Inventor: SILVANO FRETI
IPC: G01N33/20
Filed: 1983-05-04
Abstract: A process for measuring the rate of oxidation on the surface of a metal melt wherein the oxide skin on the melt surface is removed at constant temperature and the electromagnetic radiation during the subsequent oxidation is measured with an infra-red radiation pyrometer such that the variation in intensity of the electromagnetic radiation indicates the rate of oxidation. The process can also be employed for measuring the concentration in a metal melt of the elements influencing the rate of oxidation.

Abstract: Die Profilleiste besitzt zwei in Profillängsrichtung im Abstand voneinander verlaufende, durch einen Steg miteinander verbundene Schenke, an deren vom Steg entfernte Ende je ein nach innen gerichteter, sich etwa in Parallellage zum Steg und in Profillängsrichtung erstreckender Flansch angeformt ist. Die Schenkel sind mit wenigstens je einer versteifenden, sich in Profillängsrichtung erstreckenden Längseinprägung versehen und zusätzlich zu diesen Längseinprägungen mit quer zur Profillängserstreckung verlaufenden, unter etwa gleichen Abständen voneinander angeordneten Quersicken ausgerüstet, die sich über die gesa-mten Schenkelhöhen erstrecken oder auch nur bis an einen Randstreifen reichen können, der sich längs der vom Steg entfernten freien Schenkelenden, an die die nach innen gerichteten Flanschen angeformt sind, erstreckt. Die Quersicken können profilinnenseitig oder -außenseitig aus dem Schenkel-und/oder Stegmaterial herausgeformt sein. Sie tragen neben den übrigen Maßnahmen zur Erhöhung der Formstabilität zu einer Verbesserung der Steifigkeit und Tragfähigkeit bei derartigen Profilleisten bei.

Abstract: Gegenstand der Erfindung ist ein Verfahren zur Stabilisierung wäßriger Lösungen von Acetoacetamiden, bei dem gleichzeitig der Gehalt an β-Aminocrotonsäureamiden vermindert wird. Dabei werden die wäßrigen Acetoacetamidlösungen, die in bekannter Weise durch Umsetzung von Ammoniak oder wasserlöslichen, primären oder sekundären aliphatischen Aminen unter basischen Bedingungen hergestellt worden sind, unmittelbar nach ihrer Herstellung bei Raumtemperatur unter guter Durchmischung mit Diketen in einer zur Aufrechterhaltung eines pH-Wertes von 6 bis 7 ausreichenden Menge versetzt. Die so hergestellten wäßrigen Lösungen der Acetoacetamide sind nicht zur weitgehend stabil, sondern auch besonders rein, da die stabilisierten Lösungen weder durch salzartige Nebenprodukte noch durch Folgeprodukte von β-Aminocrotonsäureamiden verunreinigt sind.

Abstract: Photosensitive sheet handling apparatus and method for phototypesetters. Accurate control of the lateral positioning of the sheet (i.e. film) is provided by the use of tapered drive rolls (24). The apparatus includes an input cassette (2), a film input drive assembly (7) comprised of tapered pinch rollers ' (8, 10) and a film edge locating stop, a slightly tapered vacuum film drive drum (24) having a collar or flange on one side in accurate alignment with the rollers, a motor operated output drive assembly (56) also comprised of tapered pinch rollers and a film edge locating stop in accurate alignment with the drum flange, and a periodically operated film winding mechanism (142) located within an output cassette (42). The tapered rolls urge one edge of the film against the flange of the drum (24) and stops of the pinch rollers (8, 36) to maintain accurate alignment. Chambers (62, 84) are provided for receiving loops of film at the input and output sides of the drum (24). The film moves forwardly for leading, and moves in the reverse direction for reverse leading. During the reverse motion, film is withdrawn from one of the loops while another loop is formed to take up the film. This avoids the scratching and wear which otherwise would occur by repeatedly passing the film through the pinch rollers (7, 56). The film winding mechanism (142) in the output cassette winds the film under tension, but periodically relieves the tension in order to prevent the film from jamming in the output cassette (42).

Abstract: The device possesses, in one part (1), two bolts (8, 9) connected to one another by means of a web (16) and a tension pin (21). By means of a pulse transmitter (59) arranged in another part (2), a blocking disc (34) can be released which, as a result of the pivoting of an angle lever (31), releases an opening lever (35) which is actuated by a compression spring (22). The opening lever (25) thus displaces the two bolts (8, 9) into the opening position. The tension pin (21) extends through the end plate (4), thereby relieving the spring (22), and the bolts (8, 9) are pushed forwards by a leaf and helical spring (18) and the blocking disc (34) is reset. Opening without a key is possible from one side of the parts (1, 2), whilst from the other side the other bolt (9) can be opened via a pivoting lever (49). For pulse transmission to the electromagnet (38), a contact plate (57) is embedded in the end plate (4) and is connected to the electromagnet (38) by means of a line (58). This arrangement makes it virtually impossible for the electromagnet (38) to be actuated in an unauthorised way. <IMAGE>

Abstract: A process for producing an aqueous solution of a straight-chain alkyl tertiary amine oxide and a branched-chain alkyl tertiary amine oxide by reacting aliphatic tertiary amines with a aqueous solution of hydrogen peroxide is disclosed. In this process, a tertiary amine which mainly consists of a branched-chain tertiary amine is first reacted with excess hydrogen peroxide, and then, a straight-chain alkyl tertiary amine which is substantially free of a branched-chain alkyl group is added to the reaction mixture for permitting further reaction with hydrogen peroxide. The process achieves a high overall conversion of the starting amines, and the final product has an extremely low level of residual hydrogen peroxide.

Abstract: Molded articles formed of polystyrene or other polymers containing an aromatic moiety can be derivatized on the surface of the article by subjecting the molded article to a chemical reaction wherein the reaction media utilizes tetramethylsulfone as the reactant solvent and a suitable substituent group which is substituted on to the aromatic moiety of the polystyrene or other polymer by electrophilic substitution. By choosing the substituent group to further include a leaving group, further substitution of the primary substituent can be effected normally by nucleophilic substitution reaction. In this way, biologically important molecules can be attached to a polystyrene or other aromatic containing polymer without effecting certain properties of the molded article such as its optical or spectroscopic clarity.

Abstract: The invention relates to a pneumatic spacing drill with a seed container and suction chamber separated from one another by a rotating disc-shaped separating member which is guided through the seed stock in the seed container by means of projections arranged at distances from one another in the circumferential direction of the separating member. Each projection is arranged in the region of the mouth, remote from the suction chamber, of in each case one hole extending through the separating member and in communication with the suction chamber. Furthermore, the suction chamber extends along part of the path of the holes and the vacuum is interrupted at a particular point along the path. The object of the invention is to provide a simplified spacing drill for the improved separation of the seeds. This is achieved in that each projection is arranged on the side of the respective hole leading in the direction of rotation of the separating member, so that it at least partially masks the respective hole. <IMAGE>
