Title: Brake control apparatus for rail vehicles
IPC: B61H9/00
Filed: 1971-04-19
Abstract: 1328913 Fluid pressure systems for rail vehicles KNORR-BREMSE GmbH 19 April 1971 [2 April 1970] 26391/71 Headings F2E and F2F [Also in Division B7] A pressurized fluid brake system for a rail vehicle has a brake control valve 3 responsive to a drop in pressure in a train pipe 1 to cause introduction of an anticipatory braking pressure from an auxiliary reservoir 5 into a pipe conduit 6. The anticipatory braking pressure controls a pressure transmitter 7 but the transmitter 7 is also responsive to the pressure in a pipe conduit 13 which pressure is proportional to the vehicle loading, and the pressure transmitter 7 selectively transmits pressure to pipe conduits 9, 11 which are respectively connected to a no-load brake cylinder 10 and a load brake cylinder 12. With a constant anticipatory braking pressure the pressure transmitter 7 introduces into the pipe conduit 9, in the load range from zero-loading up to a predetermined medium loading L/2, pressurized fluid which rises from a minimum value P min  to a maximum value P max , but when the medium loading L/2 is reached the pressure transmitter 7 then lowers the pressure in the pipe conduit 9 to the value P min  and, with increased vehicle loading, starts to introduce into the pipe conduits 9 and 11 fluid at an increasing pressure which reaches the maximum value P max  at maximum vehicle loading L max . Thus up to medium loading only the no-load brake cylinder 10 has compressed air admitted to it, but when the medium loading is exceeded compressed air is also admitted to the load brake cylinder 12. The no-load cylinder 10 incorporates a piston 20 with a piston-rod 22 which is pivoted on a brake lever 23, and the piston 20 is movable to cause the lever 23 apply to a shoe 27 to a disc 29: a drawbar 24 connects the lever 23 to a lever 25 pivoted by means of a bearing block 26 on the cylinder 12 and actuating movement of the lever 23 causes a shoe 28 on lever 25 to be brought into contact with the disc 29. The cylinder 12 includes a piston 16 with a piston rod 17 which is provided with a plate 19 which is operable to move the piston 20. A pipe conduit 39 connects a cylinder 36 with the pipe conduit 6 and the anticipatory braking pressure in the pipe 6 acts on a piston 35 in the cylinder 36: the piston 35 has a piston rod 34 to which is attached a cleaning block 33 and this cleaning block 33 is movable into engagement with a tread 32 of a vehicle wheel 31. The cleaning block 33 cleans the tread 32 to improve wheelrail adhesion and also acts as a brake shoe, the braking action of which is dependent on the value of the anticipatory brake pressure but is independent of vehicle loading.

Abstract: 823,679. Coating wires by extrusion. ADOUART, L., and MATERIEL DE CABLIERIE, Aug. 21, 1957 [May 22, 1957], No. 26449/57. Class 87(2). [Also in Group IX] In an extrusion machine for coating wires with a multi-coloured helicallydisposed plastic covering the wire is fed to and received from the extruder by containers which rotate about the axis of the wire as it passes through the extruder. The wire is drawn from the centre of a spool contained in a rotating drum 10 by a capstan 14, is passed through the extrusion head 15 and the coated wire is then fed by a capstan 16 to the inside of a rotating drum 17 wherein it is coiled inwardly of the drum by a reciprocating tube 19. The receiving unit, Fig. 5, of the machine comprises the drum 17 on a hollow shaft 37, rotated by a grooved belt 41 from a shaft 24, the shaft 37 carrying a grooved pulley 47 which is rotated about its own axis by a wheel 50, worm 51 and a pinion 54 which revolves around a stationary pinion 55. The shaft 24 also, via a reduction gear 43, rotates a shaft 22 having a double thread which reciprocates the wire laying tube 19 by means of a bracket 20 and block 21. The feeding unit, Fig. 4 (not shown), is similar but has no wire laying unit. The out of balance forces created by the driving means for the capstans 14, 16 are countered by the provision of "dummy" parts 57, 58, 59, 60 as shown in Fig. 6. In operation the capstans move the wire through the extruder whilst rotation of the wires causes the extruded sheath to be helically applied.

Filed: 1945-10-13
Abstract: 602,283. Hydraulic machines. STORER, A., and STORER, J. A. Oct. 13, 1945, No. 26808. [Class 69 (ii)] A valve 16 controlling the admission of hydraulic pressure to a series of operational circuits 17 is actuated through a control member 20 susceptible to the variable pressures created by the resistance encountered in the operations, the arrangement of the valve mechanism being such that at the conclusion of each operation the variable pressure builds up and actuates the control member, which in turn effects the actuation of the valve mechanism to close the hydraulic circuit pertaining to the operation which has been completed and to open the circuit pertaining to the next operation in the sequence to be performed. Liquid from the inlet 11 flows through the orifice 12 into the chamber 13, through the stem 15 of the rotary valve 16 controlling the feed ports to the circuits 17. Liquid also flows through passage 18 into cylinder 19 to urge piston 20 downwards. At the end of the working operation pressure builds up in the chamber 13, forces piston 20 upwards until the passages 18 and 23 are connected through the ports 22a, 22 and 22b. Liquid enters cylinder 24, forces operating piston 25 downwards causing the rack 26 to engage teeth 27 which rotate the valve 16 to close the circuit relating to the finished operation and open that relating to the next. Resultant drop in pressure in the chamber 13 permits piston 20 to descend and open the passage 23 to the exhaust 33. Liquid from passage 31 raises piston 25, but due to a ratchet mechanism in 27, does not rotate the valve 16. The process is then repeated for the new operation.
