Title: Improvements in or relating to contacting subdivided solids with gaseous fluids
IPC: B01J8/18
Filed: 1942-10-30
Abstract: In processes for the catalytic conversion of hydrocarbons, e.g., cracking, dehydrogenation, polymerization, isomerization, of the kind in which a suspension of hydrocarbon vapours and catalyst is passed upwardly through a vertical reaction chamber of enlarged cross section as compared with the inlet and exit passages thereto, the chamber is provided with horizontally arranged baffles which prevent recirculation of the catalyst; a similar chamber is provided for regenerating the spent catalyst.  A suspension of vapours and catalyst is introduced through pipe 16 into a reaction chamber <PICT:0584252/III/1> <PICT:0584252/III/2> <PICT:0584252/III/3> 10 provided with perforated horizontal baffle plates 12.  The cracked vapours leave the chamber through pipe 18 and are separated from catalyst in a separator 42 passing thence through line 44 for further treatment, e.g., fractionation and recovery of gasoline.  The fouled catalyst falls through a pipe 48 and suspended in steam supplied through line 54 to mixer 52, is fed upwardly through a similar vessel 62 also provided with baffles 64.  Oxygenating gases are supplied through line 69 to burn off carbonaceous deposits and regenerate the catalyst.  The suspension is passed through a separator 74 where the catalyst is separated and fed to hopper 22 for return through line 32 to the reactor 10. Modified form of baffle plates are shown in Figs. 2 and 3.

Abstract: 1,139,132. Delivering measured quantities of liquid. PERKINS ENGINES Ltd. 7 April, 1966 [10 April, 1965], No. 15334/65. Heading B8N. [Also in Divisions F1 and F2] A metering unit 14 for a lubricating system (Division F2) comprises a housing having a bore 41 connected between a pulsator and bearings, and a branching bore 42. In operation a pulse of lubricant depresses piston 43 against the action of spring 46 and piston 44 against spring 45. As lubricant pressure falls piston 43 extends and lubricant is trapped in-bore 42 and then expelled by piston 44 through bore 41 to the bearings. A number of units are supplied in Figs. 7a-7c (not shown) the end of supply line (48) being closed or having a check valve. In Fig. 8 (not shown) concentric supply and return tubes (61, 62) leading to the metering unit (14) prevent an air lock.

Filed: 1970-04-01
Abstract: 1307537 Winding webs WINDMOLLER &  HOLSCHER 1 April 1970 [22 April 1969] 15397/70 Heading B8R A web 1 is wound into a coil 39 on a driven mandrel 12 mounted between two discs 10, 10<SP>1</SP> which are rotatable about a central shaft and which also support an empty mandrel 13 provided with an adhesive-coated cardboard sleeve 24. When the coil 39 has reached a predetermined diameter the discs 10, 101 are rotated 180 degrees to bring the empty mandrel 13 into the winding position (Fig. 2, not shown); a pneumatic cylinder 30 is actuated to swing a pressure roller 26 into contact with the web which is thus pressed on to the prepared sleeve 24, and then pneumatic cylinder 31 is actuated so that a knife 38 swings on arms 37, 37<SP>1</SP> to sever the web between the mandrel 12 and the wound coil 39 (Fig. 3, not shown). The knife 38 is then withdrawn, but as winding proceeds the roller 26 remains in contact with the coil, at first under pressure from the cylinder 31 and then, after a few convolutions have been wound, under the influence of gravity to ensure a compact winding free of air inclusions.

Title: Improvements in moulds for matrix setting and type-line-casting machines
IPC: D06F83/00
Filed: 1935-05-30
Abstract: 436,644. Type-bar-making machines; printing-surfaces. TYPOGRAPH GES., 17, Huttenstrasse, Berlin. May 30, 1935, No. 15797. Convention date, June 28, 1934. [Classes 100 (ii) and 100 (iii)] Moulds; trimming type-bars.-Relates to moulds of the kind having between the metal-pot mouthpiece and the mould a movable slotted intermediate plate, in which is formed a wastepiece which is shorn off after the casting, so as to give a finished slug. The adjacent faces of the mould 1, Figs. 1 and 7, and of the intermediate plate 7 are provided with interengaging teeth 8 over the whole of their surfaces, and the pouring-in slot 9 of the plate 7, which extends over the entire length of the mould, is divided into a series of conical holes 10, which taper towards the mould and are formed in the projecting teeth of the plate. The formation of eddies and bubbles in the molten metal, and the drawing back of the metal during the return of the pump piston, are thereby prevented, and the escape of air from the mould is facilitated. The foot of the slug has a uniform toothed formation 13, Fig. 13. Shortening of the slug by cutting is thereby facilitated, and the line can be cast of any desired length more conveniently than in the case of the known form of slug that has short feet at the ends, connected by a narrow foot strip extending along one side of the slug. The waste-piece is shorn off by upward movement of the intermediate plate 7, and the slug is ejected through a slot 17 in the plate. The mould is adjusted for length by means of liners 3, operated by racks and pinions. For short lines, one-half of the mould slot is filled by an insertion piece 20, Fig. 6, having holes 21, through which the distance-screw 5 of the mould can pass. The mould can be shortened to the width of a single type. The liners 3, 20 may each have one or more teeth 22 to engage with those of the intermediate plate, so as to hold them in position and permit of adjustment in steps equal to the width of a tooth. For finer adjustment, liners having parts 23, Fig. 6, which project to different extents beyond the teeth 22, may be employed.

The wheels 1 which rotate on the shaft 4 and which are connected by a sleeve 3 are each provided with internal teeth which engage a double pinion 21, 20 mounted in the frame 5 and driving through a pinion 22 a pinion on a sleeve 23 adapted to transmit uni-directional motion to the spindle 15. The gears are enclosed in a case 16. The ledger blade 27 which is pivoted on studs 31 projecting from the members 11 is fitted at each end with an upstanding arm 28 curved to pass round a boss 13 in which the cutter spindle fits and carrying a stop piece 30 adapted to be adjusted by set-screws 33. The mower roller is journaled on brackets 35 which can slide in guides 36 and which are adjusted in position by spindles 37 screwed through brackets 38 on the members 11 and provided with handles 39. An adjustable handle is pivoted or otherwise secured to the frame 5.
