Abstract: ABSTRACT OF THE DISCLOSURE          The wall tubes of the combustion chamber of a steam generator extend along the chamber which is divided transversely into at least two burner layers.  Each layer includes at least two burners disposed in a common transverse plane.  The jet axis of the flame from each burner extends tangentially of a circle concentric with the longitudinal axis of the chamber.  All burners are oriented in the same direction of rotation relative to the chamber.  The burners of one layer are offset with respect to those of the other layer in the peripheral direction.  The invention improves the uniformity of the condition of the working medium at the outlet from the combustion chamber.  Another advantage is in its structural simplicity.

Abstract: A CLOSED CENTER, LOAD SENSING HYDRAULIC SYSTEM           Abstract of the Disclosure A closed center, load sensing hydraulic system is disclosed which contains a primary work circuit which has priority in flow demand over a secondary work circuit.  The system includes a variable displacement pump fluidly connected between a reservoir and a control valve with the primary work circuit.  The primary work circuit includes a control valve which regulates fluid flow from the pump to a primary hydraulic function and which includes a feedback mechanism connected thereto.  The secondary work circuit also includes a manually operable control valve for regulating fluid flow from the pump to a secondary hydraulic function.  A priority valve is connected between the pump and the secondary work circuit and movable between an open and a closed position to regulate the pressure of fluid discharged by the pump.  Pressurized fluid from the primary work circuit is conveyed through a load signal line to the priority valve such that the pressurized fluid will urge the priority valve towards a closed position thereby assuring that adequate fluid pressure is available from the pump to the primary work circuit.  The system also includes a control valve for sensing pressure variations between the fluid discharged from the pump and fluid present in the load signal line.  This valve controls fluid flow out of the primary hydraulic function, via the load signal line, when the pressure of the fluid discharged by the pump is less than the pressure of the fluid in the load signal line and thereby essentially eliminates kickback from the primary control valve.

Abstract: ABSTRACT           In  an  air mat apparatus comprising a  mat  body having a plurality of defined air chamber,  there is an air source  for feeding air to each of the air chambers of  the mat  body and a changeover valve connected between the  mat body  and the air source for controlling the air feed  from the air source to each of air chambers.   An air-containing elastic  layer has such an elasticity and is provided  with numerous voids which can suck air into the inside and which are  open  to  the outside air so that  the  air-containing elastic  layer is made to discharge such air when  the  air chambers  are  inflated  and deflated whereby a  compulsory ventilation  is achieved between the mat body and the  body surface  of the user.   The present invention relates to an air mat apparatus which is mainly laid on a bed or chair or wound  round  a hand or leg in order to promote  the  blood circulation of the body surface,  to prevent bedsores or to massage the waist, back, hand, leg or the like.

Abstract: SOLVENT ASSISTED STEAM INJECTION PROCESS      FOR RECOVERY OF VISCOUS OIL                           ABSTRACT          A method for recovery of viscous oil from a subterranean, viscous oil-containing formation employing a mixture of steam and solvent in specific amounts and specific solvent equilibrium K-values at initial formation temperature and pressure to attain maximum solvent efficiency based upon the ratio of cumulative oil recovered to the amount of solvent injected and unrecovered at steam breakthrough.  For a light solvent, maximum solvent efficiency is obtained by injecting a mixture of steam and 2 to 5 volume % solvent having an equilibrium K-value of at least .5 into the formation.  Suitable light solvents include C1 to C4 hydrocarbons and carbon dioxide.  For a medium solvent, maximum solvent efficiency is obtained using a mixture of steam and 5 to 10 volume % solvent having an equilibrium K-value within the range of .005 to .5.          Suitable medium solvents include C5 to C9 hydrocarbons, naphtha and natural gasoline.  For a medium heavy solvent, maximum oil recovery is obtained using a mixture of steam and at least 10 volume %, and preferably 10 to 15 volume % solvent having an equiliorium K-value within the range of .00005 to .005.  Suitable medium heavy solvents include C10 to C14 hydrocarbons, light crude and syncrude.  The mixture of steam and solvent is injected into the lower 50% or less of the formation via an injection well and fluids including oil and a portion of the solvent are produced from the upper 50% or more of the formation via a spaced-apart production well.  The amount of steam injected is 0.30 to 0.50 pure volume at a temperature of 500°F to 700°F, a quality of 50 to 90%, and an injection rate of 4 to 7 barrels (CWE) per day per acre-foot of formation.  Thereafter, production of fluids including oil and light solvent is continued until steam breakthrough occurs or until the fluid being produced contains a predetermined amount of water, preferably at least 95%.  The method is applied to a viscous oil-containing formation in which either naturally occurring or induced communication exists between the injection well and the production well in the bottom zone of the formation.  In another embodiment of the invention, injection of the mixture of steam and solvent may be continued and fluids including oil and solvent are produced until steam breakthrough occurs or until the water cut of the produced fluid contains at least 95% water.

Abstract: ABSTRACT OF THE DISCLOSURE The invention provides an acousto-optic tunable filter configuration and a method for the operation of such an  apparatus  in  which  the  tuning  range  is  extended. According  to  the  new  configuration,   a  non-collinear acousto-optic tunable filter crystal has a first transducer bonded to one transducer face of the crystal and a single transducer  bonded  on  the  opposite  crystal  face  which crystal  face  is  cut so as to be parallel to the first transducer.  The  first  transducer  is  fabricated  to  the proper thickness to operate at a center frequency f1 and the second transducer is fabricated so as to operate at a center frequency f2.  The method of extending the tuning range of the acousto-optic tunable  filter comprises the steps  of:   introducing  incident  light  into the acousto-optic  tunable  filter  which  filter  comprises  a  crystal having an optical input face,  an optical output face and first and second parallel sides.  Launching acoustic waves having a center  frequency f1 into the crystal from the crystal's first side. These acoustic waves propagate in a first direction such that the interaction of the acoustic wave with the light results in the absorption of a phonon. Acoustic waves having a center frequency f2 are launched into the  crystal  from  the crystal's  second  side.   The acoustic waves  of  a center frequency f2 propagate in a second  direction  which  is  anti-parallel  to  the  first direction such that the interaction with the light by the second series of acoustic waves results in the stimulated emission of a phonon.
