Title: Packaging materials for the protection of metals
IPC: C23F11/02
Filed: 1969-05-07
Abstract: 1,263,553. Anti-corrosion packaging. DAUBERT CHEMICAL CO. 7 May, 1969 [6 Aug., 1968], No. 23222/69. Heading B8C. A packaging material for protecting a wide range of metals and metal alloys comprises a solid carrier such as a wrapping sheet of paper, fabric, or plastics, and which embodies a small amount of 3-amino-1,2,4-triazole. The latter, which is non-toxic and non-hygroscopic, may be applied to the solid carrier by spraying and evaporating; by impregnating with the 3- amino-1,2,4-triazole compound dissolved in an organic solvent-water solution; or by coating, brushing &c. The compound is applied at 0.1-2 grams per square foot of area of sheet stock of, at least 0.05, and preferably from 5-10%, by weight, and can be used in combination with volatile amine carboxylates, volatile aromaticnitro-compounds, volatile amine salts of nitrosubstituted aromatic acids, volatile heterocyclic amine, and with compatible mixtures of these chemicals. The metal to be protected is cleaned and individually wrapped in the carrier or, several metal objects may be packaged in a carton having its interior surface either impregnated with the protective compound or, lined with protective sheets, the latter also being used to subdivide the carton into compartments, if so desired. The carrier, may be in the form of a laminate of heat sealable sheets comprising one film which incorporates a small proportion of 3-amino-1,2,4-triazole and another film which is resistant to the triazole. Other carriers described include diatomaceous earth, silica gel, and metal foils.

IPC: G01P5/06
Filed: 1954-08-10
Abstract: 765,206. Rotary meters. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Aug. 26, 1955 [Aug. 10, 1954], No. 23227/54. Class 110 (2). The meter has a rotor with axial vanes 4, on a spindle 5, and one or more entrances 13, for air or other gas, designed to convert the incoming gas into a jet or jets following a spiral path within the casing 1. The casing may be made of plastic material closed at one end 9, and the usual indicating mechanism 7 placed between the wall 9 and an outer cover protecting the indicator needles 8. The outer end 3 may be attached to a respirator base or to any other point to which the metered air or gas flow is to be directed. The vanes 4 may be of plastic material mounted on a light spindle 5 which may be supported in jewelled bearings 6. The rotor and indicating mechanism are carried by a framework constructed as a unit, which is removable as a whole from the stator. Different sized units may be used in the stator. The meter may be used in an anaesthetic apparatus. Fig. 5 (not shown) has a modification in which only a portion of the air stream passes through the meter, some air entering the stator by way of a weighted by-pass valve 17. Fig. 7 shows a further arrangement with inlet deflecting guidevanes 18 causing the air stream to spiral through the casing. The meter is insensitive to reverse air flow but a check valve may be provided to prevent expired air from passing back through the meter and thus to protect it from moisture. The meter may be used for measuring the velocity of the wind.

Title: A process for the production of 1-(3, 4, 5,-trialkoxyphenyl)-6, 7-dialkoxyisoquinolines
Filed: 1933-08-29
Abstract: 1-(3<1> : 4<1> : 5<1>-Trialkoxyphenyl)-6 : 7-dialkoxyisoquinolines are prepared by ring closure from N - (b  - methoxy)(b  - 3<1> : 4<1> - dialkoxyphenyl) ethyl-3 : 4 : 5-trialkoxybenzamides.  The reaction is effected by treating a boiling solution of the amide in an inert solvent with an acid condensing agent in not more than twice the amount required to combine with the water liberated in the reaction. Suitable acid condensing agents are phosphorus oxychloride, thionyl chloride, and silicon tetrachloride; the inert solvent may be benzene, toluene, carbon tetrachloride, or chloroform.  Examples are given of the preparation of 1-(3<1> : 4<1> : 5<1>-trimethoxyphenyl) - 6 : 7 - dimethoxyisoquinoline and 1 - (3<1> : 4<1> - 5<1> - triethoxyphenyl) - 6 : 7 dimethoxyisoquinoline.  The products are useful as substitutes for papaverine.  b  - (4 : 3 - Dimethoxyphenyl) - b  - methoxyethylamine, required for making the N-substituted trialkoxybenzamides used as starting materials in the examples, is prepared as follows.  3 : 4-Dimethoxybenzaldehyde is condensed with nitromethane to yield 3 : 4-dimethoxy-o -nitrostyrene, which is treated with methanol and sodium methylate to yield a -nitro-b -methoxy-b -(3 : 4-dimethoxyphenyl)ethane; the latter yields the required amine when reduced with coppered zinc dust in formic acid. The Specification as open to inspection under Sect. 91 includes an example of the preparation of 1-(3<1> : 4<1> : 5<1>-triethoxyphenyl)-6 : 7-methylene dioxyisoquinoline, and states that up to four times the theoretical quantity of condensing agent may be used.  This subject-matter does not appear in the Specification as accepted.

Abstract: 957,310. Moulding hollow articles. ILLINOIS TOOL WORKS Inc. July 11, 1960, No. 24128/60. Heading B5A. [Also in Divisions B6 and B8] A sheet 48 of polystyrene which may be direct from an extrusion machine and tensioned by spring-pressed rollers 50 is fed by clamps 58, Fig. 4, which grip the sheet during their forward movement by an eccentrically mounted wheel 66, to a position between platens 18, 28. During this movement the sheet is heated by a radiant heater 94. The platen 28 is then lowered to first clamp the sheet between a fixed part 152, Fig. 9, and a plate 156, and then after further lowering of the platen, a plunger 50 stretches the sheet and shears off the sheet between flanges 178, 180. Before the platen 28 completes its downward movement, the mould halves 118, 120 of the female mould are brought together by cams. The sheet is finally shaped by blowing air through passages 192. The flow of air is diffused by a fabric covering 194. After moulding, the lower platen is moved to the right (shown dotted in Fig. 1) and ejector pins 98 are raised between the separate halves of the female mould to lift the moulded articles, and simultaneously a blast of air from orifices 102 blows the articles on a conveyer (not shown).
