The National Fluid Power Association (NFPA) published a new ISO
standard --ISO 5781:2000--that addresses the interchangeability of valves in
hydraulic systems. Valves covered in the new standard include pressure-reducing
valves, sequence valves, unloading valves, throttle valves, and check valves.
The standard applies to valves used in industrial equipment such
as machine tools and packaging equipment. It specifies dimensions and other
characteristics of the surfaces on which the valves are mounted.
NFPA is making the documents available for $43 for NFPA members.

Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
