Title: Improvements in or relating to the hydrogenation of an aromatics-containing feed
Inventor: CHRISTMAN ROBERT DUDLEY
IPC: C10G45/40
Filed: 1970-11-27
Abstract: 1300599 Hydrogenating pyrolysis gasoline GULF RESEARCH & DEVELOPMENT CO 27 Nov 1970 [19 Dec 1969] 56619/70 Heading C5E In the hydrogenation of pyrolysis gasoline 12 using a noble-metal catalyst at a temperature sufficiently low that the hydrogenation is selective to diolefins over mono-olefins and aromatics, a hydrocarbon diluent whose boiling range is above that of the feed and which increases the proportion of the feed in the liquid phase at the process temperature is charged to the process. The effluent can be used as gasoline blending components or subjected to a second hydrogenation at 22, at a higher temperature to saturate the mono-olefins and produce a stream 30, from which benzene, toluene and xylene can be obtained, and from which a stream 32 of hydrogen and the diluent can be recycled to the first hydrogenation at 10. The first hydrogenation can be carried out at 24-204‹ C. and 56-70kg./sq. cm. gauge using a catalyst comprising Pd or Pt on alumina, e.g. with a chromium as a promoter. The second hydrogenation can be carried out at 149- 343‹ C. and a hydrogen partial pressure of 14-84kg./sq. cm. gauge using a catalyst comprising at lest one metal from Groups VI and VIII, e.g. Ni Co Mo, Co Mo or Ni Mo on alumina. Suitable diluents comprise hydrocarbons boiling within the furnace oil range, e.g. 149-454‹ C. and are used in amounts of 0À1-2 moles per mole of feed. Oil formed by the hydrogenation of dimers and trimers of the diolefins is included in the recycled furnace oil. The pyrolysis gasoline can be treated before the hydrogenation to remove styene and to provide a C 4  or C 5  to 177 or 204‹ C. naphtha for the hydrogenation.

Title: Device for Segregating Sheets in Cross-Cutting or like Machines
Inventor: BAUCKE HORST
IPC: B65H35/00
Filed: 1966-12-20
Abstract: 1,170,440. Delivering sheets. JAGENBERGWERKE A.G. 20 Dec., 1966 [13 Jan., 1966], No. 56943/66. Heading B8R. A cutting machine wherein sheets cut to different, lengths are moved in at least two different feed paths which are coplanar at a segregating station, includes a sheet segregating device comprising independently operable groups of sheet deflectors arranged for movement into and out of the feed paths to deflect faulty sheets therefrom there being means for varying the span of the operable groups of deflector members according to the width of the feed paths. In a cross-cutting machine paper web 2 is divided by longitudinal cutters 3 into webs 4, 5, 6 and 7 of different widths which are fed to cross-cutting sections 10 and 11 to give sheets of different lengths. Both sets of sheets are brought into the plane defined by feed belts 16 and 17 and then pass over deflector 18 either to the accepted stack 22, 23 or the rejected stack 26, 27. Device 18 consists of deflector fingers 28 rotatable on spindle 30 and each provided with a pair of rollers 31, 32 adapted to fit in recessed guides 35, 36 of driver members 33, 34. The driver members are connected to spindles 37, 38 turnable by levers 39 and 40 operated by cylinders 41 and 42. Provided a roller 31, 32 is engaged by a guide 35 36, actuation of cylinders 41 or 42 will displace a finger 28 into a position for deflecting a sheet to the rejected stack (Fig. 6, not shown). Spindles 37 and 38 are displaceable laterally in machine frames 47, 48 by means of hand wheel 51. Guides 35 and 36 are constructed as shown in Fig. 8 such that recessed regions 54, 56 in guides 35, lie opposite non-recessed regions 55, 57 in guides 36, 35 respectively. Recessed regions 54 become smaller and recessed regions 56 become larger from machine frame 47 to machine frame 48 by steps of one width of the rollers 31, 32 respectively. In Fig. 8 all deflector fingers 28 (a to i) are operated by guide 35 since all the rollers 31 (a to i) are located in recessed regions 56. Lateral displacement of spindles 37 and 38, hence guides 35 and 36 will bring one finger 28 under the control of guide 36 for each roller's width displacement. Thus fingers 28 can be assembled in various groups of different widths for deflecting sheets of different widths. The detection of faulty sheets is effected by electronic or optical devices, not shown, which check the web 2 before longitudinal cutting and are connected to actuating cylinders 41 and 42.

[Also in Group VI] An endoscope comprises a tube one end of which is insertable in a body cavity, the other end having means for viewing the cavity, an illuminating device remote from said one end and from which light is directed to said one end by multiple reflections in a transparent rod which is so disposed in the tube that space is left for the observation of the cavity or the passage of surgical instruments through the tube. The tube 1 provided with a bevelled end 2 contains a transparent rod 3 of quartz or " Plexiglas (Registered Trade Mark) for directing light to the field of observation. The rod 3 is preferably silver-plated except for a ground light emitting portion at the end and is enclosed in a sheath through which vapour at the end of tube 1 can be drawn. A casing 8 contains a lamp bulb 7 and reflector 12 and a condenser 9, 10 for focusing light on a reflecting prism 11 from which light enters the rod 3. A beam splitter consisting of two elements 20, 21 enables the observation held to be seen magnified through each of two eye-pieces 23, 25. Light passing to the eyepieces 23, 25 traverses apertures 15, 16 in a rotary shutter 17 which is electromagnetically operated through a foot control (not shown). A water-repellent glass slide 18 and a colour filter 19 or polarizing plate are placed between the shutter 17 and the eyepieces 23, 25. In order to prevent misting of lenses or glass plates, air between the shutter 17 and glass plate 18 is warmed electrically and withdrawn through a hose 28. An aperture 29 for the insertion of instruments or an auxiliary plane mirror is provided in the tube 1. Another form of endoscope which may be introduced into the tube 1 or used independently consists of a tube 30 containing an optical system A-B consisting of lenses arranged at intervals along its length. The front lens 32 is protected from condensed water vapour and mucous by a glass or silica plate 34 over which an air draught, which enters the apparatus at a nozzle 37 and passes down a pipe 35 within the tube 30, is provided. On leaving the optical system A-B light from the observation field passes through an eyepiece 38 and reaches a beam splitter which divides the beam so that the observation field may be seen through a pupil 43 at the same time as it is photographed by a camera 45.
