    • Markers for aerial targets, also known as clay pigeons, of the type which shatter when hit by one or more pellets. The marker may comprise a ring of resilient material having a wail adapted to engage outwardly the rim of a standard clay pigeon target; may take the form of a dished disk having an upwardly curving central portion which fits into the underside of a clay pigeon target and an upwardly directed wail which has an internal diameter substantially the same as the outer rim of such a target, or it may take the form of a simple annulus having inner and outer upwardly directed wails which engage the lower rim of the target and are maintained in position by frictional contact between the wails and the rim. The wall of the marker engaging outwardly the rim of a clay pigeon target may carry a series of incisions or be formed as a castellated ring. In an other embodiments, the marker may comprise a central disc-shaped core carrying a plurality of legs directed outwardly with feet adapted to engage the rim of a standard clay pigeon target by frictional and/or adhesive forces, or it may be a cap. The markers are constructed from a material with sufficient resilience to engage the rim of the target and which does not shatter such as metal, a synthetic resin polymer or a composition based thereon. A preferred synthetic resin is high impact polystyrene which may be painted or pigmented with a distinctive color.
    • 用于空中目标的标记,也称为粘土鸽,当被一个或多个粒子撞击时,其破碎的类型。 标记可以包括弹性材料环,其具有适于与标准粘土鸽目标的边缘向外接合的壁; 可以采取具有向上弯曲的中心部分的碟形的形状,该中心部分适合于粘土鸽目标的下侧和具有与该目标的外缘基本上相同的内径的向上导向的小窝,或者可以采取 具有内部和外部向上指向的凹部的简单环形的形式,其接合目标的下边缘并且通过所述凹口和所述边缘之间的摩擦接触而保持在适当位置。 标记在粘土鸽目标边缘外侧的墙壁可以携带一系列切口或形成为一个城堡环。 在其他实施例中,标记可以包括中心盘状芯,该中心盘状芯承载多个脚,其指向外侧,脚适于通过摩擦和/或粘合力与标准粘土鸽目标的边缘接合,或者它可以是帽。 标记由具有足够弹性的材料构成,以接合靶的边缘并且不会破碎的材料,例如金属,合成树脂聚合物或基于其的组合物。 优选的合成树脂是高抗冲聚苯乙烯,其可以用鲜明的颜色涂漆或着色。

    • A multiple electrical receptacle unit adapted to be attached to a wall-mounted receptacle has a housing including a plurality of prong-receiving apertures penetrating the housing and a perimetric edge defining a wall-facing opening; a coupling means including a back plate which is integral with a plurality of pods as well as a plurality of spacers situated between the back plate and the pods, and a plurality of plugs having prongs projecting through the back plate for engagement in a wall receptacle. The coupling means is received within the perimetric edge of the housing to define a space between the plate and the housing, and the pods are within the housing adjacent to the apertures. Each pod encases a plurality of contact strips, and each strip is aligned with at least two of the apertures of the housing and is electrically connected to the prong of the plug.
    • 适于附接到壁挂式插座的多个电插座单元具有壳体,该壳体包括穿过壳体的多个插脚接收孔和限定壁面开口的周边边缘; 耦合装置包括与多个容器一体的背板以及位于背板和容器之间的多个间隔件,以及多个插头,其具有通过后板突出以插入壁插座中的插脚。 联接装置被容纳在壳体的周边边缘内以限定板和壳体之间的空间,并且荚在邻近孔的壳体内。 每个荚包装多个接触条,并且每个条带与壳体的至少两个孔对准并且电连接到插头的插脚。
