Abstract: 430,939. Pipe couplings. SHEVLIN, J. T., 15, South Street, Finsbury, London.- (Lubrication Corporation ; 910, South Michigan Avenue, Chicago, U.S.A.) April 14, 1934, No. 11343. [Class 99 (i)] [See also Group XXXIV] A lubrication fitting A has a shank B screwed into the member to be lubricated, and a head comprising a hemispherical surface D and an upper hemispherical surface E of smaller radius ; the surfaces D, E may be concentric or may be spaced apart by a cylindrical surface. A bore 2 extends through the fitting and communicates with the surface E through passages 3. The fitting may be engaged by a nozzle of the contact type or by a coupling member comprising a body 6 into which is screwed a nipple 17 connected to the lubricant supply. The body 6 has a cylindrical recess 7 to receive the head of the fitting A, and formed at its inner end with a surface G which makes fluid-tight contact with the surface E of the head ; a ball valve 14 is normally pressed by lubricant pressure to close the discharge passage of the coupling, but is lifted from its seat by the surface E when the coupling is placed on the fitting. A clamping member has cylindrical arms 8 guided in transverse passages 9 in the body 6 ; it is pressed in against spring pressure to bring cut-away portions 21 into alignment with the recess 7 to permit introduction of the fitting ; the clamp is then released and is held by the spring in clamping position. In a modification, Fig. 4, a plunger 25 is slidably mounted in the body 6<1>, being pressed by lubricant pressure against the surface E and serving to lift the ball valve 14.

Title: Improvements relating to the production of materials incorporating fibres or rod-like articles in substantially parallel mutual relation
Inventor: GORDON JAMES EDWARD
IPC: B29C48/95
Filed: 1949-04-29
Abstract: 673,367. Preparing fibres for spinning. MINISTER OF SUPPLY. July 31, 1950 [April 29, 1949], No. 11523/49. Classes 120(i) and 120(iii) [Also in Groups V and VIII] Sheet or strip material comprising fibres or similar small elongated rod-like elements which extend in the same general direction and in overlapping relationship one to another in the general plane of the material are made by impregnating a mass of fibres or similar elements with a liquid which acts as a lubricant and then, by compressing the mass against a surface whose general plane is substantially normal to the direction of applied pressure, extruding it in a direction normal to the direction of applied pressure through a duct which, in cross-section, is a narrow slot or slit shaped with its larger dimension substantially transversely of the direction of applied pressure and of the direction of extrusion. As shown, a plunger 12 compresses the mass 13 vertically within a hollow die 11 whence the mass escapes horizontally as a thin strip 16 through a duct 15 which is narrow vertically but broad horizontally. The fibres may be fragments split from asbestos ore or slivers of textile fibres. The lubricant may be water, or a viscous solution made by heating the fibres after they have been impregnated with a thin solution, or a material capable of setting or hardening, e.g. partly-polymerized phenol-formaldehyde condensation product. The lubricant may be allowed to stay in the mass after extrusion, in which case it may be allowed to set or harden or caused to do so, or may be removed after extrusion, in which case it may be a water-soluble lubricant. An extruded strip containing hardenable material as the lubricant may be pressed or shaped before and/or during hardening. The duct 15 may be heated. The extruded material may be taken away from the duct on an endless travelling openwork or continuous belt to drying or other means for the removal of the impregnant in the case of textile slivers intended for subsequent spinning.

April 17, 1934, No. 11569. [Class 37] Means for obtaining in a circuit 10 a D.C. voltage proportional to a D.C. voltage in a circuit 6 comprises a transformer 2 energized from an A.C. circuit 3 and connected through rectifiers 7 so as to supply current to the circuit 6. The transformer also supplies current through a tertiary winding 8 and rectifiers 9 to the circuit 10. Differences between the voltage of the A.C. source 3 and the D.C. circuit 6 are absorbed either in series reactances 4 or in the leakage reactance of the transformer so that its secondary terminal voltage remains equal to the voltage of the circuit 6 and the voltage of the tertiary winding which is closely coupled to the secondary remains proportional to the voltage of the circuit 6. In a modification, the tertiary winding 8 is omitted, the rectifiers 9 being connected directly to the terminals of the primary 1.
