Title: Control of rolling of a material
IPC: B21B37/66
Filed: 1971-05-28
Abstract: 1355534 Controlling roll gap SIEMENS AG 28 May 1971 [30 May 1970] 18114/71 Heading G4H The roll gap of a rolling mill is controlled in response to roll force signals which exceed a stored value related to the eccentricity of the rolls and other stand imperfections, which is determined by measuring the force while the rolls are run in contact with each other under their nominal load. The outputs of two force transducers 4 are combined at 3 and amplified at 2. Increasing and decreasing values are detected by respective devices 5, 6 and converted into respective pulse trains at 7. Feedback is provided by a forward/backward counter 8 and a d/a converter 9. The output pulses from 7 pass to an undisclosed logic circuit 10. During the measuring phase they are gated by a signal t 0  to two counters 11, 12; 11 counts upwards only and 12 up and down but not below zero. It is stated that at the the end of the measuring period 11 will have a count which represents the difference between the maximum and minimum forces due to imperfections. During rolling 12 operates continuously and its count is compared at 13 with that stored in 11. When 12 exceeds 11, showing excessive rolling force, the roll gap is decreased, and when 12 drops to zero the next backward counting pulse, detected at 14, (showing an insufficient force) the gap is increased. In an alternative (Fig. 3, not shown) the stored value is converted to an analogue value which provides additional feedback to amplifier 2.

Patent GB-358881-A (GB)
Title: Improvements in and relating to the manufacture of cellulose acetate
IPC: C08B3/06
Filed: 1930-06-16
Abstract: When carrying out the acetylation of cellulose in stages by the introduction in succession of at least four acetylation baths, the earlier stages of the acetylation are effected with the aid of a strong acid catalyst such as sulphuric acid with or without the addition of halogen, and the later stages of the acetylation are effected after the introduction of a reagent capable of reducing the catalytic power of the sulphuric acid &c.  The composition of acetylation baths with respect to acetic anhydride and sulphuric acid is so chosen as to give at the completion of the first two or three stages an acetate containing 10-15 per cent acetyl groups; and in the later baths the sulphuric acid is omitted, and in at least one of these the reagent for the partial neutralization of the sulphuric acid is introduced; and the temperature is maintained between 18-26 DEG  C. during the earlier stages, between 25-40 DEG  C. during the intermediate stages, and preferably between 40-50 DEG  C. during the final stage.  Suitable reagents are the salts of feeble acids with strong bases such as sodium or potassium acetates, and sodium lactate or benzoate, although the neutral sulphates of sodium and potassium may also be employed.  The salts are added in solution or suspension in acetic acid.  Quite small quantities of the salts suffice.  The acetylation is preferably carried out in cylindrical acetylators provided with a water jacket and rotated about an axis perpendicular to its axis of symmetry.  In an example, cotton is before subjection to the acetylation process, softened by treatment in the acetylator with acetic acid vapour as described in Specification 303,135; and at the completion of the acetylation when the mass is uniformly dispersed, the temperature is maintained at 35-40 DEG  C. until the viscosity of the cellulose acetate has fallen to the desired value; thereupon the product is saponified in the manner described in Specification 303,135, [Class 2 (ii), Cellulose &c.].
