Title: Oil throwers for roller bearing axleboxes and the like
IPC: F16C33/80
Filed: 1939-04-21
Abstract: 527,811. Oil throwers for axle boxes. COLLINS, A. F., and LONDON PASSENGER TRANSPORT BOARD. April 21, 1939, No. 11987. [Class 122 (v)] An oil-throwing ring for roller-bearing and like axle-boxes is made from non-metallic material which wears rapidly on rubbing to limit the frictional generation of heat. The non-metallic material is preferably selflubricating with a low coefficient of friction, especially when dry and at rising temperatures. The thrower may be produced by winding on a former fibrous material such as cotton yarn, cloth, or paper, impregnated with a binder such as phenolic formaldehyde condensation product or other artificial resin, the final shaping being obtained by machining, or by pressing or moulding, with or without heat. In the form shown, the thrower has a cylindrical inner surface 11 which is rounded at 13, and a cylindrical outer surface 15 which is formed with V-shaped grooves 16 and semi-circular grooves 17. The co-operating surface of the flange 22 is formed with semi-circular grooves 23, but either the outer surface 15 or the surface of the flange 22 may be left plain. The thrower may extend beyond the shoulder 18 of the axle 19 to co-operate with an additional upper flange 24 on the axle-box 21.

Title: Production of coloured masses and articles of nylon
IPC: C08J3/22
Filed: 1943-07-26
Abstract: Coloured polyamide masses are produced by incorporating with molten nylon a dispersion of a pigment in a linear polyester or polyesteramide and then cooling.  The mass may be formed to shape before, during or after cooling.  Suitable linear polyesters may be obtained from dibasic organic acids and glycols or esterforming derivatives of these, e.g. ethylene glycol and adipic acid.  Suitable polyesteramides are described in Specifications 561,104 and 561,108. Polyesters or polyesteramides which have been modified with a diisocyanate as described in Specification 553,733 may also be used, provided that they are still fusible.  Suitable pigments are titanium dioxide, carbon black, copper phthalocyanine pigments, cadmium yellows, lead chromates, iron oxides, chromium oxides, ultramarine. Extenders such as blanc fixe, lithopone or zinc oxide, may also be used. The pigment may be stirred into the molten polyester or polyester-amide or may be worked into the solid material in a mixer. The dispersion may be stirred into the molten nylon and the melt cooled or particles of nylon may be coated with the dispersion and then melted and cooled.  Volatile organic liquids may be used to facilitate the application of the dispersions as coatings.  In examples: (1) Monastral Fast Blue B and a polyester-amide from adipic acid, ethylene glycol and monoethanolamine are mixed in an internal mixer.  The dispersion is diluted with an ethanol-water mixture to a smooth paste, which is agitated with chips of poly-hexamethylene adipamide to coat them.  The coated chips melt to a uniformily coloured blue mass which may be melt spun to fibres which may be cold drawn.  (2) A reddish-brown melt which may be extruded or spun to shape is formed as in example (1), using iron oxide pigment in place of Monastral Blue.  (3) Similar to examples (1) and (2), but employs Cadmium Red as the pigment.

Filed: 1935-04-23
Abstract: 453,612. Columns; reinforced concrete. BAUER, B., 51, Mariahilferstrasse, Vienna. April 23, 1935, No. 12261. [Class 20 (iv)] A reinforcement for a reinforced-concrete column comprises one or more profile irons and a lateral reinforcement consisting of a hooping in the form either of a helix of wire, strip or the like or of a plurality of disconnected and superimposed rings, such hooping being arranged either inside an area partly enclosed by the profile iron or irons and in contact with the latter, or around the outside of the profile iron or irons in such a way that a substantial length of each turn of the helical hooping or of each ring is in contact with at least two flanges of the profile iron or of each of the profile irons, so that in each case, part of the radial stress exerted by the concrete is taken by the profile iron or irons. As shown in Fig. 1, an I-section bar 1 is provided with a wire hooping 2 which lies against the flanges of the bar 1 and encloses the open sides in the form of a curve. A joist 7 is fixed directly to the bar 1 and, in order to secure continuity of the hooping 2, a plate 6 of semicircular cross-section is welded at the place where the joist 7 and bar 1 are connected. The hooping 2 may be welded to the bar 1. The joist 7 may, alternatively and as shown in Fig. 3, be connected to the bar 1 by channel irons 8 which also act as binding plates. The hooping may also be in the form of helical reinforcements 15 fitted in the open sides of an I-section bar 1 as shown in Fig. 4, and the outer concrete shell is protected by bent plates 17 welded to the section 1 or by a hooping which lies closely against the outer faces of the flanges of the section. In another construction, two channel bars 19 may be arranged as shown in Fig. 6 with a hooping 2 which lies closely against the flanges of the bars, and the outer layer of concrete may be held in position by a sheet metal plate 9. A helical reinforcement 21 may be stretched around a pair of channel bars 19, as shown in Fig. 8, or a single I-section bar 1, as shown in Fig. 10, the reinforcement being stretched across the open sides of the bars. Two channel bars 1, Fig. 12, may be arranged with an internal hooping 2, which may be spot welded to the bars 1. The two channel bars 1 may be replaced by four angle bars. In another form, helical coils of wire 24 may be placed in each of the open sides of two opposed channels 19 as shown in Fig. 16 and held in place by bands 25. Alternatively, coils may be similarly arranged in the open sides of a single profile iron of I-section.

Abstract: 1532898 Organopolysiloxane preservative compositions VERY IMPORTANT PRODUCTS Inc 26 March 1976 12266/76 Headings C3T and C3L [Also in Divisions D1 and B2] A preservative composition comprises an emulsion of at least one water emulsifiable organopolysiloxane fluid having a viscosity of 100 to 100,000 c.s. at ambient temperatures, and based on the weight of the polysiloxane fluid from 65 to 5000% wt. of water and from 15 to 65% wt. of at least two water-miscible polyols, the nature and relative ratios of the polyols being such that one polyol contributes most to improve adhesion of the other constituents to a treated surface and the other polyol contributes most to an improved appearance of the treated surface. The composition can be used for preserving and renewing surfaces, particularly natural and synthetic polymers, rubbers, wood, leather, metals and porcelain, by wetting the surface with the composition allowing the composition to penetrate the surface preferably for at least 24 hours, and repeating the wetting and penetration steps at least once. The organopolysiloxane fluid may be a trimethylsilyl-terminated polydimethyl siloxane which may be partially substituted with e.g. vinyl, trifluoropropyl and amino groups. Suitable polyols include glycerin, diethylene glycol, propylene glycols, butylene glycols, hexanetriol, dipropylene glycol, tetramethylene glycol, pentaerythritol, diepentene glycol, tetraethylene glycol, dimethylhexanediol, 2,2-dimethyl - 1,3, - butanediol, dimethyloldioxane, tetraethylene glycol, ethylene glycol, liquid polyethylene and polypropylene glycols, mannitol and sorbitol. A preferred composition comprises, as the polyol component, 0À5 to 10% wt. of diethylene glycol and 60 to 10% wt. of glycerin, based on the weight of the organopolysiloxane fluid. Optional ingredients include an emulsifier, e.g. nonylphenol, and a rust inhibitor, e.g. sodium nitrite or an organic phosphite. The compositions protect the surfaces against the effect of water, dirt, ozone,  ultraviolet rays, oxygen and the elements of smog. In the examples natural rubber and automobile tyres are treated as above.
