Abstract: Bus-bars 21, 22, 23 in a power installation (Fig. 1, not shown) are arranged coaxially and are apertured to permit flow of coolant between them, the thickness of bus-bar 21 being not greater than 15 mm. Sheaths 10, 20 and insulating spacers 24, 30 provide mechanical support. The insulation between the bus-bars is preferably liquid which may be circulated to dissipate heat for smaller power requirements, it may be replaced by air, supporting sheaths 10, 20 and bus-bars 21, 22, 23 being painted a dark mat colour, preferably red, to improve heat dissipation by radiation. The bus-bars may be of rolled sheet metal, in the form of two half-cylinders joined by welded bridges. Spacers 30 fit in the slots 25 between the half-cylinders, spacers 30 being accommodated with an amount of play in fluid-tight covers 11. To allow for expansion, lengths of the bus-bars 21, 22, 23 are joined by flexible laminated aluminium strips welded into slots (53) at the ends of the bus-bars (Figs. 5-8, not shown). L and T-section joints are effected by welding a prefabricated joint and the ends of the bus-bars 21, 22, 23 and sheath 10 to intervening cylinders 10L, 21L, 22L, 23L (Figs. 9, 10, not shown). The ends of the bus-bar assembly are modified by fitting L-joints (81, 91) to bars 22, 23 so as to present a row of electrical contacts (71, 80, 90) (Fig. 11, not shown).

Abstract: A pump, motor, compressor or prime mover includes a rotor 14 with a helical groove 14À1 meshing with replaceable teeth 50, on a wheel or pinion 20, the output being rendered variable by provision of inlet openings 24--24.3, which may be controlled by a valve (not shown). The output is least when working fluid is admitted through the opening 24 only and greatest when the said fluid is admitted through all four of the openings. A single outlet opening 52 communicates with a cavity 18 for the wheel 20 on the side thereof farthest from a face 58 of the housing with which the teeth 50 sealing engage, the position of the wheel being adjustable by appropriate manipulation of an eccentric bush 23 and/or screws 54 carrying balls 56. The groove 14À1 terminates at each end 14.2, as shown, to prevent leakage of working fluid therefrom. Alternatively, the inlet and outlet openings are formed in the motor, Fig. 6 (not shown). In another embodiment, Fig. 7 (not shown), a bore containing the rotor is open at one end thereof and the groove 14À1 is such that working fluid can enter it, or be discharged therefrom, by way of the said end of the bore, a single inlet, or outlet, opening (24.7) being formed in the side of said bore. In a further embodiment, Figs.4 and 5, the rotor has a disc-like configuration and two spiral grooves (14.5) are formed in one side thereof so as to mesh with the teeth 50, inlet and outlet openings being provided in a manner similar to that shown in Figs. 1 and 3.

Title: Electrical penetration assembly
IPC: H01B17/30
Filed: 1977-09-26
Abstract: An electrical penetration assembly is disclosed for providing a vapor and pressure seal between a conductor passing through two freestanding walls of a nuclear reactor containment which are subject to relative movement due to a seismic event. Penetration nozzles or tubes are placed through the walls of the containment when it is constructed. The penetration assembly is inserted into the nozzles and comprises a first subassembly fixed and sealed to a first penetration nozzle in the first wall and a second penetration subassembly in sliding or rolling engagement and sealed to a second penetration nozzle in the second wall. The sliding or rolling seal in the second nozzle allows the unrestrained reaction of the conductor to relative movement between the two freestanding walls during a seismic event without damage to the conductor or the penetration assembly. The penetration assembly also prevents the possibility of damage to either the conductor or the penetration assembly due to thermally induced stresses. The penetration assembly also minimizes installation difficulties resulting from unavoidable misalignments of the walls or the penetration nozzles mounted therein. Several embodiments of the invention showing different ways of effecting a sliding or rolling seal in the second penetration nozzle are disclosed.
