摘要： A watertight seal (1) between two adjoining channel-shaped concrete elements (2) has an elastic sealing strip (3) sandwiched between a socket (5) of one concrete element (2) enveloped by the socket (5). The sealing strip (3) is recessed and has a transverse profile such, that when the socket is slid over the wedge (7), material (12) of the sealing strip (3) shifts in a direction contrary to movement of the socket in order to prevent damage of the sealing strip.

摘要： Method of separating a mixture of a carrier medium and at least one substance insoluble therein, for example, water and oil or gas and soot, in which the mixture is separated in three steps, i.e. a first step in which the mixture is passed for coalescence of the substance through a first packet of moving filter material, a second step in which the substance coalesced segregates from the mixture by gravity and a third step in which the remainder of the substance and the other packet of filter material is filtered out.

摘要： The method of dredging accurately to a desired profile contour with a cutting dredger involves the operation of a cutting assembly, the cutting tools of which describe a predetermined cutting envelope, and swinging the cutting assembly while the dredger is anchored at a known point. The known point is established by means of land-based radio beacons and an aerial aboard the dredger, the dredger being anchored at the known point while the longitudinal axis of the dredger is aligned or substantially aligned with the longitudinal axis of the desired profile contour. As the dredger is swung with the cutting tools engaging the material to be dredged, the location of geometric points of the dredger assembly are repetitively calculated with respect to the coordinate system of the desired profile contour, taking into account various angular relationships between and among such points and by also taking into account motions of the dredger as affected by wave and/or tide actions. The swinging is terminated when the cutting point on the predetermined cutting envelope closely approaches the desired profile contour.

摘要： Hard ground beneath a water surface is controllably cut away by a device ch includes a buoyant body having a work support depending therefrom and forced against the hard ground so as partially to support the weight of the body. A cutter assembly is releasably clamped to the work support and the clamp has arms connecting it to a short, rigid carrier which mounts a rotatable cutter head at one end. The arms allow the carrier to swing about a horizontal axis and a vertical axis and hydraulic motors are provided to sweep the carrier about such axes in controlled fashion. A winch on the body allows the carrier to be clamped at desired vertical positions on the work support.

摘要： A device for separating water from light-weight and/or heavy substances contained therein. The separation takes place in a packet of parallel separation channels.In order to prevent that too many light-weight substances enter the upper separation channels, the flow into the upper separation channels is throttled.Also the lower separation channels may be throttled for restricting the heavy substances entering therein.

摘要： Rigid pipe sections of a dredger are pivotally connected to allow universal movement therebetween and a flexible, elastic bellows communicates the adjacent ends of the pipe sections. The bellows in its free state is prestressed so as to be under compression and is further compressed when in place between the ends of the pipe sections.
