Abstract: A control system for thermo optical control of focus position of an energy beam in an additive manufacturing apparatus has a first doped medium and a second doped medium, each of which is optically transparent and doped with a dopant. The first doped medium has a positive thermo-optical coefficient (dn/dT) and the second doped medium has a negative thermo-optical coefficient (dn/dT) and is in series with the first doped medium. An energy beam input or coupling is configured to generate or receive an energy beam that is required to be controlled, the energy beam being within a first wavelength range and directed towards the first and second doped mediums. An absorbed beam input or coupling is configured to generate or receive at least one absorbed beam in a second wavelength range which is different from the first wavelength range, the absorbed beam being directed towards the first and second doped mediums. The first and second doped mediums have a higher beam absorption characteristic in the second wavelength range than in the first wavelength range, causing the absorbed beam to have a higher absorption than the energy beam in the first and second doped mediums and the first and second doped mediums each have a coating which allows transmission at both the first and the second wavelength ranges.

The gas in the scene is typically associated with a gas leak in equipment. To this end, the system comprises an infrared camera arrangement; a strobing illuminator device having a strobing frequency matched to a frame rate of the camera; and a processing arrangement. The processing arrangement is configured to store a prior frame obtained via the infrared camera arrangement; and compare a current frame with the stored prior frame and generate an output signal in response to said comparison. The system also comprises a display device configured to display an output image based at least on the output signal generated by the processing arrangement so as to facilitate detection of the particular predetermined gas, in use.

Abstract: An in-shell egg pasteurization process includes, in a temperature-raising stage (12), raising the temperature of yolk of a plurality of in-shell eggs (40), simultaneously and at least predominantly by means of microwave radiation, to a pasteurization temperature, the temperature-raising stage (12) including a plurality of elongate or longitudinally extending microwave cavities that are isolated from one another so that microwaves fed into an elongate or longitudinally extending microwave cavity do not leak into any other elongate or longitudinally extending microwave cavity. The in-shell eggs (40) are displaced along the lengths of the elongate or longitudinally extending microwave cavities whilst being irradiated with microwaves. In a pasteurization stage (14), the raised temperatures of the in-shell eggs (40) are maintained for a pasteurization time sufficient to pasteurize the in-shell eggs (40).
