Abstract: The present invention relates to a laying machine for laying at least one flexible casing or tube, cable or wire including: a blade arrangement for making a trench in the ground, a consolidation and laying means being arranged behind the blade arrangement, for clearing and safe-guarding the trench from collapsing while laying at least one flexible casing or tube, cable or wire into the trench. A blade assembly comprising compartments for cooling fluid and air.

Abstract: The present disclosure relates to a radio system comprising an antenna device, an antenna connector arrangement and a radio transceiver with a transmitter branch and a receiver branch. The antenna connector arrangement connects the antenna device to the transmitter branch and to the receiver branch, and comprises a first tuneable band-stop filter, a second tuneable band-stop filter and a three-way-junction. The first tuneable band-stop filter is connected to the transmitter branch and a transmitter input port of the three-way-junction to filter radio signals, and the second tuneable band-stop filter is connected to the receiver branch and a receiver output port of the three-way-junction to filter radio signals. The three-way-junction comprises a first antenna port that is connected to the antenna device. The present disclosure also relates to an antenna connector arrangement, an antenna arrangement, and an electrically tuneable waveguide band-stop filter arrangement.

Abstract: A foldable seat for a rollator or a wheelchair includes a first plate and a second plate. The plates are rotatably moveable between an unfolded position and a folded position. A hinge pivotally connects said first plate to said second plate. An exemplary hinge includes at least a first cylinder integral with said first plate and at least a second cylinder integral with said second plate. The seat further includes a locking/unlocking system configured to be actuated by the user so as to lock, respectively unlock, said first and second plates into, respectively from, said unfolded position and/or said folded position. The locking/unlocking system being at least partially lodged inside said first and/or said second cylinder.
