Abstract: A pilfer-resistant peg hook assembly for supporting a plurality of articles incorporating defined slots and enabling only one article at a time to be removed therefrom is formed of a peg hook and a flipper. The peg hook has a pair of opposed ends and a body connecting the same. One of the hook ends is configured and dimensioned to maintain the hook body in a substantially horizontal first plane when mounted on an appropriate surface, and the other of the hook ends is a free end. The hook body is configured and dimensioned to be received in the slots of the articles and extends only in the first plane. The flipper is pivotably secured adjacent the free end and is movable between an enabling orientation enabling at least partial passage of an article along the hook body and onto the flipper as the article initially moves towards the free end, and a blocking orientation precluding passage of an article onto the flipper as the article moves towards the free end.

One of the hook ends is configured and dimensioned to maintain the hook body substantially horizontal when mounted on an appropriate surface, and the other of the hook ends is a free end. The hook body is configured and dimensioned to be received in the slots of the articles and defines a vertically extending bump adjacent to but spaced from the free end. The flipper is pivotably secured adjacent the free end and is movable between an enabling orientation enabling at least partial passage of an article along the book body and onto the flipper as the article moves towards the free end, and a blocking orientation precluding passage of an article onto the flipper as the article moves towards the free end.

Abstract: Apparatus for precisely regulating the paraffin temperature in an electrically heated tissue processor comprises a sensor which is detachably fastened to the tissue processor by a clamp so as to be partially immersed in the paraffin. A controller, coupled to the sensor, and coupled in series with the tissue processor heating element by a plug tap across a source of alternating current voltage, is responsive to the conduction state of the sensor and controls the delivery of power to the tissue processor heating element in accordance with the paraffin temperature as sensed by the sensor.

Abstract: Disclosed is an apparatus which attaches to an automatic tissue processor to confine and treat the toxic fumes emanating from solvent containers used in a tissue processor. The apparatus consists of a framework clamped on the tissue processor upon which an adsorbent filter and exhauster/blower assembly are mounted and a transparent flexible cover are placed. The blower sucks the toxic fumes and intake air through the adsorbent filter where the fumes are removed from the air. The clear flexible cover has zippered panels with attached fasteners to observe tissue processor operation and provide the technologist access to the tissue processor for operation and maintenance.
