摘要:
A variable valve timing mechanism for an internal combustion engine wherein the camshaft is supported at one end by a combined bearing and valve body member that is detachably connected to the supporting engine body. The connection is such that fluid from the engine lubricating system can be delivered to this body and distributed by control valves mounted in it. This simplifies machining of the engine body and permits a more compact, lower cost construction without sacrificing any function.

An induction system and control arrangement for a three valve per cylinder engine, wherein the induction passages are tuned to provide different effective lengths for different engine running conditions. In addition, a control valve arrangement is provided for controlling the flow to the combustion chambers through the valve seats to generate unrestricted flow under high-speed, high-load conditions and tumble and/or tumble and swirl for promoting turbulence under low-speed, low-load conditions.

A roller mill according to this invention includes a base and a table supported on the base, the table being adapted to be rotated on a generally vertical axis. The table has an annular groove formed in its top surface, the groove having a semicircular cross section. At least one roller is supported by the base above the table, each roller being rotatable on an axis which intersects with the vertical axis of the table. Each roller has an arcuate peripheral portion which forms part of a circle of curvature in cross section. The roller and the table rotate on their respective axes, and they are adapted to compress and mill material in the groove betweem them, a clearance which receives the material being formed between the peripheral portion of the roller and the groove. The roller has a wider axial dimension on the side which is inward radially of the table from a radial plane of the roller, this plane passing through the center of the circle of the peripheral part of the roller, than the axial dimension on the outward side of the table.
摘要:
A calcining system wherein raw material is preheated by raw material preheating device for preheating the raw material by contact with a gas, calcined in a rotary kiln and cooled in a planetary cooler; a portion of cooling gas used for cooling the calcined material in the planetary cooler and heated thereby is led through an air extracting duct to the raw material preheating device and the rest of the heated cooling gas is introduced into the rotary kiln: and exhaust gases from the rotary kiln is led to the raw material preheating device. Such calcining system further includes a first damper mounted in a duct for discharging the exhaust gas from the raw material preheating device, a temperature sensor for sensing the temperature of calcined material discharged through an outlet of the planetary cooler, control device for controlling the degree of opening of the first damper when the temperature sensed by the temperature sensor rises to a high level, a second damper mounted in the air extracting duct, a gas sensor for sensing a gas component capable of indicating the condition of combustion in the rotary kiln, and control device for controlling the degree of opening of the second damper so as to bring the value of the gas component sensed by the gas sensor to a predetermined level. The flow rate of the cooling air can be controlled independently of the control of the flow rate of the air combustion, so that the temperature of the calcined material at the outlet of the planetary cooler can be kept at a predetermined level selected arbitrarily and the combustion in the rotary kiln and the calciner can be stabilized irrespective of changes in the conditions of operation.
