Abstract
Abstract A container divided into a plurality of cells for the storage and shipment of animals, birds or live specimens for biological study in which each animal, bird or specimen is isolated in a separate cell and each cell has a controlled atmosphere by supplying it with clean, filtered air that is thermostatically controlled to a predetermined temperature and predetermined humidity. The airflow may also be treated with a germicidal lamp to kill and eliminate any disease germs. Each container may have an electric plug in for AC power supply and an auxiliary DC power supply to maintain all components active whenever the AC supply is removed or fails. Additional features may be provided such as a water supply for drinking and screen floors and floor trays for drainage.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
195 words
A mobile container for the storage and shipment of animals, birds and live specimens individually for biological study which includes an enclosing casing, a plurality of casters to support said casing, a battery of removable isolated and sealed cells mounted with said casing, a motor-driven recirculation air source to supply a flow of air through a separate continuously open inlet to each cell and a separate exhaust outlet from each cell, an air-conditioning unit that includes a filter and germ removing means in said air source, said inlet to each cell individually receiving clean air from said filter and germ removing means, said outlet from each cell directing used and foul air from said cell back through separate return ducts to said recirculating air source, a heater in each cell, said heaters controlled by a thermostat in each cell, a transducer within each cell to indicate the humidity, a variable rheostat connected to said heaters to regulate the amount of heat supplied to each cell, the above arrangement constituting a house means to each animal, bird or live specimen separately in an independent cell and maintain a desired atmosphere within each cell of said container.
Claim 2
Dependent Claim
195 words
A mobile container for the storage and shipment of animals, birds and live specimens individually for biological study which includes an enclosing casing, a plurality of casters to support said casing, a battery of removable isolated and sealed cells mounted with said casing, a motor-driven recirculation air source to supply a flow of air through a separate continuously open inlet to each cell and a separate exhaust outlet from each cell, an air-conditioning unit that includes a filter and germ removing means in said air source, said inlet to each cell individually receiving clean air from said filter and germ removing means, said outlet from each cell directing used and foul air from said cell back through separate return ducts to said recirculating air source, a heater in each cell, said heaters controlled by a thermostat in each cell, a transducer within each cell to indicate the humidity, a variable rheostat connected to said heaters to regulate the amount of heat supplied to each cell, the above arrangement constituting a house means to each animal, bird or live specimen separately in an independent cell and maintain a desired atmosphere within each cell of said container.
Claim 3
Dependent Claim
34 words
In a device according to claim 1 in which said heaters, said thermostats and said transducers in each cell are individually controlled to provide a desired atmosphere that may be predetermined for each cell.
Claim 4
Dependent Claim
51 words
In a device according to claim 1 in which a DC storage battery is also enclosed in said casing and connected to said AC circuit as a standby unit, means to maintain said circuit energized with either AC or DC and means to operate said blower with either AC or DC.
Claim 5
Dependent Claim
42 words
In a device according to claim 1 in which a water tank is also enclosed in said casing and connected to each cell to provide a supply of drinking water, means to regulate the flow of water as predetermined for each cell.
Claim 6
Dependent Claim
31 words
In a device according to claim 1 in which said germ-removing means is a germicidal lamp and a filter located in said air duct to kill and eliminate any disease germs.
Claim 7
Dependent Claim
74 words
In a device according to claim 1 in which each cell is provided with a wire mesh floor above the cell bottom and a slideable tray on said cell bottom, a trap door opposite the side of each tray for removing said trays for cleaning, said trap doors biased closed, means to maintain air pressure greater than atmospheric pressure within each cell when opening said trap doors for removing and cleaning said floor trays.
Claim 8
Dependent Claim
22 words
In a device according to claim 1 in which each cell is provided with a lamp, means to illuminate any cell individually.
