    • An alignment device for maintaining the relative alignment between a gate valve assembly and a valve bonnet positioned over the gate valve assembly wherein the valve bonnet has an interior surface. The alignment device includes a pair of substantially identical components wherein the components are securely connectable to each other when the alignment device is attached to the gate valve assembly. Each one of the components includes a body that has a peripheral portion. The peripheral portion is adjacent to the interior surface of the valve bonnet when the valve bonnet is positioned over the gate valve assembly. The body also has a transverse edge wherein the transverse edge contains an opening that receives a part of the gate valve assembly when the components are connected together.

    • A safety device to be worn by a diver includes means for monitoring the breathing of the diver and causing release and inflation of a surface marker buoy attached thereto by a line if it detects he has stopped breathing. The monitoring means may also be operable to cause release of a cover of the device allowing the surface marker buoy to rise or the cover may be a simple friction fit pushed aside by the inflating marker buoy. The monitoring means includes a transducer monitoring the pressure of gas breathed, or the flow of gas inhaled or exhaled, by a diver. Various forms of electrical and electro-mechanical logic circuits are described, each of which provides for the comparison over pre-set or pre-settable time intervals of measurements made of gas pressure or flow rate values with pre-set values or with earlier recorded values. The device may be incorporated in the divers breathing equipment or be separate from the equipment but linked to the equipment by a flexible connection. The line has a breaking strain enabling a diver to be pulled to the surface by any associate or assistant on the surface. A radio beacon may be activated and a marker dye released when the buoy is deployed. Switches are provided disabling operation of the device at less than a predetermined depth and allowing the diver to prevent and/or trigger operation of the device.
    • 由潜水员佩戴的安全装置包括用于监测潜水员呼吸的装置,并且如果检测到他已经停止呼吸,则使其附接到其上的表面标记浮标的释放和充气。 监视装置还可以可操作地引起装置的盖的释放,允许表面标记浮标升高,或者盖可以是由充气标记浮标推开的简单的摩擦配合。 监测装置包括监测潜水员呼吸的气体压力或吸入或呼出的气体的流量的换能器。 描述了各种形式的电气和机电逻辑电路,其中每个电路和机电逻辑电路提供了对具有预设值或具有较早记录值的气体压力或流量值的测量值的预设或可预设时间间隔进行比较 。 该装置可以并入潜水员呼吸设备中,或者与设备分离,但通过柔性连接与设备相连。 该线具有使潜水员能够被表面上的任何助手或助手拉到表面的断裂应变。 可以激活无线电信标,并且当浮标被部署时,标记染料被释放。 开关被提供在小于预定深度的设备的禁用操作,并允许潜水员防止和/或触发设备的操作。

    • A rotary cutting knife for paper cutting apparatus or the like includes a circular periphery carrier with a planar front face and a peripheral wall. Cylindrical bores in the peripheral wall receive cylindrical blade inserts. Each blade insert includes at its outer end an inclined planar blade face which intersects the cylindrical insert wall to form a cutting edge of elliptical contour. The insert receiving bores in the carrier are so oriented that inserts can be and are mounted therein with their blade faces all lying in a cutting plane parallel to the planar front face of the carrier and perpendicular to the axis of carrier rotation. Additionally, the bore orientation is such that the outer ends of the inserts lag their inner ends in the direction of carrier rotation. The assembly provides improvements in strength, blade wear life and precision of cut.
    • 用于切纸设备的旋转切割刀等包括具有平面前表面和周边壁的圆形周边托架。 外围壁上的圆柱孔容纳圆柱形刀片插入物。 每个刀片插入件在其外端包括倾斜的平面刀片面,其与圆柱形插入件壁相交以形成椭圆轮廓的切割边缘。 载体中的插入物接收孔被定向成使得插入件可以并且被安装在其中,其刀片面全部位于平行于载体的平面前表面并且垂直于载体旋转轴线的切割平面中。 此外,孔取向使得插入件的外端在载体旋转方向上滞留其内端。 该组件提供强度,刀片磨损寿命和切割精度的改进。

    • An elongate bunker spike that secures a flexible golf bunker liner to the earth strata when the bunker spike is driven through the bunker liner into the earth strata. The bunker spike has a point member adjacent to the axial forward spike end, a ribbed member adjacent to the axial rearward spike end and wherein the ribbed member is contiguous with the point member. A head is at the axial rearward spike end wherein the ribbed member joins the head at the underneath surface. A barb extends from the underneath surface of the head whereby the barb engages the flexible golf bunker liner when the elongate bunker spike is embedded in the earth strata.
