  • Publication number: 20140326432
    Abstract: A heat and humidity exchanger has example application in exchanging heat and water vapour between fresh air entering a building and air being vented from the building. The heat and humidity exchanger has a self-supporting core formed from layered sheets (710, 720) of a moisture-permeable material. Plenums (750) are arranged to direct fluid streams into and out of the core. The plenums (750) may be on opposing sides of the core to permit counterflow exchange of heat and water vapour. The plenums (750) are attached to the core along opposite edges of the sheets (710, 720).

  • Patent number: 8828119
    Abstract: A membrane cartridge is manufactured by repeatedly folding and joining two strips of membrane to form a cross-pleated cartridge with a stack of openings or fluid passageways configured in an alternating cross-flow arrangement. The cartridge can be modified for other flow configurations including co-flow and counter-flow arrangements. Methods for manufacturing such cross-pleated membrane cartridges, as well as apparatus used in the manufacturing process are described. Cross-pleated membrane cartridges comprising water-permeable membranes can be used in a variety of applications, including in heat and water vapor exchangers. In particular they can be incorporated into energy recovery ventilators (ERVs) for exchanging heat and water vapor between air streams being directed into and out of buildings.

  • Publication number: 20120274030
    Abstract: A remotely actuated packing follower for compacting the packing in a base and base extension situated around a rotatable or longitudinally pulsatable shaft exiting a structure. The remotely actuated packing follower comprises a piston slidably and sealingly mounted within a housing and a packing follower cap sealingly attached to the top of the housing. The packing follower cap has a channel for fluid from a remote source to flow from a hose attached to the channel. The piston, housing, and packing follower cap create a chamber. When sufficient fluid flows into the chamber, it pushes the piston away from the packing follower cap so that the bottom of the piston can push against the packing. An inner channel in the piston accommodates the shaft. Either the remotely actuated packing follower or a traditional anti-leak fitting is optional constructed of releasably connectable sections.

  • Publication number: 20110131720
    Abstract: A wall mounted lift chair for assisting users with lowering themselves to the bottom surface of a bathtub or raising themselves out of the bathtub. The lift chair has a first frame securely attached to a wall at one end of the bathtub. A second frame is slidably adjacent to the first frame to support a seat assembly having a chair on which the user sits while moving and bathing. A lift mechanism connects the second frame to the first frame and moves the second frame between an upper position at a top edge of the bathtub and a lower position at the bottom surface of the bathtub. The seat assembly pivots outward for ease of getting on the chair and a lower chair section pivots upward when not in use. Preferably, the lift mechanism is electrically powered and the controls are on an arm member attached to the chair.

  • Publication number: 20050194025
    Abstract: Methods and compositions for cleaning and maintaining chemical, biological and radiological countermeasure washdown systems are disclosed. Systems are effectively cleaned by the removal of water scale, including deposits, sediment, microbiological scale, micro-invertebrate fouling, and the like, from the inside surfaces of piping in the system. A section of the system is isolated for cleaning and an aqueous acidic cleaning solution is circulated through the fouled pipe section to be cleaned for a sufficient time and at a controlled pH to dissolve and loosen the scale. After cleaning all of the sections, the system is restored to operational readiness.

  • Patent number: 6911283
    Abstract: A method and apparatus for coupling a pellicle to a photomask using a non-distorting mechanism are disclosed. A pellicle is coupled to a photomask with a non-distorting mechanism that is located on a pellicle frame opposite a thin film coupled to the pellicle frame. The non-distorting mechanism acts to reduce stress exerted on the photomask by the pellicle.

  • Patent number: 6803158
    Abstract: A photomask and a method for forming an opaque border on the same are disclosed. In an example method of manufacturing a photomask, no more than one patterning operation is used to form a mask field with an opaque border substantially surrounding the mask field. The border region may be substantially covered by an opaque material, and features in the mask field may be free from the opaque material. When the photomask is used to expose a pattern on an object, the opaque border may substantially prevent electromagnetic radiation (EMR) from exposing portions of the object outside the field of exposure associated with the mask field. The operation of forming the mask field may include forming an insulating clear region surrounding the features and leaving the border region outside the insulating clear region. The opaque layer may be deposited by electroplating or spraying an opaque material onto the border region.

  • Patent number: 6780548
    Abstract: The present disclosure describes an Alternating Aperture Phase Shifting (AAPS) photomask with improved transmission balance. The method includes forming an alternating aperture phase shifting photomask pattern on a substrate, including forming trenches within the substrate. The method further includes forming a transmission balancing layer over the substrate. More particularly, the method includes forming the transmission balancing layer from a material having a higher index of refraction than the substrate. In one embodiment the transmission balancing layer may be formed from spin on glass (SOG). Another embodiment of the invention may include an enhanced AAPS photomask fabricated according to the above method.

  • Patent number: 6759171
    Abstract: The present disclosure includes describes a method for fabricating an AAPS photomask with improved intensity balance. The method includes forming an alternating aperture phase shifting photomask pattern on a substrate, including forming trenches within the substrate. The method further includes forming a layer of antireflective material within the bottom of at least one trench. In one embodiment the layer antireflective material is Magnesium Fluoride (MgF2) formed using a vacuum evaporation technique. The layer of antireflective material formed at the bottom of the trench areas increases the transmission of light through the trench areas by improving light coupling into the trench.

  • Patent number: 6721695
    Abstract: A method and apparatus evaluates the runability of a photomask inspection tool that inspects plural sets of die, each die having a standard simulated industrial device feature at plural technology nodes. A technology node size is determined for each feature at which inspection by the tool provides no false detection of faults. A sensitivity module included on a photomask test plate along with a runability module allows determination of inspection tool sensitivity and runability in a single test sequence.
