Patent application number | Description | Published |
20080202083 | Grease filter - The grease filter is provided with an internal baffle to filter grease out of the air/vapor flow passing through the passages in the front face. In one embodiment, the baffle is of corrugated shape and is secured in place between two plates of the grease filter. In a second embodiment, individual baffles of tubular shape are fitted into the passages of the front face. In each embodiment, the baffles are provided with hexagonal holes that constitute an open area of from 63% to 79% of the baffle. | 08-28-2008 |
20110143643 | Vent port for a refrigerated cabinet - The vent port employs a pair of mated housing parts that define a space for two criss-crossed flap valves. Each flap valve is formed of an aluminum bracket with an aperture for the passage of air and a silicone flap that closes over the aperture. The flap valves are oriented so that gravity enhances the closing of the flaps. Resistors are mounted on the brackets to heat the brackets at a low wattage. | 06-16-2011 |
20110253695 | Electrical circuit - An indicating lamp is provided on the exterior of a vent port to indicate failure of a heater within the vent port. An electrical circuit is provided to energize the indicating lamp in response to failure of one or the other of a pair of heaters within the vent port. | 10-20-2011 |
20120042676 | Condensate evaporator for refrigeration apparatus - The condensate evaporator has a pan that is pivotally mounted on a fulcrum defined by two posts to depress the plunger of a switch as condensate collects in the pan. The switch and posts form a three point support for the pan on a flat surface. The switch is actuated by the pivoting of the pan to deliver power to a heater pad for heating the condensate. | 02-23-2012 |
20120043768 | Magnetic latch assembly - The latch assembly has a bracket that is mounted to the side of a door and a magnetic latch that is pivotally mounted on the bracket. The latch is pivotal on a protrusion on the bracket and is held in place by a bolt passing through a washer and the bracket into the door. A second smaller protrusion on the bracket is received in an identical opening in the latch that limits the degree of pivoting of the latch relative to the bracket. Upon opening of the door, the latch is gradually “peeled” away from the magnet, i.e., pivots relative to the magnet creating a gap therebetween to reduce the pulling force necessary to open the door. | 02-23-2012 |
20120181799 | Panel fastener - The housing of a panel fastener is provided with pockets along the upper edge of the elongated recess that receives a hook assembly or a pin assembly and pairs of locking elements are mounted in selected pairs of oppositely disposed pockets to engage adapters used in the foamed-in-place molding of a wall panel. | 07-19-2012 |
20120243217 | Self-contained LED tubular luminaire - The LED tube for a lighting fixture has a transparent peripheral portion, internally disposed grooves for receiving an LED array board opposite the transparent portion and externally disposed longitudinally extending slots to slidably receive connectors for the mounting of the fixture. Multiple tubes can be grouped together in arrays of two or more without requiring different fixture enclosures. | 09-27-2012 |
20120266542 | Latch assembly for a door - The latch assembly employs a coil spring for biasing a roller assembly with a main roller in a direction outwardly of the housing. The roller assembly has a pair of guide rollers or guide plates for guiding the roller assembly on the inside of the housing during use. The coil spring is positioned between the two guide rollers and remains coaxial of the housing during pivoting of the roller assembly within the housing during use. Guide pins are provided to keep the roller assembly from rubbing against the housing walls as a thrust load is applied to the main roller. | 10-25-2012 |
20130125575 | Condensate Evaporator for Refrigeration Apparatus - The condensate evaporator has a pan for collecting condensate and a heating element that is integral with the pan. The heating element includes a U-shaped copper tube and an electrically conductive wire that extends through the tube with each end thereof extending from the tube for connection to an electrical circuit. | 05-23-2013 |
20130187527 | Leg Attachment System - The leg attachment system has first component that has two plates that define a gap for receiving a plate of a second component therebetween in a snap-fit manner. The second component has a depending projection that receives a caster assembly and the lower plate of the first component has a slot to receive the projection. | 07-25-2013 |
