Title: Improvements in and relating to casting machines
Inventor: BRAY THOMAS LEONARD
IPC: B22D11/06
Filed: 1970-02-24
Abstract: 1,249,784. Continuous casting machines. SOUTHWIRE CO. 24 Feb., 1970, No. 8813/70. Heading B3F. [Also in Division G3] A continuous casting machine having a rotatable casting wheel with a peripheral groove and a band to close a portion of the groove has a band tensioning device comprising a band support wheel 10 and a support therefor, the support being resiliently responsive to movement of the wheel 10 and including adjusting means to maintain a substantially constant tensioning force as the support responds to movement of the wheel 10, the arrangement being such that the support acts through a single point. The wheel 10 is mounted on a shaft 25 carried by a block 24 which is slidable along the guide rods 19. Also slidable along the guide rods 19 is a plate 41 having a tubular sleeve 42 within which is located a spring 58. Below the spring is a thrust plate 56 and a screw 52 driven by a motor 49. Above the spring 58 is a load cell 60 which supports a block 61 which forms part of a ball and socket connection between the load cell 60 and a member 32 fixed to the block 24. In use, the force exerted by the spring 58 on the wheel 10 is maintained constant by maintaining a constant distance between the thrust plate 56 and the block 24. Any change in this force is sensed by the load cell 60 which provides an output to cause the motor 49 to move the screw 52 and thus the thrust plate 56 either up or down until the required force is restored. Switches ULS-1 and LLS-1 limit the movement of the screw 52.

Patent GB-568051-A (GB)
Title: Improvements in the production of organic esters of cellulose
IPC: C08B3/22
Filed: 1943-06-08
Abstract: Cellulose is esterified in the presence of an inorganic acid esterification catalyst and of a solvent for the cellulose ester, and the solution so obtained is subjected to a ripening treatment, wherein the water for ripening is added in two or more stages, and the whole of the acid catalyst is neutralized before or during the ripening treatment.  The total amount of water added, excluding any that may be required to destroy unreacted anhydride, is preferably at least 60 per cent of the weight of the original cellulose.  Ripening may be effected at 60-120 DEG  C.  Sulphuric acid or phosphoric acid may be used as the esterification catalyst, and it may be neutralized by adding a substance which forms a salt which is insoluble in the esterification solution. Zinc oxide, zinc acetate, oxides, hydroxides, and carbonates of lithium, strontium, barium and aluminium, and organic salts of these metals may be used for neutralizing the catalyst. Carbonates and acetates of calcium and magnesium may be used.  The water may be used in the form of an aqueous solution of acetic acid.  The neutralizing agent may be added in the form of a solution or as a powder.  In an example, cellulose is pretreated with a mixture of acetic acid, sulphuric acid and water.  It is acetylated with a mixture of acetic anhydride, acetic acid and sulphuric acid.  Water is added to destroy unreacted anhydride.  A mixture of magnesium acetate and calcium acetate, obtained from calcined dolomite, is added in amount sufficient to neutralize the sulphuric acid, together with water for ripening the cellulose ester.  The mixture is heated for several hours and then more water is added.  The ripening is continued for a further period, and then the cellulose acetate is precipitated by the addition of a large amount of water.  The process is applicable to the production of cellulose propionates, butyrates, and other esters.
