Abstract: A system for providing advertisements with search results in response to a search query comprises a front end and an advertisement server. The front end is configured: to receive a search query; to send a first search request to a search server and sending a first advertisement request to an advertisement server, wherein the first search request includes the search query or information based on the search query, and wherein the first advertisement request includes the search query or information based on the search query and an indication that an advertisement response is not to be provided; to receive search results from the search server; and to send at least some of the search results to the advertisement server in a second advertisement request, wherein the second advertisement request includes an indication that an advertisement response is to be provided.

Abstract: A septum contains at least one internal chamber along the central axis of the septum. The chamber provides relief space into which the sealing sections of the septum can deform as a needle passes through the septum. Incorporation of the chamber reduces surface area contact and friction between the septum and needle, which results in reduced septum tearing and reduced production of particulate matter from abrasion.

Abstract: A septum containing a duckbill valve assembly includes a plurality of elastomeric ribs extending from the body of the septum to the duckbill valve assembly. When inserted into an injection port cavity, force generated by an interference fit between the body of the septum and the cavity is transmitted by the ribs to the duckbill valve assembly. The ribs are configured to reversibly collapse at a hinge point when a needle is inserted through the duckbill valve assembly and are spaced to assist in centering the needle in the duckbill valve assembly. The ribs reduce wear on the duckbill valve assembly by reducing the concentration of compressive forces at higher inlet pressures while maintaining sufficient compressive force to close the duckbill valve assembly at lower inlet pressures.

Abstract: Methods, systems, and apparatus include computer programs encoded on a computer-readable storage medium for selecting content. A method includes: receiving an initial request for content that is to be presented along with search results responsive to a search request; identifying one or more eligible content items from the candidate content items that satisfy the initial request; receiving information describing the search results; re-processing the initial request using the information including one or more of adding other eligible content items, removing one or more previously eligible content items, adjusting a quality score or a bid associated with one or more eligible content items, or re-ranking the eligible content items; conducting an auction based on ranked eligible content items; and selecting one or more content items from among the eligible content items based on the results of the auction and transmitting the selected one or more content items.

Abstract: A portable, artificial scrape tree having a secured game camera is provided for use in buck hunting. A method for hunting is provided consisting of anchoring an artificial scrape tree to the ground at a first location adjacent to a doe's bedding area and primary food sources and a buck's bedding area and food sources. Also provided is a new method for surveying an area of land, consisting of allocating a plurality of artificial scrape trees on the area of land being surveyed, with each artificial scrape tree being outfitted with at least one game camera for recording buck activity near the artificial scrape tree.

Abstract: A method of tracking and reporting the velocity of a hand-held paint spray gun. The object to be painted is placed in a room having one or more fiducial walls. A camera is installed on the spray gun, with its field of view toward the one or more fiducial walls. As the object is painted, the camera detects fiducials, calculates their current position, and compares current positions to previous locations to determine movement and velocity. The current velocity is compared to a stored target velocity, and audible or visible feedback is provided to the spray gun operator.

Abstract: A process for the extraction of a precious metal, such as gold or silver, from a sulphide ore or concentrate or other source material comprises subjecting the source material to pressure oxidation to produce a pressure oxidation slurry. The pressure oxidation slurry is flashed down to a lower temperature and pressure and is then subjected to a liquid/solid separation to obtain a pressure oxidation solution and a solid residue containing the precious metal. The solid residue is then subjected to cyanidation to extract the precious metal. The formation of thiocyanide during cyanidation is minimized or counteracted by effecting the cyanidation at an elevated oxygen pressure and a reduced retention time, such as 30 to 90 minutes. A method for the reduction of copper cyanide formation during cyanidation leaching is also provided.

Abstract: A process for the extraction of a base metal such as Ni, Co or Zn, from suiphide ore or concentrate containing copper and the base metal comprises the step of subjecting the ore or concentrate to pressure oxidation in the presence of oxygen and an acidic solution containing halide and sulphate ions to produce a product solution containing copper and the base metal. The product solution is subjected to a copper extraction process for recovering copper from the solution and the product solution containing the base metal after copper recovery is recirculated for recycled to the pressure oxidation to effect build-up of the base metal in the product solution. Preferably, a stream which is split from the product solution is treated for the recovery of the base metal.

Abstract: A filter for molten metal is an open-pored porous material comprising particles of refractory material embedded in and bonded together by a carbon matrix bonding material. The filter can be made by forming a porous article from refractory particles, e.g. refractory oxide, carbide or graphite, and a carbon-rich binder, e.g. tar, pitch or an organic (preferably aromatic) polymer that degrades to form carbon on pyrolysis, and then firing the porous article to generate the carbon matrix in which the refractory particles are embedded. The porous article is preferably made by coating a reticulated polyurethane foam with binder and refractory particles, and firing at preferably no higher than 800° C.
