Title: Improvement in method of coking hydrocarbons
Filed: 1934-11-17
Abstract: <PICT:0452491/III/1> In a process for distilling and coking hydrocarbon oils, the oils are flashed and fractionated, preferably under vacuum, in a flashing tower, the required temperature being maintained by continuously drawing off a fractionated side stream from the tower, and returning it thereto after heating it to above 455 DEG  C. and the pitchy residues collecting at the bottom of the tower are fed into a coking chamber and coked.  Fuel oil, introduced through a pipe 11, is fed alternatively through lines 13, 13a into a flashing tower 14.  A condensate collected in a tray 26 is passed through a line 29 into a pipe still 47 where it is heated to 455 DEG C. and then returned to the tower through a line 48 in admixture with the feed from the line 13a.  Light vapours pass off at the top of the tower through a line 15 to condensation and collection. The heavy residues are withdrawn through a line 49 and passed, optionally through a coil 55 heated by waste gases, and then through lines 61, 62 into the coke ovens 44, 45 to cool the gases evolved in the coking or in part through the pipe 54 into a flashing tower 37.  The residues are coked in the ovens 44, 45, and the vapours evolved pass through off-takes 42, 43 and a main 65 into the flashing tower 37. Vapours from the tower 37 pass through a line 66 into the tower 14 while residues are recirculated through a line 76 to the tower 14 or directed through lines 68, 71, 73, 41, 40 to flush out the main 65 and off-takes 42, 43.  Part of the condensate in the line 29 may be directed through a line 34 into the tower 37 or into the off-take 42. The towers 14 and 37 may be combined in a single unit.

Title: Synthesis of ethers of vitamin a
Filed: 1947-12-16
Abstract: Process for the synthesis of ethers of Vitamin A starting from an aldehyde of formula B.CH.Me.CHO and a ketone of the formula CH3.CO.CH2.CH2.OR in which formul  B and Me represent respectively methyl and the radical of which b -ionone is the methyl ketone, and R stands for alkyl (including aryl-substituted alkyl), said process comprising converting either the aldehyde or the ketone into the corresponding acetylenic carbinol and thence, with or without first dehydrating the carbinol, into the Grignard or metallo derivative, which is then condensed with the other of said starting materials and the product finally, in either order, hydrogenated to reduce the acetylenic to an ethylenic bond and dehydrated.  The final dehydration step may be effected by means of phosphorus tribromide, and dehydrohalogenating the product.  Either or both the dehydration steps may be effected by means of p-toluenesulphonic acid or aluminium phosphate.  The final hydrogenation may be effected by means of hydrogen in the presence of palladium black.  Detailed examples are given.  Specification 649,339 is referred to.

Title: Improvements in counting devices particularly for textile goods
IPC: G06M1/08
Filed: 1930-11-05
Abstract: 358,324. Counting-apparatus ; zeroizing mechanism. AMMON, E. R., 1401, N. 12 Street, Reading, Pennsylvania, U.S.A. Nov. 5, 1930, No. 33282. [Class 106 (i).] A counting device for textile goods such as hosiery comprises a lever depressed by the goods and actuating a numeral drum which causes the locking of the lever when a predetermined count is reached. If the lever is raised at any time the drum is returned to zero by means of a spring. The articles to be counted are placed in a hookshaped arm 10 and on entering the same depress a lever 14 operating the counter 12. The apparatus is attached to a bench by a clamp 15 and may be pivoted into any required position, and then locked by a nut 16. The lever 14 is pivoted at 18 and is maintained in a horizontal position by a spring 19. It has pivoted to it at 29 a lever 28 the end of which consitutes a pawl engaging with ratchet teeth 25 on the inside of a numeral-wheel drum 20. The outer periphery of the drum is provided with numerals viewed through an opening in the casing. A retaining pawl 31 is held in contact with a second set of teeth 26 on the inside of the drum by a spring 35. When the full number of articles has been counted a lug (not shown) on the drum contacts with a projection on the casing and further downward movements of the lever 14 are prevented. At the same time a lever 44 slips over the end of a cam 47 secured to the drum shaft and causes a hammer 40 to strike a bell 17. To zeroize the device the lever 14 is moved upwards thereby moving the pawl 28 to the left. A cam surface 50 on the pawl then engages a pin 51 and lifts the pawl off the teeth 25, the top of the pawl at the same time engaging and lifting the retaining pawl 31. The drum then returns to zero under the action of a coil spring, the lug and projection previously described forming a zero stop. To prevent more than one step being given to the drum at each actuation of the lever 14, the edge 53 of this lever engages, towards the end of its movement, with a pivoted member 52 which is thereby forced into contact with a pin 54 on the retaining pawl 31 and so locks the latter in engagement with the teeth 26.

Classes 99(1) and 99(2) In a method of making. a hose 10, Fig. 1, for a pinch valve having rubber sealing rings 19, 20 at each end thereof, a tube 11 provided with a braided reinforcement 12, e.g. of cotton, nylon or rayon, and mounted on a mandrel has an outer jacket 13 applied thereover and sealing rings are substituted for annuli 49, Fig. 6, removed from the tube- The hose is cured to form an integral structure. The tube 11 and jacket 13 may be of natural or synthetic rubber, and any desired number of layers of braid orjackets may be applied either successively or alternately to form the hose. As shown in Fig. 1, the hose incorporates a portion 14 of an internal diameter equal to that of the bore of pipes 21, 22 connected by the hose. Initially, the tube 11 is extruded and assembled on a mandrel having a diameter equal to that of the internaldiameters of the portion 14 and pipes 21, 22, and one or more layers 12 of braid are applied to the tube, the strands of the braid making an angle of 30 to 45 degrees with the axis of the tube In the second stage of making the hose, the tube is expanded by air pressure and passed over anothermandrel 24 built-up from sections 25, 31 -having reduced stem portions 27. Upon release of the air pressure, the tube contracts at the portions 27 of the mandrel to form the portions 14. The jacket is expanded by air pressure passed over the tube and allowed to contract by release of the air pressure, whereafter the mandrel is mounted in a lathe and rotated to enable the annuli 49 to be removed and the resulting channels to be filled with ribbons of uncured rubber to form rings. After helically wrapping the hose with tape, curing the hose, and removing the tape, the mandrel is again mounted in the lathe and the rings are centrally cut through to produce the sealing rings 19, 20. As shown in Fig. 6, several hoses are simultaneously made.

The plates 5 are formed with recesses 24 to allow movement of the arm 8. The article is then moved downwardly by a plunger 25 into a delivery stacker formed by a front plate 37, the brush 12 and side brushes 40, the upper, rearwardly-extending portion of the wrapper being folded down by a blade 28, 34 carried by the plunger (operation G), and the lower portion being folded upwardly by the support 7 as it yields to allow passage of the article (operation 4).
