Abstract: A muffler for the air exhaust of pneumatic tools to reduce the noise level thereof. Composition of the muffler comprises an abrasive grit distributed on a thin flexible base to which it is secured. An example of the composition is represented by commercially available grades of common emery cloth. Positioning the muffler in a manner affording retention of its flexibility enables sound muffling within an otherwise restrictive exhaust passage with only minimal, if any, adverse effect on operational characteristics of the tool. With this construction it is possible to muffle the exhaust of tools previously regarded as impossible or impractical to muffle satisfactorily because of space limitations ordinarily insufficient to accommodate a muffler device.

Abstract: An encapsulated, self-contained gauge transducer to provide output information from a variable pressure source to a variety of output devices such as an indicating gauge. A housing contains a Bourdon tube sealed at both ends and surrounded by a fluid fill of incompressible liquid. Pressure variations from a source are communicated via a diaphragm in the housing wall through the liquid fill to be exerted externally against the Bourdon tube. A magnet is operably connected to the free end of the Bourdon tube for rotational displacement therewith in response to tube deflections imposed by pressure change.

Abstract: A lower mandrel threadedly connected to a subsurface pump barrel at its lower end is threadedly connected to an upper mandrel and through which a rod assembly adapted to reciprocate a pump piston through such barrel is adapted to be lowered from the earth''s surface by the rod assembly to a restricted diameter tubing seal located within a tubing string in an earth borehole. A collected tubular member adapted to rotate about the lower mandrel is caused to deflect inwardly in passing through the tubing seal ring and further movement of the apparatus through the seal ring causes it to be locked in place within the tubing string. The single split collet entails a lower split shoulder which can deflect through the sealing ring with a second upper shoulder tapered to fit the taper on the top of the seal ring after passing through the ring, the lower shoulder of the collet being allowed to expand out to lock against the bottom of the sealing ring and hold the upper shoulder of the collet locked against the upper shoulder of the ring to thereby obtain a fluid seal between them.

Abstract: Adjacent discrete plunger sections having alternate right and left hand spiral threads are loosely fitted on a cylindrical mandrel, one end of which has a threaded valve cage with a ball and seat therein, a shoulder section being threadedly engaged with the other end of the mandrel. The plunger sections are compressed by further increasing rotational pressure to the threaded shoulder section. Plunger sections are essentially nylon (polyamide) having a fiber glass filler material. Because of the creep of the material, end compression is applied in an amount which causes a squeeze of approximately 1/32 inch per foot of plunger section to purposely induce creep in the manufacturing process. After approximately 24 hours, during which the material creeps about 75 percent of its one year creep, the plunger assembly is centerless ground to the desired outside diameter. In addition to the discrete plunger sections being alternately right and left hand threaded, each section has its end portion unthreaded. The unthreaded end portion provides for pressure change and also a space for sand to fall out. The use of the unthreaded section and the alternately changing thread directions causes flow reversals and turbulent flow conditions which reduce slippage rate and increases the efficiency of the pump. The alternate right and left hand portions reduce the torque in the system and also reduce the flow rate through the spiral by causing direction changes.

Abstract: A slotted, continuous elastomeric sheath is applied to a wireline as the wireline and its instruments connected thereto are lowered into a plastic lined tubing within an earth borehole, the elastomeric sheath being used to prevent damage to the plastic coating on the interior of the tubing. The tubular elastomeric sheath is wound on a storage drum for transportation and the application of the sheath to the wireline. The sheath passes through a measuring sheave having a throat positioned at the wireline to be covered. As the sheath approaches the wireline, an orienting finger is used within the slot in the sheath causing the slot to open up. The opening also results from a natural consequence of the sheath being bent about a radius with the slot in the sheath oriented to the outside of the sheave throat. Idler rollers are provided to facilitate the alignment of the sheath with the wireline. The measuring sheave is also used to monitor the linear velocity of the sheath as it is being removed from the wireline. The linear velocity of the wireline is also monitored and compared with the velocity of the sheath. An electrical comparator circuit drives a variable speed motor to either increase or decrease the velocity of the sheath to provide a means for removing the sheath from the wireline at the same velocity as the wireline as it is being hoisted from the well bore. During the application of the sheath to the wireline, the drum upon which the sheath is wound is allowed to rotate freely without the use of the motor and the sheath pulled off the drum by the frictional forces between the sheath and the wireline.

Abstract: This specification discloses a system for obtaining a water production profile of a producing oil well. A logging instrument is used having a deuterium tritium neutron source. A detector is mounted in the tool above the neutron source and an inflatable bag is positioned between the source and this detector. A positive displacement pump, servo-controlled from the surface, is provided to permit precisely determined amounts of liquid to be pumped into the bag from the borehole to thus vary the transit time of the borehole fluid from the source to the detector by a known amount. A second detector is positioned below the neutron source to detect whether any downward circulation in the borehole takes place. In an alternative embodiment, a pair of detectors are positioned on the same side of the source within the borehole instrument.

Abstract: A regulator to limit the raising, pulling, or stretching load capacity of a lever type hoist to a predetermined maximum. The regulator is operably mounted between the drive input applied via an operating lever and the output drive on which a load is received and/or contained. An adjustably presettable braking friction applied between coaxially interfit components rotationally connects the input and output drives. In the event the input driving force exceeds the imposed braking friction, the hoist is rendered inoperable to raise, pull or stretch the load but continues operable to lower or release the load.
