    • An antenna may include an enclosure formed by a front wall and a back wall opposite to the front wall, and a front face and a back face opposite to the front face. Both the front face and the back face extend between the front wall and the back wall to form a cavity within the enclosure. The enclosure further includes a slot formed in the front face to form a cavity backed slot. A radio frequency (RF) connector is mounted in the front wall. A shaped feed line is mounted within the cavity and is electrically connected to the RF connector to transmit and receive RF energy. The shaped feed line extends across the slot to couple the RF energy between the slot and the shaped feed line. The shaped feed line has a predetermined structure to substantially reduce an electric field strength to improve power handing of the antenna.

    • A fixed pitch wind turbine rotor (18) is teeter mounted (76, 78, 80) onto a low speed input shaft (44) which is connected to the input (58) of a step-up transmission (46). The output (48) of the transmission (46) is connected to a rotary pole amplitude modulated induction machine (42) which is operable as a generator at a plurality of discreet speeds of rotation and is also operable as a startup motor for the rotor. A switch (45) responsive to the rotational speed of the wind turbine rotor switches the generator from one speed of operation to the other. The rotor hub (72) and the inner body portions (71) of two blades (68, 70), which extend radially outwardly in opposite directions from the hub (72), are constructed from steel. The outer end portions (73) of the blade (68, 70) are constructed from a lighter material, such as wood, and are both thinner and narrower than the remainder of the rotor. The outer end section (73) of each blade (68, 70) includes a main body portion and a trailing edge portion (104) which is hinge-connected to the main body portion. Each blade (68, 70) includes a centrifugal force operated positioning means (98, 100) which normally holds the drag brake section (104) in a retracted position, but operates in response to a predetermined magnitude of centrifugal force to move the drag brake (104) section into its deployed position. Each blade has an airfoil cross section and each blade (68, 70) has a plus twist inner portion adjacent the hub (72) changing to first a zero twist and then a minus twist as it extends radially outwardly from the hub (72).
    • 固定间距风力涡轮机转子(18)在连接到升压变速器(46)的输入端(58)的低速输入轴(44)上安装(76,78,80)。 变速器(46)的输出(48)连接到旋转磁极调幅感应电机(42),该感应电机可以多个离散的转速作为发电机工作,并且也可用作转子的起动电动机。 响应于风力涡轮机转子的转速的开关(45)将发电机从一个操作速度切换到另一个。 两个叶片(68,70)的转子轮毂(72)和内部主体部分(71)由与轮毂(72)相反的方向径向向外延伸。 叶片(68,70)的外端部(73)由诸如木材的较轻的材料构成,并且比转子的其余部分更薄和更窄。 每个叶片(68,70)的外端部分(73)包括主体部分和与主体部分铰链连接的后缘部分(104)。 每个叶片(68,70)包括离心力操作的定位装置(98,100),其通常将牵引制动部分(104)保持在缩回位置,但是响应于预定大小的离心力而起作用以使牵引制动器 (104)部分到其部署位置。 每个叶片具有翼型横截面,并且每个叶片(68,70)具有与轮毂(72)相邻的加捻内部部分,首先从毂(72)径向向外延伸到零捻,然后改变负扭。

    • Disclosed herein is a syringe sterilization and disposal unit which utilizes a micro-processor controlled artificial intelligence for operation of the necessary functions to render a used syringe safe for disposal. The syringe sterilization unit includes an "opto-sensor" for signaling the positioning of the syringe for further clamping and processing operations. The lure of a syringe to be processed is exposed to heat from the heat heads to effect separation of the needle. The needle tip gripper jaw heads extract the syringe needle from the syringe body. The heat heads are further used to compress the lure of the syringe body to seal the syringe cavity. The extracted needle is then heated by a needle tip contactor for sterilization whereupon the needle and the sealed syringe cavity are then positioned into an appropriate bin for disposal and/or recycling.

    • An improved wastewater treatment process is provided which utilizes a rotating biological contactor (RBC) containing at least two stages as the secondary treatment phase. In such RBC, biological oxidation of carbonaceous and nitrogenous matter is accomplished simultaneously in a partially submerged aerated RBC arranged for multiple stage treatment. Wastewater being charged to the RBC is preliminarily subjected to particulate separation and admixing with biologically treated and the clarified effluent from the RBC at a rate sufficient to produce a wastewater feed to the RBC system which has approximately acceptable standards of SBOD.sub.5 and NH.sub.3 -N. The process also features a high flow rate of the diluted wastewater through the RBC.
