    • A grill that includes a base and, residing thereupon, a cooking surface in the form of a grate for supporting food to be cooked by the grill. A first removable drawer is positionable beneath the grate having at least one burner. A source of combustible fuel, such as a pressurized gas, is contained within a tank located within the base of the grill. A fuel line emanating from the pressurized tank terminates at a control valve having a first gas transmitting position facilitating the combustible fuel fed to the at least one burner and a second gas blocking position preventing the combustible fuel to be fed to the at least one burner. The control valve is capable of assuming the first gas transmitting position only if the first removable drawer has been fully positioned beneath the cooking surface. When an alternative drawer, such as one containing charcoal is employed, fuel from the pressurized tank is blocked from emanating from the tank.
    • 一种烤架,其包括基部,并且在其上驻留有格栅形式的烹饪表面,用于支撑由烤架烹饪的食物。 第一可移除抽屉可定位在具有至少一个燃烧器的炉排下方。 诸如加压气体的可燃燃料源被容纳在位于格栅基座内的罐内。 从加压罐排出的燃料管路终止于控制阀,该控制阀具有促进供给至少一个燃烧器的可燃燃料的第一气体传输位置和防止可燃燃料被供给到至少一个燃烧器的第二气体阻塞位置。 只有当第一可移除抽屉已经完全定位在烹饪表面下方时,控制阀才能够承担第一气体传输位置。 当使用替代的抽屉(例如含有木炭的抽屉)时,来自加压罐的燃料被阻止从罐中排出。

    • A mixing head for a reaction injection molding machine includes a body including a mixing chamber formed with an injection bore. In addition to a charging assembly for introducing at least two reactive components into the mixing chamber, there is provided a feed assembly having at least two feeds for supply of different additional components to the mixing chamber. A moveable adapter selectively and detachably couples the feeds of the feed assembly to the injection bore for selective introduction of the additional components. The adapter is constructed for rotation in relation to the mixing chamber so that an exit port of each feed is connectable with the injection bore through rotation of the adapter.

    • Input RF signals to a transponder, such as a communications satellite, are down converted to a lower intermediate frequency (IF) that is common for each different channel. The channel signals are all processed at the common IF, and then up converted to different respective transmission frequencies. This allows for a down conversion/signal processing/up conversion unit design that is the same for each channel (except for frequency and gain values), and facilitates the use of inexpensive available standard components as well as low bandwidth channel filters. An improved phase noise cancellation phase lock loop (PLL) is preferably used to generate tuning signals used in the up and down conversion processes. The PLL includes two loop mixers, with the down and up conversion mixing signals taken respectively from the inputs to the first and second loop mixers. The first and second loop mixers receive mixing signals at frequencies (T-R) and (T-IF-N.multidot.CLK) respectively, where T is the channel's transmission frequency, R is its reception frequency, N is the PLL's .div.N factor, and CLK is a clock frequency; the PLL's voltage controlled oscillator provides the down conversion tuning signal and the input to the first loop mixer at a frequency (R-IF), while a (T-IF) tuning signal for the up converter is taken from a filtered output of the first loop mixer.
    • 向诸如通信卫星的应答器输入RF信号被下变频到每个不同信道共同的较低中频(IF)。 通道信号全部在公共IF处理,然后上变频到不同的各自的传输频率。 这允许对于每个通道(频率和增益值除外)相同的下变频/信号处理/上变频单元设计,并且便于使用便宜的可用标准组件以及低带宽通道滤波器。 改进的相位噪声消除锁相环(PLL)优选地用于产生在上下转换过程中使用的调谐信号。 PLL包括两个环路混频器,其中分别从输入到第一和第二回路混频器的下变频和上变频混频信号。 第一和第二回路混频器分别以频率(TR)和(T-IF-NxCLK)接收混频信号,其中T是信道的传输频率,R是其接收频率,N是PLL的DIVIDED N因子,CLK是 时钟频率; PLL的压控振荡器以频率(R-IF)提供下变频调谐信号和第一回路混频器的输入,而用于上转换器的(T-IF)调谐信号从第一 回路混合器。
