Title: Plating thickness meter
IPC: G01B7/06
Filed: 1948-09-29
Abstract: 649,490. Electric tests &c. current measuring. CARNEGIE-ILLINOIS STEEL CORPORATION. Sept. 29, 1948, No. 25407. Convention date, June 8. [Class 37] [Also in Group XXXVIII] The amount of thickness of metal electrolytically deposited on a moving strip S in a bath 2 is measured by deriving and comparing potentials proportional to plating current and strip speed. Separate anodes 8, 10 on opposite sides of the strip S are fed from separate generators 14, 16 the two generator currents and hence the thicknesses deposited on the opposite sides of the strip being compared in a ratio meter 30 which may be provided with auxiliary contacts 37 to actuate signals or control the ratio. The total plating current passes through a shunt 38 to produce a proportional potential drop across series connected resistors 46, 48. A tachometer generator 54 driven by the strip feed rollers 12 produces a potential proportional to the strip speed across a potentiometer 60 the moving arm 68 of which taps off a fraction of this voltage which is normally balanced against the potential drop across the resistor 46 in a contact making galvanometer 44. If the balance is upset the galvanometer at its contact 76 energizes the appropriate field 81 of the series motor 70 whereby the motor rotates in the corrective sense to restore the potential balance by adjusting the poteniometer arm 68 and at the same time actuating a pointer 82 to indicate the deposit thickness or amount in lbs. per base box. Variations in width of the strip are catered for by a potentiometer 58 manually set in accordance with the width to vary the proportion of the tachometer voltage applied to potentiometer 60. A similar potentiometer 50 set in accordance with the plating efficiency adjusts the potential across resistor 46. To return the indicator 82 to zero when the bath 2 is not functioning a voltage derived from an A.C. source 100 and rectifier 86 is fed to the potentiometer 60 to cause the motor 70 to zeroize the pointer. This voltage is disconnected during normal working by a relay 92. The potentiometer 60 may also be provided with contact making mechanism to operate an alarm should the coating thickness deviate beyond allowable limits.

Abstract: 957,625. Fibre preparation machines &c. COTTON, SILK & MAN-MADE FIBRES RESEARCH ASSOCIATION. July 16,1962 [July 14, 1961], No. 25506/61. Heading D1N. [Also in Division G3] The amount of fibrous material, e.g. cotton, fed to the beater 11 of a scutcher is determined by the speed of pedal roller 21 which is controlled in response to short term variations in the thickness of material at the pedal roller, while the datum about which such control is effected is varied by long term signals derived from variations in thickness of the web of material leaving the cages 12,13 at calender rollers 14... 16, the reference level about which the variations are measured being readily preset to desired values according to previous experience of the raw material. Adjacent the pedal roller is an arm 22 pivoted on a knife edge 23 and connected by a "piano link motion" 24 to a member 25 controlling the position of a belt 30 forming part of a conetype variable speed drive for the pedal roller, which is thus varied inversely as the thickness of material passing between the roller and the arm 22. The member 25 is pivoted about a pin attached to a lever 34 whose position is adjusted by a servomotor 32 in response to signals from a transducer 31 sensitive to the height of the calender rollers 14... 16. The signals may be continuously variable or indicative of upper and lower limits only. The transducer is carried on a pivoted arm whose free end bears on an adjustable platform, the height of which is preset by hand-turned gearing incorporating a counter; adjustment is made so that the counter registers a number found, by previous experiment, to result in a desired weight per unit length for a given raw material, on that particular scutcher (Fig. 2 not shown). There is preferably a transducer on each side of the top calender roller, and there may be means for switching-off the servomotor during doffing operations. The motor may also be fitted with limit switches.

Title: Improvements in or relating to number responsive devices
IPC: H04Q3/62
Filed: 1947-09-19
Abstract: 634,695. Electric selective signalling. STANDARD TELEPHONES & CABLES, Ltd. Sept. 19, 1947, No. 25538. Convention date, Sept. 8, 1942. [Class 40 (i)] A uniselector is used for selection in accordance with two digits by allotting certain digit values to the first digit position and the remainder to the second. The switch responds to the first digit to operate a relay register, which effects wiper-selection, and then goes home. If the next digit received is one allocated to the first position, the original setting of the relay register is cancelled and the new one taken up. In response to a second digit, the switch pauses on the selected position to send a control impulse over the effective wiper and then goes home again. Since the relay register retains its setting until another " first " digit is sent, further control impulses may be sent by dialling a succession of " second " digits. Circuit arrangements. As shown, Fig. 1, 21 different control numbers are available by utilising an 11 position, 5 bank rotary switch, with 1 to 7 as the unit digits, and 8, 9, 0 as the tens digit. When the dial Cd is moved off normal, line relay 11 pulls up and is followed by relays 13, 15 which lock up. Relay 11 follows the dial interruptions and repeats impulses to the driving magnet Cm of the uniselector. At the end of the digit, 13, 15 fall sluggishly in succession and provide a temporary circuit for one of the relays 12, 14, 16 according to the position of the switch. This relay locks up and renders effective one of the wipers Cmb ... Cmd. On the relapse of 15, the switch goes home by self-interruption. The switch responds in a similar way to the second digit, the relapse of 13; 15 this time producing an impulse on the line selected by the effective wiper before the switch goes home. The relay 12, 14 or 16 remains locked up until the operation of another relay of the group by another " first " digit. The control signal energizes a relay such as 17, 18, 26, 27, 28. Except in the case of relays such as 28 which merely cancel a previous signal by unlocking an energized relay (27<SP>1</SP> in this case), the relays that respond to the temporary control signal are associated respectively with relays such as 171 ... 261 and 271 which lock up and energize contactors, e.g. 29 ... 38 and 39 which effect the desired operation. As shown, the operation of any signal-responsive relay 17 ... 26 (but not 27) shunts out any operated relay 171 ... 261 and the relapse of the previously operated relay has to take place before the relay 171 ... 26<SP>1</SP> corresponding to the new signal can operate. Also, the operation of any relay 17 ... 26, 17<SP>1</SP> ... 261 energizes a relay 40 temporarily to give a temporary cancellation of the control exercised by relays 27, 271.
