20100095836 | Slip Seal Diaphragm For Spring Brake Actuator - A brake actuator system of a vehicle comprising a diaphragm design with a hole and sealing element in the center. The design allows for the sealing element to seal and slide on the outer diameter of the center pushrod for the exposed length. This eliminates the need for a fixed joint to permanently attach the diaphragm to the center pushrod, and allows for the pushrod to be attached to the spring piston or a separate fixed plate and reduces stress of the diaphragm at its interface. | 04-22-2010 |
20110132189 | Vibration/Shock Resistant Stud Housing - A brake stud housing assembly and method of construction of such assembly for vehicles that exhibits increased shock resistance and vibration reduction capability, allowing for increased durability of a brake housing assembly. The housing assembly includes a vibration dampening layer having an adhesive material that provides a permanent connection between the housing shell and reinforcing plate, which transfers both tensile and compressive loading forces between the housing shell and reinforcing plate in order to reduce vibration and stress. | 06-09-2011 |
20130239799 | Spring Brake Actuator with a Caging Bolt Bearing Joining a Pressure Plate and Actuator Tube - A pneumatic brake actuator has a housing and a divider that divides the housing into a spring chamber containing a spring and a pressure chamber. The divider has an opening that receives an end of an actuator tube. A bearing that is positioned within the opening in the divider is joined to both the divider and the actuator tube. A caging bolt has a first end positioned within the actuator tube and extends from the first end through openings in the hearing and housing to a second end positioned outside of the housing. The connection between the bearing, divider and actuator tube contains the spring within the housing in the event that the housing and/or divider fails. The divider can be a piston or a diaphragm and pressure plate. The bearing can be joined to either of the divider and actuator tube with threads and/or by welding. | 09-19-2013 |
20130292216 | Pneumatic Brake Actuator with Flow Insensitive Two Way Control Valve - A pneumatic brake actuator has a spring brake actuator with spring and spring brake pressure chambers, and a service brake actuator with service brake pressure and pushrod chambers. A control valve has a seal that is moveable between an open position and a closed position for regulating fluid flow between the spring chamber and service brake pressure chamber. A first surface of the seal is in fluid communication with the service brake pressure chamber and a second surface of the seal is in fluid communication with a valve chamber that is not in fluid communication with the service brake pressure chamber or spring chamber. The seal moves between its open and closed positions based on a pressure in the service brake pressure chamber. Movement of the seal is not dependent on the rate of flow of fluid between the spring chamber and the service brake pressure chamber. | 11-07-2013 |
20150144440 | PNEUMATIC BRAKE ACTUATOR WITH FLOW INSENSITIVE TWO WAY CONTROL VALVE - A pneumatic brake actuator has a spring brake actuator with spring and spring brake pressure chambers, and a service brake actuator with service brake pressure and pushrod chambers. A control valve has a seal that is moveable between an open position and a closed position for regulating fluid flow between the spring chamber and service brake pressure chamber. A first surface of the seal is in fluid communication with the service brake pressure chamber and a second surface of the seal is in fluid communication with a valve chamber that is not in fluid communication with the service brake pressure chamber or spring chamber. The seal moves between its open and closed positions based on a pressure in the service brake pressure chamber. Movement of the seal is not dependent on the rate of flow of fluid between the spring chamber and the service brake pressure chamber. | 05-28-2015 |

20080256663 | Nucleic acid molecules and other molecules associated with plants - Expressed Sequence Tags (ESTs) isolated from maize are disclosed. The ESTs provide a unique molecular tool for the targeting and isolation of novel genes for plant protection and improvement. The disclosed ESTs have utility in the development of new strategies for understanding critical plant developmental and metabolic pathways. The disclosed ESTs have particular utility in isolating genes and promoters, identifying and mapping the genes involved in developmental and metabolic pathways, and determining gene function. Sequence homology analyses using the ESTs provided in the present invention, will result in more efficient gene screening for desirable agronomic traits. An expanding database of these select pieces of the plant genomics puzzle will quickly expand the knowledge necessary for subsequent functional validation, a key limitation in current plant biotechnology efforts. | 10-16-2008 |
