Title: Improvements in or relating to fluid-pressure actuators, more particularly for valves
IPC: F16K17/04
Filed: 1954-05-27
Abstract: 758,572. Fluid-actuated valves. GARRETT CORPORATION. May 27, 1954 [June 9, 1953], No. 15683/54. Class 135. A fluid - pressure operated actuator, e.g. for a valve, loaded by resilient means has associated with it a second pressure responsive part assisting the resilient means, and a metering valve operated by the actuator and controlling the pressure applied to the second pressure responsive member to compensate for the change in force exerted by the resilient means due to its deflection. As applied to a relief valve a closure member 15, Fig. 1, is loaded by a spring 26 assisted by fluid pressure in a space 24. The inlet to the space 24 is by way of a restriction 23 and the outlet is through a, metering valve 30 which is opened progressively as the relief valve opens. In a modification an actuator in the form of a flexible diaphragm 42, Fig. 3, loaded by a spring 43 has a universal coupling 55 with a compensating piston 45. Ports 57 in the piston are progressively uncovered as the diaphragm is moved against the spring by pressure admitted through a port 44. Thus, the pressure in a chamber below the piston, which has a restricted outlet 49, is increased so that the net downward pressure on the piston assisting the spring 43 is reduced. The actuator may be connected to a butterfly valve in a conduit and the port 44 to a point in the conduit downstream of the valve so that the valve acts as a pressure regulator. In a further modification a second diaphragm takes the place of the piston 45 and the metering valve is constituted by a movable sleeve coacting with a fixed cylindrical member with an axial, tapered groove.

Abstract: 989,020. Extruding tubular films. HERCULES POWDER CO. April 25, 1962 [April 28, 1961], No. 15845/62. Heading B5B. The mandrel of an apparatus for extruding a tubular film has an extension 5 for cooling the extruded film, the extension having a peripheral recess 7 supplied with cooling water via an inlet pipe 11, annular canal 12, and pipe 13. After effecting cooling, most of the water flows over an annular ridge 10 and is withdrawn via an annular canal 14, pipe 15, canal 16, and exit pipe 30. Water carried down by the film is absorbed by an annular sponge in a peripheral recess 18 and excess is withdrawn via canal 16 and pipe 20. Tight contact between the lower part of the extension and the film is maintained by applying suction at a peripheral recess 21 via a pipe 23. A pipe 24 supplies air for inflating the extruded film. Pipes 11, 20, 23 and 24 are housed in a bore 2 which is connected with peripheral recess 7 via a port 26. The film may be cooled externally as well as internally. The film may be heated by infrared rays just before inflation. The film may be of polypropylene or polyethylene terephthalate. An example of the extrusion of the latter is given. After inflation the film may be flattened (Fig. 3, not shown), split, and wound. Specifications 741,963 and 787,479 are referred to.

Title: Process for the production of a siliceous pigment
Inventor: LAGERSTROM GOSTA BERTIL
IPC: C09C1/30
Filed: 1960-05-05
Abstract: Pigmentary alkaline earth metal silicates are prepared by forming an aqueous solution from an alkali metal silicate, a free acid and a water soluble alkaline earth metal salt, e.g. by merging a stream of an aqueous solution of an alkali metal silicate with a stream of an aqueous solution of an acid and an alkaline earth metal salt, so that the mixed solution contains 0,6 to 1,4 moles of acid per mole of alkali metal silicate and at least sufficient alkaline earth metal salt to react with alkali metal silicate not reacted with the acid, immediately subjecting the mixed solutions to sudden violent agitation of brief duration and then discontinuing the agitation and allowing the alkaline earth metal silicate to precipitate.  The agitation is for less than 1 second, preferably from 0,001 to 0,1 of a second, and may be effected by introducing the two streams into the central area of a centrifugal pump where they are mixed violently and discharged from the pump into a vessel where precipitation occurs. The agitation may also be effected by passing the streams at high flow rates into the arms of a T-tube and discharging the mixture from the leg.  In the examples pigments are prepared from sodium silicate, hydrochloric acid and calcium chloride, and are beaten with bleached kraft pulp which is formed into sheets of paper.  Other acids mentioned are nitric, nitrous, sulphuric, sulphurous, carbonic, phosphoric, acetic, formic and chloroacetic acids.
