Abstract: An optical amplifier comprises an erbium-doped, silica-based optical fibre (6) coupled to a second optical waveguide, comprising a fibre (4) having a D-shaped cross-section. The second optical waveguide (4) has an overlaid grating (10) formed on a silica wafer (9) which is constructed and configured so that the waveguide filter provides loss in transmission substantially at the wavelength of the gain peak of the amplifier. The resonant reflection wavelength is chosen to be substantially equal to, or greater than, the wavelength of the gain peak of the amplified gain spectrum. Transmission losses at wavelengths shorter than the resonant reflection wavelength of the grating act to reduce the gain peak thereby flattening the gain spectrum of the amplifier so providing a larger useful gain bandwidth for optical fibre systems having a cascade of such fibre amplifiers.

Abstract: Compounds are disclosed for treating viral infections due to herpes, influenza, hepatitis B, Epstein-Barr, and varicella zoster viruses, as well as cytomegalovirus and human immunodeficiency virus (HIV) by means of lipid derivatives of antiviral agents. The compounds consist of lipid derivatives of phosphonoacids having antiviral activity which are linked, commonly through the phosphate group of the phosphonoacid, to one of a selected group of lipids. The lipophilic nature of these compounds provides advantages over the use of the phosphonoacids alone. It also makes it possible to incorporate them into the lamellar structure of liposomes when combined with similar molecules. In the form of liposomes, these antiviral molecules are preferentially taken up by macrophages and monocytes, cells which have been found to harbor the target human immunodeficiency virus (HIV). Additional site specificity may be incorporated into the liposomes with the addition of ligands, such as monoclonal antibodies or other peptides or proteins which bind to viral proteins. Effective phosphonoacids are phosphonoformic acid or phosphonoacetic acid; lipid groups may be glycolipids, sphingolipids, phospholipids, glycerolipids, or fatty acids. The compounds persist, after intracellular hydrolysis, as the antiviral phosphonoacids. The compounds are effective in improving the efficacy of antiviral phosphonoacids by prolonging the antiviral activity after the administration of the drug has ended, and in preventing retroviral replication in HIV infections which have become resistant to therapy with conventional forms of the antiretroviral agents.

Abstract: The amount of N2O in flue gases discharged from a fluidized bed combustion system is minimized by effecting vigorous and intimate mixing of the flue gases (with entrained particles) from a fluidized bed by increasing the velocity of the flue gases and then decreasing the velocity from the increased level, introducing a N2O decomposing catalyst into the flue gases and particles immediately after increasing and decreasing of the velocity, and mixing the N2O catalyst with the flue gases and particles, to effect decomposition of the N2O. The catalyst is a calcium based sorbent, such as CaO or limestone, although and other catalysts also may be utilized. Normally the decomposition takes place without increasing the temperature of the flue gases. The increase in velocity is achieved by providing a constriction in the combustor vessel. The interior of the combustor vessel is lined with erosion resistant and thermal insulating material. Where the catalyst is calcium based sorbent, it is calcined, and the calcined particles are removed from the flue gases and recirculated to the fluidized bed, providing at least about 10 to 30% of the calcium based sulfur absorbing sorbent necessary to remove sulfur from the flue gases.

Abstract: A biodegradable interpolymer and composition is prepared by the reactive blending of a synthetic polymer having functional groups with a naturally occurring biodegradable polymer such as a protein compound. During reactive blending, the synthetic polymer can undergo a chemical reaction with the biodegradable natural polymer which results in covalent and physical bonding between the two polymers, thereby forming an interpolymer. By this process, a biodegradable interpolymer composition is produced that is suitable for moulding various articles.

Abstract: In order to validate data manipulation results in a CPU which incorporates duplicate basic processing units or integrity, which BPUs are typically each implemented on a single VLSI circuit chip, and which is capable of performing single and double precision data manipulation to obtain first and second data manipulation results, which should be identical, and a cache unit for receiving data manipulation results from both BPUs and for transferring specified information words simultaneously to both BPUs upon request. These operations are controlled by cache interface control signals identically generated in each BPU. In each BPU, the control signals are arranged into first and second groups which are nominally identical. The first control signal group is transmitted to the cache unit from one BPU while the second control group is transmitted to the cache unit from the other BPU. In each BPU, parity is generated for each control group separately. Parity for the group sent to the cache unit by each BPU is included with the control signal information for checking in the cache unit. Parity for the group not sent to the cache unit by each BPU is transmitted to the other BPU and checked against the locally generated parity for that group. In the event of a parity miscompare sensed in either BPU or a parity error sensed in the cache unit, an error signal is issued to institute appropriate remedial action.

A stepped cutting edge is formed at the intersection of the top face and the side face for engaging a workpiece and removing a chip from it. The stepped cutting edge includes at least two offset edge portions which produce distinct, transversely-spaced chip segments during the cutting operation. The offset edge portions are connected by transition edge portions which are disposed at an obtuse angle with respect to the offset edge portions. The angle of the transition edge portions tends to spread the individual chip segments apart during the machining operation to effect a thinning of the chip between the individual chip segments. The entire cutting edge is helically curved so that the cutting edge lies on the surface of a circumscribing cylinder defined by the rotation of the cutting edge about the axis of the milling cutter.
