Patent FI-20085263-A (FI)
Inventor: PORTIN KAJ
IPC: F02D41/00
Filed: 2008-03-31
Abstract: The invention relates to supplying pilot fuel to the cylinders of a combustion engine. The invention comprises cylinder-specific pressure sensors (1) that are installed in the cylinders of the combustion engine, as well as a control unit (2). The control unit determines each cylinder's crankshaft angle at maximum pressure and the cylinders' average crankshaft angle at maximum pressure, and verifies whether the average crankshaft angle at maximum pressure is within a certain range of crankshaft angle variation. If the average crankshaft angle at maximum pressure is outside the range of variation, the duration of total pilot fuel injection into the engine is controlled. Furthermore, the differences between each cylinder's crankshaft angle at maximum pressure and the average crankshaft angle at maximum pressure are determined. The differences are compared with a certain range of difference variation, and the duration of fuel injection into a cylinder is controlled if the difference in an individual cylinder traverses the minimum or maximum limit of the range of difference variation.

Abstract: In the manufacture of regenerated cellulose fibres having a high shrinkage potential, e.g. 20-30% when immersed in boiling water with elongation at break of about 20% (wet), viscose is spun at a speed of 70-120 metres per minute through a tube immersed in a spinning bath and coaxial with the spinneret, the acidity of the bath being 120-125 grms. of sulphuric acid per litre, sodium and zinc sulphate contents 230-250 and 125-130 grms. per litre, the salt point being above 7% and the viscose being heated to the temperature of the bath immediately on the upstream side of the spinneret, and the filaments are dried under a tension sufficient to prevent shrinkage.  These filaments (then having elongation at break of about 45%) are wet stretched, e.g. in a dilute aqueous bath at 85 DEG  C., in one or more stages to a degree close to their elongation at break, e.g. 60-70% thereof or 30% of their original length, before or after the drying operation.  On leaving the spinneret, the filaments are drawn up to 25%.  The viscose or the bath may contain one or more components e.g. thiodiglycol and polyhydroxyethylenes, which promote formation of thick-skinned filaments.  The filaments may be stapled by cutting or stretching to break, e.g. by the process described in Specification 774,360, [Group IX], and the filaments or staple fibre may be blended with filaments or fibres having high tenacity, low elongation and high resistance to shrinking under the action of hot water, e.g. cellulose acetate fibres or viscose fibres obtained by the process described in Specification 650,896, and spun into yarn. Bundles of the two forms of filaments may be formed into a blended yarn which is drafted to break the filaments into staple lengths within the yarn.  The composite yarn is bulked by subsequent subjection of yarn or fabric made therefrom to the shrinking action (on one yarn constituent) of a hot aqueous medium which may be combined with dyeing and followed by treatment with 5% of a ureaformaldehyde resin to render the fabric crease-and shrink-proof to washing.  Specifications 655,516 and 778,746 also are referred to.

Abstract: 1289293 Automatic control of speed BRITISH DOMESTIC APPLIANCES Ltd 29 Sept 1969 [30 Sept 1968] 46326/68 Heading G3R [Also in Division H2] In a washing machine, the current in motor 1 is controlled by controlling the firing angle of thyristor 2 by means of a firing pulse control circuit comprising a complementary pair of transistors 13, 14. The motor current is also monitored by resistor 3, the resulting voltage being used to control the firing pulses to thyristor 2 and hence the maximum motor current. As described, a low voltage DC supply is developed across Zener diode 17 by rectification at 40 of the AC supply. Capacitor 12 is charged during each positive half cycle via diode 45, the rate of charge being determined by transistor 19 in dependance upon a speed control voltage at terminals 5, 6 e.g. from a tachogenerator or manual potentiometer. When capacitor 12 is sufficiently charged to turn on complementary transistors 13, 14, diode 45 becomes non-conductive so that capacitor 12 is discharged through the gate circuit of thyristor 2, initiating one pulse in the motor 1. Transistor 36 is normally held conductive by the potential divider 37, 38, but in the event of excessive motor current the voltage across resistor 3 would turn off transistor 36, turning on diode 39 which bypasses the control voltage at terminals 5, 6 and thus delays or eliminates the firing pulses for thyristor 2. Back-to-back thyristors may be employed.
