  • Publication number: 20230399122
    Abstract: A method for determining at least one minimum power margin of a hybrid drive train for a transport vehicle, each drive element being associated with at least one power source and at least one power consumer. The method including a step of acquiring measurements of power parameters, a step of comparing each measurement with at least one limitation threshold, so as to deduce therefrom at least one gross margin, a step of converting the gross margins into refined margins expressed according to the same common magnitude, a step of transposing into standardised margins at least at one reference point, a step of determining a source power margin and a consumer power margin at said reference point and a step of determining the minimum power margin by selecting the lowest power margin.

  • Publication number: 20230138626
    Abstract: An aircraft with an electrical network including electrical subnetworks; a turbo generator including a gas turbine, an electricity generator with permanent magnets having phase groups respectively connected to the electrical subnetworks, and, for each phase group, an isolation device; and a control device designed to detect a short circuit in at least one of the phase groups, each phase group in which a short circuit is detected being described as defective and each other phase group being described as healthy and, in response to the detection of the short circuit, to disconnect this defective phase group from its associated electrical subnetwork and to command the shutdown of the gas turbine. The control device is also designed, in response to the detection of the short circuit, to keep each healthy phase group connected to its electrical subnetwork.

  • Patent number: 5429247
    Abstract: Method and apparatus for screening peat moss material. The method comprises the steps of forming an aqueous slurry of peat moss material and flowing the slurry on a screen to separate fines from coarser particles in the slurry. A spray of relatively large water drops is directed at the slurry to agitate the coarser particles blocked by the screen in order to dislodge fines adhering thereto, whereby the fines freed from the coarser particles are allowed to egress the slurry through the screen. The water spray also has the effect of clearing the screen of fines which clog the screen openings. The invention also comprehends a method and apparatus for screening peat moss material, comprising the steps of flowing an aqueous slurry of peat moss material on a sieve to extract from the slurry excessively large particles, and washing the rejects remaining on the sieve to dislodge therefrom smaller particles of acceptable size which are returned to the slurry.

  • Patent number: 4676871
    Abstract: Dry laid board comprising peat moss is provided and made by harvesting peat moss having a degree of decomposition of H-1 value as measured by the Modified Von Post Scale, individualizing the harvested peat moss, drying the individualized peat moss and entraining the peat moss in a gas stream. The entrained peat moss is then condensed to form a low density peat moss containing board which is subsequently calendered for use in such products as dressings, diapers and sanitary napkins.
