Abstract: An improved method of assembling conventional scales, including bathroom scales, is provided by employing an improved spring for connecting the upper housing to the bottom pan. The upper housing may now be connected to the bottom pan with a simple downward force imposed on the improved spring thereby hooking the bottom of the spring to the bottom pan and mateably engaging the tapered top of the spring in an extruded hole in the upper housing. The improved spring is tapered at the top end to mateably engage the extruded hole in the upper housing and includes only one hook on the bottom end for engagement with the bottom pan. The improved spring enables easier and faster assembly of conventional scales thereby reducing labor and production costs.

Abstract: An improved reusable blister package is provided which consists of a base member, a top member and a label sheet. The top member mateably engages the opening of the base member. The label sheet seals the package shut after manufacture and prior to purchase. The package is opened by pulling the label sheet and the top member out and away from the base member thereby tearing the label sheet along the upper and side portions of the top member. The label sheet located along the lower end of the top member remains untorn and provides a hinge mechanism connecting the lower end of the top member to the lower end of peripheral flange of the base member. The improved package provides an outwardly facing label sheet that is entirely available for graphic presentations of logos and other product indicia.

A fabric cover overlies the core and is heat fused to the underlying core in the absence of adhesive.

Abstract: A clamp-type garment hanger with pads of resilient friction material on the inner clamping surfaces of the garment clamp assemblies to provide non-slip surfaces for garments such as trousers, skirts and the like. The non-slip surfaces on the clamp assemblies prevent the garments from slipping through the clamp asssemblies and falling onto the floor. The application of resilient friction material to the inner clamping surfaces applies equally to all types of clamp-type garment hangers. The resilient friction material used on the clamping surfaces comprises a block copolymer having discreet block segments of styrene monomer units and rubber monomer units.

Abstract: A lightning eliminating device for reducing the possibility of thunder strokes comprises a supporting base used for fitting semi-conductor rods, and a plural of semi-conductor rods fitted outwardly on the said base and having an elevation-angle or parallel with the ground reference, the two adjacent semi-conductor rods being electrically connected at the ends and separating from each other at the other ends at such a distance as will not cause a break-down voltage greater than the surface-wise flashover voltage generated on a single semi-conductor rod by thunder clouds. The semi-conductor rods may be made of the single variety of resistance material having a proper mechanical strength, or epoxy resin bars coated with semi-conducting materials such as zinc oxide, carbon black and resin. Even when there is a thunder stroke, the lightning eliminator will emasculate a strong stroke and reduce thunder current passing into the ground by 99%.
