The contact lens has a very high oxygen permeability comparable to conventional transparent silicone rubbers so as to ensure a long time of continued wearing of the lens on the cornea with no adverse physiological influences and the material still has much better mechanical workability for precision shaping into a lens form than the transparent silicone rubbers.

Abstract: A tension tie member is anchored between two spaced locations on a structure, such as a diagonal cable in a stayed girder bridge. The tie member is supported on the structure adjacent at least one anchor location by an annular bearing member encircling an outer protective casing of the tie member. The bearing member is positioned within an annular chamber in the structure at the point where the tie member extends through the structure toward the anchor location. The diameter of the annular chamber is larger than the diameter of the tie member so that there is a certain amount of play between the bearing member encircling the tie member and the surface of the annular chamber whereby lateral movement of the tie member can occur. With the tie member anchored in place the space between the outside of the bearing member and the inside surface of the annular chamber can be filled with grout to support the tie member.

The device can grip the member and place it carefully on a surface where it is surrounded laterally by similar members. In the placing operation the member gripped and the laterally surrounding members are not deformed. The gripping arms are pivoted at one end and grip the member at the other. The pivoted ends of the gripping arms can be moved away from or toward one another while being pivoted for effecting gripping or releasing of the member.

Abstract: A walking beam furnace comprises a hearth formed by fixed and walking beams disposed with their axes in the feed direction. Both the walking beams and the fixed beams are divided at positions spaced apart in the feed direction into sections, and each section of each beam is staggered relative to the adjacent section. As a result, the material to be annealed comes into contact with the cooled fixed beams at different positions at each of the conveying pauses and temperature balancing takes place at the points of contact.

Abstract: In the assembly of a tension tie member between spaced anchors when the tie member is made up of a number of individual tension elements, such as steel wires, steel strands or the like, enclosed within a tubular sheathing, the tension elements are inserted individually and successively between the anchors and it is necessary to insert the annular wedges which anchor each element before the tension elements are released from a threading device. To prevent the annular wedges from prematurely entering into the boreholes in the anchor plate, an auxiliary plate is positioned spaced from the anchor plate. The auxiliary plate has at least one through borehole axially alignable with the boreholes in the anchor plate. A tubular section is secured to the auxiliary plate and forms an extension of the borehole therein. An annular wedge to be inserted into one of the boreholes and the anchor plate can be held on the tubular section by resiliently expanding the wedge about the outer surface of the tubular section.
