20090056648 | Protection for Heat Transfer Oil Boiler - A heat transfer oil boiler protection to minimize heat loss and prevent heat transfer oil from deterioration includes a high-level tank disposed with vent and an oil-gas separator connected to the protection with a pipe work; and one or a plurality oil storage unit being connected in series between the high-level tank and the oil-gas separation; oil inlet pipe and oil outlet pipe to and from each oil storage unit being respectively disposed in the upper and the lower parts of the chamber therein; oil inlet pipe opening and oil outlet pipe opening being respectively provided in inverse trapezoid and trapezoid. | 03-05-2009 |
20090056649 | Boiler Protection Apparatus and Method - Apparatus and methods for protecting a boiler and heating system from damage comprising a control board having inputs and outputs, a processor having inputs and outputs, at least one ambient sensor in communication with the processor, at least one boiler sensor in communication with the processor, a power failure relay, the power failure relay being in communication with the processor wherein the power failure relay is capable of detecting power failure of the boiler, an alarm relay connected to the control board by the at least one output and which is capable of sending notification to an alarm system. When an ambient temperature detection event occurs the ambient sensor communicates with the processor and switches the control board from passive mode to monitoring mode. When a temperature detection event or a heating system malfunction occurs the boiler sensor or power failure relay or other types of sensors communicate with the processor and initiate an alarm pathway or provide a circulation mode for circulating water through a heating system of an enclosure to be heated by the boiler and heating system. The control board may provide for the boiler to return to normal function when the temperature detection event or the heating system malfunction ends. The apparatus may also be used to prevent boiler, heating system and enclosure damage by initiating other actions when a heating system malfunction occurs. | 03-05-2009 |

20110283958 | MONITORING MODULE FOR HOT WATER HEATER DIAGNOSTIC DEVICE - A monitoring module for connection to a diagnostic device having two or more light emitting sources for indicating operating fault conditions of an apparatus. The monitoring module feeds information signals to a communication link for reception at a remote location. The monitoring module is secured over a series of light emitting diodes of the diagnostic device and reproduces these for local access. The series of LED's indicate fault conditions of the apparatus which in this embodiment is a hot water heater. Accordingly, the operation of the hot water heater at its fault status can be monitored from a remote location and on site. | 11-24-2011 |

20140318480 | MAGNETIC LIQUID LEVEL GAUGE FOR BOILER DRUM WATER LEVEL MEASUREMENT - A magnetic liquid level gauge for measuring a boiler drum water level comprises an external cylinder body having a first upper portion and a first lower portion, and an internal cylinder body having a second upper portion and a second lower portion, the first upper portion and the second upper portion are connected to the boiler drum through a steam side sampling pipe, the second lower portion is connected to a water portion of the boiler drum through the water side sampling pipe, the external cylinder body and the internal cylinder body define a steam heat tracing chamber therebetween. A float inside the internal cylinder body is connected to a magnetic component in a magnetic component cylinder body. A display indicator is connected to a magnetic transmitter and a boiler drum pressure transmitter. A waveguide tube is disposed outside the magnetic component cylinder body and connected to the magnetic transmitter. | 10-30-2014 |
20160018114 | EQUIPMENT PROTECTOR WITH BUOYANT RIM - An equipment protector including a tubular body extending from a first end to a second. The tubular body is manufactured from a waterproof, collapsible material and has a first diameter. A buoyancy ring is sealingly connected to the first end of the tubular body and defines a through passage. The buoyancy ring has an outer diameter which is larger than the first diameter such that the buoyancy ring extends radially outwardly from the tubular body and is susceptible to a buoyancy force created at the exterior of the tubular body. A method of protecting equipment is also provided. | 01-21-2016 |
