Abstract: A value approximately corresponding to the amount of a change in mean effective pressure calculated on the basis of the revolution period of an engine is used for discrimination of a misfire. In detecting a misfired cylinder by comparing this misfire discriminating value with a slice level, while a misfire detection during a coasting time is inihibited. Further, a misfire discriminating value corresponding to a misfired cylinder is verified on the basis of a predetermined varying pattern of the discriminating value. Further the slice level is set to the proper value in accordance with this discriminating value.

Abstract: A stabilizer compound for synthetic resinous materials is a tri-substituted triazine in which each substituent is a N⁴-methylated 2-keto-1,4-diazacyclohexane connected to the triazine ring through an alkylene bridge. This bridge permits efficient methylation of the N⁴ atom in every substituent under conditions which yield crystals having at least 90% purity. These crystals may be further purified to at least 95% purity at which purity level they contain less than 500 ppm ash. The stabilization effect of 95% pure compound in a polyacetal is such that, even with an ash content of 50 ppm, it has better stabilization properties than its 99.2% pure precursor (the non-methylated tri-substituted triazine) with an ash content of 10 ppm, as evidenced by lower formaldehyde evolved and better color retention, that is, developing less color in a water white sample after testing at 259°C.

Abstract: An x-ray film cassette (20) is disclosed which includes a window (22) for allowing imaging of patient identification data onto a film in the cassette by light. The window includes a slidable member (40) made from a single piece (42) of plastics material folded onto itself to form two leaves. The two leaves are secured to one another except in a region adjacent the free end of one of the leaves. One of the leaves is stiff and the other is resiliently flexible. The stiff leaf faces outwardly of the cassette and has an aperture (58) in a region overlying the unsecured region of the flexible leaf to allow a probe (53) to deflect the unsecured region of the flexible leaf. The free end of the flexible leaf has catch means (80) which cooperate with other catch means (82) to prevent movement of the slidable member away from the closed position when the free end region of the second leaf is in the non-deflected condition. The catch means and the other catch means are disengaged from one another when the free end region of the flexible leaf has been deflected by a probe, thereby allowing the slidable member to move to the open position.

Abstract: This invention permits an optimising compiler to select optimal instruction sequences for handling the source level multi-way branch, commonly known as the case or switch statement. A costing heuristic is established, based on machine specific information, which weights the relative performance of instruction sequences used to perform statement selection from several available selection methods. The constants, which form the basis of the selection criteria, are then clustered into sets. This clustering is controlled by the costing heuristic. The resulting sets represent clusters of values for which a particular selection method is most appropriate. The invention is preferably implemented at the intermediate code level, and with appropriate preselection of parameters by the compiler builder, allows the invention to be used on any type of target machine. The use of the invention results in faster compilation and execution.
