Title: Method for controlling screening and grinding plants
IPC: H02P29/40
Filed: 1967-10-24
Abstract: 1,148,358. Automatic control of grinding. POLYSIUS G.m.b.H. Oct. 24, 1967 [Jan. 11, 1967], No.48260/67. Heading G3R. [Also in Division B2] In a grinding plant, material, passed through coarse and fine grinding chambers, is screened and the grit returned for re-grinding to the two chambers in proportions which are varied automatically if the noise in the coarse grinding chamber is above or below predetermined limits, the rate of supply of fresh material also being automatically controlled by the noise in the coarse grinding chamber. As shown, a feeder 9 driven by a motor 10 supplies material to a grinder 1 having a coarse grinding chamber 2 and a fine grinding chamber 3, the ground material being transported by a bucket-conveyer 4 to screens 5 and 6 supplying finished material at 7. Grit is returned from screen 6 to the fine grinding chamber 3 while that from screen 5 is apportioned between the fine and coarse grinding chambers in dependence on the setting of a distribution valve operated by a motor 8. The rate of supply of ground material by conveyer 4 is maintained constant by comparing the power supplied to its driving motor 15, as measured at 16, with a reference value at 14 so that any difference is effective to alter at 11 the level of sound maintained constant in the coarse grinding chamber by a microphone 12 controlling the speed of feed motor 10. Deviations in the output of microphone 12 beyond predetermined limits determined by a dead band unit 18 are effective to adjust the position of the distribution valve controlled by motor 8 so as to prevent overloading or underloading of the coarse grinding chamber. Grit output instead of grinder output may control the sound level.

Abstract: 1,002,450. Web coating apparatus. CROWN ZELLERBACH CORPORATION. Dec. 31,1962, No. 49138/62. Heading D1L. [Also in Division B5] Apparatus for casting a coating on to a moving sheet to be coated is adapted to maintain a gaseous pressure on the trailing face of the coating different from that on the leading face, the pressure being applied to the trailing face by conveying the gas through a plurality of adjacent independent passageways of a chamber opening toward the trailing face at a slit of a nozzle adjacent to the moving sheet and immediately behind the coating nozzle. Generally atomospheric pressure is allowed to act on the leading face and a negative gaseous pressure is maintained on the trailing face, e.g. by the action of a suction fan. Apparatus as shown, adapted for casting a film 8 (Fig. 1) on a moving surface 3 is adapted to maintain a gaseous pressure on the trailing face of the film 11 (Fig. 2) different from that on the leading face 12, pressure being applied to the trailing face by conveying the gas through a plurality of adjacent independent passageways 24 (Fig. 3) of a chamber 9 opening toward the trailing face at slit 22 of nozzle 21 adjacent to the moving surface 3, and immediately behind the casting nozzle 4. Generally atmospheric pressure is allowed to act on the leading face and a negative gaseous pressure is maintained on the trailing face (e.g. by suction fan 19). Pressure in the respective passagewyas is selectively regulated by slide valve 28, 29 (Fig. 4) the total pressure being regulated by slide valve 32, 33 (Fig. 3). Thus the applied pressure may be equalized along the whole width of the slit 22. A barrier 23 extends the whole width of the slit between chamber 9 and moving surface 3, to prevent ingress of air. Regulation of the applied pressure as described enables very uniform thickness film to be obtained. Specification 741,818 is referred to.

A floor slab 10 cast about a plurality of the columns 11 is connected to each of the associated hoisting devices by a pair of screw-threaded lifting rods 16. Follow-up nuts 18, 19 are provided for conventional step-by-step lifting of the slab 10. The cross-bars 13, 14 have apertures 15 large enough to permit the passage of the rods 16 and any couplers 17 used for connecting two rods 16 in end-to-end relationship. The nuts 18, 19 are split or hinged and are carried in nut support members 20, 21 of tubular form which are formed internally with a recess 22 at each end to receive the nut 18 or 19 so as to prevent it opening and arranged so that rotation of the member 20, 21 rotates the nut 18, 19, respectively. When lifting has proceeded to the stage where a coupler 17 has passed into the interior of member 20 a further lifting stroke of the jack 12 is effected, but before the retraction stroke, and while the slab 10 is supported by nut 19 and member 21, member 20 and its nut 18 are rotated until the nut 18 has moved sufficiently far upwards for the member 20 to be lowered so as to disengage from the nut 18 which can then be disengaged from the rod 16. The member 20 can then again be raised and the nut 18 reengaged with the rod 16 below the coupler 17 and received in the lower recess 22 by lowering the member 20. In the embodiment shown in Fig. 3 a nut 24 of split or hinged construction has an integral extension 23, opening of the nut 24 in use being prevented by a collar or ring 25. A similar ring or collar may be used at the end of the extension 23. In use lifting proceeds until a coupler 26 passes into the interior of the extension 23. The collar 25 is then disengaged from the nut 24 so that the nut 24 can be disengaged from the lifting rod. The nut 24 is then. turned upside down so that it can be re-engaged under the coupler 26 whereupon lifting may proceed.

Abstract: 1,260,900. Rotary positive-displacement motors. CHARBONNAGES DE FRANCE. Oct. 15, 1969 [Oct. 15, 1968], No.50749/69. Heading F1F. A hydraulic motor producing a high torque has a housing 5 containing rotatable cylinders 2a, 2b circumjacent a rotary shaft 1 and comprising abutments 3a, 3b that co-operate with blades 4a, 4b, respectively, on the shaft. Walls 5a, 5b can be deflected by fluid-pressure in annular chambers C 3   a , C 3 b  to lock the cylinders. Conduits 10, 11, 20, 21 for hydraulic fluid are formed in the shaft, Figs. 1b and 1c (not shown), and communicate with chamber C 1 a , C 2 a , C 1 b , C 2   b  between the blades and the abutments. Hydraulically actuated valves HV1, HV2, HV3 connect the chambers to series connected pumps PP, PG or a tank D, these valves being controlled by a vane HVO, which is actuated by mechanism FC1 on each abutment when engaged by the respective blade. Pressure-limiting devices 18, 19, 26 and a non- return valve 27 are provided as shown. When the valves are set as shown the cylinder 2a is locked and the cylinder 2b is free to rotate with its abutment ahead of the blade 4b as the shaft undergoes angular displacement by the blade 4a, the angular velocity of the cylinder 2b being initially at least twice that of the shaft owing to the chamber C 2   b  being charged simultaneously by the pump PG and fluid transfered from the chamber C 2   a . The cylinder 2b revolves at the same velocity as the shaft when its abutment engages with the trailing side of the blade 4b. When the blade 4a approaches the abutment 3a the valve HVO is operated so that the settings of the valves HV1, HV2, HV3 are reversed. Rotation of the shaft thus continues while the cylinder 2b is locked and the cylinder 2a is released. The motor may have more than two cylinders. In another embodiment, Figs. 4 to 6e (not shown), the conduits 20, 21 are replaced by conduits connected to the conduits 11, 10, respectively, the device 26 and valve 27 are dispensed with, and the cylinders are connected to each other and the shaft by differential gears. The mode of operation is generally similar to that of the embodiment shown saving that the gears transmit torque from the unlocked cylinder to the shaft, the torque output being thereby increased.
