摘要： An apparatus for sorting or otherwise treating objects, wherein the apparatus includes an endless belt which is in contact with a guide by means of which the endless belt is given a curved portion. At least one path between the guide and the curved portion of the belt is provided for the passage of objects therethrough. The path has an inlet portion arranged to receive objects which have traveled thereto along a trajectory which has a substantial horizontal component at the inlet portion, and the path has a vertically disposed outlet portion. A feeder is provided for feeding the objects to the inlet portion of the path. The belt is driven so that objects passing into the path through the inlet portion thereof are centrifugally forced against the belt and carried thereby to the respective outlet portions. The objects are sorted or otherwise treated as they fall under gravity from the outlet portion.

摘要： A valve device is disclosed for controlling the delivery of gas from a pressurised source suitable for use in a pneumatic ejector in particle sorting apparatus. It uses a diaphragm as a valve member disposed over an output port from a chamber which is in substantially continuous communication with a source of gas or air under pressure. Both sides of the diaphragm are exposed to pressurised gas or air in the chamber. For this reason, and because the diaphragm itself engages the output port to close it, when the input pressure is applied there is a differential pressure which elastically deforms the diaphragm to close the output port. The diaphragm has a piezoelectric element, and the valve device includes an electric circuit operable to selectively activate the piezoelectric element and withdraw the valve member from the output port to admit pressurised gas or air thereinto.
