Abstract: The present invention of a Bubbling Liquid Display includes a variable-pressure air source which injects air into a liquid within a panel at variable flow rates into an number of individual chambers to create a unique bubbling pattern for each chamber which includes large bubbles which move upwards within the fluid in the display, and smaller bubbles which move downwards within the fluid in the display. The display may be drained a single chamber at a time, eliminating the need to completely drain the display for maintenance, and also is substantially leak-proof, despite being tipped or knocked over. The display incorporates a fluid which resists evaporation, corrosion, and algae formation, despite being constantly bubbled or exposed to sunlight or other sources of heat, and which may be effectively recirculated through the display. The display is also adaptable to retrofit vending machines, as well as a variety of other useful items, such as point-of-purchase displays and wall-hangings.

Abstract: A method of forming a through-the-partition intercell connection between adjacent cell groups in a multicell, lead-acid storage battery. Plate strap lugs are positioned on either side of an aperture in a partition between adjacent cells. One of the lugs has a substantially flat face thereon abutting the partition while the other and opposing lug has a cavity formed in its partition-abutting face, which cavity is substantially axially aligned with the aperture during positioning. The battery is rotated 90.degree. such that the cavity-bearing lug lies beneath the flat-faced lug. The flat-faced lug is then arc welded through its center backside such that the melt formed flows by gravity through the aperture in the partition and into the cavity in the opposing lug. After the battery is inverted and the center backside of the cavity-bearing lug arc welded to fuse the lugs together, cold pressing the lugs together completes the connector forming process.

Abstract: An electrical connector including a plug member having a body portion including openings for receiving first contact members and an outer shell surrounding and spaced from the body member, a receptacle member having a body portion including openings for receiving second contact members corresponding to and mating with the first contact members and with the receptacle including a shell portion extending from the body portion and with the shell portion of the receptacle received within the space between the outer shell and the body portion of the plug when the plug and receptacle are mated, the outer shell of the plug including at least one internal tab and with the thickness of the outer shell increased in the area of the internal tab, the shell portion of the receptacle including at least one undercut portion on the outer surface and with the undercut portion including a front face extending across the undercut, and the internal tab locking in the undercut portion at the front face when the plug and receptacl
