Abstract: ABSTRACT A system is disclosed for extracting parti-culates from the exhaust gas flow flow an internal com-bustion engine for an automobile by the use of a filter trap stationed adjacent a heat controlled zone of the automobile, and which system periodically cleanses the filter trap of the particulates.  The system has an apparatus which channels the flow of the exhaust gas between a condition where the exhaust gas is carried through at least a portion of the filter trap for an extraction mode and a condition where the exhaust gas is diverted away from said portion of the filter trap during a cleansing mode of said portion.  The apparatus com-prises: (a) walls defining a primary flow channel for normally guiding said exhaust gases through at least a portion of said filter trap, the walls comprise a roof juxtaposed said zone: (b) means defining a diversion flow channel for diverting the exhaust gases away from said portion during the cleansing mode, the diversion flow means being superimposed on the roof of said walls to normally insulatingly separate the primary flow channel from said zone; and (c) flow diverter means for directing the flow of exhaust gases through said primary flow channel and through the diversion flow channel.         The walls defining the primary flow channel Comprises a tube with an expanding conical inlet section, the tube having a cross-section with a height no greater than substantially one-half of its horizontal dimension, the top of the tube forming said roof.  The roof pre-ferably extends horizontally and the diversion flow channel is defined by a wall extending across the roof to form the diversion flow channel therebetween.

Abstract: ABSTRACT    The invention relates to method and apparatus for the combustion of fluidal fuels. The fuel is dispersed in combustion air and, in order to improve the combustion rate and efficiency, is exposed to a high particle velocity of a sound produced by a low frequency sound generator. The frequency of the sound is determined by the sound generator, the maximum frequency being 30 Hz.          A reciprocating movement of combustion air and fuel particles entrained therein is obtained. The sound generator is a quarter wave type sound generator with a tubular resonator forming a diffuser at the open end thereof.

Abstract: ABSTRACT       A reduction in pressure drops and residual wetness is obtained by fitting a preseparator (3) in the pipe (31) downstream of a high-pressure turbine (1).  The pipe (31) has an internal pipe (33) which constricts the cross-section.  On the upstream side between the start of the internal pipe (33) and the pipe (31), there is an annular gap (32) of isokinetic size, through which the water/ transport steam fixture flows which, further downstream, is calmed by the internal pipe (33) in the form of a Laval nozzle (33a).  The internal phase separation (water/ transport steam) of the mixture is accomplished by a second internal pipe (34).  The water flows through the chamber (35b) and out via the port (37); the transport steam collects in chamber (35a) and is then extracted via the port (36).

Abstract: GAS TURBINE ENGINE                  ABSTRACT OF THE DISCLOSURE          A  gas  turbine engine that can operate at a very high  efficiency over a wide range of load conditions.  In one  important  feature of the invention, combustion gases are  discharged  along two paths, one with constant energy and  the  other with energy that varies in accordance with the  engine  load.  The constant energy discharge drives a turbine  that,  in  turn,  operates  a  compressor for the engine  at  a  constant,  high efficiency.  Alternatively, the  compressor is driven at a speed that varies inversely with  the  engine load such that the engine operates at a high  efficiency  for  all loads.  In another, independent feature  of  the  invention,  the  combustion  occurs at a stoichiometric  ratio  of  fuel  and air, with the turbine blades   being   protected   from   the  vastly  increased combustion  gas  temperatures  by  an  internal  array  of passageways  through  which  cooling  liquid, e.g., liquid fuel,  and  air  are  channeled.    The  fuel  and air mix together  to  form  a rich, turbulent pre-mix for ejection directly  into  the  surrounding combustion chamber.  This configuration  can  also  be utilized to inject steam into the  combustion  chamber, to provide a Rankine cycle, with internal  cogeneration.  In yet another independent aspect of  the invention, the compressor that supplies compressed air    to    the    combustion    chamber   includes   two counter-rotating   radial   impellers,   with  the  second impeller  further  functioning as a diffuser for the first impeller.

Abstract: TOP IMAGED PLASMA DEVELOPABLE RESISTS                        Abstract The present invention is concerned with a method of  converting  the upper  portion  of  a  layer  of polymeric  resist  into  a  dry  etch  resistant  form. Oxygen plasma can then be used to develop the entire resist structure.  The layer of polymeric resist is exposed to patterned radiation which creates labile and reactive hydrogens within the resist by molecular rearrangement.   The  reactive  hydrogens  within  the upper portion of the layer are subsequently reacted with a silylating reagent to form a dry etch resistant compound.   When  the  polymeric  resist  material  is highly  absorbent  of  the  radiation,  the  reactive hydrogens are created only in the upper portion of the layer;  when  the  polymeric  resist material  is more transparent, the formation of the dry etch resistant upper portion must  be controlled via the degree of penetration of the silylating reagent into the layer.

Abstract: ABSTRACT                   Carbonated beverages in bottles lose their carbonation and become flat once the bottle is opened.  In this invention carbonation is preserved and maintained in a simple, inexpensive manner by re-introducing pressure into a bottle which has been opened.  A small pump consisting of a cylinder, piston and threaded cap is attached to the top of an opened bottle.  This hand operated pump re-introduces pressure to the bottle in the form of compressed air and thus maintains the concentration of carbon dioxide in the liquid regardless of the amount of liquid remaining in the bottle.  The pump introduces an air pressure of fifty to sixty pounds per square inch to the bottle which is equivalent to the air pressure found in unopened carbonated beverage bottles at 21 degrees celsius.
