169091000 | MISCELLANEOUS: E.G., BLOWERS | 6 |
20080277126 | METHOD AND APPARATUS FOR SUPPRESSING SPARKS - A spark suppression device includes a plurality of blades or vanes that are mounted transversely in a duct of an air handling/dust collection system communicating with a spark source. A controlled flow of air carries sparks from the spark source through the spark suppression device. Sparks are suppressed by turbulence created in the airstream from the blades that have a downstream curvature. The turbulence strips away a hot air bubble surrounding a spark ember, thereby effectively cooling the spark and significantly reducing combustion at the spark ember. Other attributes of the invention contributing to spark suppression include an overlapping arrangement of the blades that results in high-velocity impact of the sparks against the blades, thereby breaking up the spark embers into smaller embers, and creation of rapid increased pressure within the spark suppression device that also helps to strip away the spark ember from the surrounding hot air bubble. | 11-13-2008 |
20090084562 | Filtered Cake Candle Extinguisher - A filtered cake candle extinguisher device comprises a filter, a mouthpiece connected to the filter and a decorative cover for covering filter. A sound generator may be provided to enhance the user's enjoyment while using the extinguisher device to blow out a candle or candles. | 04-02-2009 |
20090173507 | SYSTEM AND METHOD FOR REMOVING SMOKE AND HEAT FROM A STRUCTURE - Certain embodiments of the present invention provide a ventilator system and method for transferring heat and smoke from within a structure to outside the structure during a fire. The ventilator may include a housing being configured to receive heat and smoke through an intake port and expel heat and smoke through and exhaust port. The housing may have a channel between the intake port and the exhaust port wherein a motor creates airflow from the direction of the intake port to the exhaust port. The ventilator may also include an extension member having a first end and a second end. The first end may be connected to the intake port of the housing and the second end is configured for insertion into the structure. | 07-09-2009 |
20110048748 | FILTERED CAKE CANDLE EXTINGUISHER - A filtered cake candle extinguisher device comprises a filter, a mouthpiece connected to the filter and a decorative cover for covering filter. A sound generator may be provided to enhance the user's enjoyment while using the extinguisher device to blow out a candle or candles. | 03-03-2011 |
20130168112 | Filtered Blower - A filtered blower for extinguishing candles on a dessert is provided. The filtered blower includes (1) a substantially tubular body having (a) a plurality of body sections adjoined to each other along their length to form a substantially hollow space, a mouthpiece, and a nozzle, (b) a raised lip surrounding the mouthpiece, and (c) a slot within the body, between the mouthpiece and nozzle, with a first portion and a second portion, wherein the first portion retains substantially unchanged dimensions, and the second portion narrows distally from the slot to the nozzle, and (2) a screen within the slot with holes sized for allowing passage of air while filtering passage of liquid and projectiles, whereby upon a person blowing air through the filtered blower, candles are extinguished while liquid and projectiles are prevented from reaching the dessert. | 07-04-2013 |
20160158585 | Electromagnetic Fire Control System - An electromagnetic fire control system that includes a conductive surface and a power source such that the power source supplies power so that the conductive surface generates an electric field, the electric field is manipulated and interacts with a fire such that the fire is controlled. | 06-09-2016 |
