Abstract:
An improved construction for a miniature vacuum relay is provided, whereby the relay is capable of a latching operation. The relay responds to an electric pulse of a first polarity to move from one electrical switching condition to another, and it remains in the second electrical switching position until a second pulse of opposite polarity is applied to the relay, at which time the relay returns to its original switching position. A permanent magnet is included in the magnetic circuit of the relay so that when the armature is moved against the action of the biasing spring of the relay to a particular position, it is retained in that position by the permanent magnet until an opposing magnetic flux is created in the magnetic circuit to nullify the action of the permanent magnet.
Abstract:
A high voltage relay is provided in which the operating components of the relay are enclosed in a sealed envelope which may be evacuated. The relay to be described is a miniaturized high voltage relay capable, for example, of operating at voltages up to 5 kilo-volts, and in conjunction with relatively high frequencies. The envelope of the relay is composed of ceramic, and the relay is capable of efficient operation in wide extremes of ambient temperatures. The relay includes a linearly movable contact which makes connection with a fixed common electrical terminal through a resilient diaphragm which is constructed to permit free linear reciprocal movement of the movable contact and yet maintain a positive electric current to the common terminal.
Abstract:
An improved high voltage vacuum relay is provided which includes internal shielding means which serves to prevent ionic discharge within the relay from the high voltage contacts thereof to its grounded magnetic actuating circuit, and which also serves to strengthen the bulb and to make the unit less susceptible to breakage.
Abstract:
A high-voltage relay is provided in which the operating components of the relay are enclosed in a sealed envelope which may be evacuated, for example, or filled with a pressurized dielectric gas. The relay is constructed to include an elongated envelope formed of glass, or other vitreous or electrically insulating material, and which has electrical terminals extending through the envelope at the side of the envelope and at one end, so as to provide good insulation from the grounded electromagnetic actuating components at the other end of the relay, in order that the relay may be operated at high voltages.
Abstract:
A high-voltage, high-vacuum X-ray tube is provided which includes a rotating target electrode for increased target life, and which also includes a unique and improved electric motor for rotatably driving the target electrode, the motor having a flat, ''''pancake'''' configuration, with a rotor inside the evacuated envelope of the X-ray tube, and with an externally positioned stator.
Abstract:
A high-voltage vacuum relay is provided of the double-pole, double-throw type and which has particular application to medical purposes, although it is not limited to uses. The movable and fixed contacts of the relay are mounted with an envelope, with the movable contacts supported by the envelope for pivotal movement, and for selective engagement with the fixed contacts in a manner such that under no conditions will one contact of any pair open without the other.
