摘要:
A battery charging mechanism which is driven by a coil spring. A gear train driven by the spring includes a wheel having peripheral teeth. A control lever is reciprocated pivotally by a small spring to engage the teeth of the wheel in a manner to control its rotation. The wheel in turn applies impulses which help to keep the lever in motion. Links connected with the lever turn gears which drive alternators in order to deliver charging current to the battery. An electric motor acts to automatically wind up the drive spring when it has uncoiled below a preselected tension level.

A system includes a drill bit, and a tubular connected thereto. The tubular is configured to be rotated to rotate the drill bit and drill a length of a borehole and cemented in place. The tubular and the drill bit form a conduit to permit cement to be pumped through the tubular and the drill bit and into an annulus. The system also includes a collar disposed between the tubular and the drill bit. The collar includes a receptacle made from a drillable material, which has a profile that corresponds to a shape of a component deployed through the length of the tubular, and is configured to form a substantially fluid tight seal between the component and the drillable material when the component is seated in the receptacle. The collar and the component prevent backflow of the cement.
摘要:
A fluid loss control valve and packer assembly including a fluid loss control valve, a packer disposed adjacent the fluid loss control valve, a hydraulic opening module operably connected to the valve, and a port associated with the hydraulic opening module and positioned to be exposed to annulus pressure during use. A method for operating a fluid loss control valve in an assembly.

An indicating tool includes a mandrel including a support, an indicator housing surrounding the mandrel, and a member movable radially with respect to the housing. The mandrel is movable longitudinally with respect to the indicator housing, and the indicator housing is at least substantially rotationally locked with respect to the mandrel. The member is engageable with an inner profile of an outer tubular in which the indicating tool is employed, and the member has a substantially helical side. The member is movable radially inward towards the mandrel when the support is longitudinally displaced from the member, and the member is blocked from movement radially inwards when the support is longitudinally aligned with the member.

Embodiments of the invention provide an apparatus, method, and program product to control a lamp system. The apparatus comprises a plasma lamp bulb (20) and a microwave generator (12) operable to generate a microwave energy field to excite the plasma lamp bulb (20) to emit ultraviolet light (24). The apparatus further comprises a sensor (70) to measure the intensity of the ultraviolet light (24) and a reflector (42) positioned between the plasma lamp bulb (20) and the sensor (70) The reflector (42) is operable to reflect at least a portion of the ultraviolet light (24) generated by the plasma lamp bulb (20). The method comprises receiving a target intensity for the ultraviolet light (24) and measuring an intensity of the ultraviolet light (24) using a sensor (70). The method further comprises comparing the target intensity to the measured intensity and, in response to the comparison, adjusting power to a microwave generator (12) to adjust the intensity of the ultraviolet light (24).
摘要:
Apparatus for generating ultraviolet light and methods of operating an ultraviolet light source. The apparatus may include a microwave chamber (16) enclosing an interior space, a light source (10) with a lamp head (28) coupled to the microwave chamber (16), an ultraviolet (UV) transmissive member (88) positioned above the lamp face (32) and below the interior space to define a plenum (116) therebetween, and an exhaust system (100) coupled in fluid communication with the plenum. The lamp head (28) has a lamp face (32) through which ultraviolet light (34) and cooling air (30) are emitted. The UV transmissive member (88) is configured to transmit the ultraviolet light (34) into the interior space and to divert the cooling air (30) from the interior space. The exhaust system (100) configured to exhaust the cooling air (30) from the plenum (116).
摘要:
A microwave excited ultraviolet lamp system with a data logging and retrieval circuit and method for operating the same. The data logging and retrieval circuit stores operational data in a cache memory using a FIFO data storage protocol. The contents of the cache memory are periodically copied to a larger removable memory so that the removable memory contains a relatively long historical record of the system operational parameters. The data logging and retrieval circuit includes a data port configured to load the contents of the cache memory into an external device when the device is coupled to the data port. A second data port allows the external device to supply power to the data logging and retrieval circuit so that data may be retrieved when the internal power supply is malfunctioning. Data stored in the removable memory may be protected so that it may only be accessed by authorized personnel.
