Abstract: A method of making a high-temperature and fire-resistant fabric is described in which staple carbon fiber yarns are woven into a unified multi-layer woven fabric. The warp ends and filling picks of the unified multi-layer woven structure are positioned such that they prevent penetration of fire flames, welding sparks and molten metal spatter from penetrating through the unified multi-layer fabric.

Abstract: A water-base fluid for use in drilling, cementing, workover, fracturing and abandonment of subterranean wells through a formation containing shale which swells in the presence of water. In one illustrative embodiment, the drilling fluid is composed of an aqueous based continuous phase, a weighting agent, and a shale hydration inhibition agent. The shale hydration inhibition agent should have the general formula: in which R and R′ independently selected from hydrogen, methyl, ethyl or propyl, and X has a value from 1 to 6. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the drilling fluid. The drilling fluid may be formulated to include a wide variety of components of aqueous based drilling fluids, such as weighting agents, fluid loss control agents, suspending agents, viscosifying agents, rheology control agents, as well as other compounds and materials known to one of skill in the art. The fluids may also be used in fracturing and the disposal by reinjection of drilling cutting into a selected subterranean disposal formation.

In one illustrative embodiment, the drilling fluid includes, an aqueous based continuous phase, a weighting agent, and a shale hydration inhibition agent. The shale hydration inhibition agent should have the general formula: in which A is independently selected from H and CH2CH2CH2NH2; and in which B is independently selected from H, CH2CH2OH, CH2CH2OCH2CH2CH2NH2 and CH2CH2CH2NH2. The shale hydration inhibition agent is present in sufficient concentration to substantially reduce the swelling of shale drilling cuttings upon contact with the drilling fluid. The drilling fluid may be formulated to include a wide variety of components of aqueous based drilling fluids, such as weighting agents, fluid loss control agents, suspending agents, viscosifying agents, rheology control agents, as well as other compounds and materials known to one of skill in the art. The fluids may also be used in the disposal by reinjection of drilling cutting into a selected subterranean disposal formation.

Abstract: A method of manufacturing electrical terminals and/or a terminal module is disclosed. The method includes the steps of stamping from a sheet of metal material a blank for a plurality of elongated terminals having contact portions at one end and terminal portions at the other end and joining the terminals by a tie bar intermediate the ends. The contact portions of the respective terminals are separated from each other by the stamping step. The terminal portions remain joined in the sheet of metal after the stamping step. The blank then is sheared to separate the terminal portions. The tie bar is cut to separate the terminals. In order to form a terminal module, a dielectric housing is overmolded about the terminals intermediate the ends thereof, with the tie bar being located outside the housing and removed after the overmolding process.
