Abstract: An attachment which converts a single station, spring powered, temperature sensitive, fire alarm protection device into a remote signalling heat detector for a central fire alarm system, without affecting the internal apparatus of the alarm device or the environmental protection of such internal apparatus. The attachment includes a pivotally mounted member having a shield arm interposed between a magnet and a reed switch, and a lever arm which interacts with a winding key on the alarm device to move the shield arm from between the magnet and reed switch when the alarm is actuated. This movement of the shield arm permits the magnetic force of the magnet to activate the reed switch. The reed switch is connected by wire or radio link to a central monitor. Actuation of the reed switch, in response to actuation of the alarm device, produces an alarm signal at the central monitor.

The glove has a thumb stall disposed generally behind the thumb portion of the body, at least one finger stall disposed generally behind the finger portion of the body, a crotch portion between the thumb and finger stalls, a palm portion, and a hand-receiving opening adjacent the bottom of the mitt. The glove is joined to the mitt body at the periphery of the hand-receiving opening and at the ends of the thumb and finger stalls, but is free of attachment to the body at its palm portion, thereby providing freedom of movement of the palm portion of the glove relative to the mitt body for increasing the flexibility of the mitt.

Abstract: A pressure demand breathing apparatus having a facemask connected through a pressure demand regulator with a shut-off device that operates automatically to interrupt the supply of air to the mask when the facemask is removed. The device operates with a time delay to permit momentary user-induced high flow rates without interrupting the supply.

Abstract: A face mask is connected to a source of breathing fluid through a pressure-demand regulator and a supply line. The regulator admits breathing fluid to the mask on demand and maintains a positive pressure within the mask at all times to prevent inflow from the surrounding atmosphere. The regulator has a flow capacity considerably greater than that normally required, even when gasping or breathing heavily. An automatic shut-off device in the supply line upstream of the regulator permits the peak flow of a predetermined breathing requirement but is responsive to abnormal flow conditions, as for example where the mask is removed from the wearer, to close the supply line and thereby prevent wasting of the air breathing fluid supply. The apparatus can be manually reset to normal operation and will reset itself after the mask is repositioned on the wearer.
