Abstract: Abstract A pneumotachograph including a housing having first and second ports which, during the course of respiration, alternate as input and output ports and which provide a path for generally linear flow of the respiratory gases.  A pair of pitot tubes are disposed along the top of said path and are positioned generally at right angles thereto.  A pair of baffles or flow deflectors are disposed in the path in alignment with the axes of the pitot tubes.  Each of the baffles is positioned at an angle of approximately 45° to the axis of its associated pitot tube and to the path of flow.  The baffles serve to reflect the respiratory gases upwardly toward the pitot tubes but since the pitot tubes are arranged above the baffles gravity prevents the heavier mucus, water and nongaseous materials from entering the pitot tubes.  Rather, these heavier particles run up to and over the top of the baffle.  The baffles may be held in the flow path by a rigid connection or alternatively, they may be retained there by a resilient connection such that the pitot tube measurement is linearized.            In another embodiment, the baffles may actually be merged into a single baffle thus leaving an annular opening between itself and the housing with the opening of the gap being approximately the same distance as the distance between the pair of tubes.  Here the mode of operation is a pressure build-up upstream in proximity to the one tube and then a venturi effect downstream for lower pressure in proximity to the other tube.

Abstract: ABSTRACT OF THE DISCLOSURE     A system for measuring the values of a parameter, such as basis weight or moisture content, of a sheet of material is provided.  The system includes a scanner head, having a radiation source and detector, which can pass transversely across the sheet material as the sheet material is fed axially.  The head has a gap which accommodates the sheet material.  The amount of radiation detected provides an indication of the parameter in question.  It has been found that the precise spacing of the gap influences the results and so the invention provides a distance correction system to correct the measured parameter for variations in the gap dimension.

Abstract: ABSTRACT OF THE DISCLOSURE     DIRECT CONTACT WATER HEATER          This invention relates to an improvement in direct contact water heaters and methods of effecting heat exchange between hot gas and cold water.  In a typical direct contact water heater cold water is sprayed downwards within a main chamber where it meets hot gas passing upwardly in a counter-current fashion.  A direct contact water heater according to this invention includes an antechamber through which the hot gas is passed before entering the main chamber.          The hot gas passing upwardly in a counter-current fashion to hot water which is at a temperature higher than the dew point of the gas raises the dew point of the hot gas before it enters the main chamber so that the cold water entering the main chamber is heated in an efficient manner to higher temperatures than could otherwise by achieved with the preservation of good efficiency.

Abstract: Abstract of the Disclosure A composition and method useful in measuring anti-streptolysin O in a blood sample based on the reversible inhibition or inactivation of SO hemolytic activity via pH is herein disclosed.  The composition comprises a solution of Streptolysin O having a pH outside the range of about 4.8 to about 9Ø  The method includes the step of adjusting the pH of an SO solution to a pH outside the range wherein SO possesses hemolytic activity.  More specifically, the method comprises mixing at least one sample of non-hemolyzed blood or serum with at least one predetermined quantity of Streptolysin O (SO) in a non-hemolytic solution having a pH outside the activity range of SO, the SO having a known hemolytic capacity.  Then, each solution is incubated at a temperature of about 0-50°C for a time sufficient to allow any ASO in the sample to react with the SO.  The hemolytic activity of the SO is restored by adjusting the pH of each in-cubated solution to a range within a pH of about 4.8 to about 9.0, whereby any free SO in excess of the amount required to react with the ASO can lyse blood.  Finally, the presence or absence of lysis in each solution is detected.

Abstract: Abstract Multifilament bundles are impregnated with an ultraviolet curable resin to form a composite material suitable for use as a strength member in cables and other applications.  The coating material is desirably a bisphenol-A-diglycidylether diacrylate resin and a diluent therefor.  The inventive coatings obtain good wetting of the filaments, allowing rapid penetration into the roving or yarn.  A much faster coating and curing operation is obtained as compared to prior art methods.  Glass fiber strength members made by this technique are especially advantageous for use in optical fiber cables where high strength and a low thermal coefficient of expansion are desired, as well as nonconductivity to protect against lightning strikes.

A speed change mechanism is contained within the engine case along with the output shafts and includes a first transmission shaft between the crankshaft and one of the output shafts.  In one embodiment, the cylinder block of the engine is illustrated as being inclined toward the speed change transmission such that the cylinder block, cylinder head and head cover do not extend laterally outwardly beyond the engine case.  To employ both output shafts, sprockets are arranged on each shaft with a coupling chain.  The orientation of the output shafts provides for a narrower engine profile.
