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: A device for aiding in the cross-hair alignment of the reticle of a gun-mounted telescopic sight wherein the gun includes at least one scope base for securing the telescopic sight. The device includes a light source for projecting a beam of light against a surface. The light source is mounted to the scope base of the gun. The projected light beam is modified to form a reference line which may be viewed through the telescopic sight. The projected reference line is automatically aligned with the barrel axis of the gun. One of the cross-hairs of the reticle of the telescopic sight may be compared with the aligned projected reference line and adjusted accordingly to align the cross-hairs with the barrel axis of the gun.

Abstract: A device for aiding in the cross-hair alignment of the reticle of a gun-mounted telescopic sight wherein the gun includes at least one mounting boss for securing the telescopic sight. The device includes a card having a viewing surface and a contact edge and at least one reference line located on the viewing surface and also aligned "true" with the contact edge. The contact edge of the card is adapted to be positioned in an abutting relationship with the mounting boss of the gun, independent of the telescopic sight so that the reference line on the card automatically aligns with the barrel axis and so that the viewing surface of the card lies adjacent to the reticle. The relative position of the card abutted onto the mounting boss allows the sighting hairline of the reticle to be compared with the reference line and properly adjusted.
