Abstract: 1,239,581. Retractive switches. JOSEPH LUCAS (INDUSTRIES) Ltd. 17 Dec., 1968 [12 Jan., 1968], No. 1832/68. Heading H1N. A switch comprises two body parts 16 and 11 respectively carrying a moving contact 19 and a fixed contact blade 15. The part 16 is of conductive material and has a portion 17 which is an interference fit within the part 11, moulded of synthetic resin. During manufacture the required contact gap is readily set by holding the plunger 18 depressed against the action of spring 21 by the amount it will be depressed when in use, and then forcing the body part 11 towards the part 16 until a test circuit between terminal 14 and the part 16 is established; the plunger 18 is then released, leaving the desired gap between contacts 19 and 15. The interference fit is such that no other locating or securing means is required.

In a hydrocyclone for treating cellulose fibre slurry, the amount of liquid discharged with a heavy reject fraction is controlled by means of a device comprising a cylindrical vortex chamber 1 connected to. the bottom outlet of the hydrocyclone and provided with a fixed outlet port 4 located in or close to the cylindrical wall of the chamber 1, and a flow guiding member 7, Fig. 1, adjustably positioned within the chamber for deflecting the vortex flow, produced in the chamber by a portion of the liquid discharged therein with the reject fraction, away from the cylindrical wall of the chamber at the location of the outlet port 4, the extent of the deflection, and hence the amount of liquid discharged through the outlet port 4, being determined by the position of the flow guiding member. As shown in Figs. 1 and 3, the upper side of the member 7 facing the interior of the vortex chamber 1 has semi-circular surfaces 10, 11 respectively perpendicular and inclined relative to the axis of the chamber, the two surfaces being joined by a triangular surface 12 parallel to the axis and extending diametrically through the chamber. The member 7 is rotatable by means of a pivot shaft 8 and a handle 9. In Figs. 4 and 5, the outlet port 4 is located in the bottom of the chamber 1. The guiding member includes a body 13 extending along a portion of the cylindrical wall of the chamber I and having a substantially uniform radial breadth and an. axial height which increases continuously from the bottom of the chamber in the direction of the vortex flow 6. The body 13 is rotatable by means of a pivot pin 17. In a modification, Figs. 6 and 7 (not shown), the flow deflecting body (19) has a uniform axial height approximately equal to that of the chamber and a radial breadth which increases in the direction of the vortex flow, the outlet 4 in that case being in the cylindrical wall of the chamber. In Fig. 8, the flow is deflected by means of a plate spring 23 having a fixed end 23<SP>1</SP> and an opposite end 23<SP>11</SP> adjustably positioned by means of a screw 24. The width of the spring substantially corresponds to the axial height of the chamber 1.

Abstract: 1,257,367. Gear pumps and motors. ROBERT BOSCH G.m.b.H. April 11, 1969 [April 13, 1968; Oct. 10, 1968], No. 18619/69. Heading F1F. A seal 25 divides each of gaps 16, 17 into pressure-loading zones 27 .... 32 for bearing bushes 11, 14 or 12, 13 supporting gear-wheels 8, 9. Fingers 26 on the seal extend beyond the periphery of bores 2', 2" for the gear-wheels. Passages 35, 36 connect the zones 30, 27 to the low-pressure and high-pressure sides, respectively, the other zones and the extremities of the zone 27 being in communication with the gear tooth spaces through grooves 34. This arrangement together with spaces 37 due to fluid-pressure on the bushes results in substantial matching of the pressures in said zones and the gear-tooth spaces. The spaces 37, grooves 34 and zones 28, 29, 31, 32 effect a gradual pressure build-up in the gear-tooth spaces and thus reduce noise. Extrusion of the seal is prevented by a strip 33. Another embodiment, Figs. 7 and 8 (not shown), differs largely in that the seal lies in grooves on the bearing bushes. The spaces 37 may be established by projections on the bushes or the housing or may be replaced by recesses in the housing.

Abstract: 1308422 Programmed control of machine tools WERKZEUGMASCHINENKOMBINAT "FRITZ HECKERT" KARL-MARX-STADT VEB 5 May 1971 13224/71 Heading G3N [Also in Division B3] The operation of a numerically-controlled lathe is modified, in dependence on the load on the cutting tool, by reduction of the cutting depth to keep the load within pre-set limits and withdrawal of the tool when the load falls below the lower limit, or a programmed end point is reached. As shown, a tool 1 is located at a point A in accordance with instructions from a data carrier of the numerical control system. A programmed movement from a point PO is made and a cut commenced on the workpiece at B. Due to the oversize contour 2 of the workpiece the tool load causes the cut path to deviate at 12.2 and the point at which the deviation commenced is stored in the numerical control system. The load falls over section 11. 3 to permit a straight line cut and ends when the load falls below the lower limit so that the numerical control system carries out a retraction 11.5 and a withdrawal 11.6 to the stored position at which the tool is returned along a path 11.7 to the programmed cut. The sequence is repeated until movement occurs along path 12.4, which is terminated at a programmed end position P, and subsequent sequenced movements proceed to a final cut 16.1. In a modification, where movement occurs over a circular path, the retraction and return movement are radial and the withdrawal movement is circumferential.

The outer cylinder 22 is arranged to slide within the casing 40 and the inner cylinder 24 within the outer cylinder 22, seals being preferably provided at the sliding interfaces. The casing 40 is closed at one end and open at the other and a pressure gas source (Fig. 1, not shown) communicates through a restriction 18 in the closed end of the casing to act on the adjacent ends of the coaxial cylinders 22, 24. A piston-like member 34 is rigidly attached to the closed end of the casing and has a piston portion adjacent the open end of the casing and in sliding sealed contact within the inner tube. The member 34 is provided with a radially extending outlet 32 which communicates with the pressure gas source through an axial passage 30 in the member 34. In operation pressurized gas passing through the restriction 18 drives the two cylinders 22, 24 along the casing together until the outer cylinder 22 is stopped with its inner end adjacent the open end of the casing. The stopping of the outer cylinder 22 substantially coincides with the opening of the radial extending outlet 32. Pressurized gas then passes through the outlet 32 to act on the inner cylinder 24 to eject the inner cylinder from the device. The initial pulse of pressurized gas through the orifice 18 is cushioned by a reservoir 28. The inner cylinder 24 is connected to the object to be ejected by a stud 26. Pressurized gas is produced by firing a cartridge, the gas also actuating an overcentre toggle mechanism for releasing the object to be ejected (Fig. 1, not shown).
