Patent number: 5450065Abstract: A heat-sensitive alarm trigger is used to set off a fire alarm system. The alarm circuit is triggered either when a resistance across two sensor leads, between which the alarm trigger is connected, falls below the rated trigger resistance or when an emf of a certain strength is produced between two electrodes of the trigger. The heat-sensitive alarm trigger comprises a laminate structure which includes an optionally perforated first electrode layer and a second electrode layer. A hydrated material layer is disposed between the two electrode layers. When the hydrated material is heated above a given alarm trigger temperature, moisture is given off and the barrier layer becomes sufficiently conductive so as to trigger the alarm. This is either caused by lowering the resistance of the hydrated material to below the rated trigger resistance or by producing a sufficient emf between the electrodes which have different electrode potentials.Type: GrantFiled: August 3, 1994Date of Patent: September 12, 1995Inventor: Arnold Greenfield

Patent number: 5384562Abstract: A heat-sensitive alarm trigger is used to set off a fire alarm system having an alarm circuit with a rated trigger resistance. The alarm circuit is triggered when a resistance across two sensor leads, between which the alarm trigger is connected, falls below the rated trigger resistance. The heat-sensitive alarm trigger comprises a laminate structure which includes an optionally perforated first electrode layer and a second electrode layer. A barrier material layer which is disposed between the two electrode layers has a resistance above the rated trigger resistance. A layer of hydrated material is disposed on the perforated electrode layer. When the hydrated material is heated above a given alarm trigger temperature, moisture is given off through the holes in the first electrode and, as a result, the barrier layer becomes sufficiently conductive so as to lower a resistance across the electrodes to below the rated trigger resistance.Type: GrantFiled: February 16, 1993Date of Patent: January 24, 1995Inventor: Arnold Greenfield

Patent number: 5302028Abstract: A thermometer housing of a generally cylindrical configuration is arranged for floating reception within a bathtub, with the thermometer housing including a top wall divided into a first and second semi-annular indicator surface, with an indicator arrow operative through a bi-metallic spring arranged for deflection from the first to the second indicator surface upon bathtub water elevated to a second zone of temperature to be classified as inappropriate for bathing. A stabilizer weight member is mounted to the bottom wall to maintain alignment and emergence of the housing side wall within the associated bathtub body of water.Type: GrantFiled: April 12, 1993Date of Patent: April 12, 1994Inventor: Dianna M.

Patent number: 5231377Abstract: A portable unit indicates the precise time to close a fireplace damper door. The unit comprises a housing including a power source, and an electronic circuit, and an external heat sensor. The arrangement is such that the heat sensor is placed near the firebox and senses that a fire has been lit by the heat given off. The electronic circuit then stores this information and waits until the heat is no longer present. At this time, a fire extinguished indication is displayed, and a time delay circuit activated. If a fire is restarted before the delay circuit times out, the fire extinguished status is cleared and the process started over. If a fire is not restarted, and the delay circuit does time out, then a audible indication warns that the fireplace damper can now be manually closed to save energy.Type: GrantFiled: August 19, 1991Date of Patent: July 27, 1993Inventor: Richard V. Clark

Patent number: 5200736Abstract: An assembly is disposed on a helmet for monitoring predetermined thresholds of ambient thermal condition of the helmet. Such assembly includes at least one thermistor for sensing the status of an ambient thermal condition and a signal comparator for detecting each predetermined threshold. Individual LED's visually indicate when each predetermined threshold is reached, while an audible alarm indicates when a hazardous predetermined threshold is reached. The audible alarm is further utilized to indicate if the battery voltage is under a predetermined threshold which is predicated on the breakdown voltage of a reference diode when a test switch is closed. A temperature responsive switch is also included to conserve the life of the battery by activating and deactivating the assembly about a predetermined temperature level.Type: GrantFiled: September 20, 1991Date of Patent: April 6, 1993Assignee: Cairns & Brother Inc.Inventors: Christopher E. Coombs, Gene Keohane, Robert M. Armstrong, Robert E. Gray

Patent number: 5182542Abstract: An air cleaner with a smoke alarm unit for a forced air recirculating system is disclosed. The smoke alarm unit is housed within a module that fits within the frame of the air cleaner with minimal impact on the cleaning ability of the cleaner. In a preferred embodiment of the invention, a battery capacity tester and air cleaner functionality detector are included in the module. Signals from the battery tester and functionality detector are used by the smoke alarm unit to drive an alarm generator with different signals to produce distinguishable alarms for a smoke condition, low battery condition, and an air cleaner failure. A control unit may receive any of the alarm conditions to execute different control actions in the forced air system.Type: GrantFiled: July 2, 1991Date of Patent: January 26, 1993Assignee: Newtron Products CompanyInventors: Roger Adelman, Michael S. Duty

Patent number: 5157378Abstract: A monitoring and alarm system allows a firefighter to monitor a variety of safety related parameters during firefighting activities through audible and/or visual means. The system monitors the pressure in the firefighter's breathing system and also monitors ambient temperature and motion of the firefighter. An audible alarm is activated to indicate a potential emergency situation relating to low remaining air time, impending thermal breakthrough or lack of motion of the firefighter.Type: GrantFiled: August 6, 1991Date of Patent: October 20, 1992Assignee: North-South CorporationInventors: L.
