Apparatus and method of manufacturing rope or cord wherein a double-twisting device is used in conjunction with an equalizer in a single apparatus to provide rope or steel cord of the equiverse type.

Cable and drag rope jackets are constructed from snapped together strips having streamline profile, and joints only at the leading and trailing edges of the profile. Each strip has recesses which mutually cover each other upon assembly to receive one or more cables or a rope.

In marine operations with underwater lines, such as fishing lines, a method is provided of hauling a length of such line by means of two separate and mutually spaced hauling means. A first hauling means includes a submersible hauling means adapted to be suspendedly supported in submerged position approximately at the level of said the underwater line and is able to haul the line in frictional engagement therewith. There is provided a means to maintain an oppositely directed counter balancing for...

For measuring and/or monitoring properties of yarns or ropes with the aid of an image sensor a two-dimensional image of a portion of the yarn or rope is acquired and converted to electrical image signals. The image signals are digitized in image point manner and stored in an image signal memory at memory locations assigned to the image points. By a calculating unit the values of the properties to be detected are determined from the stored digital image signals. The properties which can be measur...

A tangle composed of the end of a guiding rope and of a wire is formed and driven into the soil by a device which forms this tangle by subsequent operations and drives it into the soil.

A portable practice runway is provided with an improvement comprising cross members made of flat spring steel with the central section of the cross member thereby lying flat on the surface allowing the runner's foot to substantially fully engage the ground when the cross member is inadvertently stepped on. The cross member is preferably of one piece with the upstanding side members being formed by bends in the cross member. The upstanding legs have sufficient resiliency to flex when the cross li...

A container is suspended from four hoist ropes. One end of each rope is wound on a drum to be driven in either direction to hoist or lower the container. The second end of each rope is connected to a double acting hydraulic cylinder. The cylinders are controlled by a valve system to dampen swaying of the load to reset the ropes and for skewing, trimming and listing the load.

Tension of compensating ropes in an elevator system is electively changed to minimize horizontal vibration of the compensating ropes in tall buildings. The tension of compensating ropes is changed by a tensioning mechanism either when the horizontal movement of the compensating ropes exceeds a preset limit or when the building sway exceeds a predetermined amount. Additionally, the tension of compensating ropes can be changed when the elevator car is parked within certain predetermined top floors...

A method of and an apparatus for the combining of strands comprises swinging a hollow shaft about an axis without rotating this shaft while guiding the strands to an assembly point substantially at the pivot of the shaft. The strands are then spread to pass through a cluster of holes on a distributor plate carried by the shaft before being collected again at a closing point, the points lying substantially along a straight line including an acute angle with the axis about which the cycloidal path...

A stretcher for stretching wires and similar elements for use in fences and the like which comprises a yoke to be attached to a post or similar element, the outer portions of the yoke being provided with two opposite apertures, and a rotatable stretching element disposed between the outerportions of the yoke and provided with a through cross-aperture in which a wire to be stretched can be received. The rotatable stretching element is provided with a threaded outer end having a cross-section smal...
