Abstract: Immersion-type vacuum countergravity casting apparatus having a vacuum chamber including spring means for pressing the mold portions sealingly together and/or resisting destructive inward flexure of the mold. A split vacuum chamber, including a floating lower skirt portion, avoids the creation of stress concentration sites between the chamber and the mold.

Abstract: A face guard for a sport helmet, such as a rigid, protective baseball batting helmet or football helmet, is provided with one or more resilient couplings that permit the face guard grid to be attached to the helmet at ear hole openings in the side flaps of the helmet. The resilient couplings have one or more radial, annular channels defined therein. At least one of these channels is of a size to fit snugly within the confines of a side flap ear opening on the helmet. The structure of the resilient coupling thereby defines a resiliently compressible helmet attachment flange for insertion through an ear opening in one of the ear flaps of the helmet and a resiliently compressible mounting clip attachment flange for insertion into the helmet attachment opening of the mounting clip. The face guard may thereby be releaseably coupled to and detached from the sport helmet without any modification to the helmet whatsoever and in a manner that protects the helmet from damage.
Abstract translation: 用于运动头盔的防护面具,例如刚性的保护性棒球击球头盔或足球头盔,设置有一个或多个弹性联轴器,其允许防护网格在侧翼的耳部孔的耳孔处附接到头盔 头盔。 弹性联轴器具有限定在其中的一个或多个径向环形通道。 这些通道中的至少一个具有适合紧贴在头盔上的侧翼耳朵开口的范围内的尺寸。 弹性联接器的结构由此限定弹性可压缩的头盔附件凸缘,用于插入穿过头盔的一个耳片中的耳朵开口,以及可弹性压缩的安装夹附件凸缘,用于插入到安装夹的头盔附件开口中。 因此,防护罩可以可释放地联接到运动头盔上并从运动头盔拆卸,而无需对头盔进行任何修改,并且以保护头盔免受损坏的方式。

Abstract: A helmet apparatus includes a head-covering assembly which includes a top portion and a side portion extending downward from the top portion. A guard support is connected to the side portion of the head-covering assembly, and a guard assembly is connected to the guard support. The helmet apparatus of the invention can be used as a batter's helmet to protect a batter in a baseball or softball game. The guard assembly can be installed when a player is batting, and the guard assembly can be easily removed when the player is no longer batting. The guard assembly includes a lower guard portion for covering a wearer's chin and an upper guard portion for covering a wearer's cheek. With a first embodiment of the invention, the guard support includes a guard support bracket, and the guard assembly includes bracket-connection portions for connecting to the guard support bracket. The guard support bracket includes a reception panel which includes a plurality of reception apertures. The bracket-connection portions of the guard assembly include hook members which are received in the reception apertures. The reception apertures are in a form of slots oriented longitudinally along the reception panel. With a second embodiment of the invention, the guard support includes grooves located in the side portion of the head-covering assembly, and the guard assembly includes tongue portions for connection with the grooves. The grooves extend horizontally along the side portion of the head-covering assembly.
Abstract translation: 头盔装置包括头部覆盖组件,其包括顶部和从顶部向下延伸的侧部。 保护支撑件连接到头部覆盖组件的侧部,并且保护组件连接到防护支架。 本发明的头盔装置可以用作面糊的头盔,以在棒球或垒球比赛中保护面糊。 当玩家殴打时,可以安装警卫组件,并且当玩家不再击球时可以方便地拆下警卫组件。 护罩组件包括用于覆盖佩戴者下巴的下护罩部分和用于覆盖佩戴者的脸颊的上保护部分。 在本发明的第一实施例中,防护支架包括防护支架,并且防护罩组件包括用于连接到防护支架的支架连接部分。 保护支撑托架包括包括多个接收孔的接收面板。 保护组件的支架连接部分包括接纳在接收孔中的钩构件。 接收孔是沿着接收面板纵向定向的槽的形式。 在本发明的第二实施例中,防护支架包括位于头部覆盖组件的侧部中的槽,并且保护组件包括用于与槽连接的舌部。 凹槽沿着头部覆盖组件的侧部水平延伸。
