Abstract: A heat-insulating panel 11 (e.g. for insulating the ceiling 35 of a furnace) is made by disposing a metal supporting member 15 adjacent to felting screen (27), Figure 4 (not shown), to lay down a wet refractory fiber mat 13 from an aqueous, refractory fiber-colloidal silica mixture about the metal member. The member 15 has a central base section and a pair of wings extending in opposite directions from opposite edges of the central section, with the wings being disposed at an angle of between about 130 DEG  and about 80 DEG  to each other and each containing a plurality of holes. After drying, the member 15 is embedded within the mat 13 with individual fibers extending through the holes and firmly anchoring the member. The member is located adjacent the rear surface of the heat-insulating panel, and its central section contains an aperture through which a support rod is passed to mount the panel. <IMAGE>

Title: Modified twin stand control system
IPC: B21B37/52
Filed: 1978-11-29
Abstract: Errors in the width of stock rolled in a train of mill stands are detected and the rotational speed or the roll separation of one mill stand adjusted to vary interstand tension in a sense to minimise the detected errors in the stock width. The roll separation or roll rotational speed, respectively, of at least one other mill stand of the train is subsequently adjusted in a sense to minimise the interstand tension caused by the adjustment to the first-mentioned mill stand. The stock has substantially equal width and height dimensions. In the figure, 8 measures the height for control of the gap of stand 2 and the width for speed control via "conditioner" 13, limiter 14 and "set point controller" 15.6 measures interstand tension and also controls speed via 15; it also controls the gap of stand 1. "Back tension" is measured at 21 and controls the speed of both stands. No circuit details are disclosed. <IMAGE>
Patent GB-2009034-A (GB)
Title: Crimped hollow fibers for fluid separations, bundles containing the hollow fibers, and apparatus and process for separating fluids
IPC: D02G3/22
Filed: 1978-11-29
Abstract: Hollow, semi-permeable fibers which are intended for use in fluid separations have crimps with amplitudes up to 50% of the external diameter of the fiber and an average crimp period of less than 5 cms. The fibers are sufficiently rigid to retain its crimp form during fluid separation. Preferred fibers have an outside diameter of 150-800 microns, a wall thickness of 50-200 microns and a crimp amplitude of 15-250 microns. The tensile modulus is at least 40 kg/mm<2>. The relatively low amplitude crimps enable good fluid dispersion through a bundle comprising substantially parallelly-oriented hollow fibers such that shell-side (i.e., the exterior sides of the hollow fibers) feed of the fluid mixture to be treated can be attractive, even when the flow of the feed is predominantly axial to the hollow fibers. Shell-side feed of the fluid mixture to be treated is often particularly advantageous since the fluid mixture can frequently be recovered from the fluid separation with a relatively low pressure drop.
