Abstract: A spring-loaded ball valve includes a spring, a first pin, a second pin, and a handle. The spring is configured to apply pressure to the first pin and second pin when the ball valve is in both the fully open and fully closed positions. The spring applies maximum torque when the ball valve is in the fully open or fully closed position to ensure the valve remains in the fully open or fully closed position.

Abstract: A pressure-testing system for a tubular product. Preferably, the tubular product is a joint or a stand of production tubing. The pressure testing assembly includes a controller; a fluid reservoir configured to contain a test fluid; a pump in fluid communication with the fluid reservoir; a fluid hose having a first end configured to receive the test fluid from the reservoir, and a second end configured to be fluidically connected to a hydrotest tool for the tubular product; and a transducer. The transducer sends signals to the controller indicative of pressure within the fluid hose. The controller is programmed to automatically (i) store a pressure threshold value (T) and (ii) store a pressure test value (PT) such that when pressure in the fluid hose reaches (T) or when pressure in the fluid hose reaches (PT), the controller sends a signal to a diverter to divert a direction of fluid being pumped so that fluid is no longer pumped into tubular product.

At least one of the radiator, the radiator dilation layer, the beamformer, the beamformer dilation layer and the substrate support layer is fabricated at least in part by an AMT process.

Abstract: Techniques and apparatuses directed to improved pawl-latching devices are described in this document. The disclosed techniques and apparatuses provide pawl-latching devices with pawls structured to avoid the sinking and warping problems present in some conventional injection molding processes. In aspects, the pawl-latching devices include a pawl having at least one of a pivot member including a notch, a release feature on the pawl spaced apart from the front and sides of the pawl, a recess defined in the top of the pawl, and/or a recess defined in the bottom of the pawl.

Abstract: Provided is a process for the preparation of certain 1,4-bicyclo[2.2.2]octane derivatives. The new synthetic procedure involves treating 1,4-dimethylene cyclohexane with an oxidizing agent in the presence of a transition metal catalyst to afford an oxo-substituted bicyclo[2.2.2]octane species. This intermediate structure can then be further derivatized. The processes of this disclosure thus affords a novel and simplified means for the commercial production of a wide variety of bicyclo[2.2.2]octane derivatives.

Abstract: A rotating steering mirror assembly comprising a first wedge rotatable relative to a base and a second wedge rotatable relative to the first wedge to controllably tilt a mirror on an outward- or forward-facing surface of the second wedge. Respective motors can independently rotate the first and second wedges.

Abstract: A stud-mount insert configured to be releasably retained by a mounting-tab of a wire-tray assembly. The stud-mount insert includes a flange and a body configured to rotate about a longitudinal-axis of a mounting-stud. The flange is configured to overlay an aperture defined by the mounting-tab such that the mounting-stud extends through the aperture into the body. The flange is further configured to engage a top-surface of the mounting-tab proximate a perimeter of the aperture.

Abstract: Slide closure for a vessel that operatively contains molten metal, comprising: a slide housing including a recess receiving a first refractory closure plate; a slide unit including an opening receiving a second refractory closure plate; wherein at least one clamping mechanism is arranged to start the clamping of the corresponding refractory closure plate via an actuation of the at least one clamping mechanism when the slide unit is displaced relative to the slide housing and the first and the second refractory closure plates are distant apart from each other, essentially before the first and the second faces of the respective first and the second refractory closure plates are in contact under pressure.

Abstract: A row vision system modifies automated operation of a vehicle based on edges detected between surfaces in the environment in which the vehicle travels. The vehicle may be a farming vehicle (e.g., a tractor) that operates using automated steering to perform farming operations that track an edge formed by a row of field work completed next to the unworked field area. A row vision system may access images of the field ahead of the tractor and apply models that identify surface types and detect edges between the identified surfaces (e.g., between worked and unworked ground). Using the detected edges, the system determines navigation instructions that modify the automated steering (e.g., direction) to minimize the error between current and desired headings of the vehicle, enabling the tractor to track the row of crops, edge of field, or edge of field work completed.
