Title: Improvements relating to vehicle guidance systems
Inventor: LAWSON ROBERT
IPC: G05D1/02
Filed: 1962-03-23
Abstract: 1,030,873. Inductive control of vehicles. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. March 22, 1963 [March 23, 1962], No. 11256/62. Heading H4U. [Also in Division G1] A vehicle guidance system, e.g. for a pair of tractors drawing ploughs or the like, comprises controlling and controlled vehicles, the controlling vehicle carrying means for producing an alternating magnetic field and the controlled vehicle carrying magnetic sensing means arranged to be controlled by the magnetic field to produce an electrical output for the operation of the steering mechanism of the controlled vehicle to maintain it in a predetermined position relative to the controlling vehicle. The controlling tractor T1, Fig. 1 (not shown), carries a device D1 mounted adjustably on an arm AR and comprising a coil C1 on a ferrite core which is energized at a frequency of about 10 kc/s. to produce the magnetic field. The controlled tractor T2 carries a magnetic sensing head D2 adjustably mounted on boom BO and comprising mutually perpendicular coils C2, C3 on ferrite cores and arranged so that when the controlled tractor is moving in the required direction no voltage is induced in coil C3 but a reference voltage is induced in coil C2 dependent upon the spacing d between the two tractors. If the tractor T2 should deviate from its correct course a voltage will be produced in the coil C3 having an amplitude dependent on the amount of deviation and a phase relative to the reference voltage corresponding to the direction of deviation. The voltage produced in coil C3 is compared with that produced in coil C2 and an output derived which controls the steering mechanism to restore the tractor to its proper course. The reference voltage from C2 may be compared with a further fixed reference voltage representing the desired distance between the two tractors to provide an output signal controlling the speed of the tractor T2. The controlled vehicle may itself control a further vehicle in a similar manner. Additional signals such as for raising or lowering a plough or operating a clutch may be provided by further transmitting and receiving heads operating at different frequencies. Alternatively, the signal supplied to head D1 may be modulated, a demodulator on the tractor T2 providing the required auxiliary control signals. The tractor T2 may be arranged to be stopped on receiving a very large signal on coil C2 and a very small signal may be used to start the tractor.

Abstract: 494,672. Cathoderay tubes. MARCONI'S WIRELESS TELEGAPH CO., Ltd. April 26, 1937, No. 11891. Convention date, April 25, 1936. [Class 39 (i)] In a cathode-ray tube using magnetic deflection for scanning, current for producing a deflection in one plane is passed through two or more pairs of coils the current for effecting deflections in the plane at right-angles thereto being passed through the same or another set of coils ; the increased number of coils reduces the distortion of the beam. In one form eight coils 13, Fig. 2, are all on separate polepieces of a core 12 and are in series, the incoming vertical deflection current is supplied by the leads 14, 16 and the horizontal deflection current by the leads 17, 18 the pole markings N, S, at the pole tips corresponding to the horizontal deflection effect. This form of coils may be applied to a core with only four polepieces. In a modification two diametrically opposed pairs of coils 34, 36 and 37, 38, Fig. 3, form the main deflecting coils ; on each of the four polepieces 29, 31, 32, 33 are two independent coils, one of which is used with the vertical, the other the horizontal deflection means. For example coils 39, 41 are in series and in parallel with coils 34, 36 ; these poles 31, 32, 33 act as shading poles and the numbers of windings in the coils in both constructions need not be the same on all the polepieces. The deflection currents are supplied through transformers but the supply for the horizontal deflection may be direct. The windings on some of the poles as shown in Fig. 2 may be reversed.

