Title: Improvements in apparatus for measuring the rate of flow of fluids
Inventor: DALL HORACE EDWARD
IPC: G01F1/80
Filed: 1952-12-03
Abstract: 741,942. Flow-meters. KENT, Ltd., G. March 3, 1954 [Dec. 3, 1952], No. 30645/52. Class 69 (1). The rate of flow of fluid through a conduit is measured by rotating a Pitot tube in the fluid flow about an axis which is transverse to the direction of flow so that the open mouth of the tube alternately faces upstream and downstream of the flow in each rotation, and measuring the pressure difference at the mouth at each rotation. In one form of apparatus, Fig. 1, the rate of fluid flow in the conduit 1 is measured by a Pitot mouth 3 which is rotated by a shaft 5 driven by an electric motor (not shown) and is connected by the passage 6 alternately to the high and low pressure lines 11, 12 of a differential pressure measuring apparatus. The mouth is mounted on a support 4 in the form of a disc which rotates between one wall of the conduit and a false wall 17 so that the flow to be measured is effectively confined to the inner conduit space 20. In a further form, Fig. 2, the disc 4 carries a pair of opposed Pitot mouths 3, which are each connected to the lines 11, 12 at each rotation. To minimize disturbance of the fluid flow a second rotational component similar in form to the Pitot tubes may be mounted in the flow conduit and rotated in the opposite direction. The form shown in Fig. 1 may be modified by taking a connection permanently open to the passage 6 and connecting to an instrument for measuring the peak pressure. In all forms of apparatus, the pressure difference obtained is directly proportional to the mass rate of flow and the speed of rotation of the Pitot tubes may be varied to obtain optimum measuring conditions.

Patent GB-159071-A (GB)
Title: Improvements relating to the winning of tin
Filed: 1919-12-10
Abstract: Tin-bearing-rocks having a small content of stannic oxide, or "tailings" left after the mechanical separation of stannic oxide, are reduced by suitable gases, and the resulting metallic tin associated with a large quantity of gangue, subjected to the action of anhydrous chlorine, preferably discharged from the liquid condition.  By thus using an ore in which tin may be 4 per cent or less, the heat generated by the action of the chlorine is maintained within controllable limits.  The reaction vessel may also be provided with a jacket through which a cooling-medium may be circulated in order to maintain approximately atmospheric temperature.  The stannic chloride thus produced is separated by leaching with a solvent such as warm water, or caustic soda solution, by distillation on the heated mass. The volatilized stannic chloride is condensed in water and the hydrated chloride used to prepare other tin salts or metallic tin. The latter is extracted by passing the solution of stannic chloride into a series of boxes each containing zinc turnings, spongy tin is precipitated whilst zinc chloride free from tin, collects in the last box.  The addition of a small amount of stannie chloride is found to facilitate the commencement of the reaction between the metallic tin and the chlorine, and if the ore contains arsenic or sulphur these are removed by roasting before the reduction of the stannic oxide. Specification 1401/08 is referred to.

Title: Improvements in and relating to electrically heated thermal control elements, specially applicable to expansion type thermal elements forming overload and/or no-volt devices for electric circuit-breakers, contactors and the like
IPC: H01H71/16
Filed: 1934-10-31
Abstract: 446,672. Thermal switches ; automatic circuit-breakers. COX, F. B., 65, Fleet Street, Liverpool. Oct. 31, 1934, No. 31171. [Class 38 (v)] A thermal switch for controlling an automatic circuit-breaker comprises a bimetallic strip S, Fig. 1, fixed at one end to a terminal T<1> and at the other end to a heating strip H also connected to terminal T<1>. The free ends of strips S, H are connected by a lead F to a terminal T<2>. When an excess current passes through the strips S and H they bend to the right and tilt a bell-crank lever D to separate contacts 4, 5 in the hold-on circuit of a circuitbreaker. The heating element H may be wound on a tube surrounding the strip S. In the arrangement shown in Fig. 2, on failure of voltage across the terminals T<1>, T<2>, strip S bends to the left and rotates lever E to lift a detent 11 and release a circuit-breaker 12. The point 1 passes the end 7 of lever E, and the circuit-breaker may be reset before strip S is heated, as the return movement thereby causes an idle movement of lever E. In another arrangement the point 1 is arranged between two levers E which are operated respectively due to overload and no-volt conditions, to open the circuit of a hold-on coil.

