Warm air from near the ceiling is drawn through a perforated panel and an air filter mounted in the housing. An electric fan directs the warm air downwardly through a baffle having a conical flange to form a column of warm air which is directed to the floor. A rotatable, perforated disk has wedge shaped walls to compress the air and direct the column of air to a targeted area below. A source of ultraviolet radiation is installed in the housing to sterilize the warm air.

Abstract: A flea eradicator consists essentialy of 1.7 percent by weight dioctyl sodium sulfosuccinate and 0.3 percent by weight sodium benzoate in water. The composition is topically applied and kills fleas substantially more quickly than do conventional flea soaps. The use of dioctyl sodium sulfosuccinate avoids thre problems of malodorous soaps, toxic insecticides and alkalin harshness usually associated with flea soaps. The need to incorporate polyethylene glycol or lanolin in the flea eradicator is thereby eliminated, as is the need for any other toxic insecticide. The use of sodium benzoate appears to promote healing of the infested area.

Abstract: A method of making interlocked metal tube from a strip of the metal of generally S-shaped cross-section by which the shaped strip is formed into a helix without interengaging adjacent coils of the helix, passing the helix without rotation through a rotating driving means to move the non-rotating helix axially, interengaging adjacent coils of the helix and then performing an operation to prevent subsequent disengagement of the adjacent coils, thereby to form an interlocked metal tube. The driving means for the helix is a rotatably-driven mandrel around which the open helix is placed. The mandrel has intermediate its ends a radially-outwardly extending integral portion in which there is a helical passageway forming a tunnel through which the helix is passed and from which the helix is delivered to move without rotation axially along the remainder of the mandrel.

Abstract: An EDM apparatus having a first support member for the workpiece and a second support member for the guide members of an electrode wire. A cross-slide provides relative linear motions between the two support members for effecting a cut in the workpiece by the electrode wire. A third support member carrying a form electrode tool is arranged to be selectively held stationary either relative to the first support member, by an appropriate first coupling member, or relative to the second support member, by a second coupling member. Under the first condition, the cross-slide provides the necessary relative linear displacements between the electrode wire and the form electrode tool for cutting the electrode tool by the electrode wire and, under the second condition, the same cross-slide provides the necessary displacements for sinking the electrode tool into the workpiece.

Abstract: A support for use in conjunction with a camper (carriable by a conveying vehicle) and a plurality of conventional lifting jacks is constructed from square cross section ferrous tubing. The support is collapsible from an assembled state in which it supportively abuts the bottom of the camper when the camper is not carried by the vehicle. The support eases at least a significant portion of the load of the camper from the jacks, so as to avoid buckling of the camper sides by the jacks. Preferably, the jacks are maintained in position to stabilize the camper against transverse movement caused by wind or by movement inside the camper. The support is constructed from a pair of opposing end elements, each having a pair of vertical members connected by a horizontal cross member, and an upwardly opening socket on the upper ends of the vertical members.
