Patent GB-667093-A (GB)
Title: Improvements in and relating to the production of aldehydes
Filed: 1949-01-31
Abstract: Aldehydes are produced from mixtures of olefines, particularly aliphatic mono-olefines having 3 and 4 carbon atoms in the molecule, in which ethylene is also present by decreasing the ethylene in the mixture to not more than 5 per cent by volume and continuously reacting the resultant product with carbon monoxide and hydrogen at superatmospheric pressure and elevated temperature in the liquid phase in the presence of a catalyst consisting of a cobalt salt of an organic acid dissolved in the liquid.  Suitable reaction conditions are a ratio by volume of hydrogen: carbon monoxide of 3 : 1, a temperature in the range of 100-180 DEG  C., pressure of 200-300 atm. and a gas: liquid olefine volumetric ratio of from 1000 : 1 to 3000 : 1.  If desired an inert solvent for the reactants may be present. Suitable organic salts of cobalt are, for example, the naphthenate and acetate.  The salt is preferably introduced as a solution in the reactant or in an inert organic solvent for the reactants.  The ethylene is preferably removed from the reactants before introduction of the catalyst and may be removed, for example, by distillation.  In the example, di-isobutene is substantially freed from ethylene and is treated with hydrogen and carbon monoxide in the presence of cobalt naphthenate to give nonyl aldehyde.

Filed: 1976-01-23
Abstract: 1525042 Shoe bottom presses SIGMA SpA 23 Jan 1976 [29 Jan 1975] 02630/76 Heading A3B A device for pressing soles on shoes comprises cushioning rubber blocks 14, 23 for mating with the shoe sole and shoe waist and a block 26 for the heel, the blocks being vertically resiliently movable under thrusting forces exerted thereon by the shoe 40 against reaction forces provided by springs 11, (39), Figs. 2, 3 (not shown) respectively. A switch (not shown) is thrown to move the blocks 14, 23 upwardly by means of a piston 2 which presses the blocks 14, 23 the shoe 40 and a last 43 against stops 41, 42 and to actuate a cylinder 16 inside a base plate 1 to release a pawl 33 from a rachet bar 35. The pawl 33 spring biassed at 34, is pivoted on a guide support (32) Fig. 3 (not shown) on the base plate 1 on which support slides a slide 29 on which bears a cup 25 supporting the heel block 26 and a heel bearing plate 27. The slide 29 carries the rachet bar 35. Motion of the end 37 of one piston rod 38 in the cylinder 16 from a notch 36 in the pawl 33 releases this pawl. The blocks 14, 23 and the heel supporting slide 29 are held up by tensioned springs 11, (39) respectively, springs 11 being anchored between a rod 12 on a frame 3 on the base plate 1 and a pin 13 connecting the lower parts of U-shaped steel blocks 8 in the frame 3 which blocks 8 support the rubber blocks 14, 23. Spring (39) is anchored to the guide support 32. Blocks 8 can move downwardly to contact the base plate 1, guided by the sides of the frame 3. When the shoe contacts the stops 41, 42 the blocks 14, 23 are pushed downwards until the block 23 contacts a switch 24 which vents the cylinder 16 and the block 23 contacts the frame 3. By means of a piston rod 17, oppositely disposed to the rod 38, a cross piece 18 and chains 19  connected via sprocket wheels 20 to rods 21, pawls 5 pivoted on shafts 4 on the frame 3 are released to engage corresponding rachet bars 9 on the blocks 8 under the bias of springs 6. The downward force of the blocks 8 is transmitted to bearing ribs 44 on the base plate 1 to lock the blocks in position. Further lifting by the piston 2 squashes the rubber blocks 14, 23, 26. During and after the pressing operation, air is fed to the cylinder 16 to disengage the pawls 5. Alternatively the pawls may be disengaged under the force of the springs 6. Polished steel sheets on blocks 8 separate the blocks 14 from each other. A leather sheet 15 rests above the blocks 14, 23. A screw 30 in the slide 29 adjusts the inclination of the heel cup 25. The pawl actuating device 16 can be pneumatic, hydraulic, mechanical or electromechanical.

Title: Improvements in and relating to the production of sulphur and sulphur dioxide
Inventor: FRANKLIN REGINALD GEORGE
IPC: C01B17/50
Filed: 1952-02-01
Abstract: A mixture of sulphur and sulphur dioxide is produced by indirectly heating a mixture of calcium sulphate, siliceous and/or argillaceous material and coal or charcoal to 900-1400 DEG C. in a vertical retort, at least 0.6 mole of carbon per mole of calcium sulphate being present in the mixture.  The preferred temperature range is 1000-1300 DEG C.  The calcium sulphate may be in any desired form, for example gypsum, but substantially anhydrous calcium sulphate, for example natural anhydrite or calcined gypsum, is preferred.  The coal may for example be anthracite or bituminous coal.  About 1 mole of carbon per mole of calcium sulphate is generally employed but up to 1.5 moles or more of carbon per mole of calcium sulphate may be present.  The siliceous and/or argillaceous material is desirably in finely divided form, one may be for example sand, loam, or clay.  The nature and quantity may be varied within wide limits.  For example it may be almost wholly silica, two moles of silica being present per mole of calcium sulphate; or argillaceous material, two moles of silica and alumina combined being present per mole of calcium sulphate. However clay is conveniently used in such quantity that the sum of the moles of silica and alumina is about 0.5 per mole of calcium sulphate, with a ratio of silica to alumina of substantially 2 to 1 by weight.  The mixture is desirably of a particle size of less than 300m  and preferably less than 150m . It is preferably granulated, with the aid of a liquid bonding agent if necessary, to form pieces of suitable size, for example 1/8 to 1/4 -inch granules. The granules are preferably dried before use.  It is generally desirable to cool the solid residue leaving the bottom of the vertical retort, for example by passing steam into the retort preferably at or near the bottom thereof.  The steam may be generated, at least in part, by injecting water at a point near the bottom of the retort.  It is desirable to prevent as far as possible the presence of oxygen. Specification 694,035 is referred to.
