Abstract: A multiple wire joining device is disclosed which includes a generally tubular, deformable, electrically conductive housing having multiple apertures formed in the wall thereof. The apertures are axially spaced apart along the length of the housing and are each adapted to admit a wire therethrough so that it may entend axially along a length of the housing. The spacings between the apertures are sufficient to permit the admittance of a wire into the housing through each of the apertures a sufficient distance to enable the crimping of the housing adjacent each aperture to retain the respective wire therein.

Abstract: An electronic actuator having an armature movable between the legs of a u-shaped structure of magnetic material and guided by a sleeve of non-magnetic material which is held in place by an annular member of the magnetic material. A permanent magnet is located between the legs and is secured between the magnetic structure and the annular member to form a magnetic path through the parts and to magnetically latch the armature in either of two positions. Electromagnetic coils are mounted on the sleeve on opposite sides of the annular member to selectively drive the armature to either of such positions.

Abstract: A balanced valve in which a hollow cylindrical valve element is slideably supported solely by a pair of O-rings adjacent opposite ends of the valve element. The O-rings loosely engage longitudinally grooved sections which are directly adjacent annular valve seats against which the O-rings engage to close the valve. When the valve element is moved to open the valve, fluid will flow through both grooved sections. The valve element is moved between open and closed positions by two solenoid coils operating concurrently and is magnetically latched in each position.

Abstract: A moisture proof switch in which an elastomeric O-ring is interposed between a push button and a switch housing. The O-ring is normally held in partial compression to prevent entrance of moisture, etc. into the housing and to normally hold a switch contact member out of engagement with contacts carried by the housing. Depression of the push button further compresses the O-ring to close the switch.

Abstract: A frame type electrical socket for connecting leadless integrated circuit packages to a printed circuit board is disclosed. The socket includes a rectangular frame member and four contact assemblies. Each contact assembly is designed to detachably mate with each side of the frame. The contact assemblies include molded-in-place contacts which are shaped to provide pressure contacts after they are molded in place. Prior to molding, the contacts are in the form of flat ribbons, allowing them to be constructed in the form of a lead frame. The socket possesses all of the features of molded-in-place contacts as well as having the advantage of being able to replace damaged contacts without discarding the frame.

Abstract: An electrical connector for effecting connection to leadless integrated circuit packages without the use of printed circuit boards is disclosed. A first embodiment is used to provide electrical connection from electrically conductive pads on one package to the respective pads on another package by means of a series of resilient electrically conductive contacts supported in a generally T-shaped dielectric body which is inserted between adjacent packages. A second embodiment is also disclosed which may be used to connect a leadless integrated circuit package to a multiconductor cable without the use of printed circuit boards.

Abstract: An electrical switch is disclosed which includes a first and second pair of pole pieces and an armature mounted to move freely between the first pair of pole pieces and the second pair of pole pieces. A magnet is provided which is supported for movement between the first pair of pole pieces and the second pair of pole pieces. When the magnet is moved from one position to the other, the flux is switched from one pair of pole pieces to the other pair of pole pieces and the armature moves from one pair of pole pieces to the other pair of pole pieces.
