Title: Tapered refractory bricks for lining metallurgical vessels - e.g. iron and steel ladles or converters have cylindrically curved taper faces
IPC: F27D1/04
Filed: 1975-07-23
Abstract: The brick is so constructed that the tapering surface have identical cylindrical curvature, on surface being concave and the other convex. This enables vessels of a considerable range of size to be lined satisfactorily with refractory (e.g. dolomite and/or magnesite) bricks without leaving gaping joints requiring to be specially filled later. The bricks can be made by the normal methdo of stamping, pressing, etc. A typical bricks has a foot adn which lies against the metal wall of the vessel, a head end facing the molten metal contents and the cylindrically curved side or taper surfaces. The centres of curvature of the curves lie on the dias. of the curves, which intersect on the centre plane of the disc. Any mfg. variations in the bricks are accommodated by slight rotation of the bricks round the centre of curvature of the concave face of one brick and/or the convex face of the next adjacent brick. The magnitude of the radius of curvature is a function of the thickness of the brick to be used.

Patent NL-8501635-A (NL)
IPC: H04N3/15
Filed: 1985-06-06
Abstract: To realise a camera with both an undisturbed scene recording and automatic adjustments which are periodically effected while using one and the same image sensor (1), this sensor is formed as a charge transfer device comprising a pick-up member (I), a storage member (S) and a shift register member (SR). To perform a black level setting (9, 11) in the scene picture signal an opaque strip (BS) is provided on the pick-up member (I). Automatic adjustments for, for example, lens focus (FC) and white balance (WB) in colour recording are accurately performed when the image sensor, beyond a scene picture information integration period and a subsequent charge transfer period between pick-up member and storage member, is operative with an adjustment action information integration period and a subsequent charge transfer period so that a signal is obtained at the sensor output terminal (R,G,B) with sequentially the adjustment action information and the associated dark current information for a separate black level control circuit (10, 12). The adjustment action information can thereby be accurately determined for the relevant adjustment as the own dark current information is automatically obtained.
