Title: Improvements relating to the production of metal articles with holes in them
Inventor: KEEGAN BARCLAY
IPC: B21K3/04
Filed: 1956-09-12
Abstract: 806,479. Making turbine blades; destructible cones. WIGGIN & CO. Ltd., H. Aug. 22, 1957 [Sept. 12, 1956], No. 27907/56. Classes 83 (2) and 83 (4). An iron-containing filler is removed from a metal article by first acid etching the article for a short time using an aqueous acidic solution which attacks both the article and the filler and then leaching the filler in a solution which attacks the filler solely or preferentially. The invention is concerned in particular with the production of turbine blades having cooling passages by the extrusion of filled billets made from nickel-chromium or nickel-chromiumcobalt base alloys. The filler may be of mild steel, iron-manganese-titanium alloys or sintered composition of iron and magnesia. The short time etching is stated to remove the oxide layer which forms on the filler during working; it is performed by immersing the article in a solution of equal parts of hydrochloric acid and water at boiling point, or at room temperature when combined with an electrolytic treatment. The final leaching is effected by an aqueous solution containing 25 per cent nitric acid and 1 per cent hydrochloric acid. Specific examples are given. Specifications 763,115, [Group II], and 765,199 are referred to.

Title: Method and Apparatus for the Continuous Casting of Metal.
IPC: B22D11/08
Filed: 1968-06-12
Abstract: 1,195,152. Continuous casting machines. SCHLOEMANN A.G. 12 June, 1968 [14 June, 1967], No. 28037/68. Heading B3F. In a continuous casting process a starter bar is connected to the cast ingot by connecting elements such as I-section rails, around which molten metal has solidified. The starter bar head is released from the connecting elements by relative movement transverse to the longitudinal casting axis. Starter bars with integral or separable heads can be used. In the latter case, the starter bar head is preferably separated from the rest of the starter bar before disconnection of the starter bar head and connecting elements. The starter bar head is preferably removed before the "crop end" is cut from the ingot. The cast ingot 1 leaves guide rolls 2 to enter a device 3 which disconnects the starter bar head from the connecting elements by gripping the ingot between rolls 3<SP>11</SP>, while the starter bar head is moved upwards, after having moved into a cage 5 (raised by a winch 6, 7, 8). Alternatively, disconnection may be effected by an hydraulic ram 5<SP>1</SP>. With the starter bar in a raised position, new connecting elements are inserted into the starter bar head. A cutter 45 removes the "crop end" from the ingot. Fig. 3 is a plan of the top of a starter bar head, of which, the face 11 contacts molten metal. The face 11 is sheet metal backed with asbestos and is canted to avoid entrainment of the ingot with the starter bar. A shoe 13 has a recess shaped to engage a connecting element (scrap railway rail). Should the molten metal weld to the shoe, the shoe will break away from the starter bar head during its disconnection from the connecting element as the bolts 17 shear at a prescribed release pressure.

In a current collector in which a current collector member 8 supported on a pantograph framework is arranged to allow the collector 8 to move perpendicular to the supply wire, the current collector member 8 is pivotally supported on a carrier member 6 pivotally supported near the lower ends of transversely spaced link members 3 suspended from pivots 2 at the pantograph apex, first springs 7 maintain the link members 3 in alignment with the carrier member 6, second springs 10 act on the carrier member 6 below its pivotal supports to maintain it in a vertical position and tension springs 9a, 9b disposed forwardly and rearwardly of the carrier member 6 interconnect the collector 8 and link members 3 to maintain the collector member 8 perpendicular to the link members 3 and the arrangement is such that displacement of the collector member 8 in a rearward direction relative to the.pantograph apex displaces the lower ends of the link members 3 in a rearward direction to increase the tension in the forwardly disposed tension springs 9a and decrease the tension in the rearwardly disposed tension springs 9b. A thin metal collector 8 carrying contact strips 8b is mounted, by bearing members 8a engaging journals 6c, on a bow 6 having a central straight portion 6a and downwardly curved outer portions 6b. The bow 6 is supported by extensions 5 mounted on the ends 4a of a pin 4 carried by a U-shaped member 3 mounted by a pin 2 on the ends 1a, 1b of arms 1 forming part of a pantograph framework. The lower end 3a of the member 3 is connected by a spring 7 to the extensions 5. The collector 8 is attached by the members 8a to arms 3b on the member 3 by tension springs 9a and 9b. The extensions 5 are connected to the arms 1 by tension springs 10. When the vehicle is at rest. the assembly is held by the springs 10, 7, 9a and 9b in the position shown in Fig. 1 and when the vehicle is in motion the friction between the collector 8 and the conductor 11 deflects the assembly to the position shown in Fig. 4. In the deflected position the tension in the leading spring 9a is greater than in the trailing spring 9b and hence the leading part of the collector 8 is pulled downwardly away from the conductor 11.
