Title: Improvements in or relating to the production of spirits, oils and the like from coal or similar materials
IPC: C12P21/00
Filed: 1932-05-17
Abstract: 398,601. Materials for making gas and other products. DIXON, T. R., Pampisford Lodge, Pampisford, Cambridgeshire. May 17, 1932, Nos. 14028 and 16102. [Class 55 (ii).] Carbonaceous materials such as pulverized coal are treated with a bacterial organic acid prior to fractional distillation for the obtention of spirits, oils, gases, and a smokeless coal dust residue. Acetic acid or an acid produced by bacteria of the genus lactici, may be used. In an example, a mixture of powdered coal and acid are allowed to stand for about seven davs at a temperature of 128-132‹ F. The acidity of the mixture is then reduced bv addition of alkali, the temperature falling to 80‹ F., and the mixture left for a further 21 days. The surface liquor is then decanted from the coal dust residue and is again fermented by the addition of yeast and molasses, before being finally fractionally distilled. A slight electric current through the liquor shortens the process. Tar, wood, peat, or vegetation may be similarly treated.

Title: Railway route control system
IPC: B61L19/06
Filed: 1960-04-22
Abstract: 907,471. Route setting. GENERAL RAILWAY SIGNAL CO. April 22, 1960 [May 18, 1959], No. 14219/60. Class 105. In a route-setting system of the entrance-exit type a first portion of the desired route is set up in response to the designation of the entrance and exit locations of the route and a subsequent portion of the route is automatically effected after the first portion has been traversed by a railway vehicle. The invention enables a switch-back movement of a vehicle or train in one direction over one or more points in their normal or reverse position and then in the reverse direction with the points in their opposite positions. In practicing the invention, actuation of an entrance button, say 9PB, establishes an initiation circuit to designate all the possible exits to which the train may be routed from the entrance location designated. On actuation of the exit button, e.g. 13PB, of the desired route, this entire route is reserved and once one of the signal locations has been designated as the exit for a route, none of the other signal locations can be designated as an exit. If the route designated does not involve any switch-back operations, i.e. point-to-point route, the entire route can be set and locked. If switch-back operations are involved, i.e. end-toend route, as with exit button 13PB, a first portion or segment to signal the location 15 of the route including points 10W involved in the switch-back is set up with the points 10W in the required reversed position and points 14W in normal position. The associated signal 9 is then cleared and the train traverses the first segment to signal 15 and by means of track circuit control associated with sections 14T, 15T, the second segment of the desired route from signal 15 to signal 13 is immediately and automatically established with the points 10W in the opposite or normal position or the points 14W in the reversed position. When signal 15 has cleared, the train reverses its direction to proceed over points 14W to signal 13. Each push-button is depressed for an end-to-end route and is spring-biased for restoration to its normal position, is rotated for a point-to-point route and is pulled to cancel a route previously initiated.

Title: Improvements in or relating to rotary web undersurface printing machines
IPC: B41F9/02
Filed: 1924-06-18
Abstract: 235,008. Barker, R. W., (American Bank Note Co.). June 18, 1924. Rotary intaglio machines. - A rotary web printing - machine, in which impressions are taken from engraved plates 11, 12, 13, spaced apart on a cylinder 10 by a distance sufficient to permit of movement of the wiping-cloth 14 and polishing-cloth 15 in the intervals between acting on successive, plates, is constructed so as to effect the feed of the web 29 by the pull on it when engaged under strong pressure between the printing- plates 11, 12, 13 and the cylindrical part of the D-impression cylinder 16, the arrangement being such that when the impression cylinder is opposite the blank spaces on the cylinder 10, a band brake 33 is automatically applied to the shaft of the roll 29 so as to stop the feed and thus cause, the successive impressions to be close together. The machine is especially applicable for printing stamps from paper which has been gummed and dried before printing, and the printed stamps are fed to a cutting-device from which the individual stamps pass to a web of paper 72 coated with a substance such as paraffin having no affinity for ink, the sheets being wound up with the web 22, so as to prevent offsetting from one sheet to another. The printed web 29 is fed to guillotine cutters 81, 86, by a blanket 64 passing over rollers 19, 71, 65, the web 29 being pressed against the blanket by a roller 23 mounted in adjustable arms 26. The roller 19 is driven by chain gearing from the impression cylinder and at a slightly greater speed than the web. Tripping - arrangements; counting - apparatus. - The impression cylinder 16, Figs. 1 and 5, is driven from the cylinder 10 by a clutch comprising a spring-pressed pivoted tooth 100 on a member fixed to the cylinder 16. and a recess 102 in a ring 61 fixed to a gear 18 geared to a plate cylinder gear 17. The gear 18 is free on the shaft of cylinder 16 and is normally clutched thereto by the engagement of tooth 100. To declutch the drive a pivoted member 107 is moved bv a crank-handle 112 and link 111 to cause a roller 109 to engage a roller 103 on an arm on the pivot of tooth 100, so as to disengage the tooth 100 from the recess 102. This takes place only when the flat part of cylinder 16 is opposite the printing-cylinder. The member 107 is connected by a link 113 to a lever 115 which is arranged to operate the catch 116 for holding the cutters out of action, and is also adapted to prevent a lever 59 from entering a recess in the ring 61. The lever 59 in the normal working of the machine enters this recess, and operates a counting-device 57. The counting-device is thus tripped when the impression cylinder is detached from its drive.

Title: Extraction of thorium from aqueous solution
Inventor: AUDSLEY ARNOLD
IPC: C01F15/00
Filed: 1957-05-10
Abstract: Thorium is extracted from an aqueous acidic solution containing also iron by contacting the solution with a solution of an amine or amine salt containing at least five carbon atoms per molecule in a water-immiscible solvent.  Amines referred to are aliphatic primary amines containing 8-25 carbon atoms, e.g. of formula R.C(CH3)2NH2, where R is branched and contains 15-19 carbon atoms and 2-amino-2 : 4 : 4-trimethyl-pentane.  The solvent may be a hydrocarbon such as kerosene.  In selecting suitable amines and solvents, it is important that the amine salt formed by reaction with the acid liquor should remain soluble in the solvent.  The process may be applied to a barren liquor obtained when a thorium-containing uranium ore is reacted with sulphuric acid and the solution passed through an anion exchanger to sequester uranium.  In a complete process, the liquor, normally having a pH greater than 1 but less than that which results in thorium precipitation is contacted with the amine or amine salt solution.  The phases are then separated and the organic phase distilled off or, usually, treated with an aqueous mineral acid, preferably nitric acid, whereby the thorium is extracted therefrom. The aqueous and organic phases are separated and thorium precipitated from the former as hydroxide by means of ammonia.  In the example, an amine solution was shaken with sulphuric acid before the extraction to convert the amine to the sulphate form.
