An omni-directional connection assembly broadly includes a hinge pin and one or more connection brackets. The hinge pin comprises a base section, a pair of primary walls, and a pair of opposed projections. The primary walls form a primary slot therebetween for receiving an engagement portion of a first panel therein. The opposed projections are spaced from the primary walls and form elongated passageways for allowing the primary walls to bend slightly outward for receiving the engagement portion of the first panel. The connection brackets are U-shaped for being positioned over the hinge pin and including flanges for attaching the connection brackets to a second panel. The first and second panels are then connected together at angles of between 0 and 180 degrees or more.

A substantially vertically extending removable and replaceable cover and a substantially horizontally extending cover for use with a curtain wall system broadly comprising an array of windows, a set of vertical and horizontal mullions, a set of window gaskets. The covers overlay the mullions and each include a front side, left and right or top and bottom sides, and rear tabs extending therefrom for removably connecting the covers on the mullions.

A mask and harness system for use in providing breathing oxygen and protection from pollutants for the eyes and respiratory system includes a face seal, a soft flexible lens, a pneumatically-actuated harness, and a regulator with microphone to control the flow of oxygen and to facilitate communications in aircraft flight decks and other aircraft compartments.

A mask and harness system for use in providing breathing oxygen and protection from pollutants for the eyes and respiratory system as might be encountered in high altitude aviation environments. In one preferred embodiment, the mask system has a face seal, a soft flexible lens, a pneumatically-actuated harness, and a regulator with microphone to control the flow of oxygen and to facilitate communications in aircraft flight decks and other aircraft compartments. The system is designed for required five-second donning with one hand and because of the flexible lens, is capable of storage in the relatively preferred on crowded flight decks. It is connected to an oxygen source and, optionally, with aircraft communications. The regulator controls the flow rate of oxygen to the wearer based on altitude and physiological requirements. The regulator includes a valve for purging the condensation-prone moist gases from the lens area and provides positive pressure in the mask. A second preferred embodiment molds the lens and mask seal of a single material having sufficient optical quality and flexibility to accomplish both purposes.

A microphone signal attenuating breathing mask body having a gas port for inhalation of a gas to the wearer in a flow stream therethrough. A demand microphone is mounted to the mask and is coupled to an electromagnetic switch responsive to a predetermined magnetic field for switching from an actuation to an attenuation position to block transmission of sound from the microphone. An air vane is pivotally mounted on the mask body and is formed with an impingement pad positioned in the flow stream and mounts an activating magnet disposed adjacent the switch. The vane is normally disposed in a normal position such that the magnet is in an activating position and the electromagnetic switch is in the actuation position such that the microphone is active for transmission of audio signals. Upon inhalation by the wearer, the vane is responsive to the impingement of the air stream on the impingement pad to move the vane to a displaced position moving the magnet to the deactivating position, switching the switch to the attenuation position to block transmission of audio signals from the microphone.
