An inhalable lidocaine solution for treatment of asthma and a method for treatment of asthma with the reduced need for concurrent administration of oral corticosteroids in asthmatic patients. The lidocaine solution or lidocaine dry powder is delivered by an electronic nebulizer or by dry powder inhaler or dose meter one to several times a day.

The invention relates to a shock-proof electric marine engine e.g. an engine or generator, for a marine (Navy) ship, comprising a stator and a rotor in a housing, whereby the stator and the rotor are connected in such a way that they are rotatably displaceable in a counter direction and in a radial/axial manner with limited slack. Said rotor and stator form a displaceable unit in relation to the housing, which can be displaced away from the housing with a higher vibration overshoot range. Said housing is elastically connected to the marine(navy) ship.

A simple, reliable, easy to use method for calculating bandwidth data of very narrow band laser beams based on bandwidth data obtained with a spectrometer in circumstances where the laser bandwidths are not large compared to the slit function of the spectrometer. The slit function of the spectrometer is determined. Spectral data of the laser beam is measured with the spectrometer to produce a measured laser beam spectrum which represents a convolution of the laser beam spectrum and the spectrometer slit function. This measured laser spectrum is then mathematically convolved with the slit function of the spectrometer to produce a doubly convolved spectrum. Bandwidth values representing true laser bandwidths are determined from measured laser spectrum and the doubly convolved spectrum. Preferably the true laser bandwidths are calculated by determining the difference between “twice a measured laser bandwidth” and a corresponding “doubly convolved bandwidth”. This method provides an excellent estimate of the true laser bandwidth because “twice the measured laser bandwidth” represents two laser bandwidths and two spectrometer slit function bandwidths and the “doubly convolved bandwidth” represents one laser bandwidth and two spectrometer slit function bandwidths. Thus, the difference is a representation of the true laser bandwidth. In a preferred embodiment the bandwidth parameters measured are the full width half-maximum bandwidth and the 95% integral bandwidth.

A tangential fan, configured to recirculate a lasing gas mixture, has blade members, which are twisted in a substantially helical fashion about the rotation axis of the fan. The circumferential number of blade members can be constant variable between the end flanges. The circumferential position of blade members can shift monotonically or reversibly between the two ends. A tangential fan in accordance with the invention can be made using a conventional method of brazing together individually stamped and formed blade members and hub members. Finishing processes typically include post-machining, electropolishing, and electroless nickel coating.
摘要:
A tangential fan for recirculating a lasing gas mixture has blade members, which vary in circumferential position stepwise from end to end. The number of blade members can be constant or variable between ends. The circumferential position of blade members can shift monotonically or reversibly between ends. Blade members are stiffened by one or more transverse annular hub members. A method of forming a tangential fan involves forming monolithic structures by casting or by machining from a solid block. Two or more monolithic structures can be joined together, typically by electron-beam welding. Casting, welding, and machining processes introduce no additional contaminants. Tangential fans produced have mechanical rigidity, accurate tolerances, and low contaminant concentrations. Methods provided by the invention facilitate forming of blade members into an air foil shape. Finishing processes typically include post-machining, electropolishing, and electroless nickel coating.
摘要:
A very narrow band pulse excimer laser capable of producing pulses at a rate in the range of about 500 to 2000 Hz with enhanced energy dose control and reproducibility. A prior art burst mode "slug effect" occuring at one gas circulation time after the beginning of a burst of pulses is eliminated by the addition of a minute quantity of oxygen. In a preferred embodiment very narrow bandwidth is achieved by reducing fluorine partial pressure to less than 0.10 percent and by increasing the reflectance of the output coupler to greater than 25 percent. In a preferred embodiment, prior art fused silica beam expansion prisms used in the prior art line narrowing module were replaced with calcium fluoride prisms.
