Title: Improvements in or relating to the refining of hydrocarbon distillates
IPC: C10G50/00
Filed: 1945-11-23
Abstract: Gasoline distillates obtained as the result of cracking operations are refined by contacting them with a catalyst comprising 0.1 to 10 per cent by weight of hydrous aluminium oxide supported on silica gel, under polymerizing conditions of temperature and pressure such that olefin hydrocarbons and sulphur-containing compounds are converted to compounds boiling above the gasoline boiling range, and then fractionating the effluent from the catalyst zone to eliminate these high-boiling products.  The gasoline distillates may be derived from thermal or catalytic cracking processes and may be clay-treated, for example by treatment in the vapour phase with fuller's earth, prior to contacting with the silica-alumina catalyst.  The refined gasoline distillates are useful as aviation gasoline blending stocks.

The frame carries a pin 14 disposed in a guide slot in the lever, and the lever carries a spring- biased cam follower 18 which co-operates with a cam disc 21 for oscillating the lever, the cam disc being driven by a pawl 24 carried by an arm 22 formed with a slot 28 adapted to engage the needle-holding screw on the needle bar, the frame being securable by a member 27 to the presser bar of the sewing-machine. The presser foot 32 is formed at one edge with a vertical wall 34, and at the other edge, which is inclined to the direction of work feed, with a needlepassing notch 35. The scroll member is carried by a plate 37 which is held detachably against wall 34 by means of a spring 41, a slot 38 provided in plate 37 being engaged by a pair of pins 39, 40 upstanding from wall 34. The scroll member comprises a vertical portion 42 secured to plate 37, a portion 43 which is bent laterally at the forward edge of portion 42, a portion 44 which curves downwardly from the upper edge of portion 42 and extends as a horizontal portion 45 beneath portion 42, and the guide member 46 which extends rearwardly from portion 44 and parallel to the inclined edge of the presser foot. As the material enters the scroll member it passes over portion 45 and its edge extends upwardly between portions 42 and 44, the roughened undersurface of presser foot 32 and the feed mechanism of the machine comprising to impart a zig-zag feed motion to the material. The upturned edge 50 of the latter slopes downwardly from the point of entry until it emerges substantially at the height of the upper edge of the guide member 46. The needle descends first in the notch 35 on one side of the guide member and then upon the opposite side of the latter to pass over the upturned edge 50 to effect an overedge stitch. The width of the stitch may be varied by the use of differently dimensioned scroll members. The stitch pattern may be varied by the use of a masking cam 29 which overlies the ratchet wheel 25 and is provided with deep and shallow notches 30 and 31 respectively. The deep notches permit the pawl 24 to engage the ratchet wheel, while the pawl when engaging the shallow notches will rotate the masking cam above and not the ratchet wheel.

Abstract: 244,778. Leon, K. O. Dec. 17, 1924, [Convention date]. Ball and roller bearings.-In an antifriction bearing in which the surfaces of the rolling bodies 3 and of one or both races have a curved generatrix, one or both race-rings 1, 2 have on the side opposite the race an annular groove 6, 7, and the width of the latter and the radii of curvature of the generatrices of the rolling bodies 3 and races are such that the axial extension of the contact surface between the race and the rolling bodies will be substantially equal to, or greater than, the width of the recess 6, 7, before the stress in the race-ring material reaches the elastic limit. Elasticity may be given to the rolling bodies 3 by axial holes 4 or end recesses 5, the former serving to accommodate spacing cage axles 10 shaped to permit selfalignment of the rolling parts. The length of the rolling body may be less than its diameter. The various radii of curvature may be such that the length of the line contact between the rolling bodies and races varies with the load without exceeding the elastic limit of the race-ring material. The bending stress in the race-rings is less than the stress in the surface of the races in contact with the rolling parts. The invention may be applied to ball bearings and to thrust roller bearings.

Class 112 [Also in Groups VIII and XXIV] In apparatus (see Group XXIV) for applying a seamless knitted pile fabric sleeve to the core of a paint roller, the sleeve S, Fig. 1, which is knitted with an inwardly extending pile 31 is first pulled through a rigid transfer tube and inverted on to the outside thereof by the pneumatic apparatus shown in Figs. 7-9 so that it assumes a radially - distended and longitudinally gathered condition with the pile extending outwardly; the transfer tube carrying the gathered sleeve S, Fig. 10, is then mounted on a fixed hollow mandrel 102 and the end of the sleeve is gripped by a pair of jaws 105 which pull it off the transfer tube on to an adhesivecoated roller core 32 as the latter is fed through the mandrel 102. In order to invert and gather the sleeve S on to the transfer tube 33, Fig. 7, the latter is mounted on a hollow mandrel 35 and the sleeve S is pulled into the mandrel by a pneumatically-actuated hooked rod 58. The end of the sleeve is then manually turned on to the outside of the tube 33 and is gripped by a pair of pneumatically-actuated jaws 34 which are reciprocated for a number of short strokes parallel to the mandrel axis in synchronism with opening and closing movements so that the sleeve S is pulled through and gathered on to the outside of the tube 33. The jaws 34, Figs. 8, 9, are pivoted in a housing 40 which is reciprocated in channels 41 extending parallel to the mandrel 35 by means of a pneumatic cylinder 38. The jaws are opened and closed by the bevelled end 51 of the piston rod of a pneumatic motor 50.. The motor 50 and cylinder 38 are controlled by respective valves 53, 54 each having two solenoids actuated by momentary closing of respective microswitches. The jaw-closing valve 53 is controlled by microswitches 60, 61, actuated by the housing 40 at the end of its stroke; the housing - moving valve 54 is controlled by microswitches 63, 62 actuated by a rod 56 on the piston rod end 51. An adjustable timer is incorporated in the circuit controlling the valve 53 so that once a manual switch has been actuated the jaws automatically undergo a sequence of,. say, six operations in each of which:-(1) the jaws are closed to grip the sleeve S (2) the housing 40 is moved to the dotted line position, Fig. 8, (3) the jaws are opened, (4) the housing 40 is returned to the full line position. If the stroke is eight inches such a sequence would gather a forty-eight inch sleeve on to the tube 33, which may be, say, eighteen inches long.
