Title: Nuclear reactor coolant pump and passive parking sealing device thereof
Inventor: Guo hui cong
IPC: F04D29/12
Filed: 2017-05-16
Abstract: A passive parking sealing device (30) for a nuclear reactor coolant pump. The passive parking sealing device (30) comprises a complete sealing ring (40) that can be in a starting position and a non-starting position, and a complete limit ring (50) that softens when a state conversion temperature is reached. When the limit ring is in a temperature below at a state conversion temperature, the sealing ring surrounds in the circumferential direction of a pump shaft (18) of a nuclear reactor coolant pump and maintains a clearance with the pump shaft under the support of the limit ring. When the limit ring is in the state conversion temperature or in a temperature higher than the state conversion temperature, the limit ring is softened or melted, and the sealing ring loses the support of the limit ring and tightly holds the pump shaft, so as to prevent the reactor coolant from flowing along the pump shaft. The passive parking sealing device for a nuclear reactor coolant pump is only provided with a sealing ring providing the sealing effect and a limit ring providing the limit function, the movement of the sealing ring from the non-starting position to the starting position does not depend on external force, and the entire sealing has the advantages: the structure is simple and the sealing is reliable.

Title: Cobalt catalysts and precursors therefor
Inventor: RICHARD JOHN MERCER

Abstract: A cobalt catalyst precursor is described comprising cobalt oxide crystallites, with an average size as determined by XRD of 6-18 nm, disposed within pores of a spherical titania (TiO2) support with a particle size in the range 100-1000 µm. The precursor has a pore volume of 0.2-0.6 cm3/g and an average pore diameter of 30-60 nm, hence the precursor has a ratio of the average cobalt oxide crystallite size to the average pore diameter in the range 0.1:1 to 0.6:1. The cobalt content is preferably 5-20 wt%, the volume-median diameter of the precursor is preferably 300-500 µm and the titania support used can contain >50% anatase. The precursor can comprise 1-25 wt% additive metals e.g. manganese and 0.01-1 wt% promoter metals e.g. ruthenium. To prepare the precursor, an impregnation method using cobalt nitrate and calcination in a fluidized bed reactor can be used. The catalyst precursor may be reduced to provide catalysts suitable for use, preferably with a suitable annular carrier, in Fisher-Tropsch reactions. The resulting catalyst can also be subjected to a passivation treatment or encapsulated in a hydrocarbon wax.

Title: Endpoint security
Inventor: CHRIS DOUGLAS KRAFT
IPC: H04L47/2475
Filed: 2018-08-08
Abstract: An enterprise security system is improved by managing network flows based on an application type. When a network message having an unknown application type is received at a gateway, firewall, or other network device/service from an endpoint, the endpoint that originated the network message may be queried for identifying information for the source of the network message and the application type may be determined, or the endpoint may periodically communicate application type information to the network device in a heartbeat or other periodic communication or the like. The network message may be managed along with other network traffic according to the application type. In another aspect, an endpoint can protect computing objects on the endpoint against tampering with a secure cache in the kernel space of the endpoint operating system.
