Title: Arrayed-wave guide grating multi/demultiplexer with loop-back optical paths
Inventor: TACHIKAWA YOSHIAKI
IPC: H01S5/026
Filed: 1993-09-28
Granted: 1998-12-29
Abstract: An optical device is presented which is useful for optical signal transmission and switching systems by multiplexing and demultiplexing optical signals in looped optical paths, consisting of a plurality of individual loop-back optical paths. The device is essentially a multi/demultiplexer having an arrayed waveguide grating disposed between a plurality of input sections and output sections which are joined by the plurality of individual loop-back optical paths.  Because the modulated signals are looped back into the same optical paths using the same devices, problems of mismatching performance introduced by using different optical devices are avoided.  The device processes individual optical signals of different wavelengths, minimizes splitting losses, and reduces noise components by producing narrow bandpass signals of high signal to noise ratio. Optical signal splitting and insertion, delay line memory and delay equalization circuits can all be handled by the same circuit configuration.  The device is simple in construction, reliable in performance and economical in production.

Granted: 2005-08-16
Abstract: The invention concerns a plastic screwable closure cap which possesses a bung type internal seal for sealing a closeable container. The internal seal comprises a narrow sealing portion with an insert portion immediately beneath, said insert portion serving to centre and gently introduce the internal seal. In order to attain the earliest possible venting of the closure cap when screwing off, venting recesses are provided on the insert zone. These prevent the insert portion from sealing the container, and enable the release of gas from the container as soon as the sealing portion comes out of engagement with the container mouth.      The side surfaces of the vent recesses also serves as friction surfaces, in order to generally flatten irregularities on the container mount before the actual sealing portion is engaged.

Title: Oxidant injection for improved controlled oxidation
Inventor: VUONG DINH-CUONG
IPC: F23J1/00
Filed: 1995-06-28
Granted: 2006-11-28
Abstract: A selective deslagging operation is conducted in a partial oxidation reactor wherein a first predetermined portion of the reactor is selectively deslagged by derivatization while limiting derivatizing slag conditions in a second predetermined portion of the reactor. Selective deslagging can be accomplished by controlled oxidation conditions in the reactor that vary from one predetermined portion of the reactor to another. Thus, the slag present in one predetermined portion is derivatized and fluidized for removal from the reactor at a faster rate than the slag present in another portion of the reactor, which is not derivatized or is subjected to more limited derivatizing slag conditions. Derivatized slag can be differentiated from non-derivatized slag that does not flow or more limited derivatized slag that has a lower mass flow rate then the derivatized slag at conditions of controlled oxidation. The derivatized slag can then be selectively removed because it has attained a lower fluidizing temperature.

Abstract: A retractable needle syringe of the present invention includes an elongate barrel having an inside surface defining a chamber, an open proximal end and a distal end. An elongate plunger is slidably positioned in fluid-tight engagement with the inside surface of the barrel. The plunger includes a distal end, a proximal end extending outwardly from the open end of the barrel, and a radially directed projection on the distal end of the plunger rod. A movable carrier is positioned in fluid-tight engagement with the inside surface of the barrel, the carrier includes an outside surface, a distal end, a proximal end, and a passageway therethrough in fluid communication with the chamber. The proximal end of the carrier includes an open-ended groove which is sized and shaped to receive the plunger projection. The groove includes an axial portion and a circumferential portion. The plunger is movable axially, distally and proximally, so that the plunger projection can enter and exit the axial portion of the groove. Rotation of the plunger with respect to the carrier causes the projection to enter the circumferential portion of the groovecontaining or trapping said projection so that said plunger rod can apply axially directed force and rotationally directed force to the carrier. A needle cannula projects outwardly from the distal end of the carrier. The cannula includes a distal end, a proximal end and a lumen therethrough in fluid communication with the passagewayof the carrier. Control structure is provided to prevent movement of the carrier with respect to the barrel during normal use of the syringe while the control means is in a first locked position, and the allowing the carrier to be moved proximally into the chamber of the barrel through forces applied to the plunger while the control means is in a second unlocked position.
