Title: Improvements relating to the separation by distillation of components of a mixture of hydrocarbons
IPC: C10G7/02
Filed: 1938-07-27
Abstract: 517,440. Stabilizing crude petroleum. RUTHRUFF, R. F. (Kellogg Co., M. W.). July 27, 1938, No. 22375. [Class 32] Crude petroleum oil is stabilized without excessive loss of butane at temperatures and pressures below which corrosion of the plant occurs (i.e., below about 540‹F. and 200 lbs. per sq. inch) by admixing butane with crude to be stabilized in such an amount that on fractional distillation of the mixture a propane free bottom product is obtained containing a large proportion of the original butane content and such that the added butane will suffice for refluxing, fractionating the mixture into a stabilized substantially propane free bottom product and vapours containing butane, recovering the butane and adding it to additional crude to be stabilized. The butane is preferably recovered by absorption in an absorbing oil which is then added to fresh crude to be treated. According to the amount of butane desired to be recovered, three types of absorber oil are used (1) unstabilized crude (2) stabilized crude (3) stabilized crude which has been flashed at reduced pressure to debutanise it. Crude petroleum is fed through hear-exchanger 5 and mixed with absorber oil from line 7 is fed through line 8 into stabilizing tower 9 heated by steam coil 10. The top of the tower is cooled by a coil 11 to condense part of the butane driven off and return it as reflux. The remaining gases and vapour pass off through line 12 to the absorber unit to which absorber oil of the type required is fed, i.e., (1) crude unstabilized gasoline through line 3 (2) stabilized gasoline, withdrawn from tower 9, through lines 15, cooler 16, and line 18 (3) debutanized crude obtained by diverting a portion of the stabilized crude through line 19 and flashing it in a low pressure zone 20 is fed through heat exchangers 22, 24 and line 27 to the tower 13. The enriched absorber oil is removed through line 37 and recycled to mix with the crude in line 7. Vapours obtained by flashing in zone 20 are cooled in cooler 31 and the condensate compressed and returned to the absorption tower through line 34. The absorber oils are fed through line 28, 29 to the top or middle of the tower 13.

Title: Improvements in or relating to mineral coated paper
IPC: B05C1/08
Filed: 1931-08-10
Abstract: 379,833. Mineral-coated paper; coating webs. POTTS, H. E., 12, Church Street, Liverpool.-(Champion Coated Paper Co. ; Hamilton, Ohio, U.S.A.) Aug. 10, 1931, No. 22534 [Classes 96 and 140.] Paper, postcard, cardboard in a wet condition is coated by applying an aqueous mixture of at least 2/3 clay, satin white, blanc fixe and the like and not more than 1/3 casein, starch, glue and the like to the moving paper &c. or to an intermediate moving surface and removing the excess mixture by a doctor surface which is continuously cleaned and which moves in the opposite direction and at a speed above that at which the coating is ridged and below that at which it is frothy. The paper P, which has been moistened by steam &c. or by prior application of excess coating, passes over a roller A and excess coating C is removed by a doctor roller D, which is scraped by a doctor W of rubber, soft metal, &c., the coating C being supplied by a pipe. The rollers A, D are of non-absorbent material, e.g. steel and are in clockwise rotation. At low speeds of the roller D ridges are produced in the coating, and as the speed increases relative to that of the paper the ridges become less pronounced and closer together, the coating then becomes uniform, then streaky, then wavy or rippled and finally smooth but frothy, the coated paper having a pinhole effect. Rippled coatings are thus produced for " art " papers. The nature of the effects varies with the speeds, the coating composition, the distance apart of the rollers &c., the ridges occurring when the doctor speed is 1/7 and the ripples when it about equals that of the moving surface. In examples for paper speeds of 100 and 500 ft. per min., the ranges of doctor speeds for smooth coatings are 40 to 72 feet per min. and 136 to 214 feet per min. respectively. In alternative forms the roller A or the roller D is substituted by a travelling band or the coating is applied to the surface of the roller A and wiped off by the paper web which contacts with its surface and moves in the opposite direction.

