  • Patent number: 6634421
    Abstract: A fluid cooling device, and a method for manufacturing the fluid cooling device, are disclosed. The fluid cooling device includes a plurality of cold plate members, each having a plurality of imperforate plate portions and perforate portions arranged in a line; and, at least one connector for connecting the plate portions together at one end thereof. The cold plate members are arranged in a stack, wherein respective plate portions of each cold plate member are in registration with perforate portions formed in its adjacent cold plate members in the stack. The fluid cooling device can provide very high heat transfer by close clearance laminar developing flow, thereby increasing the thermal performance of the fluid cooling device while maintaining low pressure drop.

  • Patent number: 6273186
    Abstract: A high-density, staggered pin fin array, and a method for manufacturing the pin fin array, are disclosed. The pin fin array includes a plurality of fin members, each having a plurality of elongated, pin-shaped fins arranged in a row; and, at least one connector for connecting the fins together, each at one end thereof. The plurality of fin members is arranged in a stack, wherein respective fins of each fin member are in registration with slots formed in its adjacent fin members in the stack. The method for manufacturing the pin fin array includes forming a plurality of fin members from a raw planar, tape, or thin layer stock, positioning the fin members relative to each other so that the respective fins of each fin member are in registration with the slots formed in adjacent fin members, and joining each fin member with the adjacent fin members.

  • Patent number: 5018711
    Abstract: A clamp for use in aligning and installing cosmetic fronts on drawers includes first and second clamp body members which have respective connecting flanges adjustably secured by threaded fasteners. Juxtaposed threaded clamping jaws allow a cosmetic front to be clamped on a drawer face. The clamp is formed from thin sheet metal material and has an offset construction which allows the drawer to be closed with the clamp installed. The thickness of the sheet metal stock material is utilized to determine the spacing between a top edge of the cosmetic drawer front and the cabinet in which it is mounted. The adjustable connecting flanges allow the clamp to clear a "sub-top" which is present in some cabinets, thus allowing the spacing between a top edge of the cabinet top or adjacent drawer front to be precisely regulated.

  • Patent number: 4938624
    Abstract: A connector body having a body portion insertable through a hole in a base sheet of material and an enlarged head portion so that the head portion will not pass through the hole. The body portion comprises spaced-apart, inflexible arms that project outwardly from the surface of the base sheet and define a slit therebetween. The sheet to be edgewise connected is received between the spaced-apart arms and a fastener is inserted in the slit, causing the edgewise connected sheet to be forced against one of the two opposing arms while the fastener is forced against the other opposing arm. Access for the fastener can be from the opposite side of the base sheet to which the edge connected sheet is attached through an aperture extending through the head portion and communicating with the slit or, in another embodiment, can be from the same side of the base sheet to which the edgewise connected sheet is attached. The fastener can be a screw, a resilient or rigid wedge, or a chemically expansive compound.

The body portion comprises spaced-apart, inflexible arms that project outwardly from the surface of the base sheet and define a slit therebetween. The sheet to be edgewise connected is received between the spaced-apart arms and a fastener is inserted int the slit, causing the edgewise connected sheet to be forced against one of the two opposing arms while the fastener is forced against the other opposing arm. Access for the fastener can be from the opposite side of the base sheet to which the edge connected sheet is attached through an aperture extending through the head portion and communicating with the slit or, in another embodiment, can be from the same side of the base sheet to which the edgewise connected sheet is attached.

  • Patent number: 4293816
    Abstract: A search loop for a metal detector is described having a magnetic flux feedback coil whose magnetic flux opposes that of the transmit coil to provide a balanced loop. The balanced loop is thereby nulled and produces no output signal on the receive coil when such loop is positioned in air remote from the ground and no metal object is present. The transmit coil, the feedback coil and the receive coil are supported coplanar with each other and the feedback coil is supported on the receive coil so that it is concentric therewith. As a result of supporting the feedback coil on the receive coil, there is no relative movement between these two coils due to temperature changes or mechanical stress. Such movement tends to produce false output signals in the receive coil. In the preferred embodiment the feedback coil and the transmit coil are circular and are positioned concentric with a surrounding circular transmit coil.
