Abstract: The present invention provides a suture package and packaging method which ensures rapid access to sutures, one at a time, from a suture package which is easy to handle and store. Each suture is readily located in an advantageous position in the package, to be grasped by a needle holder, without the possibility of pulling unwanted sutures from the package, or the need to fumble through a bunch of needles to ensure that a single suture is obtained. This is done by providing a suture package, comprising a panel or panels having an open window to expose the needles, and a plurality of raised support elements on at least one side of the panel, which elements support a suture in conjunction with the panel, the support elements being arranged to permit withdrawal of a suture from the package by pulling one end of the suture in a direction parallel to the plane of the panel. The needle window opening is located on the top edge of the package, exposing the needles in the opening, and showing the number of sutures available, as well as allowing access to the needles. Preferably, the suture package also employs at least one panel which has support elements for supporting sutures on each side of the panel. Preferably, the panels comprise separate needle window openings for the sutures on each side, and those needle window openings are separated from each other, so that the withdrawal of the suture will withdraw only one suture and in the assembled package, the windows on each panel line up with each other.

Abstract: A network provides users with a simple and secure way of establishing communication sessions with other users or services, running either over IP networks or other networks, e.g., PSTN. In a sense, the network can broker communication services between two or more users (e.g., people) and/or services. A plurality of different clusters of servers is provided, and each of the clusters may be linked together. In certain embodiments, each cluster includes multiple servers. Users are registered within some specific cluster and given a unique system/network ID. In certain embodiments, messages are not sent directly between users, but instead through at least one intermediate routing service (RS) provided on a server of one of the users. Thus, in certain embodiments, a user may hide or mask his/her personal information from other users even when communicating with them. In certain embodiments, a user may establish a communication session with another user without knowledge of the client device (e.g., PC, mobile phone, etc.) being used by the other user; as the network arranges for communication (e.g., text chat session, voice chat session (PC to PC, PC to PSTN, or PC to mobile phone), web conference, or pages (PC to PC, PC to SMS)) between the users regardless of the client device being used by the called user. Thus, the network enables any of the above communication services between users, and the initiating user need not know whether the other user is currently online via his/her PC or may instead be reached via pager or mobile phone.
Patent JP-2003520119-A (JP)
IPC: B01F23/47
Filed: 2000-04-25
Abstract: A counterbalanced, dual submarine-type liquid mixer provides a pair of counterbalanced mixing devices that move at opposing ends of a balance bar suspended above the surface of a liquid to be mixed. The bar is able to pivot so as to vertically move its ends alternately between a raised and a lowered position in such a manner that when one of the mixing devices is in a raised position in the liquid, the other of the mixing devices is in the lowered position and each of the two mixing devices tends to counterbalance the other. Each mixing device is buoyed upwardly in the liquid by the buoyant force of a gas captured below a concave surface of the mixing device and also by the negative buoyant force of the other mixing device when it has exhausted its buoyant gas. Alternately, each of the mixing devices, on its downward stroke is moved downwardly by its own weight (negative buoyancy) and by the buoyant action of the other mixing device which moves simultaneously on its upward stroke. Buoyant gas is injected and removed from under the mixing device's concave surface by a gas conduit channel integral with a supporting rod extending from the balance bar. The mixing device, in an alternate embodiment, uses a cable for interconnecting dual rigid caps or one cap and a counterweight to accomplish identical objectives.