Abstract: 977,016. Forage-harvesters. A. SERIGSTAD, and T. SERIGSTAD, [trading as SERIGSTAD MASKINVERKSTED]. June 22, 1961 [May 27, 1961], No. 22588/61. Heading A1F. Relates to a forage-harvester of the type having an upper part B rotatable relatively to the delivery shoot A and a discharge spout C adjustable on the end of the part B by means of a cable 13, the part B being movable over a toothed ring 2 on the upper end of the shoot A and being securable relatively to that ring. According to the invention a single shaft 21 terminating in a hand-wheel 1 effects both adjustments, the shaft being rotatable to wind or unwind the cable 13 on a pulley 7 and being bodily movable to swing the part B about the axis of the toothed ring. The ring 2 is in contact with a plate 11 secured to the bottom of the part B, the shaft 21 being mounted in a sleeve 22 carried by a holder 8 pivoted on aligned studs 18 on the plate 11 and the part B. A stud 9 on the shaft 21 locks the shaft to a detent formed by apertures 10 in the plate 11. Pivoted pawls 3 securing the plate 11 to the ring 2 can be overridden by applying lateral force to the shaft 21. Axial force applied to the shaft will disengage the stud 9 and allow the shaft to be re-positioned on the detent at a more convenient position for the user. A spring loaded clutch 6, 14, 15 prevents the returnspring D on the spout C from unwinding the cable 13, but the clutch can be overridden by rotation of the hand-wheel 1.

Title: Improvements in or relating to hydraulic tracer valves
Inventor: WEAVER PAUL JOSEPH
IPC: B23Q35/36
Filed: 1965-05-28
Abstract: 1,103,834. Copy-milling. TRUE-TRACE CORPORATION. 28 May, 1965, No.22889/65. Heading B3K. An hydraulic tracer comprises a spool valve controlled by a stylus 31 having three spherical or ball portions 32, 33, 34 by means of which it is adjustably mounted. The tracer has three valves 22, 23, 24 at right-angles to each other. The ball 32 is confined between seatings in a sleeve 50 adjustable axially by a threaded collar 58 and a sleeve 55 adjustable axially by a screw 41, the sleeves being urged apart by a spring 62. A flexible boot 64 seals the lower tracer opening. The second ball 33 is embraced by yokes connected to the valves 23, 24, one of the yokes having a gib and screw adjustment 72. The construction is similar to that described in U.S. Specification 2,753,145. The extent of angular movement of the stylus and hence the rate of movement produced in a machine by the valves 23, 24 is determined by the setting of a bevelled ring 81. The ring 81 can be axially adjusted by a lever 86 and an eccentric engaging a sleeve 87 to control the degree of engagement of the edge of the ring in a bevelled groove in a sleeve 100. The third ball 34 is recessed to accommodate a free ball 106 engaging the axially-movable spool 101 of the valve 22. Upward movement is limited by a rod 107 adjusted by a nut 111. The spool 101 is angularly adjustable to control the rate of flow. The rod 107 can be moved to one position such that upward, but not tilting, movements of the stylus cause upward movement of the spool 101 since the ball 106 rides on a plate 109: and to another position, Fig. 2, where both tilting and upward movements are effective to move the spool 101. In operation for 360 degrees copying, the seatings for the ball 32 are adjusted to prevent axial movement thereof and control is through the valves 23, 24. For co-ordinated control, the single valve 22 is used, a groove 134 being then in circuit. According to axial movements of the spool 101, so one or other of two fluid-pressure motors is supplied with pressure from a line 121 and a groove 128. At the same time, exhaust from a motor being operated is controlled or cutoff by a further portion of the spool co-operating with a groove 134. For 3-D copying using the three valves 22, 23, 24 the ball 106 contacts the plate 109, and the connections to the groove 134 are inoperative.

Abstract: 320,711. Triggs, W. W., (Williams Oil- O-Matic Heating Corporation). Aug. 10, 1928. Electrically controlling fuel and air supplies.- In a liquid fuel burning apparatus in which the circuit from the mains 8, 9 to an electric motor 2 driving a pump for supplying fuel to the burner nozzle 5 and a fan for supplying air to form a combustible mixture includes a manually operated switch 17, a boiler' or pressure operated switch B, a room thermostat T, and a stack control device S, the stack control device S comprises two mercury tube switches 28, 29 operated by a bimetallic spiral arranged in the stack, one switch being opened when the other is closed. When, on the operation of the thermostat T combustion is to be started, the circuit to the motor 2 is made through the switch 28 and a safety switch 21 and ignition is effected at the burner nozzle by the secondary current from a transformer 11 having a switch 14 arranged in its primary circuit. Should ignition not take place a thermally operated device 26 releases the mercury tube 25 of the switch 21 to break the motor circuit after a predetermined time. Normally ignition ensues and, before the operation of the device 26 takes place, the bimetallic spiral operates to break the motor circuit at the switch 28 and to re-make it through the switch 29 and a switch 31 carried by a pivoted arm 15. The arm 15 also carries the ignition switch 14 and, when the motor is not in operation, is in such a position that the switch 14 is closed and the switch 31 is open. When the motor is in operation the pressure in the burner atomizing chamber acts through a pressure device 16 to raise the arm 15 thereby closing the switch 31 and breaking the ignition circuit by opening the switch 14.
