  • Patent number: 4041366
    Abstract: A voltage multiplier device is disclosed in which the capacitors are arranged and formed in a hollow cylindrical shape and the diodes are interconnected in a zigzag pattern along the outer circumference of the tubular capacitor roll. The device of this invention has particular use for generating the beam acceleration voltage in television picture tubes. The interior of the tubular capacitor roll has space and mounting means associated therewith which permit the device to be mounted on one arm of the magnetic core of a line transformer. The entire device, with the exception of the terminals and connector elements, are built into an insulated casing which is sealed with a sealing compound or formed into the shape of the block with the aid of a casting resin.

  • Patent number: 4029378
    Abstract: The electrified channel and corresponding snap acting connector of this invention provides for aligned conductors, preferably in the form of bus bars, secured to an insulation body carried by a channel. A mating or corresponding connector includes elastically mounted contacts carried in a housing which has a pair of spring elements on its exterior designed to retain the connector body with the contacts making contact with the conductors. When the contacts are in contact with the conductors they are spring pressed against them. A pair of external shoulder members, which are external to the channel when the connector is in place, can be moved inwardly to engage the spring clips thus permitting the connector to be removed from the channel with the spring pressure on the contacts assisting withdrawal of the connector from the channel.

  • Patent number: 4025123
    Abstract: The brake force regulator of this invention provides for genuine dual circuit control so that in the event of failure of one of the intact brake circuits, control of the other can be continued at an increased switching point pressure. The brake force regulator of this invention includes a pair of axially displaceable stepped pistons which make fluid connections to both brake circuits in the same manner. A control chamber is defined by both stepped pistons on the one hand and a control piston to which is applied to control force on the other. A fluid connection is provided between thecontrol chamber and the brake circuit controlled by each stepped piston which is opened when the control piston approaches either of the stepped pistons. The faces of the stepped pistons to which is applied the pressure in the control chamber is smaller than the face of the control piston upon which the pressure in the control chamber acts in the opposite direction.

  • Patent number: 4022929
    Abstract: The invention relates to a method of aluminizing the inside of the panel of a television picture tube. When aluminizing the inside of the panel, blisters caused by the vaporizing lacquer, are likely to develop in the layer of aluminum, especially on the side walls of the panel portion. When taking care in accordance with the invention, that the coat of lacquer is roughened prior to the performance of the aluminizing process, these blisters are avoided.

  • Patent number: 4017149
    Abstract: A multiple access fiber optical bus system having superior features as compared to the prior art is provided in which single fibers may be used as transmission lines in a closed loop system. A plurality of optical transmission mixers are provided, each of which mixes the inputs from one or more transmission lines to provide outputs to a multiplicity of transmission lines. Each of the mixers independently operates a plurality of transmission lines. Various degrees of reliability terminals are provided. A high reliability terminal has inputs from and outputs to the last one of the transmission lines on the output side of each of the independent mixers. A low reliability terminal has connections to only one of the independent mixers transmission lines. Any degree of reliability between the lowest and highest can be obtained depending upon the number of independent mixer loops to which such a terminal is connected.

  • Patent number: 4015225
    Abstract: An encapsulated electromechanical relay provides both make and break contact functions by utilizing a movable diaphragm for connecting between inner and outer concentric conductors. In a non-energized state the diaphragm provides electrical continuity between one pair of contact members, and in a magnetically energized state the movable diaphragm contact then povides electrical continuity between a second pair of contact members by moving away from the central contact of the first pair and moving into contact with the central contact of the second pair.

  • Patent number: 4004839
    Abstract: The brake force regulator device is for a dual circuit brake system in which the function of the regulator is suppressed if an uncontrolled brake circuit fails. A locking piston is provided which serves this purpose as well as at the same time to release a differential pressure warning signal should one of the two circuits fail. The advantages achieved with the arrangement disclosed are that only a small amount of pressure fluid is drawn from the intact brake circuit in case of the failure of the other circuit so that the locking piston performs a dual function.

  • Patent number: 4004122
    Abstract: A microwave heating oven has a microwave-shielded loading passage and a first heating zone for containing the material in solid form. A second heating zone maintains the material in its liquid state and provides an exit passage for removing the material while in its liquid state. The oven finds particular application in the processing of materials for photographic emulsions where the emulsion material is placed in the first heating zone in solid form. The second heating zone is located directly under the first and is separated from the first by a perforated partition. Subjecting both heating zones to microwave radiation causes the solid emulsion material in the first zone to melt and to pass through the perforated partition to the second zone where the emulsion material is removed as a liquid.

  • Patent number: 4001727
    Abstract: Control of the gate electrode of a magnetic-beam-triode oscillator is effected by a diode connected between the gate and a controllable shunt regulator. The regulator is varied by a voltage derived from a differential amplifier forming part of a closed loop feedback circuit including the oscillator. By introducing an additional differential amplifier, variation of the regulator may also be made to depend on one of several parameters of the oscillator and load circuit, for example on the r.f. tank circuit voltage.

  • Patent number: 3997841
    Abstract: If a time domain equalizer with capacitive-resistive voltage dividers for adjusting the level of the individual time-delayed partial signals as commonly employed for high frequencies is to be used to equalize broad communication bands, the noise requirements for the lower communication band cannot be satisfied because of the frequency response of the voltage dividers. This effect is reduced by adding to the signal to be corrected, besides the signals delayed by n..tau., at least one signal delayed by .tau./m.

  • Patent number: 3992621
    Abstract: A vacuum tube photodetector includes a planar photocathode, a parallel high voltage accelerating mesh, and a planar output anode positioned adjacent to and spaced from the mesh. The anode and mesh are connected to the inner and outer concentric conductors of a high frequency coaxial transmission line coupled to a load or output device. The high voltage preacceleration of electrons by the mesh and the small mesh to anode spacing provide a significant reduction of electron transit or pulse rise time compared with known two element biplanar photodiodes. In addition, the vacuum seal between the anode and mesh is positioned adjacent the anode-mesh gap which greatly reduces pulse decay time and undesired reflections. The mesh and anode are at the same potential to eliminate the usual high bias voltage between inner and outer coaxial photocathode and anode electrodes of the biplanar tube, as well as a coaxial coupling capacitor.
