| 4600105 | Method and apparatus for sorting objects of ore by monitoring reflected radiation A method of ore sorting includes distinguishing ore objects or ore containing objects by the light reflected from a laser beam arranged to scan across each of the objects to be sorted. Where the surface of the object is transmitting to the light a halo is... | 07/15/1986 |
| 4451812 | Electrostatic shield An electrostatic shield for an electrical conductor element comprises a sheet-like array of closely spaced elongate electrical conductors interconnected at one end of the array by an end conductor for connection to a common or ground potential. The conduc... | 05/29/1984 |
| 4373638 | Sorting apparatus Apparatus for sorting ore rocks in which rocks are fed in stream past detector to measure characteristic selected as basis for sorting and into free flight trajectory from which selected individual rocks are deflected according to measure of said characte... | 02/15/1983 |
| 4365717 | Feed apparatus and method Feed apparatus and method for feeding objects such as ore rocks in such a way that they are arranged into at least one moving stream of spaced apart objects. The objects are fed onto a first conveyor belt which may have longitudinal channels to arrange th... | 12/28/1982 |
| 4320841 | Detection and sorting systems Method and apparatus for sorting objects according to the degree to which they possess a required characteristic. Objects are moved in a line on a conveyor belt past a line of detectors each responsive to the required characteristic. Each detector produce... | 03/23/1982 |
| 4231478 | Bulk sorting of particulate material Method and apparatus for bulk sorting particulate material such as ore rocks. A conveyor belt carries the material in a continuous stream past a detector responsive to a required characteristic to produce a time sequence of detector signals dependent on d... | 11/04/1980 |
| 4225089 | Fluid flow manifold A fluid flow manifold to deliver pressurized fluid to a series of outlets from a common supply duct has a block body and fluid outlets disposed in linear array along one side of the block. Valves are spread over an opposing side of the body block and conn... | 09/30/1980 |
