Abstract: ABSTRACT OF THE DISCLOSURE           An axial flow gas turbine engine is provided with a plurality of combustion chambers distributed circumaxially about the engine axis and a plurality of transition ducts which carry propulsive gases between the burners and an annular turbine inlet at a bulkhead between the combustion and turbine sections of the engine.  Support for the transition ducts at the turbine inlet is provided by an outer support ring fixedly secured to the engine bulkhead and an inner support ring which is held by a plurality of struts from the outer support ring.  Flexible sealing means extend between the inner support ring and the bulkhead adjacent the turbine inlet to permit the inner ring to expand or contract radially with the transition ducts and at the same time to prevent compressed air from flowing directly into the turbine section.  The outer ring and the flexible sealing means are apertured to permit a limited flow of rel-atively cool compressor air to enter the turbine along with the propulsive gases and thereby cool the support structure and the inlet guide vanes of the turbine.

Abstract: ABSTRACT             A rotary sample changer for a spectrofluorometer has a revolving turret base which can be indexed and which carries an interchangeable sample carrier.  Different sample carriers accom-modate test cells, test tubes and cuvettes of different sizes and shapes. The revolving turret base and the interchangeable rotary sample carriers are constructed of material having good thermal conductivity and rotate on a large stationary hollow axle which is thermostated by thermally controlled internal fluid cir-culation to act as a heat source or sink to the samples.  Thus, the sample carriers can readily be interchanged without disturbing the plumbing by which the thermostatic fluid is circulated.            The revolving turret base is detented at the stations to which it is indexed without kinematic ambiguity and without application of any cocking force.  Two spring biased ball detents, symmetrically spaced 180° about the axis of rotation, are provided At the four index stations one ball catches on one of two indexing grooves spaced 90° apart, while the other ball bears against a flat.

Abstract: ABSTRACT OF THE DISCLOSURE          Seed and/or fertilizer or similar particulate material is fed by a seed cup assembly or the like from a hopper to a main conduit through which air is passing at a rate sufficient to ensure that the material is picked up by the air stream and transported thereby.  A main distributor head receives the material and feeds it pneumatically to a plurality of secondary distributor heads.  A plurality of feed conduits extends from each secondary distributing head one to each of the seed outlets provided adjacent the furrow openers of the assembly.  Each distributor head is provided with tapered restrictors which concentrate the material centrally so that it strikes the curved upper end centrally and is thus spread evenly to all of the conduits extending from the manifold thus ensuring even distribution of the material.

Abstract: ADAPTIVE AUDIO COMPRESSOR                      ABSTRACT    An amplitude, modulated transmitter includes an audio amplifier which, via a radio frequency (RF) power supply modulator, modulates an RF amplifier and carrier. Fluctua-tions in the direct current DC bias to the RF amp, such as are common in mobile applications, vary the modulation index of the transmitted signal.    To minimize DC bias affects on the modulation index, the invention contemplates an audio compressor which senses both audio signal level and DC bias level and, in response thereto, controls audio signal compression to maintain the desired percent modulation.  Compression is effected by changing the bias on a semiconductor device which, in turn, attenuates audio signals at the input of a fixed gain audio amplifier.  A feedback path around the audio amplifier senses both DC voltage and audio signal level and produces an appropriate control signal to bias the semiconductor device, thereby altering audio compression.

Abstract: ABSTRACT        A high speed technique is provided for analyzing the shape of the amplitude envelope of a diffraction pattern's first order side lobe resulting from passing coherent light through a fabric material to be inspected.  The light inten-sity of the lobe is scanned from one side of the lobe to the other by a linear photo-diode array to provide successive voltage signals whose respective voltage values are a function of the light intensity at successively spaced increments from one side of the lobe to the other.  Each of these successive voltage signals are compared with a series of reference voltages of substantially less number than the number of spaced increments, each reference voltage having a value greater than the value of the preceding reference voltage in the series to define a voltage range encompassing the highest voltage in the series of voltage signals.  A numerical count is then provided of those voltage signals which have voltage values falling between the values of adjacent refer-ence voltages. in the series of reference voltages so that a plurality of counts is provided which indicates the amplitude distribution of light in the light lobe.  The plurality of counts is  substantially less in number than the number of spaced increments thereby reducing storage data requirements in the analysis of the amplitude envelope of the light lobe. Successive first order side lobes developed by successively passing the light beam through different areas of the fabric to cover a large area are analyzed to provide a succession of the pluralities of counts.  The mean values of these succes-sions of pluralities are computed and a subsequent one of the pluralities of counts can then be compared to the mean values and any deviation therefrom by a given amount indicates a change in the quality of the fabric.
