Abstract: This invention relates to protective apparel for the human body, and in one embodiment comprises an x-ray protective apron having a main body portion and securing flaps to be wrapped around the body to secure the apron in place. The securing flaps are located approximately in the region of the small of the back when in the securing position and are characterized by being variable as to degree of tightness and by being oriented with their outermost ends in a downward direction when in the secured position, thereby effecting fastening of the apron to the body and varying weight distribution of the apron as between the wearer's shoulders and lower back.

Abstract: The present invention relates to a method and apparatus for operating an evaporative condenser refrigeration system at a low condensing temperature. The refrigeration system includes a condenser, an evaporator, a compressor, and a coolant flowing therethrough. The condenser is sized for sufficient capacity for operation at the annual average wet bulb temperature of the locality of the refrigeration system. The evaporative condenser is operated at full capacity at all times during operation of the refrigeration system. The temperature of the incoming coolant fluid to the condenser is permitted to follow the prevailing wet bulb temperature of the locality. By operating at a low condensing temperature, a compressor arranged in the refrigeration system operates at the lowest practical horsepower requirement.

Abstract: Embodiments of this invention, particularly useful as X-ray protective gloves, include an outer X-ray proof glove, and an associated inner glove, wherein the latter has an outer surface of polyester foam and an inner surface of knitted polyester, and the inner surface of the outer glove and the outer surface of the inner glove have correspondingly positioned elements of a velcro fastener in the wrist region, whereby the inner glove may be rendered removable with minimal tendency to slip with respect to the outer glove while in use.
