摘要： An electrical plug and receptacle relying on magnetic force to maintain contact are disclosed. The plug and receptacle can be used as part of a power adapter for connecting an electronic device, such as a laptop computer, to a power supply. The plug includes electrical contacts, which are preferably biased toward corresponding contacts on the receptacle. The plug and receptacle each have a magnetic element. The magnetic element on one or both of the plug and receptacle can be a magnet, which is preferably a permanent rare earth magnet although electromagnets may also be used. The magnetic element on the plug or receptacle that does not include a magnet is composed of ferromagnetic material. When the plug and receptacle are brought into proximity, the magnetic attraction between the magnet and its complement, whether another magnet or a ferromagnetic material, maintains the contacts in an electrically conductive relationship.

摘要： The invention generally pertains to a portable computer having a base and a lid. More particularly, the invention pertains to an improved locking system for securing the base relative to the lid. One aspect of the invention relates to a latch that is placed in a recess when the lid is opened so as to eliminate unsightly and harmful protrusions. Another aspect of the invention relates to a latch that is automatically extracted from the recess when the lid is closed so as to secure the lid to the base. For example, a magnetic actuator may be used to automatically extract the latch when the lid is closed. Yet another aspect of the invention relates to a button for releasing the secured latch so as to allow the lid to be opened.

摘要： A slicer for tube gels or strips from a slab gel which includes a cutting plate having a plurality of blades in spaced parallel relation extending between the sides of the cutting plate. The spaces between the blades are configured with a cutting edge on one side thereof. The plate is mounted in a holder which is driven by a rotating cam mounted on a drive motor shaft which contacts a cam follower on an arm attached to the cutting plate holder. A pedestal is provided for supporting the gel slab strip or tube gel. The gel is retained laterally on the pedestal by means of retaining vanes on each side of the pedestal. The retaining vanes are urged by springs to extend above the surface of the pedestal. The cutting plate holder is rotatably attached to a framework for mounting the drive motor and the support pedestal so that it may be alternately positioned overlying the pedestal and in a remote position. A weight is attached to the cutting plate holder which is radially adjustable about the axis of rotation of the cutting plate holder. Adjustment of the radius of the weight from the axis of rotation allows adjustment of the force applied to the cutting plate holder for urging the cutting plate toward the pedestal. A gel to be sliced is placed on the pedestal, the cutting plate is positioned to overlie the gel with the cutting edges of the plurality of blades in contact with the gel, and the motor is actuated causing reciprocating motion of the cutting blades. The cutting blades advance through the gel depressing the springs supporting the retaining vanes, thereby pushing the retaining vanes ahead of the cutting blades until the cutting blades pass through the gel and contact the surface of the pedestal.
摘要翻译：一种用于来自板坯凝胶的管凝胶或条带的切片机，其包括切割板，该切割板具有在切割板的侧面之间延伸的间隔开的平行关系的多个叶片。叶片之间的空间在其一侧配置有切削刃。板被安装在由安装在驱动马达轴上的旋转凸轮驱动的保持器中，该驱动马达轴接触附接到切割板保持器的臂上的凸轮从动件。提供了用于支撑凝胶板条或管凝胶的基座。凝胶通过在基座的每一侧上的保持叶片横向地保持在基座上。保持叶片由弹簧推动以延伸到基座的表面之上。切割板保持器可旋转地附接到用于安装驱动马达和支撑基座的框架，使得其可以交替地定位在基座上并位于远程位置。重量附接到切割板保持器，其可围绕切割板保持器的旋转轴线径向调节。从旋转轴线调整重量的半径允许调节施加到切割板保持器的力以将切割板推向基座。要切片的凝胶放置在基座上，切割板被定位成与多个叶片的切割边缘与凝胶接触而覆盖在凝胶上，并且马达被致动，引起切割刀片的往复运动。切割刀片通过凝胶按压支撑保持叶片的弹簧，从而将保持叶片推向切割刀片前方，直到切割刀片通过凝胶并接触基座的表面。
