Patent GB-684130-A (GB)
Title: Improvements in and relating to the synthesis of hydrocarbons
IPC: C07C1/04
Filed: 1951-01-03
Abstract: Hydrocarbons rich in C2 to C4 olefins are obtained by passing CO and H2 at elevated temperature and pressure over an iron-base catalyst which is subjected to continuous or intermittent contact with chlorine, bromine or iodine, the corresponding hydrogen halides or a material releasing the same such as an organic halide.  Reaction conditions are generally 200-450 DEG , particularly 250-420 DEG  C.; 60-600 p.s.i.g.; 100 - 5000 vols./vol.cat./hr.; H2 : CO 1 : 2 to 5 : 1; recycle ratio up to 10 : 1.  Fixed or fluid bed reaction may be employed. In the former, initial activation of the catalyst with H2 and/or CO may be followed by treatment with carrier gas containing the halide or halogen, the temperature depending on the ease of decomposition.  Alternatively, the halide is added to the feed gas in gradually increasing concentration.  Continuous or intermittent addition during reaction is necessary, the amount in contact with the catalyst being sufficient to maintain hydrogen halide in the exit gas at least equal to that determined by the equilibrium, e.g. <FORM:0684130/IV (b)/1> The equations for calculating these amounts are given and, in an example, the amounts in grams/hr. are: Cl 0.04-4, Br 0.015-2.5, I 0.07-8.  Halogen compounds specified include butyl chlorides and iodide, ethylene dichloride and dibromide, dichlorbutane, trichlorpropane, dichlorethyl ether, glycerol dichlorhydrin, dichlorbenzenes, carbon tetrachloride, trimethylene chlorobromide, and ethyl iodide.  The iron catalyst may include promoters and supports.  Examples are given of fixed bed catalysts comprising iron oxide or ore, alone or with silica and in some cases copper, ethylene dichloride or dibromide, ethyl iodide, dichlorbutane, dichlorbenzene, trichlorpropane or hydrogen chloride being added by means of the synthesis or other carrier gas at various temperatures.  Fluidized catalysts are similarly treated with ethylene dichloride or chlorine.

When the latter is rotated, the shoes are radially displaced so that they bear on a cylindrical steel surface 65 to produce a braking effect. The spindle is mounted in ball-bearings 20, 27 and axial play is avoided by interposing a spring 23 between a ring nut 22 and a slidable but non-rotatable sleeve 25 which abuts the bearing 27. A felt washer 39 prevents grit from entering the bearings. The wheel 41 is preferably silicon carbide with a vitrified bond and has a surface speed between one and two thousand feet per minute. The base 10 may be shaped to suit a particular machine. An oiling plug 38 is provided.

Abstract: 812,591. Radio-active measuring. FOXBORO CO. Jan. 3, 1957 [Jan. 26, 1956], No. 344/57. Class 40 (3). A measuring system consists of radio-active source means emitting hard and soft radiation into two ionization chambers, the outputs from which are combined, the cham. bers being mounted together on one rigid support and the source means on another. Beta rays from a thallium 204 source 16 pass through an air gap 18 and the material under test 19 into an ionization chamber 12 which is faced by a stainless steel window 20. Chamber 12 is electrically polarized by electrodes 21 and 22, the current flowing through the chamber varying as a factor of the radiation. A second source 25 consists of hard radiation strontium 90. The outputs from the two chambers are combined differentially, amplified at 23 and displayed at 24. The two sources are fixed to a rigid support 32 which is adjustable by screws 35 and are provided with individual adjustment by screws 39. Pins 36 prevent rotation. The chambers are similarly adjustable. Alternatively only one source of radiation, caesium 137 which emits both gamma and beta rays, and two ionization chambers responding respectively to the beta and gamma rays may be used. The gamma-ray chamber may be pressurized.

