A pop-up drain assembly for a sink has drain piping, a stopper in the drain piping, a pivot rod for opening and closing the stopper and tends not to clog because the pivot rod is not within a fluid flow path. In one embodiment the stopper has flow diverter plates that channel fluid flowing through the drain piping away from the pivot rod so that hair, waste and debris does not catch on and accumulate on the pivot rod. In another embodiment the stopper and the pivot rod are engaged through magnetic coupling, and the pivot rod does not protrude into the fluid flow path. The stopper is preferably variable in length for adjustment to fit different distances from the pivot rod to the top of the drain piping.

A male connector includes a body and an elastomeric member. The body has a proximal end and a distal end. The elastomeric member is disposed around an outer surface of the distal end of the body. The distal end of the body is configured to be received into a female connector interface in a device. The proximal end of the body is configured to couple with an electronic block connector selected from a plurality of electronic block connectors, each of which has a different pin arrangement but a common coupling interface.

A micro solder pot includes a dielectric substrate having at least one hole formed therein, a conductive coating coupled to the interior of the hole, and at least one heat transfer pad spaced from the hole in thermal communication with the conductive coating of the hole. When the heat transfer pad is exposed to a heat source, the conductive coating inside the hole is heated. The micro solder pot may also include a thermally activated conductive material disposed within the hole. When the heat transfer pad is exposed to a heat source, the thermally activated conductive material becomes liquidus such that a component can be inserted into the liquidus material. When the heat source is removed, the thermally activated conductive material cools to couple the component to the conductive coating in the hole.

A mini wave solder system includes a dielectric substrate having a hole defined therethrough, a conductive heat transfer pad, and a conductive retention pad. A conductive material is associated with the hole. The heat transfer pad and retention pad are disposed adjacent to the hole and the retention pad has a thermally activated conductive material positioned thereon. The heat transfer pad, retention pad, and hole are in thermal communication with each other. A method for coupling a component to a substrate utilizing this system is also described. A wire termination system includes a dielectric substrate having a surface, a conductive material disposed on the surface of the dielectric substrate comprising a retention pad and a heat transfer pad in thermal communication with each other, and a thermally activated conductive material positioned on the retention pad. When heat is applied to the heat transfer pad, thermal energy travels to the retention pad to melt the thermally activated conductive material in order to secure a component to the conductive material. A method for coupling a component to a dielectric substrate in a wire termination system is also described. A pin connection system for coupling a pin to a dielectric substrate is also described. The pin connection system includes a dielectric substrate having a hole and electrical traces defined on a surface of the substrate, a pin positioned in the hole, and a connection solder disposed on a top surface of the pin. The pin has at least one radial protrusion disposed on an outer periphery thereof for perpendicularly aligning the pin with the substrate and for retaining the pin in the substrate in a substantially immobile manner. The connection solder at least one of strengthens the mechanical connection of the pin to the substrate and electrically connects the pin to the traces on the substrate.

A mechanical limiter switch for use in a medical or surgical device has a substantially cylindrically shaped housing with a perimeter and an opening in an axial direction. The housing has a pattern along the perimeter. A spring is mounted in the opening along the axial direction, and is pre-stressed for movement in a radial direction and pre-stressed for movement in the axial direction. The spring has a radial member protruding through the pattern of the housing. A plunger is mounted in the opening along the axial direction, abutting the spring for urging the spring in the axial direction and for moving the member in the pattern along the perimeter. After a pre-determined number of activations of the plunger in the axial direction, the member will come to a terminating position and will either contact a pin to establish electrical continuity or at the terminating position break electrical continuity.

A system of downhole communication and control is provided in methods and associated apparatus for data retrieval, monitoring and tool actuation. In a described embodiment, an item of equipment installed in a tubular string has a first communication device associated therewith. A tool conveyed into the tubular string has a second communication device therein. Communication is established between the first and second devices. Such communication may be utilized to control operation of the tool, retrieve status information regarding the item of equipment, supply power to the first device and/or identify the item of equipment to the tool.
摘要:
Apparatus and method for testing a well and obtaining a fluid sample therefrom. The apparatus comprises a housing connectable to a tubing string and having a packer at the lower end thereof. The packer is set, and fluid is flowed from a formation or zone of interest into the chamber and then into a sampler in a controlled manner such that the fluid in the housing or sampler does not flash. In one embodiment, a pump is used to flow formation fluid; plugs are used in the housing to first flow dirty fluid and then flow clean fluid into the housing. In another embodiment, a nitrogen cushion is bled slowly to flow fluid into the housing.
