Title: Variable power intraocular lens with astigmatism correction
Inventor: WILEY ROBERT G
IPC: A61F2/16
Filed: 1991-09-03
Abstract: An intraocular lens has a flexible lens body (34) formed from optically clear material surrounded by an outer ring (36) which is sensitive to an external force. Utilizing the external force, the shape of the outer ring (36) can be changed to elongate the lens body (34) along an axis for correcting astigmatism, or to change the lens power by altering the lens's spherical shape or curvature. Attached to one of the lens body (34) and the ring (36) are actuator bodies (38) of ferromagnetic material. An adjustable focus lens apparatus includes a transparent lens body (34) and a rigid outer ring (40) extending about the lens body periphery and micromotor devices (38) spaced equally about and coupled between the ring (40) and the periphery (34). Each micromotor device (38) is responsive to an externally generated control signal for selectively changing the circumference and/or axial position of an association portion of the periphery to adjust the lens for power and astigmatism correction.

Title: Procede de regeneration de l'acide d'accumulateurs au plomb
Inventor: SPITZ ROBERT A
IPC: B01D11/04
Filed: 1990-11-19
Abstract: La présente invention décrit un procédé d'extraction et de filtration pour enlever les impuretés métalliques de l'acide utilisé dans les batteries d'accumulteurs au plomb. Il en résulte un acide de batterie récupéré dont la performance dans des batteries neuves est très bonne et qui permet d'éviter les coûts et les risques pour l'environnement que comportent les méthodes actuelles. Dans une application préférée, la présente invention décrit un procédé de régénération de l'acide décapant utilisé lors de la récupération effectuée. Dans le processus d'enlèvement des impuretés par extraction de l'acide de batterie, l'extractant se charge d'impuretés et perd son efficacité. On peut régénérer l'extractant en le mettant en contact avec un acide décapant. On fait appel à un procédé de réduction pour régénérer l'acide décapant de sorte qu'on puisse l'utiliser de façon répétée. Par le recyclage de l'extractant et de l'acide décapant, le procédé de la présente invention permet d'augmenter l'efficacité de la régénération de l'acide de batterie en produisant un acide de batterie récupéré dont la performance dans les batteries neuves est très bonne et qui permet de réduire substantiellement les résidus polluants dans la régénération de l'acide de batterie.

Title: Papermaking apparatus including baffles
Inventor: EVENS DAVID A
IPC: D21D5/26
Filed: 1993-11-10
Abstract: PAPERMAKING APPARATUS INCLUDING BAFFLES               ABSTRACT OF THE DISCLOSURE    A  papermaking  deaeration  apparatus  including  a receiving  chamber,  and  a  plurality  of  cleaning  and deaeration wings extending therefrom.  A baffle is provided in the chamber of the receiver proximate the opening of each wing which communicates deaerated paper stock into the receiver  chamber.    The  baffles  redirect  downrushing deaerated paper stock such that it  is dispensed  in a "knifing" shape into the pool of paper stock contained in the chamber of the receiver.   Hence, standing waves and splashing in the pool of paper stock in the receiver is reduced.  The static pressure head created by the pool of paper stock is more uniform such that fluctuations in the static head are reduced.  Mechanical  vibrations which can reach the paper machine headbox and the primary cleaner supply pump are reduced such as the quality, consistency and caliper of the paper manufactured by the headbox is improved.  Further, reprocessing of deaerated paper stock which overflows a weir residing in the chamber of the receiver is also reduced.  Consequently, the cleaner supply pump is operated at a considerably lower flow, away from cavitation.    As  a  result,  consumption  of  deaeration chemicals  is  reduced.   Hence,  the overall  papermaking deaeration apparatus is more efficient.  Each baffle has a concave surface facing inward towards the wing chamber to cause conversion of the downrushing deaerated paper stock into a wide thin knife shape before entering the receiver chamber.   The deaerated paper stock is deflected by the baffle downward into the receiver chamber below the surface of the pool.
