Abstract:
A jack assembly for use with a modular electrical plug includes a jack housing. The jack housing includes an electrically non-conductive substrate metalized with a metal shield layer. The jack housing defines a socket adapted to receive the plug. At least one electrical contact is positioned in the socket to engage the plug when the plug is inserted in the socket. An electrically conductive jumper member including a drain wire connector may be mounted on the jack housing. The drain wire connector includes a pair of connector tabs defining a slot therebetween to receive and hold the drain wire.
Abstract:
A process for reducing the sulfur concentration in a fluid, such as a hydrocarbon gas stream is disclosed. The process comprises contacting the fluid with an aqueous alkali metal hydroxide solution and subsequently contacting the resulting liquid effluent with carbon dioxide to form an aqueous alkali metal carbonate salt solution and a volatile sulfur compound. The aqueous alkali metal carbonate salt solution is passed into an electrolytic cell wherein the alkali metal salt is converted to alkali metal hydroxide.
Abstract:
A communication jack connector includes a wiring board having a front region, and a number of contact wires for engaging and making electrical connections with corresponding terminals of a conforming plug connector. The contact wires have free ends formed to be deflected resiliently in a direction toward the front region of the wiring board when engaging the plug connector. At least one clearance opening is formed in the wiring board at a location where the free end of a corresponding contact wire would otherwise contact an upper surface of the board when deflected by the plug connector. The clearance opening is dimensioned so that part of the free end of the contact wire deflects into the opening a certain distance from the upper surface of wiring board while the contact wire maintains sufficient resilient force to connect electrically with the corresponding terminal of the plug connector.
Abstract:
A coin chute includes a coin entrance, clear-out apparatus, coin processing apparatus, a return chute and a coin ejector. The clear-out apparatus is positioned between the coin entrance and the coin processing apparatus. It comprises a cavity for trapping unwanted material stuffed into the coin entrance and a pair of sidewalls (inner and outer) that move in response to the operation of the coin ejector. A deflector plate, positioned within the cavity, assists in trapping the unwanted material. The outer sidewall permits trapped material to fall into the return chute while the inner sidewall pushes this material into the return chute. The coin ejector includes an actuator that is operatively connected to the sidewalls of the clear-out apparatus by a helical spring whose restorative force is sufficient to urge material trapped within the cavity into the return chute, but not sufficient to damage the coin ejector when excessive force is applied to the actuator.

Abstract:
In accordance with the invention, there is provided a telecommunication jack that is free of cross-over sections, has cross-talk characteristics that approach Category 6 levels, and avoids the use of spring contact wires supported in a cantilevered fashion. This is achieved in a preferred implementation by spring terminal contact wires that are arch shaped. Each spring wire has a first leg having an end, a second leg having an end and an apex portion located between the first and second legs where the ends of the legs are supported on a wire board and each end makes electrical contact with separate conductive pads. When utilized in an operating circuit, one end and leg of a spring terminal contact wire is coupled to a conductive pad on the wire board that is in a current carrying signal path, and the other end and leg of that spring terminal contact wire is coupled to a different conductive pad on the wire board adapted for connection to a cross-talk compensating component. In accordance with the invention, both pads of the wire board are connected to a common spring terminal contact wire, although only one pad and one leg of the arch shaped spring wire may be in the current carrying signal path. The legs of the arch shaped spring terminal contact wires can be of equal or unequal length, the arch can be semi-circular, triangular or the like, and the conductive pads on the wire board of adjacent spring wire terminals can be either aligned or staggered in distance from the edge of the wire board.
