Title: Synthetic resinous materials and process of making same
IPC: B01J39/18
Filed: 1944-11-20
Abstract: Thermosetting resinous products containing salt-forming sulphonate groups are formed by heating at a pH of 4-10, one or more of formaldehyde, acetaldehyde, butyraldehyde, furfuraldehyde and benzaldehyde, together with a water-soluble metal salt of sulphurous acid and a carbamide, a polyaminodiazine or a polyamino triazine or mixtures thereof, at least two amino groups of which are primary, 0.5-2.0 mols. of aldehyde being used per reactive amino group and the salt yielding 0.05-0.4 mol. of bisulphite per mol. of aldehyde.  The term carbamide includes urea and its derivatives, thiourea, dicyandiamide, guanidine or mixtures thereof.  Amino - azines specified are 2,6-diamino - 1,3 - diazine; 5 - methyl - 2,6 - diamino - 1,3-diazine; 4-chloro-2,6-diamino-1,3-diazine; polyamino pyrimidines; melamine; melam; ammeline; thioammeline; b  - b 1 - bis - thio - ammeline diethyl ether and similar compounds as described in Specification 543,256.  Sulphenous acid salts of the alkali metals are particularly useful.  The aldehyde and amino compound may be reacted together first and the product reacted with the sulphite, or the aldehyde and sulphite may be reacted first and the product reacted with the amino body or all three reactants may be mixed together at the outset.  The preferred temperature range is from 60 DEG  C. to the boiling point of the mixture.  The product may be concentrated or dried, e.g. by heating with or without vacuum, drum-drying or spray-drying.  Examples describe the preparation of resins from (1) urea and formaldehyde in presence of sodium metabisulphite; (2) melamine and formaldehyde in presence of sodium sulphite; (3) urea and acetaldehyde in presence of sodium metabisulphite; (4) melamine, urea and formaldehyde in presence of sodium sulphite.  All the products were water-soluble. They are suitable for making films, for treating textiles, for addition to paper pulp in the beater to make paper of high wet strength, for impregnating fibrous materials such as paper, cloth or wood.  They may be used as ion exchange resins, for casting or laminating, if desired in conjunction with plasticisers, pigments, fillers, starch, cereal or wood flour.  The metal attached to the sulphonate group may be replaced by another metal, e.g. a heavy metal.  Thus, cloth or wood may be impregnated with a solution of a resin containing a sodium sulphonate group and then treated with a solution of a salt, e.g. copper sulphate, to exchange the sodium atoms for copper (see Group VIII).  Specifications 595,367, [Group VIII], and 595,368 are referred to.

Abstract: 1,035,349. Lasers. WESTERN ELECTRICAL CO. Inc. June 11, 1963 [June 21, 1962], No. 23134/63. Heading H3B. A helium-neon maser emits visible radiation having a wavelength of substantially 6328 Angstroms corresponding to the 3s 2 -2p 4  transition in neon. As shown in Fig. 1 a quartz tube 11 contains a 10-1 helium neon mixture at a pressure of about 0À7 millimetres of mercury, the tube having gas discharge established by a potential of 1700 v. applied between a thoriated tungsten cathode 17 and a cylindrical molybdenum anode 18 provided in pockets 15. A light beam path through the tube is defined by transparent windows 12, 13 which are inclined at Brewster's angle so that light is polarized in the plane of incidence and transmitted without reflection. Adjacent to the windows are positioned plano-concave spherical dielectric layer reflectors 19, 20 having a peak reflectivity at about 6340 Angstroms. The number of modes which the optical cavity so formed will support is reduced by positioning light interrupting elements in the form of an adjustable iris 23 and crossed wires 24, 25, Fig. 2, at the nulls of the modes supported. The cross wires are mounted in an assembly 22 consisting of independently rotatable aligned cylinders 22A, 22B each carrying a respective wire, a partially reflective element as described in Specification 1,015,154 may be included in the light path.

Aug. 24, 1932, No. 23727. Convention date, May 9. [Classes 83 (ii) and 83 (iv).] Dividing.-Metal trays or shelving having a series of parallel slots therein are produced by stamping and severing a metal sheet to form two or more sections each having a series of parallel bars extending from one side, and uniting the bars of two of said sections end to end. A metal sheet 32, Fig. 5, is formed with a continuous groove 33 and a plurality of depressions 37 shaped as shown by Fig. 2, which is an enlarged sectional view of Fig. 5. The sheet 32 is then severed along the dot and dash lines 40 and is subsequently bent along the dotted lines 41 to form two groups of sections 44, 45, as shown in Fig. 6, each of the sections 44 being then welded to its opposite section 45, so that two completed trays are formed. A single tray may be fashioned from a metal sheet 32 by dispensing with the depressions 37 and severing the blank along the centre line of the groove 33 to produce two opposed sections such as 45, which can be welded together to form a single tray. According to a modification, the intermediate bars of the tray may be made tubular in section by forming wider groove portions 33 so that when the plate is severed the combined width of the flanges on each side of the transverse 'bars will be sufficient to allow the formation of a tubular cross section by bending the flanges.

The base is completed afloat by further casting concrete and then frusto portions 9, 10 of the support columns P and frusto conical portion 12 and upper portion 11 of the further columns A are built onto the floating base 1. The further columns A are sealed at their upper ends and carry floatation collars 19. The deck 2 is built in a dry dock and has upper portions 18 of the support columns P subsequently fixed temporarily in passages 14. The base 1 is submerged and the deck 2 is located above it so that the support column portions 10, 18 can be permanently connected together. The deck 2 is moved relative to the column portions 18 by either submerging the base 1 further or raising the deck 2 and, when in the desired position, it is then permanently connected to the columns P.

Filed: 1920-08-18
Abstract: 150,286. Cramer, S. S. Aug. 21, 1919, [Convention date]. Exhausting air; expressioncontrolling.-A pneumaticallyoperated piano-player is connected to the casing of a centrifugal pump driven by an electric motor; a spring-controlled valve for relieving the vacuum is secured to the casing, and is set at its minimum limit to permit air to enter to cool the motor; it may be moved by hand to permit air to enter at varying rates. The casing is constructed to minimize the sound escaping. The casing is made in two parts 1, 4, Fig. 1, and the inner surface of the sections 6. 7 are covered with fibrous material 9, with apertures 10 registering with apertures 8 in part 7 of the casing. A baffle-plate 11 with sound-insulating walls is secured on the outside of the casing bottom. A pipe 91 from the piano mechanism conveys air to a large aperture 90 in the casing, and the opening is screened by a mesh section 94, Air is also admitted through apertures 98 which may be opened to varying degrees by means of a cover disk 100 with a similar series of apertures and which can be rotated on a spindle 101. The disc has an operating-arm 102 movable between limit screws 106, and held by a spring 109 in a predetermined position to permit air to enter to cool the motor under any conditions, The disc 100 may be adjusted to allow a high pressure in the piano mechanism to produce sounds of low intensity or to produce loud crash music. The complete arrangement may be supported on flexible supports inside or outside the piano.
