Title: Closure device for the bottom outlet opening of a casting ladle
IPC: B22D11/10
Filed: 1969-06-17
Abstract: In a casting ladle 2 incorporating a bottom pour nozzle 3 supported by a holding ring 7 and disc 8 firmly connected to the ladle casing 6, the opening and closing of the ladle discharge opening is controlled by movement of a slide plate 10 kept in tight sealing engagement with the disc 8. The slide-plate is carried by a frame 12 pivotally mounted at 131 for rotation about a horizontal axis 15 in bushes of a two-arm flexible lever 40. A ball and socket arrangement 22, 23 mounts the lever 40 on to a bracket 20 which is secured to the ladle casing 6. The ball pin 22 can be screwed in to pretension the lever 40 to ensure that the slide plate is urged upwardly against the disc 8. Alternately (Fig. 4, not shown) the bracket may be resiliently mounted on the ladle. The lever is rotated between its open and closed positions either by means of an hydraulic piston 28 or by manual displacement (Fig. 5). In an alternative embodiment (Fig. 6, not shown), the two-arm lever is replaced by a onearm flexible lever (41).
Patent ES-377239-A1 (ES)
Title: Igniter facility
IPC: F23Q9/04
Filed: 1970-03-07
Abstract: An igniter for multi-unit gas burners comprises an igniter tube which extends transversely to all the burner units, and which has an ignition aperture near each burner unit, an ignition electrode at one end of the tube, and an electronic flame detector at the other end. Figs. 1 and 2 show an appliance comprising a number of Bunsen burners 1, and having an igniter tube 5 with ignition apertures 51. When a solenoid valve 7 is opened, gas flows into the igniter tube 5 by an ignition line 8, and is ignited by an igniter electrode 14 at the apertures 51 adjacent to the electrode. The "strip" of flame flows along the igniter tube to a detector electrode 15 of an electronic flame detector, which opens the solenoid valve 10 to allow gas to flow into the main burner units 1. The gas-air mixture is ignited at the ends 11 of the burners nearest to the igniter tube. Should the "strip" of flame in the igniter tube fail to reach the detector electrode 15, the gas supply through valve 7 is interrupted. Use of a similar igniter tube with a non-atmospheric lattice type burner is also described (Figs. 3 and 4, not shown) in which the igniter tube may extend along the distribution tube (16) of the burner units (17).

Patent ES-412051-A1 (ES)
Title: Minimum scale reheating furnace and means relating thereto
IPC: C21D1/52
Filed: 1973-02-24
Abstract: A ferrous work reheating furnace wherein high fuel efficiency is achieved with minimum scale formation. The work is initially heated in an atmosphere which is slightly oxidizing, the work being in a temperature range where scale formation does not readily occur. The work is then placed in a slightly reducing atmosphere after it reaches a predetermined elevated temperature. A unique arrangement is provided wherein a continuous reheating process takes place utilizing a protective atmosphere generated by hot air burners during the high temperature phase. These burners have a low air to fuel ratio and the gases are caused to flow toward the location where the work is introduced. The combustibles within the gases are combusted through the introduction of air into the portion of the furnace nearest the charge end. Additional efficiency is gained by using the spent gases to preheat combustion air for the burners.
Patent ES-422865-A1 (ES)
Title: Capstan detacher
IPC: B23Q7/00
Filed: 1974-01-25
Abstract: The detacher disclosed comprises a web infeed including the usual guides and tension brushes and pin-feed tractors. The usual high-speed pull roll sets are employed to effect the severance of the successive forms and the forwarding of them to the delivery conveyor or other depository. However, no low speed gripper or jump rolls are employed, the arrangement being such that sufficient retardation of the web for the bursting of the forms is furnished by the tractor and infeed members. This eliminates the necessity for providing timing means for starting the form web in a specified position, cams, change gear assemblies, vernier's, etc. A simple motor-driven belt guided by idler pulleys is employed for all of the driven parts. The actual burster instrumentality comprises a novel quick switch-over blade and pressure roller unit for alternative use with paper webs and tab cards. An abrasive covered roll may be employed between the infeed assembly and the point of severance to give some slight snubbing action on the web, especially in the case of light-weight papers. It also, in such cases, can remove some tension from the tractor pins.
