A system for monitoring coal flow through a coal delivery tube in a blast furnace fuel injection system is disclosed, which system automatically actuates a purge cycle for clearing accumulations of coal from a coal lance when a temperature drop indicative of an imminent blockage is detected. A method of controlling the purge system is also disclosed.

Methods and apparatus for foundation systems generally include a vertical support, a horizontal support configured to couple to the vertical support, and a composite material configured to couple to the horizontal support. The vertical support may be configured to resist fluctuation in soil elevation. The composite material may comprise a block material and a fibrous material.

A method of reinforcing a structure comprising a wall built on a reinforced concrete stem wall may include removing concrete from the reinforced concrete stem wall at an exterior of the structure to expose the reinforcing material within the stem wall and create a space within the stem wall. A degraded portion of the of the reinforcing material may be removed. A hold-down may be partially disposed within the wall inserting, from below the wall, such that an upper portion of the hold-down is disposed within the wall and a lower portion of the hold-down extends into the space within the stem wall. A horizontal composite bar may be coupled to the exposed reinforcing material and to the lower portion of the hold-down. A cementitious material may be disposed in the space within the stem wall, around the lower portion of the hold-down, and around the horizontal composite bar.

In an illustrative implementation, a system for video storage optimization analyzes user activity to determine how to optimally store video. In a preferred embodiment, a security system records video from a plurality of security cameras and stores the video at the security system and/or a server system, along with associated metadata. The server system monitors user activity, such as live and recorded video viewing behavior, and queries for videos. The server system collects user video viewing behavior statistics, determines trends, and stores both personnel-specific and enterprise-wide settings. An optimization engine analyzes the video info, personnel-specific settings, enterprise-wide settings, and user statistics to determine a storage factor for a video. The optimization engine then determines if a video meets storage factor thresholds and settings for compression or deletion.
摘要:
A process for purifying propylene oxide containing an unacceptable quantity of poly(propylene oxide) contaminant having a molecular weight of at least about 50,000, which comprises contacting the so-contaminated propylene oxide with a quantity of a substantially non-calcined diatomaceous earth for a time and under conditions sufficient to reduce the amount of such contaminant in such propylene oxide to acceptable levels, and recovering the purified propylene oxide product. Also, processes for making polyether polyols from such purified propylene oxide products, and for making high resilient flexible polyurethane foams from such polyols.
摘要:
The improved connector box assembly of the present invention includes mating male and female connectors, each of which is insulated in a novel manner to prevent manual touching, especially of the male probe during electrical connection, and also to prevent manual touching of the electrically live female conductor when not engaged with the male connector element. The female electrical receptacle is recessed within elongated neck-like electrical insulation means for disposition over one end of the female electrical receptacle and to permit relatively snug entry thereinto of the male electrical probe. The female electrical receptacle is a substantial distance front the orifice of the elongated neck means of such insulation. The female electrical receptacle electrical insulating structure is contained within an insulative housing which mates with an insulative structure at the base of the male electrical probes and which serves as an insulative collar extending a substantial distance along the shaft of the male electrical probes to mate with the female electrical receptacle electrical insulation means.
摘要:
A parking brake apparatus for use in a motor vehicle, mounted on a floor member which operatively connects a hand-operated brake actuator to a wheel brake is disclosed. The parking brake apparatus comprises a link member for reversing and transmitting an input force from the brake actuator to an output force on a cable linkage. The apparatus allows a hand operated parking brake actuator to be used in a vehicle with a cable linkage routed into the front of the actuator rather than into the rear of the actuator.
摘要:
Joint maker for the assembly of two or more pieces of stock about common interconnecting members. The joint maker includes a plurality of configured arms about common interconnecting members for either assembling stock at a right angle, or at other angles with respect to each other, whether there are two or more pieces of stock. The joint maker includes angularly inwardly extending cleats which extend from the arms, and arms extending from a common interconnecting member. Each of the cleats have an inwardly extending member.
摘要:
In one embodiment, video from a security camera is overlaid with small but visible indicators in each corner of the frame. The indicators may comprise an encoded value that can be decoded upon visual inspection by a user without the use of a computer. The encoded value may identify the camera such that a user knowledgeable about the format and sequence of the indicators can view the images and readily understand the identity of the security camera. In some embodiments, the indicators identify other information associated with the video such as the persons, objects, locations, conditions, times, or other data that is associated with the video.
