Abstract: A device having two elongated members pivotally connected at one end portions thereof and locked together at the other end portions thereof so that at least portions of at least two relatively rigid articles are enclosed therein and apparatus and method for moving the device from an opened position to a closed position forming an enclosure to contain the portions of the at least two relatively rigid articles. In a preferred embodiment, the two relatively rigid articles comprise radiant heating tubing and a wire mesh supported on a bed of particulate material.

Abstract: An aerial ropeway wherein oppositely located first and second sheave trains are supported on a crossarm wherein first and second sheave train supporting apparatus are pivotally mounted at fixed spaced apart locations on the crossarm and the first and second sheave train supporting apparatus are each pivotally connected to an elongated member extending therebetween.

Abstract: A carton blank having an outer layer of a relatively rigid material, a first inner layer of a relatively rigid material superposed over a portion of the outer layer and a second inner layer of a relatively flexible layer of a fluid impervious material is provided with first and second weakened portions so that, after a carton has been formed from the carton blank, filled with a desired material and sealed, the first weakened portion may be broken to form a flip top lid which when moved in an arcuate path will gradually sever the second weakened portion to form an opening in the carton so that an amount of the desired material may be removed from the carton.

Abstract: Apparatus having laminating rolls for laminating continuous strips of different kinds of material together wherein all of the continuous strips enter the nip between the laminating rolls from one side of a plane tangent to each of the laminating rolls at the nip. Also, apparatus having rotary cutting and creasing rolls located before the laminating rolls form most of the cut lines for the carton blank without changing the continuity of a continuous strip of a relatively rigid material so that it can be pulled through the laminating rolls. In those instances wherein two carton blanks are formed at the same time, scrap removal apparatus is provided for removing scrap located between the two carton blanks.
