Abstract: The subject matter disclosed herein provides methods for controlling loads in an IP network that is divided into one or more zones and/or subzones. In one aspect, there is provided a method that can associate a plurality of controllers with one of a plurality of zones. Each controller can be connected to one or more loads. The method can associate each controller with an address. The address can include a network address and a host identifier. The network address for each controller in a first zone can be the same. The method can transmit over a network a control message to each controller in the first zone. The control message can cause one or more operational parameters of the loads connected to each controller in the first zone to change. Related apparatus, computer program products, systems, techniques, and articles are also described.

Abstract: In a bulk material analyzer in which bulk material is received in an activation region between a pair of neutron sources laterally disposed on one side of the activation region for emitting neutrons for bombarding the bulk material within the activation region to cause gamma-rays to be emitted from the bombarded bulk material and a pair of gamma-ray detectors laterally disposed on another side of the activation region for detecting gamma-rays emitted from the bulk material, a primary neutron moderator is disposed about the neutron sources for reducing the velocity of the emitted neutrons; and a secondary neutron moderator is disposed about the primary neutron moderator for further reducing the velocity of the neutrons and is further disposed adjacent the lateral edges of the activation region for channeling and reflecting the neutrons into the activation region.

Abstract: A magnetically shielded room has four walls, a floor, and a ceiling. One of the walls has a doorway therethrough, and a sliding door is provided to close the doorway. Each of the four walls, the floor, the ceiling, and the door is formed of at least one layer of electrically conductive material to exclude radio frequency energy from the interior of the room, and at least one layer of high magnetic permeability material to exclude magnetic fields from the interior of the room. Preferably, at least the wall with the doorway therethrough and the door are formed of two electrically conductive plates and a layer of high magnetic permeability material on each of the plates, the electrically conductive plates of the wall being spaced sufficiently far apart that the sliding door slides into the space between the plates when the doorway is opened.

Abstract: A bulk material analyzer of the type in which the bulk material is transported through the material analyzer assembly on a conveyor belt between at least one radiation source and at least one radiation detector, includes a plurality of lower and upper modules that contain radiation shielding material and are so shaped as to define a passageway for the conveyor belt between the upper modules and the lower modules when the upper modules are placed on the lower modules. A primary centrally located lower module also includes the radiation sources and a primary centrally located upper module also includes the radiation detectors. Some of the outwardly located modules contain less radiation shielding material. The radiation shielding material includes a plurality of personally portable blocks. The conveyor belt is supported by compressed air passed through central upper wails in the outwardly located lower modules.

Abstract: A radioactive source is mounted at one end of a rod and a ball-shaped coupler is disposed at the other end of the rod. An apparatus for handling a plurality of radioactive sources respectively mounted at one end of a plurality of rods having a ball-shaped coupler disposed at the other end of each said rod includes a shaft having a canister at one end of the shaft and a clip at another position on the shaft. The canister defines a plurality of compartments for respectively receiving a plurality of said mounted radioactive sources. The clip defines a plurality of chambers for respectively receiving a plurality of the ball-shaped couplers. The rods are flexible and semirigid and the distance between the canister and the clip is such in relation to the distance between the radioactive source and the ball-shaped coupler on the rod that the rods must be flexed after the radioactive sources are received in the compartments in order to insert the ball-shaped couplers into the chambers of the clip.
