The yarn feed speed may be 1.2 to 4 times the belt speed, and the roll speed may be 1.5 to 20 times, the belt speed. During setting, the yarns may be heated to a temperature greater than 212‹F, and to achieve this the roll may be maintained at 250‹F to 450‹F. In a first embodiment, Fig. 1, yarns 3 are fed onto roll 7, the yarn filaments are differentially shrunk while moving distance A-B on the roll due to different contact with the roll, the yarns are then folded in a zone between the roll and belt 15, the heated roll sets the folds, and the yarns are cooled by room-temperature air in zone 22. Air jets and cold rolls may also be used for yarn cooling. Alternatively, Fig. 2, the zone between the roll and belt is shorter, and the setting may be continued by heater 42. The belts may be of cotton or polyester fabric, and metal rolls with a matt finish may be used. The yarns may be of polyamides, polyesters, polyolefines, polyurethanes and cellulose acetate.

Abstract: 150,959. Naamlooze Vennootschap Suikercultuur Maatschappij, (Assignees of Almerood, T. G. A.). Sept. 9, 1919, [Convention date]. Roller mills.-Sugar-cane mills are provided with automatic apparatus for recording and directly indicating the clearances or distances between the rolls, the movements of each of the bottom rolls relatively to the top roll being inscribed upon a paper drum driven by clock-work, whilst at the same time the clearances are indicated by a meter. A fixed adjustable disk a mounted on the free end of each bottom roll is surrounded by a divided adjustable ring f carrying rods g which are adapted to slide in hollow rods h carried by the rings f of a similar disk a on the top roll. A plate carrying an indicator drum m and a scribing-device n is secured to the rods g by means of adjustable plates i and screws j. As the distance between the rolls increases, the rods g move out of the rods h and an arm p on one of the rods h operates the device n. At the same time, a rod o carried by the plate l moves the lever s of a meter r mounted on a cross-member q connecting the rods h. The meter r indicates the actual clearance between the rolls.

Patent GB-970654-A (GB)
Title: Continuous sugar boiling
IPC: C13B30/02
Filed: 1961-07-24
Abstract: Sugar boiling is effected continuously in a number of stages connected in series, in which the quality of the massecuite is controlled by varying the amount of vapour supplied to, the pressure existing in, and the amount of thickened juice added in each stage so that the degree of saturation in the liquor flowing from each stage to the subsequent stage is constant, and in which the conditions obtaining in each stage are chosen so as to provide overall crystal growth.  The initial stages are carried out under closely controlled substantially constant conditions of fast very low head boiling with good circulation to avoid conglomerate growth and the later stages include the positive displacement of the massecuite. An operational example is described.

IPC: C11D3/36
Filed: 1962-07-12
Abstract: The invention comprises alkali-metal starch phosphates containing 6-12% by weight of molecularly bound phosphorus in the form of phosphate.  The phosphates are made by mixing at 40-70 DEG C. an aqueous alkali-metal phosphate solution, pH 4-6.5, saturated or almost saturated at 40-70 DEG C., with an amount of starch not exceeding half the weight of phosphate solution, separating and drying the phosphate-soaked starch, and heating it, optionally in vacuo to 120-170 DEG C. for at least 2 hours.  A preferred phosphate solution contains 55-65% of sodium orthophosphate (calculated as anhydrous salt). In an example, an aqueous solution of NaH2PO4.2H2O and Na2HPO4.7H2O at 80-100 DEG C. is cooled to 55 DEG C., corn starch is added, and the resulting slurry stirred at 40-50 DEG C. The filtered residue is heated in vacuo at 150-155 DEG C. for 10 hours, yielding a sodium starch phosphate containing 9.6% of phosphorus.
