Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
109 words
A system for testing an engine comprising, in combination: test means for testing said engine; pallet means for supporting said engine; and a dial index adapted to receive said pallet means at a loading station and adapted to discharge said pallet means at an unloading station, said dial index advancing said engine from said loading station to said test means and then to said unloading station at a predetermined index rate, said predetermined index rate being defined by a series of indexes by said dial index and a series of predetermined stationary periods between each of said indexes, whereby said engine is normalized upon arrival at said test means.
Claim 2
Independent Claim
109 words
A system for testing an engine comprising, in combination: test means for testing said engine; pallet means for supporting said engine; and a dial index adapted to receive said pallet means at a loading station and adapted to discharge said pallet means at an unloading station, said dial index advancing said engine from said loading station to said test means and then to said unloading station at a predetermined index rate, said predetermined index rate being defined by a series of indexes by said dial index and a series of predetermined stationary periods between each of said indexes, whereby said engine is normalized upon arrival at said test means.
Claim 3
Dependent Claim
24 words
A system as claimed in claim 1 wherein said pallet means and said dial index cooperatively define operating means for operatively activating said engine.
Claim 4
Dependent Claim
20 words
A system as claimed in claim 2 wherein said operating means supplies water, electrical power and fuel to said engine.
Claim 5
Dependent Claim
16 words
A system as claimed in claim 1 or 2 wherein said predetermined index rate is variable.
Claim 6
Dependent Claim
24 words
A system as claimed in claim 1 wherein said dial index is rotatable about a base, said base defining a pair of water troughs.
Claim 7
Dependent Claim
37 words
A system as claimed in claim 1 or 5 wherein said dial index defines a series of pallet-receiving stations, each of said pallet-receiving stations including a pallet stop plate adapted to matingly engage with said pallet means.
Claim 8
Dependent Claim
20 words
A system as claimed in claim 6 wherein said pallet support plate is interconnected to said pair of water troughs.
Claim 9
Dependent Claim
47 words
A system as claimed in claim 6 further comprising a D.C. power supply, said dial index including interconnect means for connecting each of said pallet stop plates to said D.C. power supply and for maintaining the connection therebetween during advancement of said engine by said dial index.
Claim 10
Dependent Claim
20 words
A system as claimed in claim 5 further comprising means for cooling the water within said pair of water troughs.
Claim 11
Dependent Claim
31 words
A system as claimed in claim 1 or 2 wherein said dial index further includes starter means for engaging and starting said engine as said dial index receives said pallet means.
Claim 12
Independent Claim
26 words
A system as claimed in claims 1 or 2 further comprising a sequence control, said sequence control operating and monitoring said engine during normalization and testing.
Claim 13
Independent Claim
109 words
A system for testing an engine comprising, in combination: test means for testing said engine; pallet means for supporting said engine; and a dial index adapted to receive said pallet means at a loading station and adapted to discharge said pallet means at an unloading station, said dial index advancing said engine from said loading station to said test means and then to said unloading station at a predetermined index rate, whereby said engine is normalized upon arrival at said test means; said dial index defining a series of pallet-receiving stations, each of said pallet-receiving stations including a pallet stop plate adapted to matingly engage with said pallet means.
Claim 14
Independent Claim
109 words
A system for testing an engine comprising, in combination: test means for testing said engine; pallet means for supporting said engine; and a dial index adapted to receive said pallet means at a loading station and adapted to discharge said pallet means at an unloading station, said dial index advancing said engine from said loading station to said test means and then to said unloading station at a predetermined index rate, whereby said engine is normalized upon arrival at said test means; said dial index defining a series of pallet-receiving stations, each of said pallet-receiving stations including a pallet stop plate adapted to matingly engage with said pallet means.
Claim 15
Dependent Claim
35 words
A system as claimed in claim 12 wherein said predetermined index rate is defined by a series of indexes by said dial index and a series of predetermined stationary periods between each of said indexes.
Claim 16
Dependent Claim
24 words
A system as claimed in claim 13 wherein said pallet means and said dial index cooperatively define operating means for operatively activating said engine.
