Title: Highly radiopaque polyolefins and method for making the same
Inventor: WALKER JEFFREY
IPC: C08J3/20
Filed: 1998-08-07
Granted: 2009-12-29
Abstract: In accordance with the present invention there is provided a method for making a highly radiopaque polyolefin compound, wherein the radiopaque material in said compound is substantially uniformly dispersed and held within a polymer matrix. During the method one first heats an amount of polyolefin, preferably low density polyethylene, to at least its melting temperature. The amount of polyolefin is equal to at least 10% by weight of the compound. Then an amount of radiopaque metal powder is added to the polyolefin. The amount of radiopaque metal is equal to up to 90% by weight of the compound. The metal powder is preferably tantalum, tungsten, gold or platinum. Thereafter, an amount of a dispersing agent is added to the polyolefin to form a mixture. The amount of dispersing agent is equal to at least 0.2% by weight of the compound. The dispersing agent is preferably zinc stearate, aluminum stearate or calcium stearate. Lastly, the mixture is mixed and cooled below its melting temperature to form the compound.

Title: Method for making a product to be extruded, and an extruder
Inventor: KIRJAVAINEN KARI
IPC: B29C48/90
Filed: 1997-04-04
Granted: 2005-03-01
Abstract: The invention relates to a method for making a product to be extruded, and an extruder. The extruder comprises at least two conical stators (1, 2) and at least one conical rotor (3) placed rotatably between the stators. The extruder further comprises supply conduits (6, 7) for feeding the material to be extruded separately into the exterior and interior of the rotor (3). Each supply conduit (6, 7) is provided with a separately adjustable feeding device (9, 10) by means of which the amount of the material flow to be supplied can be adjusted. In such a case, the degree to which the space between the rotor (3) and the stator (1, 2) is filled and the amount of the heat generated by the friction can be regulated. Further, the ratio of the material flows in the different supply conduits (6, 7) determines the ratio of the thicknesses of the layers obtained. Therefore, the method and apparatus according to the invention make it possible to regulate the properties of the final product easily and in several different ways.

Title: Mobile furnace facility
Inventor: PURCELL JOSEPH
IPC: F27D99/00
Filed: 1998-12-10
Granted: 2004-03-23
Abstract: The present invention is a multi-faceted furnace apparatus. The apparatus has a furnace system, an electrical system, a positioning system and control unit. The furnace system has a set of movable electrodes, and at least two pour configurations, to transform a solid material into a molten state. The electrical system provides the electrode with a predetermined, yet changeable type of regulation, current, voltage, impedance, power, and/or imbalance of current. While the electrode positioning system moves the electrode, this movement determines if the electrode is properly positioned for the furnace to be an open arc system, a submerged resistance system, or submerged arc system. The above systems are monitored by the control unit. There by the furnace system, the electrical system and the positioning system can all be altered to achieve the most efficient and cost saving method to transform the solid material into the molten state.

Abstract: A mig welding gun has a handle with a longitudinal centerline and a hole with an axis transverse to the centerline.      A trigger is received in the handle for rotation about an axis perpendicular to and offset from the hole axis. A spring biases the trigger to a released position whereat the gun is off.      Applying a squeeze force to the trigger rotates it to a depressed position whereat the gun is on. A pin is slidable in the trigger to engage the handle hole when the trigger is in the depressed position. Removing the squeeze force while the pin engages the handle hole locks the trigger in the depressed position. Momentarily reapplying the squeeze force to the trigger causes the pin to disengage from the handle hole and enable the trigger to return to the released position. In a modified embodiment, the pin is engageable with a chap inside the hole.

Abstract: A method of making a metal bonded, abrasive tool uses a perforated stencil to place abrasive parcels in a pattern on the cutting surface of the tool. The stencil is placed against the tool preform so that the perforations define cavities. Metal brazing composition in the form of a paste is packed into the cavities and the stencil is removed to leave discrete parcels of brazing paste tacked to the cutting surface. Abrasive grains are deposited onto the paste particles and fixed in place by firing the preform at brazing conditions. The abrasive grains thus are precisely positioned and spaced apart on the cutting surface by abrasive free channels which are defined by the web of the stencil. The abrasive free channels provide paths to facilitate flow of coolant material and swarf particles at the cutting zone. The method can include initially placing the brazing paste parcels onto a resilient, transfer medium and subsequently transferring the parcels onto the preform cutting surface. This method is particularly useful for depositing an abrasive pattern on a non- planar or highly curved tool surface. In another contemplated variation of the invention, the abrasive grains are premixed with the brazin g paste prior to filling the cavities.

Granted: 2009-09-15
Abstract: Methods and apparatus for identifying associated key words (1035) in a data set (1000). Associated key words are identified by a parser (1020) which firstly operates to extract key words from a data set (1000). These key words are then analysed by the parser (1020) to identify which key words, if any, have an association as determined by a predefined set of rules. These rules are grammatical and include, for example, two keywords both being nouns that occur one after the other without intervening low value words. A similar rule applies to nouns followed by verbs but does not extend to verbs followed by nouns. These rules allow terms and phrases such as "information technology" and "wide area network" to be identified as associated key words (1035) rather than as individual and unrelated key words.
