Abstract: A tear-open bag is made of non-tearable synthetic resin and comprises a front side and back side formed from a single web of synthetic resin. The sides of the web are heat sealed together to form an end-to-end seam in the bag. The ends of the bag are heat sealed together, thereby forming a completely moisture resistant heat-sealed bag. One end closure of the bag is provided with a tear-propagating slit which can be readily manipulated by an adult to tear off a corner of the bag and thereby form a pour spout for dispensing the contents of the bag in a controlled manner. The slit is not readily or easily used by a child to open the bag, thereby rendering the bag child-resistant.

Abstract: A modular stackable receptacle for pool chemicals or the like includes an upper cover and a lower container portion. The cover includes a continuous rectilinear sidewall having a latch ring on an inner surface thereof. An upper surface of the cover includes a product dispensing pour spout which receives a removable closure cap. The upper surface of the cover also includes a raised crown portion which is coplanar with the closure cap. Both the closure cap and the crown portion have stacking and aligning projections which cooperate with respective recesses formed in the bottom wall of the container portion, which recesses facilitate stable stacking of the receptacles, one atop another. The container portion has a continuous sidewall which includes an upper outwardly projecting rim and an outwardly projecting catch ring that is adapted to interlock with the latch ring on the cover, whereby the cover cannot be readily removed from the container.

Abstract: A projectile for an industrial ballistic tool is formed from zinc or a zinc based alloy. The projectile has symmetry about a longitudinal axis and a rear portion of the projectile engages rifling, either within the barrel of the industrial ballistic tool or in a rifled extension, imparting ballistic stability. The projectile is particularly suited for high temperature industrial applications, such as removal of "clinkers" from cement kilns or lime kilns or removal of a plug when tapping an electric arc furnace, as used in the manufacture of metallic alloys such as ferrosilicon. The vaporization temperature of the projectile is sufficiently low that after effecting removal of the clinker or plug, the projectile vaporizes and does not contaminate the kiln, furnace or end product such as lime, cement or metallic alloy.

Abstract: A surface mount package to encapsulate one or more semiconductor devices has a standoff that maintains the thickness of solder columns bonding the package to an external circuit. The standoff either extends over or circumscribes a central portion of the package base. To enhance the thermal performance of the standoff, a solderable layer enhances soldering of the standoff to the external circuit.In alternative embodiments, the standoff contains a flange having a plurality of apertures useful for either mechanically locking an adhesive or for enabling irradiation of an adhesive by a light source. The standoff may contain protrusions for alignment, strength or circuit routing.

Abstract: There it is disclosed a chemical treatment for copper foil which imparts a dark brown to black color to the foil and improves the bond strength of the foil to a dielectric substrate without detrimentally changing the etching characteristics of the foil. The treatment includes depositing a nodular copper/nickel alloy layer on a surface of the foil. These nodules are 55% to 95% by weight copper and are electrolytically deposited using a pulse power controller.
