The present invention relates to a food container evacuation module () capable of enhanced performances in terms of attainable vacuum and also being portable and easy to use, to a food container evacuation system () comprising it and to food containers () apt to be used in such food container evacuation system ().

Food container evacuation system comprising a food container evacuation module and food containers therefor

A getter pump is described. The getter pump has a casing and a getter cartridge mounted within the casing. Each cartridge has a linear central support and spaced getter elements mounted on the linear central support. Each cartridge is positioned along a plane orthogonal to the revolution axis and intersecting the midpoint of a linear central support. The angle formed by each positioning plane with its respective linear central support is comprised between 35&#xb0; and 75&#xb0;.

Getter devices with improved sorption rate, based on powders of quaternary alloys particularly suitable for hydrogen and carbon monoxide sorption, are described. Quaternary alloys having a composition comprising zirconium, vanadium, titanium and aluminum as main constituent elements are also described.

Non-evaporable getter alloys particularly suitable for hydrogen and carbon monoxide sorption

Solar connector receiver tubes with getter systems having a substantially toroidal shape are described.

Solar collectors receiver tubes

Getter materials are described. The getter materials have non-evaporable getter alloys in their powder form having high gas sorption efficiency, particularly for hydrogen, carbon oxide and nitrogen, which after having lost their functionality in consequence of the exposure to reactive gases at a first temperature, can then be reactivated through a thermal treatment at a temperature between 400&#xb0; C. and 600&#xb0; C. The alloy powders have as compositional elements titanium and silicon and at least one additional metallic element selected among vanadium, iron and aluminum and have an atomic percentage composition of the elements which can vary within the following ranges: 1. Titanium from 60 to 85 atomic percentage; 2. Silicon from 1 to 20 atomic percentage; and 3. The sum of vanadium, iron and aluminum from 10 to 30 atomic percentage.

Non-evaporable getter alloys reactivable after exposure to reactive gases

A solar collector receiver tube containing an improved getter system is described. The solar collector receiver tube has a base, pills of getter material that are uniform in height, and a containment metallic mesh having a non-uniform height and presenting at least one depression.

Improvements for solar collector receiver tubes

A flexible multi-layer getter with a gas-permeable layer covering a gas reservoir layer. In an embodiment, the gas-permeable layer covers part of the gas reservoir layer. In another embodiment, a barrier covers part of the gas reservoir layer. The barrier may include a foil substrate, a passivation layer, or a gas-permeable layer.

Flexible multi-layered getter

Getter devices based on powders of alloys particularly suitable for hydrogen and nitrogen sorption are described. Such alloys have a composition including zirconium, vanadium, titanium and, optionally, one or more elements selected from iron, chromium, manganese, cobalt, nickel and aluminum.

Non-evaporable getter alloys particularly suitable for hydrogen and nitrogen sorption

Getter alloys particularly suitable for hydrogen sorption are described. The getter alloys include a first element consisting of yttrium or a yttrium equivalent mixture, the first element forming at least 30% by atoms of the alloy. A method for removing hydrogen from devices which are sensitive to the presence thereof and hydrogen-sensitive devices which contain the described getter alloys are also described.

A combined pumping system comprises a getter pump and an ion pump. The getter and ion pumps are mounted on a same flange and are arranged on the same side of the flange at two different points thereof. The flange can be mounted to a vacuum chamber, such that the combined pumping system evacuates the vacuum chamber.

Combined pumping system comprising a getter pump and an ion pump

A combined pumping system comprising a getter pump and an ion pump is described. The getter pump and the ion pump are mounted in series on a same flange and are respectively arranged on opposite sides thereof so that both getter and ion pumps conductance are maximized towards gas flux sources in a vacuum chamber in order to improve the vacuum level of the system.

A process is provided for the formation of miniaturized getter deposits, comprising the steps of forming a layer of a photosensitive polymeric material on a support; selectively exposing the polymeric layer in order to cause a chemical modification in a portion of the polymeric layer; removing with a first solvent only one of the previously exposed or the not previously exposed portions of the polymeric layer, thus forming cavities in the polymeric layer; forming a thin layer of a getter material by cathodic deposition at the bottom of the cavity and on the residual polymer; and removing with a second solvent the polymer portion not removed by the first solvent, leaving at least a getter material deposit on the support surface.

Process for the formation of miniaturized getter deposits and getter deposits so obtained

Getter multilayer structures are disclosed, embodiments of which include at least a layer of a non-evaporable getter alloy having a low activation temperature over a layer of a different non-evaporable getter material having high specific surface area, both preferably obtained by cathodic deposition. The multilayer NEG structures exhibit better gas sorbing characteristics and lower activation temperature lower than those of deposits made up of a single material. A process for manufacturing such structures includes depositing a first, high surface area NEG film on a support, and then depositing a thin over layer of low activation NEG film.
