Abstract: In a vertical glass drawing process, an edge guiding assembly (33) located between a glass forming apparatus (41) and a glass sheet separating apparatus (20) reduces horizontal motion of the glass ribbon (13) from which the glass sheets (11) are removed and results in the reduction of the difference in stress levels between the top and bottom edges of a glass sheet (11) made by the process. The edge guiding assembly also provides a reduction of the variation of stress levels between successive sheets of glass made by the vertical drawing process.

Abstract: A cigarette filter subassembly is manufactured from a filter member having absorbent material encased within an outer cover. A plunger is passed axially through the absorbent material such that a pointed leading end of the plunger displaces the absorbent material radially outwardly against the cover to form a liner of compressed absorbent material along the cover's inside surface. An inner surface of the liner surrounds a hollow axial opening which is to receive absorbent members and capsules inserted axially therein. The capsules are adapted to be broken by a smoker to release an additive material which modifies characteristics of tobacco smoke. An outer cylindrical surface of the plunger optionally carries a transferable binder material that becomes smeared onto the inner surface of the liner to form thereon a coating which is impermeable to the additive material released from the capsule.

Abstract: In a method for imprinting a layer of material, a nanotemplate is impressed into a material layer, and the nanotemplate is maintained impressed in the material layer until a geometric trench corresponding to geometry of the nanotemplate is formed in the layer, and the nanotemplate is then removed from the material layer. A nanotemplate geometric trench is repeatedly formed in the material layer by nanotemplate impressions in the layer, until a final desired imprint pattern is produced in the layer. Each nanotemplate geometric trench is characterized by an extent that is a fraction of an extent of the final desired imprint pattern. The material layer is maintained in a condition for accepting nanotemplate impressions continuously throughout the nanotemplate impression repetition.

Abstract: A process and apparatus is provided for enhancing the formation of a uniform population of hollow glass microspheres. A burner head is used which directs incoming glass particles away from the cooler perimeter of the flame cone of the gas burner and distributes the glass particles in a uniform manner throughout the more evenly heated portions of the flame zone. As a result, as the glass particles are softened and expand by a released nucleating gas so as to form a hollow glass microsphere, the resulting hollow glass microspheres have a more uniform size and property distribution as a result of experiencing a more homogenous heat treatment process.
