Abstract: ROTARY GRATE                 ABSTRACT OF THE DISCLOSURE    An assembly of coaxial rotor units which form part of a grate in an industrial furnace and serve to trans-port as well as to admit air to solid fuel in uncombusted and/or at least partially combusted state.  Each rotor unit has a shell which is assembled of heat-resistant fuel-contacting rings and has gaps for discharge of air into fuel, a hollow core which is received in and rotates with the shell and whose cylindrical wall has apertures for admission of air into compartments disposed between the shell and the core and communicating with the gaps between the rings.  The end walls of the core rotate with or relative to trunnions at least one of which admits air into the core so that such air flows through the apertures of the cylindrical wall, into the compartments. and issues via gaps to contact the fuel.  The core can receive a cylindrical drum which has a peripheral helix or discrete distancing projections and serves to regulate the flow of air along the inner surface of the cylindrical wall so that the cooling of core is more pronounced in regions which are nearer to fuel.  The rings of the shell are assembled of heat-resistant segments which are fastened to the cylindrical wall of the core.

Abstract: A B S T R A C T            An individual thermostat unit for the valve housing of a central heating radiator replaces the conventional radiator valve mechanism and affords a simplified mounting without the need for modifications of pipe connections. This thermostat unit comprises two setting means, one for basic settings, and another for temperature settings. A setting knob gives different tempera-ture settings by being turned on a thread. This same thread per-mits the setting knob to be screwed off as part of the housing of the unit, to make the basic setting means accessible when mounting the unit in a valve housing.

Abstract: ABSTRACT OF THE DISCLOSURE         An apparatus is presented which simulates the circulation system through which a fluid is circulated in an oil well.  The apparatus includes manually adjustable control means which simulate the circulation system controls used in the circulation of fluid through the oil well.  The controls are interfaced with, and drive a digital programmable calculator which calculates the pressure and volume of fluid at a plurality of points in the oil well.  The calculator in turn is interfaced with display means which simulate the circulation system instrumentation during the simulated circulation process.  The apparatus additionally includes means for calculating a formation pressure which is randomly higher than the fluid pressure at the depth of the formation.          Responsive to this increased formation pressure, the apparatus simulates the invasion of formation fluid into the well bore and simulates the reaction of the circulation system as the formation fluid is circulated to the surface.  If the formation fluid is gas, the apparatus simulates the expansion of the gas as it is circulated to the surface.  The apparatus further includes means for automatically, randomly changing a characteristic of the circulation system such as when a failure occurs at a point in the circulation system, thus simulating the action of the circula-tion system during such a failure.  A time multiplier means is included to compress the time required to effect circulation of the fluid in the oil well.  Audio means are provided to simulate the sound of the fluid pump, gas escaping from the circulation system, and to sound an error alarm in the event a pressure limit of the circulation system has been exceeded, or a lowout condition exists.  An apparatus results which is parti-cularly useful in training oil well personnel in the circula-tion of a fluid in an oil well, control of an oil well during drilling, circulating out a kick of formation fluid while pre-venting a blowout, and in recognizing a failure of a component of the circulation system during circulation of a drilling fluid.
