20090183523 | ICE MAKER CONTAMINATION CONTROL SYSTEM - An ice maker contamination control system is disclosed for decontaminating components of an ice maker, and in particular, components of an ice formation housing. The ice maker contamination control system may be configured to kill fungi, bacteria, viruses, yeast and mold. The ice maker contamination control system may include at least one ultraviolet light source adapted to be positioned in an ice formation housing of an ice maker for emitting ultraviolet light in the ice formation housing. A reflective covering adapted to be attached to at least a portion of internal surfaces exposed to the at least one ultraviolet light sources. A combined ultraviolet light mounting bracket and reflector may be included for supporting the at least one ultraviolet source in the ice formation housing of the ice maker. | 07-23-2009 |
20110027130 | ADSORPTIVE PHOTO-CATALYTIC OXIDATION AIR PURIFICATION DEVICE - An air purification system formed from an adsorptive photo-catalytic oxidation device and a method of regenerating the oxidation device is disclosed. The air purification may be configured to be installed within an air duct of a central air handling system. The air purification system may also include an ultraviolet light emitted by the ultraviolet light source to breakdown captured volatile organic compounds into elemental carbon dioxide and water vapor and to irradiate air moving past the ultraviolet light and surfaces to reduce contaminants. The ultraviolet light source may be positioned to expose the adsorptive photo-catalytic oxidation device to ultraviolet light emitted by the ultraviolet light source to breakdown captured volatile organic compounds into elemental carbon dioxide and water vapor and to irradiate air moving past the ultraviolet light to reduce contaminants. | 02-03-2011 |
20130192288 | MINI-ULTRAVIOLET LIGHT SYSTEM - A contamination control system for ductless air conditioners is disclosed. The contamination control system may be formed from one or more decontamination lamps contained within a tubular housing that is hollow and includes an internal cavity extending from the first end to the second end with at least one longitudinally extending sight window positioned between first and second tubular end regions. The decontamination lamp may be positioned within the internal cavity in the tubular housing. The tubular housing may be held in place with a mounting system including at least one tubular housing receiver in which the tubular housing is secured. The tubular housing is slidably held within the mounting system such that the tubular housing is slidable longitudinally relative to the tubular housing receivers and is rotatable within the tubular housing receivers. The decontamination lamp may be activated with a photo activated sensor. | 08-01-2013 |

20110140497 | Armrest for a chair - An armrest for a chair is provided which has an improved anti-rotation and mechanical connection between an armrest body and a frame tube of the chair. The end of the frame tube is mechanically deformed or is shaped so as to have a non-circular profile with a central opening defined by inwardly projecting arcuate surfaces of the frame tube. The armrest includes a cooperating, non-circular socket which fits onto the frame tube wherein a suitable fastener is threaded downwardly into direct, self-threading engagement with an upper opening formed in the end of the frame tube. | 06-16-2011 |
20120274119 | CHAIR BACK WITH LUMBAR AND PELVIC SUPPORTS - An office chair is provided having a back assembly which is configured to provide supplemental support to the back of a chair occupant in addition to the support provided by the primary support surface of the chair back. The chair back includes a lumbar support unit having a lumbar support pad wherein asymmetric support is provided to the left and right halves of the lumbar pad. As such, the asymmetric support loads are independently adjustable to more comfortably support a chair occupant. The chair back also includes a pelvic support pad which is disposed vertically adjacent to the lumbar support. | 11-01-2012 |
20150015052 | CHAIR BACK WITH LUMBAR AND PELVIC SUPPORTS - An office chair is provided having a back assembly which is configured to provide supplemental support to the back of a chair occupant in addition to the support provided by the primary support surface of the chair back. The chair back includes a lumbar support unit having a lumbar support pad that includes a plurality of support rings disposed one inside of the other. | 01-15-2015 |
