Title: Process for the production of sulphur
IPC: C01B17/04
Filed: 1954-05-25
Abstract: <PICT:0765354/III/1> In an apparatus, for the production of sulphur from a gas mixture containing hydrogen sulphide, having two chambers containing catalyst layers connected by an arrangement of valved conduits such that the gas mixture can be passed either through the two chambers in succession or through one of the chambers, the other through one of the chambers, the other being disconnected, the two valves, which direct the passage of the gas mixture through either or both chambers, each consist of a container enclosing a liquid sulphur-seal valve operated by adjustment of the level of liquid sulphur, and the containers are arranged outside the catalyst chambers.  Hydrogen sulphide-containing gas entering at 7 is burnt in combustion chamber 9 with a stoichiometric amount of air entering at 8.  The combustion products pass through 10 to sulphur container 11 divided into compartments 15, 16 by partition 13 and having deflectors 19.  Compartment 16 is filled with liquid sulphur so the combustion products pass through compartment 15, and thence by pipe 29 to auxiliary burner 30 and catalyst chamber 1.  From 1 the gases pass through separator 5, cooled by liquid sulphur drawn from sump 31 by pump 32 and pipe 34.  The sulphur outlets from container 11, chamber 1 and separator 5 pass by pipes 35 to sump 31.  The gases from separator 5 pass through pipe 36, compartment 18 of container 12, pipe 37, auxiliary burner 38, catalyst chamber 2, and separator 6, all of which are constructed and arranged in the same way as container 11, auxiliary burner 30, chamber 1, and separator 5, to stack 40. Containers 11, 12 are used as changeover devices to change the gas flow if necessary, instead of the usual slide valves which stick.  For example, if chamber 1 and separator 5 have to be put out of operation for catalyst renewal, compartments 16, 17 of containers 11, 12 are emptied and compartments 15, 18 are filled when gas flow is from pipe 10, through compartment 16, pipe 44, pipe 37 and chamber 2 to separator 6.  Alternatively, chamber 1 and separator 5 may remain in operation, while chamber 2 and separator 6 are cut out, by filling compartments 16, 18 and emptying compartments 15, 17 when the gases flow through chamber 1, separator 5, and pipe 36, to pipe 45. The containers may be divided into more than two compartments.  The liquid sulphur in the change-over containers may be maintained at 120-150 DEG C. by cooling or heating devices as required. Specification 752,354 is referred to.

Filed: 1955-06-06
Abstract: 796,880. Spring suspensions; adjusting body height. REGIE NATIONALE DES USINES RENAULT. June 6, 1955, No. 16196/55. Class 108(2) Relates to a compensating device for maintaining a substantially constant distance between a vehicle frame and a wheel assembly irrespective of load variations on the vehicle, the vehicle suspension comprising an elastic member supporting the vehicle chassis frame and resting on a first lever articulated to a second lever connected to the wheel axle. According to the invention, the device comprises a hydraulic installation arranged between a suspended member and a member connected to the wheel axle, the installation comprising a piston and cylinder assembly wherein the piston is moved by deflection of the suspended part of the vehicle and the cylinder is displaced in relation to the mean position of the piston and cylinder by a member sensitive to the mean height from the ground of the suspended part, the arrangement being such that upon a relatively considerable increase in load on the suspension the piston delivers liquid under pressure from a chamber on one side of the piston to a chamber on the other side of the piston whereby to extend the length of the piston and cylinder assembly and to reduce in length upon a reduction in load, by a lowering of the pressure of the liquid controlled by differential displacement of the suspended part and one of the members of the hydraulic installation to permit the suspended part to return to its normal position. As shown, levers 3, 5 supporting a suspension spring 2 and wheel axle 6 respectively are pivoted about a common axis 4 on the vehicle frame 1 and the inner ends 3<SP>1</SP> and 5<SP>1</SP> of the levers are pivotally connected to a cap portion 9 and to a cylinder 10 respectively of a hydraulic piston and cylinder device, the piston rod 11 of which is attached to the frame 1. Under normal load the parts are as shown in Figs. 1 and 2. Upon an increase in vehicle loading causing relative displacement between the cap 9 and cylinder 10, Fig. 4, liquid is forced by the piston through a valve 19 into a cylinder space 17 until pressure therein rises sufficiently to open the valve 23 to admt liquid to a space 21. As the pressure in space 21 increases the cap 9 is displaced outwardly to lift the frame 1, until the space 17 communicates through a duct 24 with an outer space 25. Upon subsequent decrease of load, communication between cylinder spaces 16 and 17 is restored, pressure in space 21 is relieved by a valve 27 on a piston rod 26 which permits flow between the space 21 and 17 and the cap resumes its original position. In another arrangement Fig. 7, (not shown) the piston and cylinder device is applied to a pneumatic spring suspension.

Title: Mixtures of glycidyl polyethers and butadiene copolymers
IPC: C09J109/00
Filed: 1953-06-12
Abstract: An adhesive composition contains 3-97 per cent by weight of a glycidyl polyether of a polyhydric phenol having a 1,2-epoxy equivalency greater than 1 and 97-3 per cent of an elastomeric copolymer of a major proportion of butadiene with a minor proportion of acrylonitrile, methacrylonitrile, styrene, methyl acrylate or methyl methacrylate.  The glycidyl polyether may be as described in Specification 681,099.  Specific examples are given of the preparation of five polyethers from epichlorhydrin and bisphenol. The elastomeric copolymer may be employed as a vulcanizate, e.g. a scrap being incorporated with the ether in finely divided condition. A filler such as carbon black and/or magnesium oxide or asbestos, alumina, silica or zinc oxide may also be incorporated.  The ingredients may be mixed cold or the ether if solid may first be melted, or the mixing may be effected on a roll mill which may be heated.  Solvents may be added, e.g. acetone, methyl ethyl ketone, methyl butyl ketone, cyclohexanone, isophorone, or mixtures thereof with hydrocarbons, e.g. benzene, toluene, xylene, ethylbenzene or cumene.  Vulcanizing ingredients for the copolymer, viscosity-reducing liquids, e.g. dibutyl phthalate, allyl glycidyl ether, phenyl glycidyl ether, acetonitrile, or epoxidized fatty oil, for the polyether, and dyes, pigments, other resins and softeners may be incorporated. Curing agents for the polyethers, e.g. amines, fatty acid salts of amines, polycarboxylic acids, certain inorganic acids or their partial esters or Fridel-Crafts catalysts or their complexes are also suitable additives which are exemplified.  Curing is preferably effected at raised temperature.  In examples, 1, 2 and 3 pieces of aluminium were stuck together with a mixture of a glycidyl ether of bisphenol, and a copolymer of 60 per cent butadiene-1,3 with 40 per cent acrylonitrile containing asbestos and N,N-diethyl-1,3-propanediamine as curing agent.  Epoxidized soybean oil may be added as a reaction diluent.  Examples 4, 5 are similar, but employ a vulcanized co-polymer in particulate condition.  Other examples are similar, employing copolymers of 75 per cent butadiene-1,3 with 25 per cent acrylonitrile, and using different vulcanizing ingredients, fillers and curing catalysts.  Physical properties of vulcanizates of the compositions and of coatings prepared from them on metal or glass sheets are quoted.
