Title: A process of hydrocarbon oil conversion
IPC: C07C9/14
Filed: 1937-03-08
Abstract: <PICT:0484527/III/1> In cracking process of the kind in which oils are cracked in the vapour phase by admixture with hot carrier gases, the residual gas, after separation of motor fuel fractions, is compressed, subjected to absorption with oil to separate lean gases, comprising chiefly hydrogen and methane and ethane, from rich gases which are absorbed, the lean gases being returned to the conversion cycle while the enriched oil is distilled to remove the rich fraction which is then subjected to polymerization with the recovery of a polymerized product suitable as a motor fuel. Crude oil is heated in a coil 14 and passed into a flash drum 15 where it is vaporized and mixed with the carrier gases from a line 62.  The mixture is heated to 950-1050 DEG  F. in coils 10 and passed into a soaking chamber 21 where the cracking reaction is completed.  The products pass to a fractionator 23 from which heavy residue is withdrawn through a line 24 and through which an intermediate fraction is recycled through lines 28, 26 and a heat exchanger 27.  Products in the gaseous state pass off through a line 32 through a cooler 33 to a receiver 34 where the gasoline product is separated and used in part as reflux for the tower 23. The gases are then compressed in a compressor 40 and passed through a cooler 41 to a receiver 42 where liquid components are separated.  The gases pass to an absorption tower 44 through which a suitable absorption oil, e.g. a heavy gasoline condensate, is circulated from a line 46a  The absorbed lean gases are evacuated through a line 61 while the rich gases are absorbed in the oil which is passed to a still 48 under pressure from which any unstable light fractions are removed and thence with reduction of pressure into a still 50 where the rich gases are boiled off, the stripped oil being recirculated to the line 46a.  The rich gases are compressed by a pump 53 and passed to a coil 52 where they are polymerized under a pressure of about 3000 lb. per sq. inch, the products passing through a cooler 55 to a receiver 56 where the liquid components are collected the gaseous products being recycled through a line 57 to the absorber 44.  The lean gasses passing off through the line 61 are recycled in part as the carrier gas to the line 62.

Abstract: 592,064. Hat-pouncing machines. DORAN BROS., Inc. March 26, 1945, No. 7538. Convention date, April 12, 1944. [Class 63] In a pouncing machine for operating on hat brims, the hat block is rotated on a horizontal axis and is oscillated transversely of the axis. It is carried above a pair of pouncing pads, which engage opposite sides of the brim, by a floating frame, so that the pads support the hat and the latter can be lifted clear of the pads. The pads are carried by springs and are vibrated in arcuate paths lengthwise of the brim. The hat block 4 is mounted on a rotary shaft 10 carried by arms 14 pivoted on a shaft 17 mounted in arms 18 fast on a rockshaft 20. The block is rotated from a driving shaft 28 through chain gearing 40, 44, 48 and is given a timed oscillation by a cam 32 on the shaft 28 acting on a cam lever 22 fast on the shaft 20. The pouncing pads 50 are arranged beneath the block 4 so that the floating block assembly is supported by the right-hand pad. The pads are carried by leaf springs 54 on rock shafts 62, which are oscillated in opposite directions by cam levers 70 and a vertical cam shaft 76 driven by a pulley 77. The right-hand shaft 62 is mounted so that it can be swung by a hand lever 89 to move its pad away from the other pad to permit the insertion of the hat brim between them. It can be locked in open position by a catch 93 and is biassed by a spring, adjustable by a worm shaft 104, so as normally to hold the pads together. In operation, with the shaft 28 and pulley 77 running, the righthand pad is swung to the right, the shaft 10 is .raised by hand, and a hat on its block is placed in position. The shaft 10 is lowered and the right-hand pad released. The hat is then rotated and oscillated transversely to compensate for its oval shape, and the pads are vibrated rapidly in contact with the brim; the spring-mounting 54 causing the vibration to be whippy.
