Title: Apparatus for attaching implements to tractors
Inventor: FITZPATRICK HUGH JAMES
IPC: A01D67/00
Filed: 1962-06-06
Abstract: 1,046,245. Tractor/implement hitches. MASSEY-FERGUSON G.m.b.H. May 27, 1963 [June 6, 1962], No. 21846/62. Heading B7T. A tractor/implement hitch for offset towing comprises, a pair of arms 1, 2 connected by a brace 3, Fig. 5, having front ends 4 connected by pivot bolts 5, Figs. 1, 2, to the tractor, power lift links 9, 11, 26 releasably connected by pins 10 to the frame, hinged bearing halves 6 which may be opened and closed about a transverse beam 7 extending across the tractor and implement, arms 18 rigid on the beam connected by links 19 to the tractor, and a trailer coupling connection above or below the beam 7. In order to connect the tractor to the implement, the arms 1, 2 are slipped over the bolts 5 and the draft links attached to the arms by the pins 10. The tractor is then reversed to bring the hinged open bearings 6 beneath the beam 7. The lift links then raise the bearings into engagement with the beam and the bearings are closed around the beam. When the beam is raised by an amount 16 to lift the implement from a working position 12 to a transporting position 14, the beam is rotated clockwise by the links 19 in the bearings 6 so that the implement is given a clearance 17 from the ground which is greater than the lift 16, and adequate clearance 15, Fig. 1, is provided for the trailer draw-bar shown in an upper coupled position. In another embodiment, Fig. 3 (not shown), the trailer is coupled below the level of the beam 7 and the two links 19 are replaced by a single link which is so related geometrically to the arms 1, 2 that the attitude of the implement when lifted remains unchanged. In both embodiments the beam 7 is jointed at 35 so that the implement may be towed directly behind the tractor, and power take-off gearing 21-25 is taken through the beam to the implement. During lifting of the implement the movement of the offset weight is transmitted through the beam 7 and the frame 1, 2, 3 directly to the bolts 5 and the tractor, so that the power lift linkage is relieved of twisting stresses.

Title: Improvements in and relating to electrical circuits and apparatus including grid controlled gaseous discharge tubes
IPC: H01J17/04
Filed: 1934-07-27
Abstract: 444,810. Valve circuits. DALTON, J. W., 17, The Crescent, Belmont, Sutton, Surrey. July 27, 1934, No. 22027. [Class 40 (v)] In a gas-filled discharge valve wherein the anode circuit is intermittently broken, the voltage induced across the load during one discharge is prevented from altering the critical grid-voltage required to trigger the valve for the next discharge. This result is secured either by applying part of the voltage induced in the load circuit to the grid in a compensating direction, or by inserting a rectifier so as to prevent the extra induced voltage from reaching the anode of the valve. As shown in Fig. 1, a tapped auto-transformer 12 applies a compensating voltage to the grid of the valve 10 each time the interrupter 14 varies or suppresses the discharge. In Fig. 2, the arrangement is used to control the voltage of a D.C. generator or the speed of a D.C. motor. The armature windings of the generator 17 and a series regulating-resistance 28 are both arranged in parallel with a condenser 22 and part of a tapped auto-transformer 23, the other part of which induces a compensating-voltage into the grid of the discharge tube 21. The interrupter 20 may be arranged on the shaft of the generator. In Fig. 7 the induced voltage across the load 67 is shunted by a rectifier 68 away from the anode of the discharge valve 61. A second rectifier 64 in series with an A.C. source 65 provides a periodic suppression voltage which takes the place of the interrupter 14 in Fig. 1. Fig. 10 shows the arrangement applied to produce " quiet " interstation tuning in a wireless receiver. When the incoming signals reach a predetermined strength, the negative voltage applied from the valve 88 through a rectifier 90 to the grid of the gas-filled valve 92 is sufficient to outweigh the positive voltage applied to it through resistances 94, 91 from an A.C. source 100, so that the valve 92 does not discharge and the output valve 102 passes the signals into the loud-speaker. But if signal strength is below a predetermined limit, the valve 92 discharges and applies a cut-off bias through the resistance 97 to the amplifier 102, so silencing the loudspeaker. The rectifier 96 serves to prevent any undesired triggering effect. The invention is also applicable to photo-telegraphic systems, and to the production of engraved surfaces or blocks and for the treatment of photo-mechanically-produced surfaces of the kind described in Specifications 389,102 and 391,838.

Abstract: 811,669. Displacement measuring. ELECTRIC & MUSICAL INDUSTRIES Ltd. July 10, 1957 [July 18, 1956], No. 22185/56. Class 40 (1). A displacement measuring device, which may be used for example to measure the relative displacement between the base of a machine tool and a slide mounted thereon, comprises a scale having a zig-zag conductor and a cursor having at least one conductor of similar configuration and adapted to be mounted in proximity to the scale so that relative displacement can occur between the scale and the cursor in a predetermined direction, the limbs of the conductors being oblique to this direction. The device is such that electrical signals can be transferred by electromagnetic induction from one conductor to the other with an amplitude ratio responsive to the relative displacement. As shown, the scale comprises a glass plate 2 having a conductor 1 applied thereto by a silver etching process. The cursor 3 carries two relatively short conductors 5, 6, corresponding limbs of the two conductors being displaced relatively to each other by (2n+¢)p where n is an integer and p is the spacing of the limbs of conductor 1. Further conductors la, 5a, 6a may be provided as shown to cancel out any error due to relative sidelash between the scale and the cursor. Alternatively a sidelash detecting device similar to that shown but wherein the limbs of the conductors are parallel to the predetermined direction 4 may be used to drive a servomotor which displaces the cursor 3 to annul the sidelash or removes the effects by means of differentials after the output voltages of the displacement measuring device have been followed up.
