Title: Tight pitch nozzle with individual valve gate control
Inventor: BABIN DENIS
IPC: B29C45/16
Filed: 2003-11-05
Abstract: An injection molding system is disclosed. The system includes a multiple valve gated nozzle. The flow through each valve gate is determined by individually operated valve pins. Each valve pin is independently controlled by a separate actuation unit. In order to achieve a tight pitch between the valve pins, the actuation units are placed in a stacked configuration, with the valve pin controlled by the upper actuation unit passing through the lower actuation unit. The valve pin of the lower actuation unit is offset from a center of the upper actuation unit to allow for the unimpeded passage of the valve pin from the upper actuation unit through the lower actuation unit.

Title: Systems and methods treating bone
Inventor: CANTU ALBERTO R
IPC: A61F2/44
Filed: 2002-09-10
Abstract: Systems and methods for treating bone employ an expandable body sized to be inserted into bone over a guide wire, without need of an access cannula, and undergo expansion in cancellous bone to compact cancellous bone. The systems and methods further include one or more other instruments sized to pass over the guide wire. The other instruments can comprise, e.g., a cannula, or a device for injecting material into bone. The systems and methods can make us e of a special guide wire assembly that includes a guide wire having an enlarg ed component or tip element on its distal end that can be used to engage the distal end of a bone treatment tool in response to a pulling motion on the guide wire. The pulling motion on the guide wire serves to withdraw the bone treatment tool. The enlarged component or tip element on the distal end of t he guide wire can enable the withdrawal of an inner centering body from an oute r cannula body after deployment. After withdrawal of the inner body, the outer body can be used, e.g., to guide a bone treatment tool into a bone, or to convey material into bone.

Title: Method to identify constituent proteins by peptides profiling
Inventor: EMILI ANDREW
IPC: G06F19/00
Filed: 2002-05-30
Abstract: This invention describes the use of peptide profiling to identify, characterize, and classify biological samples. In complex samples, many thousands of different peptides will be present at varying concentrations. T he invention uses liquid chromatography and similar methods to separate peptide s, which are then identified and quantified using mass spectrometry. By identification it is meant that the correct sequence of the peptide is established through comparisons with genome sequence databases, since the majority of peptides and proteins are unannotated and have no ascribed name or function. Quantification means an estimate of the absolute or relative abundance of the peptide species using mass spectrometry and related techniques including, but not limited to, pre- or post-experimental stable o r unstable isotope incorporation, molecular mass tagging, differential mass tagging, and amino acid analysis.
