Abstract: An operating room light fixture with a light fixture housing, in which at least one lighting unit with at least one light source is arranged, with a handle, which is arranged on a side of the light fixture housing facing the operating area, wherein the handle comprises a control element for setting and/or adjusting the luminous intensity of the light source.

Abstract: An operating room light fixture having a first lighting unit including a first light source and an external reflector, a second lighting unit including a second light source and an internal reflector, and a control unit. The second lighting unit is positioned in front of the first lighting unit with respect to the direction in which the light emerges from the light fixture. The control unit may be actuated by a rotary element located in a handle of the light fixture. A heat reflection filter may be provided for adjusting the color temperature of the light fixture to a desired value.

Abstract: An operating room light fixture is provided with two lighting units (3, 4) in a light fixture housing. The first lighting unit (3) is used to generate a surface light and the second lighting unit (4), which is arranged after the first lighting unit (3) in the direction (7) in which the light emerges, generates an in-depth illumination.

Abstract: The present invention pertains to an operating room light fixture with a light fixture housing, in which at least one lighting unit with at least one light source is arranged, with a handle, which is arranged on a side of the light fixture housing facing the operating area, wherein the handle comprises a control element for setting and/or adjusting the luminous intensity of the light source.

Abstract: A supply unit for supplying a workplace with electricity and/or gaseous media, with a first, vertically extending supply duct and a second, vertically extending supply duct, wherein the electricity and the media are led to connections on at least one of the supply ducts. From these connections the workplace is supplied and improved such that the ergonomically most favorable arrangement of the supply tubes and electric lines leading to the connections will be possible. This object is accomplished by a section of the side surfaces having an angle of inclination less than 90.degree. in relation to the base such that the ends of the side surfaces pointing away from the base can be connected at a common junction. The connections are arranged exclusively on the outer side surfaces and that the distance between the supply ducts is such that the workplace can be brought into the space between the supply ducts.

Abstract: A device with an extraction fan for use for drawing off ambient air loaded with harmful substances during, e.g., laser surgery or HF surgery, is passed through a filter device. For routine use, easy replacement of the filter should be possible, its loading time is prolonged, and the arrangement of the filter does not compromise the easy handling of the suction line. To achieve this, a transparent sleeve 6, into which a cylindrical folded filter 10 is pulled via a perforation support tube 26, is installed in the suction line, or the filter has a hole 29 provided with a support lining, so that the filter can be directly attached to the suction-side connecting branch 5. The filter 10 is flown through radially, and thus it offers a large filter surface at minimum extension.

Abstract: A process for producing a filter with multiple folds from an aqueous fiber mixture that is applied to a porous form, in which a paper-like filter mat is produced on the form under the action of pressure, and it is carried out without mechanical deformation of the rough casting. This is achieved pursuant to the invention by the fact that the aqueous fiber mixture is deposited on the porous form having the contour of the filter, from loading chambers separate from one another, and the filter is built up of adjacent fold sections in layers on the form by separate introduction of the fiber mixture to the fold sections connected to one another.
