Abstract: Poultry conveying apparatus is used in gas stunning apparatus for the gas stunning of poultry. The conveying apparatus comprises a conveyor for transporting poultry through a gas or gases in a chamber of the gas stunning apparatus. The gas or gases are effective to stun the poultry. As the poultry is conveyed through the chamber poultry restraining elements engage the poultry to prevent or inhibit movement of the birds relative to the conveyor. This restrains the birds as they react to the gas or gases in the chamber and can thus prevent or reduce damage to the birds, and can ensure that there is little or no movement of the birds relative to the conveyor.

Abstract: A detection system for detecting X-ray radiation from a sample located in a microbeam instrument. The detection system comprises: a. a pulse tube cooler; b. a compressor connected to the pulse tube cooler; c. a sensor coupled to the pulse tube cooler; and, d. a housing containing the pulse tube cooler and the sensor. The pulse tube cooler, the sensor and at least part of the housing are sufficiently small to be positioned inside the microbeam instrument in use, thereby allowing the X-ray radiation from the sample to be detected by the sensor.
