  • Patent number: 9352935
    Abstract: A tension member for an elevator system has an aspect ratio of greater than one, where aspect ratio is defined as the ratio of tension member width w to thickness t (w/t). The increase in aspect ratio results in a reduction in the maximum rope pressure and an increased flexibility as compared to conventional elevator ropes. As a result, smaller sheaves may be used with this type of tension member. In a particular embodiment, the tension member includes a plurality of individual load carrying cords encased within a common layer of coating. The coating layer separates the individual cords and defines an engagement surface for engaging a traction sheave.

  • Publication number: 20080261739
    Abstract: The invention relates to V-ribbed belts (1) which have ribs (5) which run at least on a first side in the longitudinal direction of the V-ribbed belt and which are formed by thermoplastic shaping, and the first side has a layer composed of a textile warp-knit fabric (7) composed of two different yarns. In order to provide better noise reduction, the warp-knit fabric is constructed from a first yarn composed of filaments with a module of more than 5 N/1000 dtex, based on 5% extension, and a second yarn composed of filaments with a module of less than 2 cN/1000 dtex, based on 5% extension, wherein the first and the second yarn in each case form a coherent network, and the yarns are not twined around one another. V-ribbed belts can be formed effectively with an elastic warp-knit fabric of said type, whose extension is based not only on the construction of the knitted fabrics. It is surprising that the belts maintain the good noise properties both in the new state and also after a relatively long service life.

  • Patent number: 5961412
    Abstract: A fabric 3 for power transmission belt to be adhered to a belt body 2 of a V-ribbed belt 1 is formed such that carbon fibers with electric conductivity are mixed through spinning into a fabric material such as cotton, nylon and polyester. This prevents the belt from producing a beating sound and producing worn-out dusts in the use as a power transmission belt and enhances the electric conductivity of the power transmission belt to successfully prevent electrostatic charge of the belt.

    Abstract: A robot with a base, a first link connected to the base by a shoulder joint, and a second link connected to the first link by an elbow joint. A shoulder motor drives the shoulder joint, and an elbow motor drives the elbow joint. An upper elbow pulley is coupled to the first link. An end effector pulley coupled to the upper elbow pulley, and a dual-bladed end effector driven by the end effector pulley. The diameter of the upper elbow pulley and the diameter of the end effector pulley are related by a 1:2 ratio. Ferro-fluid seals are used to seal each joint. A static seal joins the seams of the links. Each arm link has a particle filter. The robot can communicate electrical signals through the revolute joints with a conductive slip-ring assembly. Alternately, the joint may have an inner cylinder and an outer cylinder, and a cable may be coiled between the cylinders.
