  • Patent number: 10480001
    Abstract: The invention provides a method for the generation of a monoclonal plant cell line from a heterologous population of plant cells, comprising the following steps: (a) provision of a heterologous population of plant cells; (b) preparation of protoplasts from said heterologous population of plant cells; (c) separation of single protoplasts by subjecting the preparation of protoplasts to flow cytometric sorting; (d) regeneration of a separated single transformed protoplast until the formation of a microcolony by co-cultivation in the presence of feeder cell material; (e) removal of the microcolony from the feeder cell material and cultivation of the microcolony until the formation of a monoclonal plant cell line.

  • Patent number: 6802462
    Abstract: A hand shower has a handle having an outer part extending along a handle axis and having an outer face and a shower head forming at least one spray opening directed along a spray axis extending nonparallel to the handle axis. A pivot between the handle and shower head allows pivoting of the head on the handle about a pivot axis inclined at 30° to 90° to the handle axis, normally 45°. The pivot axis extends at an angle between 35° and 50° to the spray axis.

  • Publication number: 20040006818
    Abstract: A shower head has a body having an inlet adapted to be connected to a source of pressurized water and an opposite end face formed with a plurality of arrays of spray openings. Respective sprayers in the body at the spray-opening arrays periodically block and unblock same and thereby cause pulsating streams of the water to issue therefrom.

  • Patent number: 6550079
    Abstract: A shower has an elongated C-section holder tube having a laterally open full-length slot open at both ends, a bracket securing the holder tube to the wall, and a shower head. The head has a guide part snugly engageable in and slidable along the holder tube, a narrow neck projecting laterally from the guide part out of the tube through the slot thereof, and a spray part provided with spray holes and mounted on the neck outside the tube. A hose has an inner end connected to the guide part and communicating therethrough with the spray part and an outer end connectable to a source of water under pressure for spraying water from the holes of the spray part. The head is slidable along the holder tube with the hose extending from the guide part inside the holder tube and out of the open end of the holder tube.

  • Patent number: 6442775
    Abstract: A shower fixture has a base adapted to be fixed to a wall, connected to a pressurized-water supply, and having a pressurized water outlet. A pair of generally parallel and spaced tubes have inner ends pivotal about an inner horizontal axis on the base and outer ends. At least one of the tubes is internally connected at the base to the outlet so that pressurized water can flow from the supply through the base to the tube. An element joins together the two tubes for joint pivoting. A shower head mounted between the outer ends is pivotal on the tube about an outer horizontal axis and is connected internally at the outer axis to the one tube so that water from the one tube can flow into the head.
