A connector system for connecting a cable having a length to an item includes a base operatively connectible to the item, the base including a channel to seat at least a portion of the cable, the channel being in operative connection with the item upon connection of the base to the item, and a rotatable member which is rotatable relative to the base. The cable is in operative connection with the rotatable member so that, as the rotating member rotates relative to the base, a bend in the cable is formed at different locations in the length of the cable such that the different locations define different lengths of the cable. The different lengths of the cable become positioned within the channel as the rotating member rotates relative to the base.

Cable connector for use with a rotating connection

An indicator arrangement for a regulator removably connectable to a facemask in a breathing apparatus, the indicator arrangement including: at least one release button comprising a body operationally engaged with at least one component of the regulator and configured to be actuated by a user to detach the regulator from the facemask, wherein at least a portion of the body is configured to facilitate transmission of light from at least one light source; and wherein the light is visible on or through at least one external surface of the body of the at least one release button. A regulator release button and breathing apparatus are also disclosed.

Indicator arrangement, regulator release button, and breathing apparatus

A respirator system includes a regulator for use in connection with a facepiece of the respirator system. The regulator includes an interface. The respirator system further includes a hose assembly including a hose for carrying breathing gas to the regulator and a cable for carrying at least one electrical wire to the regulator. The respirator system also includes a connector system. The connector system includes a base operatively connectible to the interface of the regulator. The base includes a channel to seat at least a portion of the cable. The channel is in operative connection with an interior of the regulator upon connection of the base to the interface. The connector system also includes a rotatable member which is rotatable relative to the base. The cable is in operative connection with the rotatable member so that a bend in the cable travels along the length of the cable and a varying length of the cable is positioned within the channel depending upon the rotational position of the rotating member relative to the base.

The present invention provides an air-purifying respirator facepiece with a removable, one-piece filter element connector. It also has a removable component housing in the lens as well as a nosecup without inhalation valves that prevents fogging of the portion of the lens used for viewing.
