20090308712 | ESCALATOR - An escalator includes a plurality of steps or panels, a chain for driving the steps or panels, at least one chain wheel around which the chain is deflected and wherein the chain, starting from the chain wheel, forms an upper strand and a lower strand. There is also provided a device for the polygonal compensation of the movement of the at least one chain wheel. The effective lever arm of the chain on the at least one chain wheel in the upper strand is substantially equal to the effective lever arm of the chain on the at least one chain wheel in the lower strand. | 12-17-2009 |
20100273589 | SOUND-DAMPING UNIT FOR A SPROCKET, AND SPROCKET - A sound-damping unit for a sprocket has a mounting foot for connection to a sprocket and an elastic body placed on the mounting foot that is suitable for cushioning a chain running onto the sprocket. The elastic body is provided with a protective cap or protective layer. A sprocket according to the invention includes a circular sprocket disc having a number of teeth and tooth gaps in the circumferential direction. The sprocket is equipped with at least one sound-damping unit that is configured to reduce the noise upon a chain running onto said sprocket. The sound-damping unit is at least one sound damping unit as above. | 10-28-2010 |

20080203681 | Quick-release jaws with single-piece bearing chuck - A workholding chuck can use actuating members that pivot within a non-split unitary front bearing. The non-split unitary front bearing can include pockets in its central bore that can allow a spherical section of an actuator arm to be inserted into the bearing. The spherical section can include radially recessed areas to facilitate the insertion into the bearing. The jaws can be retained to the actuator arms through the use of a quick-release assembly. The quick-release assembly allows the jaws to easily and quickly be changed to allow the chuck to grasp different workpieces. | 08-28-2008 |
20090160140 | HYBRID LATHE CHUCK - A system, in certain embodiments, includes a cutting tool, a drive, and a chuck rotatable by the drive. The chuck includes a body having a core disposed in a shell, wherein the shell is made of a metal and the core is made of a composite material. The chuck also includes a set of jaws coupled to the body, wherein the jaws are configured to hold a work piece adjacent the cutting tool. | 06-25-2009 |
