Abstract: Dynamo electric machines and stators for use in such machines are provided. The stators comprise plates configured to be substantially flat and a plurality of spaced apart projections or teeth extending away from the plate and, together with the plate defining a plurality of slots therebetween. The stators comprise masses of metal particles. Using stators made from such metal particles provides enhanced machine efficiency, which is believed to be because of reduced eddy current effects in the stator. Motors including rotors having generally flat arrays of permanent magnetic poles and such stators which are spaced apart from and generally facing the permanent magnetic poles and have a plurality of magnetic windings, and pumps powered by such motors are included within the scope of the present invention.

Abstract: A pump including a pump casing having an inlet and an outlet, and an impeller having a rotary axis and being rotatably mounted within the pump casing for rotation about the rotary axis is provided. The impeller is configured and positioned relative to the pump casing so that the rotation of the impeller is effective to urge fluid from the inlet to flow through the outlet. A rotor assembly, coupled to and rotatable with the impeller, is provided with a plurality of permanent magnetic poles which are arranged in a generally flat array. A stator assembly is spaced apart from and generally facing the generally flat array of magnetic poles and includes a stator and a plurality of magnetic windings positioned and adapted to effect rotation of the rotor and the impeller upon energization thereof. A bulkhead is positioned between the rotor and the stator. The bulkhead includes a centrally located mounting feature.

Abstract: A delivery system comprising a pump connectable to a source of pumpable material, such as flowable condiment, and a control valve including a valve body and a valve element. The valve body has an inlet coupled to the pump to receive the pumpable material from the pump, a resiliently expandable portion chamber, an inlet passage extending from the inlet to the portion chamber, an outlet and a discharge passage extending from the portion chamber to the outlet. The valve element is movable in the valve body between a charging position in which the valve element blocks the discharge passage and does not block the inlet passage so the pump can supply the pumpable material under pressure to the portion chamber to resiliently expand the portion chamber and a discharge position in which the valve element blocks the inlet passage and does not block the outlet passage so the portion chamber can resiliently contract to move the pumpable material from the portion chamber toward the outlet.

Abstract: An aircraft fueling nozzle has a body with a bearing sleeve mounted within the body. The nozzle has a poppet having a stem which is guided by the bearing sleeve. A seat is mounted in the nozzle body for forming a seal with the poppet head. The seat is retained in the body by a resilient lip which encompasses the seat projecting outward and interacts with an inwardly projecting lip on the body. The nozzle has a linkage for moving the poppet including an actuator located upstream of the bearing sleeve which is connected to an arm which overarches the bearing sleeve and is connected to the poppet. The actuator includes a crank which is connected to the arm and an actuator shaft which connects to the crank by interfitting splines. The nozzle further includes a swivel for rotatably coupling the nozzle body to a fuel supply. The swivel includes a replaceable annular bearing ring. The nozzle includes recesses for receiving the lugs of an aircraft fueling flange to secure the flange to the nozzle.

Abstract: A ball valve has a housing which rotatably carries a ball. The housing has inlet and outlet ports. The ball has two ports which may be rotated to align with the housing's ports. The ball carries a cartridge in a cartridge compartment located transverse to the ball ports. The cartridge has inlet and outlet ports between which a cartridge flow passage is defined. A strainer is located within the cartridge flow passage. The ball and cartridge may be rotated to an orientation in which the ball ports are substantially transverse to the housing ports, from which orientation the cartridge may be extracted from the ball and housing and the strainer may be removed from the cartridge.
