Abstract: ABSTRACT:         A method of manufacturing a semiconductor device in which layers of silicon nitride and silicon oxide are etched by bringing the layers into contact with constitu-ents of a plasma which is formed in a gas mixture which contains a fluoride compound and an oxygen compound.  By addition of from 1 to 15% by volume of a gaseous compound which contains a halogen other than fluoride to the gas mixture, silicon nitride layers can be etched away at least five times faster than silicon oxide layers.  The method is thus suitable in practice, for example, for manufacturing a silicon nitride mask for the formation of a field oxide in LOCOS processes.

Abstract: Abstract of the Disclosure. A cation exchanger is produced by treating comminuted bark in separate steps with an alkali hydroxide solution of at least 5% by weight, preferably 20-40% by weight, and with 30-75% by weight sulphuric acid, preferably 50-65% by weight. After each step washing with water is performed until the pH-value after the alkali hydroxide treatment goes below 9 and after the sulphuric acid treatment goes above 3. Preferably, the treatment with alkali hydroxide precedes the treatment with sulphuric acid. The treatment with alkali hydroxide is carried out for .5-20 hours, preferably 3-10 hours, and the treat-ment with sulphuric acid is carried out from .5-8 hours, preferably from 1-6 hours. The cation exchanger can be regenerated with alka-li hydroxide solution, particularly sodium hydroxide solution.            The cation exchanger is suitable for the purification of waste water and can be produced at low cost.

Abstract: Abstract The specification describes a membrane osmometer having a pressure measuring chamber for receiving the pure solvent, a test chamber open to the atmosphere for receiving the solution which is to be tested, and a semipermeable membrane resting on a support plate.  The invention sets out to perform four functions with only one sealing ring, when the test chamber and pressure measuring chamber of the osmometer are fitted together: a)  stretching the membrane outwards in the direction of the membrane surface b)  effecting a seal at the surface of the membrane facing the test chamber c)  sealing off the pressure measuring chamber d)  sealing off the test chamber to prevent the test sample from running out. This aim is achieved by the fact that, on its side facing the membrane, the test chamber has a conical annular surface which, when the test chamber and pressure measuring chamber are fitted together, presses a sealing ring both against the surface of the membrane which faces the test chamber and also against a cylindrical inner surface of the pressure measuring chamber.

Abstract: SYSTEM FOR LOCATING CORES IN CASTING MOLDS                Abstract Of The Disclosure A method and a support structure for use in casting metal articles which define at least one internal passage and wherein the support structure is associated with a core or cores employed during the casting opera-tion.  In that operation, the cores are confined within a disposable pattern, and a ceramic mold is formed around the pattern.  When the pattern material is removed, a mold cavity is provided with the core positioned in the cavity to form the desired opening in the cast article.  The sup port structure for the core comprises a member positioned between the core surface and the opposing  mold surface.          This member is encompassed by the pattern material when the pattern material is formed around the core.  During the subsequent removal of the pattern material and also during curing of the ceramic mold, the support member serves to hold the core in place so that the dimension of the casting wall surrounding the internal passage can be precisely maintained.  The support is of a material which will be diffused into the casting alloy so that the cast-ing properties will not be adversely affected. Further-more, no significant surface finishing operations are re-quired for the casting.
