Abstract: An apparatus and method for automatically molding contact lenses from a polymerizable hydrogel comprises: a transport device for transporting a plurality of contact lens molds comprising first and second mold halves to and from a plurality of stations including a first automated station for receiving a plurality of first mold parts and depositing in each first mold part a predetermined amount of a polymerizable hydrogel; a second automated station for receiving the plurality of first mold parts and assembling each first mold part with a second mold part, under vacuum, to prevent entrapment of air between the mold parts; and, a procure station including a device for clamping the first mold half against the second mold half for a predetermined pressure and time to define a contact lens mold cavity and to remove any excess hydrogel from the cavity. The assembled first and second mold halves are further transported to a radiant energy source for polymerizing the polymerizable hydrogel in each mold cavity after the first and second mold halves are clamped together. Finally, the mold assembly having the polymerized hydrogel therein is transported to an automated demolding station for removing the second mold part and any excess hydrogel from the first mold part and the molded contact lens.

Abstract: A method of and apparatus for tracking data associated with a load being conveyed on a belt conveyor (12) between a source station (16) including a source station load sensor (18) and a destination station (20) including a destination station load sensor (22) includes the steps of: generating a data record for the load at the source station, loading the data record into a programmable controller (C) for controlling the conveyor, generating a pulse signal having a number of pulses directly proportional to the travel of the belt conveyor (12), establishing an expectation window indicating expected arrival of the load at the destination station (20), establishing a distance field for the load using the smaller of the distance between the load and any preceding load on the belt conveyor (12) or the distance between the source and destination load sensor (22), sensing the leading edge of the load by the destination station load sensor (22), comparing the distance between the source and destination load sensors (18, 22) and detecting any slippage of the load on the belt (12) and updating the data record in the controller (C) based on the detected load slippage to coincide with the actual position of the load on the conveyor (12) at the destination station (20).
Patent CA-2156955-C (CA)
Title: Lamination between plastic resins to cement
Inventor: HISCOCK DONALD R
IPC: B28B19/00
Filed: 1995-08-25
Granted: 2006-07-11
Abstract: A shelled structure is composed of a resinous plastic layer that is bonded to a hydraulic cement layer by the presence of preformed wire, silica sand or chopped glass fibres at the interface. Set into the resin layer while it is still tacky the wire, sand or glass particles bond readily to both the resin and cement. A wire reinforcing mesh or matrix within the cement layer improves its strength and stability. Wire stubs set into the resin layer may be used to locate the wire matrix. Bonding is improved when the resin wire is in the form of a corrugated grid with part of the grid embedded in the resinous plastic layer. Bonding is further improved when a wire grid is used as the coupling agent in combination with sand particles or chopped glass. Alternately, these latter components may be used without a wire grid. Panel strength is improved when the embedded portion of the wire is overlaid with fibre reinforced resin.

Filed: 1994-09-28
Granted: 1999-02-02
Abstract: A process for removing perchlorate ions from waste water using KCl is disclosed. In the process, waste perchlorate is concentrated by water evaporation in a stripping tower. Ammonia and volatile organics are removed during the concentrating step. Potassium chloride (KCl) is added to the concentrated perchlorate solution to form potassium perchlorate (KClO4), and the reaction mixture is cooled to effect crystallization of the potassium perchlorate. The crystallization liquor is removed by centrifuge or filter press and may be further treated as part of an overall waste water treatment system.

Patent CA-2209580-C (CA)
Title: Scintillation crystal modules and methods of making the same
Inventor: HUTH SCOTT T
IPC: G01T1/164
Filed: 1997-07-04
Granted: 2000-09-05
Abstract: The invention provides a scintillation crystal module having an epoxy seal which has a coefficient of thermal expansion which is substantially the same as the backcap of the gamma camera. Among the suitable epoxy systems, the CTE of the epoxy could be modified somewhat by choosing a different catalyst or by adjusting the resin:catalyst ratio. The presently preferred epoxy system is a STYCAST R 2850 FT system available from W.R. Grace & Co. Using "catalyst 9" or "catalyst 11" from that system, a CTE of approximately 17.33x10-6 to approximately 19.4x10-6 in/in°F can be easilyachieved. It has been discovered through analysis using FEA that an epoxy with a CTE in the range of 9.0 to 20.0x10-6 in/in°F provides satisfactoryresults in preventing seal separation during +40°F temperature cycles. A method of making a scintillation crystal module according to the invention includes the preparation of an epoxy seal having a coefficient of thermal expansion which is substantially the same as the backcap of the module, and assembling the seal, backcap, glass, and crystal in a conventional manner.

Title: Vacuum seed metering mechanism
Inventor: JOHNSON DONALD T
IPC: A01C7/04
Filed: 1997-08-19
Granted: 2002-07-16
Abstract: A suction-type seed metering apparatus operably arranged in combination with the seed storage hopper.  The seed metering apparatus comprises a disc vertically mounted with driven rotation about a fixed rotary path of movement and having a circular role of apertures adjacent to peripheral to disc.  A housing is arranged in seed receiving relation relative to the seed hopper.  The housing has its interior divided by the disc into two adjacent enclosures.  One enclosure at least partially defines a chamber for seeds and opens to the seed hopper.  The other enclosure extends at least partially around the path of movement of the disc apertures and constitutes a vacuum chamber having leading and trailing ends with an opening leading to the chamber intermediately leading and trailing ends.  The trailing end of the chamber is arranged adjacent to seed drop area from whence seeds gravitationally fall for deposit in a furrow.  A salient feature of the present invention concerns the provisions of a series of openings arranged proximate to the seed drop area for enhancing the release of seeds from the disc of the metering apparatus.  The openings defined in the housing of the seed metering mechanism allows atmospheric air to enter into the housing thereby eliminating the suction or draw of air through the housing.  Thus, the seeds are permitted to freely and gravitationally fall from the seed discharge area without being rearwardly drawn under the influence of a vacuum pressure.
