Abstract: A simplified, low cost absorption heat pump includes a single pressure vessel having first and second insulated compartments in unrestricted fluid communication with one another and containing, hermetically sealed, a working medium. A heat transfer ar is used to maintain the compartments at differential temperatures, but equal pressures so that the absorption cycle proceeds in a two-stage, batch mode, namely boiling of the working medium in the first compartment and simultaneous condensing in the second compartment during the first stage and evaporating in the second compartment and simultaneous absorbing in the first compartment during the second stage. The heat transfer arrangement then utilizes the heat given off or taken in during the absorption cycle for heating/air conditioning in a conventional manner.

Abstract: Apparatus for pickling metal sheet as it moves along a generally flat horizontal path, comprises elongated shallow and sequentially arranged electrolytic pickling and mixed acid pickling tanks each having input and output ends and through which metal sheet to be pickled is continuously fed along a linear, flat path through the use of support rolls underlying the metal sheet at spaced locations between the input and output ends of the tanks. Pickling liquid is maintained in each of the tanks at a given level above the support rolls, whereby the sheet material is immersed in the pickling liquid between the input and output ends of the corresponding tank. Each tank has guide rolls at the input and output ends thereof for guiding the sheet material therethrough, and the support rolls are driven at the speed of the sheet material to minimize the tension on the sheet as it is being pickled.

The microwave susceptor component can include one element which is either directly on or supported above the dough. The susceptor component also includes a susceptor sheet on which the pizza rests.

Abstract: A cartridge valve assembly is slidably and sealingly receivable in a recess therefor in the housing of a pressure regulator for supplied air breathing apparatus. The cartridge valve is preassembled and slidably inserted as a unit in the pressure regulator housing recess, and the body is provided with an external shoulder engaged by a headed fastener in the housing to retain the cartridge valve assembly in the housing recess. The cartridge comprises a cylindrical body having a bore therethrough in which a valve stem is slidably supported for a valve element thereon to open and close the bore at one end thereof providing an air outlet for the valve. An air inlet port opens radially through the body into the bore, and the outer surface of the body carries O-ring seals on axially opposite sides of the air inlet port which sealingly engage the cartridge recess. The end of the body opposite the air inlet pivotally supports a valve stem actuating lever arm.

Abstract: An industrial gas burner is disclosed which operates at low air/fuel ratios to avoid NO.sub.x formation without carbon sooting. The burner includes a refractory block having a cylindrically stepped throat passage extending therethrough, a housing adjacent the inlet end of the refractory block and a swirl plate inbetween the block and housing. Vane passages in the swirl plate provide fluid communication between the throat passage and an annular entrainment passage in the housing. A plurality of circumferentially spaced gas jet nozzles in the entrainment passage cause jet entrainment and mixing of fuel and combustion air which is ported to the entrainment chamber. The jet streams of mixed air/fuel impinge the swirl plate whereat the mixture undergoes a further mixing because of the pressure drop and swirling therein. The swirling air/fuel mixture is thus intimately and thoroughly mixed when it exits the swirl plate as a swirling mass at the entry end of the throat passage where it is ignited.

The wall section is rigidized by a single protrusion in the form of a groove to prevent vertical collapse of the container. The design disclosed permits easy modification of the container for serially stacking thereof.

Abstract: An improved industrial furnace employing a new and unique heat transfer arrangement is disclosed. The furnace is a closed end cylindrical chamber with a circular, concentrically positioned plate dividing one side of the furnace into a fan chamber containing a fan and the other side of the furnace into a heat treat chamber containing the work. The plate has a central under-pressure opening and its outer circular edge is spaced from the cylindrical wall to define an annular space which is non-orificing. Fan rotation in the fan chamber produces an annulus of wind mass swirling at high circumferential speed which axially travels through the non-orificing space towards the closed end of the heat treat chamber at slow speed. Heating elements extend through the non-orificing space into the heat transfer chamber and are constantly impinged by the swirling annulus wind mass to effect good heat transfer therewith.
