Abstract: An apparatus for washing undesirable matter off of the exterior of tubular conduits forming a conduit string during trip out of the conduit string within a subterranean well. The tubular conduits may be drill or workover pipe, or the like. A cylindrical housing has first and second opposite ends. A removable elastomeric seal means is provided across each of the first and second ends. The seal means is selectively secured relative to the housing. Each seal means defines an open passageway therethrough and which is centrally positioned there across. The open passageway through each seal means is sized for introduction, of the tubular conduits into and out of the cylindrical housing and the seal means. A circumferentially extending lip area of each seal means faces toward the respective passageways for snug, wiping contact around the exterior of the tubular conduits during movements of the conduit string into and out of the cylindrical housing.

Abstract: A secondary plugging tool is disclosed for use in a subterranean plug, such as in a plugged and/or abandoned well. The repaired plug may be of a cementicious material, or a mechanically, hydraulically or electrically set plug or packer. The plugging tool includes an outer housing containing an eutectic metal alloy. A thermitic reaction charge is contained within chambers within an inner tubular member and a lower housing. The lower end of the outer housing being ported circumferentially there around, the thermitic reaction charge activates the eutectic metal charge such that the eutectic charge melts and pours out of the outer housing and across and upon the initial plug to repair any failure areas therein.

Abstract: A well tool and method for heating and depositing first and second charges of selective temperature melting metal alloys for repairing failure spots along a section of a tubular conduit, such as casing, in a subterranean well. A fuel charge is provided and is ignited to first melt the lower temperature melting metal alloy charge and thereafter the higher temperature metal alloy charge, such that a metal precipitate is formed from the heated higher temperature melting metal alloy charge. The housing defines a sacrificial wall which is opened or cleared as the higher temperature metal alloy charge melts, thus enabling the precipitate of the higher temperature melting alloy charge to be discharged from the housing to form a bridge for subsequent movements thereacross of the lower temperature melting alloy charge, into the well immediate the area of the failure spots.

Abstract: A wild animal feeder is disclosed which is attachedly suspended form a tree or other stabilized element and may be horizontally and vertically suspended from same.

Abstract: Method and apparatus are disclosed for confirming the integrity of a seal system extending between a conduit disposed within a subterranean well and a surface or top Christmas tree assembly such that the confirmation steps do not adversely thereafter effect the sealing integrity of the system when exposed to high pressure and/or temperature environments.

Abstract: A mechanical latching device is provided for threaded connections, such as those found in a medical syringe. The connections each have a thread profile with crest and root elements. At least one flexible finger or projection extends outwardly from within one of the root portions and an outwardly extending ridge is provided on the second threaded member extending from the ridge. Interference with normal threading movements between connection elements is abated, while resistance is provided to unthreading manipulations of the connections.

Abstract: A pressure balanced, slow actuating device and method for manipulation of an auxiliary tool within a subterranean well in which the hydrostatic pressure within well fluids in the well are utilized to meter and extend the timing of actuation of a component or auxiliary tool within a subterranean well.

Abstract: An outlet assembly is provided for securement into a receiving profile defined upon the bottom surface of a sink for laboratory or like usage. A sleeve is contoured such that an upper lip provides a sloping surface toward the interior of the sleeve with the lip being contoured slopingly toward the interior of the sleeve for further gravitational urging of liquid into the interior of the sleeve. The lower surface of the lip is contoured to receive a lock-nut which includes a grooveway configuration to enhance the securement of a locking-nut relative to the sink or a gasket disposed between the lock-nut and the lower face of the sink. The sleeve may include a contoured receiving profile for a filtering disk which is selectively placeable within the sleeve and which includes a series of fluid flow passageways.

Abstract: The present invention is directed to an apparatus and method for providing absorption of two fluid phases with one another and for the magnetic treatment of the phases for molecular realignment for effective separation of contaminants.

Abstract: A liquid drain apparatus for incorporation within a counter top intended for use within tops for laboratories and hospitals, or the like. The drain profile provides a series of ribs and valleys within a base horizontally angled from a higher outboard end to a deeper inboard end so that liquid drainage will collect through the drain profile and be directed toward a draining receptacle included or placeable in the drain profile. The draining receptacle, which may be used independent of the drain profile, includes a cylindrical body and a basket having a series of ports and slots to permit maximum drainage flow as the basket fills with entrapped solids.

Abstract: A thru-tubing gravel packing operation utilizing inflatable packing elements and a flow cross-over assembly which selectively opens flow ports for effecting steps in the gravel packing operation and which further provides concentric flow paths through the cross-over assembly for transmitting fluid pressure to valving means and the interior of the packing element or elements to move them to set and sealed condition, whereby the outer diameter of the inflatable element in the sealed condition may preferably expand to at least twice the outer diameter of such element in the initial or run-in condition, for the sequential setting thereof while also transmitting a variation in the pressured fluid to actuate a valve for circulation of the gravel packing fluid exterior of the assembly and for permitting return of fluids through the assembly without the gravel.

Abstract: A non-reusable retractable safety syringe is provided which has a hollow plunger and a seal member carried thereon. The provision of the plunger and the seal relative to the barrel permits the plunger, with sufficient strength, to carry applied pressure through the device during injection of a medicinal or other fluid into a patient, and yet permit the seal disposed at one end of the plunger to have maximum sealing integrity between the plunger and a cylindrical barrel disposed around the exterior of the plunger, to abate leakage of the liquid in a chamber within the barrel, as the plunger is manipulated from an expanded position to an expended position and thereafter to a third, or collapsed position. Designs for securing the seal relative to the plunger are disclosed. The syringe may be used to insert and/or withdraw fluid relative to the patient.

Abstract: Timing of movements of a spring between a stressed and a free state is delayed by dampening the spring movement through incorporation of a component having a restricted access diameter whereby frictional contact of the spring through the component will prolong the time required to move the spring between states to enhance control of the spring actuation.
