Title: Improvements in rolling mill lifting tables, feed tables and the like
IPC: B21B39/04
Filed: 1936-11-20
Abstract: 466,843. Endless - belt conveyers. SCHLOEMANN AKT.-GES. Nov. 20, 1936, No. 31864. Convention date, April 7. [Class 78 (i)] [Also in Group XXII] In receiving work from a rolling mill on driven endless chains 7, or table, and passing it back through or over the mill at a different level by oppositely driven endless chains 6, or table, which is raised to receive the work while the other chains are lowered, the chains, or table, are so timed to cross each other at a point less than half the distance between the plane of discharge and the plane of input and may be substantially in the plane of discharge of the blank from the mill. The crank 12 lowers the outer table and its chain 6 and simultaneously through the lever extension 24 moves the inner table and chains 7 downwardly faster than the chains 6 so that at the bottom position the chains 7 lie below the chains 6. The crank 12 operating the lift and lowering fingers 28, 28<1> allow the push plate 29 and 29<1> on the inner tables to lower until the upper ends of the slots 30, 30<1> rest on the pivot 27, 27<1> thus first allowing the chains 7 to fall and cross the chain 6, i.e. in or substantially in the plane of delivery of work from the mill after which the tables are lowered in unison. The fingers 28, 281 gradually move away from the push plates 29, 29<1> so providing a lost motion travel when the tables start rising again causing relative vertical displacement of the chains taking place towards the end of the rising movement. When the material passes on to the chains at the top, the chains are driving towards the mill to prevent the work being carried off the table by the inertia of the work so that the feed-chain can take charge of the work during table lowering and feed back the work at the lower level. In discharging the material through the lower roll pass and carrying it to the upper roll pass, the fingers 28 are taken off and reversed as shown in Fig. 6.

Title: System for positioning a control element
IPC: G05D1/00
Filed: 1971-07-08
Abstract: 1328592 Fluid-pressure servo-motor systems E-SYSTEMS Inc 7 July 1971 [20 July 1970] 31894/71 Heading G3P [Also in Divisions G4 H2] In a system for positioning an element 82, such as the control surface of an aircraft, at least three transducers 10, 12, 14 each produce an output related to an electrical signal and the outputs are summed into a single mechanical motion applied to an actuator 44. The actuator adjusts servo valves or variable displacement pumps 50, 52 controlling servo-motors 66, 74 providing feedback to the actuator through links 84 and 45. A nut 58 allows the pumps or valves to be synchronized. Each transducer consists of an AC, DC or brushless DC motor 126 connected by a nut 131 and lead screw 132 to an output shaft and by a brush ring 125 to an amplifier, such as 16. A linear differential transformer 136 supplies a feedback signal to the amplifier and a further signal to a comparator 86 arranged to disable a failed channel to operate an indicator 94. The signals from the transducers are compared by differential amplifiers 96, 98 etc, Fig.4, having their output voltages applied to NAND gates 108....113 and NOR gates 114, 116, 118 so that with all channels operating correctly the output of each NOR gate will be at logic zero level. Should one channel differ from the others by an amount greater than a differential amplifier setting, one of the NOR gates will switch to a logic one level. The mechanical outputs of the transducers 10 and 12 are summed by a link 40 which has its movement summed with that of the transducer 14 by a link 42.

