Abstract: A system for controlling the flow of turbined water from a plurality of hydroelectric plants arranged in series along a watercourse with an open channel flow, defining upstream of each plant, a plurality of head races subject respectively to hydraulic flow and level constraints. The flow of water turbined by each of the plants is controlled by a flow setpoint. The system includes regulation of a global electrical production power set-point for the plurality of hydroelectric plants by a flow regulation setpoint taking into account the flow setpoint of each of the plants. The flow regulation setpoint determined by the regulation is weighted for each of the plants by weighting coefficients as a function of the respective hydraulic characteristics of the head plurality of races.

Abstract: An upper guide track assembly for a retractable screen is described. The assembly comprises a U shaped guide channel, a track attachment member for attaching the assembly to a support, a track outer member connectable to the attachment member and a screen retaining member within the guide channel. The retaining member receives and retains an upper edge of a screen. The retaining member has two resilient wings extending from either side of the body. Each wing is biased towards a position in which the distal end of each wing is away from the body. The wings are moveable against the bias to a retracted position. When the retaining member is retained in the guide channel, each wing is held in the retracted position against the bias. This allows an upper edge of a screen retained by the screen retaining member to be biased in the vertical direction.

Abstract: The disclosure relates to the field of providing a flexible screen which is extensible and retractable across an opening. It is desirable to provide a bottom guide track which is convenient to fit and with a low profile. The disclosed guide track arrangement provides an elongate mounting member for securing to a support that forms part of the opening, and which provides at least one elongate connection recess; and an elongate track member, formed separately from and attachable to the mounting member, and having a track region with an elongate guide recess for slidingly retaining an edge of a flexible screen. The track member has at least one engagement part engageable into the complementary connection recess by lateral movement of the track member to connect the track member to the mounting member.

Abstract: The invention concerns a system for controlling the flow of turbined water from a plurality of hydroelectric plants (1, 2, 3, 4, 5) arranged in series along a watercourse with open channel flow, defining upstream of each plant a plurality of head races subject respectively to hydraulic flow and level constraints, said plurality of hydroelectric plants, in which the flow of water turbined by each of said plants is controlled by means of a flow setpoint (QCui), said system comprising regulation of a global electrical production power setpoint (Pc) for said plurality of hydroelectric plants by means of a flow regulation setpoint (QRGP) taken into account by the flow setpoint (QCi) of each of said plants, and in that said flow regulation setpoint (QRGP) determined by said regulation is weighted for each of said plants by means of weighting coefficients (?i) as a function of the respective hydraulic characteristics of the head races defined upstream of said plants.

Abstract: A mounting arrangement comprised of a first component for attachment to a support, and a second component supportable by the first component. The first component has a first side which is in use distal from the second component and provides a supporting portion spaced from the first side. The second component provides an engagement portion for engagement with the supporting portion. The mounting arrangement provides a restraining part moveable between a restraining configuration for restraining disengagement of the engagement portion from the supporting portion, and a release configuration for allowing disengagement of the engagement portion from the supporting portion. The mounting arrangement further provides a securing component which is insertable between the second component and the first side of the first component to restrict disengagement of the engagement portion from the supporting portion.

Abstract: An apparatus for retaining a blind comprises: a first elongate element for attachment to a supporting structure; a second elongate element attachable to the first elongate element, in order to at least partially form a guide track providing a guide channel in which a part to be guided may be constrained, the first and second elements together at least partially defining the external surfaces of the guide track. The second elongate element is attachable to the first elongate element by displacement of the second element relative to the first element. The direction of displacement may be a direction substantially transverse to the direction of elongation of the first element.
