Abstract: A method and a system (2) for gas stunning animals for slaughter is described, where the animals arrive at the poultry slaughterhouse in transport crates (6), where gas stunning of the animals is effected while they are still in transport crates (6), and where the transport crates with the animals, by means of a number of conveyors (12, 14, 18, 20), are conveyed successively through a stunning chamber (8), where the action of the gas for stunning of the animals is adjusted by shortening or prolonging the conveying time and/or the conveying route of the said transport crates (6) through the stunning chamber (8). It has surprisingly appeared that by means of such simple measures it is possible to optimize stunning while at the same time considering all the parameters. If the stunning condition of the animals is not optimum, it is easy to prolong or shorten the conveying time and/or the conveying route through the stunning chamber.

Abstract: Method for finding the angular acceleration of a drive shaft of an internal combustion engine by means of a gear wheel integral with said drive shaft; the method making provision to identify, in each complete revolution of the drive shaft, a number of angular measurement lines, to measure the time used by the drive shaft to pass over each angular measurement line using the signal supplied by the gear wheel, to add algebraically, to the time used by the drive shaft to pass over each angular measurement line, a corresponding correction coefficient that takes account of any asymmetries in the gear wheel, and to determine the value of angular acceleration of the drive shaft as a function of the time used by the drive shaft to pass over each angular measurement line; the value of the correction coefficients is determined in the course of an engine fuel cut-off phase.

Abstract: A unit for transporting live poultry includes a supporting frame and a series of drawer-type cages open at the top, which can be at least partially extracted from the supporting frame in the direction of one side, either the back side or one lateral side, of the transporting unit other than the front side at which the poultry are introduced into the drawer-type cages.
