Abstract: A hand-held glass cleaning device is provided. Packaging for the device provides a cleaning section including a cleaning compartment and a drying section including a drying compartment. A wet medium capable of retaining moisture and releasing moisture upon application of pressure is disposed within the cleaning compartment. A cleaning fluid is in contact with the moisture retaining medium. A dry medium capable of absorbing and removing moisture and drying a surface is disposed within the drying compartment. The cleaning section and preferably the drying section include an end portion openable to expose a portion of the respective medium. A mid section of the device between the cleaning compartment and the drying compartment may be bendable. The device is particularly suitable for cleaning awkward surfaces such as interior windshields of automobiles.

Abstract: A glass fiber forming assembly is described which permits rapid change of a production fiber glass bushing. The system includes a secondary bushing and means to heat it as well as a glass delivery bushing permanently connected to a forehearth. The production bushings are physically out of contact with the forehearth.

Abstract: A method is provided giving a bundle of glass fiber strands improved integrity. A plurality of glass fiber strands are contacted with a fine, particlized, thermoplastic material in an amount up to about 0.5% by weight of the dried combined plurality of glass fiber strands in a forced gas chamber. The plurality of glass fiber strands containing the thermoplastic material is heated so that the thermoplastic material is softened on the plurality of strands thereby holding the strands together in such a manner that the plurality of strands can be processed without separating, but when the plurality of strands are chopped or woven the strands separate.

Abstract: A glass fiber sizing composition for the reinforcement of resin matrices is provided which comprises a homogeneous aqueous composition of two polyester resins. The first polyester resin is a water solubilized condensation cross-linkable, polyester resin, insoluble in aromatic solvents. The second polyester resin is insoluble but dispersible in water but insoluble in the first polyester resin. Thus, when the second polyester is blended with a water solution of the first polyester, a dispersion is produced. In this dispersion the water and the first polyester form the continuous phase and the second polyester forms the dispersed phase. A plasticizer and two silane coupling agents are also incorporated into the sizing composition. The first coupling agent is provided to promote adhesion between the glass fibers and the resin matrix and the second silane coupling agent is employed in the sizing composition to control the wetting of the glass fibers by the first silane coupling agent.
