Patent CA-2149657-A1 (CA)
Title: Compositions containing growth factors and antiplastic agents
Inventor: SAMS KAREN C
IPC: A61K39/36
Filed: 1994-09-29
Abstract: The intraocular use of combinations of lens epithelial cell growth stimulators (e.g., TGF-.beta.) and antimetabolites (e.g., mitomycin C) is described. The combination is applied to the capsular bag to prevent or retard the formation of secondary cataracts following cataract surgery. The lens epithelial cell stimulators activate DNA synthesis in dormant lens epithelial cells, and thereby make those cells susceptible to the antimetabolites. This enables the antimetabolites to suppress the proliferation of lens epithelial cells to a much greater extent, relative to the proliferation observed when the metabolites alone are utilized. The increased suppression of the growth of lens epithelial cells results in a significant improvement in the ability to prevent or retard the formation of opacities on the lens capsule (i.e., secondary cataracts).

Title: System and method for automatically recording television programs in television systems with tuners external to video recorders
Inventor: MANKOVITZ ROY J
IPC: H04N5/761
Filed: 1994-06-02
Abstract: A system capable of automatically recording television programs broadcast on different cable television channels. The system includes a cable box, a video recorder and a cable programmer. The consumer enters sets of channel, date, time-of-day and length commands ("CDTL information") or compressed codes representatives of such sets of commands into the video recorder. From each set of commands, subsets of date, time-of-day and length ("DTL information"") are stored in the video recorder's memory. At the same time or shortly thereafter, a subset of channel, date and time-of-day commands ("CDT information") from the same set of commands is transmitted to the cable programmer. The cable programmer and video recorder have independent control circuits to control certain aspects of the recording process according to the subsets of commands stored in their memories. The control circuits of the video recorder control the starting and stopping of recording while the control circuits of the cable programmer tune the channel on the cable box. Information is transferred from the video recorder to the cable programmer and from the cable programmer to the cable box via IR links or other remote control technique.

Ce système comprend un émetteur-récepteur relais, dans lequel les signaux provenant des terminaux sont convertis dans les deux sens au format des cellules de longueur fixe conformes au mode ATM, lorsque ces signaux ont un autre format. Une interface de transmission convertit dans les deux sens les signaux au format des cellules de longueur fixe conformes au mode ATM en signaux multiplexés par répartition dans le temps lorsque la transmission s'effectue vers l'amont, et fait la conversion inverse pour les transmissions vers l'aval, l'amont étant le sens d'acheminement vers l'interface de transmission et l'aval le sens d'acheminement vers les terminaux. De plus, le système effectue le transfert des signaux multiplexés par répartition dans le temps vers le commutateur. Selon un autre mode de réalisation, le système peut comporter au moins deux terminaux, chacun d'eux étant conçu pour émettre vers l'autre terminal et recevoir de celui-ci des signaux de différents formats; ainsi qu'un émetteur-récepteur relais programmable.

Inventor: ESSOP SALEAM
IPC: B01D43/00
Filed: 1996-01-26
Abstract: This invention relates to a separator device for the separation of fine particles from a contaminated liquid.

IPC: B23Q35/00
Filed: 1996-02-08
Abstract: A key cutting machine includes a cutter wheel, a key follower and a key positioning fixture for retaining a master key and a key blank in defined positions. Longitudinal and lateral displacement elements displace the cutter wheel and the key blank relative to each other.  First and second electronic position sensors generate cutter wheel longitudinal and lateral position signals which electrically define the position of the cutter wheel relative to the key blank blade.  A mode control system selectively operates the key cutting machine in either an analog mode where the bit notch pattern of a master key is mechanically traced and duplicated in the key blade blank or in a digital mode in which an electronically defined bit notch pattern is electrically duplicated in the key blank blade without reference to or tracing the master key bit notch pattern.
