Title: Pressure modulated brake valve
Inventor: LOHBAUER KENNETH RALPH
IPC: B60T13/14
Filed: 1968-08-13
Abstract: 1,216,897. Brake-pressure reducing-valves. CATERPILLAR TRACTOR CO. 13 Aug., 1968, No. 38611/68. Heading F2F. A valve for controlling fluid pressure to actuate hydraulic brakes comprises a valve having a high-rate-of-flow position and a lowrate-of-flow position, and means operable upon a pressure increase in the brake system between the valve and the brake to move the valve from the high rate to the low rate position, the valve including a spool which is held in the high rate position by a spring and is moved to the low rate position by a plunger actuated by pressure in the brake system between the valve and the brake. As shown in Fig. 1, a pump 10 delivers hydraulic fluid from a reservoir through an accumulator charging valve 12 to other circuits at 14 and to an accumulator 16 and to a valve 20 at 18. The valve 20 has an outlet 22 to the brakes and an outlet 24 to a sump (see also Fig. 2). The hydraulic pressure between the valve and the brakes is conveyed, within the valve, from outlet 22, at 52 to the right-hand end of a plunger 54, and at 56 to the left-hand end of a plunger 58. A brake pedal acts through a link 36 and lever 38, Fig. 1, on a shaft 40 provided with a fork 42, Fig. 2, fitting in a groove in a rod 44. In operation, when the brake pedal is depressed, the rod 44 is moved to the right from the position shown and acts through springs 46, a cup 66, and a spring 48 (unyielding at this stage) to move a valve spool 26 to the right against the force of a spring 50 until cup 66 makes contact with the housing. The spool 26 is then in a position where communication with sump outlet 24 is closed, and inlet 18 communicates with brake outlet 22 through the short wide parts of slots 30 which traverse a shoulder on the spool: this is the " high rate of flow "  position. As the pressure at outlet 22 increases, but before it has reached its maximum, the pressure acting on plunger 54 is sufficient to move spool 26 to the left, overcoming the force of spring 48 only, until the gap 70 between spool 26 and cup 66 is closed. In this position of the spool, outlet 24 is still closed, and inlet 18 communicates with brake outlet 22 through only the longer narrower parts of the slots 30: this is the " low rate of flow " position.

Title: Improvements in or relating to picture tube arrangements for three-colour televisionsystems
IPC: H04N9/285
Filed: 1958-12-09
Abstract: 840,079. Electron lenses. PHILIPS ELECTRICAL INDUSTRIES Ltd. Dec. 9, 1958 [Dec. 11, 1957], No. 39670/58. Class 39(1). In a 3-colour television picture tube comprising three guns arranged at the corners of a triangle, astigmatism and coma are reduced by making the meridional image plane for the direction of deflection which is parallel to the plane containing two of the guns, and the sagittal image plane for the other direction of deflection, both coincident with the screen. The tube referred to is of the mask type. The coils of the Y and X deflection systems are pairs of asymmetrical half coils, as shown in Figs. 2 and 4, producing the variation of the magnetic field HI2 and HII2 in the Z direction shown in Figs. 3 and 5 respectively. The theory for the correction of the errors and the design of the coils is given in the Specification. In Fig. 6, the deflection system consists of two ferromagnetic cores 11, 12 each with eight toroidal coils. The X deflection system consists of four coils on core 11 (only two, 13 and 14 shown), and four coils on core 12 (only two, 17 and 18 shown), coil 21 and 22 are two of the four Y deflection coils on core 11 and coils 25 and 26 are two of the four Y deflections coils on core 12. The angles subtended by the coil pairs are 25 degrees and 43 degrees for the X coils and 33 degrees and 20 degrees for the Y coils. The eight coils in each set may be connected as shown in Fig. 9 or Fig. 10, the circuit including a variable inductance 30, Fig. 9, or 34, Fig. 10. Dynamic convergency is exerted on the beam produced by the gun outside the plane containing the other two guns to ensure that this beam is superimposed on the other two beams throughout the deflection. For this purpose currents proportional to the squares of the currents for producing the X and Y deflections are passed through an additional set of deflections. Where the X and Y deflection currents are sawtooth, these additional currents may be parabolic currents of line and raster frequencies. Dynamic convergency may also be applied to the beams from the two guns in the same plane for complete correction of the deflection errors.

Abstract: 1324417 Semi-conductor devices MATSUSHITA ELECTRIC INDUSTRIAL CO Ltd 20 Aug 1970 [21 Aug 1969] 40146/70 Heading H1K A current switching element comprises a disc body composed of finely divided conductive particles disposed in a synthetic resin (Fig. 4, not shown), with electrodes disposed on opposite or on the same sides (Figs. 1, 2, not shown), having a high and a low resistance state, wherein increasing voltage is applied to the device in its high resistance state (Fig. 3) and current increases ohmically until a critical value is reached. The device then changes over to a low resistance state and current again increases ohmically with voltage. Reduction of voltage to point 21 causes changeover to the high resistance state and further reduction of voltage produces ohmic reduction of current to zero. The cycle may be repeated, and the device may receive a bias less than the first and greater than the second critical voltage so that a pulse of amplitude exceeding the first critical voltage initiates rapid changeover to the low resistance state until a similar negative pulse produces restoration of the high resistance state. The composition of the element is similar to that of Specification 1,324,416.
