Abstract: A composite tube for a gun barrel consists of: an inner tubular metal liner defining a longitudinal bore axis; a resin matrix material surrounding the liner, the resin matrix material containing a plurality of elongate carbon fibers, the carbon fibers being aligned parallel with the longitudinal bore axis of the liner and under compression along the longitudinal bore axis; a muzzle piece attached to the muzzle end of the barrel; and a breech piece attached to the breech end of the barrel, so that any vibrations transmitted along the longitudinal bore axis of the liner are absorbed by the resin matrix material and so that any vibrations reaching the muzzle piece and breech piece are reflected back into the resin matrix material and thus absorbed. A method of manufacturing the composite tube for a gun barrel consists of the steps of: a) grinding the metal liner down from its original thickness to a greatly reduced thickness; b) applying the resin matrix material in layers about the metal liner by wrapping a carbon fiber mat with embedded resin about the metal liner under extreme pressure, until a suitable thickness of resin matrix material has been applied to the metal liner; c) compressing the wrapped resin matrix material; d) heating the wrapped resin matrix material and enclosed metal liner while maintaining compression on the resin matrix material to cure the resin matrix material; e) lathing and sanding the cured resin matrix material to the proper diameter for a gun barrel; and f) attaching the muzzle piece and breech piece to the gun barrel with the adhesive material.

Abstract: A method and apparatus for accessing customer telemetering equipment while on a voice connection between an agent of a customer server and the customer. A voice connection is initially established between a customer and an agent of a server such as a utility. The original connection may be established when a customer complains, or in response to receipt of a complaint report at an earlier time. If, during the discussion between the customer and an agent of the server, the agent believes that accessing the customer's telemetering equipment might help to uncover the problem, the agent signals a customer Telemetering Interface Gateway to allow the agent to access the appropriate telemetering equipment. After the agent has obtained information from this equipment, the agent sends another signal to the Gateway and the voice connection to the customer is re-established. Advantageously, problems can be discussed and solved while the customer is still connected to the agent, thus avoiding repeated telephone calls.

Abstract translation: 一种在客户服务器的代理和客户之间的语音连接上访问客户遥测设备的方法和装置。 最初在客户和诸如公用事业的服务器的代理之间建立语音连接。 原始连接可以在客户投诉时或在早些时候收到投诉报告的响应时建立。 如果在客户和服务器的代理商之间的讨论中，代理人认为访问客户的遥测设备可能有助于发现问题，代理人向客户发出遥测接口网关，以允许代理人访问适当的遥测设备。 代理商从该设备获取信息后，代理向Gateway发送另一个信号，并重新建立与客户的语音连接。 有利的是，当客户仍然连接到代理时，可以讨论和解决问题，从而避免重复的电话呼叫。

Abstract: A personnel carrying vehicle comprising a self propelled, steerable body, a telescoping mast attached to and extending upwardly from said body, and a personnel compartment attached to the mast and provided with a rail member that extends from the mast and around the sides. A pair of gate members, which are pivotally attached to the rail member and to the floor of the compartment, are movable from a closed position to an open position wherein said gate members extend into the compartment. The mast extends upwardly and forwardly of the body at an angle of approximately five degrees to the top of the rail; this provides the operator with unobstructed access to anything above the top edge of the rail, and the forward tilt of the mast enlarges the upper portion of the compartment, near the waist of the operator, thus accommodating the operator comfortably without increasing the length of the vehicle; it also causes the center of gravity of the vehicle to move forward, toward the center of the vehicle, as the compartment is raised. The vehicle is driven by electric motors which are located under the operator compartment and attached to the drive wheels through gear trains to permit the floor of the compartment to be positioned as close to the ground level as possible. Control handles are mounted within the personnel compartment, with one handle controlling steering and the other handle controlling traction. Sensors ensure the operator's hands are on both control handles and both feet are properly positioned on the floor before the vehicle can be moved or the platform raised; this ensures a four point stance, providing for operator stability and that the operator's hands and feet are within the operator's compartment anytime the vehicle is being moved or during lifting or lowering operations. Gate interlock switches are provided to restrict or prevent travel of the vehicle under certain conditions. A load deck is provided on the body of the vehicle on the opposite side of the mast from the personnel compartment. Also, a load tray may be mounted to the telescoping mast to move vertically with the compartment. Rail guides may be mounted to the outside of the vehicle to facilitate entry into and operations within narrow aisles.

Abstract: The system of the invention consists of a central office service unit (COSU) connected to a plurality of switching systems via dedicated telemetry trunks or a common channel signaling network such as the CCS7 network. The switching systems are connected to a plurality of inbound-only TIUs located on the customer premise that are in turn connected to customer devices such as utility meters, appliances, security systems or the like. The TIUs are inbound-only that can originate calls but cannot answer calls initiated by the controlling entity. A controlling entity, such as a utility, is connected to one of the switching systems over a customer line such that the controlling entity can be connected to any TIU hosted by the switching systems. The controlling entity requests that an alerting tone be sent by the COSU to a desired TIU. The COSU, as is known in the art, delivers an alert tone through a suppressed ringing connection to the TIU that does not audibly ring the customer's telephone. The TIU does not "answer" this tone by going off hook such that no connection is established and the telemetry call is taken down. While the TIU does not answer the alert tone, the tone alerts the TIU to perform one or more functions such as retrieve data from a utility meter, check the status of an appliance or the like. As an alternative to the alert tone, a digital signal can be transmitted to alert the TIU. After performing the desired function, the TIU is programmed to call the controlling entity and a connection is established between the TIU and the controlling entity. The TIU can then transmit the results of the function to the controlling entity and the controlling entity can download further instructions, programs or the like to the TIU.

Abstract translation: 本发明的系统包括通过专用遥测中继线或诸如CCS7网络的公共信道信令网络连接到多个交换系统的中心局服务单元（COSU）。 交换系统连接到位于客户端的多个仅入站的TIU，其又连接到诸如公用事业计量表，电器，安全系统等的客户设备。 TIU是入站的，可以发起呼叫，但不能应答控制实体发起的呼叫。 诸如公用事业的控制实体通过客户线连接到交换系统中的一个，使得控制实体可以连接到由交换系统托管的任何TIU。 控制实体请求由COSU发送警报音到所需的TIU。 如现有技术中已知的COSU通过抑制振铃连接到TIU而发出警报音，TIU听不见客户的电话。 TIU不会通过脱钩来“回答”这种音调，使得不建立连接并且遥测呼叫被关闭。 当TIU不响应提示音时，音调提醒TIU执行一个或多个功能，例如从公用仪表检索数据，检查设备的状态等。 作为警报音的替代，可以发送数字信号以提醒TIU。 在执行所需功能之后，TIU被编程为呼叫控制实体，并且在TIU和控制实体之间建立连接。 然后，TIU可以将该功能的结果发送给控制实体，并且控制实体可以向TIU下载进一步的指令，程序等。

Abstract: The invention uses a connection having a predetermined priority, switched through the existing call processing switch fabric, to connect between customer premise equipment (CPE). The connection is implemented such that the connection is disconnected if an incoming call to one of the CPEs or an outgoing request for service from one of the CPEs is made that has a priority higher than the predetermined priority. If the connection is disconnected due to a request for higher priority service, the system of the invention can automatically reestablish the connection after the higher priority service call has ended.
