Patent GB-758869-A (GB)
Title: Improvements in or relating to integrating apparatus
Inventor: BRIGGS NORMAN HIGHAM
IPC: G09B9/20
Filed: 1954-04-27
Abstract: 758,869 Electric indicating systems. COMMUNICATIONS PATENTS, Ltd. April 27, 1954, No. 12160/54. Class 40(1) [Also in Group XXXVII] , The invention relates to integrating apparatus in which a variable input voltage drives an integrating motor at a speed proportional thereto. To ensure a linear speed responsive over a wide range: of input signal, the magnnitude of the input voltage effects a variation in the speed- 'input voltage relationship and a corresponding variation in the gear ratio between the motor shaft and an indicator driven in accordance with the shaft displacement. The variation may be effected continuously or in discrete steps. Discrete step variation, Fig. 1. The input alternating voltage is applied at 3 through a summing amplifier 4 to a twophase integrating motor 7 which runs at a speed proportional to the magnitude of the input voltage and in a direction corresponding to the phase sense of the signal, Linearity of the motor speed is effected, over a given range, by negative feed back from the winding 11 of a tacho-generator 9 driven by the motor to the amplifier input. The motor drives through changespeed gearing 13 an indicator 14, e.g. of altitude when the input signal represents rate of climb. The input signal amplitude, regardless of its phase sense, is com- Dared in a modulus amplifier 15 with a present voltage derived from a potentiometer 16 so that when the input signal exceeds this preset value a relay A is energized to increase the negative feed back at contact A1 and so reduce the motor speed in a certain ratio. Relay A through a slugged relay 3 also de-energizes a solenoid 18 to effect a corresponding ratio 'change in the variable speed gear 13, so that the range of variation of motor speed is kept within the linear response portion of its characteristic. Continuous variation, Fig. 2. The input signal at 3 drives the integrating motor 7, as in Fig. 1, the motor driving the indicator 14 through a continuously variable gear 22-25. The gear ratio is adjusted continuously through a rack 35 by a servomotor 26 positioned in accordance with the value of the input signal, and the negative feed back voltage from the tacho-generator coil 11 to the amplifier 4 is varied in correspondence with the gear ratio adjustment by a potentiometer 19 set by the servomotor 26. The servomotor 26 is of the balanced potentiometer type, the input signal and the voltage derived from the motor driven potentiometer 32 being applied in opposition to the motor amplifier 29 which drives the motor until' balance is achieved.

Title: Improvements relating to prepayment gas meters
IPC: G07F15/00
Filed: 1935-04-23
Abstract: 445,146. Prepayment mechanism for gas meters. SOUTH METROPOLITAN GAS CO., CARPENTER, C. C., and SMITH, C. H., 709, Old Kent Road, London. April 23, 1935, No. 12195. [Class 27] Price-changing mechanism.-The valve-closing mechanism or " burning-off " shaft 10, Fig. 1, of a prepayment gas meter is driven from a meter shaft 1 carrying a sun-wheel 2 of an epicylic gear. A sleeve 3 on the shaft 1 carries a disc 4 on which are mounted the pivots 5 of the planet wheels, a striking or clutch member 6 being slidably splined on the sleeve. Normally, when the striking member 6 is engaged with a clutch member 7 fixed to the frame, rotation of the disc 4 is prevented and the drive from the shaft 1 passes through the train of gears 2, 8, 5, 9. After consumption of a predetermined amount of gas, the striker 6 is moved back to engage a clutch member 11 fixed to the shaft 1, so that the sleeve 3 rotates at the same speed as the shaft and the drive passes direct through the epicyclic gear which is locked together as a single unit. Gas is then supplied at a different rate. The striker 6 is moved back by a lever 12, Fig. 2, under the action of a spring 13, the time at which this movement occurs being determined by the position of a notch 14 in a cam 15 which is driven from the shaft 1 through gearing 16. The cam 15 may be reset by means of a shaft 18, a friction clutch 17 being incorporated in the drive 16.

Abstract: 580,301. Tumbler switches. ALLDAY & SON (1922), Ltd., H., and BAIN, R. June 28, 1944, No. 12298. [Class 38 (v)] A tumbler switch is opened slowly by moving the lever d, pivoted at j to bridge member a, so that arcuate contacts f on an arm e, pivoted at k to the lever d, are withdrawn from fixed contacts g against the action of a spring i on a toggle link h. The latter has a slidable connection with the arm e and is pivoted at to the bridge a. This arrangement of the parts, together with the force required to compress the spring i, causes a slow separation, this movement taking place in the direction of the axis of arm e. After the contacts have opened a small distance, the link h moves past the dead centre and snaps the arm e to the left, maintaining constant separation of the contacts in the first part of the movement. When the switch is being closed the toggle mechanism imparts a quick make. Movement of the arm e is limited by extensions e' thereon engaging a recess d' in lever d. Specification 443,748 is referred to.
