Patent GB-822046-A (GB)
Title: Improvements in or relating to rosin size and use of same in sizing paper
IPC: D21H17/62
Filed: 1956-08-23
Abstract: Rosin size is made by subjecting a rosin material to a topping operation to remove from about 2.5% to about 20% by weight of light oils and saponifying the product with alkali.  The removal may be effected by distillation, or fractionation under reduced pressure. Suitable starting materials are wood rosin, gum rosin, tall oil rosin, and modified (e.g. hydrogenated or disproportionated) rosins, which may be refined or unrefined. The topping may be supplemented by heat treatment before, after, or simultaneously, in which the material is heated for from 5 minutes to 4 hours at a temperature of from 260 DEG  C. to 325 DEG  C. The rosin is converted to size by heating with aqueous sodium or potassium carbonate at 190-212 DEG  F. or by reaction with sodium or potassium hydroxide, and the product added to a paper-making system in an amount of from 0.25% to 5% of the dry weight of the pulp.

Abstract: 225,672. Jorkhoff, H. W. Oct. 19, 1923. Locking by frictional detents. - The existing brakes of a vehicle are applied automatically upon movement of the vehicle in a reverse direction by means of a drum or ring connected to the brakes and adapted to be carried around to a limited extent with the vehicle wheel by the engagement of an arm or lever on the drum with the wheel spokes. As applied to the steering wheel of a vehicle a drum 8 mounted upon the vertical pivot 1 of the stub axle so as to be capable of limited rotary movement determined by slots is connected by a cord 19 to the existing operating lever 5 of an internal expanding brake acting upon the drum 4 mounted on the wheel. The drum 8 has pivoted thereon at 13 a bell-' crank lever 14, 16 adapted for engagement with the wheel spokes. The arrangement is such that as long as the wheel is turning in a direction opposite to that of the arrow 15 the arm 16 engages the wheel spokes and the device is inoperative but should the wheel commence to turn in the opposite direction the arm 17 swings into engagement with the spokes as indicated in Fig. 8 and the drum 8 is thereby turned to apply the brakes bv the cord 19. The lever 14, 16 may be locked in an inoperative position when desired. In the modification shown in Fig. 10, a pair of these levers is mounted upon diametrically opposite pivots 13 on the drum 8 so that the automatic operation of the brakes by either direction of rotation of the wheel may be effected. For this purpose a cord 21 additional to the cord 19 is fitted.
