Title: Control of strip tension in rolling mills
IPC: G05D5/02
Filed: 1971-08-25
Abstract: 1326157 Rolling mills NIPPON KOKAN KK 25 Aug 1971 [26 Aug 1970] 39773/71 Heading B3M In a method of controlling a cold tandem strip mill having stands 1 and 2, the tensile stress acting on a rolled strip is kept constant despite changes in its width or thickness. The method is applicable to a mill in which lengths of strips having different widths or thickness are joined together before rolling, to provide one continuous strip. The thickness of the strip is measured by a counter 7, its width by a counter 8, and its tension by a meter 9. The thickness and width signals are fed to a multiplier 10, and to a calculator 11 which provides a signal corresponding to the desired total tension in the strip. This signal is compared with the actual tension from the meter 9, and any error signal is used to control the speeds of the stands or the screwdown of stand 2 so that the error signal is reduced. Instead of the thickness counter 7, a load cell and screwdown position indicator associated with stand 1 may be employed. To compensate for the different positions of the counters 7 and 8 and meter 9 relative to the strip, delay circuits which are sensitive to the strip speed, may be positioned between the counters and the multiplier 10.

Title: Improvements in or relating to stop motions for warping machines
IPC: D02H13/00
Filed: 1957-12-23
Abstract: 879,574. Warp stop-motions. RUTI MACHINERY WORKS Ltd. Dec. 23, 1957 [Dec. 28, 1956], No. 39957/57. Class 142(1) In a warp stop-motion having a feeler for each yarn, the failure of a yarn causes the feeler to complete a circuit whereby a thyratron will fire and a relay will cause the loom to stop. In one embodiment (Fig. 2), each yarn passes over a feeler 19 urged upwards by a spring 25, the gearing being guided between guides 31. When a yarn fails, the feeler 19 moves upwards to engage a contact 24 thereby closing a contact 50 (Fig. 3). A condenser 47 is charged gradually and when the voltage of an electrode 43 reaches the ignition value the thyratron fires and a relay 44 operates a contact 51 in the circuit of an electromagnet which stops the machine. The slight delay in firing can be adjusted by suitable choice of the condenser 47 and of a resistance 49. If no time lag is required, the condenser can be dispensed with. In a second embodiment (Fig. 5) the feeler 71 pivots about a shaft 64 and on yarn failure the respective feeler falls and engages a rod 75 thereby causing the turned down end 65 of the shaft 64 to close the contact 50. With either embodiment, the circuit contains a spring loaded switch 46 which when opened extinguishes the thyratron and when reclosed restores the stopmotion to its initial position. Alternatively, a resistance is inserted between the relay 44 and one pole of the current source and a normally open switch is provided between the end of the resistance remote from the one pole of the source and the other pole of the source whereby on closure of the switch the source is short circuited and the relay is de-energized. Each thyratron 40 is arranged in an upright member 10 at the same level as its associated group of feelers to provide a visual indication of yarn failure.

[Also in Divisions B7, F2 and G1] A device which is adapted to either arrest or release a movable control member on the occurrence of a predetermined amount of vibration, change in gravitational force (owing to acceleration or deceleration), temperature, pressure &c. consists of a cylindrical container partially filled with steel balls, and a paddle wheel rotatable about a normally vertical axis disposed so that the paddles are either partially immersed in the balls or lie just above the balls, a biasing force being applied to the paddle wheel, tending to rotate it, such that, in the former case, the paddle wheel is normally prevented from rotating but can rotate on the occurrence of more than said predetermined amount of vibration or other physical change which affects the forces resisting relative movement between the particles, or, in the latter case, the paddle wheel rotates under-the biasing force until such vibration &c. exceeds the predetermined amount whereby the balls obstruct the paddles and arrest them. The device may be used to operate a lift safety device when the lift reaches a predetermined degree of free fall, at which the gravitational reactions between the balls and the container may be arranged to be reduced sufficiently to allow rotation of the paddle for this purpose. Other applications of the device are also referred to (see Divisions B7, F2 and G1).
