System has an optical sensor (1), an aperture with the optical element (2) with the changeable permeability and an activation light (3) emitting radiation, which is detected by the optical sensor (1). The activation light is connected with the switch (4) and it is placed within the reach of the optical sensor (1). Within a device which realizes the technological process with the luminous manifestation the instruction for the beginning of a given technological process is detected and on the basis of this instruction the activation light (3) lights up. This activates the optical sensor (1) by means of the activation light (3) before the optical sensor (1) detects the luminous manifestation of the technological process itself. The activation light (3) can be a simple infrared LED diode. The advantage lies in the fact that the protective device itself does not have to be modified in any way and its reaction time can be shortened to zero, or negative reaction time can be achieved since we use time passing during the initiation of the technological process before the appearance of the luminous manifestation for the darkening.

The present disclosure provides a stabilizer for a welding gun, wherein said stabilizer may comprise a plurality of sections hinged together to allow rotation with respect to each other and in connection with a user's hand. The stabilizer may comprise a holder designed to accept the end of a welding gun and a positioning device at one end to minimize movement of the welding gun. The stabilizer attaches to the user's hand and allows precise and repeatable welding movements. The stabilizer also allows a user to push fingers slightly, instead of constantly gripping the trigger.

A body cooling apparatus is configured for wear under an outer garment such as those worn by welders. The apparatus is constructed of cloth-covered air tubing which distributes a supply of received compressed air. The user wears the tubing harness much like a vest. When the harness is connected to a compressed air source, the compressed air is vented through the cloth-covered tubing to assist in cooling the user's body.

The present invention relates to welding sleeve preferably comprised of a fabric, leather, or leather-like synthetic material. There is an adjustable, secure means for attaching the welding sleeve to the lower arm of a user or to the upper arm of the user depending upon the relative position of the user compared to that of the materials to be welded. In certain preferred embodiments of the present invention, the fabric may be impregnated with or made from a flame retardant material. Multiple welding sleeves may also be used to protect the upper and lower arms of a user.

Embodiments of a glove including a cut out portion and a reinforcing panel are described herein. In many embodiments, a glove comprises a glove body with a dorsal side, a palmar side, a plurality of finger portions, a thumb portion, and a wrist portion. The wrist portion defines a glove opening in communication with an interior portion defined within the glove body. A reinforcing panel is secured on an outer surface of a palm portion adjacent the wrist portion of the glove body. A cut out portion defines an opening formed through the reinforcing panel and in communication with the interior portion of the glove body to minimize bunching up of the glove body. Other embodiments are also described herein.

Embodiments of golf gloves having a cut out portion and methods to manufacture gloves having a cut out portion are generally described herein. Other embodiments of gloves may be described and claimed.

Described is an upper garment worn by welders while welding overhead, which is made of a breathable fabric and leather. The garment has a hood comprising leather attached to the neckline of the garment body, at least one leather sleeve, and leather on one shoulder and an upper front portion and an upper back portion of the garment that is contiguous with the at least one leather sleeve. The hood may be partially or completely made of leather, and the other sleeve may be leather. The strategic placement of leather on the garment improves the garment's durability, minimizes burns on the wearer from sparks and spatter, and protects the garment from the environment.

A garment related to leg protection for hazardous activities. Darts and pleats sewn or otherwise constructed into such a garment to improve fit and contouring. The garment may comprise a belt assembly providing improved comfort and reduced fatigue and injury with pivot points adjacent a wearer's hips. The belt assembly may have a shape to mimic that of a human pelvis. Such a shape may facilitate the transfer of weight more directly onto the wearer's bone structure with less strain on the wearer's muscles.

In many embodiments, a glove comprises a glove body with a dorsal side, a palmar side, a plurality of finger portions, a thumb portion, and a wrist portion. The wrist portion defines a glove opening in communication with an interior portion defined within the glove body. A reinforcing panel is secured on an outer surface of the glove body between the thumb portion and the wrist portion. A cut out portion defines an opening formed through the reinforcing panel and in communication with the interior portion of the glove body to minimize bunching up of the glove body. Other embodiments of gloves are described herein.
