Abstract: A coil spring assembly for connection with a separator body to apply a spring force to a grinding roll of a journal assembly to pulverize solid fuel. The coil spring assembly includes: a preload stud having a first end in communication with the journal assembly and an exposed opposite second end extending from the coil spring assembly; a spring adjustment bolt and bearing assembly being fixed relative to the preload stud extending therethrough; and a seal being substantially cylindrical shaped and flexible at least along a central axis thereof.

Abstract: An exhauster fan bearing assembly for a pulverized solid fuel firing system includes a pedestal housing having an opening at a top portion, the pedestal housing defining an interior space with access thereto through the opening; a bearing housing disposed at the top portion of the pedestal housing, the bearing housing having first and second openings disposed at opposite ends of the bearing housing; first and second bearing assemblies disposed at the first and second openings, respectively; a shaft extending through the bearing housing via the first and second openings, the shaft rotatable about a shaft rotational axis via the first and second bearing assemblies; and a sump housing operably coupled to a bottom of the bearing housing. The sump housing extends through the opening and into the interior space of the pedestal housing. The sump housing defines a reservoir for a lubricant in fluid communication with the first and second bearing assemblies.

Abstract: A polarizing beam splitter includes a multilayer polarizing film, a first cross-linked silicone gel layer disposed on the multilayer polarizing film, a first rigid cover disposed on the cross-linked silicone gel layer, and a second rigid cover disposed adjacent to the multilayer polarizing film.

Abstract: A grinder roll assembly (500) is provided herein. The grinder roll assembly (500) includes a grinder roll (505), a shaft (510) in a through bore of the grinder roll, a first tapered sleeve (615A), and a second tapered sleeve (615B). The first tapered sleeve (615A) fits between the shaft (510) and the grinder roll (505) in one direction, and the second tapered sleeve (615B) fits between the shaft (510) and the grinder roll (505) in an opposite direction to form at least one friction lock that mounts the grinder roll (505) to the shaft (510).

Abstract: Systems, computer-program-products, and methods for managing terminal services (TS) accounts and sessions for online utilization of hosted applications are provided. A system is operative to monitor a supply of available TS accounts and create TS accounts in response to detecting that the supply of available TS accounts is below a minimum number. When a request to access a TS session is detected, the system provisions a TS account for the user to immediately access the TS session without entering credentials. The provisioned TS account provides access and is associated with a unique profile. The system is also operative to receive the request to access the hosted application and decrypt credentials generated for the user. A method involves reading a username assigned to a user requesting access, locating the TS account associated with the username, identifying the language associated with the TS account, and launching the hosted application in that language.

Abstract: An exhauster is provided having an improved fan assembly for exhausting coal through an exhauster fan housing, the exhauster fan assembly being mountable within the housing on a shaft for rotation about a shaft rotational axis. The housing has an inlet generally aligned with the shaft rotational axis such that coal entering the housing through the inlet contacts the rotating exhauster fan and is redirected thereby along a radial outlet path. The exhauster fan assembly includes a plurality of blades and a hub having an outer surface, a free end, and a bore for receiving therein the free end of the shaft in an orientation in which the free end of the shaft and the free end of the hub are oriented in the same axial direction. The outer surface of the hub is radially outwardly spaced from the bore and the blades are mounted to the outer surface of the hub at uniform angular spacings therearound and project radially outwardly therefrom.
