Abstract: This invention relates to a method and a device for controlling the cooling of internal combustion engines in order to reduce the corrosive wear of cylinder barrels and piston rings. The corrosion substantially is caused by the sulphur content of the fuel. In a Diesel engine the combustion of the fuel always takes place at a relatively great air excess, which implies that the formation of sulphur trioxide exceeds the formation of sulphur dioxide. Together with the water vapor in the flue gases, in addition to sulphurous acid the stronger sulphuric acid is formed. The corrosion in combination with the wear result in a much too short life of the cylinder liners and piston rings and constitute a significant economic problem. Known tests show for the corrosion of steel in flue gas with 0,01 and 0,02% SO.sub.3 -content a very distinctive maximum at about 150.degree. C., but corrosion minima on both sides of said maximum.

Abstract: The invention relates to a method and apparatus for controlling the braking action of a diesel engine having several cylinders. Hereby valves of the cylinders are opened and closed for supplying compressed air and/or venting the cylinder during a certain moment of the compression stroke. This is accomplished by a transmitter which produces an electric pulse that is transformed into an electro-magnetic force, which controls a valve of a pressurized pilot air system for opening the valve of the particular cylinder.

Abstract: The present invention relates to a process for the preparation of hydrolyzed products from whole grain, and such derived products. The invention solves the problem of obtaining a protein and sugar containing product able to be filtrated whereby this is achieved by treating whole grain, as wheat, maize, rye, barley, oat, and rice, with a proteolytic enzyme to transform waterinsoluble proteins into watersoluble products, and further to treat the starch contents with an amylase free from other carbohydrate hydrolyzing enzymes to form watersoluble starch products, as mono and disaccharides, removing the bran fraction and removing water to obtain a dry, semimoist, or liquid but concentrated derived product. The product is to be added as a sweetening agent in food products as bread, drinks, and cereal products, whereby the bran obtained can be used in bread as fiber additive.
