Abstract: An infrared radiation heater includes: a combustion chamber having a combustion space that is open on one side; a combustion device provided in the combustion chamber to combust air-fuel mixture made by mixing fuel with air; and a radiator configured to be heated by heat generated from the combustion device and including a radiation plane configured to emit infrared radiation. The combustion device includes: a nozzle provided in a flow path of the air to inject the fuel; a tubular body including a side surface that faces a direction with a predetermined angle with respect to the radiation plane, and a plurality of voids being formed on the side surface; and an ignition device provided outside of the tubular body and configured to ignite the air-fuel mixture. The air-fuel mixture flows into the tubular body, and the tubular body releases the air-fuel mixture from the voids into the combustion chamber.

Abstract: The present invention comprises an assembly patio heater (PH) base at the bottom, a gas combination valve, a reducing bushing unit, a PH perforated cylinder, a tubing unit along with the pilot assembly, PH pan head, a gas combination control assembly, a gas lighter unit, a burner assembly and an assembly PH emitter grid assembly. A reflector is mounted at the top of the assembly PH emitter grid assembly. The present invention provides an automatic ignition system along with ON/OFF switch and the device also has an inbuilt transformer which provides the safety to the user(s). Hence, the present invention is very easy to operate and user friendly.

Abstract: The number of piglets dying at birth is reduced by providing a temperature sensor in a farrowing crate at the piglet area thereof on a movable cover so that, when the sow is expected to give birth, the sensor is located in the crate at a location to detect the presence of one or more piglets after birth. On detection by a control unit using the sensor signal of the one or more piglets, the sensor communicates a signal to a pager carried by an operator indicating to the operator that birth of piglets is in progress and activates a heating lamp for the piglets in the pen to attract them away from the area of the sow to reduce crushing. The control unit and the sensor also control the heat output. The cover can slide along the piglet area and can lift to expose the piglet area.

Abstract: A gas burner assembly for a brooding house has a gas burner which is fabricated from a precision steel stamping process. The gas burner has a venturi tube which extends between an orifice fitting and a burner head. The burner head is manufactured from an upper and a lower burner head. Each upper and lower burner head defines a plurality of burner ports with the ports of the lower burner head being in registry with the ports in the upper burner head to define the ports in the upper burner head to define the ports for the gas burner. The upper and lower burner heads are mechanically connected by a series of tabs and slots formed on the upper and lower burner head.

Abstract: A gas burner assembly for a poultry house heater having a head that is fabricated from a metal stamping process. The gas burner has a venturi tube which extends between a burner orifice and a burner head. The burner head is manufactured from a top plate and a bottom plate. The top and bottom plates define about forty upper half and lower half burner ports wherein the lower half ports of the bottom plate are in registry with the upper half ports in the top plate to define the ports for the gas burner. The interior of the head is shaped to form a chamber around the junction with the venturi tube having a height greater than said ports, and the interior surface of the head is smooth and free of sharp edges. The top and bottom plates are mechanically connected by a series of tabs and slots formed on the top and bottom plates.
