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: An improved elongate drain trap made of a material having a low index of heat conductivity and having inlet and outlet end portions and a substantially U-shaped central basin portion below and extending between the end portions and in which water is contained and sometime freezes to establish an ice plug; the improvement comprises an elongate insert made of material having a high index of heat conductivity and having an upper end portion in the inlet portion of the trap and a lower end portion extending through the central basin portion of the trap. The insert functions to absorb heat from hot water deposited in the inlet portion of the trap and to conduct that heat through the basin portion of the trap where it melts a sufficient portion of an ice plug formed therein to establish a flow passage for water through the plug.

Abstract: The invention relates to polygonal flank sockets, or drives, for correspondingly shaped fasteners which impart the torque turning load thereto, and more particularly relates to sockets and socket drives adapted to accommodate nut type fasteners that are complements thereof, of improved construction to more effectively sustain nut turning loads. The present arrangement insures surface-to-surface flat engaging contact between the splines and flanks of the nut fasteners for any purpose requiring torque or turning loads. In the present invention, straight surface-to-surface contact for load transmitting action is assured, whereby greater torque loads can be transmitted with the wrench socket embodying the teachings of the present invention.
