The present invention relates to an irradiation device having a radiation source and a filter which is arranged in the optical path and has two transparent filter disks which are substantially arranged in parallel with each other and which are held with their surrounding edges in a frame made of a material of good heat conduction, the filter disks and the frame defining a closed cavity which has provided therein a medium which selectively influences the radiation spectrum. In order to improve an irradiation device such that a degassing of the medium is prevented during heating and the filter disks do not deform as the pressure increases, provision is made for the cavity to be in the form of a pressure chamber, so that during operation of the irradiation device overpressure prevails in the cavity, and for the filter disks to be made of glass ceramic or mineral glass, wherein the filter disk which is arranged closer to the radiation source is in the form of a safety device such that it is more susceptible to breaking than the filter disk which is further away from the radiation source.

Irradiation device with filter disks and medium enclosed therebetween

A radiation apparatus comprising a radiation source and a filter arranged in an optical path, said filter comprising two transparent filter discs which are arranged substantially in plane-parallel fashion relative to each other and which are held with their surrounding edges in a frame made of a material of good heat conduction, the filter discs and the frame defining a closed cavity which has provided therein a medium for selectively influencing the radiation spectrum. The frame is divided substantially in a direction transverse to the filter axis into first and second frame halves in such a manner that the one filter disc is arranged on the first frame half at the side facing the cavity and the other filter disc is arranged on the second frame half at the side facing the cavity.

Radiation apparatus

Method and apparatus for electrostatically precipitating impurities,

In an infrared radiation lamp, the optical path has provided therein a cuvette which is filled with a liquid containing water and a fungicidal agent. The cuvette consists of two opposite transparent panes and a casing receiving said panes. The liquid inside the cuvette is a buffer solution with a pH of 7, preferably based on phosphate.

Combined coffee filter and support base

A filtering device for the preparation of coffee, with a pot-shaped vessel, at the bottom of which a sieve sheet is attached, and with a water distribution plate, which is adapted to be supported by the upper edge of the vessel. The diameter of the water distribution plate is smaller than the inner diameter of the vessel, and a plurality of feet protrude from the edge of the water distribution plate nearly perpendicularly to the surface of the same. The free ends of the feet each form a shoulder, which serve to rest on the upper edge of the vessel such that the water distribution plate lies within the interior of the vessel and leaves a circumferential clearance to the same. Hot water which is poured onto the water distribution plate flows through that clearance onto the coffee powder. The water distribution plate may be removed from the vessel and laid onto a surface with its feet down as a base plate for the vessel, thus collecting water that might still pass through the filter. A rim protruding from the circumference of the water distribution plate prevents water from flowing down when the same is used as a base plate.
