Abstract: A thermoplastic bag includes duplicative seals. In particular, in one or more implementations, a thermoplastic bag includes a first seal and at least a second seal reinforcing the same area of the thermoplastic bag. For instance, in one or more implementations, the thermoplastic bag includes multiple seals along each side edge or along the hem. If one seal fails, the other seal(s) can remain in place to prevent leaks. Thus, the duplicative seals of the thermoplastic bag can provide reinforced strength and desired aesthetics.

Abstract: Thermoplastic bags with phased deformation patterns are described. In particular, one or more implementations comprise thermoplastic bags with ring rolling, SELFing, or other deformation patterns phased or aligned relative to the sides of the bags. The phased deformation patterns can allow for reducing or eliminating deformation patterns in areas of the thermoplastic bag in which side seals or other seals are formed. Additionally or alternatively, the phased deformation patterns can provide for zones that provide differing properties (e.g., functional or aesthetic). Such zones can vary aligned along a width of the thermoplastic bag and optionally also vary along a height of the thermoplastic bag. The differing zones can provide the thermoplastic bags with phased deformations that provide leak prevention, liquid containment, and other benefits.

Abstract: Polychromatic glass articles and methods of producing such articles are disclosed in which the glass is activated by exposure to ultraviolet radiation and contains as a sensitizing agent an oxide of copper, samarium, terbium, praeseodymium, or europium.

Abstract: The instant invention is drawn to glass-ceramics especially designed for the fabrication of radomes, wherein cordierite is the predominant crystal phase but which also contain minor amounts of cristobalite, magnesium-aluminum titanate, and rutile, having overall compositions consisting essentially, expressed in weight percent on the oxide basis, of about______________________________________ MgO 15-18 Al.sub.2 O.sub.3 21-25 SiO.sub.2 48-53 TiO.sub.2 9.5-11.5 As.sub.2 O.sub.

Abstract: An adaptor for use in a woodworking machine that utilizes a conventional router as a cutting means. The adaptor is mountable upon the router support carriage of the machine and enables the router to be used to cut a template generated from the profile of a preexisting part or an easily prepared pattern from which new parts can be produced thereby considerably expanding the usefulness of the machine.
