Abstract: A rotation and air/abrasive delivery system for an abrasive material surface finishing system includes a rotating basket within the tub; a blast head connected with a compressed air source and an abrasive media source; a hinged connection configured to allow angular adjustment of the blast head into a desired angular position relative to the rotating basket and maintain the blast head in the desired angular position; a motor outside of the tub that is configured to drive rotation of the rotating basket; a bearing shaft connected with the motor and with the rotating basket, the bearing shaft being operable to transfer rotational force from the motor to the rotating basket; and a linkage assembly having at least one seal configured to isolate the motor from the abrasive media source within the tub. A method of retrofitting an abrasive material surface finishing system is also disclosed.

Abstract: A female terminal for an electrical connector may generally include a socket with an opening for receiving a male terminal, a first pair of contacts, a second pair of contacts, a pair of crimping members, and positioning tabs. The socket may be defined by a pair of opposing sidewalls, a top, and a bottom, at least in examples where the socket is generally rectangular. The first and second pairs of contacts may be disposed along the pair of opposing sidewalls, projecting at least partially into the socket configured to contact and exert substantially the same normal force on a male terminal that is inserted into the socket. The pair of crimping members can be utilized to secure a wire to the female terminal, and the positioning tabs may be utilized to secure the female terminal within the electrical connector.

Abstract: An interactive system enables users to generate and submit lists of items (e.g., products selected from an electronic catalog) for viewing by other users. The user-generated lists are selectively suggested to users of the system based (or based in part) on ratings of the user-generated lists. These ratings may, for example, be based on explicit ratings of the lists by users, and/or measures of how effective the respective lists are at driving purchases of items. In some contexts, the system may select one or more user-generated lists to present to a user based on a set of items purchased, viewed, or otherwise selected by the user, or based on the results of a search query submitted by the user.

Abstract: A facility for presenting information about new items, such as new items available via a web site is described. The facility receives a request for information submitted on behalf of an identified user. In processing the request, the facility accesses a set of items having effective times. The facility performs a first filtering process to eliminate items of the set whose effective times indicate that the items are not new. The facility performs a second filtering process to eliminate items of the set in which the user likely has a low level of interest. Subsequent to both the first and second filterings, the facility presents to the user information about each of at least a portion of the filtered items.

Abstract: A broadband RF Spectrum Transmitter combiner is duplexed with a Receiver splitter/multicoupler through a unique circulator/isolator configuration to provide a bi-directional radio input, unidirectional input at the receiver multicoupler to the radio and a unidirectional output from the radio to the transmitter combiner output. The circulator/isolator duplexer circuitry may be configured for any RF frequency band and in conjunction with the use of a same frequency band transmit combiner and receiver multicoupler provide the cohabitiation of mobile radios with isolation is excess of 60 dB. The multiple ports may be connected to multiple radio units, each with a different frequency, and combined and connected to a transmit antenna and a receive antenna. The duplexer-combiner configuration is used then to combine the bi-directional antenna port on the radios into a pair of antennas spaced apart from one another as to not degrade the isolation provided by the duplexer-combiner configuration.

Abstract: The present invention provides methods for isolating biological target materials, particularly nucleic acids, such as DNA or RNA or hybrid molecules of DNA and RNA, from other substances in a medium using silica magnetic particles. The methods of the present invention involve forming a complex of the silica magnetic particles and the biological target material in a mixture of the medium and particles, separating the complex from the mixture using external magnetic force, and eluting the biological target material from the complex. The preferred embodiments of magnetic silica particles used in the methods and kits of the present invention are capable of forming a complex with at least 2 ?g of biological target material per milligram of particle, and of releasing at least 60% of the material from the complex in the elution step of the method.
