Title: Improved process and apparatus for the electrostatic separation of particles having different electrical susceptibility
IPC: B03C7/06
Filed: 1939-11-30
Abstract: 537,819. Electrostatic separators. SUTTON, H. M., and STEELE, B. R. Nov. 30, 1939, No. 31148. [Class 72] In the electrostatic separation of particles having different electrical susceptibilities, the particles while in contact with a separated electrode are subjected first to an electrical brush discharge and then to the inductive effect of an electrode containing an electrically conducting gas which does not produce ionisation of the surrounding air such as neon or helium, so as to modify the action of the brush discharge on some of the particles and effect the desired separation. The maternal is fed from a hopper C on to a rotating electrode B where it is subjected to a brush discharge produced by an electrode D comprising a row of sharp points pivoted on a rod 19 which is adjustably mounted in a sleeve C carried by a support 26. A curtain E of a suitable insulating material and provided with a metallic facing F is loosely mounted on a rod 30 adjustably connected by links 33 to the hopper C. The material then passes through an inductive field produced by an electrode D<SP>2</SP> containing an electrically conducting gas which does not produce an ionisation of the surrounding air such as helium or other rare gas and the separated material is collected in separate heaps by the interposition of adjustably mounted partitions I, I<SP>2</SP>. Any articles clinging to the electrode B are removed by the rotating roller O composed of felt washers packed closely together. The electrode D is adjustable so that it may be placed in any one of the positions D<SP>3</SP>, D<SP>5</SP>, D<SP>6</SP>. A reciprocating feed pan L actuated by a rod 25 from an eccentric M is located at the outlet end of the feed hopper C, and may be heated by an electric heater N. U.S.A. Specification 1,386,287 is referred to.

Title: A new or improved retaining device for members mounted for sliding movement
IPC: E05C17/22
Filed: 1931-11-10
Abstract: 383,411. Stays ; door stops and holders; stud-and-socket fastenings. WOODWARD, R. H., WOODWARD, B. A., 23, Legge Lane, Birmingham, and ANDERSON, J. R., 32, Riches Street, Wolverhampton. Nov. 10, 1931, No. 31188. [Classes 44 and 65 (i).] A retaining device for slidable or movable members which are provided with one or more holes, recesses or projections comprises a body in which is slidably mounted a hollow catch member having a pin or the like adapted for engagement with one of the said holes, recesses or projections, a spiral or conical spring being disposed between the catch member and the body to move the catch member into the engaging position ; a spiral or conical spring is used in order to allow the height of the device to be reduced to a minimum, since the coils of such a spring, when compressed, fit inside one another. Fig. 3 is a section through the device as applied to a casement stay comprising a bar 6 hinged at one end to the window and sliding through a retaining device mounted on the window frame. The body 8 of the retaining device is pivoted on a fixing plate 10 and has apertures 9 through which the stay bar passes, these apertures having curved upper edges to contact with the edges only of the stay bar to avoid scratching the surface thereof. In the body 8 is slidably mounted a member 12 which has a large aperture 13 for the stay bar and has a pin 15 fixed in its lower part to engage with recesses 14 in the stay bar; the member 12 is pressed upwardly by a conical spring 17 housed in the bottom of the body 8, and the stay is disengaged from the device by pressing down the member 12, against the spring, to bring the pin 15 clear of the stay bar. Fig. 4 shows a door holder of the stud-and-socket type, comprising a stud 21 fixed on the door and arranged to enter a retaining device 23, similar to that described above, fixed in the required position for holding the door. The sliding member 24 of the retaining device carries a screw 25, the end of which is shaped to engage a groove 22 in the stud 21 under the action of the conical spring 26 pressing on the member 24. The neck of the stud 21 carries a rubber buffer ring 32, adapted to contact with the body 23 of the holder.

Abstract: 456,788. Filing papers. NATIONAL BLANK BOOK CO., Holyoke, Massachusetts, U.S.A. Nov. 18, 1935, No. 31873. Convention date, Feb. 12. [Class 146 (i)] In a ring binder having toggle-connected ring plates and a cover plate, an operating- lever is pivotally connected to the ring plates and cover plate and is operable to move the ring plates to or from open or closed position, and one of the pivotal connections is sufficiently slidable to permit positioning of the lever with respect to its pivots so as to lock the ring plates in closed position. The lever 6 is pivoted about notches 18, Fig. 4, in an opening 11 in the spring cover-plate 1, Fig. 12, intermediate the rings 5, and may bear directly on the plate 1 or on a stiffening plate 12, provided with an opening the edge 16 of which overlaps the opening 11, and with a positioning nose 14 engaging a hole in the plate 1. The lower arm of the lever 6 is formed as an eye 7 in which is rotatably mounted a pin 8, notched at either end so as to engage recesses 10 in the hinge-line edges of the toggle-plates 3. With the longer arm of the lever 6 vertical the toggle-plates are in their upper position and the rings 5 are open ; after the toggle-plates have been depressed and the rings closed, the lever may be turned still further to the position shown, so that attempts to open the binder by forcing the rings only press the lever 6 against the plate 1. Alternatively the lever has its arms 23, 31, Fig. 18, set at such an angle to each other that the arm 33 lies at right angles to the plate 1 when the rings are locked, and is pivoted on an end-cap 27, fitting over the end of the plate 1. The cap 27 is held in position by a spring 28 engaging notches in its upper face, and which may be raised to release the cap by pressing a pin through a hole 29.

Abstract: 1,185,527. Electrolytic tin-plating of steel sheet. CENTRE DE RECHERCHES DU FER BLANC. July 12, 1967 [Aug.8, 1966], No. 31970/67. Heading C7B. In a method of electrolytically tin-plating sheet steel comprising subjecting sheet steel to alkaline degreasing, pickling in an acid bath, electrolytic preliminary coating, electrolytic tinning using an acid bath, and fusing and cooling the deposited tin, the preliminary metal coating is applied in the acid bath which is used for pickling, which acid bath contains bi-valent metal ions e.g. nickel and/or stannous ions, which can form a metallic electrodeposit in an acid bath when the concentration of bi-valent metal ions is low compared to the hydrogen ion concentration. The metal ions may be introduced into the acid pickling bath by use of a soluble anode, placed among unsoluble anodes, or by introduction of used or excess tinning bath. The pickling/electro-deposition step may be proceeded by a conventional pickling step. A pickling bath containing stannous ions preferably also contains an anti-oxidant such as an acid belonging to the phenosulphonic acid family, e.g. cresolsulphonic acid or phenolsulphonic acid, or a mixture of the latter with sulphuric acid; and non-soluble anodes which may be used in this step include graphite, stainless steel or iron silicon alloy.
