Patent GB-651140-A (GB)
Title: Improvements in or relating to chlorine gas controlled, pressure-responsive measuring apparatus
IPC: C02F1/76
Filed: 1948-04-07
Abstract: 651,140. Automatic control systems for chlorinators. WALLACE & TIERNAN PRODUCTS, Inc. April 7, 1948, No. 9732. Convention date, April 22, 1947. [Class 38 (iv)] [Also in Groups XIX, XXXVI, XXXVII and XXXVIII] The flow of chlorine in a chlorinator is automatically controlled in accordance with the flow of water in a main. Chlorine from a cylinder 201 flows through a servo-controlled reducing-valve 203, past a metering orifice 204 to a diffuser in a water main 207. Flow of chlorine past the orifice 204 is sensed by change in capacity produced in a differential-pressuremanometer having a capacity/liquid level device (see Group XXXVI), in one leg 210. Flow of water is sensed by a differential-pressureresponsive device 237, connected across a Venturi-section 236 of the main and controlling a potehtiometer 228. The manometer capacitor is energized in series with a full-wave rectifier 230 from a step-down transformer 217 and the D.C. output proportional to the rate of chlorine flow is connected across the potentiometer 228. A portion of this output depending on the water flow is tapped off to energize a relay 234 controlling the two-field reversible servo-motor 246 operating the reducing valve 203. Thus the flow of chlorine is kept constant for any potentiometer setting (i.e. steady water flow) and is adjusted for any rate of water flow. The " dosage " or rate of flow of chlorine to water is varied by a control 250 varying the tapping 214 on the auto-transformer 215 supplying the transformer 217, i.e. by varying the voltage applied to the manometer capacitor. Alternatively the " dosage " control may be effected by an adjustable biassing spring on the relay controlling the servo-motor, Fig. 7 (not shown), and a recording indicator may be connected in series with the control relay (see Group XXXVIII).

IPC: D03J1/00
Filed: 1967-03-01
Abstract: 1,126,997. Testing wear. MONSANTO CO. March 1, 1967 [March 10, 1966], No. 9804/67. Heading G1S. In apparatus for determining the wearing qualities of a surface cover mounted on a stairway, there is provided a rotatable wheel 10 mounting a plurality of cover sample blocks 12, below which is positioned a rotatable foot assembly wheel 32 pivotally supporting foot assemblies 60. As shown in Fig. 4, a carpet sample 74 is secured in stretched condition by means of pin and slot connectors to blocks 12. The shoe assembly 60 has a sample of material suitable for use as a shoe sole, clamped to a spring-loaded arm 76 in a position facing the carpet sample 74, the undersurface of the arm 76 being contoured so that when moved along the surface of a fixed cam follower 100, the arm 76 moves in such a way as to simulate the movement of a foot. In operation, the wheels 10, 32 are rotated in synchronism and although the wheel diameters are the same the orbital paths of the sample block and the sole assembly differ such that as the fixed sample block 12 meets the spring-loaded shoe assembly, the sole sample exerts a force on the sample block to simulate foot pressure on a stair, simultaneously with the foot movement. In an alternative arrangement, the shoe sole sample is mounted on a pair of spring-loaded arms, one of which supports a cam follower, which abuts a fixed cam surface, such that on rotation of the wheel and shoe assembly, the cam follower moves over the cam to simulate foot movement.

Title: Constant output control system for thyristor motor
Inventor: TAKAHASHI JIYUNICHI
IPC: H02P6/32
Filed: 1980-01-11
Abstract: PURPOSE:To realize the constant output control device for the thyristor motor having good power factor and efficiency by setting always the beta-u value at the minimum by compensating the influence of the superposing angle (u) of the command of a set commutation allowance angle beta0 and an armature reaction angle delta. CONSTITUTION:The main circuit current Id is controlled in accordance with an Id command and the current feedback signal from the current detector 5 by a current control circuit 6 and a power source side pulse phase shifter 7. The Id command is inputted to a set commutation allowance angle beta0 command arithmetic circuit 21, which predicts the abrupt increase in the current due to abrupt change in the load or accelerating or decelerating current so as to set the beta0 for compensating the increase in the superposing angle (u) and the armature reaction angle delta. The value beta0 can be set to an optimum minimum value necessary by the signals of the field current If and the angular velocity. The terminal voltage Et tends to lower due to the increase in the Id and the corresponding voltage Vs between the brushes of a DC machine tends to lower, but the current If is intensified so that the Vs may become constant by the Vs control circuit to thereby compensate the decrease in the Et due to the increase in the current.
