Abstract: A system for operating a two-cycle spark ignition engine, comprising an ultrasonic atomizer that is disposed in an intake pipe of the spark ignition engine. When the engine is to be started, a fuel for starting is supplied to the ultrasonic atomizer, and after the engine has been started, a gas oil is supplied to the ultrasonic atomizer to atomize and spray it into the intake pipe, thereby enabling an increase in the flow rate of fuel atomized and sprayed by the ultrasonic atomizer and realizing combustion of gas oil, and thus achieving a lowering in the fuel cost, ensuring safety and making it possible to provide a lightweight emergency pump unit which is suitable for use in vessels, for example.

Abstract: A process for treating waste water containing radioactive substances comprising treating the waste water by reverse osmosis in the presence of at least one organic surfactant selected from the group consisting of anionic surfactants, cationic surfactants and nonionic surfactants.

Abstract: In a ship for transporting cold pellets of iron ore a perforated piping is arranged in the holds of the ship and exhaust gas from the boiler or engine of the ship is ejected into the cold pellets loaded in the holds through the perforations of the piping thus drying and hardening the pellets during the voyage.

Abstract: A container yard is provided with a first container handling machine installed in the transferring area of the yard, a second container handling machine free to move in the yard, a vehicle for transferring the container, a gate located in another transferring area of the yard, and a control center responsive to the input and output information of the containers for commanding and supervising the loading and unloading operations of the first and second machines and of the vehicle in the yard.

Abstract: Apparatus for constructing a block tower for a suspension bridge includes a working platform, means for raising and lowering the platform vertically along a pre-erected base of the tower, and a carriage movable horizontally on tracks on the working platform. The carriage moves between a block loading station lateral of the base and a block unloading station above the top of the tower base where the block is superimposed on other blocks of the pre-erected base. The carriage is specially designed to raise and lower the lower block and to disengage the same at the block unloading station for return to the block loading station. A method is also disclosed for constructing a tower of built-up blocks.

Abstract: Apparatus for coating bottles with resin in order to prevent the explosion thereof characterized in that the bottle is held by a holder at the mouth portion and at its inner wall, so that the bottle may be invisibly coated with resin except for the mouth portion and bottom.

Abstract: A method of disposing of solid or paste-like paint waste in which the paint waste is firmly comminuted and mixed with waste oil and water, preferably with detergent present, to form a low-sedimentation rate slurry, and the slurry then incinerated to provide substantially complete combustion of said paint waste.

Abstract: Rail crossover arrangement characterized in that wheels can pass through the crossover without shock. To this end flanged portions of the wheels are supported on the crossover plate provided in the intersections of the rails when the wheels pass through the intersections.

Abstract: The position of a ship moored by at least three anchor ropes extending between the ship and independent remote anchor points is corrected by a control system comprising a rope orientation angle detector, a device for designating the angle and amount of movement of the ship which are necessary to correct the position of the ship, a position correction parameter designating device which determines whether parallel movement or swinging movement is to be made to correct the position of the ship and sends the result of determination to the rope orientation angle detector, a deviation operator which compares the angle of movement with the rope orientation angle for producing an output corresponding to the differential angle, a rope extension and contraction control device responsive to the outputs from the deviation operator and the rope orientation angle detector for producing an output for commanding paying out or taking up of respective anchor ropes, and winches mounted on the ship for operating respective ancho

Abstract: Vertical tube type cracking furnace in which a convection-heating section for preheating the process fluid is provided above the combustion chamber, and gas passages connecting the convection-heating section and the combustion chamber are symmetrically provided.

Abstract: In a simulator of the class which is operated repeatedly according to the same program there are provided a mini-computer, a time axis controller and a communicating device. The time axis controller provides a pulse to the mini-computer for controlling the timing of the programmed processing operation thereof and is provided with means for manually varying the period of the pulse thereby to vary the timing of the programmed processing operation while observing the content of the display provided by the communicating device.
