Abstract: Return air from a work area is so treated as to arrive at a prescribed temperature/humidity level responsive to a direct acting absolute humidity sensing and control apparatus. The return air is mixed with fresh air, then subjected to a water spray in an air washer. The air mixture is controlled by the absolute humidity control device to maintain a constant absolute humidity level. The amount of water sprayed is controlled by a dry bulb thermostat which in turn operates to throttle the spray as necessary to reach the prescribed temperature level in an evaporative cooling technique.

Abstract: A packaging container for protection of fragile articles during shipping and storage, and a method of packaging thereof, utilizes a space minimizing outer carton and a plurality of innerpacking support panels selectively attached to the contained article by means of a heat shrinkable overwrap or film. Two types of support panels are selectively employed including a first plurality of cushioning pads having a spaced top, bottom, and side wall structure which creates an air space therebetween, and a second plurality of separator panels for insertion adjacent non-fragile or separable components of the contained article.The effective horizontal dimensions of the support panels exceed the largest horizontal diameter of the article being packaged, and is further substantially equal to the effective inner dimensions of the outer carton. Thus the wrapped article and the component thereof are held against movement within the carton; the carton itself is reinforced.

Abstract: A safety screwdriver having a handle and a shank portion which includes an axially extending tubular extension surrounding a substantially rectangular blade recessed within. In the preferred embodiment the blade and tubular extension are a unitary construction with opposite side edges of the blade integrally cast to the side walls of the tube.

Abstract: The exposed welt of a footlet-type sock is divided by knit construction into a rear portion and a front portion. The rear portion, which is substantially the rear half, is of a substantially freely and outwardly rolled construction. The rolled rear portion is not tacked down and encircles the lower ankle area when emplaced on the foot. The remainder or front portion includes an upper edge which is tacked down in a controlled folded construction. The rear portion is thus left free to roll upon itself into a relatively heavy, thick mass of material. The front portion, on the other hand is folded across the instep of the wearer minimizing the thickness of material beneath the shoe tongue. The rear half is a knitted fabric formed with a combination of body yarn and elastic yarn. The elastic yarn forms the backing fabric for the body yarn, which itself is formed into terry loops.

Abstract: A pair of opposed arms extend in spaced parallel arrangement to each other, each of which arms include relatively short handle portions and relatively long gripping portions. The inner or opposed gripping edge of each arm includes a plurality of jagged teeth formed by relatively deep notches in the opposed edges of the arms. The teeth and notches are provided throughout substantially the entire gripping portion. The notches extend into the surface of the arms a distance of at least one-half inch. The arms are joined together by a connection about a pivot point positioned intermediate the handle portion and the gripping portion. A compression spring extends between the handle portions for normally biasing the gripping portions toward a closed position. One of the handles of the device receives one end of a tether which is attached at the other end to the boat.

Abstract: Coal is ground or pulverized to an extremely small particle size (6 microns or less) and introduced into a mixing chamber where the coal powder is atomized or mixed with air to form a cloud of coal particles entrained in air. Prescribed, controlled amounts of the coal powder/air mixture are withdrawn from the mixing chamber and fed to the burner nozzle of a furnace, from which nozzle the mixture is directed to a combustion zone. The igniter for the system is positioned at the combustion zone and is preferably a strong electric arc, although other igniters could be used. After combustion exhaust gases from the furnace are withdrawn and cleaned up through a water filter in which a plurality of screens are kept flushed with water passing in one direction as the combustion gases pass in the opposite direction to the atmosphere.

Abstract: A fluid operated reciprocal slide picks off fasteners, one at a time, from a delivery slide and delivers the fasteners to a flexible conduit. The same fluid that moves the aforementioned slide drives the fastener into the flexible conduit and on to an automatic fastener insert mechanism. The fluid drive is selectively activated by the trigger at the automatic fastener insert mechanism.

Abstract: A combination comfort pad, restraining harness, and coverlet is so constructed as to be attachable to an existing infant seat. The pad section has a moisture-proof innerlining which overlies the back and seat portions of the infant seat. The harness is spaced above the surface of the pad section and has a base portion and a pair of midriff straps separated from the base portion by notched areas. The midriff straps are of an adjustable length sufficient to wrap around the infant and the infant seat to fasten together thereunder. At least one and preferably two coverlets, of varying weights, are attached to the lower end of the pad. When one or both of the coverlets are not in use they are tucked away to the underside of the infant seat.
