Franz Scheidl has filed for patents to protect the following inventions. Microwavable bag with valve and method for the fabrication thereof. Patent number: Abstract: In a reclosable bag 20 a zipper Z is provided on the inner surfaces 50 of the plastic film and the two parts of the zipper Z are fixed on the opposite inner surfaces 50 of the bag 20 , wherein the zipper Z is connected to the inner surface 50 of the plastic film in such a manner that between the welded regions 12, 14 between the zipper Z and the inner surface 50 of the plastic film, recesses 15, 13 are left free in the longitudinal direction of the zipper Z to form a seal-free longitudinal channel and in the transverse direction of the zipper Z to produce free air or steam passage openings at defined distances between the zipper Z and the inner surface 50 , through which openings a passage of steam is possible, wherein ends of the openings facing the interior 60 of the bag 20 are larger than ends of the openings facing the exterior 70 of the bag Type: Grant.
Filed: April 20, Date of Patent: December 17, Assignee: Mondi AG. Publication number: Type: Application.
Publication date: February 10, Terpene ethers. Abstract: The invention relates to new terpene ethers of the formula STR1 in which R denotes a cyclic or bicyclic radical or an alkyl radical which is substituted by cyclic, bicyclic or tricyclic radicals, optionally via an oxygen bridge.
The compounds are prepared by reaction of camphene with alcohols R--OH, in which R represents one of the above-mentioned radicals. The new ethers are used in the field of aroma substances and solvents, and as intermediates for plant protection agents, agents for combating pests and medicaments.
Filed: July 25, Date of Patent: May 20, Assignee: Hoechst Aktiengesellschaft. Inventors: Franz Scheidl, Manfred Gscheidmeier. Epoxide resins containing phenol groups, their manufacture and their use. Abstract: The present invention relates to epoxide resins containing phenol groups and to homo-oligomers thereof of the structure STR1 that are obtained by reacting phenolcarboxylic acids with one epoxide equivalent of a polyepoxide.
The new compounds are difficultly volatile and resistant to migration and can be used as stabilizers in synthetic polymers, in particular in poly-.
Filed: April 23, Date of Patent: December 29, Organotin compounds, the preparation and use thereof. Abstract: The invention provides novel organotin compounds and their preparation by reaction of organotin halides with mercaptans, thiocarboxylic acid esters, carboxylic acids or carboxylic acid partial esters. The novel compounds are used as starting for stabilizing halogen-containing polymers without influencing their transparency.
Filed: August 8, Date of Patent: December 2, Inventors: Helmut Korbanka, Franz Scheidl. Glycerol phosphites esterified with phenolcarboxylic acids. Abstract: The invention provides novel esters of glycerol, in which one of the OH groups of the glycerol is esterified with a phenolcarboxylic acid, while the two other OH groups are esterified with phosphoric or phosphorous acid, substituted by long-chain alcohols, amines, mercaptans or phenol compounds.
The products are suitable as light and heat stabilizers for plastics. They are distinguished by a high resistance to hydrolysis and extraction. Filed: March 12, Date of Patent: October 21, Organotin halides. Abstract: The invention provides novel organotin halides obtained by reaction of tin and hydrogen chloride with those olefins which carry a carbonyl group in adjacent position to the olefinic double bond and which are substituted in addition by at least one carboxylate group not adjacent to the double bond.
Filed: August 7, Date of Patent: May 13, Dicyclophosphites and organic polymers stabilized with said phosphites and their use as stabilizers. Abstract: The present invention is related to novel phosphites, their use as stabilizers for organic polymers, furthermore to stabilizer compositions containing these novel phosphites as well as the organic polymers being stabilized therewith. The novel phosphites have a good stabilization effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence.
Their volatility and tendency to exudation are very weak. Filed: July 5, Date of Patent: March 27, Inventors: Harald Haberlein, Franz Scheidl. Organic phosphites and their use as stabilizers. Their volatility and tendency to exudation are minimal. Filed: May 23, Date of Patent: December 12, Cyclic phosphites of sugar alcohols and polymers stabilized therewith. Abstract: The invention is related to novel phosphites of sugar alcohols, their use as stabilizers for organic polymers, furthermore to stabilizer compositions containing these novel phosphites as well as the organic polymers stabilized therewith.
The novel phosphites have a good stabilizing effect, especially in combination with known stabilizers, and they are substantially stable against hydrolytical influence. Filed: July 22, Date of Patent: November 14, Novel organo-tin compounds and their use as stabilizers. As compared to the known tin stabilizers, the tin compounds of the invention have improved stabilizing properties at identical tin content.
Filed: December 20, Date of Patent: October 24, Organic phosphites, process for their manufacture and their use as stabilizers. Filed: May 12, Date of Patent: October 3, Physiologically unobjectionable stabilizer compositions for halogenated polyolefins.
Abstract: The present invention is related to stabilizer compositions for the stabilization of molding compositions based on halogenated polyolefins, essentially consisting of aluminum salts of certain carboxylic acids, organic phosphites and substituted indoles. Further subject of the invention are the molding compositions which are stabilized with said stabilizers. The stabilizers according to the present invention show an excellent stabilizing effect. Filed: May 25, Date of Patent: November 29, Inventors: Franz Scheidl, Werner Sommer.
Stabilizer combination for halogen-containing polymers. Filed: September 23, Date of Patent: February 15, Inventors: Franz Scheidl, Herbert Nies.
