Within a welding helmet, an easily removable electronic quick change ('EQC') cartridge is retained into an integral cartridge housing. The EQC cartridge has slots on its top which can accommodate flanges from the housing, and tabs on its sides for insertion into slots of the housing. The tabs are located on the ends of an elastic spring bar which is inside the EQC cartridge. Switches connected to the spring bar by an elevated support lie above the EQC cartridge, which when compressed internalize the tabs inside the cartridge. When the EQC cartridge is positioned within the housing, the switches are released and the tabs extend through the slots of the housing.

Welding helmet with removable electronic quick change cartridge

A safety spectacle providing front and lateral impact protection. The spectacle includes a frame, a removable lens incorporating integrated upper and lower side shields connected to the frame by means of a nose bridge, and a pair of length and pantoscopic adjustable temples arm assemblies hingedly connected to the sides of the frames. The temple arm assemblies are adjustable lengthwise by earpieces which can be locked and unlocked into slots on an intermediate arm receptacle by means of a quarter turn barrel configuration. The temples are adjustable pantoscopically by means of a pair of semicircular arms, both of which are hinged at the front to the side of the frame between a pair of outward sloping walls and inserted at the rear into a threaded ferrule. One arm is threaded inside the ferrule and allowed to move in and out when the ferrule is rotated while the mating semicircular arm is stationary, thereby varying the angle of the temple within the sloped walls and thus the frame.
