Apparatus for making wire spirals having straight extremities extending substantially in alignment with each other comprises a rotating winding head, a wire guide member and a mandrel on which the wire is wound and which can be retracted on completion of the winding and is characterized in that the wire guide member is swingably mounted with respect to the mandrel in such a way that during winding the wire is fed to the mandrel through the mouthpiece of the wire guide member at an angle to the axis of the mandrel substantially equal to, or slightly less than, the angle of the winding pitch. Wire 6, clamped at one end in a channel 2 in a winding head 1, is guided to a mandrel 4, on which it is wound by rotation of the head 1, by a guide 5 inclined relative to the mandrel 4 so that its guide channel 5<1> is at, or slightly less than, the pitch angle. The guide 5 is carried by a slide 10 moved along the mandrel 4 during winding by a wedge 15 moved by electromagnetic means acting against a brake and engaging a roller 22 on the slide 10. Just after the requisite number of turns has been wound the winding head 1 is stopped and rotated back a little, slightly to expand the coil, being correctly positioned by the engagement of a recess in a cam 31 on the head engaging a roller. The guide 5 is then swung around a pivot on the slide 10 past a position in alignment with the wire in the head 1, to overbend the wire about a guidepin 8 on the guide 5, and then back into alignment with the head 1. The guide 5 is then again moved axially of the mandrel 4, this time by a wedge 15<1>, moved by electromagnet means and engaging a roller 23 on the slide 10, to form a straight end portion of the wire. The wire is unclamped from the head 1 and clamped by the guide 5 while the guide 5 continues to move. The mandrel 4 is retracted axially and the finished coil is cut off by cutters 12. Specification 218,674 is referred to.

Abstract: 392,995. Centrifugal separators. KNOWLES, J. R. and CARTER, B. C., 24, Essex Street, Strand, London. Dec. 18, 1931, No. 35128. [Class 23.] A centrifugal machine for the separation of liquids such as oil and water, has a rotary drum which is divided by longitudinal vanes into a number of narrow channels for the passage of the liquids. The cross sections of the vanes are radial near the axis of the drum, and inclined near the periphery. The drum has two parts 10, 11 supported in bearings 8, 9 which yield slightly under radial pressure. The outer casing has two parts 5, 6 held together by a ring 7 engaging bevelled edges, and supported on a base chamber 2 having an inlet 1 and a filter 3. Glands are provided between the fixed and moving parts and any liquid which leaks past the glands is returned to the sump. At the lower end of the drum, where the liquid entry is arranged, vanes 42 are placed immediately below a number of narrow tubular channels. These are formed by building up a block of square or half-hexagonal tubes, or by a system of plain and corrugated rings. Above these tubes 27 the drum is divided by inner radial vanes 28 held in slots in the hollow shaft 29 by locking rings 30, and also by inclined vanes 32 held in slots in the ring 33 in the drum. The intermediate edges of the vanes 32, 28 are held by rings 31. A domed metal sheet 34 forms a top plate and makes .with the casing a passage, with vanes 36, for the flow of the separated water. The liquid mixture passes the inlet 1 and filter 3, and is rotated by vanes 12 on the inlet sleeve 13, and vanes 42 on the drum. It then passes through the tubes 27, and between the vanes 28, 32. The separated water passes behind the plate 34 to its discharge outlet and valve 25. The separated oil passes through apertures 35 to the hollow central tube 20 from which it is discharged through upper and lower nozzles 18, 19 to the passages 23, 22 and the valve 24. The purity of the separated liquids can be varied by adjusting the valves 24, 25 to vary the rate of discharge. The flow of the separated oil may be controlled by means of two floats 43 which move radially on arms 44 in accordance with the position of the dividing surface between the liquids. The movement of the floats causes the rotation of a ported sleeve 45 to vary the effective area of the apertures 35. A skimming lip may be provided in the passage leading to the water outlet, and the liquid skimmed off is returned to the sump through the channel 59 for further treatment. A thrust bearing is arranged inside the shell 37..
