| A reed relay includes a reed switch with contacts, and a pair of terminals connected to the contacts. A tubular electrostatic shield defines an axially extending central bore within which the reed relay is inserted. A coil assembly has a winding drum, and a coil provided on the winding drum. The winding drum defines an axially extending central bore within which the electrostatic shield is inserted with the reed switch. A first pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A second pair of leads extend oppositely to each other, and are connected to the electrostatic shield at the opposite ends of the coil assembly. A third pair of leads extend oppositely to each other, and are connected to the coil at the opposite ends of the coil assembly. A fourth pair of leads extend oppositely to each other, and are connected to the terminal of the reed switch at the opposite ends of the coil assembly.

| An electromechanical switch including a non-magnetic cup shaped housing, the interior of which is sealed from the atmosphere with a seal assembly. A first electric terminal extends through the seal assembly and is connected to a coil spring. A second terminal includes a stationary electrode. The electrode extends through the seal assembly and through the coil spring. The coil spring supports a movable contact. A permanent magnet is selectively movable via a solenoid in close proximity to the contact member for selectively moving the contact member in and out of contact with electrode. In the closed position, electric current flows between the first and second terminals and through the coil spring. In another embodiment, an electric magnet provides the necessary flux for selectively moving the contact member. In yet another embodiment, two electrodes extend through the seal assembly and the movable contact is selectively placed in and out of contact with both of the electrodes for selectively controlling electric current flow between the terminals. The coil spring is preferably made of beryllium copper and the movable contact and electrodes are made of molybdenum. The interior of the non-magnetic housing can be evacuated placing it in a vacuum or filled with an arc quenching gas. | ||||||

| A sealed relay of the high-vacuum type, or which may be backfilled with a dielectric gas such as hydrogen-nitrogen mixture for improved arc suppression when switching high-voltage d-c currents. The relay uses controlled fixed contacts which enable use of a reduced-diameter disk-shaped movable contact. Thus permitting optimal placement of external arc-supporting permanent magnets on a ceramic relay housing in close proximity to the enclosed fixed and movable contacts. A staggered or offset positioning of the fixed contacts makes the relay polarity insensitive for bidirectional switching of high-voltage d-c currents. | ||||||

| A switch assembly comprising a housing including a baseplate on which are mounted a magnetic core having a pair of flanges and a winding wound around it, and two switch capsules positioned on either sides of the magnetic core with each capsule being insulated from each flange of the magnetic core by insulating means. Magnets are also positioned to provide either a monostable or a bistable mode of operation as desired. With this constructions, the magnetic and electric paths in the assembly are physically separate from one another, thereby allowing the magnetic and electric materials to be chosen independently from each other. | ||||||

| A relay device utilizing a linear "impact break" method for contact break. An armature shaft has attached at one end a plunger situated at the base of the relay core. The armature has a terminal end portion at its other end. A spring provides a biasing force to maintain the plunger and armature shaft in open state. Resiliently mounted on the armature shaft adjacent its end opposite the plunger is a movable contact disc rotatable about the armature shaft for coming in contact with two stationary contacts in the closed state. The armature shaft towards its plunger end extends into an armature travel cavity. The armature shaft towards its movable contact end extends into a chamber open to the armature travel cavity. A movably mounted further spring is located about the armature shaft between the contact disc and a stop on the armature shaft. The further spring rotates upon its compression to rotate the contact disc to vary the position of contact during a plurality of closing operations. The terminal end portion extends beyond the contact disc upon closed state, and is accelerated by expansion of the further spring to impact the contact disc to provide the contacts open state. All moving parts of the relay are hermetically sealed from the outside atmosphere. | ||||||

| A relay features two base-structured components (1 & 2) in the shape of half of a bowl having a winding (3) mounted on it. Two pole plates (6 & 7) are embedded in a common plane in one (2) of the base-structural components. The ends of the pole plates extend into a contact space (4 & 5). Paralleling the pole plates inside the contact space is a bridge armature (8) that is secured to a frame-shaped spring (9) in a plane coextensive with the separation between the two jointed base-structural components. The connection elements extend out of the sides of the base structure in the spool flanges and are bent down. | ||||||

| A measuring apparatus employing hard X-rays comprises a pair of sensors receiving substantially simultaneously hard X-ray beam emitted from an X-ray source, one of which sensors receives the beam directly from the source and not passed through an object to be measured while the other sensor receives the beam passed through the object. The other sensor comprises an X-ray image receiving camera providing an X-ray image of the object and a spot X-ray sensor for receiving the beam passed through a restricted measuring zone or spot in the object, and the camera and spot sensor are shiftable alternately to a position of receiving the beam passed through the object, whereby, after visual observation of the X-ray image for discrimination, the restricted zone or spot can be determined for a higher precision measuring, and a precise quantitative measurement can be carried out by the spot sensor with respect to the restricted zone or spot. | ||||||

| A symmetrical bobbin especially adapted for the automatic manufacture of electrical coils. The bobbin, formed of high-strength plastic material, comprises first and second lips formed at terminal ends thereof and first and second flanges spaced inwardly from the lips. The bobbin surface between the flanges defines a main coil winding space and the bobbin surfaces between the lips and corresponding flanges define first and second terminal winding spaces. Immersion soldered terminal connections, of high physical strength, durability and electrical conductivity, are formed by extensibly wrapping electrical wire from the main coil about the terminal winding spaces and subsequently immersing the wire-wound terminal winding spaces in molten solder to provide a circumferential bond of unitary structure for terminal connection. | ||||||

| A multi-positional mercury switch (1, 2, 3) for use with miniature relays (4). The mercury switch apparatus has mercury wettable magnetic contact structures (11, 12, 211, 212, 221, 222, 311, 312) supported in a sealed envelope member (10, 20, 30) supporting the magnetic contact structures with ends thereof extending from the envelope member for interconnection with terminals of the relay. A mercury holding assembly (13, 14, 23, 24, 33, 34) is slidably located within the sealed envelope member adjacent the magnetic contact structures and is responsive to an external magnetic field generated by electrical signals in a coil (410) surrounding the sealed envelope member for engaging the magnetic contact structures and establishing an electrical conducting path between the magnetic contact structures. | ||||||
