Abstract: In a separating device, the heart, lungs and liver are separated from the viscera of a slaughtered bird by conveying these organs, including the gall-bladder, connected to the bird, essentially parallel to the path of the bird with a helical roller. First the heart and lungs are separated from the liver by cutting through the tissue connecting the heart and lungs, and the liver. Next, the liver is separated from the remainder of the viscera by increasing the distance between the liver and the gall-bladder, and cutting through the tissue connecting the liver and the gall-bladder.

Abstract: A device for removing abdominal fat from a slaughtered bird, comprising a scraper element which is movable through an abdominal opening between the legs, and a device for discharging the fat scraped off by the scraper element, further comprising an elongated hollow mandrel, which can be connected to a vacuum source. The mandrel at the end facing the bird is provided with a suction aperture, at a distance from which the scraper element is fitted, said scraper element being provided with a scraping edge for interacting with the complementary-shaped edge of a supporting element, for scraping the abdominal fat along the scraping edge during a movement of the scraper element interacting with the supporting element away from the bird. An installation may comprise a number of such devices.

Abstract: An even-bounce reflector for calibrating the orthogonal polarizations of a radar system. A segment of a cylindrical reflector is fixed to a flat plate reflector with the angle between the segment of a cylinder and a flat plate being substantially 90 degrees.

Abstract: Device for cutting out the vent of a slaughtered bird, including an elongated centring pin, a rotatable cutting element with an axially directed cutting edge, and an axially movable positioning element. In an end position of the positioning element relative to a thickened end portion of the centring pin between these two elements an annular space is formed for the accommodation of the orbicular muscle of the vent, while in this end position between the positioning element and the thickened end portion of the centring pin an annular gap remains open with a width which is smaller than the thickness of the orbicular muscle.

Abstract: A refractive velocimeter apparatus for measuring fluid velocity in a stack includes an optical instrument positioned on the stack for generating an optical signal, which instrument includes a lens for collimating light and positioned for detecting the collimated light along a first direction through the stack and through the fluid flowing within the stack, and a first reflector positioned for reflecting at least some of the collimated light along a second direction, parallel and opposite to the first direction, through the stack and through the fluid flowing through the stack. A second reflector is positioned for reflecting collimated light away from the second path and out of the instrument as the optical signal. A laser is positioned remotely of the stack and light from the laser is provided to the optical instrument through a fiber optic cable.

Abstract: A device for making an incision around the vent of a slaughtered bird and pulling the end of the rectum out of the opening thus made, including: a centering pin which is movable relative to the bird, and is provided with a thickened end portion; and a cylindrical rotary cutter with an annular cutting edge, which cutter is movable relative to the bird and is movable coaxially relative to the centering pin. The device further comprises one or more holding elements which are recessed relative to the cutting edge and which can interact with a contacting surface of the thickened centering pin end portion situated opposite them for holding the vent between these elements and the contacting surface near or at the orbicular muscle. The drive of the cutter is designed in such a way that the cutter carries out a small number of turns during the cutting operation.

Abstract: A method for producing a hydraulic binder using partially calcined raw meal entrained in the kiln off gases. The raw meal flow form the lowermost cyclone is interrupted at or near the junction of the meal chute, kiln inlet and riser duct. This flow interruption causes turbulence in the partially calcined meal facilitating dust entrainment in the gas. The splash plate can be selectively adjusted to entrain more or less raw meal. The entrained meal is drawn off from the riser duct through a kiln bypass duct, processed and hydrated to convert the calcium oxide in the meal to calcium hydroxide.

Abstract: A poultry feeding device comprises an essentially dish-shaped pan, the bottom of which is provided with an upright part. A drop tube for the supply of feed can be moved over a limited, variable distance relative to the bottom of the pan to form a first feed supply opening of variable size. The drop tube has one or more second feed supply openings. In the bottom position of the drop tube the first feed supply opening is closed and the second feed supply opening(s) are opened, and in the top position of the drop tube this is reversed. The upright part of the bottom of the pan extends in the drop tube, and in the bottom position of the drop tube the top side of the upright part reaches to the second feed supply opening(s) and at that point shuts off the drop tube.
