Aspects of the present disclosure provide techniques and apparatus for multiple physical resource block (PRB) operations for narrowband (NB) systems, such as NB internet-of-things (IoT). In one aspect, a method is provided which may be performed by a wireless device such as a user equipment (UE), which may be an NB-IoT device. The method generally includes performing a cell search based on one or more signals received in an anchor RB within a set of RBs available for narrowband communications with a base station (BS); determining a location of at least one additional RB available for the narrowband communications with the BS based on an indication received in the anchor RB; and performing narrowband communications with the BS using at least one of: the anchor RB or the at least one additional resource block.

A material application system includes a hopper assembly and a conveyor assembly. The hopper assembly includes an upper portion and a downcomer portion. Bulk material is loaded into the upper portion and passes through the downcomer portion. The downcomer portion may include a sail plate for agitating the bulk material to inhibit the formation of clogs in the bulk material.

A grain facility has a grain receiving station and a grain transport line with a grain elevator, a distributor with at least one input spout, and at least one grain bin. The grain transport line moves grain from the grain receiving station to one of the at least one grain bins and the distributor directs the grain to a selected bin of the at least one grain bin. The grain facility further includes an optical sensing system having at least one optical sensor positioned in the grain transport line at or before the distributor, wherein the optical sensing system senses the type of grain in the grain transport line. A control system determines if the grain passing through the grain transport line is suitable for the selected grain bin and produces an alarm if the grain in the grain transport line is not suitable for the selected grain bin.

A grain storehouse includes a granary, a grain loading system, and a grain unloading system. The granary includes multiple storages arranged in a network format. The bottom of each storage is a tapered structure with a tapered surface downward, and the bottom of the tapered structure provides a switchable blanking exit. The grain loading system includes a lattice girder structure, a plurality of conveyors and multiple hoppers. The grain unloading system includes at least one conveyor that is located under the blanking exit. The present invention improves the automaticity and efficiency of grain loading and unloading of the grain storehouse, so that the grain can be transferred quickly.

Embodiments of the invention provide a method for delivering a supply of one or more deicing and anti-icing agents for localized seasonal storage and application at a facility. In advance of a winter season, a deicing agent or anti-icing agent according to embodiments of the present invention may be provided by a provider to a receiver in a delivery quantity for storage at a localized storage location at a facility. A deicing agent may be a salt compound treated with an additive which reduces bridging of salt granules. The provider may provide multiple storage containers each filled with a delivery quantity of anti-icing agent and may provide multiple storage containers each filled with a delivery quantity of deicing agent to a receiver, as well as one or more delivery stations. After receipt of an initial quantity of a deicing agent or anti-icing agent, the receiver may deploy a delivery station and set up a storage container with the delivery station. The receiver may move a sprayer unit or a spreader unit to the delivery station for filling. Upon depletion of some or all of the contents of an anti-icing container or the contents of a deicing container, the receiver may contact the provider to request that the provider replenish the anti-icing agent or the deicing agent.

This invention quickly supplies a predetermined amount of powder from a hopper to a recoater. A powder supply apparatus includes, as its feature, a hopper, a powder spreader, a powder replenisher, and a pivoting unit. The hopper of the powder supply apparatus stores a powder. The powder spreader spreads the powder on a shaping surface. The powder replenisher of the powder supply apparatus is provided between the hopper and the powder spreader, and replenishes the powder spreader with a predetermined amount of powder. The pivoting unit of the powder supply apparatus causes the powder replenisher to pivot.
