Abstract: A tuneable laser is disclosed, including a gain section with first and second comb reflectors to one side thereof. The two reflectors each provide combs with substantially uniform spacings, the spacings differing as between the combs. Each comb reflector can be tuned so as to shift the reflective peaks of the combs, thus allowing alignment of a single reflective peak at a chosen wavelength which is the same in both combs, forming a supermode. This supermode has an intensity greater than the threshold of the gain section and thus the laser produces an output at that selected wavelength.

Abstract: The present invention pertains to compositions having improved delivery of pharmaceutical actives. These compositions comprise pharmaceutical actives in an anhydrous solvent. These compositions may take the form of liquid elixirs placed into the mouth and eventually swallowed, or can be delivered via liquid-filled drops, metered liquid dosing devices, atomizers and liquid-releasing, edible capsules.

Abstract: The present invention is an orally administered liquid pharmaceutical composition that demonstrates excellent physical stability while delivering concentrated levels of the pharmaceutical active(s). Specifically, these compositions for extended periods do not allow the active to precipitate or settle out of solution.

Abstract: A multi-wavelength optical reflector comprises a diffraction grating structure (18) which comprises a plurality of repeat grating units (20) in which each grating unit (20) comprises a series of adjacent diffraction gratings (22, 24, 26) having the same pitch. The grating units (20) and adjacent gratings within a grating unit are separated by a phase change (28) of substantially pi (&pgr; radians). The lengths of the gratings (22, 24, 26), which are different for each grating within a grating unit, are selected so as to provide a predetermined comb reflection spectrum which comprises a plurality of reflection maxima of substantially equal reflectivity.

Abstract: The array is highly suitable for producing a spacially wide output “beam” (comprising a number of individual beams). It suffers less from problems of hotspots and filamentation since each tapered laser supports a limited number of modes, or even a single mode. Therefore it produces a semiconductor laser which is especially suitable for pumping of other lasers and to be used in materials processing.

Abstract: An apparatus for carrying by a diver while under water (and at the surface between dives) provides information useful for enabling the diver to ascend therefrom both expeditiously and safely in order to avoid decompression sickness. A corrosion-resistant ceramic transducer (60) provides an electrical capacitance responsive to the pressure of the water thereon, in an electronic circuit (52), comprising also a resistance (61), for providing a signal (at 53) responsive to the time constant therein and substantially unaffected by normally encountered variations in supply voltage. Electronic data processing means (40-51), responsive to the signal, computes the water pressure, the depth of the transducer (60) in the water, the minimum depth to which the diver can from there ascend safely, the minimum time within which the diver then can ascend safely to the surface of the water, and the elapsed time since the beginning of the dive. Displays (48, 49) provide indications to the diver of the computed values.

Abstract: A multi-ply dunnage bag is provided with an end closure which is both strong and easy to fabricate. The first wall of the dunnage bag has, at one end, an extension or flap on the end of each ply. The flaps on each ply of the first wall are segregated into pairs of adjacent flaps and the two flaps that make up each pair are secured together and folded over the end of the bag where they are inserted between two adjacent plies of the opposite, or second wall and wherein at least one of the flaps of each pair is secured to one of the plies of the second wall. An identical end closure is provided at the other end of the bag, but with the plies of the second wall having flaps folded over and secured to the first wall.

Abstract: An inflatable dunnage bag having a relatively thin-film, flexible, gastight bladder is provided with a fill valve device extending from the exterior of the bag to the interior of the bladder. The fill valve device includes a hollow housing which is mounted on one end by means of a flange to the outer surface of one wall of the bladder. Within the housing there is an orifice and a plug member which is spring-biased in sealing engagement against the orifice. The plug member extends beyond the end of the housing and into the bladder. A flange on the end of the plug member in the bladder is substantially parallel to, and spaced away from, the mounting flange/bladder wall interface to provide a separation of the bladder walls, to deflect the filling gas to prevent impingement upon the bladder wall opposite the housing, and to provide an anti-blowout stop thereby preventing the plug member from being blown out of engagement with the valve housing when the bag is subjected to high compressive loads.
