The description is substantially identical with that of Specifications 1,013,805 and 1,013,806, but the claims relate to means for raising and lowering a loaded pallet and means for transferring at least the upper part of the load laterally of and from the pallet. A loaded pallet 16 is fed into an elevator shaft 12 by a conveyer 10, the elevator frame 11 being carried on a driven chain 18. The frame 11 is raised to bring the top layer of articles within clamp means (Fig. 4) which comprise movable abutments 20 linked and pivoted on to pistons and cylinders 23. The clamp means hold the top layer while the frame is lowered slightly and then they move along rails 27 to deposit the articles on a conveyer 28 from which they are discharged by conveyers 29, 30, 31 (see Specification 1,013,806). The raising and lowering of the loaded pallet continues until it is emptied when. it is discharged into the pallet magazine (see Specification 1,013,805).

In a pulse generator of the type described in Specification 1,053,656 the pulse amplitude is stabilized by a charging circuit substantially as shown. Thyratron V3 is triggered to allow the pulse forming network 5 to charge resonantly from the D.C. supply 1 via L1. When network 5 has charged to a predetermined voltage, thyratron V1 is triggered so that the charging current is diverted via D3 into capacitor C. Thyratron V2 is now triggered to discharge the network 5 into a transformer-coupled load R1. Capacitor C now discharges into the network 5 via L2, D2 and D4. The circuit D2, L2, C, D4 also removes reverse voltage from network 5 under fault conditions. V3 may be replaced by a diode.
