Title: Improved process and apparatus for the production of colloid mixtures comprising metals and non-alloyable additive materials
IPC: C22C1/02
Filed: 1934-01-24
Abstract: 432,278. Bearing materials. BOROFSKI, H., 85, B³ltenweg, Brunswick, Germany. Jan. 24, 1934, No. 2501. Convention date, Feb. 25, 1933. [Class 12 (i)] [See also Group V] A colloidal mixture of a metal with a non-alloyable additive substance, e.g. graphite, is made by wetting the additive substance before its addition to the molten metal with a liquid e.g. water, glycerine, or o i 1, which completely evaporates in the metal its place being taken by the latter. In a modification, a mixture of the metal, additive substance, and wetting liquid is heated until the liquid is melted and the liquid completely evaporated. The invention is suitable for the production of bearing metals or alloys having bases of copper, lead, zinc, tin or aluminium. In the manufacture of bronzes and like alloys a component of the alloy e.g. zinc or tin, may be added to the additive substance in the form of a fine powder before or after the wetting but prior to the addition of the wetted substance to the molten metal. In the apparatus shown in Fig. 2, a mixture of graphite, finely ground white metal and glycerine from a funnel 28 is passed into a cylinder 25 and forced by a piston 29 through a pipe 26 beneath the surface of molten metal in a heated melting pot 10 which may be provided with a stirrer not shown. A mixture of the base metal, graphite and glycerine may be fed into the cylinder 25 which may be heated sufficiently to melt the metal and drive off the glycerine. The molten metal may be forced directly into bush moulds or equivalent for producing finished metal parts. The Specification as open to inspection under Sect. 91 comprises also apparatus consisting of a vessel 10, Fig. 3 (Cancelled), containing a tube 30 in which is an Archimedian screw 31 for forcing additive material from a tank 33 beneath the surface of the molten metal. A force pump 34 is arranged to eject the molten mixture through a delivery pipe 35. This subject-matter does not appear in the Specification as accepted.

A top holding- bar E is carried on an arm J pivoted at 4. A counterweight H is pivotally connected with an extension C of the link A and with an arm K pivoted at 9 on the frame C, and the arm J is connected with the arm K by a link L. The pivots of the links DD<1> on the carrier B are in line vertically or approximately so, and similarly with the pivots of these links on the frame. The apparatus is actuated by power applied to turn the link D above the axis 4. The first part of the turning movement raises the carrier upwardly, and the platform A tilts so that the wagon rests against a side support 3 on the carrier. When the wagon is in contact with the top support E, further rotation of the link D turns the frame C about its pivot 4 and inverts the wagon. In the construction shown, the top holding-bar E is moved downwards by the rotation of the link K, and its normal raised position is high so as to provide headroom for the passage of trucks. In Figs. 1 and 2 (not shown), the bar E is carried on in overhung part of the frame C and moves only with the frame.

Title: Process for cracking hydrocarbons in the liquid state
IPC: C10G15/00
Filed: 1957-01-31
Abstract: In a modification of the process for cracking hydrocarbons in the liquid state claimed in the parent Specification to produce acetylene, the mixture of hydrocarbons to be cracked is maintained at relatively high temperatures, preferably at 15-40 DEG  C. below the mean boiling-point of the mixture which is used.  Particularly good yields are obtained if high-boiling hydrocarbon mixtures are used which have a lower boiling limit higher than 100 DEG  C. and preferably higher than 150 DEG  C. at a pressure of 100 mms. Preferably the hydrocarbon mixtures to be cracked are circulated through a purifying plant to separate out solid particles, and to facilitate the lifting of the moving auxiliary electrodes, in addition the cracking vessel, the cracking liquid and the electrodes may be kept vibrating.  In examples: (1) a 50 mm. deep layer of coke-gas benzine is cracked at temperatures between 100 DEG  and 129 DEG  C., and from 36-37 per cent of acetylene is produced in the resulting gas; (2) using a 10 mm. deep layer of hydrocarbon residue boiling at 195-210 DEG  C. at 40 mms. and working at a temperature of between 150 DEG  and 205 DEG  C. cracked gases containing approximately 40-42 per cent of acetylene are produced.

Title: Improvements in or relating to the refining of waxes
IPC: C10G73/42
Filed: 1949-02-08
Abstract: Waxes are refined by treating the molten wax with 5-25 per cent, by weight of the crude wax, of a solid adsorbent to form a dry pulverulent mixture, extracting this mixture with a solvent for the wax, and recovering the wax from the solution.  Waxes treated are animal, vegetable or mineral waxes or artificial waxes obtained from the distillation of petroleum or from the destructive distillation of paraffinaceous shales.  Adsorbents specified are fuller's earth, active carbon, silica gel and alumina gel.  Petroleum spirit and ether are mentioned as solvents.  In a modification of the process the wax after mixture with the adsorbent is extracted first with a solvent for the impurities and then with a solvent for the wax.  In an example, a crude petroleum wax (pipe wax) is heated to 115 DEG C and added to 15-20 per cent of its weight of Fuller's earth.  The mixture is stirred and then extracted with 1-4 times (on the weight of the wax) of petroleum spirit.  The wax solution is concentrated by evaporation and the wax crystallized out.  This refining process is repeated twice and the wax is finally treated with a mixture of fuller's earth and activated carbon and extracted as above.  The purification of raw beeswax is also described.  Specification 354,775 is referred to.
