Dale,

It is time consuming finding patents with just the date especially with a 
slow country connection, but I have done it and have had others help doing it 
too.  Go to patent office:

http://patft.uspto.gov/netahtml/srchnum.htm

Type in a "guess" patent number in the "query" box. For example, type in 
400000 and see what happens.  
 Next page click on "images"
This will bring up the patent and date. Patent item March 19, 1989
 Keep making up numbers until you find the number for the patent date you are 
looking for.  
Once you find a number that matches the date, then go back or forward 
adding/subtracting one number at a time until you find the patent that matches the 
item you are looking for.  In your case a sparkplug.  There might be several 
hundred patents issued for that date because from what I can observe, all patents 
issued for a particular week are given a patent date of that Monday.

There may be a simpler way, but I have not found it.

Good luck,
