Abstract: The invention relates to an optical fiber system for generating a side-emitting optical scattered laser radiation from a coupled optical laser radiation consisting of at least one side-emitting optical fiber with a fiber input and a fiber output, wherein the side-emitting optical fiber has at least one fiber core, a scattering layer surrounding the fiber core, and at least one cladding layer surrounding the scattering layer, wherein by the scattering layer, side-emitting scattered laser radiation is generated from the optical laser radiation coupled into the optical fiber, and wherein a coupling-side connecting section of the side-emitting optical fiber at the fiber input is received in a fiber connector and to produce a mechanical connection to the fiber connector. Particularly, at least the scattering layer and the at least one cladding layer are removed by stripping to suppress the side-emitting scattered laser radiation in the connecting section at the free end.

Abstract: In a machine (1) for the treatment or processing of foodstuffs, e.g. the slicing of sausage, the incidence of contamination by germs in the casing (3) of the machine (1) is reduced by the provision of a heater arranged to heat the casing (3) and/or air contained within it to an elevated temperature. Most preferably, the heater comprises means (32,14) for heating and circulating air in the casing (3) and means (9) for directly heating the casing (3) itself.

Abstract: An apparatus for inserting stacks of goods (1), for example sausage slices, into hollow containers (4) for packaging, the interior size of the hollow containers (4) corresponding substantially to the dimensions of the goods, includes grippers (2, 7) some of which (7) remain substantially above the edge of the opening of the hollow containers during the insertion procedure and some of which (2) are insertable slightly in the opening to facilitate depositing the goods in the desired position for packaging. Extension members (5) which grip below the goods for packaging can also be provided.

Abstract: In a vacuum packaging machine having a forming station and an evacuation and sealing station, wherein each station has a chamber made of an upper and a lower part, and each part comprises a base portion (top cover or floor, as the case may be) and four upstanding walls, one or both of said chamber parts is made from material having an appropriate cross-sectional shape, preferably U-shaped, forming the base portion and opposite side walls, the front and rear walls being secured thereto in the form of covers. The cross-sectional shape may be double U-shaped, providing accommodation for connections for chamber supply requirements (vacuum, air, power). Also the cooling plate for the lower part is secured on the under-side of the floor of said part and mounts it on the means for imparting chamber opening and closing movement to the lower part, while the cooling plate for the upper part is inside the chamber, on the under-side of the top cover.
