Patent ES-344801-A1 (ES)
Title: Hydromechanical gauge control system for a rolling mill and like device
IPC: B21B31/32
Filed: 1967-09-06
Abstract: A rolling mill incorporates a roll-gap adjusting rod 16 which bears on an upper roll chock 13 and is formed at its upper end with an integral piston 22, movement of the rod being restricted by an axially adjustable sleeve 26. A spring 34 is located between the piston and sleeve and permits limited movement of the rod, subject to the spring compressibility. The sleeve is moved axially by a worm and pinion mechanism 29 to adjust the roll-gap, and is subject only to the difference between the hydraulic load on the piston and the rolling load. The spring allows, for example, 0À080 inch adjustment of the rollÀgap and can withstand a load of 200,000 lbs. A control circuit for providing automatic gap control, maintains the pressure applied to the piston at a value of P(Y+1) where P is the rolling load and Y is the ratio of the moduli of the spring 34, and of the mill, including the housing 11. Values of the rolling load from a load cell 17, of the mill modulus, spring modulus, and roll and strip width characteristics are fed to the circuit by potentiometers, the output of the circuit controlling the pressure value P(Y+1). The shape of the rod 16, and the disposition of the spring 34 can be changed, Figs. 3-5 (not shown). The rod 16 may be positioned at the base of the housing 11, and may be associated with two-high or four-high mills.

Title: Adjustable current-responsive device
IPC: H01H71/74
Filed: 1967-12-04
Abstract: In an adjustable electromagnetic tripping device for a circuit-breaker, the armature 15 is biased to an unattracted position by an adjustable biasing spring 17 connected to a pivoted adjusting member 21 carrying an adjustable stud 24 with a cam follower head 25 engaging the spiral shaped cam surface 26 of a cylindrical cam member 27 at any of a plurality of radially spaced positions on the surface 26. The " high " and " low " settings are adjustable independently, the adjusting stud 24 being moved without altering the setting of the cam member 27 and the tension of the spring 17 being adjusted by adjusting the anchor member 20 with respect to pivoted member 21. Once the " high " and " low " settings are determined, current setting is by rotating cam member 27 so that cam surface 26 acts on head 25 of stud 24 to rotate the member 21 and adjust spring 17. The armature 15 also carries a calibrating screw 19 which engages a cross-arm 35 extending across one or more trip devices. U.S.A. Specifications 3,084,236 (Specification 994,368) and 3,110,848 are referred to.

Title: A-c voltage regulator
IPC: H02M7/00
Filed: 1967-12-23
Abstract: A no-break standby supply arrangement for a load 88, which is normally energized over an inductor 87 and a line 11 from a primary A.C. line 86, comprises an inverter 10 which is connected to the load 88 by way of a voltage regulating system 23, 24, 26 (see Division G3) the inverter 10 derives its input from a charger 90 which is connected to the A.C. line 86 and which also charges a battery 11, a synchronizing unit 92 being provided so that the inverter output voltage is in phase with the output voltage on line 11. Thus, if the primary supply fails the battery 91 supplies the load over the inverter 10 if the voltage on line 11 should fall, the inverter commences to supply energy to the load and aids the primary supply in addition, if the load voltage becomes too high the inverter operates regeneratively to charge the battery 91 and aids the charger 90. The inductor 87 isolates the load 88 from the effects of a short-circuit on the line 86.

Abstract: A steam generator combustion chamber 1 is bounded by four vertical gas-tight tube walls 16, 17, 18 and 19 and by a tube bottom 20, said walls being surrounded by a girdle of four rigid beams 36, 37, 38 and 39 formed by flanged girders of H- section, pairs of the girders 36, 37, 38 and 39 being permanently joined to form a right-angle, the free ends of adjacent girders having mounted therebetween adjusting means arranged to be controlled so that the circumference of the girdle varies in dependence on the thermal expansion of the circumference of the tube walls. As shown, hydraulic servomotors 4 and 41 are mounted between the free ends of the flanged girders 36, 39 and 37, 38, each servomotor being controlled by a control valve 26 which communicates by pressure medium lines 14 and 15 with the two cylindrical chambers of the servomotor. For the servomotor 4 (the same applies for 41), the complete cylindrical chamber is mounted on the end of the girder 39 while the piston rod is connected by a pivot to the end of the other flanged girder 36. In another embodiment, the servomotors do not directly join the free ends of adjacent girders to each other, instead each piston is pivoted to the long arm of a bell-crank lever (43) which is connected to a link 44, Fig.2 (not shown). Also in this embodiment, each servomotor is under the influence of the pressure which prevails in the combustion chamber 1, a diaphragm cell controlling the pressure in the cylinder of each servomotor.

Abstract: A traction vehicle for semi-trailers, having a fifth wheel coupling 3, has a linkage connecting the front axle 9 to the rear spring 7 on each side of the vehicle, so that vertical movement of one wheel on one axle in one direction is transmitted to the corresponding wheel on the other axle, moving it in the opposite direction, the ratio of the movements being equal to the ratio of the distances of the centre of the fifth wheel coupling from the respective axles. The linkage comprises a pair of bell-crank levers 12 and 15 pivoted to the vehicle chassis at 13 and 16 near front and rear axles respectively and connected by a tension rod 14. A link 11 is pivoted at one end to the bell-crank lever 12 and at the other to the axle 9. The bell-crank lever 15 is connected to the rear end of the leaf spring 7 through a shackle 17. The axle 9 is connected to the chassis 1 through a vee-shaped arm 8 pivoted at its apex to a chassis cross-bar 10. The ratio of the movements of the wheels may be adjusted, for example by moving the pivot point of the tension rod 14 on the arm of the bell-crank lever 12, to correspond to different positions of the fifth wheel coupling 3 which is movable on the chassis 1. The coupling system may be hydraulic or pneumatic comprising a closed piston and cylinder system with the piston areas of the units on each axle being inversely proportional to the distance of the fifth wheel coupling from the respective axles.
