IPC: C09B1/16
Filed: 1928-01-09
Abstract: 315,328. Barnes, R. S., Harris, J. E. G., Wylam, B., Thomas, J., and Scottish Dyes, Ltd. Jan. 9, 1928. Samples furnished. Anthraquinone dyes. -Vat dyes which are apparentlv anthraquinone-acridones are obtained by heating arylido-anthraquinone-o-carboxylic acids or their leuco compounds, whether the carboxylic group be in the side chain or in the anthraquinone nucleus, with sulphuric anhydride compounds of tertiary bases in the presence of a tertiary base.. By heating the arylidoanthraquinone-o-carboxylic acids with sulphuric anhydride compounds of tertiary bases in the presence of a non-basic organic solvent, products are obtained which are either vat dyes or acid wool dyes according to the parent materials employed. In examples, (1) 1-#-naphthylaminoanthraquinone-2-carboxylic acid, or its leuco compound obtained by vatting with caustic soda and hydrosulphite and precipitating with dilute sulphuric acid, is heated with pyridine sulphuric anhydride and pyridine or nitrobenzene: the product appears to consist substantially of anthraquinone-1 : 2-naphthacridone in each case; (2) 1-anilidoanthraquinone-2-carboxylic acid is heated with pyridine sulphuric anhydride and nitrobenzene; the product dyes wool in bright red shades from an acid bath: (3) the leuco compound of 1-anilidoanthraquinone-2-carboxylic acid, obtained by precipitation from the vat with acetic acid, is heated with pyridine sulphuric anhydride and pyridine in an atmosphere of nitrogen: the product dyes cotton from the vat in red shades which change to reddish-violet on oxidation in the air In place of pyridine sulphuric anhydride, substances which produce this compound on reaction with pyridine, for example, chlorsulphonic acid, acid sulphuric halides, and oleum, may be employed in presence of pyridine. The 1-anilido-o-carboxylic acid and 1 : 5-dianilido-o: o'-dicarboxylic acid derivatives of anthraquinone are mentioned as examples of parent materials in which the carboxylic group is in the side chain.

Title: Improvements in or relating to an extruder
Inventor: VESILIND PAUL EDUARD
IPC: B29C48/67
Filed: 1965-01-07
Abstract: 1,075,189. Extrusion machines. KOPPERS CO. Inc. Jan. 7, 1965, No. 832/65. Heading B5A. [Also in Division B1] In an extrusion moulding machine for use in producing expanded or expandable thermoplastic polymeric material, the screw is provided with integral chokes 82, 84, 86, 88 etc. which divide the barrel 18 into annular channels 80d, 80e, 80f, 80g etc. whose volumes sequentially increase towards the exit end of the barrel and wherein the respective screw flights 79d, 79e, 79f, 79g &c. are formed with sequentially decreasing pitch so that the throughput of the machine remains constant. Each choke, Fig. 3 (not shown), is provided with axial grooves (98), and a cylindrical portion (94) is situated adjacent an inlet, as at (31), which is used for the introduction of liquid or gaseous material under pressure, e.g. a blowing agent, into the grooves of the choke as the latter rotates. By this means plasticized material passing from one side of each choke to the other has thoroughly admixed therewith material from inlets 31, 30, 29, 28 &c., Fig. 1. Prior to choke 82, material entering from a hopper 14 is plasticized in passing from annular channel 80a to channels 80b and 80c. The increase in volume of the annular channels 80d, 80e, 80f, 80g etc. allows cooling of the foaming agent/ thermoplastic mix with consequent rise in viscosity thereof, Fig. 7 (not shown), and ease of extrusion. In one embodiment, Fig. 5 (not shown), foamable polystyrene beads are made by injecting expanding agent, e.g. pentane, through lines (29), (30) and (31), with line (28) used likewise or for the injection of additives such as plasticizers, dyes, light stabilizing agents, antioxidants or flame-retarding agents. A multi-orifice die (132) produces strands of extrudate (134), shock-cooled by water in a bath (136) to prevent expansion, and the strands are granulated by a chopper (142). In a second embodiment, Fig. 6 (not shown), a foam film (154) is produced continuously from die head (152), which is blown, collapsed by plates (156), slit by a device (164) and collected in the form of two sheets by rolls (170), (172). Other polymeric thermoplastic materials mentioned include homopolymers and copolymers derived from hydrocarbon vinyl monomers and in particular impact polystyrene, i.e. an admixture of polystyrene with natural or synthetic rubber. Various blowing agents are mentioned, the preferred variety being voltatile organic compounds of a saturated aliphatic hydrocarbon containing from 4-7 carbon atoms in the molecule and perchlorofluoro carbons, which compounds have a molecular weight of at least 58 and a boiling point not greater than 95 C. and are added in amounts of up to 15 parts by weight per 100 parts by weight of polymer. The cell size of the resulting product may be controlled by using an agent such as a carbon dioxide liberating material and boric acid or an organic acid having at least about 3À0 milliequivalents of acidic hydrogen per gram, which agent may be added via hopper 14.

IPC: H01L23/52
Filed: 1992-01-06
Abstract: PURPOSE:To form a metal thin film which is free from a tensile stress on the surface of a semiconductor substrate by a method wherein a thin film composed of a material whose coefficient of thermal expansion is larger than that of the semiconductor substrate is formed in advance on the rear of the semiconductor substrate, the metal thin film is formed on the surface and, after that, the thin film on the rear is removed. CONSTITUTION:An aluminum film 2 as a material whose coefficient of thermal expansion is larger than that of a semiconductor substrate 1 is formed on the rear of the semiconductor substrate 1 at a temperature which is higher than that in the formation of a metal thin film 3 to be formed after that. Thereby, the surface of the semiconductor substrate 1 is set to a state that a tensile stress has been exerted. Then, the metal thin film 3 composed of aluminum or the like as a wiring material is formed on the surface of the semiconductor substrate 1. At this time, when the temperature of the substrate is returned to room temperature, the substrate is set to a nearly horizontal state. Then, the whole surface of the metal thin film 3 on the surface of the semiconductor substrate 1 is coated with a a resist; the aluminum thin film 2 on the rear is etched and removed. Thereby, a metal film in which a stress migration is hard to cause can be formed on the surface of the substrate.

Abstract: PURPOSE:To make it possible to suppress the re-release of a phosphorus component into treated water and to remarkably enhance the removal efficiency of phosphorus from sewage, by shortening the stay time of precipitated sludge in a precipitation tank as possible. CONSTITUTION:Sewage and activated sludge are mixed to be subjected to aeration treatment in an aeration tank 2 and sludge is precipitated in a precipitation tank 3 to flow treated water out of a system while the part of precipitated sludge is returned to the mixing and aeration treatment process with sewage. In this sewage treatment method, the stay time of the precipitated sludge in the precipitation tank 3 is shortened as possible. For the sake of shortening stay time, for example, it is expedient that an inclined plate type precipitation tank is employed but, as other means, a mechanical concentrating process 7 due to a centrifugal concentrator is provided between the tank 3 and a sludge tank 4. As the result, the re-release of a phosphorus component into treated water caused by making the tank 3 anaerobic can be prevented and the removal efficiency of phosphorus from sewage can be extremely enhanced.
