Abstract: A device for dispensing a material having: a first surface with an orifice; a second surface opposite the first surface; a first endface comprising an annular opening; a second endface opposite the first endface; a cavity defined by the above. An actuator is anchored to the second surface and has at least a portion of a pressing pad extending through the orifice in the first surface. An inner side of the second surface comprises a contoured portion within the cavity, the contoured portion having a first end positioned toward the second endface and a second end positioned toward the first endface, wherein the contoured portion has a maximum height at or near the first end, and a minimum height at a position between the first end and the second end.

Abstract: A connection assembly for automated lifting and positioning of a chiksan or other fluid conduit in proximity to a fluid inlet of a device such as, for example, a cement or hydraulic fracturing head. Once a chiksan or other flow line is positioned in a desired location, a secure connection is made between the outlet of the chiksan or other fluid conduit and the fluid inlet including, without limitation, when the device is positioned at an elevated location above a rig floor.

Abstract: In an example, there is disclosed a method and system for calculating an object's trust level for security purposes based on prevalence in a context-aware network. In an embodiment, as objects are accessed, a client queries a domain master such as a reputation server to evaluate the object's reputation. The domain master may maintain a prevalence-based reputation database, which may be updated as new clients report object prevalences.
