Title: Improvements in or relating to adhesives for use in the manufacture of faced corrugated paper-board
IPC: B31F1/28
Filed: 1960-02-02
Abstract: Dimethylol-urea starch containing 0,28% of dimethylol-urea is made by heating a 32% aqueous suspension of starch to at least 115 DEG F., adding an aqueous solution of dimethylol-urea, agitating the mixture for two hours, adding soda ash to bring its pH to between 7,5 and 8,0, isolating the dimethylol-urea starch by filtration and then washing and drying it.  The aqueous suspension of starch is prepared by mixing 300 parts by weight of starch with water and adding sufficient mineral acid, e.g. sulphuric or hydrochloric acid, to bring the pH to about 4,0.  The solution of dimethylol-urea is made by dissolving 0,81 parts of dimethylol-urea in 1,66 parts of water, heating the solution to boiling point and cooling and diluting it with sufficient water to bring its volume to twice that of the said 1,66 parts of water. U.S.A. Specifications 2,407,071 and 2,838,465 are referred to.ALSO:An adhesive composition, for use, in an aqueous alkaline medium, in the manufacture of faced corrugated paper-board, comprises fully gelatinized starch and a granular, uncooked, highly cross-linked, partially inhibited, ungelatinized starch product, which does not become fully gelatinized in water, but does become fully gelatinized and highly viscous when heated, e.g. to a temperature between 120 and 200 DEG F., in an aqueous alkaline solution of borax, and is the separated dried product obtained by reacting native starch with 0,12 to 0,42% of dimethylolurea (based on the weight of starch) in an aqueous suspension having a pH between 1,5 and 7,0, which is adjusted, before separation, to between 4,5 and 10,0 (see Group IV(a)).  The adhesive composition may contain between 15 and 25% by weight, based on the total starch content, of the fully gelatinized starch, between 85 and 75% of the said ungelatinized starch product, up to 7,5% of borax, based on the weight of the ungelatinized starch product, and caustic soda.  U.S.A. Specifications 2,407,071 and 2,838,465 are referred to.

Abstract: 305,578. I. G. Farbenindustrie Akt.- Ges. Feb. 7, 1928, [Convention date]. Silicon tetrachloride. - The production of anhydrous aluminium chloride from raw materials containing both alumina and silica in the presence of a reducing agent such as carbon or carbon monoxide is carried out with chlorine charged with silicon tetrachloride vapour in such amount that no simultaneous formation of silicon tetrachloride from the silica present can take place; alternatively excess of chlorine with respect to the tetrachloride may also be used, in which case some silicon tetrachloride is formed from the silica present.

Abstract: 411,229. Distributing music &c. ECKERSLEY, P. P., 82, Swan Court, Chelsea, London, and CARPENTER, R. E. H., 35, Croham Valley Road, Croydon. Feb. 13, 1933, No. 4432. [Class 40 (iv).] In a programme distributing system, a feeder line 3 with the loud-speakers 5 bridged across it behaves like an iterative impedance network, and deleterious effects are produced due to reflection from the far end of line. To obviate this the line is terminated in a suitable impedance which at the higher frequencies is mainly resistive. As shown, the impedance comprises a resistance 6 (e.g. 500 ohms) equal to the characteristic impedance of the line 3 in series with condensers 7, 8 (e.g. each 0.1 mf.) such that their reactance at the lower frequencies is high and at the higher frequencies is low. In order to avoid cross-talk, the mid-point of the resistance 6 is earthed. Alternatively the resistance 6 may have a value from three to five times the characteristic impedance, in which case the condensers may be of smaller value or may be omitted. The subsidiary feeder lines such as 12 are terminated in a similar manner.

In a liquid sodium cooled nuclear reactor, the control or safety rods are adjusted by a spring and piston mechanism which is mounted beneath the reactor and which employs the reactor coolant. The rod is positioned by adjustment of the output pressure of the pump supplying coolant to the mechanism.
