  • Publication number: 20030231476
    Abstract: An apparatus for separating and extracting printed circuit boards in a computer system. More specifically, a basket assembly is provided through which a number of printed circuit boards may be attached to a motherboard. A card divider and extractor assembly including a card divider and card extractor is coupled to the basket assembly between each of the printed circuit boards. The card dividers provide structural and electrical isolation between the printed circuit boards. The card extractors provide a mechanism whereby printed circuit boards can be easily removed from the system while the system is operational.

  • Publication number: 20030207605
    Abstract: A self-locking mechanism usable in conjunction with a printed circuit assembly (PCA). The self-locking mechanism generally comprises a central actuator, a pair of sliding members on either side of the actuator and one rotating lock member associated with each sliding member. The actuator, sliding members and rotating members preferably are mounted to a top edge of a vertically-mounted circuit board thereby forming the printed circuit assembly. The printed circuit assembly can only be removed from its host system after the actuator is turned to an unlocked position and then the sliding members are slid toward the actuator thereby causing the rotating lock members to disengage from their locked position. Turning the actuator also causes a signal to be asserted to the host system to disable power to the PCA. Upon installing the PCA, no power is provided to the PCA until it has been fully installed and the actuator locked.

  • Patent number: 6639147
    Abstract: An EMI clip retaining system including a flexible EMI clip with a center contact portion that bows upwards and inwards from acute bends situated at the outer ends of the EMI clip and also including enlarged end portions that extend flatly inwards from the acute bends. The EMI clip is captively installable in a planar mounting surface with tapered mounting holes through which the enlarged end portions of the EMI clip are inserted, such that once the EMI clip is installed, the enlarged ends of the EMI clip reside on a bottom side of the mounting surface while the center contact portion bows upward from the opposite, top side of the mounting surface. When the center portion is compressed flat against the top side of the mounting surface, the EMI clip lies flat against both the top and bottom sides of the mounting surface.

  • Patent number: 5966289
    Abstract: A system for securing an electronic component, such as a CPU, includes a support extending substantially in a plane and a fastener coupled to the support. The support may be a heat sink secured to a component for dissipating heat generated during operation of the component. The fastener extends through extensions or fins of the heat sink, generally parallel to the plane of the heat sink and component package. A biasing spring urges the fastener toward a disengaged position. A biased retainer maintains the biasing spring and fastener within the assembly. The component is initially engaged in a receiving socket for installation. The fastener is then engaged in the mechanical support to draw the component into full engagement. A reference surface on the securement assembly contacts the mechanical support to limit engagement of the component. The fastener may include a torque-limiting assembly for limiting the torque applied to the mechanical support upon full engagement of the component.

  • Patent number: 4799875
    Abstract: A toroid forming machine has a plurality of individual laterally flexible dough forming members mounted upon a conveyor chain to revolve about spaced sprockets, the forming members being drawn through a stationary sleeve formed by opposing one-half sleeve members from a substantially flat initial configuration to a substantially closed cylindrical configuration at an exit end of the sleeve. A stationary mandrel is provided centrally of the sleeve to allow molding of dough strips between the forming members and mandrel into toroid configuration suitable for making bagels. End portions of the mandrel and sleeve are removable and have an expanding configuration to allow for varying the size of toroids exiting the sleeve. The forming members and the associated conveyor chain are easily removed for replacement by different size members as are the mandrel and sleeve members.

  • Patent number: 4336010
    Abstract: An apparatus produces a continuous plurality of generally rectangular dough elements of a controllable weight from a continuous and irregular mass of dough. The invention includes separate forming, dividing, and cutting portions. The forming portion includes multiple rollers disposed both normal to as well as parallel and traverse to the path of movement of the dough which form the irregularly-shaped dough mass to have a uniform width, depth, and consistency. The dividing portion includes a horizontally-disposed, multichannel dividing drum and a plurality of compression rollers which divide the dough from the forming portion into multiple strips of uniform cross section. The cutting portion includes a multiblade assembly having the shape of and being occludable with the channels of the multichannel drum. The blades are driven at constant speed in a planetary fashion whereby the only motions of the blades relative to the strips of dough passing through multichannel drum are inward and outward.

  • Patent number: 4218207
    Abstract: Dough-dividing and forming apparatus particularly adapted for forming toroid-shaped articles such as bagels, or the like, is disclosed. A first rotary plate member containing a plurality of cylindrical openings receives a cylindical ribbon of dough into the openings and shears the dough into disc-shaped dough lumps. The dough lumps are subsequently flattened in the center to form a web and pierced to form a generally annular shape. During the piercing operation, the dough lumps are transferred to a second rotary plate member carrying a plurality of tapered, cylindrical forming cups. As the second plate member is indexed between rotary positions, a plurality of cylindrical mandrels are repeatedly thrust into and out of the forming cups to roll the dough lumps internally along the length of the forming cups whereby the desired shape is formed.

  • Patent number: 4202221
    Abstract: Indexing apparatus is disclosed whereby a constantly rotating drive shaft can intermittently drive apparatus driven thereby. An arm carried by the drive shaft pivotally carries a second arm which has means for engaging a cammed surface whereby the pivoted arm is moved radially toward and away from the drive shaft. The rotated output member is mounted for rotation about the longitudinal axis of the drive shaft and includes a projection adapted to be engaged selectively by an engaging member on the pivoted arm as the pivoted arm is rotated in response to the positioning of the camming surface. In the preferred embodiment, the projection is an extended member and the engaging member is initially brought into contact close adjacent the drive shaft and moved radially outward in a decreasing amount whereby the rotated member is smoothly accelerated. Correspondingly, upon disengagement, the engaging member is moved radially outward in an increasing amount to smoothly decelerate the rotated member.

  • Patent number: 3986446
    Abstract: A dough proofing apparatus is for use in association with a dough forming apparatus having a dough piece receiving means which receives preformed dough pieces from a dough dividing machine and directs them toward a toroid forming apparatus wherein the proofing apparatus includes dough conveyance means for receiving and conveying dough pieces in a proofing mode of travel through a closed loop path of travel of the conveyor belt between generally adjacent dough entry and dough exit locations on the toroid forming apparatus. The conveyance belt is passed over vertically spaced pulleys with dough pieces retained thereon by adjacent dough support means on the conveyance belt which cooperate to form open-ended cage-like dough retaining receptacles for dough pieces as they travel on the conveyance means over and about the vertically spaced pulleys.
