Title: Improvements in methods of supplying substances to a bath of molten metal
IPC: C21C7/06
Filed: 1952-11-26
Abstract: In a method of supplying to a metal bath one or more substances required for desulphurizing, deoxidizing, dephosphorizing, addition of silicon or carbon, or for alloying or like purposes, when the substances are difficult to add owing to low density, high volatility or reactivity, the substances are ground or otherwise formed to suitable size and shape and then formed into briquettes each of which has an aperture therethrough and has end surfaces enabling a tight fit of one briquette on an adjacent briquette.  The briquettes are threaded on a rod or wire and pressed together, the unit so formed being immersed in the metal bath.  The topmost briquette or briquettes are formed of refractory material also threaded on the rod or wire to afford protection of that part from the surface of the molten metal including any slag thereon.  Preferably the particle size of the material is such that the briquettes have sufficient porosity to permit escape of gases formed on addition to the bath. Further the briquettes may be provided with a wrapping, e.g. of sheet metal or impregnated paper.

Abstract: 887,108. Waveguide pistons. TESLA NARODNI PODNIK. Sept. 19, 1958, No. 30038/58. Class 40(8). Coarse adjustment of piston 9 within waveguide 1 is provided by a longitudinallymovable member 21 associated with a locking device, and fine adjustment is provided by rotation of knob 27. Member 21 is in the form of a hollow tube and is attached to the knob 27 by means of a ring 26 whereby the two members move longitudinally in unison but are relatively rotatable. The member 21 is shown at its extreme left-hand position. The knob 27 is threaded upon a sleeve 33 which carries a number of resilient tongues 32 projecting radially through slots in the tubular member 21. Release of a plunger 25 allows a spring-actuated cone 23 to force the tongues 32 against the side of the waveguide 1 or against a tube 20 fixed within the waveguide, thereby locking the sleeve 33 against longitudinal movement. Rotation of the knob 27 is now effective to move the tubular member 21 longitudinally. The waveguide I may be of rectangular cross-section and the tube 20 of circular cross-section. The waveguide supports a holder 2, 3 for a crystal diode.

Title: Improvements in containers such as silos and the like
IPC: B28B23/00
Filed: 1933-10-31
Abstract: 427,802. Moulding segmental blocks and slabs. NOFRANGO, Ltd., 16, Molesworth Street, Dublin. Oct. 31, 1933, No. 30197. Convention date, Nov. 1, 1932. [Class 87 (ii)] [See also Group X] A method of moulding or casting segmental wall slabs for circular enclosures or containers, such as silos, consists in coating a frame of the desired curvature with a layer of concrete or the like, stretching a piece of hessian over this layer and securing its edges, moistening the hessian, and covering it when shrunk with an outer coating of concrete or the like. The moistening of the hessian may be effected by its contact with the wet surface of the concrete, or by the application of water or of concrete made specially wet for the purpose. In one construction, the frame comprises wooden side pieces 1, Figs. 1 and 2, transverse supports 2, having curved upper edges 3, a curved metal plate 4, and two end members 6. Screws 5 secure the plate 4 and side pieces 1 to the supports 2, and the end members 6 are nailed or screwed to the side pieces. The upper edges of the members 6 extend above the plate 4 and, with the side pieces, form the walls of a shallow receptacle, of which the plate forms the curved base. Concrete, cement, or plaster is poured into this receptacle and the upper surface thereof is smoothed so that it follows the curvature of the plate 4. Hessian 8 is then stretched taut over the smoothed surface and is secured to the side and end members 1, 6 by laths 7. After shrinking, the hessian is covered by an upper thin layer of concrete or the like. A slightly modified form of frame is also described. The segments may be coated with bitumen. In application, the segments are assembled with their straight edges in abutment, and are secured in position by binding wires, circular rods or straps 15, Fig. 6, which are tightened to ensure a good joint between adjacent segments. The wall thus formed is supported by an annular base comprising a number of concrete arc shaped slabs 13 having a grooved upper surface to receive the segments. A roof of canvas, wood, metal or concrete may be provided, and the floor may be of sand, gravel, broken bricks, wood, metal, concrete or of the kind described in Specification 376,259, [Group X]. The Specification as open to inspection under Sect. 91 comprises also a silo construction of increased height. For this purpose a flanged recess or seat is formed in the upper curved edge of each segment, thus providing an annular seating for the plain lower edges of a further series of segments which form an upper continuation of the wall. This subject-matter does not appear in the Specification as accepted.
