    摘要: A sidewall air cushion vehicle or side effect ship (SES) includes a pair of parallel body members which are connected to each other by a rigid structure above the water surface, a flexible bow skirt in the front of the vehicle and a flexible stern skirt in the rear of the vehicle, an air cushion space between said bow and stern skirts, partition means extending transversely to the fore-aft-direction of the vehicle and dividing said space at substantially the mid thereof so as to provide a pair of compartments which are separated from each other by said partition means in a substantially fluid tight manner, at least one fan means for generating air cushions in said compartments, and sensor means for sensing the pitch angle or the pitch angle velocity of the vehicle to be used as control parameters for control of the pressure of the air in the compartments; the partition means and/or a bypass passage bypassing said partition means includes flow control means having an adjustable flow cross section and adapted to be actuated by actuating means which is controlled by said control means so that said flow cross section is adjusted in response to the pitch angle and/or the pitch angle velocity of the vehicle and/or the pressures in said compartments.

    摘要: A method and apparatus for severing trees and other similar objects extending at least partially above and at least partially below the surface of the ground. A frame member which is mountable on a vehicle is moved in a substantially horizontal plane above the surface of the ground. A pair of circular cutting disks having sharpened peripheral edges are rotatably mounted on the frame laterally spaced from each other. The disks are arranged such that the imaginary planes formed by the sharpened edges of the disks are inclined from the surface of the ground and intersect at a point below the surface of the ground, such that the inclined planes have opposite slopes and such that the sharpened edge of one of the disks is substantially adjacent the sharpened edge of the other disk.

    摘要: A frequency converter assembly includes a frequency converter, a motor, and an intermediate component. The frequency converter includes a converter housing with an opening. The motor includes a motor having a motor housing with a terminal block. The intermediate component is attached to the motor housing around the terminal block and is attached to the converter housing such that the intermediate component is between the housings with the terminal block being accessible through the opening of the converter housing.

    摘要: A coarse grained cemented carbide is produced by sintering a mixture of coarse grain carbide particles having an average particle size of at least 10 microns and a nickel binder in particulate form. The cemented carbide has particular use in the manufacture of a cutting element for a soft rock mining tool or road planing tool.
