Title: Automatic web splice control system - has roll radius and cross section gauged to compute web length drawn
Inventor: CLIFFORD JOHN W
IPC: B65H26/06
Filed: 1976-06-23
Abstract: The automatic web splice control system determines when an expiring roll of web reaches a preselected splice radius by sensing when the web roll has diminished to preset first and second radii. Then the system computes the roll cross-sectional area between the second radius and the preselected splice radius divided by web caliper to determine in advance the web length that will be drawn. Commencing at the second radius, the system then measures the amount of web drawn from the roll and when that amount equals the precomputed web length, the system generates a splice signal indicating that the roll has diminished to the preselected splice radius.

Title: Appareil perfectionne pour effectuer le transfert de l'oxygene dans le sang et l'enlevement du gaz carbonique de ce sang a travers une membrane microporeuse
IPC: A61M1/16
Filed: 1977-10-21
Abstract: L'invention décrit un appareil du type poumon artificiel pour améliorer simultanément le transfert en masse, à travers une membrane microporeuse, de O2 vers le sang et de CO 2 du sang. On améliore ce transfert en soumettant l'écoulement du gaz d'oxygénation sur la membrane à des pulsations. Cela évite la diminution progressive de la vitesse de transfert de CO2 (qui se produirait, sinon, en cas d'écoulement régulier) et cela permet de maintenir à un niveau acceptable ce transfert. L'appareil est applicable lorsque les poumons d'un patient ne peuvent jouer leur rôle, par exemple pour la chirurgie à coeur ouvert (le sang du patient étant pompé vers un circuit extracorporel comprenant un oxygénateur).
