  • Patent number: 8905388
    Abstract: A block piece for holding a spectacle lens blank has a basic body with a workpiece mounting face portion against which the workpiece can be blocked with a blocking material, and a clamping portion via which the blocked workpiece can be fixed in a machine/apparatus for processing it. The basic body is made substantially of a material having a defined low water absorption and/or is sealed to at least reduce outgassing of water moisture under vacuum conditions, so that the block piece can be used also in vacuum coating processes. Alternatively or in addition, the clamping portion is constructed to be clamped by forces directed essentially perpendicular to the radial direction to cancel out each other and not deform the basic body, and/or the workpiece mounting face portion is provided with a predetermined amount of prism.

  • Patent number: 8480898
    Abstract: A membrane module for an immersed operation has a fiber bundle of hollow fiber membranes which are cast into a headpiece and in immersed operation are surrounded by a liquid to be filtered. The module has a permeate collection chamber connected to the headpiece with an outlet for permeate draining from the interior of the hollow fiber membranes, and a gas supply having a pipe guided by the headpiece. The pipe terminates in the interior of the fiber bundle and has a gas outlet for a gaseous medium, which after the transfer from the pipe to the liquid to be filtered rises as bubbles between the hollow fiber membranes. The fiber bundle is divided into sections and free spaces remain between the sections which extend from the pipe to the outer circumference of the headpiece and promote an inflow of the liquid into a foot area adjoining the headpiece.
