Abstract: ABSTRACT OF THE DISCLOSURE The present invention relates to a fan unit which may be used either as a floor fan or as a window mounted fan.          When used as a floor fan, the frame is supported on the floor and the motor driven fan unit, which is pivotally connected to the frame, may be rotated to provide air flow in any direction.  The fan unit comprises rises an open frame having a motor driven fan connected to the rear portion thereof, a pair of protruding pins on the frame front portion which engage the window on the outside thereof, and a second pair of protruding pins on the frame front portion which engage the window frame on the inside thereof.  The motor driven fan is suspended in this manner inwardly away from the window opening such that the cantilever effect produced thereby pulls the first pins inwardly against the window and pushes the second pins outwardly against the window frame.  The frame of the fan diverges slightly in the vertical direction so that it is, in effect, wedged into the window opening and makes it more diffi-cult to remove accidentally and strengthens the frame.  The unit is easily adapted for use with a horizontally sliding window by attaching a pair of removable laterally extending brackets.

Abstract: ABSTRACT OF THE DISCLOSURE         A process for catalyzing the sulfurization of olefins and the resulting products are disclosed in which the catalyst is a tertiary phosphine such as a trihydrocarbyl phosphine or a trihydrocarbyl phosphine sulfide. to catalyst is preferably soluble in the olefin and, in the presence of elemental sulfur, the reaction mixture is heated to a temperature sufficient to sulfurize the olefin.  The catalyst enables the sulfurization to proceed at lower temperatures than would be employed without catalysis.  Atmospheric pressure production is possible of high sulfur-containing olefins which normally boil or reflux strongly at or below sulfurization temperatures.  In addition, the product of the catalyzed reaction has certain advantages, such as improved oil solubility with no subsequent dropout.

Abstract: ABSTRACT         In a dual component packing of the type comprising a flexible bag, which contains single liquid components in respective separate compartments, from which they may be brought together into a common mixing compartment by exterior manipulation, a mixing stick is mounted inside the packing so as to be grippable at one end by squeezing together the bag sheet material thereabout, whereafter the free end of the mixing stick by exterior manipulation can be moved around in the mixing compartment for effectively stirring and mixing the combined liquid components.  Exterior pressure manipulations on the bag itself will be superfluous, and for this reason a packing of a simple flat bag type may be bottomwise designed so as to assume a cup shaped form when placed on a substantially planar support surface, whereby an effective mixing stirring by means of the said mixing stick is achievable.

Abstract: 78.41 Abstract of the Disclosure For skelp to make pipe having a seam butt-joined as by electrical resistance or submerged arc welding, skelp is made by pouring a base melt of rimming steel into an ingot mold to about 80 to 95% full and then after a shell of rimmed steel has solidified against the mold wall, com-pleting pouring of the same melt while adding further material to the molten core, e.g. more C or Mn, and Al or the like for killing, so that the solidified ingot has a core of desired high strength, killed or semi-killed steel.  The ingot is processed to desired skelp by hot rolling, the top and bottom regions being suitably cropped, so that the skelp has a main body of the high strength steel, bordered lengthwise by integral edge zones, e.g. 1/2 inch or more wide, of the rimmed steel, free of unwanted inclu-sions.  When rolled to pipe shape, with finished edges, the edge zones are electrically butt welded, such operation being effected with unusual facility.  In the completed pipe, the weld region is relatively free of oxide or like inclusions, and thus not susceptible of rejection for defects at or about the seam, while the pipe is essentially characterized by high wall strength.
