Abstract: Document spaces are used for intermediate technical documents created for a model with a displayed 3D model view. A document space is a finite volume having a location in the global three-dimensional coordinate system of the model and a reference to a technical document. A displayed document space in the displayed model view illustrates where one or more model parts, or corresponding pieces of model parts, which are included in the technical document, locate.

Abstract: To enable to display one or more drawing content, which have been created during defining one or more engineering drawings from a model which comprises one or more parts to model one or more structures, digital twins of the one or more drawing content with associated information are created and published. The associated information of the digital twin comprises three-dimensional coordinates for the drawing content in question, determined based on one or more parts, to which the drawing content relates, and identifying information of said one or more parts.

Abstract: To facilitate reading out information relating to an object, a drawing is split according to one or more splitting rules to one or more split drawings before it is outputted, a split drawing showing at least one of the objects or one or more pieces of the related information in a way other than it will be shown in the drawing.

Abstract: A process for the extraction of uranium compounds from wet-process phosphoric acid includes lowering the iron concentration of the wet-process phosphoric acid and reducing the valency of any remaining ferric iron in the wet-process phosphoric acid to ferrous iron, and then extracting uranium compounds from the wet-process phosphoric acid. The process can include separating a side stream from a feed stream of wet-process phosphoric acid, wherein the side stream has a greater concentration of the uranium compounds than the feed stream by filtration. Extracting uranium compounds from the wet-process phosphoric acid can be by ion exchange process or by solvent extraction.

Abstract: A method and device for detecting damaging sub-harmonic frequencies in a power system, and recording data or initiating protective action. A microprocessor based sub-harmonic protection relay (S-PRO) monitors system voltages and currents from voltage and current transformers on the power system that may be present in the 5 Hz to 25 Hz frequency window. The user of S-PRO has full programming control to select bandwidths of frequencies or specific frequency components of the collected system voltages and currents. S-PRO can be user programmed to either detect the sub-harmonic power quantities and record them for future use in simulations or to initiate protective action. Protective action may include initiating output contact closure on the device to shut down equipment or to initiate corrective actions to prevent damage.

Abstract: The present invention relates to a control system for selectively supplying electrical power in a remote environment. The system comprises a plurality of electrical circuits, each designed to operate over a unique frequency passband. Power transmitted within the frequency passband of a circuit is filtered through that circuit to power a corresponding remote device. One or more remote devices can be simultaneously powered by transmitting power within the frequency passbands of the corresponding circuits. It is advantageous to design relatively narrow passbands to accommodate a relatively large number of circuits and corresponding devices for remote operation and a triac, rectifier or other suitable turn-on gate can be incorporated into each circuit to effectively control the width of the frequency passband of each circuit. Alternatively, an operational amplifier could be used.

Abstract: An electrical control system for vehicles has a plurality of separate control modules which communicate via a communication bus and an operational program is installed in each of the modules so that all modules contain programming for the functions of each module. A programming and diagnostic system including a PC and a program connects into the bus so as to download the program from one of the modules for generating, modifying and viewing program logic steps using ladder logic which is then converted back Into an operating program format for communication to the modules. In addition, the status of the inputs and outputs of the modules of the apparatus can be displayed and forced using the programming and diagnostic system.

Abstract: An electrical control system preferably for vehicles such as a transit vehicle is arranged with a plurality of separate modules each receiving input from a series of inputs and each providing a series of outputs so that the modules combined receive inputs from all of the control, transducer and other input elements of the vehicle and the modules as a whole provide output to all of the controlled elements of the vehicle. The modules communicate between one another via a communication bus and an operational program is installed in each of the modules so that all modules contain programming for the functions of each module. A replacement module is generic and thus can contain any operational program and thus can be used for many different designs of the system. As supplied, the module may contain an existing program or no operational program if not yet programmed.

Abstract: A sole construction for use with a boating shoe or the like comprises an outsole having a multiplicity of wave-like incisions in a traction area. The incisions are each in the form of a flattened sine wave and extend generally transverse to the longitudinal axis of the sole. A plurality of straight incisions intersect the wave-like incisions and extend substantially parallel to the longitudinal axis of the sole. The sole may further include inner and outer traction areas in which a plurality of incisions intersect wave-like incisions extending parallel to the longitudinal axis of the shoe, with the straight incisions extending substantially transverse to the longitudinal axis.
