  • Patent number: 9750964
    Abstract: A fire hose coupling comprises a body having a first end connected to a fire hose and a second end having either male or female threads or, alternatively, a quarter-turn sexless coupler. The fire hose coupling comprises a recessed portion formed in an outer surface of the body. The recessed portion is shaped to define a visuotactile directional indicator such as an arrow. The recessed portion may include a light-reflecting surface to enhance visibility such as a super reflective metal film, a photo luminescent coating, or a phosfluorescent coating. The recessed directional indicator may be formed in female, male or sexless (Storz) couplings.

  • Patent number: 9752707
    Abstract: The present invention thus provides a double-jacketed lay-flat fire hose having an inner tube for conveying fluid, an inner jacket surrounding the inner tube and an outer jacket surrounding the inner jacket. The outer jacket is made of an abrasion-resistant woven fabric material that includes four longitudinal, spaced-apart and generally parallel stripes formed each of a bundle of longitudinally aligned filament yarns. This outer jacket is less prone to trapping air between the outer jacket and the inner jacket.

  • Patent number: 9294032
    Abstract: There is provided an improved roof solar panel, embodying a photovoltaic panel mounted on a frame for easy installation onto a conventional sloped roof and integration with conventional roof coverings. Such panel includes a roof covering mounting surface on an outside support of the frame, a photovoltaic panel mounting surface on an inside support of the frame, and when installed on the roof, a retainer trim for securing the roof covering and photovoltaic panel mounted on said supports while mounting to the frame. The frame also serves to provide means for securing the panel onto roof trusses. Integration with the conventional roof covering provides, inter alia, an attractive low profile with improved water shedding, wind resistance, and thermal regulation properties. The invention also relates to a kit comprising, inter alia, said roof solar panel, and to a method of installing said roof solar panel.

  • Patent number: 9103474
    Abstract: A fire hose coupling includes a substantially annular body having a first end adapted to connect to a fire hose and a second end having male threads. The annular body has a central bore. The coupling includes circumferentially spaced-apart lugs extending radially outwardly from an outer surface of the first end of the body. The coupling further includes a protective shoulder extending radially outwardly from the body between the male threads and the lugs. The protective shoulder has an outer diameter greater than an outer diameter of the male threads to thereby protect the male threads.

  • Patent number: 9019044
    Abstract: An inductive filter for a magnetron power supply lead comprises an electrically insulating tube; a power lead located partially within the electrically insulating tube, and coaxial therewith, for supplying power from a magnetron power supply to a magnetron, a first core of a first magnetic material and a second core of a second magnetic material coaxially located on the electrically insulating tube; an insulating disc of same external diameter as the first core and the second core and coaxially located on the electrically insulating tube between the first core and the second core. The inductive filter is arranged to filter noise of a first frequency band and noise of a second, different, frequency band different from being transmitted along the power lead and to absorb a predetermined transient voltage from being transmitted along the power lead.

  • Patent number: 8991116
    Abstract: There is provided an improved roof solar panel, embodying an array of photovoltaic cells mounted on conventional modular roof sheathing, that can be readily and easily installed onto a conventional sloped roof and integrated into conventional roof shingles. Such panel includes a shingle mounting surface on a perimeter area of the sheathing, a flash strip mounted inside such shingle mounting surface and, when installed on the roof, a retainer trim for securing shingles mounted on said shingle mounting surface, while mounting to the flash strip and sealing to a perimeter of a rigid transparent protective sheet over the array. The retainer trim also serves to provide means for securing the panel onto roof trusses. Integration with the conventional roof shingling provides, inter alia, an attractive low profile with improved water shedding and wind resistance properties. There is also an intermediate roof solar panel, for installation on a roof so as to provide the aforementioned improved roof solar panel.

  • Patent number: 8976542
    Abstract: A high frequency cathode heater supply for a microwave source includes a SMPS inverter and an isolation transformer having a primary winding arranged to be powered by the SMPS inverter, a monitor winding passing through primary core assemblies of the primary winding and a secondary winding arranged for connection to the cathode heater. A current monitor is arranged to monitor a current in the primary windings. Signal processing modules are arranged to receive a first input signal from the monitor winding indicative of a voltage across the cathode heater and a second input signal from the current monitor indicative of a current through the cathode heater. The signal processing modules are arranged to output a control signal to the SMPS inverter to control power supplied to the cathode heater dependent on a monitored resistance of, or monitored power supplied to, the cathode heater as determined from the first input signal and the second input signal.

  • Publication number: 20140306604
    Abstract: A low-filter is arranged for attachment to an exterior face of a wall of an electrically conducting screened chamber encasing the magnetron and an associated isolation transformer electrically connected to terminals of the magnetron. Output connections of the filter pass directly through an interface between the electrically conducting screened chamber and the filter to connect electrically, directly or indirectly, with the isolation transformer. There are therefore no electrical leads outside the screened chamber electrically connecting the filter to the isolation transformer.

  • Patent number: 8810132
    Abstract: A magnetron has an anode and a cathode. The cathode includes two parts joined by sleeves of ferrous alloy spaced by a sleeve of insulating material. The ferrous alloy sleeves are adapted to be connected to opposite poles of a power supply for heating the cathode. A high frequency power supply is used to heat the cathode. The ferrous alloy sleeves have a surface coating of conductive material. The currents induced by the magnetic field generated by the high frequency currents of the power supply are largely confined to the conductive coating due to the skin effect, avoiding the heating of and losses in the ferrous alloy itself which would otherwise ensue.
