Abstract: An applicator for applying an active agent to a living surface is provided in which a strip of film has a peripheral portion on one side thereof coated with pressure sensitive adhesive, the adhesive surrounding a central portion which carries a liquid containing an active agent. The strip is folded upon itself and held in the folded position by the pressure sensitive adhesive to confine said active agent and prevent its contamination. Also, the strip has flaps uncoated with pressure sensitive adhesive extending beyond the adhesive-coated portion to facilitate opening the folded strip without contacting the active agent.

Abstract: Apparatus is disclosed for holding an arrow in a pulled bow and which releases the arrow when the bow is pulled slightly beyond the position in which the arrow is held. This is accomplished by a support attached to the bow which carries a movable arrow-holding bar having a point-receiving indentation. This bar is movably mounted to shift from an arrow-holding position in front of the point of the arrow in the pulled bow to a second position out of the path of the arrow. Trigger members are carried by the support immediately forward of the bow to move the bar into the path of the arrow, and a spring device is provided to bias the bar out of the path of the arrow so that the arrow will be freed of the obstruction provided by the bar when the point of the arrow is pulled out of the indentation. When the bar is positioned to the rear of the bar, and when an arrow guide is positioned at the rear of the support, short arrows which do not reach the bow when the string is fully pulled can be used.

Abstract: Solar powered cooling apparatus is disclosed in which liquid refrigerant is vaporized in a collector/evaporator by solar radiations concentrated by a reflector, and the pressurized vapors operate an aspirator to reduce the pressure in an evaporator containing the same liquid refrigerant to cool the same. The mixture of vapors leaving the aspirator are condensed in a higher positioned condenser and supplied to a gathering vessel from which the liquid refrigerant is forced back into the collector/evaporator with the assist of pressurized vapors periodically withdrawn from the collector/evaporator.
