Patent number: 4939374Abstract: An irradiation device which includes a radiation source arranged within a housing and a filter arranged in the ray path of the radiation source which consists of two transparent, essentially plane-parallel discs. The discs are held in a frame and a medium which selectively influences the spectrum of the rays of the radiation source is provided between the discs. A plurality of outwardly projecting cooling fins are arranged on the outer circumference of the frame and serve in conjunction with the medium between the disc and the frame to dissipate heat from the medium.Type: GrantFiled: October 14, 1988Date of Patent: July 3, 1990Assignee: Maxs AGInventor: Albert Greutert

Patent number: 4872266Abstract: In a box-type plastic frame having longitudinal strut portions in which a vaulted shearing foil is embedded and transverse strut portions made of a resilient material in order to facilitate the insertion of the plastic frame shearing foil unit into a shearing head casing member.Type: GrantFiled: January 21, 1988Date of Patent: October 10, 1989Assignee: Maxs AGInventors: Albert Greutert, Ruedi Gasser
-
Patent number: 4740303Abstract: A metal filter foil has elongated slits forming the filter openings. The slits are arranged in a plurality of groups. In each group the slits are parallel to one another, and the slits of different groups form an angle with one another.Type: GrantFiled: December 3, 1986Date of Patent: April 26, 1988Assignee: Maxs AGInventors: Albert Greutert, Ruedi Gasser
-
Patent number: 4619048Abstract: A shaving head for dry razors in which a perforated shaving foil is connected to a plastic frame is produced by placing the shaving foil in an injection mould and holding it in thermal contact with the wall of the injection mould on one side while the plastic frame is injection-moulded in order to limit the rise in the temperature of the shaving foil during the injection-moulding process.Type: GrantFiled: April 25, 1984Date of Patent: October 28, 1986Inventor: Albert Greutert
-
Patent number: 4476776Abstract: A centrifuge cage for coffee centrifuges or juice extractors is in two parts. The top part or member can be moved axially relatively to the bottom part between a closed position, in which the centrifuge cage is sealing tight along the boundary zone on its periphery, the same having a mesh zone, and an open position, in which the filtered material can be hurled outwards from the centrifuge cage.Type: GrantFiled: June 24, 1982Date of Patent: October 16, 1984Assignee: Maxs AGInventors: Albert Greutert, Ruedy Gasser

Patent number: 4374026Abstract: Disclosed is an improved basket filter which minimizes raw material waste and is formed of at least one rectangular perforated metal foil part folded along a bending line at its middle, transversely to its longitudinal edge, and at least two perforated metal foil elements in the form of sectors of a circle. The longitudinal edges of the rectangular metal foil part are connected to the straight line edges of the metal foil elements in the form of sectors of a circle so that, after assembly, the filter defines a round opening which merges into a straight line bottom edge. Adjoining edges between the rectangular metal foil part and the straight line edges of the metal foil elements are embedded in a plastic.Type: GrantFiled: April 20, 1981Date of Patent: February 15, 1983Assignee: Maxs AGInventor: Albert Greutert

Patent number: 4287066Abstract: A sieve sheet having radially extending separating slots in order to subdivide the area of the sieve sheet into sieve segments. The separating slots are embedded with plastics material. The sieve segments may be arranged in a configuration differing slightly from a plane, thus stiffening the sieve.Type: GrantFiled: September 8, 1976Date of Patent: September 1, 1981Assignee: Elfo AG SachselnInventors: Albert Greutert, Ernst Stumvoll

Patent number: 4259283Abstract: The invention relates to a method of manufacturing a sieve which is composed of several planar sieve sheet sections, which are lying adjacent each other and are separated by a plurality of slots and are communicating with one another at a common point. The sieve sheet sections when so arranged are placed into a mold, and thereafter plastics material is introduced into the mold to form ribs that are covering the slots and that are holding in place and stiffening the rims of the sections that form a slot. The sieve sheet may be formed as an integral part or alternatively may be made of several sieve sheet sections that are held together at the peripheral region by connecting means. The plastics ribs covering the slots may be integrally formed with a container holding the sieve sheet.Type: GrantFiled: April 20, 1979Date of Patent: March 31, 1981Assignee: Elfo AG SachselnInventors: Albert Greutert, Ernst Stumvoll
-
Patent number: 4256585Abstract: This invention relates to a coffee filter comprising a drip catcher, a container and a filter insert designed to be introduced into the container, the filter insert comprising filter surfaces of a perforated metal foil and the container comprising a single outflow opening in its base.Type: GrantFiled: April 21, 1980Date of Patent: March 17, 1981Assignee: Maxs AGInventor: Albert Greutert
-
Patent number: 4255265Abstract: This invention relates to a permanently useable coffee filter comprising a funnel-shaped container, of which the base is provided with at least one outlet opening, and a funnel-shaped filter insert which is inserted into the container and of which the filter surface is situated at a distance from the wall of the container.Type: GrantFiled: April 21, 1980Date of Patent: March 10, 1981Assignee: Maxs AGInventor: Albert Greutert

Patent number: 4231876Abstract: A coffee filter which may be used repeatedly is described. It comprises a funnel-shaped housing having an outlet port at the lower end. A filter of similar shape is fitted into the housing and is so dimensioned as to provide a clearance of between 0.2 to 1.5 mm. The filtering element is so dimensioned that the upper rim thereof forms a seal with the inner wall of the housing. The outlet port of the housing has a restriction in order to assume a continuous flow of the filtrate between the funnel-shaped housing and the filtering element.Type: GrantFiled: February 15, 1979Date of Patent: November 4, 1980Assignee: MAXS AktiengesellschaftInventors: Anton Zimmermann, Albert Greutert
-
Patent number: 3980563Abstract: A shaped sieve body that is made of a perforated metal foil, which is formed to a shaped body. Said body comprises at least one foil element provided along its connecting edges with anchoring means that are embedded in plastics. The foil element has a form allowing to spread said foil element in a plane.Type: GrantFiled: October 27, 1972Date of Patent: September 14, 1976Assignee: Interelectric AGInventors: Albert Greutert, Ernst Heidborn
-
Patent number: 3935112Abstract: A reusable coffee filter with a pot-shaped hotwater container and a filter strainer adjacent an opening in the bottom of said container. The filter strainer is made of metallic sieve sheets having perforations flaring out in the flow direction. On top of the hotwater container a distribution plate is supportably held which has a plurality of holes distributed over an area corresponding to the vertical projection of the opening of the filter strainer in order to ensure a good wetting and extraction efficiency of the coffee powder.Type: GrantFiled: July 8, 1974Date of Patent: January 27, 1976Assignee: Interelectric AGInventor: Albert Greutert
