Granted: 2003-09-23
Abstract: An upper plate includes a depending truncated cone member that supports a ball. A lower plate supports an upstanding truncated cone member that supports a cup socket that the ball is press fitted into. The cup socket embraces the ball to a line above the middle diameter of the ball to prevent the ball from coming free of the socket in normal use. A number of wires form a repeating X pattern between the upper and lower plates about their perimeters and serve to restrain rotational motion. The upper plate incudes upwardly projecting spikes and the lower plate includes downwardly projecting spikes. The upper and lower plates each include two anchoring brackets that project outwardly to lie adjacent to an upper and lower spinal disc, and that are fastened to the discs by bone screws. The spikes further anchor the vertebral body prosthesis in the adjacent spinal discs.

Title: Use of transmission control protocol proxy within packet data service transmissions in a mobile network
Inventor: HERLITZ ANDERS
IPC: H04L12/66
Filed: 1998-12-08
Granted: 2008-10-07
Abstract: A method and apparatus for generating a TCP packet connection (160) between a remote host (40) on a first network (Internet/Intranet) and a mobile station (30) on a mobile network is disclosed. The process initially involves performing a three-way handshake routine (100, 105, 110) between the remote host (40) and a gateway packet mobile switching center (55) of the mobile network to establish the validity of a TCP packet connection request. During the handshake routine transmissions (100, 105, 110) from the remote host (40) are buffered by the gateway packet mobile switching center (55). A second three-way handshake routine (145, 150, 155) is then carried out between the gateway packet mobile switching center (55) and the mobile station (30) using the buffered transmissions to complete a TCP connection (160) between the mobile station (30) and the remote host (40).
Patent CA-2316976-C (CA)
Title: Osmotic delivery system with membrane plug retention mechanism
Inventor: AYER RUPAL
IPC: A61K9/52
Filed: 1998-12-15
Granted: 2009-02-17
Abstract: An osmotic delivery system has a membrane plug retention mechanism which can also be used to control the delivery rate of a beneficial agent from the osmotic delivery system. The osmotic delivery devi ce includes an implant capsule containing a beneficial agent and an osmotic agent. Holes are formed along a side wall of the implant capsule at an open end of the capsule. When the membrane plug is inserted into the open end of the capsule the membrane material swells into the holes in the capsule side wall creating a large frictional force which prevents expulsion of the membrane plug. A beneficial agent delivery rate of the osmotic delivery system is controllable by varying the size and number of the holes to change the amount of exposed surface are a of the membrane plug. An increase in the surface area of the membrane plug exposed to the exterior environment causes a corresponding increase in the liquid permeation rate of the membrane and thus, increases the beneficial agent delivery rate.

Title: Calcium fortification of cheese
Inventor: MEHNERT DAVID WEBB
IPC: A23C19/076
Filed: 2001-03-26
Granted: 2004-11-23
Abstract: The present invention provides a method of making flavorful, organoleptically pleasing natural cheese containing a significant level of a calcium supplement. More specifically, the calcium supplement is a mixture of calcium sulfate and tricalcium phosphate. By using a mixture of calcium sulfate and tricalcium phosphate the bitterness normally associated with calcium sulfate and the graininess normally associated with tricalcium phosphate are surprisingly essentially eliminated. The use of these particular calcium sources allows for significant levels of calcium to be incorporated without requiring excessive levels of the calcium compounds. The calcium supplements of the present invention can be used in, for example, cottage cheese, process cheese, and natural cheeses such as, for example, Cheddar cheese, Colby cheese, Monterey Jack, Havarti cheese, Muenster cheese, Brick cheese, Gouda cheese, Mozzarella cheese, and mixtures thereof.

Abstract: A support frame assembly for use in the manufacture of furniture, including a pair of frame members, one or more support springs and spring anchors for coupling the springs to the frames. The springs function as a load absorbing resilient base for padding and/or cushioning used in the seating construction. The spring anchors are used in securing each end of the springs under tension to a frame member. Each spring anchor is formed as a generally P- shaped clip, having a flange portion which merges into and is integral with a loop portion which defines a bore extending therethrough. The loop portion is formed as a continuous fully closed loop to provide the anchor clip with increased structural integrity and to better resist deformation upon the application of load forces to the spring. The flange portion is secured directly to the frame member in a position so that the loop portion projects forwardly past an edge of the frame member closest towards the other opposing frame member.
