| 20120060946 | MODULAR ELECTRICAL BUS SYSTEM WITH BUILT-IN GROUND CIRCUIT - A modular electrical bus system has a grounding circuit through a plurality of modular units with each unit being both electrically and mechanically connectable together via a bridge member connecting adjacent units and the main communication module. The bridge member and modular units are grounded together with a ground circuit that extends within both components. | 03-15-2012 |
| 20110225961 | Pressurized Air-Spring Return Cylinder and Pneumatic Intensifier System - A pneumatic cylinder system has a pneumatic supply at a first predetermined pneumatic pressure. A double acting cylinder is operably connected to the pneumatic supply and with a piston reciprocatingly mounted inside for retraction and extension of a piston arm connected to the piston. A high pressure pneumatic reserve chamber stores pneumatic reserve at a second predetermined pneumatic pressure that is higher than the first predetermined pressure. The high pressure pneumatic reserve chamber is operably connected to the double acting cylinder through a valve device such that when the pneumatic supply falls below a third predetermined pressure below the first predetermined pressure, the valve device opens communication between the high pressure pneumatic reserve chamber to a selected side of the double acting cylinder to selectively retract or extend the piston and the attached piston arm. | 09-22-2011 |
| 20100251159 | Modular Electrical Bus System - A modular electrical bus system for a valve manifold has a main communication module with a plurality of modular I/O units each having a plurality of I/O fittings being both electrically and mechanically connectable together via a bridge member connecting adjacent units and the main communication module. At least one of the modular I/O units is also mechanically separable from and maintains communication connection to the main communication module. One or both of the modular IO units and main communication module may have an alpha-numeric display. | 09-30-2010 |
