The present invention is directed to a composition of polystyrene or polypropylene with at least 0.5% (w/w)of an additive or wetting agent, the article of manufacture comprised thereof, such as a mold for making contact lenses and the mold assembly containing said mold, and the use of such mold so to minimize defects, such as holes, puddles, chips and tears in the lens.

Mold material made with additives

A method and apparatus for the manufacture of lens molds used in the formation of optical contact lenses, the apparatus including a center gate aligned on the central axis of the lens mold cavity for delivery of the melt polymer in an axisymmetrical manner. The methodology produces lens molds of extremely precise dimensions as measured against lens molds produced with side gated technology.

Apparatus and method for producing center gated lens molds for contact

The present invention is directed to a composition comprising polystyrene with at least 0.1% (w/w) of an additive, the article of manufacture thereof, such as a mold for making contact lenses and the mold assembly containing said mold, and the use of such mold so to facilitate demolding from a two mold assembly in the process of making contact lenses.

A sealing device automatically seals a gap between a door bottom and a floor in response to closing movement of the door. The sealing device includes a support element attachable to the door bottom, a seal actuating element movably supported from the support element by spring elements, and a sealing element carried by the seal actuating element. The sealing device may be mounted to the inside or outside of a door, or mortise-mounted in the door, and may be mounted to left- or right-opening hinged doors, or to sliding or articulated closures, and may be provided as an after market or OEM device. The spring elements in the preferred embodiment are one-piece and are integrally connected to both the support element and the seal actuating element, thereby forming a one-piece sealing device preferably made of plastic. In embodiments where lateral movement of the seal actuating element is required to seal the gap, a projection on the seal actuating element is engaged by a door jamb surface or an element attached thereto during door opening and closing. A cover for the device is attached without fasteners e.g., by snap-fitting or slide fitting, and may act as a kick plate, and may be decorative. The length of the sealing device may be easily reduced or expanded to fit various size doors. The invention also provides a device which holds the seal actuating element a predetermined distance from the support element during installation of the device on the door to facilitate installation.
