A package for maintaining a modified atmosphere around contents being contained therein when stored in an ambient environment is set forth. The modified-atmosphere package includes a tray, a membrane, and a structural member. The tray has a base and side walls extending upwardly from the base. The side walls and the base define a cavity wherein the contents are disposed. A membrane is attached to a top portion of the side walls and encloses the cavity. The structural member is detachably connect...

A controlled atmosphere incubator having an interior chamber surrounded by a heated water jacket. A glass access door of the chamber is directly heated by a clear, electrically conductive coating. The door is sealed against the perimeter of the opening by a readily replaceable gasket and is field reversible due to unique hinge mounting assemblies. An easily accessed blower assembly is located within the chamber and includes a HEPA filter readily replaceable by the user from within the chamber. A...

A device for sensing the oxygen content in exhaust gases in a regenerative furnace for evaluating combustion efficiency includes an oxygen probe and conduit cast in a ceramic block. Water moved through the conduit provides structural stability to the ceramic block and protects the probe against thermal damage.

As oxygen is an electron absorber it is desirable, when monitoring an atmospheric flow for the presence of tracer materials capable of detection in an electron capture detector, to remove the oxygen from the flow to the detector. The invention introduces a hydrogen supply directly into the atmospheric flow to allow the hydrogen to combine catalytically with the oxygen content of the flow to form water or water vapor. The thus formed water or water vapor is extracted from the flow proceeding to t...

A fine ozone corrosion resistant fuse wire is supported between conductive terminals which are, in turn, supported on and spaced apart by rigid insulator spacing means so that the fuse wire is extended. Insulator shield means is placed over the fuse wire over a substantial length of the insulator spacing means to shield the insulator spacing means from vaporized filament material to ensure that in all possible fuse failure modes that the circuit is completely broken but including a portion is un...

Oxidation in a leuco indigo dyebath is decreased by enclosing the air-liquor interface whereby enclosed air is depleted of oxygen by the dyebath components.

Controlled atmosphere cabinet has enclosure (110;210) with means providing visibility (110F; 210F) of its interior from outside, gas supply (113-116, 212-216) for desired or target composition of internal atmosphere, controlled lock-type access (112) for manual introduction and removal of items, and hand/arm access port provision (111A, B; 211A, B) for manipulation of said samples in the cabinet. Gas supply associated control means (230-240) serves during use of the cabinet (other than normal at...

A modified atmosphere package for storing oxygen sensitive goods containing a a gas impermeable tray including flanges around the perimeter of the tray and a bottom inside surface, and a a gas impermeable film with a bottom inside surface. The film is fitted with a one-way valve and is positioned over and adjacent to the flanges of said tray, and the film is sealed to such flanges. A support extends from the bottom inside surface of the tray to the bottom inside surface of the gas impermeable fi...

A gas generating package includes tablets or other material, which when contacted with water generates both hydrogen and carbon dioxide. A catalyst for the hydrogen-oxygen reaction is applied to the exterior of the package, with the exterior of the package preferably also having applied thereto carbon dioxide and anaerobic indicators. In this manner fresh material is employed during each run requiring an anaerobic atmosphere.

An improvement in furniture, such as a church pew, for a reverent atmosphere characterized by resilient padding on both front and back of the back rest and a fabric cover over the resilient padding. Preferably, individual speakers are included in the respective pews and covered with fabric for low overall noise level but improved ease of hearing and reverence. In church pews, it is preferred that the back rests of the pews also have a fabric covered book rack for reduced noise. Also disclosed ar...
