Abstract: A wireless device has at least a first modem and a second modern and at least a first SIM and a second SIM. The first modem supports a different level of service than the second modem. A processing system of the wireless device selectively reconfigures the connection of the first modem and the second modem to the SIMs. In a first mapping configuration, the first SIM is connected to the first modem and the second SIM is connected to the second modem. In a second mapping configuration, the second SIM is disconnected from the second modem, and the first SIM is disconnected from the first modem and is connected to the second modem thereby to obtain a different level of service for the first SIM than in the first mapping configuration.

Abstract: A modem is provided for a wireless device that is capable of providing service for at least two SIMs. The modem has at least a first set of modem components and a second set of modem components. The modem selectively reconfigures the arrangement of the plural sets of modem components. In a first configuration, the first set of modem components provides wireless connection service for a first SIM of the wireless device and the second set of modem components provides wireless connection service for a second SIM of the wireless device. This allows active wireless connections to be made on behalf of both SIMs simultaneously by the sets of modem components. In a second configuration, the first set of modem components and the second set of modem components provide wireless connection service for the first SIM.

Abstract: A variable speed separator drive for an agricultural combine includes a hub formed of chrome plated steel, and a movable sheave half carried by the hub. The movable sheave half is formed from nodular cast iron and includes an inside diameter with at least one spiral lubricating groove.

Abstract: A power transmission assembly for an agricultural machine includes a gearbox having an input shaft, and a torque sensing assembly having an axially fixed sheave, an axially movable sheave, a cam assembly interposed between the axially fixed sheave and the axially movable sheave, and a spring assembly coupling the axially movable sheave to the axially fixed sheave. The axially fixed sheave includes a hub portion having a tapered face extending increasingly outward from an inside diameter to engage a beveled shoulder of the input shaft. A nut is engaged with a threaded end of the input shaft, such that when tightened the nut forces the tapered face of the axially fixed sheave into engagement with the beveled shoulder of the input shaft.

Abstract: The present invention is a surge anchor mechanism which includes a main body, lower unit slidable in relation to the main body, and slip members. The slip members have at least one inclined end surface. The lower unit has an inclined surface forming a frustoconical shape wherein the slope of the surface complements the inclined end surface of the slip member. The lower unit is aligned along the axis of the main body and movable in relation to the main body along this axis. The slip members are biased towards the lower unit and movable transversely in relation to the axis of the lower unit. As a surge occurs in the well, the lower unit and the main body are forced towards each other. This causes the inclined surface of the lower unit to cooperate with and move along the corresponding inclined surface of the slip member forcing the slip member outward from the lower unit and into engagement with the well casing.
