Abstract: ABSTRACT A device for introducing gases into metallurgical vessels comprising a refractory brick of low gas permeability which is surrounded along its length by a metal shell shaped to leave one end of the brick exposed and at the other end to define a gas collecting space which communicates with a gas inlet. The device incorporates refractory ceramic fibres, e.g. in the form of a mat, extending along its length and positioned either around its periphery and/or through its interior which afford one or more gas passages communicating between the gas space and the free end of the brick.  In use, the device is removably located in the refractory lining of a metallurgical vessel by means of mortar with its exposed end directed towards the interior of the vessel and the gas connection accessible from the exterior of the vessel.

Abstract: ABSTRACT OF THE DISCLOSURE        An actuating system for a valve arrangement is disclosed, in particular a stable valve system for controlling the flow of fluids through an opening. The valve system is activated by and in response to controlled rapid actuation but is not responsive to slow uncontrolled movement or random actuation.  The valve actuating system includes a follower disposed adjacent to but separated from the actuating device by viscous material.  The actuating system includes an actuating device having a force transfer surface portion which has a normal rest position, but can be driven and caused to move.  The follower portion of the actuating system, which may be a valve stem or a portion of a valve stem, will be adjacent to, but separated from the force transfer surface portion of the actuating device.  The viscous material is in contact with both the force transfer surface and the follower.  The viscous material allows almost immediate and complete transfer of rapid movement and force from the force transfer surface of the actuating device to the follower, but as long as they are not rapid, the material will absorb relatively large drifts and shifts in the actuating device and support structure without causing any substantial shifts in the follower or stem.
