Abstract: A boom includes a plurality of boom sections joined end to end. Each boom section includes two or more parallel inflatable chambers which are joined with a weighted curtain which is reinforced for strength. Boom sections are stored compactly on respective reels. A substantial number of reels are arranged compactly in the hold of a carrier vessel which is smaller in size and has greater speed and maneuverability than vessels carrying known oil spill containment systems. Boom sections are consecutively unwound from their respective reels and connected end-to-end as they are deployed to form a continuous boom. The boom sections unwind naturally from the reels as the carrier vessel moves through the water away from a tender vessel holding the first end of the boom. The boom's deployment is controlled by a brake on an idler roller and a hydraulic crane's drive wheel on the reel, thus limiting manual handling to lighter-weight tasks.

The secondary structure includes a plurality of individual fingers positioned and arranged to extend below the level of the lower edge of the primary snow removal device for engagement with the surface being cleaned. A separate spring biasing means is provided for each finger for independently extending each finger to follow uneven portions of the surface being cleaned and thereby loosen and remove residual snow and ice compacted and left by the primary device.

Abstract: Method for producing a narrow or slit wall (42) in soil (22) by means of a driver (10) with at least two and preferably three vibrating tubes (I, II, III) and guide blades (28, 30, 32) between the vibrating tubes. Following penetration of the driver into the soil, during the withdrawal process of the latter, injection material (40, 44) is loaded into the drilled cavities. During the next work step, the driver is lowered into the soil so that the rearmost vibrating tube (I) is lowered into the still-soft injection material (40) which was added during the previous withdrawal of the foremost vibrating tube (III). By monitoring the power draw of the vibrating motor on the rearmost vibrating tube (I) and regulating this power draw to keep it to a minimum value, removal of the rearmost vibrating tube from the still-soft injection material (40) is prevented. As a result the seal between the successive sections of narrow wall (42) is ensured.

Abstract: A C-clamp and a wedge of an adapter for an excavating bucket have locking parts which substantially eliminate any tendency for the wedge to become loosened from a space between the C-clamp and a wedge block. Spring loaded teeth in the front surface of the C-clamp are received in corresponding notches in the juxtaposed rear surface of the wedge. As the wedge is driven into its operating position, the spring loaded teeth in the front of the C-clamp alternately move into and out of the adjacent notches until the wedge is tight and as the teeth are received in the notches, thus locking the wedge in place. The wedge is removed by driving the wedge block downwardly, shearing a shear pin, thereby allowing the wedge block, the wedge and the C-clamp to be separated from the adapter and fall to the ground.

Abstract: The invention concerns a weir with an on a horizontal axis tilting gate (1). The control is automatic and completely mechanical and operates without an external source of energy. The control uses a float/counterweight (4) placed in an enclosure (5) which is in connection with the upstream level. The float/counterweight (4) is connected to the equator (13) on the gate (1) by a transmission mechanism consisting of (7), (10) and (11). The float/counterweight (4) is in balance with the hydraulic forces on the gate (1). The tilting axis is placed about 0.4 of the height of the gate (1) from the underside.During large discharges the gate (1) tilts further to increase the flow. This enables the weir to establish within shorter time the desired level. A horizontal submerged grate (15) prevents choking of the weir.The gate (1) can adjusted vertically by a leadscrew (16) to set the weirlevel. A threshold-beam (20) is connected to guidings (17) to the gate-equilibrium by every adjusted height.
