Title: Arrangement on railway vehicles for guiding bogies or single axles
IPC: B61F5/38
Filed: 1935-07-11
Abstract: 437,181. Railway-vehicle undercarriages. HUGUENIN, A., 319, Hardstrasse, Zurich, Switzerland. July 11, 1935, No. 19828. Convention date, July 12, 1934. [Class 103 (vi)] In an arrangement for positively effecting radiation of the axles ofarailway-vehicle truck or bogie by means of feelers engaging the track coacting with a hydraulic servomotor for displacing the axles, the control valve 13, Fig. 5, of the servomotor is incorporated in the servomotor piston, and the valve edges 16, 17 that obstruct the flow of fluid are so disposed in relation to the passages that the latter may be given a large cross-section, occupying the entire cross-section of the bored members except for the necessary thickness of the walls and reinforcing bridge-pieces. Oil is delivered under pressure by a pump 21 to a chamber 25 within the servomotor casing 14, which is secured to the vehicle frame. In the normal or central position shown a continuous flow of oil is maintained through passages 26 in the piston 15, past the valve edge 17 to an annular chamber 27, thence past the valve edge 16 to a second chamber 28, and then through a bore 29 in the valve via an orifice 30 to a duct 31 back to the supply reservoir. The annular chamber 27 is also connected by a passage 32 to a chamber 33 within the casing 14. Should the valve 13 be displaced, say, to the right, the flow of fluid is obstructed at the edge 17, pressure rises in the chamber 25 and the piston 15 immediately moves to the right also, the fluid in the chamber 33 being ejected by the passage 32, annular chamber 27 and bore 29. Similarly, if the valve 13 moves to the left, the flow is obstructed at the edge 16, pressure accumulates in chamber 33 and the piston follows to the left. Movement of the valve 13 in either direction is effected by a lever 11 mounted on a shaft 12 and connected by a rod 10, Fig. 2, to a lever 9 on a rock-shaft 7, which in turn is displaced by movement of the feeler-wheel 1 through a rotatable shaft 3 and lever 6 with an interposed flexible element 8<1> in the form of a dashpot. The displacements of the piston 15 are communicated to the bogie or axle frame 18, Fig. 4, by a ball-and-socket connection 20 between the piston and a projection 19 on the frame 18.

Title: Method of impregnating fabrics and similar articles
IPC: D06P1/44
Filed: 1946-07-15
Abstract: A method for imparting a permanent colour to cellulosic fibrous materials such as fabrics, comprises immersion for a short length of time in cuprammonium solution in which is disposed a finely-divided coloured solid substance and a dispersing agent, the solution dissolving the surface of the fabric, and the time of immersion being such that the inner part of the fibres is not attacked, and then drying, the finely-divided solid substance being permanently incorporated in the fabric.  The materials to be treated may be spun or woven fibres, paper, cardboard, wood, straw, raffia, grass, ropetwine, cellulose and regenerated cellulose.  The particles to be incorporated should be of particle size up to 5 microns.  They may be particles of lamp-black, carbon black, zinc, arsenic or antimony compounds, fast-to-light pigments such as copper phthalocyanine or chromium oxide.  There may also be present fireproofing substances such as chlorinated rubber or paraffin, or substances having toxic effects on micro-organisms, such as copper oxide.  Mixtures of two or more substances may be used as, for instance, in making a fireproof fabric toxic to mildew.  Suitable dispersing agents may be sodium lignin sulphonate or ethyl cellulose.  The solvent may be removed from the material after treatment by any known method, such as neutralization with acids or alkalis, washing out with water, evaporation or the like.  In examples, 30 lbs. of a fine particle size carbon black dispersion in sodium lignin sulphonate is added to 1000 gallons of cuprammonium solution containing 14 lbs. metallic copper per 100 gallons of 10 per cent ammonia.  About 1200 yards of 30 inch cotton cloth are immersed for about 90 seconds in the solution, passed through squeeze rolls and dried. To produce a fungicide dispersion, 30 lbs. of copper oxide are used in place of carbon black, and to produce a coloured fireproof fabric chlorinated rubber is used in addition to the carbon black. Specifications 6123/06, [Class 140], 25245/11, [Class 42 (i)], and 338,654, [Class 15 (ii)], are referred to.
