Patent number: 5535375Abstract: A computer system manages files shared by first and second heterogeneous clients. The first client exhibits a first protocol such as SMB and the second client exhibits a second, different protocol such as NFS. A first protocol converter receives requests from the first client to create, read and update the files, and converts the requests to corresponding requests exhibiting a common protocol. A second protocol converter receives requests from the second client to create, read and update the files, and converts the requests to corresponding requests exhibiting the common protocol. A file manager is common to both clients and both protocol converters, receives the converted requests exhibiting the common protocol and executes the requests in a name space and data area which are both common to the first and second clients. The name space stores names of the files and the data area stores the files.Type: GrantFiled: October 11, 1994Date of Patent: July 9, 1996Assignee: International Business Machines CorporationInventors: Marc M. Eshel, Guerney D. H. Hunt, Donald N. Jones, Christopher Meyer, Frederick A. Schwartz

Patent number: 5156281Abstract: A bracketless extension rod includes a locking mechanism for holding the rod in place between two opposing support surfaces. The rod includes an inner rod section telescopingly fitted within channel means formed on a outer rod section. The locking mechanism includes a locking plate slidably received within the channel means and a tang means affixed to the locking plate. An extendable lever mechanism is attached to the inner rod section and to the locking plate. The tang permits the rod sections to move only in the direction of extension of the rod by engagement with opposing walls of the channel means. When extended, the lever mechanism places the rod in compression between two opposing supporting surfaces.Type: GrantFiled: March 22, 1991Date of Patent: October 20, 1992Assignee: Zenith Products Corp.Inventor: Frederick Schwartz
