Title: Fluid operated actuators
Inventor: KERENSKY GLEB
IPC: F15B21/00
Filed: 1969-04-11
Abstract: 1284734 Fluid operated actuators ENGLISH ELECTRIC CO Ltd 8 May 1970 [11 April 1969] 18818/69 Heading F1P A pneumatic or hydraulic pressure actuated piston and cylinder device 10, 11, Fig.1, having an output rod 13 is provided with means for supply fluid to by-pass the piston at a rate of flow below that of the supply e.g., a piston bore 15, means for closing the by-pass in one or other end positions of the piston e.g., annular plates 18, 19 at the cylinder ends and means responsive to rate of fluid-flow into or out of the cylinder for indicating in accordance to the rate of flow the position of the piston 10 relative to the two end positions. As shown the position indicator means comprises valves 25, 26 each containing a spring-biased piston 27 which control ports 34, 35 connected by ducts 33 to the return reservoir 21 or to the pump delivery line according to the setting of a selector valve 22. With valve 22 in the position shown piston 27 of valve 25 is at position A, Fig. 2, at the start of leftward movement of piston 10. The fluid discharged by piston 10 together with that passing through by-pass bore 15 displaces piston 27 of valve 25 into position D against a spring 31 and thus allows said discharged fluid to pass through cylinder ports 34, 35 and a duct 33 to the return reservoir 21. At completion of the leftward movement of piston 10 bore 15 is closed and flow into cylinder 28 of valve 25 ceases and fluid is exhausted from cylinder 28 by leftward movement of piston 27 under the action of the spring 31 until both ports 34, 35 are blocked by piston 27 in position B which thus indicates completion of stroke of piston 10. Position C of piston 27 of valve 25 indicates stalling of piston 10. Said valve piston 27 carries a rod 29 which operates position indicating means (not shown) and which rod serves to reset the piston 27 of valve 26 to the position shown in which it is subjected to equal and opposite fluid-pressure through ducts 32, 33. In a modification the indicator valves comprise a single piston (44), Fig. 3 (not shown) and in a further modification the indicator valve comprises a pivoted gravity-biased flap valve 50 Fig.7a located in a flow channel 51 inserted in either the supply or exhaust line of the actuator cylinder and having a part cylindrical lower surface 52 whereby fluid passes through the valve only after a relatively large displacement of the flap.

Title: Improved process of colouring cellulose esters
IPC: C08K5/23
Filed: 1936-07-09
Abstract: Coloured cellulose ester filaments, films and the like are obtained by incorporating diazo and coupling components into a solution of the ester, forming the solution into filaments, films, &c. and treating these with nitrous acid to produce the azo dyestuff in the material. Films so coloured include those produced by spraying the solution of the cellulose ester upon a textile fabric.  In an example, a dope made by dissolving cellulose acetate in a mixture of an acetone solution of o-aminoazotoluene with a solution in acetone and alcohol of the anilide of 2 : 3-hydroxynaphthoic acid, caustic soda and, if desired, a plasticizer such as triacetin, dimethyl or diethyl phthalate, is spun into filaments and the colour is developed by treating the dry filaments with an aqueous solution, preferably at 40-50 DEG  C. containing sodium nitrite and acetic acid. Alternatively, an organic nitrite, e.g. amyl nitrite, may be incorporated with the dope and the dried filaments exposed to an acid atmosphere, e.g. to acetic acid vapour.

Abstract: 403,148. Bolting. AUBIN, E., Elmstead, West Wittering, near Chichester, Sussex, and CLAREMONT, A. W., Vernon House, Sicilian Avenue, Bloomsbury Square, London. (Representatives of Royce, Sir F. H.) July 7, 1932, No. 19208. [Class 89 (i).] A method of securing together metal parts of engines which are subject to stress consists in dividing one of the parts at the end nearest to the other, locating the parts with reference to each other by locating means on either side of the division, and connecting the parts by means which act in or about the plane of the division to urge the parts together so that the divided portions of the divided part are urged apart so as to bear laterally on the locating moans. Fig. 1 shows the application of the method to the attachment of a balance weight b to a crank web a. The balance weight has a saw cut b<1> and two holes b<2>, b<3> at right angles. The hole b<3> provides for a narrow neck c<3> on the balance weight. Dowel pins d engage registering holes in the two parts a, b. The balance weight b is cut away at e so that the crank web reacts on it at points comparatively far removed and the spreading effect on tightening the nut c<1> is increased.

Title: Improved apparatus for the enlarging of rings
IPC: B21D53/44
Filed: 1925-07-29
Abstract: 238,536. Blois, F. Aug. 14, 1924, [Convention date]. Rolling annular bedies.- In a handcontrolled apparatus for enlarging jewellery rings by rolling, a planetary motion is given to one of the rollers by rotation of the operating handle. A vertical axle 6 secured by a nut 9 to a base 1, has keyed thereon a roll 4 and a pinion 10 and serves as an axis on which a lever 2 is rotated. The lever contains a support for a roll 5 and pinion 18, the portion 13 of the support engaging a square recess therein so that it may be axially adjusted without rotation. The adjustment is effected by a handle 3, which is screwed into the lever and engages the part 15 of the support 16, 16<a>. The position of the roll 5 and thus the amount of enlargement of the ring is indicated by a scale on the portion 20 of the handle which co-operates with an indicating line on the lever. The spindle 19 of the roll 5 is removable so that the roll may be replaced by others of different shapes. The ring is placed on the roll 4 and the lever rotated. The roll 5 is thus given a planetary motion by the pinions. The planetary motion may be effected by direct friction of the rolls. The rings may be inserted and removed without dismounting any part of the apparatus.

Filed: 1963-05-15
Abstract: 975,617. Door-operating appliances. A. TROUVAIN. May 15, 1963, No. 19343/63. Heading E2M. Two hinged doors, particularly for use in a mine, are interconnected so that when one door is opened it pulls the other open also, the arrangement being such that the doors move at substantially the same angular velocity as they start to open but at the end of the opening movement the one door has undergone a greater angular displacement than the other. The doors 1, 2 may be hinged to a central door post 3 and are interconnected by a cable 5 passing around a pulley 4, the angle through which the pulled door opens being dependent on the relative positions of the pulley, the hinge axes and the points at which the cable is secured to the doors. In the fully open position (Fig. 4) the air current flowing in the direction of the arrow 6 exerts a greater force on the pulled door 2 than on the door 1 so that both doors begin to close, complete closure of the doors being effected by a relatively weak spring or a small counterweight. Alternatively the closing may be assisted by mounting the doors on inclined axes or by providing inclined surfaces to lift the doors slightly as they open. Two cables may be employed one on each side of the doorway. The doors may be of unequal size.
