Abstract: ABSTRACT:           The method for creating an environmental seal for the end of a severed multiconductor cable and for sealing the joints between the conductors of such cable with the contacts of a multiple contact connector into which such cable is inserted.  A tape of a soft, pliant material is coated on both sides with a flowable, pressure-sensitive adhesive and is formed into a blank which can be adhered to the cable in various ways.  In a first form, the blank encompasses the severed end and portions of the cable adjacent the end.  When the connector into which the cable has been inserted is compressed, the adhesive is displaced to seal the contact-conductor joints.  Folded-over end flaps seal the cable ends.  A midspan use of the blank permits the joints to be sealed without reference to the cable end.

Abstract: ABSTRACT OF THE DISCLOSURE A support structure for a soot blower assembly of the type having a carriage, a lance and a feed tube. The support structure comprises a lance tube support arm and a feed tube support arm, each of which is in engagement with connecting means. The connecting means maintains a pivotal relationship between the support arms, which alternate in assuming a supporting position and a retracted position. In operation, the soot blower carriage travels toward the supporting arm, passing over the retracted arm. The carriage engages the supporting arm, which pivots first upward and then downward toward the retracted position. As the arm travels downward, the previously retracted arm is pulled into the supporting position by virtue of the downward motion of the first arm and the means which connects them. Thus, as the carriage travels along, the support arm in front of it is retracted so as not to obstruct its path and a support arm behind it is raised. The device works similarly in either direction of travel of the carriage.

Abstract: ABSTRACT OF THE DISCLOSURE     The invention is concerned with a method of produc-ing sheet-metal lids for containers, in which the lid-blanks are stamped out of sheet- or strip-metal, are provided with a pouring area, are then formed and are provided with a pro-tective coating impeding corrosion, whereupon a flexible closure-strip is applied to the surface of the lid by gluing or hot-sealing for the purpose of sealing the pouring area hermetically.  The method of the invention is characterized in that after a hole-pattern defining the pouring area has been stamped out of the sheet, the stamping burrs produced around the holes are removed by subjecting the sheet to an electro-chemical treatment.  The invention enables one to remove the burrs in a reliable, practical and inexpensive manner and thereby prevents any corrosion at the edges of the holes, which may react with the substance in the container and render it unserviceable.
