Abstract: A unitary heat exchanger device, for the transfer of total heat, comprising air-to-air heat transfer means and configured such that air may pass there through. The heat transfer means comprisesan air-to-air water vapor transfer element andan air-to-air sensible heat transfer element,the exchanger elements being in air communication with each other. The device may be used in ventilation systems which replace air exhausted from the interior of a building with fresh outside air; the use of the device under cold weather conditions may avoid or attenuate the need for using a defrost mechanism to defrost the device.

Abstract: A method and apparatus for inducing circulation of a fluid in an interior of a system between such interior and a fluid pocket. The fluid pocket is connected to a fluid access opening of the system for fluid communication between the fluid pocket and the interior of the system. The method comprises modulating the temperature of a heat transfer element in thermal communication with fluid in the pocket, between a first temperature and a second temperature. A representative fluid sample may be taken from the fluid pocket for analysis.

Abstract: An altenative face protector made of a covering body for covering at least a portion of a user's face below the eye area thereof, and attachments for attaching the covering body to a user. The face protector covers at least a portion of a user's face and it comprises a breathing vent skirt element. The breathing vent skirt element has a skirt edge, and is configured such that when the face protector is worn by the user, the breathing vent skirt element, from the tip of the nose of the user, projects outwardly and extends downwardly in such a manner that the breathing vent skirt element defines an outer wall of a nostril air pocket extending below the nostril area of the user's nose. The nostril air pocket has a lower nostril opening which is in air communication, at an upper end thereof, with the nostril area of the user's nose and, at the lower nostril opening, with the atmosphere.

Abstract: An improved boom for use in containing oil spills and the like on water comprises a flotation tube, an upper chain pocket, a skirt, and a lower chain pocket. The skirt may be made to sink by placing a chain in the lower chain pocket. The spill is contained, and buoyancy provided for the boom, by filling the flotation tube with a particulate liquid sorbent. The tube is fabricated of a mesh material pervious to both the oil and water. The skirt may be fabricated of a material pervious to water, and if so desired, to oil.

Abstract: A flight simulator kit which includes at least a simulated flight attitude control member, the simulated flight attitude control member being capable of mimicking the movements of an actual aircraft flight attitude control member. A visual display system is also provided for receiving input signals and in response thereto visually display a video simulation of a plurality of simulated aircraft flight instruments mimicking the movements and responses of actual aircraft flight instruments. The kit further includes a computer for receiving the output signals from the simulated control system and in response thereto for providing the input signals to the visual display system. The kit may be used to set up a simulator in an actual aircraft not in flight.

Abstract: An inflation system for the inflation of an inflatable flotation device wherein a gas is chargeable into a gas inflatable chamber, from a gas vessel containing compressed gas, so as to form a floatable body. The inflation system initiates or triggers the inflation of such a device by taking advantage of a pressure responsive activation mechanism; the system may additionally or alternatively exploit an electrically breakable filament trigger to initiate inflation. The flotation device may be a personal flotation device in the form, for example, of a flotation vest or it may be a flotation device such as an inflatable dingy, buoy and the like.

Abstract: The present invention, relates to a hockey stick shaft or handle having both a forward and a rear gripping zone. The gripping zones each have elongated opposed faces which are of different configuration from each other. For example each gripping zone may be provided with opposed concave and convex faces but wherein the faces of one gripping zone are disposed in reversed relative relation to the other gripping zone in order to accomodate the different gripping position of each hand of a user. A hockey stick provided with such a handle may provide a sense of a better or more comfortable feel on the gripped portion of the handle and/or a sense of a more comfortable and precise control of a blade which may be fixed to the end of such a handle.

Abstract: A glove provided with a releasable strap system for securing the glove body to a user's hand. The releasable strap system comprises a strap component and a wrist anchor component. The anchor component is able to slidably engage a wrist strap member of the strap component. The strap system releasably secures the glove body to the user's hand such that simultaneouslyi) the wrist strap member is contracted about a user's wrist andii) a backhand strap member of the strap component is diagonally tensioned across the back face of the glove body such that said central component is contracted about the user's hand.

Abstract: The present invention relates to a conduit system comprising a plurality of conduit elements wherein adjacent conduit elements may be connected together by a coupling means in flexible yet fluid tight fashion. This coupling means may provide a fluid-tight joint despite variations of temperature to which the conduit elements may be subjected. The conduit system may be conveniently used for joining conduits used for feeding water to the turbines of hydro-electric plants. The coupling means may comprise annular rings or flanges fixed on the periphery of each of the pipe ends to be joined together, the annular rings having upwardly and inwardly extending side walls. An annular-type gasket formed of a resilient material may be positioned around the periphery of the rings (e.g. in a bridging relation with same), the annular gasket being positioned in a substantially co-axial alignment with the longitudinal axis of the conduits.

Abstract: The present invention relates to a tubular section which may be constructed from a sheet having a pair of opposed edges. The opposed edges are releasably connectable such that the section may be stored in a relatively flat configuration. The screw fasteners used to connect the edges together may be restrained from rotation using for example a stringer element appropriately stabilised relative to the fasteners.

Abstract: A process is provided for the preparation of a cohesive mass of herring eggs from loose herring eggs, particularly the loose eggs of the North Atlantic herring. A cohesive mass of herring eggs may be obtained by subjecting loose herring eggs to a washing stage and subjecting washed herring eggs obtained from the washing stage to a cohesion stage. The washing stage may comprise contacting the loose eggs with a saline solution.
