Inventor: ROUSU PASI PETTERI
IPC: C05D1/00
Filed: 1999-04-06
Abstract: The invention relates to a process for producing cellulose and a fertilizer by-product by using a closed cycle of cooking chemicals and process waters. In the process of the invention, the pulp is bleached by at least partly using potassium hydroxide as a bleaching chemical. Thus, a bleach concentrate rich in potassium is obtained from the bleach filtrate, which bleach concentrate is combined with ashes obtained from the burning of lignin and other organic matter recovered from pulp production as a by-product, in order to be used as a potash fertilizer. The bleach-concentrate can also be used as a potash fertilizer as such. The invention also relates to a potash fertilizer obtained this way.

Title: Engine starter
IPC: F02N15/02
Filed: 1950-01-16
Abstract: 671,128. Turning-gear. BENDIX AVIATION CORPORATION. Jan. 16, 1950 [Feb. 25, 1949], No. 1090/50. Class 7(v) In an engine starter comprising an engine engaging or jaw member 20 connected to a rotatable driving barrel 38 by a friction clutch 44, an axially stationary rotatable nut 40 and a screw shaft 32 adapted to be moved by the nut 40 longitudinally to move member 20 into engagement with a cooperating engine member 22 and rotatably to crank it, there is provided means such as flanges 34 and 56 and springs 52 associated with the screw-shaft 32 for varying the setting of the clutch in accordance with the axial position of the screw-shaft 32 relative to the nut 40; the flanges 34 and 56 may cooperate to apply a gradually increasing pressure to the friction clutch when the screw-shaft moves from its retracted position to one of full engagement with engine member 22. The jaw member 20, which has a shank with two external diameters 24 and 26 joined by a ramp 28 so that in the inoperative position a split ring 14 of phosphor bronze or like material engages the larger shank diameter 24 whilst an oil seal 12 engages the smaller shank diameter part 26, is splined to the screw-shaft 32, the latter having the flanges 34 located near the wall 36 of the barrel 38. The nut 40 is threaded to the screw-shaft 32 whilst the friction clutch 44 connects the barrel 38 and nut 40. A number of the springs 52 are circumferentially spaced and confined between an annular member 54 and a backing plate for the clutch plates. In opera-. tion, the starter motor drives the barrel 38 through planetary gearing 66 and the force exerted by springs 52 gives the clutch sufficient torque capacity to rotate the nut 40 and so urge screw-shaft 32 leftwardly, the screw-shaft and jaw member 20 being prevented from rotating by the ring 14 acting on the larger shank diameter 24. When jaw members 20 and 22 engage, flange 34 abuts the flange 56 on annular member 54 whereupon further leftward movement of the screw-shaft will cause a corresponding movement of member 54 thereby increasing the torque capacity of the clutch, until the jaw members are fully meshed and flange 56 abuts nut 40 when cranking commences. In the meantime split ring 14 has moved down ramp 28 so as to permit free rotation of jaw member 20.

Title: Improvements in power-operated brakes particularly for winding and haulage engines
IPC: B66D5/26
Filed: 1955-01-17
Abstract: 764,214. Winding engine brakes. BARCLAY SONS & CO., A., BELL, R. W., and ELLIS, R. Jan. 17, 1955, No. 1328/55. Addition to 697,401. Class 103 (1). In a power-operated brake, particularly for winding engines, of the kind described in the parent Specification, an additional fluid pressure cylinder 3, 4 is added whereby the force applied to engage the brake shoes on the drum by the spring 8 is implemented by fluid pressure acting on the left-hand side of piston 4, which through crosshead 5, rods 6 and member 7 further compresses the spring 8. Thus, if during normal operation, pressure is always present in the cylinder 3, and when during operation the force of the pressure in cylinder 3 acting in combination with that of the spring 8 itself is balanced against the force of pressure acting against piston 2, a reduced braking effort can be obtained by the simultaneous reduction of pressure in both cylinders 1 and 3. In another embodiment the auxiliary cylinder and piston 3 are secured to the opposite brake post.
