System-design considerations for secondary surveillance radar for air-traffic control

Students Quarterly Journal, 1970
After describing the principles of operation and operational uses of a secondary-surveillance-radar system, the author discusses a typical system composition and limitations. Methods of alleviating the system limitations are then described, followed by factors which are considered when specifying the system components.

The Importance of Secondary Air Mixing in Exhaust Thermal Reactor Systems

SAE Technical Paper Series, 1975
<div class="htmlview paragraph">Automotive thermal reactors have obtained high conversion efficiencies on engines with very rich carburetion, but fuel economy and reactor durability have suffered. Improved mixing of exhaust gas and secondary air in the engine exhaust port was examined as a means of improving reactor efficiency at less rich engine

Simulation Results for an Air-Conditioning System With Secondary Refrigerant Loops

Heat Pump and Refrigeration Systems Design, Analysis, and Applications, 1995
Abstract There are some highly efficient and environmentally safe hydrocarbons and HFCs proposed as R22 substitutes, but they are flammable. The use of these refrigerants in an air-conditioning/heat pump system may not be acceptable. The present research looks into the prospects of using an additional loop with a secondary refrigerant as

INTERNAL COMBUSTION ENGINE COMPRISING A SECONDARY AIR INJECTION SYSTEM

2001
The invention relates to an internal combustion engine comprising at least one line system for secondary air. A module body comprises a portion of the lines (25, 30, 35), a portion of the actuating valves (26a, 31, 26b), and check valves (27). The throttle valve (13) and its actuator (36) are additionally integrated in said module.

[Systemic air embolism secondary to respiratory therapy in the newborn].

RoFo : Fortschritte auf dem Gebiete der Rontgenstrahlen und der Nuklearmedizin, 1984
Air embolism are a rare complication of assisted ventilation in the neonatal period. An example is described and the radiological appearances are illustrated. Possible means by which air could enter the vascular system are discussed.

Secondary Air Systems: Gaz Türbinlerinde Görünmeyen Bir Temel Yapı

Modern gaz türbinli motorlar, yalnızca itki üretmek için değil, aynı zamanda yüksek sıcaklık, yüksek basınç ve dinamik yükler altında güvenilir çalışmak üzere tasarlanır. Bu koşullarda motorun yalnızca ana akış (primary flow) ile yönetilmesi mümkün değildir.
