Abstract: 930,191. Rotary meters. ROTRON CONTROLS CORPORATION. Nov. 14, 1960, No. 39040/60. Class 110 (2). [Also in Group XXIV] A system for remotely recording and indicating the liquid flow through a rotary flowmeter F, Fig. la, of the vortex velocity type, comprises a Selsyn transmitter 1, Fig. 1, connected to the flowmeter rotor by a magnetic pick-up and to a Selsyn receiver 2 driving through gearing 3, 4, a worm-screw 5. The worm-screw 5 co-operates with an idler wheel 6 carried in a casing 6<SP>1</SP> having a finger 31 which moves to release pressure on a spring-loaded plunger 30 to adjust the position of a potentiometer 29 and towards a switch 24. On the switch 24 being contacted, a variable speed motor 9 begins to operate, and through a sprocket drive 10, 10<SP>1</SP> rotates a cone 15 to frictionally drive a roller 16 urged by a spring 20 into engagement with the cone. The roller 16 through a gear train 21, 22, 23 drives a worm-screw 7 to move the casing 6<SP>1</SP> in a direction opposite to its original direction. The motor 9 is also connected to a motor controller 25 and through the positioning of the potentiometer 29, the voltage imput to the motor 9 is varied to vary the motor speed in accordance with flow through the flowmeter. The worm-screws 5, 7 rotating in opposite directions maintain the casing 6<SP>1</SP> stationary under steady operating conditions. Any variation in flow will result in the re-positioning of the casing 6<SP>1</SP> with a corresponding adjustment of the speed of the motor 9. The motor 9 also operates through a belt-drive 62, a flow rate indicator 63, through a sprocket drive 71, a total flow indicator 68 and through a sprocket drive 66, a ticket printer 65. The cone 15 slidably mounted on a shaft 13 co-operates with a yoke fitting 43 movable by a screw 45 to adjust the position of the cone to establish a desired meter factor or apply any other corrections. The yoke is movable through a gear train 53, 52, 50, 49 on the closing of a reversing switch 47 to drive a reversible motor 46. The meter factor is recorded on an instrument 57 driven by the motor 46 through the gearing 49, 50 and a sprocket drive 56.

A fluid pressure relief valve has a spring element formed by a member of rubber-like plastics material having a Shore hardness of at least 80‹, and preferably as high as 95‹, and a modulus of elasticity of at least 100 kg./sq. cm. and preferably about 800-1000 kg./sq. cm., at room temperature, in which a valve closure member, formed integral or carried by the element, is loaded by the element towards a closed position, the element being subjected to a preliminary compression sufficient to remove any further permanent deformability in the required working pressure range. In the embodiments shown in Fig. 2, the valve has a cylindrical rubber-like plastics element 24 located between two flanges 29, 30, the flange 29 being axially adjustable by a nut 26 while the flange 30 carries the closure member 31 which is preferably of the same material as the element 24. In a modification the flange 30 is omitted and the element 24 acts as the closure member. The member 24 is preferably formed with a length to diameter ratio of 7 to 5 and is preferably pre-compressed at a pressure twice the opening pressure of the valve. In a further modification a valve seat 36, Fig. 4, is slidable in the valve housing and the element 24 also acts as a closure member. The element 24 abuts a boss 43, of smaller diameter than the seat opening 40. As the pressure rises the sleeve is urged towards the element 24 by the fluid pressure acting on the lower end until the element 24 flexes to open the valve. The seat is then moved downwards by the static and dynamic pressures acting on its closing end. In a further modification the boss 43 is formed on the end of a flange such as 30 of Fig. 2. In another modification the element, also acting as the closure member, is of barrel shape and bears at its end opposite the seat against an adjustable nut having a concave bearing surface.

Title: Device for adjusting the power supplied to a load from a rectified alternating voltage source by suppressing half cycles
IPC: H02M1/08
Filed: 1974-09-26
Abstract: 1485786 Controlling A.C. power supply SILEC-SEMI-CONDUCTEURS 26 Sept 1974 [26 Sept 1973] 41922/74 Heading H2H In a circuit for controlling A.C. by suppression of full half-cycles, a semi-conductor switching device 10 is connected across the output of rectifier 6 and is controlled by a threshold device 3 supplied with a signal by a capacitor 11 connected to the anode or one of the main electrodes of device 10. The device 10, which may be a triac, is of the type turned on by negative gate pulses. As described, the capacitor 11 is connected to an intermediate point on a series RC phase shifter 2 supplied with positive half-cycles of the A.C. from the D.C. side of bridge rectifier 6. After a number of half-cycles (depending on the value of resistor 12), capacitor 11 is sufficiently charged to break down the threshold device 3 (Zener diode or diac) and trigger the junction gate thyristor 10. The resulting current in bridge rectifier 6 turns on triac 5 which passes a full half-cycle through the load 4. The sequence then continues, the proportion of half-cycles of the A.C. passed to load 4 being a function of the value of resistor 12 which may be controlled manually, optically or thermally. Components 41 ... 48 may be included to allow the load 4 to receive the same power when the A.C. terminals Va are connected either to 220 or 127 v. When a low supply voltage is employed, diode 47 charges capacitor 43 so that thyristor 10 is permanently conductive, hence triac 5 passes all half-cycles to the load 4. When used with the higher supply voltage, Zener diode 46 breaks down, turning on transistor 41 so that thyristor 10 suppresses appropriate half cycles as described above. In Fig. 5 (not shown) transistor 41 is short circuited and a signal is fed to the gate of thyristor 10 via a Zener diode and conventional diode.
