Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/30
Filed: 1931-08-05
Abstract: 387,383. Fluid - pressure brakes. WESTINGHOUSE BRAKE & SAXBY SIGNAL CO., Ltd., 82, York Road, King's Cross, London.-(Assignees of Farmer, C. C. ; 7008, Thomas Boulevard, Pittsburg, U.S.A.) Aug. 5, 1931, No. 22189. Convention date, Aug. 6, 1930. [Class 103 (i).] In a triple valve on brake application, venting of the train pipe is effected by the movement of the graduating valve before the main valve is moved and the movement of the main valve effects a further venting of the train pipe. The fluid from the train pipe is vented to chambers one of which is vented to atmosphere in lay position. A retaining valve can be operated to retain a certain degree of pressure in the brake cylinder and certain of the venting chambers. The initial movement of the triple valve piston 7 on brake application closes the feed passage 33 for the auxiliary reservoir 4 and a spring plunger 16 on the triple valve stem 11 engages a flange 14 on the main valve. Further reduction of train-pipe pressure compresses the flanged spring 13 and moves the graduating valve 10 to connect the train pipe to a venting chamber 58 by a cavity 39 and passages 46, 45, 44, 37, 36. The graduating and main valves are then moved together to connect the auxiliary reservoir to the brake cylinder by passages 49, 48, 34, to cut off the chamber 58 from the train pipe and to connect the train pipe to venting chambers 59, 60 by passages 46, 50, 51 and 46, 54, 53, 52, 41 respectively to produce further venting of the train pipe. Restrictions in the passages to chambers 59, 60 shows the venting and ensures that it is proportional to the time the triple valve is in service position. When auxiliary reservoir pressure is slightly below train-pipe pressure the graduating valve moves to lap position in which brake cylinder supply is cut off and the third venting chamber 60 is vented to the atmosphere through passages 41, 52, 53, 55, 56. The restriction in the passage 41 shows this venting so that the amount of venting depends on the time the triple valve is in the lap position. When the brakes are released the valve takes up the position, shown in the Figure in which the brake cylinder and chamber 58 are connected to atmosphere through passage 20 and the retaining valve 51 the chamber 59 through non-return valve 32 and a valve 27 to the chamber 58 and the chamber 60 to an atmospheric opening 40. When the valve 5 is operated by a handle 19 to retain a certain degree of pressure in the brake cylinder fluid pressure is also retained in chamber 58 and this pressure acts on a diaphragm 22 to hold closed the valve 27 and thus retain fluid pressure in the chamber 59. Thus upon a successive brake, application fluid will not be vented to the chamber 59 and flow to the first chamber will be reduced, thus preventing an excessive reapplication of the brakes. A ball valve 57 prevents back flow from the chamber 59 to the train pipe. A spring 18 or spring 13 move the piston from the usual packing ring on brake release to expose the full area of the piston 7 to train-pipe pressure.

Title: Improvements in or relating to the extraction of metal values
Inventor: FLETCHER ARCHIBALD WILLIAM
IPC: C22B60/02
Filed: 1959-06-29
Abstract: Metal values are extracted from an aqueous medium containing the value in solution or suspension by contacting with a solution of naphthenic acid in an inert organic solvent immiscible with the aqueous medium.  The aqueous medium is at a pH not more than 0,5 below the hydrolysis pH of the metal to be extracted. Preferential extraction from a mixture of two metal values may also be made by choosing the appropriate hydrolysis pH value. Solvents such as benzene, toluene, xylene, white spirit or preferably kerosene may be used and the metal values are stripped by acidification with dilute mineral acids, e.g. sulphuric acid. Co-current and counter-current processes are used and examples describe the separation of copper, copper and iron, copper and cobalt, and copper and nickel.ALSO:Naphthenates of metals, e.g. copper, cobalt, nickel, iron, zinc, manganese and calcium, are used in a process for the extraction of metal values from an aqueous medium containing the value in solution or suspension.  The values are contacted with a solution of naphthenic acid in an inert organic solvent such as benzene, toluene, xylene, white spirit and preferably kerosene. The metals are stripped from the resulting solution by acidification with dilute mineral acids.  Examples describe the separation of copper, copper and iron, copper and cobalt, and copper and nickel.

