Title: Improvements in or relating to rolling mills
Inventor: GILL HEDLEY
IPC: B21B37/50
Filed: 1959-02-26
Abstract: 885,784. Automatic control systems for rolling mills. BRITISH IRON & STEEL RESEARCH ASSOCIATION. Feb. 23, 1960 [Feb. 26, 1959], No. 6701/59. Class 38 (4). [Also in Group XXII] In a method of cold or hot rolling strip in a multi-stand tandem mill in which the strip thickness is controlled during rolling by adjustment of the roll-setting on one only of the stands, the stand selected being other than the last of the mill the roll-setting of the selected stand is automatically adjusted to maintain the thickness of the strip issuing from that stand substantially at a constant value and the speed of the rolls of the stand is automatically controlled to maintain the speed of the strip leaving the stand at a desired value. The thickness of strip issuing from the first or any other single stand of the mill except the last is controlled by the output of an amplifier 30 which operates the control circuit of a screwdown motor 15. The amplifier input signal is proportional to the departure of the thickness of the strip from the desired thickness, measurement of the instantaneous strip thickness being taken at the roll-gap by compounding signals propor- F tional to the mill spring - and the initial rollm setting So by a Wheatstone net 26 and a resistor R 1  respectively arranged in series. The required strip thickness h 1  is represented by a resistor R 2 , the potential drop of which is in opposition to that of R 1  and the Wheatstone net, the input to the amplifier being propor- F tional to - + So - h 1 . The thickness of the M strip may alternatively be controlled manually. To prevent variation in the interstand tension the speed of the rolls 12, 13 of the same stand is controlled either by adjustment of the armature voltage by varying the speed torque characteristic, or by a suitable selection of the speedtorque characteristic of the driving motor or motors 14. When armature voltage control or variation of the speed-torque characteristic are adopted as the control, the speed or tension of the strip is sensed by a tacho-generator 16 or by a tensiometer 34, Fig. 3 (not shown), and the signal from the generator or tensiometer is compared with that from a potentiometer 20, the error being applied to an amplifier 21 the output of which is used either to vary the armature voltage of the driving motor or to control the speed-torque characteristic. If a suitable selection of the speed-torque characteristic is made the change of speed resulting from a change of roll-setting will compensate for a change in strip speed resulting from a changed reduction of the strip, without the use of a tachogenerator or tensiometer sensing control. Specifications 692,267 and 713,105 are referred to.

Abstract: 1,102,751. Electric selective signalling. SERCK CONTROLS Ltd. 31 May, 1965 [1 March, 1964], No. 7076/64. Heading G4H. In a multi-station communication system, a transmitter is provided at each station and is interlinked with receivers at all the other stations, and a station with an alarm condition transmits a pulse coded signal to all the other stations where it is checked, the first divergence from correctness causing the respective receivers to reset ready to accept a further signal. In the particular embodiment, a failing (by generator failure or station overload) electric power generating station transmits the pulse coded signal seven times to trip-out other generating stations to prevent overload. In each receiver, the successive bits of the signal are sampled, and fed to two counters which count correct marks and spaces and control a third counter which totals them, the counters controlling logic to cause reset in the event of error in the signal. In the event of no error, the generating station is tripped-out.

Abstract: 860,824. Hooks and shackles. GARLAND, N. June 7, 1957 [March 8, 1956], No. 7316/56. Classes 24 and 89(2). A mooring-device for ships &c. comprises a bridge 1, Fig. 1, pivoted at 2 between side-plates 54 and held in a position to close a recess 66 by a nose 8 thereon engaging a nose 9 on one end of a lever 3 pivoted at 14 between said plates. The device may be mounted on a buoy or bollard or on the main eye 53 of a shackle mooring-link SML. The other end of lever 3 carries a pin engaged in a hook 11 on a lever 4 pivoted at 13 and urged by its weighted-end 12 to engage the pin. Lever 4 is prevented from turning clockwise by a pivoted-pawl 16 secured by a wedge 18 in a socket 19 in the lever. The wedge and lever 4 are connected by lanyards 51, 20, respectively, to a lanyard 49 carrying a ball- or wedge-shaped weight 45, which is joined by a lanyard 5 to a remote controlling-position. To release a mooring wire 7 held in recess 66, lanyard 5 is pulled to take up all lost-motion, i.e. to raise weight 45, and then to remove wedge 18 from its socket 19. Thereafter, lever 4 is turned clockwise to release lever 3, and a pull on wire 7 will pivot bridge 1 to release the wire. In a modification, hook 11, Fig. 5, of lever 4 is closed by a loop 23 engaging a nose 29 and pivoted by a pin 24 in a slot 25. A lever 26 pivoted at 30 and weighted at 27 has a forked-end 31 engaging pin 24. Thus, to release pin 10, lever 26 is turned clockwise by the lanyard to move pin 24 along its slot, and move loop 23 away from nose 29. When the lever 26 engages stop 32, lever 4 is carried therewith to move hook 11 away from pin 10. In a further modification, hook 11, Fig. 7, is closed by a forked-rod 33 slidably-guided by a slot 44 and attached by a link, (not shown), to a lever 39 normally in a horizontalposition. To release pin 10, lever 39 is turned clockwise by the lanyard, and then pulled along slot 43, thus withdrawing rod 33 to the left. Further pulling on the lanyard, pivots lever 4 clockwise to remove hook 11 from pin 10. Specifications 485,173, 771,644, 772,926, 779,569, 779,970, 781,634 and 798,191 are referred to.
