Patent BE-895357-A (BE)
Title: Continuous casting of metals - with heated mould and cooled dummy bar
Inventor: OHNO ATSUMI
IPC: B22D11/10
Filed: 1982-12-15
Abstract: Continuous casting of metal is carried out in such a way that its pressure at the exit from the mould is virtually zero, i.e. between 0 and 0.002 kg/cm2. The mould is heated so that its inner surface is above the temperature of solidification of the cast metal. The dummy bar, closing the base of the mould, is spray cooled to below that temp. The outer skin on the cast metal only solidifies as the bar is withdrawn, and it leaves the mould. Process can be used to cast vertically, upwards or downwards, or horizontally, for a variety of shapes. In conventional continuous casting with a cooled mould the outer skin of the cast metal solidifies first. Friction with the mould causes defects in the metal surface and molten metal from the core can break through the skin. In this method it is claimed that the outer surface remains smooth, and free from defects, making scaling almost unneccessary.

Abstract: A B S T R A C T   While good oil-repellency can be imparted to fibre materials by treating them with polymers containing perfluoralkyl groups, it is difficult to impart water-repellency to the fibre materials at the same time and also give the treated materials good handling qualities of, for example, moisture content and texture.  This is achieved by treating the fibre material with, besides the perfluoralkyl group-containing polymers, an addition product of a) an unsaturated compound which is an olefin, a vinyl or allyl ester of an aliphatic straight or branched chain acid, a vinyl ether whose alkyl radical has at least 4 carbon atoms, an allyl ether whose alkyl radical has at least 4 carbon atoms and/or a vinyl halide with b) an organopolysiloxane which contains hydrogen atoms bonded to silicon atoms, the addition product con-taining on average more than 7 carbon atoms in the alkyl radical and at least 0.20 mole of the unsaturated compound component a) per gram atom of hydrogen in the siloxane component b).

Abstract: ABSTRACT                A technique is provided for raising the heating value of the off gas product of a retort in which oil shale is being retorted.  Such a retort containing oil shale particles is ignited and air is passed through it for combustion with carbonaceous material in the oil shale to provide heat for retorting the oil shale.  Typically the off gas withdrawn from the retort may have a heating value of about 20 to 25 BTU/SCF (180-220cal/litre).  In the process of the invention a small amount of water is introduced into the retort so that the water gas reaction occurs on contact with carbonaceous material in hot shale. Heating value of the resultant off gas can increase to ?? BTU/SCF (???cal/litre) or more, due to the added hydrogen and carbon monoxide products of the water gas reaction.

Abstract: Title of the Invention DUAL MOTOR WEB MATERIAL TRANSPORT SYSTEM          Abstract of the Disclosure A ribbon drive and motor control system in which the instantaneous speed and torque output of a pair of motors are controlled interdependently to bidirectionally transfer ribbon or other web material between a pair of storage reels mechanically coupled to the motors at a uniform ribbon velocity and tension.  The motors are electrically excited in series to rotate in the same direction with the back electromotive force of one motor being used to vary the instantaneous excitation voltage applied to the other motor, while drag from said other motor is imparted to the ribbon to control the speed of the first motor.  Compensation for variation of the radii of ribbon on the reels during operation is accomplished automatically by variation of motor torque and velocity to minimize variation in ribbon tension and ribbon velocity.  A bridge switch actuated by signals initiated by electrical contacts near the ends of the ribbon causes the motors to reverse direction.  The system results in longer ribbon life, improved tracking and increased speed capability in an impact printer without complex servo controls.

Abstract: ABSTRACT OF THE DISCLOSURE Disclosed is an electrolytic diaphragm cell having a plurality of fingered anode blades extending outwardly from an anode base plate and cathode means that are electrically and mechanically connected to a cathode base plate that is parallel to and spaced from the anode base plate.  The cathode means include a cathode back screen spaced from and parallel to the cathode base plate, and a plurality of hollow cathode fingers extending outwardly from the cathode back screen, and interleaved between the anode blades.  Each of the cathode fingers has an open base and side walls, a top, a bottom, and a leading edge fabricated of foraminous metal.  The in-dividual cathode fingers have bolt means electrically and mechanically con-nected to each of the cathode fingers, and extending outwardly from the open end thereof.  The bolt means pass through apertures in the cathode back screen corresponding to but of greater diameter than the bolt means so that the individual cathode fingers are slideably adjustable on the cathode back screen.  Electrical contact between the cathode base plate and the cathode unit is provided by first elastic conductor means which extend outwardly from the cathode base plate toward the cathode back screen, and second elastic conductor means in electrical contact with the first elastic conductor means and in electrical and mechanical contact with the bolt means on the opposite side of the cathode back screen from the cathode fingers.  Also disclosed is a method of assembling the cell by inserting the individual cathode fingers between adjacent individual anodes such that the bolt means project outwardly from the open base, positioning the cathode back screen on a plane substantially defined by the open edges of the individual finger cathodes while allowing the bolt means to pass through apertures in the cathode back screen.  The elastic conductor means are then placed on the bolt means on the opposite side of the back screen from the cathodes.  The elastic conductor means, the bolt means, and the cathode back screen means are then fastened together; and the anode unit and the cathode unit are assembled together so as to form a single electro-lytic diaphragm cell.
