Abstract: A cylinder head cooling structure and an oil temperature control system are provided for an internal combustion engine having a plurality of cylinders, each having a plurality of intake ports and a plurality of exhaust ports. The engine includes cooling oil jackets surrounding the spark plugs in the cylinder head, a thermostat attached to the front surface of the crankcase independently of an oil filter, and an oil temperature sensor disposed on a rear face of the cylinder block above the crankcase in an oil supply path formed on the cylinder rear face for supplying oil to the oil jackets. Oil passages conducting oil into the oil jacket are provided between two separate parts of a bifucated intake port and between two separate parts of a bifurcated exhaust port, and only cooling system oil reaching high temperatures is allowed to flow through the thermostat, thereby improving temperature control response.

Abstract: A pneumatic motor is provided with twin cylinders each with a piston installed therein slidably, disposed horizontally adjacent in a direction parallel to axis of a motor shaft interposed between the twin cylinders and arranged in a direction intersecting with the twin cylinders at a right angle. An association system couples the motor shaft to each piston and is arranged so as to convert a linear movement of each piston into a rotational movement and transmit the rotational movement to the motor shaft. The twin cylinders, the motor shaft and the association system are disposed integrally in a casing. The association system has each of a first eccentric shaft and a second eccentric shaft, which in turn are disposed projecting from the motor shaft in opposite directions at a phase angle of 90 and coupled with a first eccentric pin and a second eccentric pin in an eccentric state, which in turn are coupled in association with the respective pistons.

Abstract: An applying means in a discharge means includes a set of electrodes, and the electrodes face the ground level, are aligned along one continuous plane, are separated from each other at specified intervals in the horizontal direction, and are set to the same electrical potential. When the direct current high voltage is supplied from a power supply means, electric force lines are directed upward in the air above the applying means, producing charged particles based on corona discharge from the applying means. The charged particles absorb water in the air, condensing and binding into water, and dispersing the fog.

Abstract: A winding machine, useful as an air hoist, includes a winding portion about which a chain is wound, and from which articles are hung for loading and/or unloading thereof. The winding machine is rotationally powered by an air driven motor controlled by an air supply valve which regulates the supply of air to the motor by virtue of a built-in variable shuttle valve. An operation unit pneumatically biases a main spool in the shuttle valve in a desired direction and to a selected extent to provide, respectively, rotation in normal and reverse directions, by permitting adjustable flow-through of air from a supply line. A rotation suspending mechanism includes an air activated braking mechanism, normally biased to provide braking of the motor when not actively being rotationally operated. The braking mechanism is connected through a variable aperture to the air supply, such that sufficient air pressure provided thereto overcomes the biasing thereof.

Abstract: The ozone generating and condensing system includes an oxygen generator for isolating oxygen from an air, an ozonizer provided downstream of the oxygen generator for generating ozone from the oxygen, two parallel-connected ozone absorption towers provided downstream of the ozonizer, an ozone absorption switching mechanism for allowing the ozone to flow into one of the absorption towers from the ozonizer and for recirculating to the ozonizer residual oxygen discharged from the one of the ozone absorption towers after an ozone absorption cycle therein, and an ozone release switching mechanism for introducing the nitrogen generated by the oxygen generator as a carrier gas to the one of the absorption towers after completion of ozone absorption cycle to release the absorbed ozone from the one of the ozone absorption towers and further for causing the released ozone to flow into a reactor tower located downstream of the absorption towers.

Abstract: Apparatus and method for manufacturing crushed sands from blast furnace melted slags including maintaining molten blast furnace melted slags out of contact with water while cooling the molten slags to a temperature between 850.degree. C. to 1300.degree. C. and then rapidly cooling the cooled slags with water thereby producing coarse grain hard quality water processed slags.