Title: Electron discharge apparatus
IPC: H01J21/06
Filed: 1940-07-22
Abstract: 543,493. Electron discharge valves. STANDARD TELEPHONES & CABLES, Ltd. July 22, 1940, No. 11999. Convention date, Oct. 6, 1939. [Class 39 (i)] An electron discharge device for use at high frequencies comprises a linear cathode, anode, and auxiliary electrode in spaced parallel relationship and in alignment, the cathode and auxiliary electrode being on opposite sides of the anode, other linear electrodes in spaced parallel relation to the anode and cathode, and a cylindrical electrode surrounding all the linear electrodes, the anode being of such area that it is not completely shadowed from the cathode by intervening electrodes. Figs. 1 and 2 show an oscillation generator comprising a preferably central anode 11, a cathode 13, an auxiliary electrode 14, and a pair of similar output electrodes 15, 16, all surrounded by a braking field electrode 12. The cathode, anode, auxiliary and output electrodes are all of linear form and are mounted parallel to one another and in alignment, the anode 11 and auxiliary electrode 14 being respectively of slightly smaller and substantially the same cross-section as the cathode 13, which is preferably of the equipotential type. In operation, the auxiliary electrode 14 is connected to the cathode, the anode is maintained at a positive potential of the order of 500 volts, and the cylindrical electrode 12 is maintained at a small positive or negative potential with respect to the cathode, or is directly connected to it. Electrons which miss the anode and travel past it are returned by the field of the electrodes 12 and 14 and oscillate about the anode, producing an oscillating current in the output electrodes 15, 16 which are formed with extensions 15a, 16a to form a Lecher system, which is tuned by a sliding contact to the transit time frequency determined by the distance between the electrodes 15, 16 and the anode potential. The electrodes 15, 16 serve as barriers reducing the number of electrons which reach the anode 11, giving a high ratio of displacement to conduction currents. Further, the auxiliary electrode 14 produces electrical symmetry of the electrode structure, so that the anode absorbs practically no high-frequency energy. In a modification each output electrode comprises a number of equally spaced connected elements parallel to and equi-distant from the anode, the elements of the two electrodes alternating. The reduced spacing between the output electrode elements results in a higher frequency of oscillation. Fig. 6 shows the arrangement of electrodes employed in a valve for use as a detector or amplifier, comprising a cathode 118, accelerating anode 130, control electrode 111, anode 115, auxiliary electrode 123, all in alignment and all surrounded by a cylindrical shield electrode. Fig. 7 shows the circuit employed, a Lecher system being employed for the input transformer for ultra-high-frequency.

Title: Fuel injection pump
IPC: F02M59/32
Filed: 1959-04-10
Abstract: 902,009. Fuel injection pumps. BESSIERE, P. E. April 10, 1959 [April 11, 1958], No. 12264/59. Class 102(1). A fuel-injection pump comprises an auxiliary piston 21, Fig. 1, actuated hydraulically on its delivery stroke by the delivery of a main piston 14 driven at a rate proportional to the speed of the engine, the piston 21 delivery fuel in chamber 18b past a non-return valve 19 to the injectors. The end of the delivery stroke of the piston 21 is determined by the opening of a conduit 27 and at approximately the instant at which this piston is arrested a groove 9a of the piston provides a connection between conduits 6 and 4 which allow fuel downstream of the delivery valve to be bypassed and then immediately terminates the injection. A spring loaded valve may be provided in the conduit 4 to ensure that the liquid remaining in the delivery line 20 is at a certain predetermined pressure. During the return stroke of the piston 21 under the action of spring 26 the fuel in the chamber 18a is transferred through a conduit 22 provided with a throttle 23 to the chamber 18b. When the speed of the piston 14 exceeds a predetermined value the piston 21 is prevented from making a full return stroke before it is again actuated by the delivery from the piston 14. A preferable form of the delivery valve is shown in Fig. 3 where the ball valve 19 moves in a cylinder 20a of equal diameter, provided at the top with axial grooves 20b, thus when the valve is closing and the ball has moved past the grooves the liquid in the cylinder 20a is returned by the ball into the chamber 18b. This liquid compensates for the loss in the cylinder 18b due to the piston slightly overrunning the conduit 27 before its movement is arrested and then moving back a small amount during the remainder of the delivery stroke of the piston 14.
