摘要： A water-base wellbore fluid for use in subterranean wells that penetrate through a subterranean formation containing a shale which swells in the presence of water. The well bore fluid includes, an aqueous based continuous phase, and a shale hydration inhibition agent. One illustrative shale hydration inhibition agent is preferably the reaction product of a hydrogenation reaction of the product of the reaction of an aromatic amine with an aldehyde, preferably formaldehyde. Alternatively the shale hydration inhibition agent may be the reaction product of a hydrogenation reaction of the product of the reaction of aniline and formaldehyde. In one illustrative embodiment, the shale hydration inhibition agent is selected from the class of compounds known as polycycloaliphatic amines. The shale hydration inhibition agent may be present in the form of a free-base or preferably in the form of an acid salt of the disclosed amine compounds. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the fluid.

摘要： An electrical connector includes a dielectric housing having a terminal-receiving passage for insertion thereinto of a terminal. The terminal includes a cantilevered spring contact arm projecting into the passage for engagement by an appropriate conductor inserted into the passage. The terminal further includes an engagement arm projecting into the passage behind the cantilevered spring contact arm at a location to perform the dual function of providing an anti-overstress engagement surface for the spring contact arm and providing an engagement shoulder for an insertion tool which forces the terminal into the terminal-receiving passage of the housing. The passage is open-ended to allow the conductor to be inserted completely through the housing past the contact arm of the terminal and into the clearance hole of the printed circuit board.

摘要： An electrical terminal pin is provided with a pin tip for insertion into a mating electrical female terminal, a hole in a printed circuit board or the like. The pin has an electrically conductive core plated with an electrically conductive layer. The pin tip is formed of a generally rounded pyramidal configuration defining four slightly curved convex sides joined at four edges converging at a pin end. Two opposite sides of the pin tip are non-plated. The other two opposite sides of the pin tip are plated with the conductive layer. Portions of the conductive plating layer overlap the edges of the pin tip in a smooth or rounded configuration to eliminate any sharpness thereof and to provide additional plated areas over the exposed core material. The pin tip is formed by a cutting and coining operation to form the configuration of the tip and to coin the overlapping portions of the conductive plating layer over the sharp edges of the pin tip.

摘要： Invert emulsion compositions including an oleaginous, a non-oleaginous and an amine surfactant that are useful in the oil and gas well drilling art are disclosed. The amine surfactant is selected so that the invert emulsion can be converted form a water-in-oil type emulsion to a oil-in-water type emulsion upon the protonation of the amine surfactant. Deprotonation of the amine surfactant reverses the conversion. This solution also permits the conversion of oil-wet solids in the fluid into water-wet solids.

Each metal layer includes a joining section, a contact section and a terminating section. A plurality of projections on the joining sections of the layers are interengaged within a respective plurality of recesses in adjacent layers to align the layers and provide a strong mechanical and good electrical joint between the layers. Solder tails extend linearly along the bottom edge of each joining section to form a plurality of rows of solder tails, and the terminating portions of the metal layers are bent outwardly to separate the rows of solder tails from each other. The contact section of one metal layer may include a generally planar finger which is coplanar with a planar finger of another of the metal layers.

摘要： An electrical power connector is mountable on a printed circuit board. The connector includes an outer terminal and an inner terminal, both of which are of generally inverted U-shaped configurations, with the inner terminal nested in the outer terminal. Solder tails project downwardly from bottom edges of side walls of the two terminals. Both terminals have a pair of blade portions projecting forwardly from the respective side walls of the terminals, whereby the blade portions of each terminal are spaced from each other. The blade portions of one terminal are generally coplanar with the blade portions of the other terminal. A dielectric housing is overmolded about the side walls of the outer terminal, leaving the solder tails and the outside surfaces of the blade portions exposed. The housing has a projecting portion extending into the spacing between the blade portions of the two terminals against the inside surfaces of the blade portions, leaving the outside surfaces of the blade portions exposed.

摘要： A water-base fluid for use in drilling wells and other drilling operation includes a shale clay which swells in the presence of water. The fluid preferably includes: an aqueous based continuous phase, and a shale hydration inhibition agent having the formula: H—(OR)x—[—NH—CH2—CH2—CH2—O—CH2—CH2—NH—]—(R′O)y—H wherein R and R′ are independently selectable alkylene groups having 2 to 4 carbon atoms, and wherein x and y have independently selected values such that the sum of x and y is at least 1. The shale hydration inhibition agent should be present in sufficient concentration to reduce the swelling of the shale clay. The fluid may be used for formulating drilling fluids such as water-base drilling muds or clear brine drilling fluids. The fluid may also be used in the slurrification and disposal of drill cuttings that contain water swellable clays or shale clays.
