Abstract: Various aspects described herein are directed to a system that develops and manages releases of software applications. The system includes a server-side branch management module to automatically create one or more branches for deployment of a software application release, a deployment repository to store one or more box sets for a plurality of artifacts for the software release, and a code repository to store the plurality of artifacts. The system may further include a release management module configured to manage continuing releases of the software application, a continuous deployment dashboard module configured to receive the plurality of box sets from the deployment repository, and one or more development modules configured to create or modify at least some artifacts of the plurality of artifacts. The plurality of artifacts are automatically tagged with respective packaging types for automatic generation of the plurality of box sets.

Abstract: A drive having an emergency closing function comprises a movable coupling device, which has an emergency spring clamped between an input-side and an output-side spring system. The emergency spring is a compression spring moved along with the coupling device. A distance of the spring systems is defined by a locking device in normal operation of the drive, wherein the emergency spring can relax for an emergency function or emergency movement of the drive after the locking device is released or unlocked. The locking device is operated or triggered hydraulically or pneumatically and/or magnetically.

Abstract: A hydraulic actuating assembly for valves for controlling process fluid flows includes a valve that is operated by an actuator and that is pre-tensioned in the direction of a closing position. The actuator has a pressure chamber which is active in the opening direction and which can be connected to a low pressure by means of three parallel relief paths. A secondary relief path, which can be activated in a test mode, is provided.

Abstract: A control device has a control drive for operating a valve or some other apparatus, for example an adjustment device for the pitch angle of a wind rotor, by means of a control element. This control drive is associated with an emergency operating device, via which the control element can be reset in the event of a disturbance, essentially independently of the operation of the control drive. This emergency operating device has an energy store, whose stored energy can be released for resetting. The emergency operating device has a piston, on one side of which the energy store acts and on the other side of which a pressure in a pressure area acts, which pressure area can be connected via a switching valve to a tank or the like, in order to release the energy stored in the energy store. In this case, the piston is designed such that it moves the control element in a resetting direction when the pressure in the pressure is relieved.

Abstract: A switching fitting arrangement includes two switching fittings actuated by a switching drive. A switching drive is implemented with an additional energy accumulator, for example a part stroke spring, which permits a part stroke test.

Abstract: Automatic test equipment for testing hydraulic/pneumatic devices which devices are included within the test system as well as those which may be attached to the test system. Object oriented programming preferably using C++ language is utilized. Abstract classes representative of characteristics of a group of devices to be tested are provided. Also provided are subclasses characteristic of types of units to be tested. Upon declaration of a specific instance of a type of unit to be tested, the abstract class is inherited into a subclass which in turn is incorporated into the unique characteristics for the declared unit to be tested. A test program is activated for the specific unit to be tested. The test program is also constructed by utilizing abstract and subclasses of information characteristic to the unit to be tested.

Abstract: A hydraulic test station useful for testing various types of hydraulic apparatus, both at the time of its manufacture and in the field. The test station includes a main console, a roll-up module on which the apparatus to be tested is mounted and an electronic system for controlling the station. The main console includes a plurality of ports. Each of the individual ports may be independently selected for purposes of testing a particular hydraulic apparatus and the specific port may be independently designated as a pressure port or a return port. A manifold is associated with each of the ports and is controllable to select those pressures and flow rates required for performing the desired test or tests on the connected apparatus.
