Title: Apparatus for demolding a lens mold assembly
Inventor: WIDMAN MICHAEL F
IPC: B29L11/00
Filed: 1997-07-01
Granted: 2001-12-11
Abstract: Demolding apparatus for reliably and repeatedly mechanically separating contact lens mold assemblies without damaging the contact lens formed therebetween. The mold assembly includes a frontcurve mold having a central mold section with a surrounding flange, and a corresponding backcurve mold also having a central mold section with a surrounding flange, with a contact lens being molded therebetween. The demolding apparatus includes a conductive heating probe which contacts the backcurve mold of the lens mold assembly to conductively heat the backcurve mold. Heat is conducted by the backcurve mold to cause a temperature gradient between the backcurve mold and the lens being demolded. The temperature gradient causes a differential expansion and shifting of the surface of the backcurve mold relative to the surface of the lens to lessen the adhesion therebetween to assist in separation of the molds, while leaving the lens in the frontcurve mold. The conductive heating probe includes a convex heating surface which contacts and is the same general shape as a concave surface on the backcurve mold, and can also include a compliant heat conductor to conform to the concave surface on the backcurve mold. In one embodiment, the apparatus includes a conductive heating probe assembly having an n x m array of conductive heating probes which contact each backcurve mold of an n x m array of molds assemblies positioned in a support pallet.

Title: Method and apparatus for the thermal bonding of a base part of a packaging with a cover film, and a method and apparatus for packaging contact lenses
Inventor: RITTNER PETER
IPC: B65B7/28
Filed: 1998-02-02
Granted: 2001-10-01
Abstract: In a method for the thermal bonding of a base part (3) of a packaging with a cover film (F), especially for the welding or sealing of a base part of a packaging for contact lenses with a cover film, the contact surface of the base part (3) facing the cover film (F) and the corresponding contact surface of the cover film (F) facing the base part are mechanically pressed against one another along a join. While the mechanical pressure is being generated along the join, heat is simultaneously caused to act on the join, so that the contact surfaces of base part (3) and cover film (F) are thermally bonded to one another along the join. For the purpose of generating the mechanical pressure and causing heat to act on the join there is used a contact plate (70) of low heat capacity which, during the thermal bonding, is pressed against the surface of the cover film (F) remote from the contact surface. The temperature of the contact plate is measured in the immediate vicinity of the cover film, and in the event of the measured temperature deviating from a predetermined tolerance range around a desired temperature, the temperature of the contact plate (70) is within a very short time adjusted so that it again lies within the predetermined tolerance range around the desired temperature.

Title: Method of dyeing fluffy yarn, bobbin yarn and on the warp dyeing machine using unit flow control
Inventor: WANG YOU-JENG
IPC: D06B23/24
Filed: 1998-02-04
Granted: 2000-06-01
Abstract: A method of dyeing fluffy yarn, bobbin yarn and on the warp dyeing machine using a unit flow control, comprises using an empirical formula to calculate the required unit flow rate per kilogram of natural or artificial fiber or a blending thereof (1/kg-min, amount of liquid flowing through per minute per kilogram of article-being-dyed) when a fluffy yarn, a bobbin yarn, or a warp yarn is dyed, such that the quality of dyeing (e.g. layer difference, granular difference, color difference and batch difference) could be within the control limit. The total weight of the articke-being-dyed per batch multiplied by the unit flow rate obtains a total flow rate value (l/min) which is the set value of the flow rate to the centrifugal pump of the dyeing machine so that the centrifugal pump can provide a real flow rate needed by the process, thereby reducing the costs in raw material and power while greatly increasing the quality of the dyed article.

IPC: G06F11/28
Filed: 1998-08-27
Granted: 2001-04-01
Abstract: A method of validating that a graphical display output of a given software application is consistent across respective operating systems. The method begins by capturing successive graphical display output frames at a given execution point in the software application on each of the respective operating systems. The pair frames are then processed to generate a delta value that masks graphical display output constructs for the respective that are time-invariant across the pair of frames. The delta values generated during each test run are then compared, preferably using a statistical analysis, to validate that the graphical display output of the given software application is consistent across the respective operating systems. The technique may also be used to validate the application across multiple execution runs in a homogenous computer system.
