Birds are moved through chilled water by bird moving means such as an auger or by a series of paddles. The birds tend to accumulate in a predetermined path in the water. Streams of water that include an antibacterial additive are directed toward the predetermined path and engage and disperse the birds, and wash the birds with the streams of water and the antibacterial additive, thereby increasing the rate of heat transfer from the birds and increasing the effectiveness of the antibacterial properties of the agents in the chilled water.

A method for operating a vehicle to reduce exhaust emissions is provided. The vehicle includes an engine, a motor, a battery for operating the motor, and a catalyst for reducing exhaust gas emissions. The vehicle is operated in a first mode when at least one predetermined condition is met. The first mode includes providing at least some of the desired vehicle output power with the motor. The engine is operated to quickly increase the temperature of the catalyst when the output power from the battery is within a first predetermined range. When the output power of the battery is outside the first predetermined range, the operation of the engine is adjusted to drive battery operation into the first predetermined range. When the at least one predetermined condition is not met, the vehicle is operated in a second mode based at least partly on driver demand and battery requirements.

The chiller includes a semi-cylindrical tank (36) that conforms to the perimeter of its auger (38) so that the water can be raised to a water level (68) high above the auger shaft (44). Streams of water (84) are directed from the pulling side (80) across the lower portion of the tank beneath the auger shaft (44) to the dead side 82 of the tank at intervals along the tank so as to disperse the lower portion of the masses (23) of buoyant birds (22) from the more crowded pulling side (80) of the tank, beneath the auger shaft (44) toward the more vacant dead side (82) of the tank, thereby distributing the products more evenly throughout the tank and causing more water turbulence in the tank, thereby increasing the rate of heat transfer from the birds and avoiding having the birds cross over the auger shaft moving backward in chiller into a following flight of the auger.

A system and method for controlling an engine in a vehicle to facilitate heat transfer to a passenger compartment is provided. A number of conditions are examined, and if it is found that one or more of these conditions matches a corresponding predetermined condition, the spark timing of the engine is retarded. In addition, a charge motion control valve is opened, thereby increasing the amount, and reducing the turbulence, of the air entering the engine. This facilitates hotter combustion within the engine, and therefore faster heat transfer to the vehicle passenger compartment.

The invention provides a kind of 1E grade K1 cable insulation material for nuclear power, which is prepared by compounding and blending a flame retardant system, a plastic modifier and an anti-radiation additive to meet the requirements of a nuclear power plant. Long-life, radiation-resistant 1E-class K1 cable insulation material, its performance meets the relevant requirements of the IEEE383-2003 standard.

A filament lamp has a bulb comprised of a straight light emitting tube from which a pair of flat hermetically sealed portions extend, a plurality of coiled filaments arranged within the light emitting tube, in the tube axis direction a pair of internal leads are connected to ends of the filament by a respective one of a plurality of metal foils that are embedded in the hermetically sealed portions, and external leads are connected to the metal foils. The width of metal foils embedded in the hermetically sealed portions is increased so as not to cause them to melt even when an electric current to be supplied to the filament lamp is increased, the hermetically sealed portions being made wider than the external diameter of the light emitting tube and the width between outer margins of the metal foils in a direction at right angles of the tube axis is greater than the internal diameter of the light emitting tube.

The invention relates to a single-end electric heating tube structure with the double insulation protection function and a manufacturing method of the single-end electric heating tube structure with the double insulation protection function. The single-end electric heating tube with the double insulation protection function comprises an outer tube and an inner assembly part, wherein the inner assembly part comprises two inner tube assemblies, terminals, an inner sleeve, an outer sleeve, a fuse protector and a temperature controller, each inner tube assembly comprises an inner tube, an upper guide-out rod, a lower guide-out rod, a resistance wire, an inner plug and magnesia powder, the upper guide-out rods, the resistance wires and the lower guide-out rods which are all connected well are inserted in the inner tubes so that the inner tube assemblies can be formed, one terminal is connected with one end of the temperature controller, the other end of the temperature controller is connected with the lower guide-out rod of the second inner tube assembly, a protecting middle piece is sleeved with the outer sleeve, and thus the inner assembly part can be formed. The single-end electric heating tube structure has the double insulation protection function and solves the problem that two resistance wires intertwine, cost is saved, the service life of a heater is prolonged, and the temperature resistance level of the product is increased.

The invention provides a nuclear power 1E-level K3-type thermal shrinkage material and a preparation process. Prepared polyolefin resin, flame retardant, antioxidizer, thermal stabilizer and modifyingagent are led into and mixed in an internal mixer; after polyolefine is melted, plastic processing aid is added, and masterbatch of the 1 E degree K3 thermal shrinkage material can be obtained afterthe operation of mixing is carried out; and after being pressed into pieces by an oil hydraulic press or being extruded by an extruding machine, the masterbatch is irradiated by an electron accelerator so as to obtain the 1E-level K3-type thermal shrinkage material. The coordination effect of nitrogen-containing flame retardant, halogen-free flame retardant aluminium hydroxide and magnesium hydroxide system is utilized to improve the flame retardant property and the temperature-resistance property; and the selected plastic modifying agent, i.e. ethylene propylene terpolymer rubber, silicon rubber, and thermal stabilizer, i.e. methyl tin mercaptide, are respectively conducive to improving temperature grade of the system, thereby meeting the higher requirement of enabling the service life toreach 40 years at the temperature of 90 DEG C under the circumstance that the system keeps other properties at an excellent state.

The invention discloses a combined heat exchange system, and belongs to the technical field of high-temperature heat recovery systems. The combined heat exchange system comprises a shell, one end of the shell is provided with a high-temperature medium inlet, the other end of the shell is provided with a high-temperature medium outlet, a heat exchange pipe bundle is arranged in the shell, a steam pocket communicated with the heat exchange pipe bundle through a pipeline is arranged outside the shell, and the pipeline comprises a descending pipe communicated between the steam pocket and a heat exchange pipe bundle inlet and an ascending pipe communicated between a heat exchange pipe bundle outlet and the steam pocket. When a high-temperature medium flows in the shell, the heat exchange pipe bundle is communicated with the steam pocket to form natural circulation, a cooling medium in the heat exchange pipe bundle takes away a part of heat of the high-temperature medium, so that heat energy of the high-temperature medium is used fully, the flowing distance and the flowing resistance of the high-temperature medium are reduced, and pressure drop losses of the high-temperature medium are also reduced; in addition, due to the fact that the heat exchange pipe bundle is arranged in the shell, the heat exchange pipe bundle can expand freely, and the safety problem of cracking of the heat exchange system is avoided.
