Abstract: A method for improving the draining of aqueous humor in an eye of a living being and a device for widening the Schlemm's canal is described wherein a first incision is made in a lamellar section of the sclera to form a first scleral flap which is then folded upwards in the direction of the cornea, thereby creating a recess in the sclera. A second scleral flap is formed by incising a second lamellar section in the area of the recess and lifted upwardly in the direction of the first sclera flap, thereby exposing two opposite openings into the Schlemm's canal into which an expanding medium is injected into the Schlemm's canal; formation of a slitlike passageway connecting the aqueous humor-permeable Descemet-membrane with the subscleral space is realized by detaching the Descemet-membrane on the area of the Schwalbe's line by means of a slight pressure force; and subsequently, the first scleral flap folded back, after severance of the second scleral flap, for placement upon a support surface formed as a consequence of the incision of the second lamellar section. Subsequently, a viscous medium is injected into a subscleral space formed behind the first scleral flap and the first scleral flap is rejoined to the sclera.

Title: System and method for switching packets in a network
Inventor: SCHWARTZ STEVEN J
IPC: H04L12/56
Filed: 1999-07-01
Abstract: A switching node for transferring packets, each including a destination address, in a network includes a plurality of input port modules, a plurality of output port modules and a switching fabric, including a packet meta-data processor and a packet switch. Each input port module is connected to a communication link for receiving packets thereover, and each output port module is connected to a communication link for transmitting packets thereover. Each input port module, upon receiving a packet, buffers the packet and generates a meta-data packet therefore identifying the output port module that is to transmit the packet and packet identifier information, and provides it to the packet meta-data processor. The packet meta-data processor receives the meta-data packets generated by all of the input port modules and operational status information from all of the output port modules and for each output port module, processes the meta-data packets received from all of the input port modules in connection with the operational status information to determine whether the packet should be passed or dropped. If the packet meta-data processor determines that a packet associated with a meta-data packet is to be dropped, it will notify the input port module in which the packet is buffered, which, in turn, will discard the packet. On the other hand if the packet meta-data processor determines that the packet associated with the meta-data packet is not to be dropped, it will enqueue the meta-data packet for the associated output port module. Each output port module retrieves meta-data packets from its respective meta-data packet queue maintained therefor by the packet meta-data processor. For each meta-data packet retrieved by an ouput port module, the output port module will request that the input port module identified in the meta-data packet transfer the packet identified in the input port module thereto through the packet switch.  When the output port module receives the packet, it will transmit it over the communication link connected thereto.

Title: Dispersion of fine porous inorganic oxide particles and processes for preparing same
Inventor: CHAPMAN DAVID MONROE
IPC: C01B33/141
Filed: 1999-07-07
Abstract: A dispersion comprising fine porous inorganic oxide particles, e.g., silica gel particles, wherein the particles have a median particle size below three microns. The dispersed particles have a porosity after drying in which at least about 0.50 cc/g of pore volume is from pores having a pore size of 600 .ANG. or less as determined by nitrogen porosimetry. Embodiments prepared from silica gel have porosity after drying in which at least about 0.7 cc/g of pore volume is from pores having a diameter of 600 .ANG. or smaller. The particles of the dispersion also can be described as having viscosity derived pore volume of at least about 0.5 cc/g. The dispersion is prepared by forming a dispersion from inorganic oxides having sufficient rigid structure to maintain porosity after milling and drying. After the inorganic oxide is selected, it is milled to have a median particle size of 0.05 to about 3 microns. In embodiments in which stable dispersions of fine porous particles are desired without the addition of substantial amounts of dispersant, or if dispersions having a median particle size less than one micron are desired, the dispersion is created by, for example, centrifuging the milled slurry to obtain a settled phase and a supernatant phase in which the median particle size is in the range of 0.05 to about 1 micron. The supernatant phase is then separated from the settled phase to create the final product.
