20100108590 | FLUID FILTER WITH AN ATTACHMENT STRUCTURE ON AN ENDPLATE OF THE FILTERING ELEMENT - A fluid filter includes a filter element having a filtering media disposed between two endplates. One endplate includes an open flow passage that allows a working fluid to flow into or out of the media during operation. The other endplate includes a connection structure. A cover houses the filter element, and has an opening that is an inlet or outlet in fluid communication with the opening of the one endplate. The cover includes another fill opening proximate the other endplate. A cap is connected to the connection structure of the other endplate to close the opening of the cover. The cover is retained between the cap and other endplate. Generally, the attachment configuration between the cap and the other endplate of the filter element helps ensure that the filter element with the correct micron rating is installed in a filtration system. | 05-06-2010 |
20100213115 | NO FILTER NO RUN FLUID FILTRATION SYSTEMS - Improvements to “no filter, no run” fluid filtration systems are described. In one example, a filter includes a movable pin cage that has a first pre-installation position adjacent the bottom end plate and is temporarily connected thereto by a snap connection system, and a second position adjacent the upper end plate where it performs a valve interaction function. In another example, a filter includes non-centered valve pins that are rotatable relative to an upper end plate of the filter. | 08-26-2010 |

20120261355 | FILTER-IN-FILTER WITH FUNNEL SHAPED PASSAGEWAY - A parallel flow filter-in-filter design for a filter system is provided. The filter-in-filter design provides two distinctly parallel or independent flow paths within a filter assembly in a single housing or shell. The filter assembly includes a first outer filter element radially spaced apart from a second inner filter element. A centertube and a funnel shaped passageway housed within the centertube are provided in a space between the first outer filter element and the second inner filter element. The centertube and funnel shaped passageway work in tandem to provide two distinct parallel or independent flow paths within the filter assembly. The funnel shaped passageway is provided generally below the second inner filter element within the centertube. | 10-18-2012 |
20130153487 | FUEL WATER SEPARATOR FILTER WITH WATER DRAIN - A fuel water separator (FWS) filter that is configured to permit water to be drained from the water sump of the FWS filter without shutting off fuel flow to the FWS filter. A check valve is positioned between the water sump and the filter element. When the FWS filter is under vacuum (e.g. as in operation), the check valve can be closed to allow water to drain from the sump. The check valve can close automatically by floating on accumulated water in the sump until the water rises to a level where the check valve is closed. The check valve can also close by opening the drain valve of the FWS filter, which causes a differential pressure between the sump and the vacuum created in the filter element chamber, which forces the check valve to close. | 06-20-2013 |
20130157834 | COMPOSITE DISPOSABLE CENTRIFUGE ROTOR WITH REUSABLE METAL CENTERTUBE - A hybrid metal/composite centrifuge is described which can be designed and manufactured for large sizes which have traditionally been of metal construction only. The hybrid metal/composite centrifuge combines an “all composite”, fully disposable, centrifuge rotor with a reusable metal center tube which retains the rotor bearings. This design combines a fully disposable composite rotor, for example made of an incinerable plastic material, with a removable and reusable metal centertube. | 06-20-2013 |
20130180898 | FLUID FILTER ASSEMBLY WITH A FILTER CARTRIDGE AND HOUSING INTERFACE - A fluid filter assembly having a filter cartridge and housing interface to indicate whether a replacement filter cartridge is proper and desirable for the fluid filter assembly. A substantially cylindrical interface is connected to and extends from the filter cartridge and is matingly received by a bore provided in a boss of a housing of the fluid filter assembly. A means for indicating at least one characteristic of the filter cartridge is provided to ensure the replacement filter cartridge is proper and desirable for the fluid filter assembly. | 07-18-2013 |

20080211683 | METHOD AND APPARATUS FOR LOOSE WIRING MONITOR - A system is provided in which the voltage phases, neutral, and ground are monitored and an alarm is generated if specific trigger conditions are met. These conditions are indicative of a possible loose neutral, loose wiring, or general over/under voltage condition. Specific algorithms can be used to determine the possibility of a loose wiring condition, and if limits are met, various alarm modes are started. | 09-04-2008 |
20080217108 | METHOD AND APPARATUS FOR A DRIVE-THRU PRODUCT DELIVERY VERIFIER - A system for improving the efficiency of drive-through delivery systems is provided. The system can provide complete error tracking and feedback; however, partial or no error tracking and/or feedback can be provided if desired. Errors in order fulfillment can be reduced. Detailed information on product weight and delivery timing can be provided. By analyzing the weight distributions of each food item or any other suitable measurements, production quality and consistency may be monitored. By analyzing the delivery times for each food item type or any other suitable measurements, production efficiency and restaurant work flow may be measured. | 09-11-2008 |
20090027061 | METHOD AND APPARATUS FOR AN ELECTRICAL CONDUCTOR MONITORING SYSTEM - A system and method for determining the status of each monitored conductor, and optionally indicating peak current or other parameters are provided.
