Abstract: Fluid delivery devices for delivering therapeutic agents are described. More particularly, this disclosure relates to drug reconstitution devices having a plurality of components movable with respect to one another such that an active agent and a solvent can be reconstituted within the device prior to injection. The fluid delivery devices can include a housing, a cartridge holder, a cartridge disposed within the cartridge holder, a button rod, and a foot. The cartridge stores the active agent and the solvent, which are separated by one or more stoppers. The button rod and foot can provide an axial force upon the stopper(s) in the cartridge to inject the fluid once reconstituted. The foot and the button rod can be separate components, thereby enabling the foot to rotate independently with respect to the button rod as the cartridge holder is rotated to reconstitute the therapeutic and prime the device for injection.

Abstract: The subject matter disclosed herein relates to methods, systems and apparatuses for segmental duct couplers for use during and after formation of concrete segments. Segmental duct coupling systems can include a number of components for coupling ducts both during and after formation of the concrete segments. In one aspect, the coupling system can include a locking member and forming member disposed between coupling ends of segmental ducts. In another aspect, a coupling system can include a deformable member disposed between coupling ends of ducts cast within pre-cast and match-cast concrete segments.

Abstract: An apparatus for analyzing particulates including solutes in a sample liquid suspension in which the sample liquid suspension flows through an aperture into a first region of a reservoir containing particle free liquid to form a jet which entrains particle free liquid to ensheathe the jet. The jet passes through a muffler which includes a funnel and a throat into a second region of said reservoir where the particle free liquid and particulates are mixed. The throat is configured to prevent regurgitation of liquid from the second region back into the first region. A return passage connects the second region of the reservoir to the first region. The energy of the jet stream causes liquid to flow from the second region to the first region to provide particle free liquid to the first region. The return passage is configured or contains means to continuously mix the advancing liquid to prevent central streamers and the peripheral Coanda effect.

Abstract: This invention encompasses a heat stabilized composition of aspartame, its salts or metal complexes and a partially hydrogenated vegetable oil melting at about 120.degree. F. or above. This composition is particularly useful in baking applications for aspartame.

Abstract: A composition and method for heat stabilizing dipeptide sweeteners for baking and cooking is described using a polyglucose or a polymaltose.

Abstract: This invention relates to a method of increasing the dispersibility and mixability of psyllium hydrophilic mucilloid by applying a film of hydrolyzed starch oligosaccharide, a mono-or di-saccharide, a polyglucose, or a polymaltose.
