Abstract: Twin metal billets (31) are fed to dual circumferential grooves (44) formed in a rotating wheel (43). The billets are advanced first to a edge-shaped gap which deforms the billets and are then advanced to a die (63). The die has a die opening with a circumferentially discontinuous, annular cross section. The metal from each billet merges in the die opening and exits therefrom in the form of a slit tube (34). The tube is then opened and flattened to form a flat strip (39) by advancing the slit tube over a forming member (38) having a progressively increasing width.

Abstract: An amorphous magnetic core is produced by wrapping cut strips of amorphous metal about a mandrel to form a distributed gap core. The cut strips are secured to the mandrel during assembly by wrapping the strips with amorphous metal ribbons that have been weakened in predetermined areas but not fully parted. After the core has been built to its desired size, the weakened ribbons are completely parted. This method of making an amorphous magnetic core produces a tightly wound distributed gap core without the need for a belt winder or specialized strip holding devices.

Abstract: A novel solenoid assembly is shown to include a solenoid having an armature and a delay member. The delay member delays movement of the armature from a first position to a second position until some desired condition occurs, for example, until a desired period of time has passed, until the solenoid is capable of generating a desired amount of force or until the current applied to the solenoid reaches a desired level. In a preferred embodiment, the delay member is a spring positioned to bias the armature against movement until the desired condition has occurred. In such an embodiment, the spring may be positioned to exert force against a shoulder formed on the armature. It is also preferred for the solenoid assembly to include a spacer, positioned between the solenoid and the mechanism being controlled by the solenoid. The spacer serves to space the armature from the mechanism when the armature is in the first position. In a further embodiment, the solenoid assembly further includes an extension member attached to the armature. In a still further embodiment of the invention, a body having a mass is attached to the armature for movement with the armature. In another embodiment, a method is provided for activating the mechanism including delaying the movement of the armature from the first position to the second position until such time as the armature force is greater than the maximum force necessary to activate the mechanism.

Abstract: An interface layer and method is provided that permits applications (10), without modification, to operate with any type of meter (30). The interface (20) comprises an abstraction layer and library or repository of descriptions specific to each meter type. The abstraction layer provides the capability to communicate with any meter (30) through a variety of applications (10). Upon receiving an application request, the abstraction layer retrieves the description for the particular meter type from the repository and processes the request. In this manner, only one data representation is needed for applications to communicate with a wide variety of meters (30).

Abstract: A cryostat for superconducting transformers is provided which includes an electrically non-conducting load bearing thermal insulation that is adapted for use with a superconducting transformer. The cryostat (10) also prevents the formation of closed loop stray currents on its outer case. The cryostat contains the winding sets (30) and other related electrical equipment of 3-phase electrical transformer as tap changer (28) and electrical leads (29). The cryostat with lid (14) generally comprises a heat insulated cryogenic tank having an outer wall (18), electrically non-conducting liner (22), and load bearing thermal insulation layer (20) disposed therebetween. The tank holds liquid or gaseous cryogenic coolant (34) into which transformer components are immersed, thereby reducing electrical resistance losses or wire losses and magnetic hysteresis losses or core losses. A plurality of passages allow the passage of the limbs or legs (36) from iron core (32) of the transformer through the cryogenic tank.

Abstract: A steel plate (130) of area greater than the area of the output of a nozzle (95) in a puffer gas interrupter (15-17) is fixed to but is spaced from the downstream end of the nozzle (95) and causes turbulence in the hot interrupter gases flowing through the nozzle (95) to improve mixing with cooler downstream gas.
