Abstract: An oil well assembly and a method thereof for injecting fluid into an oil reservoir to promote production of oil from the oil reservoir is provided. The oil well assembly comprises a pump for pumping oil from the oil reservoir to the surface and for transporting treatment fluid from the surface to a valve for controlling flow of treatment fluid to the oil reservoir. The pump may be lubricated using the treatment fluid even when the valve has closed the flow of treatment fluid.

Abstract: A method is provided for limiting access to airspace by drones. The method includes receiving position information from a user associated with a property identified by the position information. The method also includes assembling the position information with other position information to compile a comprehensive configurable flight zone database. The method further includes pushing the configurable flight zone database to at least one drone. The drone accesses the configurable flight zone database to determine if movement is allowed, and the drone is programmed to not fly into areas identified in the configurable flight zone database. In the method, the drone may be further programmed to prohibit directing a camera into the areas identified in the configurable flight zone database.

Abstract: A torque converter for transferring torque from an input shaft to an output shaft, having a turbine wheel, an impeller connected to the input shaft to drive the turbine wheel hydrodynamically, a centrifugal force pendulum connected to the turbine wheel to damp torsional vibrations, a first torsion damper to drive the output shaft by means of the turbine wheel, and a converter clutch and a second torsion damper for selective torsionally damped coupling of the input shaft with the turbine wheel. One of the torsion dampers in this case includes two torsion damper elements, which are arranged in series with each other.

Abstract: A secure one-time use capsule based personalized and encrypted on-demand communication platform enables encrypted personalized secure on-demand stateless single-use capsuled communication channels over the Internet. Using the personalized capsuled secure communication system, a greater degree of communication security can be achieved than in the existing conventional methods.

Abstract: The current invention consists of a fan forced heat sink oil cooler which attaches to the end of an oil filter. Typically, the invention will be used for the cooling of engine oil on an air cooled motorcycle. The current invention utilizes a housing attached to a fan forced, finned heat sink to remove heat from the engine oil expelling engine heat to the ambient air. The invention externally clamps on the oil filter which effectively turns the oil filter into an oil cooler. The design provides engine oil cooling during periods of idle or slow speeds as well as while the vehicle is in motion. The new design has remedied the necessity of penetrating and changing the existing oil route thus avoiding harm to the engine due to malfunction of an oil cooler. Another advantage to this design is simple and quick installation with ordinary knowledge and skill.
