Abstract: ABSTRACT OF THE DISCLOSURE      A method is disclosed for treating granular or pulverous raw material in a kiln plant including a preheater stage, a precalciner stage and a separator stage coupled to one another.  Precalcined material is separated after the separator stage into a first and second material flow.          The first material flow is suspended in spent cooling air and fed to a reaction zone zone for burning and melting the material therein. The melted material is fed to a cyclone for separating smoke gases therefrom and thereafter to a rotating nodulisation drum.  The second material flow is also fed to the rotating nodulisation drum and mixed therein with the melted material so as to avoid any sticking and clogging of the melt.  A kiln for practicing the method of the present invention is also disclosed.  In prefered alternative embodiments, the reaction chamber can be either a shaft-like chamber or a cyclone burner.

Abstract: ABSTRACT OF THE DISCLOSURE       An R.F. generator for providing power to a load via a trans-mission line wherein load impedance is automatically matched to the surge impedance of the transmission to provide maximum transfer of energy from the generator to the load.  Voltages representative of input power and reflected power are utilized to control a load match circuit to cause load impedance to equal transmission line impedance.  The load match circuit includes first and second vari-able capacitors and respective stepping motors for varying their capacity.  Bi-directional couplers provide voltage outputs pro-portional to forward and reflected power, and a transmission line connects the bi-directional couplers to the load match circuit. A control circuit is connected to receive the outputs from the coupler means proportional to forward and reflected power and is connected to the load match circuit for energizing the stepping motors to vary the capacitors to cause apparent load impedance to automatically match the surge impedance of the transmission line whereby reflected power is reduced substantially to zero regardless of variations of load impedance.

Abstract: ABSTRACT         The invention relates to a process for producing aroma-containing food products in which the exogenously and/or endogenously formed enzyme complexes are separated from specific pure or mixed cultures of microorganisms, which develop certain characteristic flavouring and aromatizing agents. The enzyme complexes are subsequently added to an aqueous solution or suspension of a substrate. The isolated enzyme complexes are optionally concentrated or standardized beforehand under careful conditions. The mixture of the substrate and enzyme complexes subsequently undergoes biochemical rapid ripening under suitable conditions until the desired aromatizing and flavouring agent concentration is obtained. The biochemical rapid ripening is then terminated by substantial inactivation of the enzyme complexes. The ferment solution or suspension obtained and which contains the desired flavouring and aromatizing substances, can be added to basic food substances for aromatizing them.

Abstract: ABSTRACT         A gating circuit for gating a minimum duration input signal on one of a plurality of input lines (10) to a respective output line (16).  The input lines (10) are coupled to a latch (15) comprising flip-flops and the   latch is enabled when a signal is applied to a clock input (18).  The input lines (10) are coupled to a verifier circuit (25) which includes a verifier gate (27) receiving direct and delayed signals from a NAND gate (32) connected to the input lines (10).  The verifier gate (27) applies a signal to the clock input (18) when both inputs (28,29) are simultaneously receiving a signal so that signals less than the minimum duration do not result in a signal at clock input (18).  The NAND gate (41) applies a signal to locking gate (44) when any one output (16) of latch (15) is energised, and the output (47) of locking  gate (44) holds a disabling signal on clock input (18) so that only the first input signal on a line (10) will be latched.  A reset means (50) including reset gate (51) and switch (53) enables resetting of the latch (15).

Abstract: ABSTRACT OF THE DISCLOSURE         In the manufacture of non-returnable packages for milk and other beverages laminated packing material is seal-ed to itself along linear sealing zones by causing outer thermoplastic layers of the packing material to fuse together.          The strength of the seal obtained depends upon the thermo-plastic surfaces being free of impurities, e.g., oxide coat-ings or residues of the contents of the package.  In spite of the presence of impurities a strong seal can be obtained if the thermoplastic layers, within a limited region of the seal-ing zone, are pressed against each other with such a force that molten thermoplastic material is made to flow to adjoin-ing regions, since in this case the thermoplastics are blend-ed to such a degree that the seal-preventing layer of impuri-ties is broken.

Abstract: ABSTRACT OF THE INVENTION           Disclosed is a fastener assembly for attaching articles to a penetrable wall comprising a threaded fastener having a threaded shank and an anchor member capturing the threaded shank.  Means are provided for retaining the anchor member in a first position substantially parallel to the axis of and partially embracing the threaded shank while the fastener, carrying the anchor member, pierces the wall.  The threaded shank has a length sufficiently greater than the length of the anchor member to allow the threaded shank to extend beyond both ends of the anchor member when the anchor member is in the first position.  The anchor member further has spring means which, after the anchor member has passed fully through the wall, aids rotation of the anchor member from the first position to a second position sub-stantially oblique to the axis of the threaded shank and wherein the shank and anchor member are in threaded engage-ment with each other.  The threaded shank has at least two thread segments of different major diameters with the thread segment having the largest major diameter being first to pierce the wall during installation of the fastener assembly.          When the fastener is subjected to a force in a direction to retract the fastener through the wall after spring aided rotation of the anchor member toward the second position and the anchor member is brought to bear against an inner surface of the wall, thereby positioning the fastener to be threadedly advanced through the anchor member, the threaded shank will be prevented by the largest major dia-meter threaded segment bearing against the anchor member, from pulling through the anchor member and allowing the anchor member to fall free.
