The Internet is a wonderful tool for finding information but don't be fooled into thinking that if it's not on the net it hasn't been done. There has not been much work done on scanning 'pre-internet' documents onto the web. Many of the pre-internet patents still haven't been made available in electronic format.
It's also important to know how the results are ranked by the Search Engines such as Google etc..
A Google search on "Internal cooling blow moulding" will predominately list 'Fasti and 'Beco'
You will have to dig a lot deeper to find information on other methods of Internal cooling such as liquid gas (Nitrogen & CO2) - and much much deeper to discover the original invention (ISC Process) by Denes Hunkar.
