  • Patent number: 11125446
    Abstract: An ultrasonic filtration device may be incorporated into or otherwise installed in an extractor hood in a cooking environment. The ultrasonic filtration device aids in the elimination and/or reduction of contaminants in the air produced as a byproduct of cooking. Particulate contaminants are bombarded with high-energy pressure waves, thereby breaking up the particulates and reducing their size until they are no longer noticeable and/or hazardous to the user.

  • Publication number: 20210204396
    Abstract: A printed circuit board assembly (PCBA) controls an electrically-initiated device (EID) in an electric field. The PCBA includes a conductive layer, a dielectric layer, and a trans-conductive layer (TCL). The conductive layer of the PCBA designated protected areas. An electrical current with a predetermined current density is impressed in the conductive layer when the PCBA is in the electric field. The TCL is a nickel-metal composite metamaterial positioned between the conductive and dielectric layers and configured to change in shape or thickness in the electric field such that the impressed current is steered away from the conductive layer and into the dielectric layer to prevent premature activation of the EID. A system includes an outer housing, power supply, an EID such as a sonobuoy or medical device, and the PCBA, all of which are encapsulated in the housing. A method is also disclosed for manufacturing the PCBA.

  • Publication number: 20180133370
    Abstract: Metal objects are treated by anodising the metal object in contact with an aqueous electrolyte, and then subjecting the anodised metal object to a reversed voltage. The anodising is performed in two stages, firstly to passivate with the formation of an oxide layer, and secondly to form regions in the oxide layer having a higher oxygen to metal atom ratio, for example pits or caps, in this oxide layer. The second stage of anodising is performed by applying a multiplicity of voltage cycles, each voltage cycle involving ramping the voltage between a lower threshold voltage and an upper threshold voltage, and then returning to the lower threshold voltage. The reversed voltage step forms a hydrous metal oxide in the regions of higher oxygen to metal atom ratio, and the oxide layer and hydrous metal oxide together constitute a surface layer which is integral with the metal object, and has ion exchange capacity.

  • Patent number: 9809894
    Abstract: In a process for anodizing a metal object (12), the metal object (12) is contacted with an anodizing electrolyte (32), and is first pre-anodized so as to grow a thin oxide film on the surface. The microscopic surface area is then deduced from electrical measurements either during pre-anodizing or on the pre-anodized surface. The metal object (12) can then be anodized. This is applicable when treating an implant to provide a surface that has the ability to incorporate biocidal material such as silver ions. The pre-anodizing uses a low voltage, for example no more than 2. V, and may take less than 120 seconds.

  • Patent number: 9738980
    Abstract: Metal objects are treated by anodizing (P, SE) the metal object in contact with an acidic solution, and then subjecting the anodized metal object to a reversed voltage (VR). The anodizing is performed in two stages, firstly to passivate (P) with the formation of a surface layer, and secondly to form pits in this surface layer (SE). The second stage (SE) of anodizing is performed at a lower voltage than the first stage (P). After the reversed voltage step (VR) the metal object is then contacted with a biocidal metal-containing solution. Biocidal metal is absorbed into the surface of the metal object, resulting in improved biocidal properties. The lower voltage of the second stage anodizing (SE) results in reduced processing time.

  • Patent number: 9649410
    Abstract: A metal implant for use in a surgical procedure is provided with a surface layer that is integral with the metal substrate, and which incorporates a biocidal material. The surface layer may be grown from the metal substrate, by anodising, and the biocidal material incorporated in it by ion exchange. Alternatively the layer may be deposited by electroplating, followed by diffusion bonding so as to become integral with the metal substrate. In either case, silver is a suitable biocidal material; and both the release rate and the quantity of biocidal material should be low to avoid toxic effects on body cells. Electropolishing the surface before formation of the surface layer is also beneficial, and this may be achieved by electropolishing.