Abstract: 864,168. Circumferential flow pumps; gas turbine plant. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 28, 1959 [Oct. 3, 1958], No. 32838/59. Classes 110 (1) and 110 (3). A circumferential flow pump comprises an impeller 25 having a circumferential row of radially-extending blades 26, a housing structure 27 surrounding the impeller, the housing structure defining a main inlet 31 and outlet 34, a secondary inlet 39 and outlet 37, means for driving the impeller 25 in one direction at varying speeds, the main inlet and outlet being angularly displaced in the direction of rotation to a greater degree than the secondary outlet and inlet, valve means for blocking and unblocking the secondary inlet and outlet and means responsive to the rotational speed of the impeller for controlling the valve means. In Fig. 1, the pump supplies fuel to a gas turbine engine and rotates at the same speed as the engines. At low speeds, solenoid valves 41, 42 are closed with a manual switch 48 either opened or closed and fuel enters the pump housing 27 through the main inlet 31 to be discharged at the main outlet 34 after about 250 degrees rotation. The switch 48 is provided for setting the circuit for automatic operation. At about 5000 r.p.m. a speed-responsive switch 46 closes thereby opening the solenoid valves 42, 41. Fuel enters the pump housing through inlet 31, and via a conduit 40 through inlet 39 and is discharged through outlets 37, 34 after 90 degrees rotation. Thus at low speeds the fuel flow rate is moderate with relatively high pressure and at high speeds the flow rate is considerably higher with reduced pressure.

Abstract: 1513128 Pressure reducing valves for brake systems AUTOMOTIVE PRODUCTS LTD 25 July 1975 [25 July 1974] 32887/74 Heading F2F A pressure reducing hydraulic control valve assembly 19 is incorporated into a dual circuit hydraulic braking system to control communication between a tandem master cylinder 15 and front and rear brakes 12 and 14 respectively and comprises tubular components 23 and 24 forming a stepped through bore housing stepped pistons 34 and 49 associated with rear and front brake circuits respectively. An integral plunger 20 of the piston 34 engages a leaf spring 21 resiliently connected to rear axle 22 such that rear axle load variations cause variations in the spring force on plunger 20. When the pressure transmitted to the valve reaches a certain level dependent on the ratio of the effective areas of the pistons 34 and 49 the pressures in bores 25 and 31 are sufficient to separate pistons 34 and 49 against spring 74 and leaf spring 21 closing ball valves 41 and 62 which control communication between master cylinder 15 and brakes 14 and 12 respectively. Further increase in pressure transmitted from master cylinder 15 causes a pressure build up in annular spaces 45 and 66,without increase in brake pressure eventually forcing the pistons 34 and 49 together again and reopening valves 41 and 62. This separating and closing cycle is repeated as master cylinder pressure increases having the net effect that the rate of increase of brake cylinder pressure is less than that generated in the master cylinder. Alternatively a second spring may be provided to act directly on the piston 49.

The wires for a stranding machine are drawn from a supply such as reels 14, Fig. 1, or static coils in supply cylinders, by a capstan wheel 63 having different sized diametrical surfaces such that the wires can be drawn from the supply at different rates according to their position in the different layers of the stranded rope or cable. In Fig. 4, the wires for a nineteen-wire strand are assembled by passing the centre wire 38 over the central and smallest diameter of the metering wheel. The six intermediate wires 38a are guided, three on each side, of the centre wire, on to the intermediate steps of the metering wheel. The outer twelve wires 38b are guided, six on each side of the centre wires, on the outer and largest flanks of the metering wheel, these flanks being of greater diameter than the intermediate steps. The wheel 63 may be smooth and polished or may be roughened as by knurling or impregnating it with, or securing to the surface thereof, friction material such as carborundum or other grit. Alternatively, for use with ferrous wires, the wheel 63 may be magnetized. Braking the supply reels 14.-Each reel 14 is carried by a shaft in a cradle 13, the shaft being rigidly coupled to a brake drum, not shown. Pivoted to each cradle 13 are a pair of spaced levers 19 carrying a wheel 22 over which the wire is drawn from the reel 14. A brake belt, not shown, extends between the cradle 13 and the levers 19 such that as the levers 19 swing forwardly under the pull on the wires, as extended by the capstan wheel 63, the brake belt acts on the brake drum to restrict the motion of the reel. The forward motion of the levers 19 is opposed by spring means. Stop motion.-The wires passing from the wheel 63 pass over pulley wheels 68 and thence between wire failure device arms 58 and 59. These arms are used in a well-known manner to connect a relay circuit to cut off the driving motor if a wire breaks and comes into contact with one of them. Before the wires reach the wheel 63 they pass over a number of sheaves 52 and then through a guide plate 60.
