A piezoelectric transducer can be attached to a glass interstitial component or to a display panel of a multi-layer display in order to control the moiré interference.

Abstract: A distribution transformer having a slot-and-tab core frame assembly. The core frame (17) encloses a transformer core (11) having at least one phase and provides compression on the core yokes and end members of the transformer to bind the assembly together. First and second clamps (10, 24) of the core frame contain receiving slots (34) for the tabbed (18, 28), longitudinal side supports (20), creating an interlock when connected. For larger transformers, the tabbed side supports may be alternatively comprised of a subassembly of end plates, cams, and tabbed locking plates, encompassing a sturdy locking mechanism.

Abstract: A method provides a medium voltage radial drop winding for an open wound transformers. The method arranges a plurality of non-electrically conductive supports to extend outwardly from a periphery of an imaginary geometric shape so as to define an interior space. Each support includes a pair of opposing legs disposed in spaced relation and a bottom leg coupling the opposing legs to define at least one elongated slot between the opposing legs. Each slot has an open end. Conductive wire is dropped into the open end of each of the slots to substantially fill the slots and define at least one generally cylindrical winding segment carried by the supports.

Abstract: A dry-type network transformer has a core and coil windings insulated by a combustion-inhibiting gas. The combustion-inhibiting gas, core and coil windings are disposed within a hermetically-sealed enclosure. The combustion-inhibiting gas is air, an inert gas or a mixture of gases. The dry-type network transformer may be connected to a network protector. The network protector is further connected to a secondary network. The network protector prevents power from flowing from a secondary network to the primary side of the transformer. The dry-type network transformer is installed in a vault that is underground or at ground level. The dry-type network transformer may be suspended near the ceiling of the vault or installed at the base of the vault.

Abstract: Techniques for providing a play field reel glass enhancement on a gaming machine with mechanical spinning reels. A plurality of mechanical spinning reels are configured to indicate a gaming outcome for a wager game played on the gaming machine by a player. A light board located in front of the plurality of mechanical spinning reels lights up individual or groups of the light emitting elements. A graphic element on a reel glass is placed in front of the light board, creating the play field reel glass enhancement that is backlit by the light board to indicate gaming information to a player. A touch screen may be communicatively coupled with the reel glass to receive game input from the player, thereby making the play field reel glass enhancement interactive.
