OLD INSTRUMENTS PAGE
|I WOULD LIKE TO DEDICATE THIS PAGE TO THE OLD INSTRUMENTS USED IN THE YESTER YEARS OF OCTANE AND CETANE DETERMINATION. MAINLY KNOCK AMPLIFIERS, BOUNCING PINS & CETANE METERS. MANY OF WHICH ARE STILL HANGING AROUND OUR LAB. ( I DON'T THROW ANYTHING AWAY ANYMORE ). BUT ANYTHING COULD HAPPEN, LIKE A MAJOR HOUSE CLEANING AND THEY WOULD BE GONE FOREVER. I WOULD LIKE TO GIVE THESE ITEMS TO SOMEONE, PERHAPS A MUSEUM. SOME OF THESE ITEMS I HAVE NEVER SEEN ANYWHERE ELSE. IT WOULD BE MOST UNFORTUNATE IF THESE THINGS WERE LOST FOREVER.|
Old Bouncing Pin Amp. Dated 1945. In a nice metal box with carrying handle. Complete with latchable door. This is a vacuum tube model. I guess it was some what portable, it weighs about 20 lbs.
|This is the famed Bouncing Pin.
I understand this was the source of a lot of cursing. I imagine the adjustments on this device were very time consuming to get just right. These knock sensors were last used about 1952, then Phillips introduced the D-1 Pickup.
|Close up of the Bouncing Pin. For some reason, I still have a whole drawer of B.P. parts. Don't ask me why.|
|This is a better picture of the engine I restored, and now used for open house displays. The kids love to crank on that handle!|
|This is an early Cetane Engine using two Bouncing Pins. It has 38 written on the picture, I'm guessing that's 1938.|
|This is it so far. I will be adding more shortly. Email me if you have some old pictures of octane equipment being used. Or have other content that would be interesting to the knock folks.|
