Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
88 words
An apparatus for dispensing particles including: a substantially rigid container; a flexible container disposed interiorly of said rigid container housing the supply of particles therein; means for discharging particles received from said rigid container in a substantially downwardly direction; means for transporting a portion of the particles from the uppermost portion of said rigid container to said discharging means; and means for moving said flexible container relative to said rigid container in an upwardly direction to maintain a continuous supply of particles in communcation with said discharging means.
Claim 2
Independent Claim
88 words
An apparatus for dispensing particles including: a substantially rigid container; a flexible container disposed interiorly of said rigid container housing the supply of particles therein; means for discharging particles received from said rigid container in a substantially downwardly direction; means for transporting a portion of the particles from the uppermost portion of said rigid container to said discharging means; and means for moving said flexible container relative to said rigid container in an upwardly direction to maintain a continuous supply of particles in communcation with said discharging means.
Claim 3
Dependent Claim
33 words
An apparatus according to claim 1, wherein said transporting means includes a conveyor disposed in the uppermost portion of said rigid container to receive particles thereat and advance particles to said discharging means.
Claim 4
Dependent Claim
44 words
An apparatus according to claim 2, wherein said moving means includes means, in resilient engagement with said flexible container for urging the supply of particles in an upwardly direction so as to maintain a continuous supply of particles therein in contact with said conveyor.
Claim 5
Independent Claim
115 words
An apparatus for developing an electrostatic latent image recorded on a photoconductive member, including: a housing defining a chamber for storing a supply of developer material therein; means, disposed in the chamber of said housing, for advancing developer material into contact with the photoconductive member to develop the electrostatic latent image recorded thereon; means for storing a supply of toner particles therein; means for dispensing toner particles from the uppermost portion of said storing means into the chamber of said housing; and means for moving the supply of toner particles in an upwardly direction relative to said storing means so as to maintain a continuous supply of toner particles in communication with said dispensing means.
Claim 6
Independent Claim
115 words
An apparatus for developing an electrostatic latent image recorded on a photoconductive member, including: a housing defining a chamber for storing a supply of developer material therein; means, disposed in the chamber of said housing, for advancing developer material into contact with the photoconductive member to develop the electrostatic latent image recorded thereon; means for storing a supply of toner particles therein; means for dispensing toner particles from the uppermost portion of said storing means into the chamber of said housing; and means for moving the supply of toner particles in an upwardly direction relative to said storing means so as to maintain a continuous supply of toner particles in communication with said dispensing means.
Claim 7
Dependent Claim
53 words
An apparatus according to claim 4, wherein said dispensing means includes: means for discharging toner particles from said storing means in a substantially downwardly direction into the chamber of said housing; and means for transporting a portion of the toner particles from the uppermost portion of said storing means to said discharging means.
Claim 8
Independent Claim
144 words
An apparatus for developing an electrostatic latent image recorded on a photoconductive member, including: a housing defining a chamber for storing a supply of developer material therein; means, disposed in the chamber of said housing, for advancing developer material into contact with the photoconductive member to develop the electrostatic latent image recorded thereon; a substantially rigid container; a flexible container disposed interiorly of said rigid container housing the supply of toner particles therein; means for discharging toner particles from said rigid container in a substantially downwardly direction into the chamber of said housing; means for transporting a portion of the toner particles from the uppermost portion of said rigid container to said discharging means; and means for moving said flexible container relative to said rigid container in an upwardly direction to maintain a continuous supply of toner particles in communication with said discharging means.
Claim 9
Independent Claim
144 words
