Filed: 1957-06-17
Abstract: 829,813. Ore samplers. MARCONA MINING CO. June 17, 1957 [June 27, 1956], No. 19074/57 Class 58. A machine for removing samples from a mass of material on a moving conveyer, 10, comprises a sampling car, means for supporting said car for travel in the direction of the conveyer, means for causing the car to travel at the same speed and in the same direction as the conveyer, and means carried by the car and driven transversely of the conveyer for removing samples whilst the car and conveyer are moving at the same speed. The car carries a shoot 67 and means preventing spillage of sample between conveyer and shoot, said means being a plate 66 provided with a lug 73 at each side. The plate 66 and shoot 67 can slide laterally, Figs. 5 and 6 (not shown) the plate 66 being urged into conveyer-engaging position by springs whilst sampling proceeds. When sampling has finished a roller 84 engages a cam and urges the plate away from the conveyer. A hopper 68 carried by the car receives the sample. The sample is removed from the conveyer by a scoop assembly 44 actuated by chains 54. The car straddles the belt and for sampling, the scoop assembly moves down to engage the ore on the conveyer. Should the scoop mechanism fail the ore will carry the scoop assembly with it but an incline on the rail track at a point beyond where normal sampling would have finished raises the car and thereby the scoop assembly out of engagement with the ore, thus preventing damage.

A method of making a radiation record comprises forming an electroconductive image by radiation on a layer of photoconductive zinc oxide in an insulating binder, passing a current through the layer and depositing electrolytically, in accordance with the current, a material which reduces the ability of the layer to store electric charges, applying an electrostatic charge to the dry surface in the absence of the radiation to which the surface is sensitive, applying xerographic toner to said charged surface and fixing the toner to the surface. The electrolyte may contain a silver salt or ferrous chloride tetrahydrate and dithiooximide in ethyl alcohol and may be applied with a metal backed brush serving as one of the electrodes, simultaneously with exposure of the layer to radiation. The toner may comprise a powder or a liquid: examples given are:- Amberol F-71 with carbon black; Graph-o-fax Toner Powders 1, 5; Reversal Toner No. 25. "Xerox" Copyflo Developers Types N-1 P-1 ("Xerox" is a Registered Trade Mark); aluminium silicate, and may be applied by the well-known cascade, magnetic, liquid development methods with a suitable potential difference between the powder supplier and image paring layer to produce a positive or negative image, as desired. The contrast of the image can be varied by choosing different dyes for the zinc oxide binder, different toners and by the density of material deposited electrolytically on the layer. The image may be fixed by fusion or the application of pressure. If the plate is to be used for lithographic printing with a greasy ink the toner must be more hydrophitic than the material deposited electrolytically or vice versa.
