Abstract: 1,181,941. Presses. NORTON TOOL CO. Ltd. 3 Feb., 1969 [8 Feb., 1968]. No. 6269/68. Heading B5F. A press having a C-frame is provided with means for counteracting the bending force on the press frame comprising at least one tie-rod 27 connected across the gap of the frame and tensioning means adapted to apply to the tie-rod a tensile force substantially proportional to the pressing force. In the hydraulic press in Fig. 1 the tie-rod 27 carries a piston 30 in a cylinder 29 connected to the cylinder of the press piston 18. By making the areas of the piston 30 and 18 in the inverse ratio A/B, where A and B are the distances of the axes of the two pistons 18 arid 30 from the centre of bending 24, the bending effect of the hydraulic ram is neutralized by the tension in the tie-rod. In a modification (Figs. 2, 3, not shown) the tensioning means comprises an annular hydraulic cylinder (41) and piston (42), one end of the tie-rod (37) passing through this annular arrangement and having a collar (44) and flange (45) bearing against the piston (42). The other end of the tie-rod (37) is attached to the press frame in a quickly detachable manner. In Fig. 5 (not shown), the hydraulic tensioning means (60) acts upon the rear end of a lever (65) the front end of which is pivoted to the press frame, one end of the tie-rod (68) being connected to an intermediate point (69) of the lever (65) and the other end being connected to the press frame. Fig. 6 shows a mechanical press having a rotary crank 71 connected by a connecting-rod 73 to a slide member 74. Between the rod 73 and slide 74 is a load sensing device comprising a cylinder 78 and piston 79. The space above the piston 79 contains hydraulic fluid which is put under pressure on the working stroke of the press. This space is connected to the tensioning means 28. In a modification the crank press may utilize an electrical strain gauge controlling a pressure valve of an hydraulic tensioning system.

[Class 37] An induction type meter has a braking system which includes a permanent magnet and two projections forming part of the frame of magnetic material the permanent magnet and projections being so arranged that the rotor can be removed without disturbing the braking svstem. In the construction shown in plan in Fig. 2 and side elevation in Fig. 3, the main frame 1 is of cast iron and carries the driving magnets 2, 3 and bearing 4, 5 for the rotor pivots. The U-shaped braking magnet 8 is of alnico or other steel having a coercive force greater than about 250 oersted. It is mounted on a brass spacing block 9 and is held in position by a brass strap 91 so that the faces of both poles lie in a plane parallel to and below that of the disc 6. Above each pole of the magnet 8 is a cast projection 11 from the main frame 1, the crosssection of each projection being sufficient to take the braking flux. These projections have surfaces 12 in a plane parallel to and above the plane of the disc and are disposed one on each side of the rotor spindle. Withdrawable bearings for the rotor pivots are locked in position by screws 13, 14. After withdrawing the bearings the rotor may be removed without disturbing either the driving or braking systems.

Abstract: 609,805. Fluid-pressure servo motor-control systems. POLSON, R. A., METROPOLITAN VICKERS ELECTRICAL CO., Ltd., and VICKERS-ARMSTRONGS, Ltd. April 28, 1943, No. 6743. [Class 135] A control-system for a power-driven movable object has means responsive to the fluid pressure applied to the power device coupled by means of a dashpot or equivalent means transmitting a force increasing with the rate of change of displacement of said pressure responsive means, with a movable element controlling the supply of liquid to the engine so as to superimpose on the response of the control means to the misalignment between the movable object and the primary control member a response dependent on said pressure and the rate of change thereof and acting in the direction to oppose changes in said pressure. As shown in the Figure, the movable object is moved by a simple hydraulic ram or by a rotary hydraulic engine 2 supplied by a variable delivery pump 7. The pump is regulated by a member 8 actuated by a doubleacting piston 9 under the control of a valve 16. This valve is actuated by a floating lever 29 connected at one end to a moving coil relay device 1 as described in Specification 592,208, so as to receive a displacement dependent upon. the misalignment between the movable object and the control member and upon the first time derivative of said misalignment or the relay may be responsive to the misalignment alone. The other end of the floating lever is loaded by a spring 30 and is coupled to a dashpot piston working in a cylinder 28 connected by a link 27 with a lever 24 turning on a fixed pivot 25. This lever is loaded towards its mid-position by opposed springs 26 and is actuated by a pair of opposed pistons 17, 18 working in cylinders 19, 20 connected by conduits 21, 22 to the conduits 5, 6 connecting the hydraulic engine with the variable delivery pump. In a modification, the hydraulic engine is controlled by a piston valve with tapered ends coupled to the piston 9. In this form the cylinder 28 is connected to the mid-point of a second floating lever connected at one end to the lever 24 and at the other to the piston 9. Specification 609,804 also is referred to.

Abstract: 501,179. Cathode ray tubes. STANDARD TELEPHONES & CABLES, Ltd. March 4, 1938, No. 6851. Convention date, May 29, 1937. [Class 39 (i)] In a cathode-ray device comprising means for causing a beam of electrons to trace a continuous path over one side of a target so as to lay dowii electrostatic charges on successive portions thereof, and means for causing a second beam to trace a continuous path over the other side of the target so as to remove successively the charges laid down a predetermined time interval before by the first beam, the target comprises a plate of insulating material which is pierced by a number of conductive elements or electrodes passing from one side of the plate to the other, and these elements are associated with a common conductor or counter electrode, insulated from the elements so as to form'a number of condensers. The cathode-ray tube is divided into compartments 11, 12 by a target 13 comprising an insulating plate, through which are inserted plugs 46 of nickel or other conducting metal, arranged in a circle and which may be coated on the side 11 with carbon or on the side 12 with alkaline earth oxide. A ring 45 surrounds the target. In the tube 11 a cathode ray is produced by a heated cathode 18 and modulated by an element 34, in the input circuit of which are a resistance 25 and biassing battery 26, and condenser 23. The accelerating and focusing electrodes, 15, 16, and 17 are successively at higher potentials and a further potential difference is maintained between the lining electrode 17 and the ring 45. In the tube 12 the arrangements are the same except that a collecting electrode 60 is biassed positively with respect to the ring 45. In series with the electrode 60 is a resistance 38, across which is connected the primary of an output transformer connected to the first stage of an output amplifier. The deflecting plates 58, 59 and 51, 52 for the input and output cathode rays respectively, are connected across capacities and resistances 57, 56 and 53, 54 respectively, and these are supplied with a sinusoidal current so that the two cathode rays traverse a circular or elliptical path. A settable phase shifter 55 permits the phase difference between the sweeps of the two rays to be altered up to 360. Charges corresponding to the modulated input current are laid down on the elements 46 by the input ray, and are successively discharged to the electrode 60 by the secondary emission excited by the output ray. The elements may be arranged in an elliptical formation, or in rows in the meshes of a conducting grid which is embedded in insulator, the deflecting potentials being correspondingly altered.
