Abstract: 1487632 Flame-resistant thermosetting resin compositions SUMITOMO BAKELITE CO Ltd 10 Sept 1974 [11 Sept 1973 (2) 14 Jan 1974 20 Feb 1974 (2)] 14821/77 Divided out of 1487631 Headings C3R and C3B [Also in Divisions B5 and C2]  A flame-resistant thermosetting resin composition is derived from a thermosetting resin selected from phenolic resins, epoxy resins, these resins modified with one another, and these resins modified with amino resins and at least one phosphorus compound of the general formula where R 8  and R 9  represent alkyl, alkenyl or aryl groups of up to 20 carbon atoms and may be halo-substituted, R 7  represents an alkylene, alkenylene or arylene group having up to 10 carbon atoms and may be halo-substituted, and X represents a hydrogen atom or hydroxymethyl group. Suitable amino resins are those made from urea, thiourea, melamine, benzoguanamine, acetoguanamine, formguanamine or dicyandiamide and formaldehyde. The phenolic resin may be a phenolformaldehyde resin optionally modified with a drying oil, rubber or aromatic hydrocarbon. The phosphorus compound may be added at any stage of or after production of the resin but usually prior to curing the resin. The resin composition may be further admixed with conventional flame-retardants. In Example 2 phenol, aqueous HCHO and N-hydroxymethyl-3-(diphenylphosphono)propionamide are reacted together in the presence of HCl and the resulting novolac resin is used in the preparation of a particulate moulding material comprising the novolac resin, wood flour, hexamethylenetetramine, magnesia and magnesium stearate. In Examples 3 and 6 a phenolic resin is prepared by reacting phenol, aqueous HCHO, 3-(diphenylphosphono)propionamide and optionally melamine in the presence of aqueous NH 3 . In Example 7 a phenol-formaldehyde resin is first prepared and is then mixed with N- hydroxymethyl - 3 - (diethylphosphono)propionamide. In Example 8 a cresol-formaldehyde resin is reacted with the reaction product of 3 - (diethylphosphono)propionamide and formaldehyde. In Example 9 a phenol-formaldehyde resin is reacted with a benzoguanamine - formaldehyde resin and the product mixed with N-hydroxymethyl-3-(diethylphosphono) propionamide. In Example 10 a resin prepared from cresol, acetoguanamine and aqueous HCHO in the presence of aqueous NH 3  is mixed with N-hydroxymethyl-3-(diethylphosphono)propionamide. In Example 11 a resin prepared from acetoguanamine, 3-(diphenylphosphono)propionamide and aqueous HCHO is mixed with a conventional phenolic resole resin. In Example 12 a benzoguanamine- HCHO resin is mixed with the reaction product of 3 - (diphenylphosphono)propionamide and formaldehyde and with a conventional phenolic resole resin. The resin compositions of Examples 3-12 in organic solvents are used as adhesives in the preparation of Kraft paper laminates, which are cured by heating under pressure.

Title: Improvements in and relating to lubricating compositions
IPC: C10M169/00
Filed: 1951-06-22
Abstract: A lubricating composition comprises a major proportion of a lubricating oil, thickened by a synthetic inorganic gelling agent which is an inorganic compound containing an alkaline earth metal and silicon or is a mixture of an inorganic compound of an alkaline earth metal and an inorganic compound of silicon.  The inorganic compound contains between 2 and 25 per cent. by weight of the alkaline earth metal.  Compounds mentioned are alkaline earth (i.e. Be, Mg, Ca, Sr and Ba) silicates with or without silica or alkaline earth metal oxides or hydroxides, mixtures of silica with alkaline earth metal oxides or hydroxides, synthetic zeolites and synthetic montmorillonites.  A water-repelling agent which may be a cationic, anionic or non-ionic surface active agent may be included in the compositions.  Surface-active agents mentioned are quaternary ammonium salts, amine salts of organic or inorganic acids, ammonia or amine condensation products, higher fatty acids, phosphonic and phosphinic acids, dicarboxylic acids, amino acids, sulphonic acids, naphthenic acids and these acids which have been chlorinated, sulphurised or phosphorised; esters of fatty and hydroxy fatty acids, monohydric and polyhydric alcohols, ethers of polyhydric alcohols, mercapto compounds and polyvalent metal salts of high molecular weight organic acids; many examples of these classes of compounds are given.  The cationic surface-active agents may be treated with phosphorus; sulphur- or silicon-containing oxy-acids.  The lubricating oil may be a mineral oil or a synthetic oil such as oxyalkylene polymers, silicone fluids, organic phosphates, polymerized olefins and esters, examples of which are given.  The gels containing alkaline earth metal compounds may be improved by reaction with alkali metal hydroxide fluorides or silicates or with alkali metal monohydrogen phosphates.  Various methods for the preparation of the greases are described.  In one example, a magnesium silicate gel is dried to form a xerogel which is heated with potassium hydroxide at 250 DEG  C. for 48 hours.  The product is washed, dispersed in water and treated with 60 per cent. by weight of dimethyldiheptadecylammonium chloride.  The aminogel thus formed is dispersed in mineral lubricating oil, water eliminated and the composition milled to form a grease.  Specifications 697,670 and 706,772 are referred to.

Abstract: 810,409. Indicating the position of marked articles. STANDARD TELEPHONES & CABLES Ltd. May 17, 1957 [May 24, 1956], No. 15791/57. Class 40 (3). In apparatus for detecting whether a letter or other object is in a normal or inverted position, n photo-electric cells, each sensitive to a different colour, obtain signals from two different positions on the letter in either one of which positions a postage stamp or other mark may occur and from a third position at which the postage stamp will not occur, and two n-phase and neutral circuits are provided, each corresponding to a separate one of the first two positions, the phases of which are energized in proportion to the signals due to the separate colours derived by the photo-cells from the first two positions on the letter divided by the signals due to the corresponding colours derived by the photo-cells from the third position, the currents in the two neutral conductors being compared to provide an indication of the position of a stamp on the letter. Three areas F1, F2, F3 of a letter 1, Fig. 2, are successively illuminated by a light source and reflected light from these areas falls upon photo-electric receivers Er, Eg, Eb, Fig. 4, sensitive respectively to red, green and blue light. The voltages due to each colour from each area are applied to respective storage condensers Cr1-Cb3 via a switch 3. Each phase of a three-phase voltage source 4 is connected to respective dividing devices Dr, Dg, Db which are connected respectively to the condensers Cr2, Cg2, Cb2 so that each dividing device has an output proportional to the reciprocal of a respective one of the colour signal voltages derived from the area F2. The output of the dividing device Dr is applied to multiplying devices Mr1, Mr3 where it is multiplied by the red signal voltages stored on condensers Cr1, Cr3 derived from the areas F1, F3. Similarly the outputs of the dividing devices Dg, Db are applied to multiplying devices Mg1, Mg3, Mb1 Mb3 and there multiplied by corresponding colour signal voltages derived from the areas F1, F3. The outputs of the multiplying devices Mr1, Mg1, Mb1 are connected to equal resistances 5 of a three-phase and neutral system 6 and the outputs of the multiplying devices Mr3, Mg3, Mb3 are connected to equal 5 resistances of a three-phase and neutral system 7, in which the vectoral additions of the voltage outputs of each group of multiplying devices are represented by the neutral currents of the three-phase systems 6 and 7. By comparing the two neutral currents of the systems 6 and 7 by means of a polarized relay 10, an indication is given as to whether a stamp is in the area F1 or F3.
