Abstract: Device for improving the heating of a channel (2) for distribution of glass (1), said device including a cylindrical duct (6) connected at its upstream end to means (7) for feeding a premixture of air and fuel gas and whose downstream end (8) opens inside a cylindrical bore (9) in a refractory block (10) inserted in a wall (11) of the channel, said cylindrical bore (9) extending by means of a coaxial cylindrical duct (12), of smaller diameter than that of said bore, the cylindrical channel (6) being surrounded by a sealing ring (13) which covers the face of the cylindrical bore (9) in which said channel (6) is inserted.

Abstract: Two fixed heads are used to lubricate a split-mold. The heads do not interfere with the movements of the mold and are effective to inject a jet of a gas that forms a powdery carbonaceous material. When the mold is open, the injection axis of each head is just about in line with the axis of the associated half-casting.

Abstract: A method of polishing the surface of a glass article consists in exposing the surface of the said article to a flame produced by oxygen and by a fuel. In order to obtain a perfect surface quality, whatever the thickness and configuration of the article processed, while preventing any premature collapse of the article in question, use is made of a flame such that the thermal energy originating from the transfer of heat by convection exceeds the thermal energy originating from the transfer of heat by radiation, and preferably of a flame of the oxygen-hydrogen type.

Abstract: The present invention concerns a process for producing a food product imitating the appearance of marbled meat. The food product according to the invention is obtained by the mixture of at least two compositions of different color, of which a first imitates the color of lean meats or of offals and a second imitates the color of fat, the consistencies preferably also the elasticities of the compositions at the moment of mixing being different from one another. The consistencies preferably differ by from 20 to 700 Brabender units when measured at the same temperature. The use of compositions of different consistencies enables simple mixing or blending techniques and conventional apparatus to be used to obtain the desired random marbling effect. Particularly good results are achieved by incorporating a stiffening or texturizing agent such as wheat gluten. Preferred embodiments of the product comprise protein materials and are stable semi-moist products.
