Title: Model gun with automatic bullet supplying mechanism
Inventor: KUNIMOTO KEIICHI
IPC: F41B11/56
Filed: 1998-10-08
Granted: 2001-12-11
Abstract: A model gun with automatic bullet supplying mechanism comprises a pressure accumulating chamber from which a gas leading passage extends, a slider movable along a barrel structure, a pressure receiving portion fixed in the slider at the back of the barrel structure, a movable member provided with first and second inner spaces and arranged at the back of a bullet holding chamber, a passage connecting portion provided at the outside of the movable member for connecting the gas leading passage to the first and second inner spaces in the movable member, and a movable valve provided in the passage connecting portion. The movable valve is operative selectively, during a period in which the gas leading passage is connected through the passage connecting portion to the first and second inner spaces in the movable member, to cause gas derived through the gas leading passage from the pressure accumulating chamber to act through the first inner space in the movable member on a sham bullet in the bullet holding chamber and to shut off gas flow to the bullet holding chamber through the first inner space in the movable member from the gas leading passage so that the gas derived through the gas leading passage from the pressure accumulating chamber acts through the second inner space in the movable member on the pressure receiving portion to cause the pressure receiving portion to move back in company with the slider.

Title: Spring biased rotary air valve
Inventor: SMITH RODNEY F
IPC: F16K31/44
Filed: 1998-10-14
Granted: 2006-07-25
Abstract: There is provided a low profile valve assembly for controlling flow of air and the like. The valve assembly includes a housing defining inlet and outlet ports and a valve operator located within the housing. The operator includes a body portion seated in the housing with an axis of rotation and defining an internal passage with inlet and outlet ends. An actuator rotates the body portion a first predetermined distance to a fill position to allow flow through the internal passage and a second predetermined distance opposite the first direction to a vent position to allow flow to vent from the valve assembly through the outlet end. A spring extends from the valve operator adjacent the body portion between the axis of rotation and the valve housing. The spring extends partially about the axis of rotation to bias the body portion to an off position to substantially prohibit flow through the valve operator when the body portion is not being actuated to the fill and vent positions. The spring operates substantially within an internal space in the operator about the axis of Potation. The valve assembly includes an orifice to reduce volume flow through the valve assembly and an exhaust passage portion to reduce flow pressure between the inlet and outlet ends.

Abstract: Replication-competent adenovirus vectors specific for target cells and methods of use of such viruses are provided. These adenoviruses comprise a first adenoviral gene under control of a cell specific heterologous (i.e., non-adenoviral) transcriptional regulatory element (TRE) and at least a second gene under control of a second heterologous TRE, where the heterologous TREs are different from each other in polynucleotide sequence but functional in the same cell. The adenoviral gene can be, for example, a gene required for adenoviral replication.  The second gene can be, for example, a second adenoviral gene or a transgene, such as a gene which can contribute to cytotoxicity in the target cell. Adenoviral replication can be restricted to target cells in which the heterologous TREs are functional and thus, the adenovirus vectors can provide selective cytotoxicity to the target cells, particularly neoplastic cells.

Filed: 1998-04-03
Granted: 2003-06-03
Abstract: A wireless communication system facilitates communication within subscribing units within a respective service area, supports at least one communication protocol revision. The system communicates with a subscribing unit operating within a respective service area to determine the communication protocol revisions supported by the subscribing unit. Subsequently, the subscribing unit and base station communicate according to a supported communication protocol revision. The base station and subscribing unit may further communicate to indicate extended services supported by the subscribing unit and the methods of delivering the extended services to the subscribing unit.  The extended services may include caller line ID, message waiting indications and short message services among other extended services. In addition to a base station, the wireless communication system may include a mobile switching center that is in communication with the base station. The mobile switching center may include a visitor location register that records communication protocol revisions supported by the subscribing unit. In such construction, the visitor location register may also include records that indicate which extended services are supported by the subscribing unit as well as the protocols supported by the subscribing unit for delivery of the extended services. The base station may include a protocol capability indication unit while the subscribing unit may include an identification unit that, together, facilitate determining correct operation. A method of operation allows the base station and subscribing unit to communicate and operate according to common protocol revisions and to correctly deliver extended services to the subscribing unit.

Title: Quotation mechanism for service environments
Inventor: WEISS MICHAEL
IPC: G06Q30/00
Filed: 2000-05-05
Granted: 2007-03-27
Abstract: The present invention provides a quotation mechanism for service environments where the service level is negotiated. A client makes a request for a type, quality or volume of service. The service provider provides a response in the form of a quote. A quote binds the service provider to providing a service a t a specified price. The quote also contains parameters of type, quality, or volume of service that the service provider can provide at that price. The client, aft er evaluating the quote, can either accept or reject a quote. The client can al so obtain quotes from multiple service providers and enter a service contract with the service provider of its choice. This choice will not be based solely on price, but also on the levels of service quoted, since the service provider might not be able to supply the service at the requested level.
