A cradle 26 is adjustable vertically on the frame members 1 by manual rotation of a shaft 27 carrying pinions 28 meshing with racks and may be locked in any desired position by clamps 31. A loading platen 42 is suspended by links 39 from a transverse shaft 40 passing through arms 37 pivoted to the cradle and has an extension 44. supporting weights 46. The platen is centralized by springs 45 and the extension 44 is formed with a clearance slot 45 for the shaft 40. The apparatus is intended to simulate the loads to which a filled container is subjected during transport by road or rail in a stack. The container is placed on the platform 8 and the cradle 26 is lowered until the platen 42 rests on the top of the container. The weights 46 may be adjusted to simulate conditions in stacks of various heights, and by adjustment of the cranks and variation of the speed of the motor the container may be subjected to vertical and/ or horizontal oscillations of any desired amplitude and frequency. The two crank assemblies may be driven by separate motors.

Title: Electromechanical delay device
IPC: H03H9/36
Filed: 1960-01-29
Abstract: 892,459. Electro-mechanical delay lines. STANDARD TELEPHONE & CABLES Ltd. Jan. 29, 1960 [Feb. 4, 1959], No. 3278/60. Class 40(8). A torsional stress is generated in a magnetostrictive delay line 2, Fig. 1, by means of a transducer which produces longitudinal and circumferential magnetic fields in the line. The circumferential field is generated by a toroidal coil 8 to which the signal pulses are applied. To prevent generation of longitudinal stresses the turns of the coil 8 are made as nearly parallel as possible to the axis of the line. Longitudinal magnetic bias is provided by a permanent magnet 3 and circumferential bias by a D.C. voltage source applied to the coil 8 or to the ends of the line 2. The output transducer 11 is similar to the input transducer but dispenses with longitudinal magnetic bias. Terminations 14, 15 are provided to prevent reflections. Fig. 3 shows in cross-section a helically wound delay line 21 of adjustable effective length using input and output transducers 22, 23 of the type of Fig. 1. The line 21 is in the form of a flexible thin-walled nickel tube, a single wire, or a bundle of fine wires encased in a thermoplastic tube or in a tube of polytetrafluorethylene. This may be encased in turn in a copper tube which is slit longitudinally. The line is coiled around a cage comprising two circular aluminium end members (not shown) joined by two groups of metal rods, 41 and 40. The rods 41 engage the inner side of the helix and are rotatably mounted in the ends of the cage whereby the whole cage may be rotated within the helix about a fixed shaft 31. In order to prevent slipping between the line 21 and the rotatable rods 41, the latter are arranged to ride -upon a fixed rubber ring (not shown) of the same internal diameter as the helix. The transducer 23 is mounted upon a support 46 which rotates with the cage around shaft 31. The shaft is provided with a helical groove of the same pitch as the helical line 21, the groove being followed by a pin 48 fixed to the support 46. Thus the coil of transducer 23 follows the helical line as the cage is rotated. Rollers 53 carried on the support 46 guide the delay line through the centre of the coil.

A rotational moulding machine carries one or more traversing drive units each with at least one laterally projecting arm carrying a rotatable mould platen, the traversing drive units carrying the mould platen from an oven to a cooling station and back. The traversing drive units 5 run on rails 8 between ovens 2 and 2A and cooling stations 3 and 3A. Projecting arms 10, 11 are rotatably mounted in bearings 9 on drive units 5 and crank arm 12, and the associated arms support the rotatable platen 16, which is driven from sprocket 19 by bevel gears 19, rod 14 and sprockets 17. The hollow mould which is sealed is mounted on platen 16 and can be rotated about the axis of rods 10, 11 and about an axis perpendicular to the platen 16. Plastics material in powder form is placed in the moulds which are then sealed while the traversing unit 5 is at a cooling station 3 and 3A. The moulds are set in rotation about both axes and both moulds on one traversing unit are moved into the oven, doors 4, 4A which keep the heat in the oven being opened. After the plastic has melted and spread over the inside of the mould, the mould assembly is moved by unit 5 back to the cooling area where the plastics article, after cooling is removed. The traversing units are controlled so that when one is in the oven, the other is in the cooling area.
