Arc-lamp electrodes.- A positive electrode for a projection lamp comprises a small core 3 impregnated with flaming materials surrounded by a. carbon shell 2 of at least four times but preferablv less than six times the diameter of the core. The total diameter of the electrode is about twice that of an ordinary name arc electrode and about the same as that of a pure carbon electrode for the same current density. The core may contain 50 per cent of mineral such as ceria. The negative electrode 4 is of smaller diameter than the positive and may be of pure carbon or may have a core 5 preferably harder than the shell but not mineralized. As shown, the negative electrode is arranged at an angle of 55‹ to the horizontal positive electrode. For a current of about 75 ampÞres the positive electrode is 5/8 inch in diameter, the arc length being 1/4 inch, and the potential drop 40-45 volts. The flame 13 sweeps vertically past the positive crater without enveloping the tip 14. The positive electrode is preferably rotated. In a modification, the electrodes are aligned and inclined slightly to the vertical; in this form the positive electrode is not rotated in order to produce an oblique crater parallel to the lenses of a projection apparatus.

Crops, in particular root crops, are lifted from storage clamps &c. by two sets of tines 5 extending through a plurality of discharge guides 8 and rotatably driven from an initial position to extend horizontally beneath the crops and then to lift the same for discharge to an endless scraper elevator. The tines are pivotally attached to a frame 4 rotatably mounted in a body 1 and each has support roller 6 and a further roller 39. From the initial position shown, in which the roller 6 is in engagement with a sprung guide 44, the roller 39, on rotation of the frame 4, abuts a stationary cam 23 whereby to force the tines 5 underneath the crops. The roller 6 simultaneously engages a curved guide 45. As the frame continues to rotate the tines firstly penetrate further beneath the crop, as the roller 6 passes over section 50 of the guide 45 and secondly lift the crops as the said roller 6 passes over section 51 of the guide 45. An abutment 40 adjacent the uppermost position of the tines, stops the movement of the tines, which thereby discharge their load on to a rearwardly sloping portion of the guides 8, and forces the roller 6 into engagement with a spring-mounted horseshoe shaped reversing member 7. The continued rotation of the frame 4 in combination with the reversing member 7 reverses the direction of the tines and withdraws them within the guides 8 and thus to their initial position.
