Abstract: Apparatus for the cold working of hot rolled steel rod comprises at least two freely rotatable pulleys (18) driven by a motor (26) for orbital revolution for imparting a substantial degree of cold working to the rod as it is fed continuously through the apparatus. The rod is twisted in one direction as it enters the pulley system and is twisted in the opposite direction as it leaves the pulley system. The apparatus operates also to descale and straighten the rod continuously and is particularly useful in the production of steel rod for welded mesh in reinforcing concrete.

Abstract: A speech recognition system in which the gain, at which the spoken instruction signal including noise transduced through a microphone (2) is amplified, is adjustably fixed at an appropriate level determined according to the smoothed background noise level obtained after a recognition switch (3) has been released but before a spoken instruction is uttered toward the microphone, in such a way that the gain is inversely proportional to the background noise level. In the system according to the present invention, it is possible to reliably detect a spoken instruction even if background noise level fluctuates intensely just before or after the spoken instruction is uttered toward the microphone. The system comprises a level detector (22), a sample holding circuit (21, a gain controller (20), in addition to a conventional speech recognizer (100).

Abstract: Crystalline silicates and processes for the production thereof are described. These crystalline silicates are of new crystalline structure, which, as determined after calcination in the air at 550°C, have a composition represented by the general formula (I): pM<sub>2/n</sub>O·Al<sub>2</sub>O<sub>3</sub>·qSiO<sub>2</sub> (the symbols are as defined in the appended claims) and give a principal X-ray diffraction pattern as shown in Table 1. They are superior in heat resistance and acid resistance, and can be used as catalysts for the conversion of various organic compounds, absorbents, or as catalysts for various reactions. They are produced by reacting an aqueous mixture comprising (a) a silica source, (b) an alumina source, (c) an alkali metal and/or alkaline earth metal source, and (d) ethylene glycol or (e) monoethanolamine at a temperature of 100 to 300°C till the desired crystalline silicates are formed. Although ethylene glycol and monoethanolamine do not remain in the crystalline silicates, they play important roles in the formation of the desired crystalline structure in the course of the production thereof.

Abstract: In order to minimise the dog-bone and fish-tail deformations of a slab (1) during width rolling, the rolling surfaces (3) of the rolling elements (8) have a radius of curvature of at least 0.6 m. The radius may be e.g. 5 m.

     Preferably the rolling elements (8) are less thick, in the direction transverse to the rolling direction, than the radius of curvature of the curved surfaces (3). They may be arcuate segments running on guide rollers (14). The segments may be flexible, the radius of curvature being determined by the positions of the guide rollers (14). The curved surface may be provided by an endless conveyor (15) running on guide rollers.
