Title: Inclined hoist for blast furnaces for charging by means of hopper buckets
IPC: C21B7/18
Filed: 1920-08-17
Abstract: 165,355. Marks, E. C. R., (Pohlig Akt.-Ges. J.). Aug. 17, 1920. Charging.-In an inclined hoist for charging blast furnaces, the bucket crab consists of a frame with wheels and carries a drum 8 mounted to rotate, rise, and fall in guide-slots 9, and having two smaller lateral portions. The lower hauling-rope 3 is fastened to the larger drum at 10, and the upper rope 4 is fastened at 11, partly encircling the drum. The counterweight rope 14 is fastened at 13, and the bucket rope 18 is fastened to the smaller part of the drum at 19, encircling it in a clockwise direction. On working the winch 7 to which the hauling-ropes pass, the crab mounts the incline without rotation of the drum, until the upper stops are reached, when the drum rotates in a clockwise direction, unwinding the bucket rope. For setting down and picking up buckets the drum axle has rollers 21 which bear on suitable rails 22 at the lower end of the hoist, and raise the drum in the guide slots. In an alternative arrangement, the rope grooves on the winch 7 may be led spirally to a smaller part of the winch drum, so that at the lowest position of the crab the rope 4 unwinds from the smaller part, when a differential tension between the ropes 4, 3 rotates the crab drum and unwinds the bucket rope.

Title: A method and apparatus for butt welding a pair of tubular members
IPC: B23K13/06
Filed: 1956-08-03
Abstract: 815,620. Welding by pressure. COMBUSTION ENGINEERING Inc. Aug. 3, 1956 [Sept. 26, 1955 (2)], No. 23976/56. Class 83 (4). In a method of butt-welding two tubes coaxially, the closely spaced ends are heated to welding temperature and welded by axial pressure in vacuo, while enclosed within a small annular chamber. Apparatus for butt-welding tubes 10 and 12 without the presence of oxygen comprises annular members 22 and 24 of heatresistant material, such as asbestos glued to paper, cemented to the walls of the tubes at 16, 26 and 28 to form an air-tight chamber 30. Annuli 14 with radial flanges 20 are cemented together to form the annulus 22, the flanges projecting slightly beyond the ends of their respective tubes 10 and 12. The chamber 30 is connected to an exhausted container 32 many times its size so that on opening a valve 40 the chamber 30 is rapidly evacuated and collapses towards the tubes. Heat is then supplied by the induction coil 58 or other means and the tubes welded by axial pressure. In a modification the chamber 30 is formed by rigid annuli 42, 52 of a heat-resistant material, e.g. a ceramic and the seal is effected by inflatable toroidal tubes 44 and 54. In a further modification the member 42 may be a solid cylinder.

Abstract: 187,209. Aktiebolaget Vaporackumulator. Oct. 12, 1921, [Convention date]. Addition to 129,272. Steam regenerative accumulators.-In a plant comprising a motor T receiving steam from a boiler p through a valve Oit and exhausting into a pipe line L2 containing a steam regenerative accumulator A, the motor is the only consumer receiving steam directly from the boiler. The pipe line L<2> supplies steam to a paper mill M or the like through a reducing valve Ra2. Steam may pass from the boiler steam pipe into the pipe line L2 through an over-flow valve Oia which starts to open only when the valve Oit is fully open. A reducing valve Ria in a pipe connecting the boiler steam pipe and the pipe line L2 opens when the pressure in the pipe line drops to its lowest value.

Title: Method and apparatus for transferring commands from the control  site to the recording site in closed loop television installations

Filed: 1971-04-19
Abstract: 1317851 Selective signalling INDUSTRIE A ZANUSSI SpA 19 April 1971 [21 March 1970] 24714/71 Heading G4H A command is transferred from the control site to the recording (camera) site in a closed loop TV installation by selecting from the video signal sent from the recording site to the control site a predetermined number of line synchronizing pulses, and lowering the level of these pulses, the lowered-level pulses being counted at the recording site, the count being converted into a signal whose magnitude and destination are a function of the count. The latter signal may control camera vertical or horizontal shift, or focal length, stop or dollying-in of the objective. The video cable potential is lowered at the control site for a period during which the line synchronization pulses are counted at the control site, the period (and counting) being ended when the count equals the identity of an actuated one of a plurality of push-buttons (using a diode decoder). At the recording site, the line synchronizing pulses occurring during the period of lowered potential are counted and decoded to control the camera. Further pluralities of push buttons may be used in turn in conjunction with respective decoders but the same counters to effect further control. The lowering of video cable potential does not affect the TV monitor (at the control site) to which the video is sent since an unmatching stage and a level restorer are provided in series between the level-lowering circuit and the monitor.
