  • Patent number: 9939170
    Abstract: The rapid thermal cycling of a material is targeted. A microfluidic heat exchanger with an internal porous medium is coupled to tanks containing cold fluid and hot fluid. Fluid flows alternately from the cold tank and the hot tank into the porous medium, cooling and heating samples contained in the microfluidic heat exchanger's sample wells. A valve may be coupled to the tanks and a pump, and switching the position of the valve may switch the source and direction of fluid flowing through the porous medium. A controller may control the switching of valve positions based on the temperature of the samples and determined temperature thresholds. A sample tray for containing samples to be thermally cycled may be used in conjunction with the thermal cycling system. A surface or internal electrical heater may aid in heating the samples, or may replace the necessity for the hot tank.

  • Patent number: 5980181
    Abstract: An apparatus for applying a wraparound cover to a pad includes a loading station, a creasing station having a pair of knife edges and an anvil for applying a pair of parallel creases in the cover, a gluing station for applying a bead of glue to an under side of the pad and a folding station for folding an overlap portion of the cover about the rear and underside of the pad so as to engage the glue bead. The folding station includes a holddown mechanism and an articulated hand that folds the cover overlap portion at each crease about the rear edges of the pad.

  • Patent number: 5286016
    Abstract: An apparatus for inserting chipboard or cardboard spacers within a lapstream of paper sheets exiting a press on a lapstream conveyor includes a chipboard ejector for firing chipboards toward the lapstream conveyor in a direction which is opposite that of the conveyor. A plurality of vacuum feet are positioned over the conveyor and are responsive to a control pulse issued by a programmable counter to pick up the leading edge of selected sheets in the lapstream. Simultaneously, the chipboard ejector fires a chipboard, in response to another control pulse from the counter, toward the point on the conveyor over which the sheet is being picked up. The vacuum feet are then released, dropping the selected paper sheet and the chipboards are thus reliably inserted at regular intervals within the lapstream. Multiple chipboards can be inserted in a single location by varying the length of the chipboard ejector control pulse.

  • Patent number: 4263702
    Abstract: A quartz resonator is made from a chemically polished quartz plate. The plate is placed in an enclosure fitted with at least three mounting clips to receive the plate. The plate is secured to the clips with an electrically conductive adhesive capable of withstanding operation at 350 degrees C. The assembly is cleaned and a metallic electrode deposited onto the plate until the desired frequency is reached. The enclosure is then hermetically sealed. The resulting resonator can consistently withstand extremely high shocks.

  • Patent number: 4171231
    Abstract: Aqueous acidic coating solutions are described for treating zinc or zinc alloy surfaces comprising trivalent chromium as substantially the only chromium ion present, fluoride ion, an acid other than nitric acid, and an oxidizing agent. The coating solutions containing trivalent chromium as substantially the only chromium ion present preferably are prepared by reducing an aqueous solution of hexavalent chromium with sufficient reducing agent to reduce all of the hexavalent chromium to trivalent chromium. Chromate coatings on zinc and zinc alloy surfaces are produced by contacting said surfaces with an aqueous acidic solution of the invention.
