Inventor: OSSSELAERE GUY HENRI JULIEN
IPC: A01D41/14
Filed: 1987-04-16
Abstract: A harvester is provided comprising: 
    - a mobile base unit (12) adapted for movement over the ground, 
    - a transversely extending crop harvesting header (20) supported from the base unit (12) for allowing pivotal movement about a generally fore-and-aft axis of the machine; and 
    - a lateral flotation system (57) for pivoting the header (20) about the generally fore-and-aft axis . 
     The lateral flotation system (57) includes :
     a) a two way hydraulic actuator means (60) extending between the header (20) and the base unit (12) for pivoting the header (20) in the one or the other direction and positioning the header (20) in a nominal position intermediate opposed extreme positions prior to starting flotation operation,   b) a pressure source (73) coupled by a pair of pressure fluid supply lines (75) to the hydraulic actuator means (60); and   c) energy storage means (69) connected to the hydraulic actuator means (60).   
     The energy storage means (69) is in the form of a hydro-pneumatic accumulator coupled to each one of the pressure fluid supply lines (75) and pressurized at a pressure greater than the working pressure of the hydraulic actuator means (60) for pivoting the header (20) in the one or other direction. The arrangement is such that, when the header (20) is positioned at a nominal position and meets an obstruction, said header (20) is permitted to temporarily pivot in the one or other direction away from its nominal position for moving said obstruction. This pivotal movement results in the gas in one hydro-­pneumatic accumulator (69) being temporarily compressed by the flow of pressure fluid out of the actuator means (60) to store energy. This pressure fluid subsequently is released back to the actuator means (60) to restore the header (20) to its nominal position upon the header (20) clearing the obstruction. At the same time, the gas volume in the other hydro-pnuematic accumulator (69) remains unchanged during this pivotal movement of the header (20) away from, the back to the nominal position whereby said other hydro-pneumatic accumulator (69) remains inoperative under this condition.

Abstract: The invention relates to a method and a device for very accurately metering a quantity by weight of food for being supplied to small livestock, such as poultry, which small livestock is present in a number of cages (1) placed one behind the other. The outflow of food from a food hopper (6) filled with food, can be stop the moment when is determined that the receiving trough (13) contains a sufficient quantity of food. 
     This quantity of food corresponds to a certain desired quantity of food per animal multiplied by the number of animals to be fed. After the receiving trough (13) has been filled it is emptied for example into a feed trough (2). The preference the device is provided with a sensor (29) or the like which can scan an indicator (30) which can be fastened to a cage (1), which indicator (30) emits a signal indicating the number of animals present in that cage (1).

Abstract: An aircraft guidance system for optimising the flight path of an aircraft in the presence of a windshear maximises the time the aircraft remains in the air and the distance travelled regardless of the magnitude of the windshear, in the presence of horizontal or vertical windshear components, while effectively minimising excitation of the aircraft's phugoid mode. A flight path angle is commanded sufficient to clear any obstacle that may be found in the airport vicinity. For longitudinal or horizontal shears, a slightly positive constant flight path angle which is a function of the magnitude of the vertical wind is added to the slightly positive flight path angle command to produce a modified command that compensates for the decrease in flight path angle relative to the ground caused by the vertical wind. The system inhibits exceeding stick shaker angle of attack by reducing the command signal until the actual angle of attack is equal to or less than the stick shaker angle of attack.

Abstract: Means for studying interactions of a predetermined retrovirus with cell lines susceptible of being infected by said retrovirus. It implements a defective recombinant retrovirus derived from the retrovirus in question, containing the parts acting in ''cis'' of said retrovirus which normally provides for its packing, its reverse transcription into a DNA molecule and its integration into the genome of the host cell. Said recombinant retrovirus is characterized by the partial or total substitution of sequences coding for its viral proteins by a genic sequence coding itself for a protein acting as labelling agent for the infected cells. The detection of the labelling agent in the cells of which the infection sensitivity is to be studied proves their capacity to be infected by the wild retrovirus. The cells infected by the defective recombinant retrovirus may, in turn, be used as reagent for the detection in the wild retrovirus in an exterior biological sample. The presence of the wild retrovirus is evidenced by the complementation in trans of the provirus which is then produced by said cells andwhich may then be detected.

Abstract: The transponder is constituted by a waveguide (1) having a large face (2) including longitudinal slots (3) and pairs of slots distributed along the axis (WW') of the large face at one pair per n longitudinal slots. Each pair is constituted by two transverse slots (4, 4') situated facing a longitudinal slot. The presence of a pair corresponds to a one value bit and the absence of a pair corresponds to a zero value bit. The longitudinal slots receive radiation from a transmit antenna (A1) including a low frequency and a high frequency. They radiate to a first receive antenna (A2) using radiation at the high frequency. The pairs radiate to a second receive antenna (A3) using radiation at the low frequency. The antennas are fixed relative to one another and they move relative to the transponder.

Abstract: Dense metal oxide and metal sulfide particles, i.e., ceramic particles are produced from a liquid base precursor of the ceramic the precursor is selected from the group consisting of: (1) a concentrated solution of a solid active ingredient in the liquid carrier medium; and (2) an active ingredient in a solution, suspension, or dispersion capable of forming a gel phase. The active ingredient is capable of generating the ceramic in situ upon application of heat to the precursor. The process requires generating precursor droplets having a mean diameter of up to about 3 microns and then heating the droplets at a temperature of at least about 400°C for a time sufficient to remove at least a substantial portion of the carrier medium from the droplets. The process further requires converting at least a portion of the solid active ingredient to the ceramic to produce a solid, spherical particle of the ceramic. In general, the particles so produced have a mean diameter of less than about 1 micron.
