Plastic end clips fused to plastic zipper

Abstract: A plastic clip is located at each end of a plastic zipper of a thermoplastic bag and fused with the ends of the profile elements of the zipper into a single mass by melting the clip to the zipper material.

Method for forming contacts

Abstract: A method and apparatus are provided for forming grid electrodes for solar cells, the method and apparatus essentially involving dispensing a viscous ink through a hollow pen tip onto a selected horizontally oriented solar cell blank, so that the discharged ink forms a ribbon or line on the blank, with the pen tip being spaced far enough above the solar cell blank so that it does not ride on the deposited ribbon or line, whereby the width and height of the written ribbon or line are not determined by the o.d. of the pen tip or any pressure exerted by the pen tip.

Method of producing an internally reinforced thermoplastic film and film and articles produced therefrom

Abstract: A method for producing an internally reinforced aeolotropic thermoplastic film web through coextrusion of two polymeric materials, and more particularly, a method of forming a film web possessing an enhanced tensile strength in at least the longitudinal or machine direction of the film web. A plastic film having internal striplike reinforcements entirely embedded within a matrix material is formed by the inventive method, and such film is utilized for various articles; for instance, plastic bags, bag components such as handles by liners, stretch wrap film, and the like.

Polymer foam process

Abstract: Thermoplastic foams of polystyrene, for example, are prepared with a blowing agent which is a mixture of an organic plasticizing blowing agent, such as pentane, and an atmospheric gas, such as carbon dioxide. Typically, such foams prepared with organic blowing agent alone were aged prior to thermoforming the foam into articles. Foams prepared with the mixed blowing agent of this invention exhibit the advantage of reduced atmospheric emissions on aging.

Method for producing zeolites

Abstract: As synthesized by previous methods, ZSM-5 or ZSM-11 zeolites are crystallized in the presence of substantial amounts of a nitrogen-containing compound. When synthesized in this way, they contain an organic ammonium cation as well as a metal cation such as sodium. To obtain a more active form, the sodium ion must be exchanged out. Such exchange, especially with ZSM-5 and ZSM-11, is difficult unless there is calcination of the zeolite to remove the obstructing organo compounds. By making these zeolites in the presence of (1) seeds of the desired zeolite, (2) mixtures of them with ammonium hydroxide and/or alcohol, (3) the alcohol per se or (4) mixtures of the alcohol with ammonium hydroxide, a product substantially deficient in organic ammonium cation is obtained. These products can be exchanged directly without any calcination.
