  • Patent number: 10506826
    Abstract: A lockable cigarette box has a slidable collar which slides upwards and links to a cover of the box to hold the cover closed in an embodiment of the disclosed technology. Further, a locking mechanism within the slidable collar which attaches to a front side of the cover keeps the cigarette box closed and locked at times. One can use a dial, button, or other input to set a time and/or to run a program which allows the box to opened only up to a certain amount of times per unit of time (rate) and/or a certain total number of times over the course of the program. This allows a person to control the maximum number of cigarettes removed over a period of time and how fast the cigarettes are removed.

  • Patent number: 9968037
    Abstract: A short-chain hydrocarbon combustor and carbon dioxide generator installable into an existing ventilation system venting an interior grow space effects combustion of a gas supply to produce carbon dioxide on demand and maintain a desired atmospheric concentration of carbon dioxide interior the grow space. Exhaust gas producible at a high-efficiency burner is drawn through a boustrophedonic flue and passed through each of a first and second heat exchanger wherein heat is conducted into a vented airflow traveling through the existing ventilation system for discard exterior to the grow space. Condensate precipitated during cooling is collectable at a water trap, and drainable for use in the grow space. Carbon dioxide enriched exhaust gas is thereby cooled by an at least 95% reduction in heat previous to emission into the grow space. Temperature and humidity are thereby controllable within desired ranges and yield maximization enabled.

  • Patent number: 9638426
    Abstract: A gas burner safety system comprises dual sensor arrays, the first array positioned proximal to the gas burner and the second array positioned proximal to a control used to turn on and of and regulate the flame of the gas burner. The first array senses the flame components such that a flame signature is obtained when no object is placed on or above the flame and a flame image is obtained when an object is proximal to the flame. By comparing the flame signature and the flame image, a central control unit operatively connected to the sensor arrays can determine the presence or absence of an object proximal to the flame. The second sensor array is positioned to detect a human hand proximal to the control. In operation, if the flame image matches the flame signature and a human hand is not detected proximal to the control, the central control unit turns off the gas burner by causing the closure of a valve in the gas supply line to the gas burner.

    Abstract: An object of the present invention is to realize a combustion control device that reduces, when a pressure within a mixer is rapidly increased at the time of ignition of the combustion control device, the transmission of the temporarily increased pressure to a pressure sensor, that brings the pressure sensor into a non-operated state and that thereby can continue combustion in the combustion control device. Hence, a combustion control device is provided that includes: a combustion chamber which has a heat dissipation disc on a front surface and within which a combustion room is formed; a burner which is attached to the combustion chamber; a mixer which mixes a gas supplied to the burner with air; and a pressure sensor which is connected to the mixer through a pressure passage, where a pressure propagation delay means which reduces transmission to the pressure sensor caused by a temporary pressure increase within the mixer is provided partway along the pressure passage.

    Abstract: A combustion apparatus includes a fuel supply line for providing an overall fuel supply to the apparatus; a burner including multiple fuel supply lines, the supply of fuel in the fuel supply lines to the burner corresponding to the overall fuel supply in the fuel supply line to the apparatus, and a combustion volume associated with the at least one burner. A temperature sensor measures a temperature of a part of the apparatus to be protected against overheating. A pressure sensor measures pressure within the combustion volume. A control arrangement varies the fuel supplies to the burner based on the measured temperature and pressure and on an information indicative for a progress over time for a signal for a time span. The arrangement maintains the temperature of part to be protected and the pressure variations within the combustion volume below predetermined limits, while maintaining constant fuel supply to the apparatus.

  • Patent number: 8159356
    Abstract: Apparatus and methods for protecting process equipment from a fire and/or an explosion are provided. In particular, the apparatus and methods utilize Seebeck sensors or thermoelectric generators to detect the propagation of a flame front or deflagration wave within the process equipment. Upon detection of the deflagration wave, the system controller activates mitigation apparatus which may be in the form of a chemical suppressant or isolation valves in order to protect the process equipment from damage.

  • Publication number: 20120028199
    Abstract: An ignitor spark indicator 100 is described that monitors RF signals within a flame rod 25 located near a spark rod 23. The signal from the flame rod 25 is processed to provide a waveform that indicates when electrical arcing is occurring. The indication when arcing is occurring is also provided to flame-detecting equipment. The flame-proving device 60 only operates when the arcing is not produced so that the flame-detecting device 60 does not confuse the arcing with a flame reducing the false positive determinations.

  • Publication number: 20110300492
    Abstract: A method of monitoring combustion properties in an interior of a boiler of the type having walls comprising a plurality of parallel steam tubes separated by a metal membrane. First and second penetrations are provided in the metal membrane between adjacent tubes on opposite sides of the boiler. A beam of light is projected through a pitch optic comprising a pitch collimating lens and a pitch relay lens, both residing outside the boiler interior. The pitch relay lens projects the beam through a penetration into the boiler interior. The beam of light is received with a catch optic substantially identical to the pitch optic residing outside the boiler interior. The strength of the collimated received beam of light is determined. At least one of the pitch collimating lens and the catch collimating lens may then be aligned to maximize the strength of the collimated received beam.

    Abstract: A flare stack comprises an upwardly extending gas discharge duct 10 and a pilot burner 16 operative at an burner location near the open top end of the duct 10 to ignite gas discharged by way of the duct. Atmospheric samples from the burner location are delivered to a monitoring station 20 remote from the duct 10 and at ground level 12. A sensor at the monitoring station 20 is responsive to a parameter of the sample indicative of combustion at the burner location such as increased CO2 or NOx or decreased O2. An igniter is operatively associated with the sensor and arranged to light the pilot burner 16 automatically if the sensor does not detect said parameter in the sample.

Within the scope of a first diagnostic process a first value which is characteristic of a first performance quantity of the internal combustion engine ascertained at a first point in time after switching off the internal combustion engine is compared to a predefined value, and an error is identified when in the comparison it is detected that the absolute value of a first difference between the first value and the predefined value exceeds a predefined first threshold value for the first point in time. The predefined first threshold value is predefined to be smaller the longer the time since the internal combustion engine has been switched off.