Title: Improvements in a method of and apparatus for the calcination of gypsum
Inventor: SKINNER SIDNEY DAVID
IPC: C04B11/028
Filed: 1957-01-04
Abstract: 811,246. Drying gypsum. NATIONAL GYPSUM CO. Jan. 4, 1957, No. 448/57. Class 34(2). In a method of calcining finely ground gypsum, the gypsum is continuously fed lengthwise through a series of elongated heating zones, the heating being applied through the feeding means and also from a separate stationary supply. Powdered gypsum from a hopper 10 is fed by a screw conveyer 11 and conveyer element 24 to a chamber 18 where it is treated with a drying agent from spray nozzle 22 and passed through a screen 28. It is then passed segmentally through drying chambers 40...45 by screw conveyers 60...63 driven through flexible couplings 66. In each of the chambers 40...45 four inter-meshing screws 60-63 move the gypsum along until it overflows through a port 118 to shoot 114, 115 and thence to the next lower drying assembly. Drying is effected by passing heated fluid through ducts in the conveyer screws and through an external jacket 106 around each chamber. In order to increase and control the rate of flow of powder the bottom of each chamber 102 is provided with apertures 132 co-operating with a sliding gate 122 to allow the powder to fall directly from one chamber to the next. The calcined gypsum may be subsequently cooled by being passed through a similar equipment through which cooling fluid is circulated.

A sprocket 154 is rotatably mounted on the sleeve 120 and has teeth 156 engageable with teeth 158 on a sleeve 168 keyed to the sleeve 120 and which is axially movable to disengage the drive from the sprocket 154 to the sleeve 120, by means of an axially movable shaft 210 having a follower 232 engaged by a cam 228 rotated in 90 degree steps by pawl and ratchet mechanism operated by a lever 214.
Patent GB-822436-A (GB)
Title: Method of and apparatus for the continuous splitting of oils or fats
IPC: C11C1/04
Filed: 1958-01-07
Abstract: A method of splitting fatty oils in two or more autoclaves comprises passing the oil successively in countercurrent to the splitting medium, suitably steam, through the autoclaves, and is characterized in that in each autoclave having two tranquillizing chambers and a vapour chamber in common with the main reaction chamber, a separation of the reaction mixture into a solution of glycerol is effected in one tranquillizing chamber and into split or partially split oil in the other tranquillizing <PICT:0822436/III/1> chamber, and that, from the tranquillizing chambers, at least one separated component is fed with a free fall to the outside of the autoclave or into the next autoclave.  As shown, a suitable apparatus comprises autoclaves 1-4, each containing a tranquillizing chamber 9-12 for split oil and a further tranquillizing chamber 17-20 for glycerol water.  A pump 21-24 is also associated with each autoclave, and the vapour chambers 31-34 are maintained at a common pressure by means of line 35. Oil to be split passes along line 37, which contains a heat-exchanger 56 heated by fatty acid leaving the process, and then along line 38 to be sprayed into autoclave 1, together with a mixture of partially split oil and water which is removed from autoclave 1 by line 39, and glycerol water removed from autoclave 2 by line 40.  Steam is passed into the autoclave through lines 30, 29, as a result of which partially split oil rises up below the lower edge of partition 5 and separates from the water in chamber 9, which is not sprayed.  This oil falls through line 42 and is subsequently mixed with the mixture of partially split oil and water withdrawn from autoclave 2, before being introduced into autoclave 2 by means of pump 22 and line 46. The split oil therefore passes successively through autoclaves 1-4, while the glycerol water is progressively enriched as it passes in turn through autoclaves 4-1.  The fatty acid is eventually run off from autoclave 4 through sluice 93, and the glycerol water from autoclave 1 through sluice 57, the rates of run-off being controlled by valves 95, 92 operated by floats 94, 91.  A constant rate of throughput is obtained by means of throttles 97-100.  Two other embodiments, similar in principle, are also described, in one of which the contents of the autoclave are mechanically agitated.

The smalls delivered from surface 2 may be subjected to further sorting on surface 32 which has a baffle 34. All three surfaces 1, 2 32 are mounted on a variably inclined platform 22 and are oscillated by crankshaft 28 driven by motor 24 and all may have their inclination variable. The material may be sprayed with water and the surfaces heated.
