Power adapters for providing power to accessory devices in refrigerated containers are provided herein. The power adapter comprises a first connector communicatively coupled with a plurality of conductors; a second connector communicatively coupled with two or more of the plurality of conductors; and a shunt communicatively coupled with at least four of the plurality of conductors and configured to provide power to an accessory output in response to the accessory connection being communicatively coupled with an accessory device.

Apparatus for powering an accessory device in a refrigerated container

A method of removing arsenic and fluoride from aqueous solutions in the same process is provided. Specifically, the pH of the aqueous solution is adjusted to a pH in the range of about 5 to 8. A combination of calcium salts, and ferric or aluminum salts are added to form insoluble arsenic and fluoride bearing solids. The solids are then removed from the aqueous solution.

Method for simultaneous removal of arsenic and fluoride from aqueous solutions

A valve for a wafer processing machine is formed with a wedge-shaped sliding gate. A folded wafer handling arm is stored within the wedge and pumped to keep the arm clean while the valve is closed.

Valve incorporating wafer handling arm

A wafer is introduced into a processing chamber on a transport device. Lifting pins receive the wafer from the transport device and lower the wafer to the surface of a chuck. Clamping pins lower and hold the wafer by means of enlargements on the ends of the clamping pins. Grooves on the surface of the chuck and internal channels in the chuck are used to supply gas to the back of the wafer for temperature control.

Wafer processing chuck using slanted clamping pins

A wafer processing system including wafer handling arms incorporated into vacuum isolation valves is described. A loadlock with elevator and optical sensors is used to inventory and position a cassette of wafers. The wafers in the cassette can be randomly accessed. A computer is used to control the system according to a task status table independent of time sequence.
