Granted: 2005-08-30
Abstract: The air/fuel mixture ratio supplied to an internal combustion engine of a vehicle is modified to achieve a constant mass flow ratio in spite of changes in atmospheric temperature and pressure conditions by employing an electronic compensation system. The system has sensors which detect air temperature and barometric pressure, from which signals are developed controlling the float bowl pressure in the engine carburettors, thus modifying the air/fuel mixture ratio as desired. The system also includes provision for enriching the fuel content of the mixture supplied to the engine to provide an oversupply of fuel in cold start situations.

Abstract: L'invention concerne une lance améliorée pour injecter de l'oxygène et brûler du combustible, destinée à introduire, à des moments sélectionnés, un flux d'oxygène et/ou de combustible carboné dans l'enceinte d'un four électrique. La lance (10) comprend une partie à carter (14), un cylindre droit (24) ayant une première extrémité reliée à la partie carter (14) et une seconde extrémité reliée à l'embout (12) de la lance. L'embout (12) de la lance comprend une structure (16) à buses, ayant au moins une buse (60) pour l'injection de l'oxygène et au moins une buse (64) pour l'injection du matériau carboné, ces buses constituant ensemble un brûleur projetant un jet combiné de combustible carboné et d'oxygène provenant de la lance (10), qui peut être allumé pour produire une flamme permettant de réchauffer une charge de ferrailles dans l'enceinte d'un four électrique. Quand les ferrailles sont suffisamment fondues par l'effet conjugué des électrodes du four électrique et du brûleur, l'alimentation en oxygène et en combustible carboné peut être arrêtée et la flamme éteinte. L'alimentation en oxygène peut ensuite reprendre, à un débit réduit, pour achever le réchauffage/la coupe si nécessaire, ou à un débit supersonique pour le raffinage/décarburation du bain d'acier en fusion.

Title: Retrofit measuring device for a hay baler
Inventor: MCPHERSON BOBBY ROY
IPC: A01F15/14
Filed: 1998-01-27
Granted: 2002-07-30
Abstract: Retrofittable hay bale measuring apparatus measures the size of the hay bale being formed, and indicates the size of the bale being formed to a control and display unit. The baler operator sets the desired hay bale size and monitors the baler operation on the display. A contact wheel, which contacts the hay bale and rotates as the bale is being formed, is rotationally attached to a measuring wheel. Alternatively, the contact wheel may itself comprise the measuring wheel. The rotation of the measuring wheel is monitored by a rotation detector which generates a hay bale measuring signal, and sends it to the control and display unit. The control and display unit generates a signal which indicates to the baler when it is time to tie off a bale of hay, based upon the measuring signal.

Abstract: The present invention provides for a method and apparatus for automatically lining a container having at least one open end. A bag-type liner having a leading sealed, and a trailing unsealed, end is fed along a predetermined liner path, with the trailing unsealed end suspended above the container. A plurality of clamps grab the sides of the bag at the unsealed end and separate the unsealed end by pulling the sides apart. A vacuum is then activated to draw air out of the container through the bottom of the container, drawing the wall of the liner material against the interior surface of the container, thereby fully opening the liner in the container. If the container has two oppositely facing open ends, a vent can be positioned under one of the open ends for drawing air out from the container. If the container has only one open end, a plurality of vacuum tubes can be inserted into the bottom of the container along the interior surface of the container for drawing air out of the bottom of the container.
