Abstract: A method and apparatus capable of detecting the occurrence of misfiring in an internal combustion engine with high reliability over a wide engine operation range with a simplified structure. Starting from a fact that an engine acceleration changes in dependence upon combustion states in the engine cylinders, a ratio between two periods before and after a predetermined crank angle reference position is successively determined. An angular acceleration of the crankshaft is then determined on the basis of a difference between a current ratio and a preceding ratio for each cylinder. Subsequently, a change in the crankshaft acceleration is determined for comparison with a predetermined value at every ignition timing for each cylinder. If the change exceeds the predetermined value, it is determined the occurrence of misfiring. The method can be carried out by making use of only an output signal of a crank angle sensor which is usually utilized for ignition timing control of the engine.

Abstract: A pressure indication device comprises a housing including a bore in which is received a slidable piston. The piston has two end faces, one of which is for connection to a source of fluid at higher pressure and the other of which is for connection to a source of fluid at lower pressure. The device produces an indication when the pressure differential reaches a predetermined value.

A portion of a test strip of heat sealable material is lapped and a segment of this portion heat sealed together. Upon completion of the heat seal the unsealed ends of the test strip are pulled apart at a prescribed constant rate to gradually delaminate the heat seal while the heat seal is cooled at a prescribed rate.

In the apparatus a threading bar intercepts the strip intermediate its ends and pulls a portion through the opening between opposed dies of a heat sealer and in doing so laps the portion of the strip pulled through the opening.

Abstract: Apparatus and accompanying methods for inclusion in a Coriolis meter that substantially eliminate temperature induced measurement errors which might otherwise be produced by performance differences existing between the separate input channels contained in the meter. Specifically, two pairs of input channels are used in the meter.

While one channel pair is measuring actual flow, the other channel pair is measuring its internal phase delay, with the channels being continuously cycled between these functions.
