Title: Method for controlling a fluid catalytic cracking riser
IPC: C10G11/18
Filed: 1973-01-10
Abstract: 1417315 Cracking GULF RESEARCH & DEVELOPMENT CO 10 Jan 1973 [10 Jan 1972] 1280/73 Heading C5E In the fluidized catalytic cracking of a hydrocarbon oil higher than gasoline, using a re. generated catalyst, at an inlet temperature between 593‹ and 792‹ C., an outlet temperature between 482‹ and 593‹ C. and a residence time less than five seconds, the yield of gasoline is changed by increasing the temperature of the regenerated catalyst and simultaneously adjusting the ratio of catalyst to oil, so that the outlet temperature is unchanged. This enables one to change the yield of a higher fraction, e.g. furnace oil, to suit seasonal demand, without much change in the quality, e.g. octane number, of the gasoline.

Title: Improvements in closures for bottles and other receptacles
IPC: B65D41/42
Filed: 1924-01-28
Abstract: 224,129. Carvalho, L. R. N. Jan. 28, 1924. Capsule closures; stoppers, screw.-A closure for bottles &c. comprises a top G, Fig. 1, carrying a packing-disc 5 and secured to a marginal flange H, Fig. 2, the lower portion of which is scored at 8 to form a detachable strip 9 spun beneath a shoulder 1 on the bottle to secure the closure thereto. The junction 3 of the top G and the flange H lies beyond the circumference of the bottle mouth and forms an upwardly extending rib 4 to which pressure is applied to force the closure on to the bottle against the resilience of the top G. The flange H is formed from a plain or ornamented metal sheet having its ends 13, 16 between the top and the score 8 bent over to adapt them to engage with each other and constitute the seam 2 when the sheet is bent to form a cylinder, the lower portion 9 being formed with a tongue 10 separated from the upper portion by a slit 11 to prevent the strain of the removal of the strip from being too close to the seam 2. The seam may be strengthened at its lower end by providing the flange with a bead 36, Fig. 15, and, by locating the score 8 on the underside of the bead, any jagged edge left when the strip 9 is torn away is turned towards the bottle .and thereby rendered harmless. At the lower end of the seam, the bent-over ends may be pressed into close contact with each other to strengthen the joint but they make loose contact only and so permit the flange to expand slightly to adapt itself to a tapered neck. The finished closure is varnished all over to prevent rusting. When the strip 9 has been torn off by pulling the tongue 10, the device acts as a temporary closure. To adapt the closure to screw-threaded bottles, threads may be moulded in the flange H.

Title: Improvements in mechanism for moving a body in a circular or elliptical path
IPC: B06B3/00
Filed: 1930-01-23
Abstract: 349,441. Sifting-apparatus, SCHIEFERSTEIN, G. H., 132, Wilhelmstrasse, Berlin. Jan. 23, 1930, No. 2336. [Class 117.] In mechanism for moving a body such as a coal screen in a circular, elliptical or like closed path, the body is actuated by a crank or eccentric and is subject to the controlling force of elastic means which have an initial constraint about the stroke of the crank. The elastic means store a constant potential energy which is independent of the speed. In the coal screen shown in Fig. 3, screens M<1>, M<2> are driven in a horizontal circular path by cranks 9 from a shaft 7 carrying a belt pulley 11. The screens are joined at their four corners by four coupling rods 3 carrying washers 4 on each side of which are rubber rings 5 which supply the elastic control and are initially and constantly constrained to a value corresponding to the full amplitude of the movement. The arrangement is such that as the speed increases, centrifugal force on the screens progressively replaces the elastic controlling force and finally sets up a reactional force of opposite sign. The screens are balanced by masses m<1>, m<2> and if desired, the drive from the shaft 7 to the lower screen may be omitted, or a single screen only may be provided. An elliptical movement may be generated by use of a loose coupling in the drive such as is described in Specifications 188,633 and 237,934, [both in Class 80 (iii), Linkwork &c.]. Alternatively the cranks 9 or screens M<1>, M<2> may be provided with radial slots in which the crank pins may move. The screen may be constructed so that it may be tilted about its axis of gravity and its angle of inclination may be read off on a scale. In another arrangement a box containing two superposed screens is driven in a vertical plane by a horizontal shaft 5, Fig. 7, passing through the axis of gravity of the screen and having eccentric driven ends bearing in the fixed side-plates 6. The fixed side-plates also carry bars 4 passing through rubber-filled bearings 3 in the screen. Eccentric balance masses 8 are provided. The part of the shaft 5 within the box is protected by a tube 9. The elastic material may be a flexible metal, tombac, steel or rubber.
