Abstract: HIGH FREQUENCY DIFFUSION MUFFLER FOR GAS JETS     Abstract of the Disclosure A dissipative-type muffler for attenuating the high velocity discharge of a high pressure-high temperature safety valve.  A path of flow constituting four stages of controlled turbulence suppressed diffusion is formed internally of the muffler extending from an intake into a plenum chamber then dis-tributed past a plurality of parallel arranged radial diffuser flanges and an acoustical liner before exiting to atmosphere at relatively low velocity and low noise level.  Laminar flow to small scale turbulence is obtained in the first stage by a jet impingement directional reversal in a controlled spacing discharge from an intake pipe within the plenum chamber.  In the second stage, small scale discharge turbulence of high fre-quency is achieved by laminar flow induced via radial diffusion through controlled gap spacings between the diffuser flanges.          Buffer plate impingement of the second stage discharge is then effected in the third stage after which high frequency noise attenuation by means of an acoustical composition is obtained in the fourth stage before exiting to atmosphere.

Abstract: SEAT BACK LATCH MECHANISM              ABSTRACT OF THE DISCLOSURE      A seat back latch mechanism for a vehicle seat assembly having a generally horizontal seat structure and an upstanding backrest structure pivotally supported on support arms for tiltable movement over the seat structure.   A latch pawl pivotally mounted on one of the structures is maintained in a cam controlled latching attitude relative to a fixed detent on the other of the structures.  The latch pawl is constructed and arranged so that its center of gravity normally provides a force couple acting eccen-trically of the pawl pivot axis to cause the latter to swing out of the controlled latching attitude in a direction to bypass the detent when moderate force is applied to the seat back structure to tilt the latter over the seat structure.      Upon the occurrence of a vehicular deceleration rate sufficient to overcome the inertia of the seat backrest structure which normally resists tilting movement of the latter over the seat structure, the inertia of the latch pawl becomes a factor in causing the latch pawl to engage the detent to prevent tilting movement of the backrest structure.

Abstract: Abstract of the Disclosure According to the invention pulverized brown coal is processed by heating brown coal in two stages.  During the first stage brown coal being processed is heated by a gase-ous heat carrier to a temperature at which thermal decomposi-tion of the brown coal begine.  During the second stage the brown coal being processed is heated by the gaseous heat carrier to a temperature at which an intensive thermal decom-position of the brown coal takes place.  The stream of the gaseous heat carrier delivered at the second stage of heating is fed with air oxygen and with low-grade products, such as heavy tars and pyrogenic water being sprayed into the gaseous heat carrier.      Air oxygen being fed into the gaseous heat carrier as well as heavy tars and pyrogenic water being sprayed into the same raise the combustion temperature of the solid product being obtained and prevent the necessity of purifying the pyrogenic water before disposal thereof into pools.  Power consumption required for carrying out the proposed method is approximately the same as that in conventional methods.
