Abstract: A continuous tubular piece is made in a continuous knit fashion. A limited area, located an equal distance from the two ends of the piece, is knit with a tighter stitch to provide a gathered area. Two similar tighter stitched, gathered areas are provided between the central gathered area and each of the ends of the piece. These two additional gathered areas on both sides of the central area are relatively spaced closer together than their spacing from the central area and the ends of the tubular piece. The tubular piece is folded back on itself using the central gathered area as a fold line, the two opposite ends being brought together. The two additional gathered areas, which were on opposite sides of the central area, are now together, one overlapping the other. A second fold is now made in the piece. The piece is folded back on itself a second time using a point midway between the two additional gathered areas as the fold line. This second fold line is a closed, smooth surface.

Abstract: A light shield for use with video display units, such as video monitors, television monitors, oscilloscopes or the like to block out ambient light. The light shield is made of a sleeve or hood having one end adapted to fit over video display units and a second end fitting over the face such that the user can view the display unit through the sleeve and limit the outside ambient light reaching the display unit.

Abstract: An emergency breathing apparatus which comprises a tubular frame and which carries a hood capable of extending over the head of an individual using the apparatus. The frame contains a pair of frame sections constructed of tubular members having internal chambers containing oxygen under pressure. The frame sections are normally shifted to a closed position and when opened, a switch on the frame permits the passage of oxygen into a plenum area surrounded by the hood. Moreover, the hood is capable of being attached to the individual in such fashion that an essentially air-tight plenum chamber is created around the face portion of the user of the apparatus. The apparatus also serves as a crash helmet inasmuch as the crown of the hood is reinforced. Moreover, the hood is provided with a two-way communication system which is automatically energized upon donning of the apparatus.

Abstract: A lightweight costume head having a hollow foundation constructed from thin slabs of foamed, elastomeric sections adhered together having an access opening and generally a cloth covering enveloping said foundation is described. The foundation generally has eye openings and may have a nose-mouth opening. The foundation comprises at least five sections cut from the flat slab of a foamed elastomer to form a head shape, frequently a spherical shape from identical sections adhered along their edges.

Abstract: The garment includes a collar portion to be worn around the neck and an auxiliary porous shield portion which is adapted to be raised in front of the face and secured along its edge to the lower edge of the visor portion of a helmet of the type worn by motorcycle riders.

Abstract: A protective garment for use with a body exhaust helmet has a hood adapted to cover the head of a wearer and the hood is provided with a fenestration in the vicinity of the eyes of the wearer. A transparent plastic sheet is secured around the periphery of the inside of the fenestration and tabs extend beyond the area of securement on opposed sides of the sheet to attach the hood to a portion of the body exhaust helmet.

Abstract: A disposable surgical hood which conforms to the wearer's head, and is usable either with a traditional surgical mask alone or with such a mask in combination with a laminar air flow face plate, contains bacterial fallout from the wearer's head and helps maintain sterile conditions in hospital operating rooms.
