    • A vacuum-sealable hatch that is vacuum sealed to a surface of a passthrough light sterilization device, and related methods of use, consists of a hatch body having at least a portion adapted to fit within an opening of the treatment chamber and a flexible piece attached to the hatch body. The flexible piece extends peripherally from the hatch body and includes a seating portion which is adapted to be vacuum sealed to a seating region of an interior surface of the treatment chamber. The hatch body and the flexible piece seal the treatment chamber from the outside environment, thereby preventing the free flow of microorganisms to and from the treatment chamber and the outside environment. In some variations, at least the seating portion of the flexible piece is transmissive to the light treatment such that surfaces underneath the seating region are treated by the light treatment.

    • A reflow solder head has its heater bar (30) mounted so as to cause the heater bar to contact a tilted reflow surface (50) and align itself with the tilted surface without tip skid. The heater bar is mounted to its movable drive ram (40) by two independent pivots (36,42), both nominally positioned on a line normal to and in the center of the heater bar itself. The first pivot (36) closer to the heater bar allows the heater bar to rotate about its first point of contact (54) with the tilted reflow surface. The second pivot (42) allows lateral movement of the first pivot (36) without tip skid during the rotation of the heater bar about its first point of contact. This double pivot mechanism eliminates the tendency of the heater bar to skid along the reflow surface.
    • 回流焊头具有其加热棒(30),其安装成使得加热棒接触倾斜的回流表面(50),并使其自身与倾斜的表面对准,而没有尖端滑动。 加热器杆通过两个独立的枢轴(36,42)安装到其可移动的驱动柱塞(40)上,两个标称位于加热棒本身的法线上和中心的直线上。 更靠近加热棒的第一枢轴(36)允许加热棒围绕其第一接触点(54)以倾斜的回流表面旋转。 第二枢轴(42)允许第一枢轴(36)的横向移动,而不会在加热器棒绕其第一接触点旋转期间引起滑动。 这种双重枢转机构消除了加热棒沿回流表面滑动的趋势。

    • Two parallel elongated closely spaced electrodes for welding electronic circuit components are mounted for limited rotation about an axis extending generally longitudinally of the electrodes to allow the electrode pair to be oriented with respect to a workpiece without angularly moving the workpiece. The electrodes are mounted in a pair of mutually aligned and mutually insulated bobbins against which are firmly pressed a pair of contacts for conducting weld current between the electrodes. The bobbins and the electrodes mounted therein are free to rotate relative to the fixed contacts, but the latter are firmly pressed against the bobbins to provide increased contact pressure and decreased electrical resistance between the contacts and bobbins and to provide a relatively large surface area for such contact.
    • 安装用于焊接电子电路部件的两个平行细长的紧密间隔的电极,用于围绕电极大致纵向延伸的轴线进行有限旋转,以允许电极对相对于工件定向而不使工件成角度地移动。 电极安装在一对相互对准且相互绝缘的线轴中,牢固地按压一对触点,以在电极之间传导焊接电流。 安装在其中的线轴和电极相对于固定触点自由旋转,但是后者被牢固地压靠在线轴上,以提供增加的接触压力和降低的触点和线轴之间的电阻,并为此提供相对较大的表面积 联系。
