Title: Method of grinding and attachment for grinding mills
IPC: B02C4/04
Filed: 1921-10-24
Abstract: 182,730. Winslow, H. F. Oct. 24, 1921. Roller mills.-In a grinding-mill comprising a series of rolls adapted to operate in sequence upon the material, the material adjacent the ends of a later roll is automatically removed therefrom, and deposited on an earlier roll of the sequence. The operation is performed by a pair of devices spaced apart from one another longitudinally of the later roll of the sequence and adapted to collect the material from the end portions only of the roll and re-feed it to the earlier roll. Between the second and third rolls 2, 3 of the mill and at each end of them is secured a housing 18 of inverted U-shape, the legs of which are curved concavely as shown at 19 to fit the surface of the rolls 2, 3. Adjustably hinged to a bar 32 within the housing is a scraper 30 reaching almost to the meeting point of the rolls and pressed against the roll 3 by a spring 35 adjustably held on a screwed rod 36 between a non-rotatable nut 38 and the top of the scraper. The scraper throws the material on to the roller 2 which carries it back to the first roller to be reground, the sides of the housing preventing it from moving to the ends of the rolls.

Title: Improvements in the laundering of garments of articial filaments
Filed: 1946-09-23
Abstract: 617,291. Washing clothes. BRITISH CELANESE, Ltd. Sept. 23, 1946, No. 28475. Convention date, Oct. 19, 1945. [Class 138(ii)] A process for laundering a mixture of garments of cellulose acetate filaments with garments of viscose filaments comprises subjecting the washed garments to hydro-extraction in order to remove a portion of the water content, then to the action of hot humid air to reduce the water content of the cellulose acetate garments to that desirable for hot-pressing the garments or like finishing treatment, and, thereafter, hot-pressing the garments. Preferably, the second water-reducing step takes place in a drying tumbler provided with a jet through which the hot humid air is injected. The water content of the cellulose acetate garments is preferably reduced in the first hydro-extraction step to about 75 per cent based on the weight of the goods, and to about 2 to 8 per cent by the action of the hot humid air; the corresponding reductions in the water content of the viscose garments would be to 125 per cent and 60 to 65 per cent respectively.

Title: Improvements in or relating to liquid pressure operated presses
IPC: B30B15/16
Filed: 1954-10-12
Abstract: 775,694. Hydraulic presses. HARE, Ltd., P. J., and HARE, P. J. Nov. 24, 1955 [Oct. 12, 1954], No. 29384/54. Class 69 (2). [Also in Group XXIV] An hydraulic press for light work has the press ram brought into contact with the work by a spring. A pump 18 is disposed in a reservoir 17 and supplies liquid through a valve 23 to a press cylinder 15 above or below a ram 16, therein to apply the working pressure to the ram or to retract it. A spring 35 brings the rani rapidly into contact with the work, liquid additional to that supplied by the pump being drawn from the reservoir 17 through a conduit 41 and non-return valve 42. The ram 16 is guided in an extension 25 of the lower wall of the reservoir, and the stroke is limited by the contact of an adjustable nut 49 with this extension. A plate 56 is clamped to the lower end of the ram, is guided between pillars 12, and carries a yoke 57 having pins 58 engaging the upper sides of a pair of links 59 which are pivoted at one end to the press frame and at the other end to a vertically movable guard 61. A second pair of links 62 connect the guard to a shaft 63 which carries an arm 64 contacting a plunger 65 of the valve 23. When the guard 61 is pulled down, the last part of the movement depresses the plunger 65, thus connecting the upper end of the ram cylinder to the pump and the lower end to the reservoir. The ram is thus moved into engagement with the work by the spring 35, the pressure then building up to the working value determined by a relief valve 44. When the working stroke is completed the guard is lifted manually, the initial part of the movement allowing the plunger 65 to rise, changing over the valve 23 and causing liquid to be admitted to the lower end of the cylinder 15 to raise the ram.
