Title: Automatic control of fuel supply for an internal combustion engine equipped with a supercharger
Inventor: HASEGAWA SHUMPEI
IPC: F02D23/02
Filed: 1983-05-24
Abstract: A method for electronically controlling the fuel supply to an internal combustion engine 1 equipped with a supercharger 7 has first and second pressure sensors 9', 9, downstream of a throttle valve 3a. A plurality of predetermined values of basic fuel quantity are stored in each of first and second storage means corresponding, respectively, to the first and second pressure sensors, as functions of the intake passage pressure and the engine speed. The first pressure sensor 9' covers a lower range of pressures than the second pressure sensor 9. When the sensed pressure is lower than a predetermined value, a stored value of basic fuel quantity is read from the first storage means, and when the sensed pressure is higher than the predetermined value, a stored value of basic fuel quantity is read from the second storage means.The quantity of fuel corresponding to the stored value is supplied to the engine by injectors 6a, 6b. If the output signal from the first pressure sensor indicates a higher pressure but the output signal from the second pressure sensor indicates a lower pressure than the predetermined value, then there is an abnormality in the second pressure sensor and the fuel is cut off. <IMAGE>

Title: An autogenous grinding method
Inventor: MARKLUND OLLE EMANUEL
IPC: B02C21/00
Filed: 1982-11-22
Abstract: The present invention relates to a method for comminuting a coarse lump mineral material in an autogenous primary grinding system, in which an ingoing material is divided into a coarse fraction and a fine fraction is determined by a crushing point determined by the point of intersection between two tangents drawn through two adjacent inflexion points on a size distribution graph obtained by screen analysis of a grinding mill charge of material obtained after an autogenous grinding process. The smallest particle size of the coarse fraction is greater than the particle sizes in the upper of said inflexion points, and the ratio between said fractions is determined on the basis of achieving a given charge quantity for a particular, selected set-point power value fo the mill in question, and determined with respect to a selected degree of grinding.The grinding efficiency of autogenous primary grinding mills is greatly improved by means of the invention (Figure 4).

Title: Determination of hydrocarbons in rock samples
Inventor: MARTIN STEPHEN J
IPC: G01N31/12
Filed: 1984-07-02
Abstract: A method of determining quantitatively and qualitatively the hydrocarbons present in a sample in which the sample is pyrolyzed, the off stream split into two with one stream analyzed for total hydrocarbons present and the other stream passed through traps to separate the oil range hydrocarbons from the gas range hydrocarbons.
