Abstract: 1,106,773. Shrinking fabrics. PASOLDS Ltd. 23 Nov., 1966 [18 Nov., 1965], No. 49005/65. Heading D1S. In a fabric shrinking machine comprising two conveying means each having a portion adjacent to a portion of the other means and the speed of one of the conveying means being greater than that of the other means, the fabric is held in contact with the conveying means immediately before and after 'passing between the adjacent portions by applying a pressure differential across parts of the conveying means.  In the drawing accompanying the provisional Specification, the fabric q in the form of a knitted tube passes over a stretcher s in a chamber o to which steam is supplied to render the fabric compliant. Heated rolls b. c convey the fabric into a chamber a where it passes around perforated oppositely-rotated rollers d, e, the roller d being driven faster than the roller e. Channel casings g, having a substantial degree of internal vacuum and baffles h, k are provided in the rollers d, e, respectively. Spaces i, m in the rollers d, e are maintained at a low degree of vacuum. Steam may be supplied to the space n within the chamber a. The compacted fabric passes around a batching-up roller f driven at the same speed as the roller e. In the drawing accompanying the complete Specification, the tubular fabric, whilst on a stretcher 3, passes between rollers 1, 2 and through a steam box 4 having a steam tube on each side of the fabric. The fabric then passes around perforated oppositely-rotated rollers 5, 8 having suction ducts 6, 9 defined by baffles 7, 10, respectively, the roller 8 rotating at a slower speed than the roller 5. Hot air from a heater to dry the fabric is directed on to the fabric as it is held in' contact with the roller 8. The compacted fabric then passes over a roller 11 onto a conveyor 12. In a third embodiment (not shown), the rollers are replaced by permeable belts, each belt having a portion extending adjacent and parallel to the other belt.

The blocking agent can be phenol, cresol, ethyl acetyl acetate, cyclohexanone oxime or isopropanol.  In an Example (1) oxypropylated trimethylolpropane was reacted in a first stage with a deficiency of tolylene diisocyanate to form a hydroxy terminated intermediate which was treated with more tolylene diisocyanate to form an isocyanate terminated intermediate which was diluted with 2-ethoxyethyl acetate and toluene and blocked with phenol.  The blocked intermediate was then mixed with an imine of formula <FORM:1031917/C3/2> in the presence of the above-mentioned solvents.

Title: A Method of and an Apparatus for Determining and Correcting Slipping in a Reversing Rolling Mill.
IPC: B21B37/46
Filed: 1967-11-10
Abstract: 1,163,059. Automatic speed control. SIEMENS A.G. Nov. 10, 1967 [Nov. 12, 1966], No.51245/67. Heading G3R. In a reversible rolling mill, the relative speed between the material 1 and work rolls 2, 3, is detected, and the speed of the rolls is reduced if the slip becomes excessive. The rolls are driven by motors 4 whose speed is indicated by a pulse generator 7. The passage of an end of the material 1 is detected by devices such as photo-cells 9, 10, supplying signals to counters 11, 12, which are set thereby to a number representing the distance between each cell and the next cell in the rolling direction. The counters are counted back by the pulse generator 7, lag and lead units 13, 14, being provided to compensate for the difference in speeds of the material entering and leaving the rolls. When the work rolls skid on the material, which is then not moved forward, the pulse generator causes one of the counters to be set back to zero and a signal is applied to controller 15 for reducing the rollspeed by a set amount. In addition, the counters are re-set to the last reading they showed before they were counted down to zero. After such speed reduction, if one of the counters is again set back to zero, the driving speed is further reduced by a set percentage. Alternatively, if after slipping has occurred, one of the counters is set to a new value by one of the photo-cells, the reference valve for the speed is again raised to the original valve in a stepped manner. After the rolls have skidded a number of times over a section of material corresponding to the distance between two adjacent photo-cells, the speed is not raised again. Each counter 11, 12 has an auxiliary counter which actuates a digital-analogue converter after a number of zero signals. This converter operates to maintain the reduced speed until the end of the pass. In order that the desired speed value may be reduced rapidly in the region where the photo-cells lie furthest apart, a pressuredetector 8 is connected to a threshold-valvesignalling device 16, whereby the controller 15 receives a signal corresponding to a zero reading on one of the counters when the rolling- pressure is zero.
