It is an improvement in radiator construction. I am just over from New Zealand & have had accompanying sample made here. It is on the same principal as the old way of freezing meat by compressing & cooling of air. If you blow through the front of sample you will find the air passing through to be cool but if the sample is turned round & blown through the back, you can hardly feel the air. Will you please test sample & see what you think of it. I have taken out a provisional patent in this country & will if you wish come to Derby to see you but as I am only a mechanic I do not have much cash to spare & therefore hope you will be able to do something with the idea. The thing can be modified either by making the V's deeper or more shallow & the slots coarser or more fine. If you | ||
