Abstract: 570,106. Repairing fractured boiler plates. GOODACRE, F. L., and TURNER, L. E. June 15, 1943, No. 9586. [Class 123 (ii)] [Also in Groups XVII, XXIX and XXXIII] Punctured or cracked metal &c. surfaces accessible from one side only, such as surfaces of boilers &c. are repaired by cutting out the damaged portion to leave an approximately regular aperture larger inone dimension than in that at right angles thereto, and closing the aperture by inner and outer plates larger in area than the aperture, the inner plate being secured to a separable tool by which it is passed through the aperture and held whilst the outer plate is secured to the inner plate, the edges of the aperture being then clamped between the plates by means of bolts passed through the outer plate to engage non-rotatable nuts carried by the inner plate. A nut 14, outer plate 2, washer 15 and inner plate 3 with non-rotatable nuts 8 are threaded on to a tool 11 the end of which is then screwed into the bore of an internally and externally threaded mushroom headed bolt 10 with flats 102 adapted to engage the sides of a slot in the plate 3; the nuts 8 may be welded, &c. to the plate 3, or secured thereto by wires &c., or be movably held to allow centreing movement. The plate 3 is then passed through the aperture 1 in the surface under repair, and the nut 14 is engaged with the outer thread of the bolt 10; bolts are then passed through the plate 2 into engagement with the nuts 8, the bolts either passing through the aperture 1 or through holes surrounding the aperture. Washers of zinc. lead, leather, fibre, &c. may be provided between one or both the plates 2, 3, and the surface under repair.

Title: Dehydrogenation process
Inventor: DUCK EDWARD WILLIAM
IPC: C07C5/54
Filed: 1963-03-11
Abstract: The dehydrogenation of butenes, isopentenes or ethylbenzene is effected by heating to 200-900 DEG  C. in the presence of sulphur dioxide and ammonia. A catalyst such as SnO2, Fe2O3, V2O5, MoS3, K2MoS4 or WS3 may be present supported if desired on pumice, charcoal, silica or brick. The partial pressure of hydrocarbon is preferably 0.1-1 atmosphere and is reduced by the use of air or steam. Ammonia is added in an amount of 1-2.5 mols. per mol. of sulphur dioxide which is present in a mol. ratio to hydrocarbon of 0.1-2; oxygen as air is used in amounts up to twice the stoichiometric amount for dehydrogenation.  The ammonia and sulphur dioxide are preferably added in the form of ammonium sulphite, sulphate, bi-sulphite or bi-sulphate. Reaction times of 1-3 seconds are used, and ammonia and sulphur compounds are recovered and re-used. Specification 984,901 is referred to.

The frames are carried by chains 8 engaged with wheels 9 and 13, the latter operated by crank mechanism 10, 11 from an eccentric 12. The pieces of fabric 15, 16 have. goods - catching' arms 17 and openings 18 for the passage of the material. A recessed feed roller 23 driven from the shaft 14 of wheels 13 intermittently feeds material on to the top piece of fabric and in the reciprocation of the frames 4, 5, the material passes down over the pieces of fabric, and is finally discharged by a worm conveyer 27. Meanwhile, gas for roasting is passed upwards through the shaft.

To prevent snaking between a tractor and trailer angular movement about a vertical axis between members of the coupling is reduced by providing a lining or pads of friction material between said members, and the invention is characterized in that the lining or pads is or are of brake lining material. A part 16, Fig. 2, may be tightened down against brake lining friction material 17a in in a bracket 12, the ball 11 being fastened to the socket .13 by a removable pin 21 so that relative movement in a horizontal plane between the coupling parts may be confined to the frusto conical portions. In Fig. 3 the ball is not so pinned but the element 23 is provided at its top 30 with side flats which may be engaged by a forked member 27 hinged to an outwardly slidable bar 26 on the trailer, this arrangement ensuring that the ball rotates only about a horizontal axis and that the element 23 turns about a vertical axis against the lining 24. The part 23 may however be replaced by a plug of brake lining friction material bonded to the bolt 22. In a modification the socket 13 is horizontally hinged to the trailer draw gear and engages directly with a frusto conical spigot covered by brake lining friction material, the mating coupling elements being tightened together by a handwheel engaging a screw threaded bolt passing through the elements. In a further modification a ball socket may be provided with screw adjustable brake lining friction members.

Title: Process for making an improved gasoline
IPC: C10G63/04
Filed: 1941-08-28
Abstract: 551.663. Cracking hydrocarbons. INTERNATIONAL CATALYTIC OIL PROCESSES CORPORATION. Aug. 28, 1941, No. 9949. Convention date, Aug. 2. 1940. [Class 32] [Also in Group IV] Gasoline of improved octane number and stability is obtained by cracking a gas oil in presence of a catalyst which has already been used in the catalytic treatment of hydrocarbons, fractionating the cracked products to separate hydrogen, gaseous hydrocarbons and gasoline, and reforming the gasoline with or without the gases by passage over fresh or regenerated catalyst. The reforming operation effects the polymerization and alkylization of olefines, the isomerization of paraffins and the stabilization of unsaturates in the cracked product. Preferably the catalyst which has been used in the reforming is used without regeneration in the cracking stage. East Texas reduced crude vaporized in coil 3, heated to 825-850‹F. and separated from heavy fractions in flash evaporator 8, is formed into a suspension in an injector 12 with catalyst suspended in gases fed through line 128. The suspension is heated to cracking temperature in a coil or cylindrical reactor 28 and the cracked products pass to a cyclone separator 32 where catalyst is separated and falls down a baffled tower 33 to a hopper 39. The vapours pass through a cooler 46 to condense gas oil and thence to separator 50 where gas oil is removed through line 51 and optionally gases through line 55. The gasoline fraction is taken off through line 64 and formed into a suspension with regenerated catalyst supplied from hopper 63 to injector 57. The suspension is passed through line 68 to a coil or cylindrical reactor 70 heated to 650-850‹F. where the cracked vapours are reformed, the products passing to separator 74 where catalyst is separated and falls through a tower 75 to conveyer 80 and chamber 125 where it is again suspended in gas admitted through line 126 and fed through lines 128, to provide the catalyst for the cracking stage. The catalyst used in the cracking stage is fed from the hopper 39 to a chamber 103 where it is suspended is oxidizing gases admitted through line 104 and then fed through the coiled or cylindrical regeneration chamber 106 the regenerated catalyst being separated from gases in tower 59 and then fed through chamber 63 to injector 57 as catalyst for the reforming stage. Apparatus is described in which stationary catalyst is used in fixed beds in reactors instead of in suspension
