Filed: 1972-03-22
Abstract: 1382667 Hydrogenating aromatic hydrocarbons SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ NV 22 March 1972 13374/72 Heading C5E Aromatic hydrocarbons are hydrogenated over a supported catalyst comprising (a) nickel sulphide and/or cobalt sulphide, (b) molybdenum sulphide and/or tungsten sulphide and (c) fluorine. Substantially all the fluorine is incorporated by in situ fluoriding i.e. addition of fluorine compound (e.g. orthofluorotoluene and difluoromethane) to the gas and/or liquid stream passing over the catalyst. Nitrogen may be incorporated into the catalyst by addition to the stream of a nitrogen compound (many listed). A small amount of fluorine compound may be continuously added to the feed after the catalyst has reached its required fluorine content. The catalyst may comprise 0À025 to 0À5 g. atoms of Ni and/or Co and from 0À02 to 0À3 g. atoms of Mo and/or W per 100 g. carrier (e.g. SiO 2 , Al 2 O 3 , MgO, B 2 O 3 , Th 2 O 3 ). Crude benzene and petroleum distillates (final b.p.=375‹ C.) may be hydrogenated, the latter after hydrogenation being suitable for use as aromaticsfree solvents, illuminating oils, jet fuels and diesel fuels.

A bolt s with handle s<5> sliding beneath the seat at each side thereof is adapted to engage beneath the extensions r<1> for locking the seat to the sides. Disengagement of the bolt from the rear extension r<1> is permitted by providing a notch in the bolt at that part. The handle-bar l is detachably and reversibly connected to sleeves a<3> on the short axles a<1>. The handle-bar is jointed at l<3> so that handle may be adjusted in height to suit the person wheeling the vehicle, and is secured in position by thumb-screws l'. A support or prop m is mounted upon the pivots l<3> of the handlebar so that it may be swung out of the way; to hold it in the out-of-use position it may grip the lower parts of the handle-bar l. The back q is hinged to the seat o so that it may be turned into a substantially horizontal position.

Title: Improvements in or relating to machines for packing cigarettes

Filed: 1930-05-06
Abstract: 350,176. Packeting cigarettes. MOLINS, W. E., HORGAN, G., and MOLINS MACHINE CO., Ltd., 2, Evelyn Street, Deptford, London. May 6, 1930, No. 13877. [Class 94 (i).] Apparatus for arranging oval cigarettes in lapped formation comprises means for delivering a row of cigarettes to a table with their major axes parallel thereto, means for conveying the cigarettes through guides which rotate or tilt the cigarettes so that their major axes lie at an angle with the table, and means for moving the tilted cigarettes towards one another to obtain the lapped formation. The cigarettes are fed from a hopper through spaces between vertical vanes 2 to a table 3, on which they lie flat. A conveyer 4 with pusher pieces 5 moves them longitudinally into a series of grooves 9, the cigarettes being guided into the grooves by fingers 10 formed in a spring-pressed block 10a. They are then led between guides 7, the exit spacings of which are narrower than the major axes of the cigarettes, the tilting being effected by curved ribs 8, which engage one side of each cigarette and hold it downwardly. The guides 7 are carried in a frame pivoted at 12 so that they may. be lifted should a jam occur, the frame being also movable upwardly in slots to allow the passage beneath of the pusher pieces. The tilted cigarettes are then led to a tapering guide channel 13, 15, subdivided by guide members 14,. the lapped formation being thus obtained. To superimpose two or more layers, a cam-operated plate 20 receives each layer and presses it downwardly, the light spring 21 resting on the leading ends of the cigarettes, the superimposed layers being moved into the guide space 17 by pusher elements 18 carried by a conveyer 19. If it is required to pack the cigarettes with the printed inscriptions uppermost, a modified form of guide, Fig. 7, may be used which will turn the cigarette completely over, the guide member being raised and lowered by detecting apparatus, e.g. light-sensitive cells which control the guides through electromagnetic relays.

The rubber is reinforced adjacent the opening by thin laminated sheets 11. The Specification as open to inspection under Sect. 91 comprises also a number of other constructions. In one form, Fig. 2 (Cancelled), metal leaves 4, 4<1> which may be apertured, divide a mass of rubber arranged between and adhesively connected to metal plates 1, 2. In a modification in which the support is circular in plan view, the metal leaves are annular. Fig. 15 (Cancelled) shows a construction in which spaced rubber bars 29 are arranged between metal plates 1, 2 or, as shown in Fig. 16 (Cancelled), a rubber mass 31 having longitudinally-extending holes 30 may be arranged between the plates. Other constructions in which the resilient support comprises elastic material adhesively connected between inner and outer members and having laminations embedded therein to increase the stiffness in radial directions or being formed with arms extending radially or substantially radially between the members, now form the subject-matter of Specifications 492,433 and 494,811. This subject-matter does not appear in the Specification as accepted.
