A toxic substance extraction cell includes a chamber for housing a heated solvent, a pair of gaskets adapted to be seated on the solvent housing between which is clamped a specimen to be tested; the space between the gaskets being liquid tight, and a cover for clamping the gaskets to the solvent housing. After assembly of the cell with the preheated solvent in the housing and the specimen to be tested between the gaskets, the cell is inverted and supported on a plurality of legs provided on the cover. The solvent is thus placed in contact with the specimen in order to dissolve any toxic substances contained within the specimen. The cell is then reinverted and supported on a suitable stand and allowed to cool, disassembled, and the solvent removed and tested for toxic residue.

Extraction cell

Apparatus for automatically applying tape to effect the closing of a carton, such tape to be placed not only across the top surface but also continuously down each end of the carton. The apparatus includes means for advancing the containers with the top flaps in folded position into an initial station where the leading end has applied to it one end of a length of tape and where the end flaps and tape are pressed into position by downwardly extending rollers. The rollers are then retracted and the carton is moved under a tape supply which tapes the top of the carton and moves the carton into a second station at which point a mechanism cuts the trailing edge of the tape to size and the carton is moved upwardly into a stacking chute having side rails which engage the taped ends of the carton insuring that they are folded into position and holding them in position while the adhesive has time to set.

Taping apparatus

Apparatus for closing and gluing containers which are of the type assembled from two pieces including a slotted tray with an outer sleeve which telescopes over the assembled tray and which has top flaps foldable into position as the top of the container. The tray is assembled and the sleeve is placed thereon prior to filling and the filled container is then directed into the apparatus which raises the outer sleeve to allow adhesive to be applied to the tray and at the same time allow the flaps to be glued and folded into position, the outer sleeve subsequently being pressed into position and held in that configuration until the adhesive can set, the finished container having adhesive holding the sleeve to the tray and the outer closure flaps sealed.
