Abstract: ABSTRACT OF THE DISCLOSURE:            A paper machine has an enclosure for containing a gas under pressure.  A hydraulic headbox of the paper machine includes a slice as well as a conductor structure for con-ducting suspension to the slice and a distributor structure for distributing suspension as uniformly as possible to the conductor structure to be conducted thereby to the slice.          The gas enclosure and distributor structure respectively have hollow interior portions communicating with each other so as to provide for the suspension in the distributor portion a free surface acted upon by gas under pressure in the enclosure so that this latter gas under pressure will act as a gas cushion for damping pressure variations in the stock suspension.

Abstract: ABSTRACT OF THE DISCLOSURE A device for discontinuing and automatically restoring the operational function of a spring brake actuator.  In the force transmission path between the actuator piston, movable in a cylinder in a brake application direction under the action of a working spring, and a non-rotatable piston rod there are two means coaxial with the piston rod and in non-self-locking thread engagement with each other.  Of these means one is non-rotatable and the other rotatable but releasably locked to the cylinder in its spring force transmitting rotational direction.

Abstract: ABSTRACT OE OF DISCLOSURE            A test composition, device, and method for their use in a homogenous specific binding assay which employs a sub-stance having reactant activity, i.e., a reactant, as a labeling substance in the detection of a ligand in a liquid medium   The test composition and device comprise a conju-gate formed of a specific binding substance coupled to the reactant.  The reactant advantageously is an enzymatic reactant such as an enzyme substrate or coenzyme.  The activity of the conjugated reactant as a constituent of a predetermined reaction is affected by reaction between the specific binding substance in the conjugate and a specific binding counterpart thereto.  The presence of a ligand in a liquid medium may be determined using competitive or displace-ment binding or sequential saturation techniques wherein the specific binding substance in the conjugate is the ligand or a specific binding analog thereof, or using a direct binding technique wherein the specific binding substance is a specific binding partner of the ligand.  The effect of the specific binding reaction on the activity of the conjugated reactant is related to the presence or amount of the ligand in the liquid medium tested.

Abstract: A B S T R A C T     An apparatus for varying the intensity without changing the color quality of light derived from an artificial light source.          The apparatus is used as the main reflector portion of a lamp including a light source with a first reflector situated to direct light at the apparatus.  The apparatus includes an arcuate row of pivotally mounted cylinders. Each cylinder has at least two surface areas of different reflectivity.  Thus, control of the orientation of each cylinder will provide a selectively variable composite reflectivity for the cylinders.  As reflected light constitutes the primary output of the lamp, control of the cylinders results in control of the light intensity output of the lamp .

Abstract: ABSTRACT OF THE DISCLOSURE         A design technique is provided, with method and apparatus for controlling the bypass gas stream pressure and varying the bypass ratio of a mixed flow gas turbine engine in order to achieve improved performance.  The disclosed preferred embodiments each include a unique mixing device for combining the core and bypass gas streams which includes means for varying the area at which the bypass stream is injected into the core stream.  The variable area mixing device permits the static pressures of the core and bypass streams to be balanced prior to mixing at widely varying bypass stream dynamic pressure levels.  The ability to balance the core and bypass stream static pressures at widely varying bypass stream dynamic pressures permits the mixed flow gas turbine engine of this invention to operate efficiently over a wide range of bypass ratios and further permits the dynamic pressure of the bypass stream to be maintained at a level which will keep the engine inlet airflow matched to an optimum design level throughout a wide range of engine thrust settings.  To further assist in maintaining a static pressure balance between the core and bypass streams prior to mixing, the variable area mixing device may be provided with means to accelerate the bypass stream to supersonic velocities immediately prior to mixing combined with means to control the degree of expansion of the bypass stream after it has been accelerated to supersonic and before it is mixed with the core stream.  To increase the flexibility in adjusting the dynamic pressure of the bypass stream and provide the potential for a relatively high thrust level without the use of an afterburner, the system may be modified by the use of a split fan section in conjunction with two concentric bypass ducts.

Abstract: PROCESS AND APPARATUS FOR MEASURING THE CONCENTRATION OF GASEOUS OXYGEN, CARBON MONOXIDE AND CARBON DIOXIDE IN GASEOUS OR LIQUID SAMPLES, IN PARTICULAR IN BREATH AND BLOOD SAMPLES                     ABSTRACT OF THE DISCLOSURE      For measuring the concentration of oxygen, carbon monoxide and carbon dioxide in a gaseous or liquid sample, a reaction mixture is used which changes colour in a characteristic manner due to the presence of the respective gas component.  The gaseous or liquid sample is continuously mixed with the reaction mixture maintaining a constant mixing ratio and conveyed through a flow cuvette which is photometrically analysed.  Alternatively, the sample is injected into a hermetically sealed test cuvette con-taining the reaction mixture which characteristically changes its colour by contacting it with the sample.  After a pre-selected reaction time the change of extinction is photometric-ally determined as a measure for the wanted gas component by comparison with a standard reference value.  The test cuvette is sealed with a gas-tight membrane comprising several super-imposed layers of an elastic support material.            Le A 17 979
