Abstract: A protective lens assembly includes a protective lens, such as an auto-darkening lens, having a first viewing portion and a second viewing portion. One of the first or second viewing portions includes a magnifier plate, allowing the viewer to view magnified images through one of the first or second viewing portions and unmagnified images through the other of the first or second viewing portions. The lens assembly allows the viewer to perform close-up tasks and other tasks without having to reconfigure the lens assembly between tasks.

Abstract: An electrical interconnection device including an electrical element and a sealing member sealed within a body. The body is constructed of a first section and a second section bonded together to form an enclosure for retaining the electrical element and sealing member. Sealed passageways extend from the sealing member to the electrical element. Substrates are inserted through the sealing member into the passageways for connection to the electrical element.

Abstract: An insertion tool for inserting substrates having contacts disposed at their distal ends into a connection device and a method of use. The tool of the present invention is useful with any size substrate and contact, but is particularly useful for wires or fiber optic cable having small diameters with insufficient rigidity to withstand the connection force required to insert the contact into the connection device. The tool includes a pusher arm which engages the contact and forces the contact into the connection device. As the contact is inserted, the pusher arm is also inserted into the connection device and is subsequently removed from the connection device.

Abstract: A medical terminal clip is disclosed, particularly for use in connecting a lead wire or conductor to an electrode conventionally secured to the skin surface of a human or animal. The electrode comprises a male projection of the buttontype with an enlarged diameter head portion disposed within a recessed area of the electrode. The clip is generally V or wishbone shaped and includes a pair of support arms secured together at one end and normally spaced from each other at the other end. The arms carry resilient conductive loops normally biased out of overlapping condition but movable upon the application of external force into an overlapped condition wherein the clip may be applied over the head portion of the electrode. The support arms have offset depending shoulder portions from which the conductive loops extend and which are positionable within the recessed area of the electrode when the arms are moved toward each other.

Abstract: A feed-through connector is disclosed which allows the interconnection of adjoining electrical circuit modules, such as prewired wall panels, in any one of a variety of angular orientations. The feed-through connector is extremely simple in construction which facilitates its fabrication and assembly and minimizes its cost of manufacture. In addition, it can be conveniently incorporated into the vertical support members used in portable wall structures in such a manner as to increase the number of panels which may be assembled to a single support member and to optimize the variety of configurations in which the panels may be disposed. The connector includes a dielectric housing having at least one recess around its periphery and at least one conductive plate mounted within the recess, the recess and plate together forming a connector receptacle. The recess provides access to the conductive plate such that the contact elements of at least two modules can electrically engage the conductive plate.

Abstract: An identification means is disclosed for use with lead wires of electrocardiographic monitoring instruments or the like. The identification means includes a terminal body member secured at one end of a lead wire and has a peripheral recess extending substantially thereabout. An identification member having identifying means corresponding to one of a plurality of commonly recorded anatomical positions is positionable onto the terminal body member and has an interior lip snap fit within the recess of the terminal body member to retain the identification member onto the terminal body member and prevent unintentional removal therefrom. The identifying means on the identification member comprises raised indicia and is color coded to the anatomical positions. The identification member exclusive of the raised indicia also is color coded to different color codifications than the raised indicia. A plurality of identification members are provided, each comprising one of a set thereof of differently color coded members.
