Patent GB-786603-A (GB)
Title: Process for the catalytic cracking of hydrocarbon oils
IPC: C10G11/04
Filed: 1956-01-16
Abstract: Hydrocarbon oils are converted into gasoline by contacting the oil under cracking conditions with a physical mixture of an active cracking catalyst and a microporous silica gel having an available surface area of at least 300 square metres per gram of silica gel, the proportion of silica gel in the mixture being such that its available surface area in the mixture is between 2 and 8 times the available surface area of the active catalyst.  The physical mixture may be produced by mixing the powdered cracking catalyst with powdered silica gel, or by mixing pellets of the cracking catalyst with pellets of silica gel.  In an example, a West Texas flashed distillate having a middle boiling-point of about 350 DEG  C. was cracked in the presence of a silica/alumina catalyst, having a specific surface area of 100 square metres, mixed with silica gel of specific surface area 750 square metres, the proportion of the two components being such that the ratio of the silica surface area to the catalyst surface area was 5.  Both the catalyst and the silica gel were in the form of particles which passed a 100-mesh sieve.  The particles were maintained in the reactor as a fluid bed at a temperature of 500 DEG  C.  The yield of gasoline produced was 33.4 per cent by weight of the feed charged.  The octane number of the gasoline (after addition of tetraethyl lead) was 99.

Title: Process and apparatus forthe manufacture of slub yarns
IPC: D02G1/16
Filed: 1973-01-11
Abstract: 1424771 Making and finishing yarns HOECHST AG 11 Jan 1973 [11 Jan 1972] 1585/73 Heading D1F In the manufacture of slub yarn from continuous filament or filaments (which may be in the form of a monofilament or a bundle or twisted or "twistless" yarn thereof) the filament is overfed into a zone wherein it is subjected to a transverse pressure difference so as to form an open loop therein, the pressure difference is periodically varied in such manner that the loop becomes closed, and subsequently the loop is united along its entire length with the filament to form a slub therein. The slubs may have a titre 3-4 times that of the starting filament and may differ in varied average length and/or distribution or be nearly the same length disposed at equal distance. The filament(s) may be of synthetic polymer e.g. a polyamide, polyethylene terephthalate or polyacrylonitrile. As shown, a continuous multifilament 1 is forwarded through a guide 2 and overfed by rollers 3 to a loop forming device wherein it passes through a funnel inlet 4 into guide tube 5 wherein it accumulates. Suction induced in a jet 7 (by feeding compressed air continuously through feeder tube 6) draws the filament in the form of an open loop through a blowing jet 8 into a connecting tube 10. Each time a gas stream pulse is introduced into jet 8, through feed tube 9 by means of a magnetic valve 11 controlled by an aperiodic pulse generator transmitting pilot pulses in random intervals of time the open loop is closed. The loop leaves jet 8, enters a cylindrical top 13, emerges through orifice 14 and passes over guide pins 15a and 15b to an interlacing jet 16 which is supplied with a gaseous medium through magnetic valve 17 in a predetermined time lag over jet 8 so that gas stream pulses striking the yarn interlace the formed loops with the continuous filament(s) and thus "set" them, the yarn sections between the slubs remaining in their original state, and the resultant slub yarn is withdrawn by means of a godet 18 and idler roll 19 and wound onto a bobbin 21. In a modified apparatus, Fig. 2 (not shown) an additional reinforcing filament or yarn for the slub yarn is fed into jet 16.

Abstract: 192,381. Sperry Gyroscope Co., (Assignees of Morgan, T. A., and Thompson, H. H.). Jan. 25, 1922, [Convention date]. Pneumatic actuation.-The motor for actuating the follow-up support or element of a gyro-compass is controlled by a pneumatically-operated switch, the action of which depends on differential air pressures set up when relative rotation in azimuth occurs between the sensitive and fol. low-up elements. In the form shown, the vertical ring 9 within which the gyro-casing 19 is pivoted, is supported by wires 7 passing through a hollow sleeve 5 forming part of the follow-up element 10, the sleeve being journaled by means of bearings 3, 4 within the spider 2, supporting the compass. The follow-up element extends downwardly in the form of the usual ring 14<1>, in which are provided bearings 19', 20 for the ring 9. The pneumatic means for controlling the follow-up motor 12 comprise a pair of tubes 25, 26 extending outwards in opposite directions from the interior of the sleeve 5 and terminating in nozzles, in the form of narrow vertical slots, co-operating with sectors 37, 37<1> carried by posts 38, 39 secured to the ring 9. Air is drawn inwards through the tubes 25, 26 and up through the sleeve 5 by a blower 29. Passing into the tubes 25, 26 are tubes 42, 42<1> with outwardlydirected ends 83, and these tubes communicate with bellows 43, 43<1>, Fig. 3, mounted on an arm 45 of the followup element, and provided with points 46, 47 bearing on the arms of a pivoted lever 48. The ends of these arms are formed as contacts 49, 50 co-operating with stationary contacts 51, 52 to complete the circuit of the reversible motor 12. In a modification, the blower is dispensed with, the air flowing in the space between the rotor and its casing being utilized. For this purpose the space between the rotor and the casing is restricted at a point adjacent one of the trunnion axes to produce the effect of a Venturi tube, whereby air is drawn in through the oppositely-directed nozzles and passes through an aperture in the ring 9 and thence enters the casing through an aperture in the trunnion.

