Title: Method and apparatus for making optical glass articles
IPC: G02B6/00
Filed: 1979-06-07
Abstract: A glass optical waveguide filament preform is prepared by chemical reaction of vapor ingredients within a glass substrate tube. As the reactants flow through the substrate tube 52, a hot zone 54 traverses the tube to cause the deposition of sooty reaction products 44' in the region of the hot zone, the soot being consolidated to glass layer 48'. A baffle tube 50 extends into that end of the substrate tube into which the reactants flow. The baffle tube 50, which traverses the substrate tube along with the burner 56, ends just short of the hot zone 54 so that no soot is deposited thereon. A gas flowing from the baffle tube creates a gaseous body or mandrel 66 which confines the flow of reactant vapors to an annular channel adjacent the substrate tube wall 52 in the hot zone, thereby increasing deposition rate and efficiency.

Title: Method for producing mixtures of thermoplastic synthetic materials and mineral or organic charge materials,apparatus for the implementation of the method and material produced thereby
IPC: B01F23/70
Filed: 1981-05-08
Abstract: In a method for producing mixtures of thermoplastic synthetic materials and mineral or organic charge materials, the materials are vacuum mixed and compressed. According to the invention, the mixtures of synthetic materials and charge materials are already homogeneous in a powder state. They are also resistant without granulation to disaggregation, they are stable and can be shaped as products. Moreover, the rigidity must be obviously high but without fragility. The values of the resistance must approach those of the pure synthetic material. Finally, commercial advantages must be attained. To these purposes, the charge materials must be electrically or electrostatically charged before and/or during the mixing with the synthetic materials. As an alternative, this can also be achieved with the synthetic material and even, for instance, through a continuous stirring within an electric field. The charge remains stable during a long period allowing a previous treatment and a storage of the charge material separated from the mixing operation. A combined loading and mixing reactor, together with an installation (57) for producing a strong grinding of the content, is also part of the invention.

Title: Method of bonding synthetic resin fastener having fusion heat to flat film.
IPC: B31B19/90
Filed: 1982-05-27
Abstract: A method of and apparatus for fusion bonding a continuous synthetic thermoplastic resin fastener strip having a fastener profile portion and a base portion opposite the profile, to a continuous film substrate. The substrate is advanced continuously through a bonding zone. Continuous direct transit of the fastener strip is effected from thermoplastic extruder downwardly through a short distance to the bonding zone, so that in the short transit distance the fastener strip will retain substantial residual thermoplastic fusion temperature. The fastener profile portion is chilled while the strip is in transit to the bonding zone, solidified and stabilized, but the base portion is left at sufficient residual fusion temperature to remain thermoplastic to the bonding zone where assembly of the strip and substrate is effected by fusion bonding of the base portion to the substrate. An annular rotary heating surface may be applied to a narrow locally limited longitudinal area of the substrate for supplying to such area fusion promoting heat in the bonding zone, such area being aligned with the fastener strip in the assembly. The longitudinal area may be stretched by the rotary heating surface.
