Title: Improvements in or relating to side-delivery rakes and like implements
IPC: A01D78/00
Filed: 1958-12-17
Abstract: 891,191. Haymaking machines. BISLEY & CO. Ltd., A. M. Dec. 17, 1958 [Dec. 23, 1957 July 2, 1958], No. 40779/58. Class 6(3). In a semi-mounted hay-making machine of the ground-driven rakewheel type, part 5 of the frame carrying the rake-wheels is detachably connected at various positions to the remainder 4. As shown in Fig. 2, the frame 1 is U-shaped in plan and has two rearwardly-extending limbs 2, 3 to which a part 5 carrying rakewheels 8 is detachably secured. The limb 2 is longer and carries two rakewheels 8 and a swivel ground-wheel 32. The limb 3 normally carries no wheels so that when the frame part 5 is attached to it, the device operates as a swath-turner, the part 5 carrying a swivel-wheel 33 at its rear end. The frame-part 4 is attached to tractor hitch-links by a structure 46 which comprises a turntable 49 carrying, downwardly, a cross-shaft 55 with crank-arms 56 and crankpins 57 for the lower hitch-links and, upwardly, a horizontal pivot 63 to which is attached a pillar 62 connected to the top link ; the pillar can pivot to allow the wheel 33 to remain on uneven ground. The turntable is rotatable about a vertical axis to angle the rake-wheels to the line of draught, and, in a modification, Fig. 18 (not shown), the rotation is effected by rackwork on the turntable which is formed as a winch so that a cable, wound round it and attached to the swivel-wheels, simultaneously adjusts the swivel-axes. The swivel-wheels are spring-loaded and the rakewheels are suspended by cranks which are also spring-loaded by tension or torsion springs. In a further modification, Fig. 19 (not shown), the frame can be angled relatively to the tractor draught-links by a hydraulic ram connected between the cross-shaft 55 and the frame-part 4. In Fig. 24 the frame 1 is rigidly mounted on the cross-shaft 55 which is mounted on a triangulated bracket 150 carried by tractor draughtlinks 132, 136, the top link being connected by a bell-crank 161 and cable 165 to the crank arms 16 carrying the rake-wheels, so that raising the hitch-links lifts the rake-wheels. In Fig. 29 each rake-wheel 8 is carried by a stub axle 118 integral with a sleeve 177 on the frame-beam 1, the sleeve and beam having lugs 181, 180 with an adjusting-screw 182 to determine the inclination of the rake-wheel plane to the vertical. The rake-wheels may be replaced by wheels having weeding or scarifying tines.

Title: Improvements in or relating to magnetic amplifiers
Inventor: OSTERMAN STANE
IPC: H03F9/02
Filed: 1958-12-30
Abstract: 896,702. Magnetic amplifiers. HARTMANN & BRAUN A.G. Dec. 30, 1958, No. 42022/58. Class 40 (9). In a balanced magnetic amplifier with at least two opposed A.C. windings which, in the absence of an unbalancing input signal, fire together half-way through each excitation half-cycle, a non-linear resistor with a large thermal capacity is put in series with each A.C. winding so that when an input signal causes one A.C. winding to saturate before the other a capacitor in the balanced arm of the circuit is charged and, when both cores are saturated to terminate charging, the capacitor discharges in aid of the current in one A.C. winding and in opposition to that in the other so that one non-linear resistor is heated more than the other and the amplifier is thrown off balance. As shown in Fig. 8, the A.C. windings Wa comprising opposite arms of a bridge circuit are wound on identical cores Dr1, Dr2. Each core also has an input winding Ws driven in a series circuit from terminals K. The input circuit may be decoupled from the A.C. windings by means of transformer Tr, driven by the second harmonic voltages which occur across the terminals such as A, B, or A<SP>1</SP>, B<SP>1</SP>, or both, or from across the load arm GH. Variable resistors r1 adjust the decoupling. The load Rv is in series with a choke Drs to reduce the second harmonic component in the output. The load is shunted by a capaciitor C discharge current from which, after uneven firing of the cores Dr1, Dr2, in face of input to windings Ws, causes unequal heating and, therefore, unbalance in the non-linear resistors W1 to W4 in the latter part of each half-cycle of the excitation voltage. An optimum value of the capacitor exists for maximum gain of the amplifier and this determines an optimum value for the load resistor. The amplifier has internal feed-back which is positive if the non-linear resistors have increasing resistance with increasing current and is negative if the resistance decreases with increasing current. A load may be matched to the amplifier by employing external feed-back windings. As shown in Fig. 9, the invention is used in a push-pull circuit supplied from centre-tapped transformer T, second harmonics in the input windings being decoupled, by setting them in opposition to the second harmonics picked out of the load circuit by transformer T. It is pointed out that the amplifier is sensitive to the phase difference between the excitation voltage and an input voltage of twice the frequency U.S.A. Specification 2,388,070 is referred to.

Abstract: 937,793. Vehicles supported by gaseous cushions. SPERRY GYROSCOPE CO. Ltd. Feb. 21, 1962 [Dec. 9, 1960], No. 42467/60. Class 4. A ground effect machine has a plate which is immersed in water during a turn whereby the water exerts on the plate a force having a centripetal component. The plate 1 is carried by the rod 3 of a piston 7 slidable in cylinder 4 on the machine 2, a pin 9 on rod extension 8 sliding in a slot 10 in casing 11 to rotate the plate through 90 degrees as it moves from recess 6 in machine 2. Load exerted on shaft 3 is taken either by a collar on shaft or by piston 7 bearing against a nange m cylinder 4. Two plates are provided in substantially mirror image relationship when referred to the plane of longitudinal symmetry of the machine, both lying abaft of a transverse plane through the C.G. The direction of lift generated by flow over the plate is outwards and downwards and in a plane containing a longitudinal axis of the craft which passes through the C.G. To turn, for example to the right, a propeller on mounting 13 is moved to turn the machine slightly to the right and the right hand plate is immersed to produce a lateral force to the right to enable the turn to be made more quickly. Drag on the plate produces a torque about the vertical axis of the machine to confer weather cock stability on the machine. The plates may be pivoted to the machine, Fig. 4 (not shown).
