Granted: 2006-06-06
Abstract: A method, apparatus and computer program product for reducing the data transmitted over an external communication link using the TCP protocol from a first application resident in a first computer and to a second application resident in a second computer. The method, apparatus and computer program product include establishing a first virtual socket in the first computer in response to each connection request by the first application for receiving request data originated by the first application. A first real socket in the first computer and a second real socket in the second computer are established to connect the first computer to the second computer over the external communication link and are maintained until the request data has been provided to the second application. In the second computer a second virtual socket is established for each connection request by the first application wherein the second virtual socket corresponds to a first virtual socket established in the first computer in response to a connection request by the first application. Request data associated with a first virtual socket is multiplexed onto the first real socket and transmitted over the external communication link utilizing the TCP protocol. The multiplexed request data is received from the external communication link by the second real socket and demultiplexed. The demultiplexed request data is provided to the corresponding second virtual socket which provides the request data to the second application.

Abstract: Split mechanical seal assemblies which include a pressurized fluid barrier and multiple concentric and axially aligned stationary seal rings. The stationary seal rings are in sealing relation with a rotary seal ring at their respective seal faces, and with the gland of the mechanical seal assembly, thereby forming an annular cavity for pressurized fluid to create a positive fluid pressure barrier across the seal faces when in sealing contact with each other. The axially and concentrically aligned stationary seal rings comprise an inner stationary seal ring and an outer stationary seal ring, and the area of the axially extending portion of the outer surface of the outer seal ring partially defining the annular cavity is greater than the area of the axially extending portion of the inner surface of the outer seal ring partially defining the annular cavity. The split configuration of the seal assembly facilitates quick installation, removal and maintenance of the seal assembly and its component parts. The seal assembly is also compact in design on account of the concentric and axially aligned stationary seal rings, permitting installation and maintenance of the assembly and its component parts under circumstances where space is limited. These benefits are provided without sacrificing the function benefits of a pressurized fluid pressure barrier as a supplement to the seal between the stationary and rotary seal rings.

Abstract: An elongated wedge shaped spline can be used for joining work pieces in a dovetail joint. It can be used in joining a work piece, such as molding in a dovetailed joint. A divider track having a base support and a pair of spaced apart flanges extending at a right angle from the front surface of the base support is first affixed to a surface. The wedge shaped spline is positioned between and in abutment with the upper portion of the spaced apart flanges. A fan shaped mortise on the back surface of a work piece is positioned over the wedge shaped spline between and abutting the upper portion of the spaced apart flanges.  Pressure is applied on the front surface of the work surface of the work piece for seating the work piece on the divider track, thereby forcing the wedge shaped spline between the flanges and spreading the flanges. The spread apart flanges engage the side walls of the fan shaped mortise for joining the work piece in a dovetailed joint with the divider track.
