Abstract: A pressure accumulator includes an accumulator housing having first and second ports for receiving first and second pressure mediums, respectively, a movable separating element subdividing an interior of the accumulator housing into at least first and second working spaces, the first working space accommodating the first pressure medium and the second working space accommodating the second pressure medium, wherein the first port is in fluid communication with the first working space and the second port in fluid communication with the second working space. At least one sensor is operatively coupled to the first working space for measuring at least one characteristic of the first working space, and a gas generator is operative to generate a gas from ambient air, the gas generator including an outlet for outputting the generated gas, the outlet in fluid communication with the first port.

Abstract: A fitting assembly includes a fitting and a tube. The fitting has a fitting body having a straight through hole and an attachment or base port, connected to the through hole by a first passageway generally perpendicular to the through hole. The tube has an outer diameter smaller than the through hole allowing a first end of the tube to pass through the through hole. A seal is positioned in one of a circumferential slot in the tube and a circumferential slot in the through hole of the fitting body, the seal sealing a second end of the tube to the fitting body. A cover is sealingly attached to the first end of the through hole. One of the cover and the tube has a portion that extends into an intersection of the through hole and the first passageway, the portion having an aperture that prevents blockage between the attachment or base port and the second end of the through hole.

Abstract: A system for software application development comprises at least one processor configured to receive a declarative XML file defining the user interface and the database structure in one integrated file. The processor generates a database schema, user interface, API definition, PDF reports, data export/import using excel. Additionally, the processor automatically enables our unified native mobile application supporting an offline mode. The processor can render any number of extensible formats, including HTML, JSON, XML, and XML schema. On receiving a request, the processor dynamically generates output from the declarative XML file enabling hot and real-time deployment.

Abstract: An electrohydraulic actuator includes a reservoir tank having a bladder that separates hydraulic fluid from any air in the reservoir tank and includes a sensor system that detects when the hydraulic fluid is depleted from the reservoir tank.

Abstract: A cylinder assembly includes a cylinder, a nut and screw assembly, a thrust tube that extends axially from the nut and out the cylinder, a drive assembly mounted to the cylinder for rotating the screw to effect axial translation of the nut relative to the screw, thereby causing the thrust tube to axially extend or retract relative to the cylinder, and an anti-rotate feature for restricting rotation of the nut relative to the cylinder. The anti-rotate feature may include a guide member coupled to the nut and including at least one key on one of the guide member or the cylinder and at least one corresponding slot on the other of the guide member or the cylinder that engages on the key. The guide member may be allowed limited movement relative to the nut and/or the cylinder thereby preventing binding of the nut relative to the cylinder.

Abstract: A method of forming a trench drain including a step of positioning a plurality of form members including a first form member and a second form member, each having at least one set of openings arranged in a generally vertical manner. The sets of openings include a first opening, a second opening and a third opening. There is a vertical distance from the first opening to the second opening that is substantially equal to a vertical distance from the second opening to the third opening. The first form member is substantially parallel with the second form member. The set of openings of the first member are aligned with the set of openings of the second form member. An opening in the first form member and a corresponding opening in the second form member are selected dependent upon a predetermined slope for the trench drain thereby defining a selected opening in each of the first and second form members. The first form member is connected with the second form member by way of a cross member.

Abstract: A modular header body is described for distributing fluid to an individually pumped fluid circuit. The modular header body has a valve to selectively isolate the header body's suction chamber from its volute, which permits a pump motor to be disconnected from the header body while the valve is closed. Each modular header body is constructed so that adjacent header bodies can be connected to each other to form a common suction chamber. Each header body's isolation valve operated independently so that the volute of one header body can be isolated from the common suction chamber without affecting fluid supply to the other header bodies.
