摘要:
A method for detecting the angular position of a gas knob of a motorcycle; the method presents the steps of: detecting simultaneously four mutually redundant measurements of the angular position of the gas knob by means of two mutually independent angular-position sensors forming part of an acquisition system; making a cross comparison two by two between the four measurements for diagnosing any possible malfunctioning of the angular-position sensors; and determining the angular position of the gas knob, using at least one measurement supplied by an angular-position sensor operating properly.

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.

A transporting unit for live poultry on board a truck includes a supporting frame and a plurality of drawer-type cages having a lateral wall without aeration openings and intended to be selectively positioned at one side or the opposite side of the supporting frame, depending on the climatic and environmental transport conditions. The drawer-type cages are arranged in a single pile or in two adjacent piles, and in both cases the arrangement is such to be able to occupy the entire width of the loading deck of a truck.
摘要:
A method and apparatus for stunning animals intended to be slaughtered wherein the animals are introduced into and displaced from above downwardly in a closed environment (1) containing a stunning gas mixed with air at an increasing concentration with a top to bottom vertical gradient from a preset initial value to a final higher value. The stunning gas concentration is detected in the upper area (2) of the environment (1) and in case the detected concentration is higher than the preset initial value, the external air is automatically supplied to the upper area at a pressure slightly higher than the atmospheric pressure until the preset initial value is restored.

A method of determining opening of an intake valve of an internal combustion engine, the method including the steps of: determining the time pattern of an intake pressure in an intake manifold of the internal combustion engine, the time pattern of the rotation speed of a drive shaft of the internal combustion engine, or the time pattern of a voltage at the terminals of a battery of the internal combustion engine; determining an intake-frequency component of the intake pressure, the rotation speed, or the voltage; and determining opening of the intake valve as a function of the intake-frequency component of the intake pressure, and also as a function of the intake-frequency component of the rotation speed or voltage.
摘要:
A transporting unit for live poultry including a quadrangular supporting frame and a plurality of drawer-type cages open at the top, arranged in a superimposed condition in the frame and slidably displaceable outwards through a first side of the supporting frame, in a partially extracted condition to enable loading of the poultry from a site located at a second side of the frame from the lowermost drawer kept inserted within the frame. The frame is configured to enable simultaneous loading of the poultry into each drawer-type cage from an additional site located at a third side of the supporting frame which is opposite to the second side.

摘要:
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.
摘要:
An acquisition system for detecting the angular position of a gas knob of a motorcycle; the acquisition system is provided with: a fixed supporting body; a mobile element, which is mounted mobile in the supporting body; a transmission device, mechanically connected to the gas knob and to the mobile element for transmitting the motion from the gas knob to the mobile element itself; and a main position sensor, which is carried by the supporting body, is coupled to the mobile element for determining the angular position of the mobile element, and is designed to provide two mutually redundant measurements of the angular position of the mobile element.
