[Class 59] Each roll of a roller mill is cooled bv water fed through an axial pipe mounted to rotate with the roll and is discharged through a thrower surrounding the water inlet end of the feed pipe. The feed pipe is attached to the thrower and a separate portion of the feed pipe extends across a water box into which the water from the thrower is discharged and is attached to a water supply branch on the water box wall. As shown, the hollow roll c is provided with an outlet d discharging into a water-box e and a water inlet pipe a rotatable with the roll and screwed into the outlet d. The pipe a is supported in the roll at intervals along its length by externally grooved collars. A short length of pipe b is screwed into the outlet d and its opposite end rotates in a gland h attached to the opposite side of the water-box e. Cooling water enters the inlet i and after passing through the pipes b, a, is discharged at the end of the pipe a into the hollow roll, and flows into the water-box e through outlet d. Perforations may be made in the pipe a near the outlet d to cool the roll in proximity to the discharge end. The pipe b may be flexible and carry a short length of pipe which enters a gland either in the discharge outlet d or on the outer side of the water-box. A common water-box may be used for the two rolls and this may be attached to the gear case of the rolls so that the rolls are interchangeable and reversible.

Title: Method of activating clays or like siliceous crude earths
IPC: B01J20/12
Filed: 1937-02-08
Abstract: In activating clays and like siliceous crude earths by the action of sulphuric acid at ordinary or elevated temperature and under atmospheric or increased pressure, there is employed, in addition, hydrochloric acid at such a time and in such quantity that gypsum formed in the course of the treatment with sulphuric acid and gypsum initially present in the earth is dissolved and retained in solution. The amount of sulphuric acid is preferably sufficient to convert the whole of the calcium present into gypsum.  The earths may be treated simultaneously with sulphuric acid and hydrochloric acid, hydrogen chloride or sodium chloride. Alternatively, the earths may be first treated with sulphuric acid and subsequently treated with hydrochloric acid, hydrogen chloride or alkali metal chloride and sulphuric acid; if desired, the earths may be separated from the liquid phase between the two treatments.  The treatment with hydrochloric acid &c. may be effected at elevated temperature, say 60--100 DEG  C.  Specifications 258,246 and 275,203, [both in Class 1 (ii)], are referred to.

Title: Improvements in or relating to devices for laterally displacing hay or the like material lying on the ground
IPC: A01D78/00
Filed: 1956-02-07
Abstract: 830,373. Haymaking machines. VAN DER LELY N.V., C. Feb. 7, 1956 [Feb. 11, 1955], No. 3804/56. Class 6(3). A device for laterally displacing material lying on the ground has at least one raking member mounted on a support or supports which is or are so fixed to the frame of the device as to be rotatable about a non-vertical axis which makes an acute angle with the axis of rotation of the associated raking member. In the device as illustrated in Fig. 1, rake wheels 34 are mounted on a frame 1 by means of bent axles 22 rotatably mounted in tubes 14 fixed on the frame. The rake wheels 34 are so positioned that when the device is towed in the direction V, it acts as a side delivery rake delivering to the left. Each axle is held against rotation by means of a pin 28 engaging holes in a disc 31 on the axle and in lugs 26 on the tube, but on withdrawing the pin 28 from the disc 31, the axle 22 can be rotated through 180 degrees, thus bringing the wheel into the position 34A and converting the device into a tedder. If the shape of each axle is modified to decrease the angle between the longitudinal axis of the hub of the corresponding rake wheel and the axis of the tube 14, then inversion of the axles through 180 degrees in their respective tubes 14 brings the rake wheels into the positions indicated in chain lines in Fig. 1, whereupon the device becomes a side delivery rake delivering to the right when towed in the direction R. In the modification shown in Fig. 3, the rake wheels 66 are mounted on cranks 63 rotatably mounted in bushings 60 formed integrally with bushings 53 mounted on axles 51 carried by the frame of the device. In this case, the bushing 53 is held against rotation by means of a pin 57 mounted on the frame member 50 and engaging one of two pairs of projections 56 provided on opposite sides of the bushing 53, and by releasing the pin from one pair of projections, rotating the bushing 53 through 180 degrees and reinserting the pin between the opposite pair of projections, the wheels may be moved to the positions 66A, after which the device acts as a tedder. In either position, the wheels can adapt themselves to any unevenness of the ground by virtue of the fact that the cranks 63 are rotatably mounted in the bushings 60, their movement in this respect being controlled by springs 76 fixed to lugs 77 on a bar 78. The bar 78 is rotatably mounted in bearings 79 carried by the frame member 50, and by rotating the bar, the pressure of the rake wheels on the ground can be varied to the extent of lifting the wheels clear of the ground if required. Specifications 830,374, 830,375 and 830,376 are referred to.
