Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
122 words
An inlet grill for supplying gases with varying conditions for control of dwelling rooms, comprising a plurality of elongated blades disposed with their edges facing the supply of gas, said blades constituting guide bars for guiding the gas stream, characterized in that at least of some of the blades are automatically adjusted to different angles relative to the flow direction in response to the varying conditions of the supplied gas, said blades being made of a material which can be bent or flexed to change the angular deflection of the gas stream through the grill, and including bimetal strips secured to said blades transverse to said edges to effect bending of said blades in response to temperature changes in the gas stream.
Claim 2
Dependent Claim
122 words
An inlet grill for supplying gases with varying conditions for control of dwelling rooms, comprising a plurality of elongated blades disposed with their edges facing the supply of gas, said blades constituting guide bars for guiding the gas stream, characterized in that at least of some of the blades are automatically adjusted to different angles relative to the flow direction in response to the varying conditions of the supplied gas, said blades being made of a material which can be bent or flexed to change the angular deflection of the gas stream through the grill, and including bimetal strips secured to said blades transverse to said edges to effect bending of said blades in response to temperature changes in the gas stream.
Claim 3
Dependent Claim
33 words
A grill according to claim 1, characterized in that the automatic adjustment of the blades at least partly alters the flow area of the nozzle in connection with the change of the angle.
Claim 4
Dependent Claim
15 words
A grill according to claim 1 including fixed blades connected with said angularly adjustable blades.
Claim 5
Dependent Claim
29 words
A grill according to claim 3, characterized in that each of said fixed blades is connected at its longitudinal edge facing the supply with one of said adjustable blades.
Claim 6
Dependent Claim
59 words
A grill according to claim 1 wherein said blades are adjustable in response to the temperature condition of the supplied gas, characterized in that the blades are arranged to diverge at continuously increasing angles, from the center of the grill when supplied with relatively cold gas and that said diverging angles increase additionally when supplied with relatively warm gas.
Claim 7
Dependent Claim
120 words
An inlet grill for supplying gases with varying conditions for control of dwelling rooms, comprising a plurality of elongated blades disposed with their edges facing the supply of gas, said blades constituting guide bars for guiding the gas stream, characterized in that at least of some of the blades are automatically adjusted to different angles relative to the flow direction in response to the varying conditions of the supplied gas, and other of the blades are fixed and are connected with said angularly adjustable blades, said adjustable blades being of a bimetallic material which can be bent or flexed to change the angular deflection of the gas stream through the grill in response to temperature changes in the gas stream.
Claim 8
Dependent Claim
120 words
An inlet grill for supplying gases with varying conditions for control of dwelling rooms, comprising a plurality of elongated blades disposed with their edges facing the supply of gas, said blades constituting guide bars for guiding the gas stream, characterized in that at least of some of the blades are automatically adjusted to different angles relative to the flow direction in response to the varying conditions of the supplied gas, and other of the blades are fixed and are connected with said angularly adjustable blades, said adjustable blades being of a bimetallic material which can be bent or flexed to change the angular deflection of the gas stream through the grill in response to temperature changes in the gas stream.
Claim 9
Dependent Claim
33 words
A grill according to claim 6, characterized in that the automatic adjustment of the blades at least partly alters the flow area of the nozzle in connection with the change of the angle.
Claim 10
Dependent Claim
29 words
A grill according to claim 6, characterized in that each of said fixed blades is connected at its longitudinal edge facing the supply with one of said adjustable blades.
Claim 11
Dependent Claim
143 words
An inlet grill for supplying gases with varying conditions for control of dwelling rooms, comprising a plurality of elongated blades disposed with their edges facing the supply of gas, said blades constituting guide bars for guiding the gas stream, at least of some of the blades being automatically adjusted to different angles relative to the flow direction in response to the varying conditions of the supplied gas, said adjustable blades being of a bimetallic material which can be bent or flexed to change the angular deflection of the gas stream through the grill in response to changes in thE temperature condition of the supplied gas, characterized in that the blades are arranged to diverge at continuously increasing angles, from the center of the grill when supplied with relatively cold gas and that said diverging angles increase additionally when supplied with relatively warm gas.
