Title: Centrifugal separators
IPC: B04B11/02
Filed: 1932-11-11
Abstract: 410,143. Centrifugal machines. O'DELL, A. E., 285, High Holborn, London.- (Rinuy, L. ; 49, Rue de Provence, Paris.) Nov. 11, 1932, Nos. 31971 and 34175. [Class 23.] A centrifuge for treating a liquid mixture is provided with a skimming device, the position of which is varied in accordance with the position of the fluid surface in the centrifuge. The discharge tube 1 for the lighter constituent has a skimming nozzle 5, Figs. 1, 3, to enter the free surface of the fluid in the centrifuge. A vane 6 is pivoted to a sleeve clamped to the nozzle, and to a link 7 connected to a crank shaft 9. A forked crank at the top of the shaft embraces the neck of a screw 12, and movement of the screw adjusts the position of the vane relatively to the nozzle to vary the extent to which the latter dips in the liquid. The apparatus is suspended from the pivot 2, and is balanced by the weight 3 ; oscillation is checked by the dash-pot 4. A screw may be provided to move the nozzle axially in the separator. In the modification shown in Fig. 6, the position of the skimming nozzle 20 is dependent upon the rate of discharge of the lighter constituent. The discharge pipe 21 is fixed and the nozzle 20 is free to slide in it under the force exerted by the weight of the tank 22 which receives the discharge from the pipe 21. The discharge escapes over the weir 23. If the flow increases the tank and nozzle rock on the pivot 24 to lessen the depth of immersion of the nozzle. In a modification, the position of the nozzle is controlled by a float in the tank. In a further modification, the tank rocks with the variation in weight of the discharged liquid, and closes contacts to complete the circuits of solenoids which actuate pawl and ratchet gear to move the discharging nozzle. The nozzle may be replaced by a weir 52, Fig. 9, constructed like an iris diaphragm, and its diameter is varied by automatic means of the type shown in Fig. 6.

Abstract: 483,854. Preventing formation of ice on aircraft surfaces. DUNLOP RUBBER CO., Ltd., and FIELD, E. F. Nov. 24, 1936, No. 32101. [Class 4] In means for protecting aircraft from ice formation which include a permeable covering through which ice-preventing liquid is diffused, a strip or strips of absorbent textile fabric is positioned beneath the covering and forms one or more channels extending across portions of the threads of the strip or strips which channels and the threads extending therefrom serve to conduct and distribute the liquid to the covering. As shown, a strip 1 of absorbent fabric, e.g. bleached duck, is folded at 2 and secured by strips of adhesive and stitches to form the channel. A part or parts of the channel are preferably coated with a narrow impermeable band or bands of rubber or rubber coated fabric 6 which may be subsequently vulcanized to the channel. The channel may be seated in a groove 9 in the leading edge of the wing and the free edges 3 of the fabric are secured to the leading edge. The leading edge of the wing may be protected by an unvulcanized rubberized fabric. Several supply channels may be provided in the leading edge ; alternatively a plurality of channels may be formed in a strip of fabric. The channels may be formed of overlapping edges of the fabric or by strips secured to the fabric which may be bias cut. The channel may be secured to the wing through the intermediary of a grooved-member which may be made from cork. A fabric strip may be stitched to this member. In a modification, a foundation layer 22, Fig. 13, is secured to the wing and an embossed vulcanized rubber sheet 15 serves to spread the liquid supplied through a folded strip or strips 1. The strip is covered by e.g. leather 17 the edges of which are turned in as at 19 and secured to the layer 22. The surface of the leather 17 is protected by a permeable covering 18 of a perforated rubber sheet vulcanized to an inextensible backing. Fairing elements 21 of leather may be provided.

Title: A process for the production of alkenes or alkene mixtures in a pure or substantially pure condition, or of derivatives thereof
Filed: 1935-11-23
Abstract: In the production of alkenes or their derivatives from hydrocarbon mixtures obtained by cracking, in the absence of added reducing gases, initial materials containing paraffin wax and aromatic hydrocarbons, said initial materials are, prior to cracking, refined by means of chemical agents such as sulphuric acid or selective solvents such as liquid SO2 or furfurol to remove at least the greater part of the aromatics.  Alkene derivatives include alkanes, alkanols, ethers, esters, and sulphonation products, but not lubricating oils obtained by polymerization.  The initial material may be dissolved in a suitable solvent prior to refining.  Materials specified are mineral oils or their distillates or residues, tar oils, brown coal paraffin oils, crude paraffin wax, and sweating oil. If aromatics are formed during the cracking they may be removed by a second refining step.  A paraffinous petroleum distillate is extracted thrice at 80 DEG  C. with furfurol.  The raffinate is cracked in the vapour phase at 560 DEG  C. with addition of steam, and the distillate fractionated.  The fraction of 100--160 DEG  C. is sulphated at 15 DEG  C. with 90 per cent H2SO4, the product diluted, and the aqueous layer heated to 100 DEG  C. Fractionation yields secondary alcohols C7 to C9.
