Abstract: ABSTRACT A pneumatic insert for a pneumatic tire comprises a generally toroidal-shaped hollow member having a pair of annular insert beads with sidewalls extending therefrom joined to an insert crown portion. Each insert bead has a foot portion with a project-ing elastomeric formation at the bead heel to furnish an inner bead diameter at the heel that is less than the inner bead diameter at the toe.           In at least one embodiment of the invention the bead heel projection is of tringular shape with a vertex of the triangle defining the first inner bead diameter.

Abstract: ABSTRACT OF THE DISCLOSURE       An RF amplifier stage of an AM broadcast tuner is disclosed wherein, depending upon the power level of the received input signal, said input signal is amplified by a high gain radio fre-quency amplifier, or by a low gain radio frequency amplifier, or by a combination of both the high and low gain radio frequency amplifiers at intermediate levels. This system provides wide dynamic range and low distortion in that it prevents amplifier saturation and reduces intermodulation product signal levels.

Abstract: ABSTRACT OF THE DISCLOSURE    An automatic compression release mechanism for an internal combustion engine wherein first and second opposed cantilevered ends of a centrally supported flexible plate forms two independently operating valves to respectively control serially connected inlet and outlet ports of a valve chamber forming a part or a compression release passageway connecting the combustion chamber of the engine with a zone of lower pressure such as the cylinder sidewall exhaust port of a two-cycle engine.  The valves are each one-way check valves operating oppositely to one another.          The valve controlling the outlet port is normally biased to an open position and remains open when the engine is turned over at the relatively slow cranking speeds nor-mally used to start the engine, relieving somewhat engine compression, thereby facilitating the starting of the engine.  The outlet valve is flexed to a closed position in response to a rapid pressure build-up in the chamber caused by ignition of the fuel-air mixture in the engine combustion chamber, thereby sealing the compression re-lease passage after the engine starts.  A restricted passageway from the compression release chamber to the zone of lower pressure, such as the cylinder sidewall exhaust port, which passageway is independent of the chamber valves, slowly diminishes the chamber pressure to release each valve to return to its respective open position a predetermined time after the engine stops running.  The restricted passageway and the outlet port of the compres-sion release chamber may both be connected to the cylinder sidewall exhaust port by a hollow interior portion of the engine piston pin.

Excess steam is tapped off the steam to be supplied to the heat exchanger (6) and supplied to the first drying stage (2) operated with saturated steam. Finally, the solid materials are, after having been centrifuged, removed from the steam atmosphere and pressure  released, whereupon the solid materials are, if desired, immediately transferred to a hot briquetting plant (13).

Abstract: HYDRAULIC CONTROL FOR A POWER TRANSMISSION            Abstract of the Disclosure:         A hydraulic control for a power transmission has a regulator valve for controlling the hydraulic system pressure and a plurality of shift valves for controlling the automatic ratio change in the trans-mission.  The shift valves are urged toward the higher ratio position by a governor pressure.  The shift valves, except the 1-2 valve, are selectively sub-jected to separate modulated throttle valve pressures acting in opposition to the governor pressure and depending upon whether the respective shift valve is in the lower or higher ratio position.  The modulated pressures are maintained at substantially zero for a portion of the throttle valve pressure range so that upshifting and downshifting will be sensitive to governor pressure and therefore vehicle speed only.         The regulator valve is subject to a variable bias pressure which is proportional to throttle valve pressure.  The bias pressure is controlled by a valve to be equal to the throttle pressure during the lower pressure portion of the throttle pressure range and to increase at a rate less than the throttle valve pressure during the remainder of the pressure range.
