10 results about "Pounds per square inch" patented technology

The pound per square inch or, more accurately, pound-force per square inch (symbol: lbf/in²; abbreviation: psi) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch. In SI units, 1 psi is approximately equal to 6895 N/m².

Packing for high-pressure valves

The valve bonnet defines a packing box having an interior surface roughness average (Ra) of 0.15 or less, e.g., 0.10 to 0.15. A plurality of polytetrafluoroethylene (PTFE) packing rings reside within the packing stack. Packers are bolted to the bonnet and extend into the packing box. The packers are configured to apply packing pressures to the packing, e.g., 100 megapascals (MPa) to 200 MPa. Such a configuration may enable high-pressure valves, e.g., valves capable of holding pressures up to 10,000 pounds per square inch (PSI) or up to 15,000 PSI.

Projectiles, reactive compositions for projectiles and articles containing the reactive composition

ActiveUS12680797B2TitaniumLethality
A projectile including a reactive composition is disclosed. The reactive composition includes at least one fuel comprising a titanium-boron composite, at least one oxidizer, and at least one metal hydride. When the projectile penetrates through a surface of a target having a volume of 0.2 m3, the reactive composition is configured to cause, behind the surface of the target, at least one of an overpressure of greater than 36 pounds per square inch (psi) or an incendiary effect duration of greater than 70 milliseconds. The reactive composition may be configured to partially or entirely surround a pin or penetrator. The projectile may lack a pin or penetrator, and the reactive composition is contained within a metal tube or cup configured to travel toward, within, and / or behind a surface of the target, wherein the process produces a punch out from the target, thereby acting as a second projectile, which enhances lethality.

Octagonal Ultra-High Performance Concrete Prestressed Pile System for Deep Foundation Applications

An octagonal Ultra-High Performance Concrete prestressed pile system for deep foundation applications utilizes an octagonal cross-sectional geometry with 30-inch flat-to-flat external diameter and central void of 26-32 inches diameter optimized for material efficiency and structural performance. The system employs Ultra-High Performance Concrete with compressive strength exceeding 18,000 pounds per square inch and conventional carbon-steel prestressing strands to provide structural capacity equivalent to steel pile systems. The octagonal geometry with central void targets approximately one cubic yard of UHPC per fifty feet of pile length, enabling direct economic comparison with steel alternatives while providing enhanced durability and reduced dead weight by up to 75%. The system includes modular splice connections for extended length capability and addresses multiple market sectors including high-rise buildings, bridges, industrial facilities, and general infrastructure projects. The octagonal configuration with central void provides superior material utilization compared to conventional square and circular pile geometries while maintaining excellent driving characteristics and structural performance.

Methods of forming blocks utilizable for building construction out of non-recyclable plastic waste raw material

A method of forming blocks having dimensional uniformity thereacross associated with building construction includes shredding, via a shredder, a non-recyclable plastic waste raw material having a specific dimensional length and a height into a number of strips having a uniform dimensional width of 0.120 inches to 1 inch, and weighing the number of strips at a weigh apparatus. The method also includes isolating and batching the number of strips collected and weighed, and compressing the isolated and batched number of strips in a compression chamber to form a block based on steam-sanitizing the isolated and batched number of strips in the compression chamber with steam having a temperature varying from 220° F. to 850° F. and a pressure of 30-500 Pounds per Square Inch (PSI) and introduced intermittently across regions of the compression chamber to solely activate a base polymer of each of the isolated and batched number of strips.

Wooden wall panels and methods for forming same

A method for forming a wall panel may involve arranging at least first and second spacers on a first outer wood layer, with an adhesive being disposed between the first outer wood layer and the first and second spacers, so that a gap is formed between the first and second spacers. Pressure of least fifty pounds per square inch (psi) may be applied to the first outer wood layer to cause formation of a tight bond between the first outer wood layer and the first and second spacers as the adhesive at least partially cures.