Title: Improved means for eliminating vibration in crank-shafts and other rotating bodies
IPC: F16F15/14
Filed: 1938-10-29
Abstract: 520,787. Crank-shafts. BRISTOL AEROPLANE CO., Ltd., and BUTLER, L. F. G. Oct. 29, 1938, No. 31315. [Class 80 (ii)] [Also in Group XXXII] In crank-shafts or other rotating bodies subjected to both torsional and flexural vibrations, a selected order of torsional and a selected order of flexural vibration is suppressed by a single ball free to roll on a race or track carried by the rotating body. The shape of the race or track 12 is defined with reference to three rectangular co-ordinates, Fig. 1 which shows a crank-web 10 with balance weight 11. The origin is that point of the track which has the greatest perpendicular distance R from the axis of rotation CS; the Z-axis intersects and is perpendicular to the axis CS; the Y-axis is parallel to the axis CS and the X-axis is perpendicular to CS and at a distance R from it. The shape of the race or track conforms or approximately conforms to an elliptic paraboloid, the equation of which is given in the Specification. The race or track may have the shape of a toric surface, Figs. 2. 2A, generated by the rotation of a circle of diameter B about a centre distant A from the lowest point of the track the distances A, B being involved in the equation to the elliptic paraboloid. The distances A, B may be interchanged. In a modification, the track forms part of a cask-shaped surface. The distance B should be the same for both crankwebs, i.e., the balls should both suppress the same order of flexural vibration, but each ball may suppress a different order of torsional vibration so that A may be different for each web. In a construction form, each web may carry two balls such as 13, Fig. 7, carried in a recess 15 in a balance weight 11. Each ball race 17 has a downwardly extending flange 20 secured by a cover plate 19, provided with a slot 22 to drain oil and other matter. Specifications 401,962 and 439,768 are referred to.

Title: A float-operated valve

IPC: B64D37/00
Filed: 1956-10-16
Abstract: 845,284. Fluid-pressure servomotor control systems. PARKER-HANNIFIN CORPORATION. Oct. 16, 1956, No. 31400/56. Class 135. A liquid level control valve assembly for aircraft fuel tanks comprises a fluid pressure operated main valve controlled by a float-operated pilot valve, in which means are provided for lifting the float prior to the filling of the tank to check that the valve is functioning correctly. The main valve 10 comprises a diaphragm controlled closure member 20 loaded to the closed position by a spring 23 and having a restricted orifice 25 permitting fluid pressure to pass to a chamber 24 linked by a tube line 27 to the inlet port 32 of the floatoperated pilot valve 31. With the float 53 positioned as in Fig. 2 fluid from the chamber 24 passes unrestricted through the pilot valve to the tank via passages 41, 49, 48, 56 and outlet passage 43. On the float rising under the influence of liquid level the valve plunger 46 moves to the left and cuts off the flow of fluid through the outlet passage 43, causing a buildup pressure in the chamber 24 and closure of the main valve 10. To check the functioning of the valve a rocker member 57 is provided pivoting about the same axis 51 as the float arm 52 and is biased by a spring to tend to lift the float arm to the valve closed position. This action is opposed by a spring-loaded plunger 62, which can be retracted by a solenoid 65, manually controlled. To test the valve the solenoid is energized to withdraw the plunger 62 permitting the rocker member 57 to lift the float to the valve closed position. Fuel under pressure is then fed to the main valve 10 which should close as soon as pressure equalizes across the diaphragm 21, the outlet from the chamber 24 being closed by the pilot valve. In another embodiment the solenoid may be replaced by an hydraulic actuator also manually controlled.
