An arrangement for cooling the gun barrel of a combat tank wherein the gun barrel is provided with helical cooling channels on its outer surface, and an insulation layer on at least the inner circumferential surfaces of the cooling channels. This reduces the IR signature of the gun barrel during combat and avoids deformation of the barrel under the influence of radiation from the sun.

In an exemplary embodiment a head with an installed television camera is present which head is connected in a plug-in fashion to a mobile tube section. The control of the orientation of the head during video exploration is effected by a system of hydraulic fluid encased Bowden cables which can transmit not only mechanical forces but also electric energizing and signal currents and which permit a conducting away of dissipated heat. The transition from the tube section to the head is sealed off by means of drawover seal.

A process and apparatus are disclosed for the automatic examination of eggs for cracks or fractured surface areas in their shells. The process includes the steps of directing light from at least one light source onto the egg, and detecting and measuring the intensity of the light emanating from the egg. Cracks or fractured surface areas in the egg shell will allow a greater intensity of light to emanate from the egg. Such relatively higher intensity is measured to determine if a crack or fracture exists. The apparatus consists of at least one light source, a device for rotating the egg, apparatus for moving the light beam over the surface of the egg shell, and a device for detecting the intensity level of the light emanating from the egg.
