Upon failure of the cord or spring of the standard window system the safety member suddently pivots outwardly under spring pressure to engage the inner wall of the window frame.

Abstract: Mounting of the circularly fitted inserted tooth of a circular saw. An inserted tooth (4) having a circular mounting surface is mounted on a blade body (1) and into a round-bottomed notch whose opposite edges are parallel. Tooth (4) is locked in the notch by means of a rivet (6) which is positioned in a juncture between the removable tooth and the blade body along a straight portion of the edge of a notch. Such locking facilitates a strong design for said tooth and even a loose tooth can be re-tightened in position by means of the flattening pressure of said rivet.

Abstract: A detachable safety frame is constructed from four individual members which are assembled into a rectangular frame detachably attached at each respective adjacent and adjoining end. The frame is assembled into either existing cable openings of installed transformer and mounting pad installations or may be incorporated into new installations during the installation of the transformer on the mounting pad. In the version used for new installation, the individual frame members are of such size as to extend downwardly into the hole in the ground which is dug for the cables. Each end of each member is provided with a projecting tab and slot for engagement and disengagement to assemble or disassemble the frame.

Abstract: Contaminated oil is reclaimed for uel use by pumping same through an oil filter into one side of a divided tank then through a heater to burn off water and antifreeze and then into the other side of the divided tank where the oil is blended with other clean oil, such as diesel fuel, which is then pumped through a water separator and another oil filter into a fuel supply tank from which it is pumped and used for blending. The divided tank is mounted on wheels and carries the various components such as pumps, heater, valves, piping, filter and so forth.

Abstract: An elongated, cylindrical metal sleeve has a soft cylindrical, elastomer cover. A shaft is mounted through the core in a bearing slip-fitted in each end and held in place by a snap ring on one end snapped into the metal sleeve and on the other end by a circular collar having a protruding tooth or dog, which is press-fitted into the metal sleeve and slides into the keyway in the shaft. A collar is fitted on each end of the shaft to limit the amount of oscillation of the roller. The ends of the shaft are mounted on a printing press in a bearing cup or some other way.
