摘要:
A rotary feed structure for a gunite-conveying machine includes a polymeric body to resist sticking of gunite even if the latter includes silica fume, and even if it has set. The body has chambers in a circle. Preferably the body is urethane, self-bonded to a Ni-hard wear plate to eliminate radial leakage, and the mounting, (typically holes for studs), at least in part, is integral with the plate. A metal axial spacer is preferably next to the plate, but only within the innermost radius of chambers and with a sizable wall thickness. The body is preferably a feed-bowl type, with chambers formed as generally U-shaped pockets. A gunite machine using the polymeric feed structure also has a hopper, delivery tube, support and rotation of the feed structure, compressed-air for expelling the particulate material from the chambers into the tube, and provision for transporting the hopper, tube, body, and other apparatus. Chambers are selectively sealed to the expelling device and delivery tube. Dust emission is controlled by a short fill at the expulsion end of each chamber, and selective venting of residual pressure through the air-inlet end. Remaining dust, collected by a dry bag or atomizer nozzle, is preferably recycled to the bowl. New materials and procedures are used for fabricating the polymeric body.

Embodiments of the invention provide a novel and non-obvious method, system and computer program product for securing of leased resources on a computer. In one embodiment of the invention, a computer for securing resources may comprise at least one processor, a plurality of resources, wherein each resource is associated with configuration data and a programmable logic device connected to each of the plurality of resources. The programmable logic device may be configured for determining whether a resource is leased, reading un-encoded configuration data from a resource, and sending the configuration data to a first unit, if the resource is not leased. The programmable logic device may further be configured for reading encoded configuration data from a resource, decoding the configuration data, sending the configuration data that was decoded to a first unit, and logging use of the resource by the first unit, if the resource is leased.

This invention enables authenticated communications (transactions) to take place on a standard I2C bus without requiring modification of existing I2C devices. Read and write transactions occurring on the bus are authenticated using an Authentication Agent and a shared secret key. In addition to allowing verification of the legitimacy of the transactions, the authentication of the I2C transactions enhances the reliability and serviceability of the bus and devices on the bus by allowing the Baseboard Management Controller (BMC) to quickly determine and pinpoint errors.

The present invention is directed to a catalyst composition, comprising: (1) a catalyst precursor having the general structure MSXn wherein M is a transition metal selected from the group consisting of iridium, molybdenum, and tungsten; S is a coordinating ligand; X is a counterion; and n is an integer from 0 to 5; and (2) a phosphoramidite ligand having the structure wherein O—Cn—O is an aliphatic or aromatic diolate and wherein R1, R2, R3 and R4 are selected from the group consisting of substituted or unsubstituted aryl groups, substituted or unsubstituted heteroaryl groups, substituted or unsubstituted aliphatic groups, and combinations thereof, with the proviso that at least one of R1, R2, R3, or R4 must be a substituted or unsubstituted aryl or heteroaryl group. The present invention is also directed to activated catalysts made from the above catalyst composition, as well as methods of allylic amination and etherification using the above catalysts.

A high temperature dynamic seal and methods of assembly and use are presented. In one embodiment, the dynamic seal is provided as a rotating seal, which includes a stationary ring and rotating ring assembly, with a seal ring that is positioned between the stationary ring member and the rotating ring assembly. In some embodiments, one or more high temperature seals create a seal between the stationary ring member and a device in which the dynamic seal is used. Similarly one or more high temperature seals create a seal between the rotating ring assembly and a rotating shaft of the device. In one aspect, one or more of the high temperature seals are formed from a metallic material with various cross-sectional shapes.

An automated, multi-tiered system and process for storing objects includes the ability to efficiently store and retrieve objects. The system may include a number of object entrance ports, object exit ports, elevators, horizontal transportation systems, and storage levels, each storage level including a number storage bays. The horizontal transportation systems may move objects after they have been mounted on frames. The movements of an object entering and departing the multi-tiered system may be based on ordered, anticipated tasks, for the purpose of enhancing the system layout and operation.
