Sound suppressor for a firearm


A sound suppressor for a firearm with a high rate of fire, such as a machine gun, conceals the location of the firearm during heavy use by rapidly dissipating heat through a foamed carbon core. A sound suppressing baffle core is coaxially located within a tubular housing, having flared ends extending beyond the core.

Air-conditioning system


In an air-conditioning system, during precooling or preheating control, a setting temperature is controlled such that a first temperature difference between the setting temperature and an indoor temperature is not less than a temperature difference at which a compressor performs operation, and the setting temperature is controlled to be changed to a target temperature when a second temperature difference between the indoor temperature and the target temperature is less than the first temperature difference. Since the compressor can be operated in the range from a low capacity to a medium capacity, operation efficiency of the air-conditioning apparatus can be increased, and the energy-saving operation with less power consumption can be realized.

Control strategy for engine-operated compressor


An engine controller causes a propulsion engine of a motor vehicle to be fueled in a fueling mode of operation and not to be fueled in a non-fueling mode of operation. A controlled device, such as a clutch or regulator, controls operation of a pneumatic compressor which forces compressed air into a storage tank.

Isothermal compression based combustion engine


Systems and methods are disclosed that include operating an isothermal compression based combustion (isoc) engine by injecting isothermally compressed air into a combustion engine immediately prior to a combustion event in order to increase the efficiency of the engine, improve emissions, and substantially eliminate autoignition and associated design constraints. The isoc engine utilizes an intercooled compressor to isothermally compress air that is stored in a plurality of capacitance tanks prior to delivery of the compressed air to the combustion engine.
