A loose fitting respirator hood made of flaccid, non-stretchable, air impervious material with a curved optical lens panel interposed in the sidewall thereof. The method of making the hood is disclosed in which curvature is imparted to a relatively stiff lens panel by the flaccid material of the hood. Head engaging members are disclosed for supporting the hood on the head of the wearer. A neck engaging ruff is disclosed which is sealingly mounted about the interior of the hood and can define a hollow annulus with apetures through the sidewall thereof to provide for air distribution to the interior of the hood. A rigid collar member for interconnecting the hood with a suit is disclosed together with the provision of an air filter in communication with a tubular member sealed through the lens panel and extending into proximity with the mouth of the wearer to supply respirable air.

Method of making loose fitting supplied air respiration hood

A loose fitting respirator hood made of flaccid, non-stretchable, air impervious material with a curved optical lens panel interposed in the sidewall thereof. The method of making the hood is disclosed in which curvature is imparted to a relatively stiff lens panel by the flaccid material of the hood. Head engaging members are disclosed for supporting the hood on the head of the wearer. A neck engaging ruff is disclosed which is sealingly mounted about the interior of the hood and can define a hollow annulus with apertures through the sidewall thereof to provide for air distribution to the interior of the hood. A rigid collar member for interconnecting the hood with a suit is disclosed together with the provision of an air filter in communication with a tubular member sealed through the lens panel and extending into proximity with the mouth of the wearer to supply respirable air.

Loose fitting supplied air respirator hood

An improved plenum type air distribution system adapted to be mounted in a head protective helmet or hood for distributing respiratation air to the interior of the helmet or hood is described which includes a combination air diffusion and noise attenuation means comprising a porous bladder or air sack connected to an air supply tube. Various materials suitable for use in making the air diffusing and noise attenuating air sack are disclosed and a preferred embodiment of the air sack is described.

Plenum type air distribution system for head enclosure

A system for monitoring the contents of a plurality of different inventories at different locations, such as for monitoring the contents of a plurality of first aid kits, some of which have different contents from others. The system includes a plurality of pairs of charts each having first and second regions thereon. The first regions contain printed matter common to all inventories or kits. Each pair of charts is associated with a single inventory or kit and the second regions thereon contain special printed matter i.e. printed matter pertinent only to the kit or inventory with which such charts are associated, normally consisting primarily of a predetermined list of such inventory or kit.
