Abstract: Systems and methods are provided for pitch determination. An example method includes obtaining an image depicting a structure, the image being captured via a user device positioned proximate to the structure. The image is segmented to identify, at least, a roof facet of the structure. An eave vector and a rake vector which are associated with the roof facet are determined. A normal vector of the roof facet is calculated based on the eave vector and the rake vector, and compared to a vector indicating a vertical direction such as gravity. The angle made out by the normal and a gravity vector may be utilized to calculate the pitch of the roof facet.

Abstract: A system for cooling plungers which operate in high pressure pumps. The system uses a plunger having a blind bore formed therein. The blind bore may receive a number of different objects, some of which are fixed to the plunger. A heat exchanger may be installed within the blind bore. The heat exchanger may have internal passages or openings which allow for the circulation of fluid within the blind bore, thus cooling the plunger. The heat exchanger may be formed of a material having a higher thermal conductivity than the material used to form the plunger. This allows the heat exchanger to cool the plunger more effectively than if the plunger were solid or filled with an empty air space. The heat exchanger may be sealed within the bore of the plunger, or exposed.

Abstract: A shear-assisted extrusion process and related apparatus can include establishing shear-assisted extrusion to form a first extrudate, suspending such extrusion, and re-starting extrusion with the same material or initiating extrusion of a different material or different billet of the same material to form a second extrudate, without requiring disassembly of extrusion apparatus or clearing of an extrusion die tool. A resulting combined extrudate can include a fused region joining the first extrudate and the second extrudate. Such processing does not require (nor generally involve) melting of feedstock materials and can be performed even if cooling occurs of the die tool and associated billet material between suspension of extrusion and re-start or initiation of subsequent extrusion. In this manner, downtime can be reduced or minimized, or extrusions can be formed having different material properties along their axial extent, as illustrative examples.

Abstract: A flangeless fluid end comprising a fluid end body releasably attached to a connect plate. The connect plate is attached to a power source using stay rods. The flow bores of the fluid end are sealed without threading a retainer nut into the walls of each bore. Instead, the flow bores are sealed by bolting a retainer to the fluid end body. Plungers to drive fluid through the fluid end body are installed within removable stuffing box sleeves. These sleeves are maintained within the plunger bores by the bolted retainers. A number of features, including the location of seals within bore walls and carbide inserts within valve structures, aid in reducing or transferring wear.
