Abstract: A dynamoelectric device utilizes retaining members to prevent the windings from migrating into the air-gap between the stator and the rotor. The retaining members used in the device are axially self-locking, thereby preventing undesired axial translation of the retaining members during severe operating conditions of the dynamoelectric device.

Abstract: A rotor assembly for a rotating machine includes a substantially cylindrical main rotor body having an outer surface. A plurality of longitudinal ribs project from the outer surface of the main rotor body. A plurality of primary recesses are defined by adjacent ribs and a secondary recess is defined in the outer surface within at least one primary recess. A magnet is positioned within at least one primary recess, and a layer of adhesive between the magnet and the outer surface of the main rotor body fills the secondary recess. Magnet retaining elements in the form of either an encapsulation layer, star-shaped retainer or elongated retaining members may also be used. The magnet retaining elements may be used alone or in combination with the adhesive layer between the magnets and the main rotor body.

Abstract: A rotating machine includes an endshield assembly, a stator assembly, and a rotor assembly including a shaft. The endshield assembly includes an endwall having a substantially planar surface and a cylindrical endshield protrusion projecting along a longitudinal axis substantially perpendicular to the planar surface from a substantially central position on the endwall. The stator assembly is connected to the endshield assembly and has a substantially cylindrical main body extending from the endwall along the longitudinal axis substantially perpendicular to the planar surface. The rotor assembly is positioned within a central cavity of the stator assembly and arranged for rotation relative to the stator assembly. The shaft extends from the rotor assembly and passes through the cylindrical endshield protrusion. An outer surface of the shaft and an inner surface of the cylindrical endshield protrusion form a hydrodynamic bearing when the rotating machine is immersed in fluid.

Abstract: A dual brewing system for a vending machine in which a pair of separate brewers are mounted for simultaneous movement through a brewing and dumping cycle even though only one of the brewers is actually used to brew a beverage, such as tea or coffee, at a time. A filter paper feed mechanism is provided for one of the brewers used primarily for coffee. The paper feed mechanism is controlled so that it is only advance after the brewer which it is associated with is used and not when the other brewer is used.

Abstract: A coffee grinder mount assembly for mounting a coffee grinder to a housing by a support member. The assembly located adjacent a coffee bean storage bin for receiving coffee beans therefrom for grinding. The assembly having a mounting bracket for supporting the coffee grinder and fixedly attaching it to the housing. The mounting bracket including a sliding mechanism for moving the coffee grinder between an operating position where the coffee grinder may be operated to grind coffee or like food product suitable for brewing, and a servicing position where the coffee grinder is disposed remote from the storage bin. The coffee grinder being movable with the sliding mechanism in a linear direction away from the operating position and then pivotable with the sliding mechanism to the servicing position.

Abstract: A coffee bean delivery and grinding system for producing a charge of ground coffee comprising a bin and hopper for storing coffee beans, an auger being at least partially disposed in the bottom of the hopper, and a grinder having grinding wheels driven by a grinder motor. An auger motor is connected to one end of the auger for turning the auger to convey coffee beans from the hopper to the grinder. A control mechanism is provided for operating the grinder motor and the auger motor during the cycle of operation of the system. The end of the auger opposite the motor is located generally in an opening in the grinder housing such that the end of the auger is adjacent the grinding wheels for feeding coffee beans to the grinding wheels upon initiation of rotation of the auger.
