    摘要： A process for making metal joining paste, particularly suitable for precision soldering and brazing, which comprises preparing a paste vehicle by mixing together, at an elevated temperature, paste ingredients including solvent, flux and specialized additives, cooling said vehicle, and blending metal powder therewith. Blending preferably is subsequent to cooling, but can be simultaneous with cooling, though without significant exposure of the metal to the vehicle at elevated temperature. Cooling of the vehicle takes place under shock cooling conditions, such as to obtain a fine particle size suspension, and is to a final temperature inhibitive of significant reaction of metal powder with vehicle acidic constituents. The present invention provides increased viscosity control and suspension stability necessary for fine bore automatic dispensing of the paste.

    摘要： A bicycle hand placement surface element for bicycles with hand brakes mounted on drop style handlebars that creates a new ergonomic hand position while riding the bicycle that reduces stress in the hand, palm, web and wrist while absorbing significant road shock and vibration. This element may be self forming to each riders hand and is significantly larger than the top of a hand brake to better distribute the rider's weight uniformly across the riders palm to reduce high pressure points. This element can be added to an existing hand brake, made as an integral part of the hand brake or mounted separately to the handlebars.

    摘要： A coffee brewing unit is disclosed which enables a brew cycle to be initiated automatically upon insertion of a coffee receiving vessel into its coffee receiving position, but which prevents a brew cycle from proceeding if a number of required operating conditions are not implemented. If all operating conditions again become implemented after a brew cycle, once underway, is interrupted, the brew cycle continues on to completion. Visual signals indicate that a brew cycle is in progress and also when sufficient mineral deposits are present that cleaning of the unit is recommended. An insulated carafe is used as the vessel to receive brewed coffee thereby eliminating the need for a warmer plate. The unit may be mounted under a cabinet to thereby maximize usable countertop space and a coffee basket for the unit utilizes a dispensing valve which is opened by the carafe when inserted into position but which closes when the carafe is withdrawn. A thermostat which is used in association with the water generator for the unit has a manual reset switch which is actuated by a self contained water reservoir when moved into its operating position.

    摘要： For a coffee brewing machine, an indicating system which operates to notify the user when it is time to clean the water supply conduit of accumulated mineral deposits. When a self contained removable reservoir is inserted into its operative position connecting to the water supply conduit, it closes the contacts of a temperature sensitive switch. During normal operation, the switch opens when water is depleted from the reservoir and the brewing cycle is completed. However, if the switch opens while water remains in the supply conduit upstream of the heater mechanism, this is a sure indication that there is a substantial accumulation of mineral deposits in the supply conduit. Thus, a sensing mechanism is employed to detect the presence of water in the supply conduit after the temperature sensitive switch opens, and a lamp is energized to indicate the condition. In one embodiment, the sensing operation is performed by an electromechanical device, and in another embodiment by logic circuitry.

    摘要： A LAN has a wireless portion which includes access points and wireless communications devices and a wired portion which includes such things as routers, servers, and a PBX. The LAN operates in a radio frequency band where certain channels (DFS channels) are shared with a signal that is of higher priority than the communications signals transmitted and received by the access point and the wireless communications devices. If a higher priority signal is sensed on a particular channel of the wireless medium by a master device, it is necessary for all of the slave devices communicating on this channel to stop transmitting on that channel within a short period of time. The wireless communications devices are mobile and can be easily transported around in space or roam during a communications session. While roaming during a communications session, it is likely that the communications device will move out of range of an access point with which it is currently associated and possibly cause the session to end prematurely, and so it is important that a handoff procedure operates so that a communications session is continuous as the communications device roams from access point to access point. By setting and maintaining a timer dedicated to each available DFS channel, it is possible to ensure that the communications sessions is not interrupted during the roaming process in an environment were certain channels are shared with a higher priority signal.

    摘要翻译： LAN具有包括接入点和无线通信设备的无线部分以及包括诸如路由器，服务器和集团电话之类的有线部分。 LAN工作在无线电频段，其中某些信道（DFS信道）与比由接入点和无线通信设备发送和接收的通信信号优先的信号共享。 如果由主设备在无线介质的特定信道上感测到较高优​​先级信号，则在该信道上通信的所有从设备在短时间段内停止在该信道上的传输是必要的。 无线通信设备是移动的，并且可以在通信会话期间容易地在空间中漫游或漫游。 在通信会话期间漫游时，通信设备很可能移动超出其当前关联的接入点的范围，并且可能导致会话过早结束，因此重要的是切换过程操作使得 当通信设备从接入点漫游到接入点时，通信会话是连续的。 通过设置和维护专用于每个可用的DFS信道的定时器，可以确保通信会话在环境中的漫游过程期间不被中断，某些信道与较高优先级信号共享。
