摘要:
A method of sterilizing packaging means (10) and, in particular, plastics material pre-forms (10), wherein the packaging means (10) are conveyed with a conveying device (2) and wherein at least one area of the packaging means (10) is acted upon with a flowable medium by a stressing device (4). According to the invention the medium applied to the area is subjected to irradiation with electromagnetic radiation in order to produce singlet oxygen, wherein this singlet oxygen is used to sterilize the packaging means (10).
摘要:
A plasma processing plant for plastic bottles, having a vacuum chamber arranged inside the processing chamber and when a respective bottle opening is pressed against a valve, the valve will open and establish a connection between the interior of the bottle and the vacuum chamber, and the chambers are continuously sealed against one another in a gastight fashion. With such approach, the gas can be conducted more easily and the number of control mechanisms can be reduced.

A magnet system with a magnet arrangement (M), a working volume (V) and a pulse tube cooler (P) with magnetic regenerator material (r) is characterized in that a shielding (m) of magnetic material is provided which reduces the stray field of the magnet arrangement at the location of the magnetic regenerator material (r) and is characterized in that ⅓|{tilde over (m)}RegR|+|mMagΔx|
摘要:
A roof fan having an air-quieting casing or sound reducing device on the suction side. A blower is mounted inside a housing and the impeller shaft extends vertically. The blower and the surrounding housing are pivotally arranged on the casing so that not only the blower is rendered accessible but also the sound reducing devices and the suction channel.

The method relates to a method for producing a strand-like, particularly band-like semi-finished part for electrical contacts, wherein the semi-finished part has a top side intended for making the electrical contact, said top side made from a silver-based composite material in which one or multiple metal oxides or carbon are embedded, and has a carrier layer supporting the composite material made of easily solderable or weldable ignoble metal, and method having the following steps: Powder-metallurgic production of a block made from the silver-based composite material, encasing of the block made of the composite material with a powder made from the easily solderable or weldable ignoble metal, compressing the block, encased by the metal powder, to condense the metal powder, sintering the compressed block in a reducing atmosphere or in an inert atmosphere or in a vacuum, avoiding the formation of fluid eutectics from the silver of the composite material and from the non-precious metal with which the block made from the silver-based composite material is encased, reshaping of the sintered block by extrusion pressing, creating a partial strand with a top side made from composite material and a bottom side made from non-precious metal.
摘要:
A device for transporting containers and in particular plastic containers has a main carrier rotatable about a pre-specified main axis D, with a multiplicity of transport elements for transporting the plastic containers. Each of the transport elements is arranged on an arm and can swivel in relation to the main carrier about a pre-specified geometric pivot axis. A multiplicity of independently controllable first drives is provided to generate the swivel movements of the transport elements. Each transport element is also mobile linear in relation to the pivot axis about which it is pivotable, and a multiplicity of independently controllable second drives is provided to generate the linear movement of the transport elements.