Abstract: 947,860. Trap shooting. C. C. AFFLECK. May 23, 1961 [Feb. 21, 1960], No. 2164/60. Heading A6D. A clay pigeon trap comprises a pivotally mounted clay pigeon carrier arm, resilient means for resiliently loading the arm and readily releasable means for locking the arm in an initial position against rotation until releasing the clay pigeon and further resilient means for returning the arm to its initial positions means being provided for causing the resilient means resiliently to load the arm after the arm has been locked in the initial position against rotation. A clay pigeon carrier arm 11 is mounted on a pivot rod 10 on a plate 1 adjustably supported on brackets 2, 3 on a table 6 mounted on a tripod. The arm 11 is loaded by a spring 18 which extends between a bar 16 pivoted to a cross bar 15 on a bracket arm 14 extending from the plate 1 and a lever 12 pivoting on the rod 10. A further restoring spring 33, tensioned when the arm 11 rotates through an arc of a circle, extends from the lever 12 to a bracket 31 on an arm 29 on the plate and passes round an intermediate roller. The arm 11 is locked by a spring loaded rod 39 slidably mounted in supports and having one end engaging a latching plate under the carrier arm. The rod is actuated by a lever 42, pivoted to one end of the rod and to a bracket on the arm 14, to displace the rod against the action of a spring 45 so that the carrier arm is free to rotate under the action of the tensioned spring 18 until arrested by a stop 30 on the arm 29. A lever 22 is rotated to release a roller 26 on a lever 25 on the plate 1 from bearing against the bar 16 to free the bar and enable the arm to be reset. The spring 18 is then tensioned by restoring the lever to its initial position with the roller 25 bearing against the bar 16. An electromagnet may control the release mechanism, then the means for locking the carrier arm against rotation comprises a pivotally mounted bell crank lever one arm of which engages with the carrier arm to prevent rotation thereof and the other arm engages a spring loaded slidable bar which is urged to move to cause the lower arm to release the carrier arm and is restrained against movement until an electromagnetically operated device is actuated to release the slidable bar. Mechanical means such as a rope or linkage may be used to rotate the bell crank lever to the carrier arm release position.

Title: A method or process and machine for cutting bevel or conical gears
IPC: B23F5/20
Filed: 1930-01-22
Abstract: 338,436. GÚny, A. J. Jan. 22, 1929, [Convention date]. Gear-cutting.-In cutting bevel gears by means of a cutter F, Fig. 4 having straight sided teeth arranged along part of a single turn of a helix and rotated continuously in timed relation with the blank, while it is fed along a generator of the blank root cone, the teeth are generated to correct involute profile by superposing on the blank rotation an oscillating rolling generating movement and simultaneously imparting the corresponding generating movement to the cutter, by oscillating it about the imaginary basic crown wheel axis during its feed movement. Equations are given in the Specification for determining the value of the angle #, Fig. 3, the pitch of the helix of the cutter teeth, and the pressure angle of the teeth. In a machine for carrying out the invention the guides 1 of the tool carriage are mounted on a rotatable head 2 and are pivoted at 2<a>. The oscillatory generating movement of the tool is effected by worm gearing 3 operated from a reversing mechanism 6. The blank table 4 is adjustable to the required cone angle about an axis 5<a> and is driven from a shaft 10 through differential gearing 9. The shaft of the worm 3 is connected through change gears 7 and worm gearing 8 to the casing of the differential, thus giving the required generating movement to the blank in unison with the tool head oscillations effected by the worm 3. The invention is also applicable to the cutting of helical bevel gears. Since a straight sided cutter is used, the same cutter may be employed to cut blanks having different extreme modules.
