Disclosed is a portable apparatus which adsorbs trace toxic fumes for a wide diversity of situations. The apparatus consists of a gas-tight enclosure, attached flexible duct and floating support arm, adsorbent filter, exhauster blower and quick disconnect fasteners. The blower sucks the toxic fumes through the filter and discharges the treated air back into the laboratory. The flexible duct/floating arm captures the toxic fumes in a wide range of conditions and the quick disconnect fasteners permit the rapid replacement of spent filters. It is the quick-disconnect fasteners between the cover of the box and between the filter and the cover which permit rapid replacement of the spent filters. This flexible apparatus minimizes interference with visual and hand operations, conserves room energy, removes particulate by both the change in direction designed in the apparatus and the non-woven fabrics used to support the adsorbent particle bed. One embodiment of the portable apparatus includes a table box having a foraminous surface onto which a specimen which emits fumes is placed, with the table box being in communication with the gas-tight enclosure so that fumes which are heavier-than-air are sucked into the table box and then into the gas-tight enclosure, while the placement of the flexible duct above the specimen conducts fumes which are lighter-than-air directly into the gas-tight enclosure.

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.

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.

Apparatus for treating a shoreline against contamination from an oil spill on adjacent waters comprising a first vehicle for laying down a web of oil absorbing material on said shoreline and taking up said web after it has absorbed oil, a second vehicle for transporting said first vehicle and said webs to the area of said shoreline, and a third vehicle for storing oil extracted from said web by extraction mechanism on said first vehicle. An all-terrain vehicle for laying a web of oil absorbing material on a shoreline including a vehicle body supported by a plurality of wheels, means on said body for supporting a coiled web of said oil absorbing material and for guiding said web onto said shoreline, and means for coiling said web back onto the vehicle and extracting oil therefrom. A method of treating a shoreline against contamination from an oil spill comprising the steps of transporting a web laying vehicle and a plurality of oil absorbing webs to said shoreline, causing said web laying vehicle to lay said oil absorbing webs onto said shoreline, taking up said oil absorbing webs and extracting oil from them, and conveying said extracted oil away from said shoreline. A web for use in absorbing oil deposited on a shoreline including spaced layers of plastic netting confining shredded polyolefin fibers therebetween.
