Patent GB-474567-A (GB)
Title: A process for producing gasolines of a high anti-knock value
IPC: C10G61/06
Filed: 1937-03-17
Abstract: Highly anti-knock gasolines are obtained by subjecting naphthene-containing gasolenes to catalytic dehydrogenation and then to extraction with selective solvents for aromatics.  The raffinates may be re-treated, or may be used as motor gasoline of lower anti-knock value, or be given a higher anti-knock value by dehydrogenation, or by cracking to gaseous olefines which are then polymerized.  The initial material may first be refined to remove substances poisonous to the dehydrogenation catalyst, e.g. by treatment with aluminium chloride or sulphuric acid or solvents. Solvents specified are liquid sulphur dioxide, furfural, nitrobenzene, nitromethane, and "Chlorex" (Registered Trade Mark). In an example, Sumatra gasoline is passed over a tungsten catalyst at 500 DEG  C. under a hydrogen pressure of 50 atmos. whereby the aromatic content is increased from 25 to 43 per cent; it is then extracted with 2 vol. of liquid sulphur dioxide at -15 DEG  C.; the solvent-free extract contains 71,5 per cent of aromatics.

Abstract: 797,657. Fuel-injection systems. SOC. INDUSTRIELLE DE BREVETS ET D'ETUDES S.I.B.E. March 12, 1957 [March 26, 1956], No. 8150/57. Class 7(3) In a fuel-injection system having a nozzle 19 in the cylinder or intake pipe fed by an injection pump 4 which is supplied from a reservoir 2 by a feed 1, a by-pass 25 around the injection pump 4 is opened at cold starting under manual or automatic control to permit fuel to be fed to the engine directly from the feed pump 1. The by-pass 25 has one branch 26 connected to the outlet pipe of pump 6 and containing a normally closed spring loaded valve 29 and a second branch 28, containing a normally open valve 30, leading to the inlet of pump 1. Actuation of a rod 38 at cold starting rotates a lever 16 to hold throttle valve 12 slightly open and rotates a lever 37 to increase the spring load on valve 30, thereby preventing it opening, whereby when the engine turns over the delivery from pump 1 flows directly through valve 29 to the nozzle 19. When the rod 38 is released at normal running, the valve 30 opens to by-pass part of the delivery of pump 1 through pipe 28 to the pump inlet and pipe 29 closes due to the increase in pressure in pipe 6. The by-pass 25 may lead to a separate nozzle and the delivery of pump 4 is controlled by a suction responsive device 23. In a modification the levers 16 and 37 are controlled automatically by a bi-metallic element.

Title: Improvements in delivery mechanism for cigarette making machines
IPC: A24C5/32
Filed: 1930-03-14
Abstract: 345,484. Cigarette-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(American Machine & Foundry Co.; 511, 5th Avenue, New York, U.S.A.) March 14, 1930, No. 8325. [Class 130.] Cigarettes are delivered in an orderly manner from a cigarette-making machine by a collector having a series of pockets which are rotated to bring them into axial alignment with the oncoming cigarettes, and are then moved through an inclined position to the delivery position to enable the cigarettes to move lengthwise in the pockets and bring their ends into alignment. Bands 54, 55 are driven faster than the cigarette rod to separate the cigarettes C and propel them into pockets formed by strips 21 on a conical drum 20. As the drum rotates the pockets on the underside of the cone are brought into axial alignment with the oncoming cigarettes. The bands 54, 55 are driven through gearing from the main shaft 29, which also rotates the drum 20 and drives a belt 9 at approximately the same speed as the peripheral speed of the cone in the middle. Thus there is no tendency for the cigarettes placed on the belt 9 to rotate. The cigarettes are held in the pockets by cone-shaped guards 78, 79. The guard 78 is forked and one of the arms of the fork forms the flap 81, which projects under the transfer belt 55 to receive the cigarettes from the machine. As the drum revolves, the cigarette slides under gravity towards the apex of the cone. Alternate cigarettes are stopped by a disk 82 or a series of stops 83, so that in the case of tipped cigarettes they are lined up in rows with the tips all pointing the same way. After a complete revolution, they are guided by flaps to the discharge belt 9. Shorts fall into the shoot 86. For collecting oval cigarettes, the guards 78, 79 are so close that they prevent rotation of the cigarettes, and the printed sides after delivery all face the same way.
