Abstract: A mandrel in production tubing within a well has a side pocket with an inlet port for connection to an upper control line segment that extends upward alongside the production tubing. An outlet port is below the inlet port for connection to a lower control line segment extending below the pocket. A filter assembly is lowered through the production tubing into the pocket. A valve at a lower end of the pocket is movable from a closed position closing the outlet port to an open position opening the outlet port. A probe mounted to a lower end of the filter assembly engages and pushes the valve from the closed position to the open position while the filter assembly is being seated in the pocket.

Abstract: A method for monitoring an engagement process of an engaging pinion of a starter motor for a vehicle drive, in which an armature of the starter motor is moved, includes detecting a magnetic coil signal while current is applied to the magnetic coil of the magnet, in order to obtain a signal profile, particularly a current profile; generating a frequency profile by transforming the signal profile using a time-frequency transform; comparing the frequency profile to at least one reference frequency profile; and monitoring the engagement process based on the comparison.

Abstract: A printed circuit board including a substrate of electrically insulating material and a pattern of electrically conducting paths formed on at least one side of the substrate. One or more electronic components mounted to the substrate in connection with the electrically conductive paths. At least one of the components including a base solder connection between a base surface and a facing conducting surface of the component. The base solder connection is substantially obscured from view from the side of the substrate to which the component is attached and an opening is provided extending through the substrate beneath the base surface of the component so that the base solder connection is visible through the opening.

Abstract: A method for monitoring a meshing process of a meshing pinion of a starter motor for a vehicle drive, in which an armature of the starter motor is moved by a magnet, has the following steps: detecting a solenoid signal when a solenoid of the magnet is energized in order to obtain a signal profile, in particular a current profile; generating a differential profile by differentiating the signal profile; determining zero crossings in the differential profile; and monitoring the meshing process on the basis of the determined zero crossings.

Abstract: An electrical submersible pump assembly has modules including a pump, a motor, and a seal section. A drive shaft assembly extends from the motor through each of the modules. A threaded connection between at least two of the modules includes a first adapter having external threads and a second adapter having a neck with an external load shoulder. A collar is rotatably carried and axially movable on the neck. The collar has internal threads and an internal load shoulder. A shoulder ring having two segments encircles the neck. The shoulder ring has a first surface in abutment with the external load shoulder and a second surface in abutment with the internal load shoulder. A resilient ring tits around an outer diameter of the shoulder ring for retaining the ring segments on the neck prior to the collar being in threaded engagement with the threads of the first adapter.
