Abstract: 812,884. Extrusion machines. IMPROVED MACHINERY Inc. Dec. 13, 1957 [Dec. 31, 1956], No. 38824/57. Class 87(2). [Also in Group XXVI] A screw press having intermeshing screws mounted in a casing between an inlet and an outlet has the screw-threaded members mounted for rotation in the same direction about skew axes 24, 26 the threads of each member being of the same hand and for at least one turn the crest of one thread 23 is deeply engaged in the trough of the other thread 25 or threads to provide fluid sealing. The members may have a generally cylindrical form or be conical as in Figs. 23, 24. For each member the pitch diameter surface PD, Fig. 2, lies on a hyperboloid and is obtained by rotating a work piece W, Fig. 18, on a lathe while cutting the thread along a line T by a tool skewed to the axis of the piece W at an angle ¢α, where α is the skew angle between the axes 24, 26, Fig. 1: The pump shown in Fig. 23 may be used for pumping liquid-solid mixtures, such as wool pulp, and has meshing screw members, 42, 44 in a housing 50 having an inlet 51 and an outlet 53. The members 42, 44 have input extension shafts 54, preferably with a screw conveyer 60 thereon, mounted in bearings 55 and provided with seals 56. Output extension shafts 62 extend through bearings 64 at the opposite end of the housing and are provided with seals 66 and a thrust bearing 68. Each shaft 62 is geared to a common driving pinion 67 through a universal joint 621 and a gear wheel 622. Preferably the conical screws 42, 44 are so mounted that the pumping space increases towards the outlet. The thrust balancing means includes a collar 70 on the shaft 62, which collar extends through the stuffing box 66 and is intended to counteract the thrust on the annular area of the screwthread due to the discharge pressure. To compensate for wear, the members 42, 44 may be adjusted axially relatively to the housing 50 be replacing shims 72 by shims of greater thickness. By mounting conical screw-threaded members 42, 44 with their smaller ends adjacent the outlet from the casing, the arrangement may be used as a press, Fig. 24, to force liquid out of a liquid-solid mixture. The housing 80 is provided with an inlet 82 and an outlet 84, and surrounding the screws has small apertures 81 for the escape of liquid. The screws are carried by shafts 86 mounted in bearings 87, 88 and driven as in Fig. 23.

Abstract: 840,918. Mixing gases. UNION CARBIDE CORPORATION. Dec. 16, 1958 [Dec. 30, 1957], No. 40597/58. Class 86 A system for supplying gases for admixture in controlled proportions, particularly for supplying and mixing small quantities of gases, comprises pressure regulators 10, 11 supplied with the separate gases, e.g., argon and helium, at 21, 22, a common actuating-means 12 for the regulators which is so adjusted that the pressures of the gases immediately prior to admission to metering-devices 13, 14 are identical, a flow-meter 19 in one of the gas lines, and a combined outlet system for the gas mixture including a valve 18. The metering-devices 13, 14 each consist of a small bore tube 73, e.g., a length of hypodermic tubing, into which is inserted a length of smooth mandrel 74, e.g., piano wire, the gas flow with a specific pressure drop along the tube being determined by surface friction. The metering-effect is regulated by varying the extent of insertion of the mandrel into the tube, and is pre-set to give the required flow. The wire is held in the pre-set position by the seal 76 and the exposed end of the wire is protected by a press-button 95. The gas is admitted at 87 and leaves for admixture with the outflow from the other metering- device through the branch 83. For small gas flows, tubing with an inside diameter of 0.020 inches and a wire with a diameter of 0.015 inches are satisfactory. A differential pressure gauge 16 is connected with the gas lines immediately upstream of the metering-devices 13, 14 and any difference in the two pressures applied to the devices 13, 14 is corrected by turning the means 12 which increases the throttling action of one of the regulators 10, 11 and lessens that of the other. The flow-meter 19 is in one only of the supply lines, but since the combined flow is a known function of each single flow, the meter is calibrated to give the combined flow. The whole apparatus may be portable, being mounted in a box, the means 12 projecting through a slot in the box for manipulation and the gauge being readable without opening the box which has a hinged lid and flexible pipe connections to permit the opening when necessary.

Abstract: 1285251 Grinding J SUNNEN 24 Aug 1970 [4 Sept 1969] 40689/70 Heading B3D Apparatus for correcting imperfections in the surface 25 of a cylindrical workpiece being honed to a cylindrical shape on a honing machine including a mandrel 22 having workpiece engaging portions thereon, means 42 for rotating the mandrel, and means for generating a pattern of reciprocating motion between the mandrel and the surface being honed, the apparatus comprising means for determining the presence of variations from a true cylindrical shape of the workpiece, and means for shifting the position of the pattern of reciprocating motion relative between the surface and mandrel in a direction to remove the variation. The reciprocating motion may be imparted to the workpiece or mandrel and the pattern of the reciprocating motion may be shifted by manual or automatic means. In one embodiment, Fig. 1, the mandrel 22 is rotated by a belt-drive 44 from a motor 42 and the workpiece 24 is carried by an assembly 26 reciprocatable by a crank arm 32 driven by a motor 36 in a frame 56. An ammeter 45 is connected in the circuit of the motor 42 rotating the mandrel and if the bore of the workpiece is tapered so as to have a reduced diameter at one end, the extra load on the motor shows on the ammeter and an operator can rotate a handle 54 of a screw 55 engaging a nut 58 on the motor frame to shift the motor, and hence the pattern of reciprocating motion towards the smaller end of the bore so that that end receives more abrading than the other. In another embodiment, the shifting of the pattern of reciprocating movement is effected automatically by an integrator responsive to the load on the motor. In a further embodiment, a lever extends between a connecting rod connected to the crank and a rod connected to the workpiece support. The fulcrum of the lever is adjustable to determine the length of stroke, and the position of the patterns of reciprocating movement is varied by adjustment of the length of one of the rods. The means sensing the load on the motor for automatic control of the shifting of the pattern of reciprocating movement may consist of sensing the power factor or change of phase angle of the motor, belt tension or a pair of thermistors may be incorporated in a circuit which are responsive to the current in the motor for equal but different parts of the stroke of the movement and control a motor for shifting the pattern of the reciprocating movement.
