| 092034000 | BELLOWS TYPE EXPANSIBLE CHAMBER | 8 |
| 20110197753 | CANTILEVER FEEDBACK MECHANISM FOR A PROPORTIONAL BELLOWS ASSEMBLY - A cantilever feedback mechanism includes an upper cantilever and a lower cantilever. The upper cantilever and lower cantilever have a resistance spring rate to facilitate movement of the bellows over a selected range of resistances. The upper cantilever has downwardly oriented upper cantilever stops. The lower cantilever has upwardly oriented lower cantilever stops that engage the upper cantilever stops. Mean are provided for applying a preload to maintain the lower cantilever stops and the upper cantilever stops engaged until a force urging movement exceeds the preload. | 08-18-2011 |
| 20120036995 | OVERMOLDED DIAPHRAGM PUMP - The fluid section of an air operated double diaphragm pump | 02-16-2012 |
| 092037000 | Plural bellows | 1 |
| 20120125192 | DIAPHRAGM BELLOWS PRODUCED FROM PROFILED METAL STRIP - A profiled metal strip for a diaphragm bellows is made from a strip material having at least one border which is subjected to reverse bending. Such a metal strip is wound to produce a diaphragm bellows, with abutting borders of neighboring turns being connected with one another by a material joint, such as a welding seam. | 05-24-2012 |

| 20100071544 | Fabric Fluid-Powered Cylinder - A fluid-powered cylinder for displacing an object with respect to a support surface is disclosed. The fluid-power cylinder includes a fabric enclosure having ends fastened to two end caps and forming an expandable and contractible chamber therein. The chamber has a port for selectively disposing an incompressible fluid in the chamber. The chamber is adapted to displace the object to a first position with respect to the support surface and to displace the object to a second position with respect to the support surface. | 03-25-2010 |
| 20090301292 | Fluidic artificial muscle actuator and swaging process therefor - A fluidic artificial muscle actuator consisting of an inner elastic bladder surrounded by a braided filament sleeve and sealed off on either end with end fittings. Pressurization of the actuator produces force and/or motion through radial movement of the bladder and sleeve which forces the sleeve to move axially. Both contractile and extensile motions are possible depending on the geometry of the braided sleeve. The fluidic artificial muscle actuator is manufactured using a swaging process which plastically deforms swage tubes around the end fittings, braided sleeve, and pressure bladder, creating a strong mechanical clamping action that may be augmented with adhesive bonding of the components. The swaging system includes the swaging die and associated components which are used to plastically deform the swage tube during assembly of the actuator. | 12-10-2009 |
| 20090139397 | Method of Manufacturing Bellows - Method for producing at low cost bellows which show high durability even when used in a quite reactive atmosphere. A method for manufacturing bellows includes the steps of: I: forming an untreated bellows from a flat base plate, the base plate including 15 to 30 wt % of Cr, 5 to 40 wt % of Ni, 0.9 to 6 wt % of Al, less than 1 wt % of Mo, less than 0.1 wt % of Mn, less than 0.1 wt % of C, less than 0.1 wt % of S, less than 0.1 wt % of P and a balance of Fe and an unavoidable impurity (relative to 100 wt % of the base plate); and II: heating the untreated bellows at a temperature of 750 to 895° C. in an atmosphere which contains water and hydrogen and in which the volume ratio of hydrogen to water (H | 06-04-2009 |
| 20120011998 | MEMBRANE PUMP HEAD FOR A HOMOGENIZER OR A HIGH-PRESSURE PUMP - The disclosure relates to a membrane pump head for a homogenizer or a high-pressure pump. The membrane pump head comprises at least one pump head enclosed in a pump housing. The membrane pump head also includes a product chamber with inlet and outlet for the product, as well as a hydraulic chamber in which a piston is disposed to operate. The product chamber and the hydraulic chamber are separated by a double membrane. The membrane is oriented at 15-75° in relation to the longitudinal direction of the piston. | 01-19-2012 |
| 20120090460 | ACTUATOR FOR RAISING THE FRONT HOOD OF A VEHICLE AND PEDESTRIAN PROTECTION SYSTEM FOR A VEHICLE - An actuator is provided for raising the front hood of a vehicle having at least one extension part, by whose extension movement the front hood of the vehicle can be raised or is raised. It is provided that the extension part is at least partially formed by a planar formation, which is deformable from a first shape (e.g., a starting shape) into a second shape (e.g., an intermediate shape or final shape) to raise the front hood. Furthermore, a motor vehicle is provided that has an actuator for raising the vehicle front hood and a pedestrian protection system for a vehicle. | 04-19-2012 |
