Abstract: 1,226,428. Control of A.G. motors. INDUSTRIE A. ZANUSSI S.p.A. 5 June, 1968 [9 June, 1962], No. 26839/68. Heading H2J. The stator windings 6, 7, 8 of an induction motor are energized sequentially for periods equal to one or more complete half cycles of a single phase A.C. supply which is rectified (but unsmoothed) at 1. The windings are switched one at a time by thyristors 10, 11, 12 controlled by a device 13 which includes a frequency divider; by altering the dividing factor of this the speed of the motor is changed in steps. Device 13 also has pulse shaping circuits and means for determining the sequence and hence the direction of rotation of the motor, but is not disclosed in detail. The motor may have a squirrel cage or a wound rotor.

In a blow-moulding process in which a tubular blank is continuously extruded, successive portions thereof are fed to successive blowing moulds moving relatively thereto, severed in the respective moulds and one end of each blank is clamped within a mould before the other which is then engaged when the centre line of the other end coincides with the centre line of the mould. Extrusion is preferably effected vertically downwardly, the severing being effected simultaneously with or after at least one of the clamping steps. In one embodiment, the lower end is clamped first so that the blank is inclined relative to succeeding portions of the blank when the other, upper end is engaged the inclination depending on the speed of the relative movement and the length and diameter of the blank. The mould (Fig. 2, not shown) may be inclined during clamping and thereafter pivoted so that the blank is vertical. In another embodiment (Figs. 3, 4, not shown), the upper end may be clamped first, so that the blank may assume a vertical position by gravity before the lower end is clamped. The mould may have separately movable upper and lower mould parts (Fig. 3, not shown) to clamp respective ends of the blank or (as in Fig. 4, not shown) the upper mould parts may be spring-urged together.

Abstract: 1,251,310. Controlling reactors. ROYAL INDUSTRIES Inc. 11 May, 1970 [16 June, 1969], No. 22604/70. Heading G6C. [Also in Division H2] A drive mechanism for a "part length" control rod, i.e. a control rod in which only a portion contains neutron absorber, includes drive means for linearly positioning the control rod in a reactor core for positioning the absorber portion in selected locations in the core, and means for holding the position of the control rod upon de-actuation of the drive means, e.g in the event power is lost or interrupted to the drive means. This restraining action causes the control rod to stay put or fail safe rather than to fall in as a result of the "scramming" fail safe action of the more conventional control rods. The drive means includes a motor having a stator for generating a rotating magnetic field and a rotor coupled to be responsive to the magnetic field for rotation therewith. The rotor assembly carries roller-nut means cooperating with a lead screw for controllably positioning the control rod, and brake means for restraining the lead screw when the stator is de-energized, thereby providing fail safe holding of the position of the control rod. The rotor assembly comprises pivoted segments which are swingable in opposite directions in response to energization and de-energization of the stator and which carry the brake means.

A conveyer for transporting cylindricalshaped ferromagnetic articles, comprises a pair of parallel endless chains 1, 1<SP>1</SP>, between which extend a plurality of cross-bars 3 at least every other of the cross-bars being magnetized. The cross-bars are so spaced that the distance between adjacent bars is less than the diameter of the articles 4 to be transported. As shown, the articles are cans having beaded ends. At a change of direction of the conveyer, the chains 1, 1<SP>1</SP> pass over a sprocket 8 having radial projections 9 which are magnetic. The cans are discharged (Fig. 12) by being dislodged by non- magnetic arms 26 of a return sprocket. The sprocket 26 may however be disposed adjacent a straight run of the chain (Fig. 8, not shown). In another arrangement (Fig. 14, not shown) a discharge sprocket (28) has arms which are magnetized more strongly than are the bars 3. The cans are thus drawn off on to the sprocket (28) and are prised off the latter by the action of a shoot (30).
