Abstract: Abstract A method and apparatus is disclosed for feeding welding flux to both the leading and trailing sides of the strip electrode used in a submerged arc strip cladding process.  In order to prevent distortion of the bead shape the pressure due to the weight of the flux burden is controlled to be less in the region of the molten metal and slag pools lying directly behind the welding arc.  The flux burden is caused to increase from a first depth directly behind the strip to a maximum depth at the trailing edge of the weld crater region where the quantity of liquid metal and liquid slag is a minimum.

Abstract: ABSTRACT OF THE DISCLOSURE   A stabilizer assembly is provided herein.  The assembly includes, in combination, a torsion bar having a central portion and end, ???? the  end portions being twistably mounted on the frame of a vehicle, ??? slidable braking device disposed at at least one end of the torsion bar   The slidable braking device has a slidable cylinder member and a fixed piston mem-ber secured, respectively, to the end portion of the torsion bar and the mov-ing portion of the swing arm of the suspension system of the vehicle.  The slidable cylinder member and fixed piston member are reciprocal relative to each other under a certain braking force with the stroke thereof being limited to a length smaller than the maximum twistable amplitude of the ends of the torsion bar.  The end portion of the torsion bar has such inertias as to induce the sliding action of the slidable braking device.  This stabili-zer thus includes slidable braking device for controlling a torsion bar so that it rarely or only slightly acts when the vehicle runs in a straight path, but which effectively acts when the vehicle turns.  Thus, the initial distor-tion of the torsion bar  has no effect upon the stabilizing action unless the resultant spring-back force exceeds the predetermined frictional resistance. The stroke of the slidable braking device is limited to about 15 mm from a neutral position  This limited stroke overcomes the unevenness in the road surface, and produces a roll angle of about 1". which does not effect the vehicle very much when running under heavy turning conditions.

Abstract: Abstract of the Disclosure Stocking toe end closing apparatus of the type having a series of horizontal stocking turning tubes mounted on a rotatable base for indexing to a position for spreading stocking toe ends carried on supports, and for further indexing to a seaming position where the stocking toe ends are closed.  The turning tubes are connected to a suction source at index posi-tions before and after the spreading and closing positions for everting stockings thereat.  Spreading fingers are inserted into the open free ends of the supported stockings at the spreading position and expand through longitudinal slots in the tubes for lateral spreading of the stocking toe ends to a width suitable for seaming, and the fingers are then moved away from the support end in a diagonal direction with respect to the elongation of the tubes in synchronism with the index motion of the tube, so that the stocking toe end is carried by the fingers to a posi-tion where the fingers and the toe end extremity lie beyond an arcuate clamp which then engages the widespread toe end in posi-tion for rotation of the clamp and the toe end extremity past a sewing machine for closing.  Tubular guards with matching longi-tudinal slots are provided for exposing alignment and shielding non-alignment with the slots in the tube ends to prevent inter-ference with the everting of stockings by the tube end slots.   Exhaust air produced from the same suction source that provides suction for everting stockings is passed through a nozzle adja-cent the clamp onto the toe end extremity for directing it into the sewing machine.  The clamp rotates in reverse direction after seaming to pay out the stocking which has wrapped partly around it during seaming, in synchronism which the index motion of the stocking support away from the seaming position.  An endless belt is supported in deflected engagement with the stocking tube at the seaming index position, and during a portion of its index motion to and away from that position, as a means of restraining the stocking from sliding off the support as it is partially with-drawn for positioning the toe end at the sewing machine and by wrapping around the clamp during seaming.
