A differential pressure operated gas lift includes a valve element movable in a tubular body to open and close a gas flow passage having flow restricting orifices upstream thereof. A coil spring tends to open the valve element. In the open position of the valve element an external pressure responsive surface engages a seat which is axially adjustable to vary the spring force and change the length of travel of the valve element between its open and closed positions. The reopening differential pressure can be changed while maintaining the same closing pressure differential. Very large injection rates can be implemented at low differential pressures.

There is disclosed herein a machine for performing nucleic acid amplification under computer control. The machine utilizes any one of a number of heating and cooling systems under control of a host computer which directs the heating and cooling systems to heat and cool a reaction-chamber-containing heat exchanger at appropriate times in the process. The reaction chambers are pre-loaded with the nucleic acid(s) to be amplified, a thermostable enzyme to catalyze polymerization, specific oligonucleotide primers, and four different nucleotide triphosphates. Also disclosed is the process for the amplification chain reaction implemented by the machine, which utilizes a thermostable enzyme.

A display includes a riser and a cap where articles, such as jewelry elements and their holders, can be placed. The riser has a riser base and a riser side and the cap includes a cap side and a cap platform, wherein the cap side is in at least one of sliding and removable engagement with the riser side. In an alternative embodiment, the riser has a riser guide coupled with the riser side or the riser base, and the display further includes a drawer. The drawer has a drawer top, a drawer side, a drawer side guide coupled with the drawer side, and a drawer top guide. The cap has a cap platform and, at least one of a groove in the cap platform and a cap platform wide coupled with the cap platform. The groove and/or the cap platform guide is in at least one of sliding and removable engagement with the drawer top guide. In yet another embodiment, the display further includes removable light fixtures having light emitting diodes.

An endoscopic forceps includes a housing having a shaft attached thereto that supports a pair of jaws disposed at a distal end thereof. A drive assembly having a drive shaft with a proximal end is operable to move the jaws relative to one another from an open to closed positions. A knife assembly is operable to advance a knife through tissue disposed between the jaws and includes a flange disposed thereon. A knife lockout is included that has a flange configured to engage the proximal end of the drive shaft and a lockout arm configured to engage the flange of the knife assembly to prevent movement thereof. Movement of the jaws to the closed position causes the proximal end of the drive shaft to engage the flange on the lockout which causes the lockout arm to disengage the flange on the knife assembly to permit advancement of the knife.

Aspects of the disclosure are implemented using a variety of systems and methods involving pill-filtering article that is located and secured inside a pill container. Using one such system, an assembly of articles distributes one pill at a time in the form of a single-pill dispensing apparatus that includes a pill-storage container and such a pill-filtering article. The pill-storage container has an inner wall, an upper portion with a rim region at which a cap may be secured to the pill-storage container, and a lower portion configured for containing pills. The pill-filtering article is configured with a size and a shape that facilitates securing the article inside the pill-storage container near the inner wall, above the lower portion, and below the upper rim region, and also configured with a plurality of channel-defining regions including a first channel-defining region through which one-pill at a time passes and including a second channel-defining region through which one pill at a time passes. Each of the plurality of channel-defining regions region is respectively configured and arranged to facilitate a modification that results in formation of an aperture near a boundary of the channel-defining region for passing one pill at a time, and to pass pills that are of different types in terms of at least one of size and shape. In this regard, when only one of the plurality of channel-defining regions is modified, the pill-filtering article permits only one pill at a time to pass, through the aperture ensuing from the modification, from the lower portion of the container to the upper portion of the container.
