Title: Improved process of and apparatus for removing the burrs and sharp edges of metal articles
IPC: B23D79/00
Filed: 1936-10-10
Abstract: 483,057. Removing burrs from strips and other metal articles. CAMION, A. Oct. 10, 1936, No. 27545. [Classes 83 (ii), 83 (iii), and 83 (iv)] In a process for rendering harmless the burrs or sharp edges of metal articles formed in producing the articles, the burrs or sharp edges are replaced by toothed, milled or other portions or edges having small projections or protrusions thereon. The articles may be supported and a die used for the process of removing the burrs, or the article when in the form of a strip 1, Figs. 3 and 4, may be passed between supporting rolls 3, 16 relatively adjustable towards and away from one another, and the sharp edges acted upon by bevelled rollers 8. These rollers may have plain operating faces in which case the article is passed through a, similar device in which the rolls 8 have milled or other faces 15 to produce the small projections or protrusions above referred to. A number of devices may be arranged to operate on a work piece in series. The work may be driven through the device by arranging for the guiding rolls to be driven or in some cases the work may be pulled through the device by hand. The work and milled &c. tools may travel at different linear speeds so that the projections formed on the edges of the work may be partially levelled. Instead of devices arranged in series a pair of oblique members 8, Fig. 7, may be combined to act simultaneously on all the edges of a. strip such as a band iron.

The peripheral fingers b are so constructed that when the central bulged portion d is in the release position they lie on a conical surface. The container may be formed with an internal ledge or shoulder under which the flanged or flared ends of the fingers engage. A horizontal bead or lip 2 or a vertical bead or both may be formed at the base of the fingers. The lip 2 may cover the rim of the container or engage in a channel 3 therein. An outer co-operating cap may be provided engaging a cam-track on the outer wall of the container by relative rotation of which the disc is moved from the release to the secure position.

Abstract: 355,978. R÷ntgen-ray tubes. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Kearsley, W. K. ; 1606, Randolph Road, Schenectady, New York, U.S.A.) Sept. 19, 1930, No. 28091. Convention date, Sept. 19, 1929. [Class 39 (i).] The area of the focal spot in R÷ntgen-ray tubes is automatically increased with increase of the space current in the tube, by a coil 54 external to the tube magnetically focusing the space current. The coil may be supplied wich current from the mains by a transformer 55. As the space current is increased by varying a rheostat 24 in the filament heating circuit, the current through the coil 54 is decreased by a transformer 58 the secondary of which is in opposition to the secondary of the transformer 55 and the primary of which carries the space current. The Specification as open to inspection under Sect. 91 (3) (a) comprises also tubes in which the area of the focal spot is controlled by an electrostatic focussing device 11, Fig. 3 (Cancelled), surrounding the cathode and supported by a glass tube 14. As the space current supplied through a mechanical, thermionic or electrolytic rectifier 21, Fig. 1 (Cancelled), increases, the negative bias of the device 11 relatively to the cathode 6 is decreased by a vacuum tube 27 carrying the space current of the R÷ntgen-ray tube 1 and connected between the device 11 and the cathode 6 of the tube 1. As the current through the filament 6 is increased, the current through the filament 30 of the tube 27 increases and the voltage across the tube 27 decreases. In a modification, the tube 27 is replaced by a double rheostat with one-half in the circuit of the filament 6 so that as the current in the filament 6 is increased, the voltage across the double rheostat, and so the bias on the device 11, is decreased. In another modification, Fig. 2 (Cancelled), using a self-rectifying R÷ntgen-ray tube, the tube 27 is replaced by a transformer 35 supplied from the mains 22. An adjustable winding 40 carries the space current and a winding 38 is connected between the device 11 and the cathode 6, in parallel to a high resistance 39 smoothing out voltage fluctuations. This subject-matter does not appear in the Specification as accepted.

Patent GB-283702-A (GB)
Abstract: 283,702. British Celanese, Ltd., Dreyfus, H., and Haney, C. I. Nov. 30, 1926. Acetic, propionic, and other lower aliphatic acids are extracted from aqueous solutions bv means of a mixture of a solvent for the acid and a hydrocarbon both of which are of lower boiling-point than the acid. The solvent may be ether, chloroform acetone oils, &c., and the hydrocarbon may be benzene, petroleum ether, or gasoline. The extraction may be effected in any well-known manner, for instance the solvent mixture may be mixed with the aqueous acid, the mixture being then allowed to separate into layers, or the treatment may be effected in a column, which may contain packing material, the extraction being effected in a counter-current. If the extracting agent is lighter, it will be introduced at the bottom and the acid at the top, and in the opposite case vice versa. Either or both liquids may be introduced by sprayers, nozzles, or the like, and the extraction product may be led direct to a still, being heated on its way if desired by the vapours of the solvent from the still. The solvent may be introduced as vapour into the acid in liquid form, and in that case it is preferred to have the two ingredients of the solvent of nearly the same boiling-point so as to enable a mixed vapour in any proportions to be obtained. Alternatively the two ingredients of the solvent mixture may be vaporized separately and introduced into the conduit leading to the extraction apparatus. The extraction may be affected in a column, which may be provided with packing and with a beating jacket. In an example the extraction is effected in a long column with a mixture of ether and petroleum ether which is introduced at the bottom through a finely-perforated nozzle. The acetic acid solution is introduced at the top through a valved inlet, and the exhausted liquor is withdrawn at the bottom through a valved outlet. The upper part of the column is provided with a sight-glass, and acts as a separating vessel, having a constantlevel overflow for the solution of strong acid in the solvent. The extraction is effected at ordinary temperature, the column being initially filled with acetic acid solution. Specification 20125/07 is referred to.
