A mechanical latch assembly includes a supporting frame, a locking latch, an actuation arrangement and a safety lock arrangement. The locking latch is slidably mounted on said supporting frame in longitudinally movable manner. The actuation arrangement includes an actuation handle pivotally connected to said supporting frame to longitudinally drive said locking latch moving between a locked position an unlocked position. Moreover, the safety lock arrangement includes a locker member movably mounted on said supporting frame, wherein said locker member has a slider slot formed thereon to define a pusher surface and an opposed retracting surface, and a thermal activated arm substantially extended from said supporting frame to slidably pass through said slider slot of said locker member at a safety temperature, and adapted to deflect to push said locker member at said pusher surface at an elevated operation temperature.

A two component catalyst activator comprises: 1) a Lewis acidic organoboron (or an orgonoaluminum) component; and 2) a component defined by the formula AOSO2R wherein A is a pseudo cationic group and R is a hydrocarbyl or substituted hydrocarbyl. The catalyst activator is used in combination with a transition metal catalyst for the polymerization of olefins. The catalyst activator provides improved catalyst activities. It is especially useful in solution polymerizations because of desirable solubility characteristics in comparison to the borate salts used in prior activators.

The well reference apparatus and method of the present invention includes a reference member preferably permanently installed within the borehole at a preferred depth and orientation in one trip into the well. The reference member provides a permanent reference for the location of all operations, particularly in a multi-lateral well. The assembly of the present invention includes disposing the reference member on the end of a pipe string. An orienting tool such as an MWD collar is disposed in the pipe string above the reference member. This assembly is lowered into the borehole on the pipe string. Once the preferred depth is attained, the MWD is activated to determine the orientation of the reference member. If the reference member is not oriented in the preferred direction, the pipe string is rotated to align the reference member in the preferred direction. This process is repeated for further corrective action and to verify the proper orientation of the reference member. Upon achieving the proper orientation of the reference member, the reference member is set within the borehole and the pipe string is disconnected from the reference member and retrieved.

A system for distributed phased array multiple input multiple output (DPA-MIMO) communications is disclosed. The system includes beamforming (BF) modules. Each BF module comprises a beamforming antenna, a downconverter that downconverts a beamformed antenna radio frequency signal to an intermediate frequency signal, and an upconverter that upconverts an intermediate frequency signal to a radio frequency signal and sends said radio frequency signal to said beamforming antenna for transmission. The system further includes intermediate frequency (IF) radios. Each IF radio comprises a downconverter that downconverts an intermediate frequency signal sent from a BF module to a baseband signal, and an upconverter that upconverts said baseband signal to an intermediate frequency signal that is transmitted to a beamforming module. The system can be designed for a wearable virtual reality (VR) device, a VR base station, an automotive vehicle, an aerial vehicle, a high altitude platform (HAP) system, and a foldable handheld device.

In embodiments, the present invention relates to liquid formulations containing hydrophobic, biodegradable polymers dispersed within a Non-aqueous Organic Solvent Delivery System (NOSDS) that is designed to coat fertilizer granules with a hydrophobic film utilizing simple application equipment such as mixers, blenders and tumblers. This film can impede the dissolution of fertilizer components by water improving fertilizer efficiency. The NOSDS can be aprotic solvents, protic solvents and mixtures of protic and aprotic solvents which are environmentally friendly, have flashpoints above 145° F., and are inherently rated safe for contact with humans and animals. The hydrophobic polymers are the reaction product of aldehyde(s) and nitrogen containing compounds.
摘要:
An improved solvent system for the formulation and application of N-alkyl thiophosphoric triamide urease inhibitors. These formulations provide safety and performance benefits relative to existing alternatives and enable storage, transport and subsequent coating or blending with urea based or organic based fertilizers. These formulations are comprised primarily of environmentally friendly aprotic and protic solvents (particularly dimethyl sulfoxide and alcohols/polyols) to stabilize the urease inhibitor.

Disclosed are an application management method and device, applied to a first device connected to a second device. The method includes mapping at least one application in the second device, to obtain at least one corresponding application identifier; detecting a first operation; when the first operation satisfies a first preset condition, determining an application identifier of a first application according to the at least one application identifier; detecting a second operation; when the second operation satisfies a second preset condition, obtaining a corresponding application management command according to the second operation; and sending the application management command to the second device, so that the second device manages the first application according to the application management command.
摘要:
Increasing longevity of the nitrogen content of soil through improved liquid delivery formulations of urease inhibitors and/or nitrification inhibitors designed to apply to fertilizers, especially urea and manure based fertilizers These delivery formulations provide an environmentally sound and inherently safe solvating system that improves the storage stability of the urease inhibitors by utilizing aprotic solvents, maintain the urease inhibitors and/or nitrification inhibitors in solution to storage temperatures of at least 10° C. and provides improved application to fertilizer of urease and/or nitrification inhibitors. These delivery formulations enable safe storage, transport and subsequent application or blending with urea based or manure based fertilizers that can be applied to soil in either a liquid or granular form to provide improved nitrogen retention in the soil for uptake for plant life.
