Abstract: ELECTRONICALLY COMPENSATED ROTATING GAS CELL ANALYZER                      Abstract of the Disclosure In a gas analyzer a beam of radiant energy is passed through a rotating gas cell which alternately inserts optically transmissive chambers into the path of the beam.          One chamber contains a quantity of gas of the species to be analyzed at a pressure that produces sharp absorption lines.          The other chamber is provided with either a quantity of gas at a pressure that produces substantial line broadening or a neutral density attenuator.  In either case the chambers are made to have substantially equal average transmissivity over the spectral band of interest.  The beam is then passed through a sample region in which the gas species concentration is to be measured.  The beam is then detected by a photodetector.     A filter, usually associated with the photodetector, limits the radiant energy response to a spectral region where the gas species to be measured displays suitable absorption lines.            An electronic system amplifies the photodetector output and demodulates that signal component which occurs at a frequency corresponding to the cell rotation rate.          In the absence of the particular gas in the sample region the two cell chambers have equal average transmissivity, and there should be no such component.  However, if a quantity of the gas species to be measured is present in the sample region, a rotation rate signal component will be present and will be in proportion to the total quantity of that gas species in the sample region.            In practice it is difficult to precisely balance the cell transmissivity values and, even if achieved, such balance is difficult to maintain.  Accordingly the electronic amplifier is gain modulated at the cell rotation rate so that residual optical unbalance is corrected electrically.     Since this correction is accomplished multiplicatively, it is independent of optical and electronic gain and loss values.

Abstract: ABSTRACT OF THE DISCLOSURE      A photocoagulator is described incorporating a selected light source.   The selected light source is a waveguide laser of the type using an active liquid comprising a dye in solution.  The laser is so constructed that a cell containing the active liquid and a reservoir, rigid with the cell, for replenishing the liquid in the cell, form a single unit which can be readily removed from the remainder of the laser.          An optical pumping source which forms part of the remainder of the laser is arranged to set up a heat gradient in the cell which tends to collimate the stimulated emission in the cell thus avoiding the need for accurate alignment of the reflectors at opposite ends of the cell.

Abstract: ABSTRACT OF THE DISCLOSURE     The instant invention provides an improved method for determining the streaming velocity of a streaming liquid by injecting a thermopulse into the liquid and measuring Its transit time.  The pulse is detected by its ascending flamk at downstream points and by its ascending or descending flank at its point of injection. For short transit times, provision is made to eliminate the neat up time of the heating wire imparting the pulse from the transit time measurement.  The liquid may stream continuously or discontinuously, and if the latter, provision is made to decay measurement on initiation of flow until the flow pattern has stabilized.  The time is determined by counting pulses from a pulse generator during the period the pulse is traveling between the point of injection and a detection point or between two detection points.  This procedure enables more precise measurement of flow than has heretofor been possible. The present invention is also concerned with a method and an apparatus which permit accurate and reproducible dosing for multicomponent liquid systems.  Previously known systems were dependent upon such variables as pump pressure, density, viscosity and temperature of the components but the present invention provides a mon-itoring and metering system independent of these variables and is able to provide reproducible dosing at the low (50 to 200 cm3/min, for example) flow rates utilized in spray lacquering.  The method is based on the fact that the particular components are conveyed through separate pipes into a mixing chamber. The flow rate at least one of the pipes is determined by the above procedure and the flow in the other pipes is then adjusted automatically to be in a fixed ratio to the first flow. The so-measured transit time is converted into an inversely proportional voltage and the flow rate in the other pipes is adjusted proportionally to this voltage. An apparatus is provided for practicing the method. The apparatus comprises flow measuring elements which are electrical connected in the pipes leading to the mixing chamber.

The passage communicates at one end with a source of gas (air) under pressure and, at its opposite end, is vented to discharge a continuous stream of gas whenever the unit is in operation.  When the resilient sleeve is squeezed anywhere along its length, back pressure is created which acts upon a pressure-responsive pilot valve, the pilot valve in turn regulating the speed of the dental handpiece in accordance with the amount of back pressure developed.

Abstract: ABSTRACT OF THE DISCLOSURE         A container with a heat-securable tamper-indicating wax-coated closure sheet is disclosed herein. The container comprises a base with a sidewall extending upwardly from the periphery of the base and defining a substantially circular open top, or mouth.  A square-shaped sheet of flexible closure material is disposed over the rim of the mouth of the container and is engaged between the container rim and a superposed container lid.          Each of the four corners of the sheet extend beyond the periphery of the lid to form tabs which project downwardly alongside the container sidewall and are heat-sealingly secured thereto.  The container lid is seated in the open mouth of the container and over the major portion of the closure sheet, so that only the tabs are exposed.  If one of the tabs is detached from the con-tainer sidewall, a visual indication is given that the container may have been tampered with.  The lid is not sealed to the closure sheet, so that the lid may be removed, if desired, without dis-turbing the closure sheet.  The midportion of the lid is dished, or recessed downwardly, so that the containers can be readily stacked upon one another in a retail outlet.

Abstract: NOISE FILTERING DEVICE                 ABSTRACT OF THE DISCLOSURE   A device for removing undesired correlated signal components, such as noises, hum, tones, echoes and resonances from degraded voice, music or other desired audio signals and records, without requiring a second signal source correlated with the undesirable effects to be removed.  In a first embodiment, an optimal linear estimator, such as a Wiener filter, is used to develop a least mean square estimate of the correlated signal components in an input voice signal.  A combiner combines the least square estimate with the input voice signal to develop an output voice signal which contains only uncorrelated signal components (in a long-term sense).          The output voice signal may be further applied to a spectrum shaper to restore the long term spectrum of the uncorrelated signal components to its desired shape.
