Patent CA-2058409-A1 (CA)
Title: Intraocular lens and hot stamping method of manufacture
Inventor: FOGARTY TERRY M
IPC: A61L27/00
Filed: 1991-12-23
Abstract: A method for manufacturing an intraocular lens from a cell cast sheet of high molecular weight polymethylmethracrylate (PMMA). A lens blank 30 having a lens generation area 31 with a surface contoured to correspond to the desired contour of the finished lens 10 is machined from the sheet of PMMA to a predetermined precompensated size larger than desired to accommodate normalizing shrinkage. The lens blank 30 is normalized by heating the blank in a vacuum oven. The vacuum is released from the oven by introducing dry nitrogen. A stamping die 54 is provided. An optical embossing surface 56 of the stamping die is contoured as a physical negative of the lens generation area 31 and bears a physical negative of the desired optical surface structure of the lens, such as a multifocal diffractive zone plate 18. The embossing surface 56 of the stamping die 54 is forced into engagement with the surface of the lens blank 30 at a predetermined stamping pressure and for a predetermined stamping dwell time. Sufficient heat or ultrasonic energy is applied to the lens generation area 31 of the lens blank 30 to heat the lens generation area to a temperature between the glass transition temperature and the melt temperature of the polymer, and emboss the surface structure onto the lens generation area, The embossing surface 56 of the stamping die 54 is removed from the lens blank 30 following the expiration of the stamping dwell time.

Abstract: A B S T R A C T       The  invention  refers to  a  sensor  based  electronic system  to  be  used  in  bowling  houses  and  a  miniature minibowling  system.   The  sensors  detect  and  process  the information for each  PIN,   first   or   second   throw   (or delivery), sweep mechanism, cups, faul  line, traveling time of the ball from the throw until it reaches the PIN area for each lane, an interface connects the sensors to a computer that  calculates  each  player  score,  per  lane,  and  also controls the bowling house  illumination  system,  the motors of the mechanisms per lane as well as the cycle.  An inter-face communicates the computer to a sensor selection circuit. Several throw, faul, table,  sweep, cup, pin  and pine-apple sensors  are  presented,  taking  into  consideration  all  the sensors as an entity called "sensor based electronic system for minibowling systems and bowling houses"  Each of the ten holes located in every  lane table,  has  its  respective pin sensor  located  in  the  center  position  of  each  pin.  Each sensor has an emitter and receiver, (or an array of these), per hole, detecting a valid position pin event.   The exter-nal illumination system plays a vital role in this process.

Abstract: ABSTRACT The present invention is directed to a machine for closing and sealing an article, such as a box or carton, as it is driven through the machine. Specifically, upper and lower taping heads are provided for applying lengths of tape to the bottoms and tops of the boxes. The upper box flaps are also preferably folded by the machine of the present invention by a folding mechanism including a ski for folding the leading minor flap, a kicker for folding the trailing minor flap, and shaped rods for folding the major side flaps after the minor flaps are folded. In accordance with the present invention, the upper head assembly is advantageously adjustably connected to the machine so that proper leveling of the upper taping head and the folding mechanism can be assured. Moreover, such adjustment can be redone at any time thereafter as needed as affected by working conditions over time. Additionally, the subject machine includes a control system which uses only a minimum number of control sensors, namely two control valves, to control both the kicker and a gating mechanism effectively while permitting easy operator adjustment and machine versatility.