Title: Improvements in the decortication of ramie and other textile stalks or leaves
IPC: D01B1/22
Filed: 1939-08-01
Abstract: 545,727. Decorticating ramie &c. FAURE, A. Aug. 1, 1939, No. 22283. Convention date, Aug. 19, 1938. [Class 120 (i)] Ramie and other textile stalks or leaves are decorticated by subjecting the stalk to an operation for removing the woody material and then to an operation for removing the pellicle, the strips obtained by the removal of the woody material being, in the second operation, carried continuously forward and subjected to rapid intermittent elastic compression during such movement. As shown a rotating beater 1 is mounted on a horizontal shaft 3 and operates in conjunction with a series of longitudinally arranged bars 5 to remove the woody material from the stalks 20 which are carried through the apparatus by a pulley 15 and cable 19 co-operating therewith. The stalks are disposed vertically between the pulley and cable and the entrance ends of the blades 2 of the beater and of the bars 5 are curved, the bars extending around about a quarter of the circumference of the beater, covering about half the width thereof and projecting a substantial length beyond the beater. A resilient counter thrasher, with which the beater co-operates to remove the pellicle, is disposed opposite the width of the beater not occupied by the bars 5 and consists of a shoe 8 supported by springs 13 against a support 12, the underneath portion of the shoe being provided with a recess forming a longitudinal edge 10; the removal of the pellicle is considerably facilitated by the rapidly recurring vibration set up in the shoe 8 while the strips are carried forward by the pulley and cable in a direction opposite to that which the beater tends to impart to them. The upper untreated parts of the stalks may be treated in another machine or a pair of pulleys rotating in opposite directions and cables may be arranged at different levels in connection with two machines so that as the stalks from the first machine are taken by the second pulley cable the untreated upper parts of the stalks fall down and hang below the pulley for treatment in the second machine.

Working-fluid supply.-The internal-combustion turbine described in the parent Specification is provided with two or other number of combustion chambers and compressors and the nozzles are modified to act as injectors to cause cooling-air to mix with the gases before reaching the turbine. The compressor valve gear is also modified as the compressors are arranged to give two strokes per revolution of the shaft. A suction valve g with its seating on the compressor release valve h opens against a spring g<1> on the suction stroke, the gas passing through the inlet S and a registering port formed in the release valve cap h<2>. On the compression stroke, the gas is delivered to the combustion chamber by the release valve h lifting against the spring h<1>. The nozzles are formed in two sections, a parallel portion l and a diverging portion l<1> through which air is delivered from the chamber n by injector action. A valve o in the chamber n acts as a muffle. Two compressors give two simultaneous impulses at points 180‹ apart; three compressors give these simultaneous impulses at 120‹ apart. The cam may operate more than one compressor, e.g. three cams may each operate four compressors which would give four successive triple im. pulses.

Abstract: 387,254. Type-bar-maldng machines. INTERTYPE CORPORATION, 360, Furman Street, Brooklyn, New York, U.S.A. Aug. 12, 1932, No. 22653. Convention date, May 19. [Class 100 (iii).] Clamping matrices.-Quadding-mechanism of the kind described in Specification 388,993 is modified so as to enable lines to be quadded, when required, at the left-hand end only, as well as quadded at the right-hand end or centralized. Jaw-closing mechanism similar to that described in the prior Specification is provided, and comprises a lever 8, Fig. 3, pivotally mounted on the machine frame, and adapted to be rocked by a cam acting through a spring 16. The lever 8 is pivotally connected to a rack-bar 5, normally connected to the right-hand jaw 3. The lefthand jaw 2 is provided with a rack-bar 4, Fig. 1, which can be connected to the bar 5, so as to effect a movement of both jaws, by an axiallymovable pinion 20, operated by means of a knob 23. The rack-bar 5 and the jaw 3 are normally held in retracted or full-line receiving position by a latch 18a, which is tripped by the first elevator in its descent. When moved into contact with the matrices, the jaws are locked by a toothed pawl 36, adapted to engage teeth on the underside of the rack-bar 5, and pivotally mounted on a lever 24, which is rocked by a roller 52 on the justification-bar 51 during its ascent. The rocking of the lever 24 first disengages the pawl 36 from a fixed stop 42, whereupon the pawl is raised by a spring into engagement with the rack-bar 5. The further movement of the lever 24 forces the pawl and the rack-bar to the right, so as to lock the line. Means are provided for leaving a variable amount of unfilled space in the line, in the case of lines which are set nearly of full length, before the pawl 36 engages the rack-bar 5. These comprise a pawl 76, pivoted on the rack-bar, and adapted to intervene between a projection 40a on the pawl 36 and a stop-pin 81, when the rack-bar is in retracted position. The stop-pin 81 is mounted in a rotatable member 80, so that the distance through which the rack-bar moves, before it is engaged by the pawl 36, can be varied. The pawl 36 is also controlled by a lever 53, which is operated by a pin 57 on the left-hand viceclosing device, which is operated from a cam through a rod 58 in known manner. The lever 53 serves to depress the pawl 36 slightly, so as to relax the locking pressure on the line, in order to permit of the alignment of the matrices between the first and the second justification. The full descent of the rod 58 retracts the pawl from the rack-bar 5, to permit of its return to initial position. When lines are to be quadded at the left-hand end only, the right-hand jaw 3 is disconnected from the rack-bar 5 by movement of a sliding pin 150, operated by a handlever 155, the movement of the pin also serving to lock the jaw to the vice-cap. The rackbars 4, 5 are then connected by means of the pinion 20, so that only the left-hand jaw 2 is operated by the closing mechanism.
