摘要： A hydroextractor in which a liquid material to be processed can be introduced into a hydroextracting chamber under a small pressure and the chamber can be filled with the material in a short period of time to thereby improve the operational efficiency, and a cake of the hydroextracted material can be easily removed from the hydroextracting chamber. For these purposes, this hydroextractor is arranged such that upper and lower filter cloths 4, 9 are provided at the top and the bottom of the hydroextracting chamber 27 extending substantially horizontally, and that a diaphragm 8 shaped like an inverted dish is disposed on the upper surface of the upper filter cloth 9. Further, a pressure chamber 32 is provided on the upper side of the diaphragm 8. The hydroextracting operation is performed by filling the liquid material in the hydroextracting chamber 27 and generating a pressure in the pressure chamber so as to press the diaphragm 8 downwardly.

摘要： A filtration/separation apparatus in which a filter cloth is arranged to travel and face a rotor so that a partitioned space chamber defined by the cloth and rotor is gradually narrowed in accordance with the rotation of the rotor. The space chamber defined is partitioned by vanes provided on the rotor, so that the positional relations in contact between the tip ends of the vanes and the filter cloth are maintained desirable with a high accuracy.

摘要： A vortex blower includes an induction motor (1) and a blower portion (2) driven by the motor. The blower portion comprises an impeller (4) and a casing (8). The impeller is so mounted on a rotary output shaft (3) of the induction motor that the impeller is disposed near the induction motor. The casing is so disposed that the impeller is interposed between the induction motor and the casing. An inlet port (10) and an outlet port (11) are provided on an end of the casing opposite to the induction motor. The blower portion has approximately the same diameter as that of the induction motor.

摘要： A rolling mill for rolling metal strip (11) moving in a horizontal rolling direction, has work rolls (1) which engage the strip and are supported vertically by backup rolls (2) through which drive is applied. The work rolls (1) are supported in the horizontal rolling direction by support rollers (4) contacting them at locations confined to intermediate regions between the work regions and bearings (8). The work rolls are shiftable in the horizontal rolling direction. To provide control of the horizontal forces during rolling, there are position control means (5,7) for the support rollers operable to move and locate the support rollers so as to shift the work rolls (1) to a predetermined location at which the vertical axial plane of the work rolls (1) is offset in the horizontal rolling direction from the vertical axial plane of the backup rolls (2). The support rollers (4) maintain the work rolls at the predetermined location during rolling.

摘要： This invention provides a working roll shift type rolling mill which-comprises a housing including upper and lower working rolls having working roll chocks at their respective end portions and upper and lower reinforcing rolls having reinforcing roll chocks at their respective end portions for supporting the working rolls. The rolling mill further includes shift devices disposed to allow the upper and lower working rolls to shift relative to each other in the direction of their respective axes and hydraulic cylinder means disposed to apply a vertical force to the vertically facing portions of the respective upper and lower roll chocks at the opposite end portions of the upper and lower working rolls. The upper and lower roll chocks are combined with the respective working roll chocks so that they can be moved along their axes together with the upper and lower working rolls, the hydraulic cylinder means respectively including hydraulic rams disposed so that one end of the respective hydraulic rams may be brought into contact with the horizontal wall surfaces of the upper and lower working roll chocks disposed vertically adjacent to each other, the respective working roll chocks of the upper and lower working rolls and the reinforcing roll chocks of the respective upper and lower reinforcing rolls having side surfaces formed in a flat shape, and the housing of the rolling mill further including windows each having a side wall formed in such a flat shape that the upper and lower working roll chocks and the upper and lower reinforcing roll chocks may be lifted and lowered. According to the rolling mill having the above-described arrangement, the upper and lower working rolls in a quadruple rolling mill are capable of being shifted relative to each other along their axes, thereby enabling not only improvements in the accuracy of thickness control of rolled material in the widthwise direction and the performance of schedule free rolling but also easy change of the reinforcing rolls.
