Title: A method for the desulphurisation of crude benzene, petroleum oils, shale oils and of other hydrocarbon oils containing sulphur
IPC: C10G45/02
Filed: 1934-04-12
Abstract: Sulphur compounds are removed from petroleum and other oils by passing the oil vapours at normal pressure together with hydrogen or hydrogen-containing gas over a catalyst consisting of nickel deposited on aluminium hydroxide, or other metals of the 8th group of the periodic system, especially platinum or palladium, deposited in a finely dispersed state on carbon and heating to a temperature not exceeding 350 DEG  C.  The treatment of amyl sulphide in this manner yields isopentane, and dibenzyl sulphide yields toluene (mainly) with some dibenzyl.ALSO:Hydrocarbons such as petroleum, shale oil, or crude benzol are freed from sulphur compounds by passing the oil vapours at normal pressure together with hydrogen or hydrogen-containing gas over a catalyst consisting of nickel deposited on aluminium hydroxide, or other metals of the 8th group of the Periodic system deposited in a finely dispersed state on carbon, and heating to a temperature not exceeding 350 DEG  C.  Platinum or palladium deposited on active charcoal may be used.  Sulphides, thiophene and thiophane are thereby eliminated with the formation of hydrogen sulphide.  The catalyst may be regenerated after use by heating in a current of air.  The treatment of amyl sulphide in this manner yields isopentane, and dibenzyl sulphide yields toluene (mainly) with some dibenzyl.

Title: Improvements in drinking straws and methods of manufacturing such straws
IPC: B31F1/00
Filed: 1961-03-28
Abstract: 922,663. Drinking-straws. SAFE-T PACIFIC BAKING CO. March 28, 1961 [April 11, 1960], No. 11384/61. Class 14 (2). Drinking-straws are reinforced by curling or deforming inwardly one or both of their end portions so that concentric inner layers are formed which are preferably integral with the remaining portions of the straw. The straw may be made of paper, cellophane, or plastic, either spirally wound and glued, or extruded; before and/or after deformation it may be coated with a solidifying protective material, e.g. paraffin wax, polyethylene, polyacrylate, which should preferably completely fill the space between the inner deformed end part and remaining portions in the finished straw (Fig. 11b). The centre part of the straw may be provided with transverse corrugations to render it flexible. As shown (Figs. 1 and 4), straws 10 are fed from a hopper 12 into semicircular recesses 16 in a rotating drum 14, and are held in position by guides 22 whilst being moved downwardly to engage an endless belt 28 moving at a high speed relative to the drum 14 and at an angle to the direction of rotation thereof. By this means the straws, one after the other, are caused to spin in their recesses 16 and forced along them to engage the heads 37 and shafts 36 respectively (Fig. 4) of members 34 which turn in the straw ends, the shafts 36 being secured in grooves 38 in an end plate 35, by screws 39. Alternative and deforming means are described which utilize either a bent wire having two shafts and a U- shaped projection extending into the straw and recess, or a solid end plate at the end of the recesses which are then provided with projections to initiate the inward turning of the tube ends. By providing a second endless belt similar to 28 and setting each belt at an angle to the horizontal and to the other and by further providing deforming means at the other side of the machine, both ends of each tube may be reinforced.

Abstract: 696,393. Variable micro-wave electric attenuators. GENERAL ELECTRIC CO., Ltd., and DOMVILLE, A. R. May 16, 1952 [May 16, 1951], No. 11504/51. Class 40 (viii). A variable attenuator for micro-waves travelling through a section of wave-guide containing solid dielectric, comprises a rotatable rod of the same dielectric lying longitudinally in the waveguide and holding a substantially planar layer, of resistive material, the axis of rotation of the rod lying in, or parallel to, the plane of the resistive layer. As shown, two lengths of waveguide 1 and 2 (Fig. 2), of brass of rectangular cross section, are filled with solid dielectric material 3, which may be either polythene or polystyrene. Brass blocks 4 and 5, soldered to guides 1 and 2 are held together by bolts (not shown) passing through the holes 6. Co-linear, cylindrical holes 7 are provided in the dielectric material 3 in each of the guides 1 and 2, and are filled by a single rod 8 of the dielectric. Rod 8 is split along its length, and a sheet of cardboard 9 having fine grain carbon on one side, is sandwiched between the two halves of the rod 8 to extend diametrically across that rod over its cylindrical part; adjacent their ends, the rod 8 and the material 9 are tapered to reduce the impedance discontinuity there. A disc 11, formed integrally with rod 8, lies between blocks 4 and 5, and projects slightly beyond two sides 12, Fig. 3 (not shown), of the blocks, so that the disc can be turned by hand, to rotate rod 8, and with it the resistive material 9 to vary the attenuation. Disc 11 may carry a scale round its periphery marked, for example in decibels. In an alternative construction the attenuator is formed in an elbow-shaped wave-guide and the rod, which lies in one arm of the elbow, is rotated by an extension thereof passing through a hole in the wall of the angle of the elbow.
