Abstract: A solar heating panel unit is provided in the form of a plastic pouch having an internal chamber provided with a serpentine path. The pouch has two sides, one of which consists of a layer of anti-abrasive matte black plastic and a sealant inner layer of black medium density polyethylene film. The other side incorporates a reflective layer of aluminum foil. The pouch has inlets and outlets, whereat hardware fixtures are employed, consisting of threadably engaged parts having flanges between which is clamped a wall of the pouch. The pouch, or a plurality of such pouches, may be incorporated into systems wherein a cold water source is connected selectively through the pouch to a tank or through a boiler, whereof the boiler or the tank supplies a construction requiring heated water. Alternatively, the system may be such that the tank is excluded.

Abstract: A label is provided for a bottle in the form of a heat shrinkable sleeve made of oriented polyethylene. The label is made as a laminate having inner and outer layers. The outer layer has a coefficient of friction of less than about 0.15. The inner layer has a coefficient of friction of greater than about 0.4. The inner layer includes ethylene vinyl acetate. The layers are about 0.001 inches. The layers are connected by an adhesive, which is about 0.00005 inches thick. A plurality of sleeves can be formed from a planar strip wherein first halves of the sleeves are formed adjacent each other along half of the strip and complementary halves of the sleeves are formed adjacent each other along the other half of the strip, whereafter the strip is folded in half to bring the first halves into alignment with the complementary halves and the thusly constituted portions of the sleeves are heat sealed or welded together.
