    • A method is provided of forming a multi-pack container assembly having at least four containers joined together by a cross or plus shaped frangible web. The method includes the steps of providing at least one male mold member and at least one female mold member, disposing the mold members so as to define at least four container cavities separated by a cross or plus shaped web cavity, injecting the cavities with a plastics material to form the multi-pack container assembly, and releasing the multi-pack container assembly from the mold members. Preferably, the method is used to form multi-peck containers, such as yogurt or pudding containers, where each individual container can be easily separated from the multi-pack container assembly.
    • 提供了一种形成具有至少四个容器的多包装容器组件的方法,所述至少四个容器通过交叉或加成形的易碎卷材连接在一起。 该方法包括以下步骤:提供至少一个阳模构件和至少一个阴模构件,设置模具构件以限定由十字形或正型网状空腔分隔开的至少四个容器空腔,用塑料 材料以形成多包装容器组件,以及将多包装容器组件从模具部件中释放出来。 优选地,该方法用于形成多啄容器,例如酸奶或布丁容器,其中每个单独的容器可以容易地与多包装容器组件分离。

    • An apparatus and method for attaching a trailer to a vehicle. An apparatus is provided having a winch attached to the trailer for pulling the trailer to the vehicle, a substantially flat strap connected to the winch at one end and having a flat attachment member with an aperture therethrough at the other end for placement over the ball portion of a hitch at the other end for connecting the trailer to the vehicle, and a multi-position arm attached to the trailer forward of the winch for lifting the receiver portion up and over the ball portion of the hitch when the strap is effectively shortened by winding it up on the winch. The arm is pivotally attached at one end by a block on the underside of the tongue of the trailer. A bearing member is disposed at the other end of the arm. The arm may be moved backward to a first-position and pinned in place so that it is tucked underneath the tongue for storage. To connect the trailer to or release it from the vehicle, the arm is locked into a second position so that it extends downward, the connector on the end of the strap is placed over the ball on the vehicle, and the winch is cranked so that the trailer is lifted up by the arm on the strap.
    • 一种用于将拖车附接到车辆的装置和方法。 提供一种装置,其具有连接到拖车上用于将拖车拉到车辆上的绞盘,在一端连接到绞盘的基本平坦的带,并且具有平坦的附接构件,在另一端具有穿过其的孔,用于放置在球部分上 在另一端用于将拖车连接到车辆上的连接装置;以及多个位置臂,其连接到绞盘前方的拖车,用于当带子被有效地缩短时,将接收器部分上下提升接合部分 卷起绞车。 臂在一端通过拖车舌头下侧的块枢轴连接。 轴承构件设置在臂的另一端。 手臂可以向后移动到第一位置并被固定在适当的位置,使得它被卷在舌头的下面用于存储。 为了将拖车连接到车辆上或将其从车辆上拆下,臂被锁定在第二位置,使其向下延伸,带的端部上的连接器被放置在车辆上的球上,并且绞盘被起动,使得 拖车由吊带上的手臂抬起。

    • A mechanism for mounting a spool on a shaft is the subject of the present invention. First and second bearing means are provided which are designed to fit over the shaft and be received within the openings of a large wooden spool. Each bearing has a frusto-conical annular surface so that it can accommodate different sized openings in the spool. A sleeve member abuts one of the bearings and is comprised of first and second sleeve components which are complementally threaded. Means is provided for rotating the two sleeve components relative to each other whereby the effective length of the sleeve may be increased or decreased. This provides means for providing a lateral force acting against one of the bearings which in turn controls the speed of rotation of the spool. When it is desired to stop rotation of the spool, the two sleeve components are turned relative to each other a sufficient distance so as to apply a lateral force against the spool a sufficient magnitude to stop all rotation.
    • 用于将线轴安装在轴上的机构是本发明的主题。 提供第一和第二轴承装置,其被设计成装配在轴上并被容纳在大型木制卷轴的开口内。 每个轴承都有一个截头圆锥形的环形表面,使其可以容纳阀芯中不同尺寸的开口。 套筒构件邻接其中一个轴承并且由互补螺纹的第一和第二套筒构件组成。 提供了用于相对于彼此旋转两个套筒部件的装置,由此套筒的有效长度可以增加或减小。 这提供了用于提供作用于轴承中的一个的横向力的装置,其进而控制滑阀的旋转速度。 当需要停止卷轴的旋转时,两个套筒部件相对于彼此转动足够的距离,以便对卷筒施加足够大的程度的横向力以停止所有旋转。
