Patent GB-897750-A (GB)
Title: Flowmeter
IPC: G01F1/82
Filed: 1960-05-10
Abstract: 897,750. Rotary meters. BENDIX CORPORATION. May 10, 1960 [May 28, 1959], No. 16495/60. Class 110 (2). [Also in Groups XXIX and XXXVIII] The mass flow rate of a fluid stream is evaluated as the quotient of two measurements, one of the linear velocity of flow and the other of the momentum of the fluid stream acting against an elastically-restrained obstacle, the latter measurement being made without the application of any external kinetic energy to the fluid. In Fig. 1, the fluid passes through a hollow body containing a freely-rotatable turbine 18 to measure the linear velocity and an elastically-restrained turbine 16 to measure the momentum, each turbine being preceded by a flow-straightener 15, 17 containing longitudinal blades to eliminate any tangential component in the flow. The velocity turbine 18 has spiral vanes 59 between concentric cylindrical walls 57, 58 so that it is rotated at a speed proportional to the fluid velocity. Magnets 67 in the outer wall 58 co-operate with a pick-up 70 to generate pulses whose repetition rate is thus proportional to the fluid velocity. The momentum turbine 16 has similar spiral vanes 49 upon which the fluid exerts a rotational force against a spiral spring 53, so that the turbine is displaced angularly from its rest position by an amount proportional to the momentum of the fluid. A ring magnet 41 is attached to the turbine shaft and produces an equal angular displacement of a shaft 38 by means of a similar ring magnet 40 attached to the latter shaft. This angular displacement is converted into an electric signal in the device 37 (by means of e.g. a selsyn, E-type pick-up or potentiometer) and passed to a computer 72 which also receives the signals from the velocity turbine. The computer evaluates the ratio of the two quantities and displays the mass flow on an indicator. In a modification (Fig. 2, not shown), the velocity turbine is placed in front of the momentum turbine and a single flow-director is used in front of the first turbine. The flow-director has spiral vanes, while both turbines have longitudinal vanes, and the desired operation depends on the direction of flow not being changed by passage through the velocity turbine. The velocity signal is picked up as in Fig. 1, but the angular displacement of the momentum turbine is sensed by the varying coupling between magnets on the outer periphery of the turbine and two windings on the casing. The secondary winding has three sections to give a selsyn-type output. The device of the invention is particularly suitable as a jet aircraft fuel-meter which can readily be flushed.

Filed: 1937-06-21
Abstract: 493,226. Fluid-pressure servomotorcontrol systems. WHITEHEAD TORPEDO CO., Ltd., and JONES, L. June 21, 1937, No. 17295. [Class 135] Angling-gear for the gyroscopic steering- apparatus of torpedoes and the like comprises a rotatable element 19 which imparts a predetermined angular movement to the chest 12 of the valve controlling the steering engine, the said element also controlling a series of locking members 23 so that on adjustment of the valve chest one of the members 23 positively locks the valve chest in position until further movement is given to the element 19. The valve chest 12 is rotatably mounted in a frame 10 which supports the gimbal system of the gyroscope and to which is rigidly secured a dished element 13 having a peripheral flange to which a ring 14 is bolted or otherwise secured. Keyed to the valve chest 12, is a flanged sleeve 16 to which is rigidly secured a flanged ring 18 and on which is rotatably mounted a disc element 19 carrying above and below it two pinions 20, 21 fixed on a common shaft. The upper pinion 20 meshes with teeth inside the ring 14 and the lower pinion 21 which has a like number of teeth meshes with teeth inside the ring 18. The exterior surface of the flange 181 of the ring 18 has V-shaped recesses 24 which can be engaged in turn by spring- pressed plungers 23 carried by the element 13 and each having a projection 25 by which all except one are retracted from the recesses 24 and this one lies opposite a cam surface 22 in the disc 19. Thus the ring 18 and the valve chest which rotate very slowly compared with the disc 19, are always left locked in adjusted position by one of the plungers 23, and when adjustment is made, for instance by a key or the like applied to holes 26, 27 in the disc 19, this particular plunger is moved clear of the recesses 24 but the surface 22 allows subsequent plungers to engage the recesses so that the ring 18 is finally left locked in position.

Title: Production of p-hydroxybenzoic acids
Inventor: SPIVEY ARTHUR MARSHALL
IPC: C07C51/41
Filed: 1958-06-02
Abstract: The potassium salt of p-hydroxybenzoic acid, or an alkyl-substituted p-hydroxybenzoic acid, is prepared by heating a mixture of the dipotassium and monopotassium salts of the corresponding ortho-hydroxybenzoic acid, the proportion of the two salts in the mixture being such that the ratio of the number of potassium atoms to the number of salt molecules is greater than 1,2 and less than 2. The mixture may be heated under the pressure, e.g. 200 lbs. per square inch, of an inert gas, such as nitrogen.  The mixture of dipotassium and monopotassium salts, which is preferably used in the anhydrous state, can be obtained either by mixing the individual salts or by adding the appropriate quantity of potassium hydroxide to o-hydroxybenzoic acid.  In an example, a mixture of mono- and di-potassium salicylate (wherein the average number of potassium atoms per salt molecule is 1,7) is heated at 220 DEG C. for 3 hours in an evacuated tube.  The product is dissolved in water; and the solution is saturated with carbon dioxide, and then steam-distilled to remove phenol.  The residue from the distillation is acidified, and the free acids are extracted with ether.  A 92% yield of p-hydroxybenzoic acid is obtained.  A very small proportion of hydroxy-iso-phthalic acid is obtained as by-product.
