    • A nozzle is provided for use during a process for cold-dynamic gas spraying a powder material onto a bore surface. In one embodiment, and by way of example only, the nozzle includes a tube and a coating. The tube is configured to direct the powder material to the bore surface and has an inner surface, an axial section, a radial section, and a bend. At least a portion of the inner surface of the axial section defines a converging/diverging flowpath, and the axial section and the radial section are disposed at a predetermined angle relative to one another and include the bend disposed therebetween. The coating is disposed on at least a portion of the tube inner surface and comprises a material to which the powder material does not adhere.
    • 提供喷嘴以在用于将粉末材料喷射到孔表面上的冷动态气体的过程中使用。 在一个实施例中,仅作为示例,喷嘴包括管和涂层。 管被构造成将粉末材料引导到孔表面并且具有内表面,轴向部分,径向部分和弯曲部。 轴向部分的内表面的至少一部分限定会聚/发散的流动路径,并且轴向部分和径向部分相对于彼此以预定角度设置,并且包括设置在其间的弯曲部。 涂层设置在管内表面的至少一部分上,并且包括粉末材料不粘附的材料。

    • A fixed broadband wireless data access service providing shared wide-band packet-switched data transport for high speed data access in areas where conventional ADSL service and fiber optic service are unavailable. The wireless data access service is a point-to-multipoint cellular-type network that connects customers to data service providers through the ATM backbone of an existing network. Customers connect to the ATM backbone and data service provider through a cellular grid in which a wireless base station in each cell communicates with the individual customer wireless equipment within its cell site coverage area. The base stations are connected to an ATM backbone switch through wireless and wireline backhaul links. The upstream and downstream bandwidths of the wireless broadband network are engineered in various symmetric and asymmetric configurations to provide a shared packet-switched connection that emulates an uninterrupted, direct wireline ADSL connection. The wireless broadband network employs a data protocol of shared access bandwidth and adaptive asymmetric data rates to support multiuser service sessions by wireless transmission. The wireless broadband network is not network protocol specific and can be applied to wireless asymmetric digital subscriber line service, wireless integrated service digital network over digital subscriber line service, wireless very high bit rate digital subscriber line service, or wireless symmetric or single-line digital subscriber line service.
    • 一种固定宽带无线数据接入服务,在常规ADSL业务和光纤业务不可用的地区提供共享的宽带分组交换数据传输,用于高速数据接入。 无线数据接入服务是一个点对多点的蜂窝式网络,通过现有网络的ATM主干将客户连接到数据服务提供商。 客户通过蜂窝网格连接到ATM主干和数据服务提供商,其中每个小区中的无线基站与其小区站点覆盖区域内的个体客户无线设备进行通信。 基站通过无线和有线回程链路连接到ATM主干交换机。 无线宽带网络的上行和下行带宽被设计成各种对称和不对称配置,以提供模拟不间断的直接有线ADSL连接的共享分组交换连接。 无线宽带网络采用共享接入带宽和自适应非对称数据速率的数据协议,通过无线传输支持多用户业务会话。 无线宽带网络不是特定的网络协议,可以应用于无线非对称数字用户线路业务,数字用户线业务无线综合业务数字网络,无线非常高比特率数字用户线业务或无线对称或单线数字 用户线服务。
