Abstract: An adjustable work holding system can quickly adjust for different sized work pieces and can grip components with a small, about 0.100 inch, grip on the material, eliminating wasted material. Adjustable jaws can be mounted on a base plate and tightened into a desired position. Grippers are attached to the jaws and extend only about 0.100 inch over the jaws to provide a gripping surface. The grippers can be resiliently held open by a resilient member, such as an O-ring. A drive bolt for each gripper can be tightened to move the grippers closer together and grip material. The grippers provide strong holding forces and pulls the work piece down, which allows for more aggressive machining operations as compared to conventional work holding systems.

Abstract: A flash tank economizer containing a first expansion device to expand high pressure refrigerant from a system condenser to an intermediate pressure and a second expansion device for further expanding liquid refrigerant at the intermediate pressure that has collected in the tank to a desired low pressure for delivery to the system evaporator. Vapor phase refrigerant produced by the first expansion in the tank is injected back into the system compressor at the intermediate pressure.
