摘要： A communication system operates compatibly with a public or private switching network using a Q.931 protocol for basic rate ISDN communications. Communications between a control unit and station terminals of the system use a local protocol which is a modification of the Q.931 protocol. This local protocol includes one segment including the mandatory elements of the Q.931 protocol and a second segment derived by converting the optional elements of the Q.931 protocol into a local codeset which controls the user interface circuits at each station terminal. The local protocol enables call control between the control unit and each station terminal to be managed on a bearer channel basis while call control between the system and the network is managed on a call appearance basis using the standard Q.931 protocol. The local protocol provides for communicating line selection and feature activation commands from the terminal to the control unit, using simple button commands.
摘要翻译： 通信系统与公共或专用交换网络兼容，使用Q.931协议进行基本速率ISDN通信。 系统的控制单元和站终端之间的通信使用本地协议，这是Q.931协议的修改。 该本地协议包括包括Q.931协议的强制元素的一个段，以及通过将Q.931协议的可选元素转换成控制每个站终端的用户接口电路的本地代码集导出的第二段。 本地协议使得控制单元和每个站终端之间的呼叫控制能够在承载信道的基础上进行管理，同时使用标准Q.931协议在呼叫状态下管理系统与网络之间的呼叫控制。 本地协议提供从终端到控制单元的线路选择和功能激活命令，使用简单的按钮命令。

摘要： A glide, preferably self retaining, for the lower end of each rear leg of a walker. The device substantially reduces forward drag or resistance to walker sliding movement over a support substrate such as carpet, hard floors, concrete, ground and like, while simultaneously increasing resistance to side ways or lateral slippage. The device includes a stationary or fixed member which engages with and receives support from each walker leg lower end and includes a support shaft orientated at an acute angle of preferably about fifteen degrees (15.degree.) to the central axis of the leg. A ground engaging member is held on the support shaft for rotation only and has a lower exterior contoured ground engaging surface which, in combination with the acute angle, makes contact with the support substrate laterally from the central axis of the leg.

摘要： A self-retaining glide for the lower end of each leg of a walker. Preferably installed onto each rear leg of the walker, the device decreases forward drag while substantially increasing resistance to sideways or lateral movement by providing a plurality of downwardly facing or extending parallel ground, floor and carpet engaging fins. These fins are a molded part of an elongated main member which also includes one and preferably two spaced apart tubular supports for retaining the device in proper position on the leg lower end. In the preferred embodiment, the combination of snugly fitting tubular supports on the leg and resilient flexing of a semi-rigid central portion of the main member from a flat to a U-shape securely maintains the fins in a fore/aft orientation with respect to the walker after proper installation.

摘要： An adapter consists of a more or less cylindrical body having a rear outer portion and a front inner portion, projections (or other suitable coupling means) on the rear outer portion for effecting the coupling to an automatic adjusting device, and at least three different recessed configurations located at different depths within the body's front inner portion for mating respectively to at least the three most common types of residential thermostat knobs. The most recessed configuration receives the smallest such knob, which is of the "lever" type. The middle configuration is a circular ring of inwardly projecting teeth for engaging the intermediate size "serrated" type of knob. The least recessed configuration is of an internal bevelled shape for receiving the largest such knob, namely the "bevel" knob. These various recessed configurations are so located and dimensioned with respect to the body of the adaptor to allow each type of knob to reach and mate with its corresponding recessed configuration.

摘要： A cover assembly for an attic fan or the like permanently mounted in a wall or ceiling is provided which permits quick, easy covering of the fan opening when the fan is not in use during wintertime. The cover assembly is provided with heat insulation and a peripheral seal so that heat loss through the fan opening is minimized. In preferred forms, the cover assembly includes an insulated shell having a circumscribing lip which is adapted for face-to-face mounting adjacent the rim or flange of the fan assembly; a plurality of spring clips are employed for interconnecting the shell lip and fan rim for assuring a tight covering fit over the fan opening.

摘要： A toy spa (10) is provided with water (56) and an aerating manifold (18) in the base (16) of the spa. Pressurized air is provided to the manifold via a bellows pump and passes through the water from openings (20) in the manifold. To reduce the surge effect of the bellows pump an expandable reservoir means (40) is provided between the bellows pump and the aerating manifold (18). Air is pumped from the bellows pump directly into the expandable reservoir through a one way valve (32) moved by the pressurized air. Air exits from the expanded reservoir via a restricted opening (44) which enables the pressurized air to be first stored within the expandable reservoir and to then be delivered to the manifold in a continuous, even manner.
