Patent ES-343701-A1 (ES)
Title: Waste Gas Dust Filtration
IPC: B03C3/88
Filed: 1967-08-01
Abstract: Dust is removed from unburnt waste gas in an oxygen-blowing steel-making process, by passing gas through an electrostatic precipitator which has tubular collector electrodes 3, Fig. 1, associated coaxial discharge electrodes 4, an inlet pipe 1 and an exit pipe 7, with an exhaust fan 8. A gas-tight connection between the electrodes 3 and a top part 10 is provided by liquid-filled cups 12, 13. Dust is shaken into a space 2 by vibration of pistons 18 and conveyed by a paddle wheel 21 to a worm conveyor 22 and pocket wheel 23. To prevent danger due to explosive gas mixtures in the precipitator derived from the oxygen steelmaking process, the oxygen supply is withdrawn from the refiner if the fan 8 fails, and an injector nozzle 27 is switched in to force the gas quickly through the filter. The energizing current for the electrodes .is switched off by a switch 30. In a second embodiment, dust is removed from the electrodes by sprays 45, Fig. 3, and removed from the bottom of a water bath 43 by a paddle wheel 44.

Title: Compressor lubrication arrangement
IPC: F25B31/00
Filed: 1967-10-07
Abstract: A fluid compressor comprises compressor means in a crankcase 12, a lubricant pump 50 supplying lubricant to the compressor means, and a lubricant sump 24 separate from the crankcase. To start the compressor 10, switch 80 is closed and a solenoid valve 72 in passage 70 opens to allow passage of gas from crankcase 12 into sump 24 to equalise the pressures. Time delay mechanism 84 then closes switch 85 to start the compressor. Oil pump 50 is driven by crank-shaft 20 and draws oil from sump 24 through line 56 with check-valve 58, and supplies it through passage 60 to bearings 42, 43 &c. Oil which accumulates in crankcase 12 is carried into sump 24 via passage 70 by gas leaked from piston 30, the gas then passing via passage 74 with check valve 75 into the piston cylinder 28 of the compressor. To shut down the compressor switch 80 is opened, thus closing valve 72 which, with valves 58 and 75, prevents flow of gas into the sump 24 while the compressor is inoperative.

Title: Domain propagation arrangement
IPC: G11C19/08
Filed: 1969-11-06
Abstract: In a magnetic storage device in which information is propagated by moving a single wall domain D in a sheet of magnetic orthoferrite material 11, Fig. 2, the magnetic bias field required to maintain the domain size constant is established by providing sheet 11 with permanently magnetized surface layers 21, 23. The sheet and surface layers have a common direction of magnetization normal to the surfaces, and the moving domain is oppositely magnetized. Rare earth orthoferrites such as TbFeO 3 with 1% Bi are suitable materials for sheet 11, and the surface layers may be formed either as thin, strained regions or by deposition of a different material such as magnetoplumbite. In Fig. 1, a region R of positive magnetization is established in sheet 11 by a D.C. conductor 13, the sheet and surface layers being magnetized in the negative direction. By pulsing hairpin conductor 14, a single wall domain may be separated from region R and propagated along the sheet by pulses applied to looped conductors l1-ln. When a domain arrives at loop ln, it is collapsed by an interrogate pulse in loop 16, and the collapse is read out to a utilization circuit 19 by a loop 18, a control circuit 20 providing synchronization for domain separation, propagation and interrogation. Further propagation channels may be provided by the addition of extra sets of conductors.

Patent ES-423714-A1 (ES)
Title: Operating mechanism for slidable gates and method of operating slide gate
IPC: B22D11/18
Filed: 1974-02-28
Abstract: An operating mechanism for slidable gates which are used to control flow of liquid from a bottom-pour vessel, and a flow-controlling method. The mechanism is particularly useful for controlling teeming of liquid steel from a tundish into a continuous-casting mold. Most slidable gates either fully open or fully close the outlet of a vessel. The present invention enables the outlet to be partially open, whereby the stream discharging therefrom can be throttled. The mechanism includes a main drive means for pushing gates from a ready position to a slow-motion region under the vessel outlet. The slow-motion region of an orifice gate extends at least from a position in which the vessel outlet is partially open to a position in which it is fully open. An opposed auxiliary drive serves to retard movement of a gate as soon as it reaches the slow-motion region. Thereafter, the main drive pushes an orifice gate slowly and under close control to any desired teeming position within the slow-motion region. The mechanism also includes an improved arrangement for conducting gases to the nozzle at the vessel outlet to prevent skulls from forming, and an improved means for attaching a pouring tube to its holder.

Title: Method of making a slip joint
IPC: F16C31/02
Filed: 1976-08-03
Abstract: A slip joint including telescoped inner and outer members having substantially unstressed plastic material interposed therebetween. The joint is made by first telescoping inner and outer members with the plastic material interposed therebetween.
