Title: Volumetric infusion pump
Inventor: HARRIS MARK
IPC: A61M5/142
Filed: 1997-03-21
Abstract: A medical infusion pump is disclosed which provides for greatly improved accuracy in the delivery of medica-ments to a patient. Among the various features included in the instant invention is a pumping body which serves to deform and reform a tube so as to maintain the initial cross section thereof and thereby preserve the output accuracy of the pump. Also disclosed with regard to the pumping body is a wholly mechanical synchronization of the pump-ing body and valves associated therewith and coactive with the aforementioned synchronization a mechanical lineariza-tion of output of the pumping body per each pumping cy-cle. Additionally, several features which serve to enhance the utility of the instant invention are also included therein among which is an associated assembly operative to auto-matically load or disicad a tube or IV set into or out of the pumping body. Associated with the assembly operative to automatically load or disload a tube and disclosed herein is an assembly operative to selectively open or close a slide clamp associated with the tube in such a way as to ensure that the tube is occluded such that in combination with the valves associated with the pumping body, a condition of free-flow of medicament is never realized. Additionally disclosed are sensor housings adapted to measure various quantities associated with fluid flowing through the tube wherein the housings arc with associated components adapted to achieve a substantially normal orientation with respect to the sidewall of the tube and in the achieving of such normal orientation, expressing art essentially zero elastic stress gradient across the tube.

Title: Process for adjusting the hardness of fischer-tropsch wax by blending
Inventor: RYAN DANIEL FRANCIS
IPC: C10G73/00
Filed: 2001-03-13
Abstract: A wax blending process is disclosed which retains the desirable properties o f a Fischer-Tropsch wax, while adjusting the hardness of the wax to within a desired range. The invention utilizes a synergistic effect between hard virg in Fischer-Tropsch wax and softer mildly isomerized Fischer-Tropsch wax in a blending process which allows the artisan to adjust the hardness of a wax product to within desired ranges. The process involves passing a Fischer- Tropsch wax over a hydroisomerization catalyst under predetermined condition s including relatively mild temperatures such that chemical conversions (e.g.,  hydrogenation and mild isomerization) take place while less than 10 % boilin g point conversion (hydrocracking) occurs, thus preserving overall isomerized wax yield. At least a portion of the resulting isomerized wax is then blende d with untreated hard virgin.

Abstract: The present invention is essentially a method and system for leaving an d retrieving messages at specific coordinate way points within a commercial mobile radio service (CMRS) provider network. Users carry or transport interface devices for communicating over the network and are able to record and view messages at specific coordinate locations while traveling in the network. The location o f the device is calculated by the device or by the network while the device is powered on and in within the physical boundaries of the network, or through a combinati on of both. Messages can be made available to network subscribers when their interface devices come within an area centered about a physical coordinate location. Personalized messages can also be left by subscribers at any coordinate poin t within the boundaries of the network. The invention can also be used to facilitate access of information about an asset when a technician comes within a physical proximi ty threshold relative to said asset.
