., the yarn, preferably cotton of good grade and of long staple, is given an extremely tight twist, far in excess of that ordinarily used. In a 24/2 ply yarn, 40-50 turns per inch length are suitable, and the finer the yarn the greater the number of turns. Before weaving, the yarn is then conditioned or set by moistening and drying while under tension. This can be done by winding on bobbins directly after twisting, then steaming and drying the bobbins of twisted yarn. The dried set yarn is then either warped and made into fabric or it may be used as thread or cord. The yarn or the fabric obtained therefrom may have its elastic properties developed at any time by immersion in water and drying. Fig. 1 shows a fabric comprising overtwisted and set warp threads 20 and ordinary wefts 21, Fig. 5 shows the effect of moistening and drying, the fabric having shrunk to half its width and the threads 20 assuming a spiral or spring-like shape. Fabrics may be formed with the warp threads reverse twisted in alternate threads or alternate groups of direct and reverse twist warps may be used. The over-twisted yarn may be used for either the warp or the weft or it may be used for both, thus preventing elasticity in both directions and making possible the production of fabrics having squares, circles, and other geometrical figures of elastic or non- elastic material. Yarns of silk, wool, and linen may also be used

Abstract: 277,363. Frova, G. Sept. 10, 1926, [Convention date]. Addition to 247,592. Removing stones and stalks from fruit. - The machine for removing stones, cores, and stalks from fruit described in the parent Specification is provided with means for properly distributing the fruit to the gripping-members 25, said means comprising a revolving dish 5 on which the fruit is heaped, the dish having holes 161 arranged in groups adjacent its periphery, each group being registered at times with the upper ends of tubes 11 leading to the gripping-members 25 on the drum 22. The holes 161 are opened and closed at the requisite times by a cam-operated reciprocating plate 151 and the bottoms of the tubes 11, which are received in a straight header 13, are opened and closed by a sliding plate 186 having a resilient connection with links 187 &c. connecting it to an operating cam. The stalks are gripped by plate-like members 92, 92<1> havng notched edges and being moved towards or away from one another by a cam slotted plate 213 pivoted at 207 and operated through links &c. from a cam shaft 20. The plates 92, 92<1> are situated over the gripping-members 25 and the movement of the plates, operating on the stalks, moves them to the vertical. After the stalks are gripped, the plates are raised by cam and link mechanism, and the stalks are pulled out of the fruit. A spring-pressed sliding bar 201 moves outwards when the plates 92, 92<1> are opened to eject the stalks, which action may be assisted by rotary brushes. Fruit, which becomes stuck in the tubes 11, may be forced through by flexible plungers of rubber or spiral spring mounted on the dish 5 and operated by cam and lever mechanism. Alternatively, air or water nozzles may be directed into the tubes to clear them of fruit. The dish 5 carrying the heaped fruit is revolved intermittently by ratchet mechanism operated by links from the cam shaft 20, each movement bringing a fresh group of holes 161 into registration with the tubes 11. The dish 5 is locked between each movement by a sliding bolt operated from the shaft 20. The fruit is prevented from interfering with those already in the holes 161 over the tubes by a curved bar 183 hinged to the rim 4 so as to be liftable, and carrying a brush 200 at its end. Other brushes 185 are hinged to the rim 4.
