Abstract: Athletic socks and associated methods of manufacturing are disclosed. An example athletic sock includes a body defining a closed end proximate a user's toes and an open end that at least partially encircle the user's leg. The sock includes an ankle portion formed of a cut-resistant material that at least partially surrounds the ankle of the user. The sock includes a leg portion extending between the ankle portion and the open end. The leg portion defines a calf section that surrounds at least a portion of the user's leg and a shin section that accommodates a shin guard received by the athletic sock. The sock includes a foot portion extending between the closed end and the ankle portion. The foot portion defines a heel section and toe sections that include tacky yarn knitted such that the same yarn is disposed on both an exterior and interior surface of the sock.

Abstract: An overhung steam turbine is described which features a seal assembly and a bearing assembly to minimize axial shaft movement. The seal assembly forms a pressure barrier between a relatively low vacuum exhaust region and an exhaust cavity disposed at one end of the rotor shaft to minimize the pressure differential across the ends of the shaft and the resultant thrust force of the rotor shaft against the turbine casing. A bearing assembly is provided which includes a pair of journal bearings and a pair of oppositely disposed thrust bearings. In one embodiment one thrust bearing is connected by an adapter ring which is mounted to a horizontally split bearing casing. In another embodiment, the thrust bearing is carried by one of the journal bearings. The journal bearings are preferrably connected by horizontally split ring bearings to facilitate insertion and removal of the bearings without removing the overhung shaft.

Abstract: A three part split shaft seal assembly is disclosed which is particularly adapted for use in an overhung steam turbine. In one embodiment the assembly is located between the shaft opening of the turbine case and a horizontally split shaft bearing case. To facilitate axial insertion and removal of the assembly, the seal assembly is formed from three pairs of split ring seals. Proper axial alignment is maintained by stand-offs or dowel pins located between two of the split ring seals. In one embodiment a snap ring received within an annular groove in the turbine housing holds two of the seal rings against axial movement. In that embodiment set screws carried in one ring seal are used to seat and align two ring seals of the assembly relative to the turbine casing. A pin holds two of the ring seals against relative rotational movement. In another embodiment, a split spacer ring is used to maintain correct spacing and the third seal is used to position and hold the other two seals axially aligned to each other.
