Abstract: A method for recovering a composition enriched in 3-hydroxypropionic acid from a fermentation broth comprising 3-hydroxypropionic acid and/or salts thereof comprises the steps of: (a) providing the fermentation broth having a pH of from about 2 to about 8 comprising: 3-hydroxypropionic acid and/or salts thereof, (b) acidifying the fermentation broth; (c) reducing the total sulfate ion and phosphate ion (d) distilling the resulting reduced ion aqueous solution and (e) recovering the product.

Abstract: A method for a contactless transmission of electrical energy includes providing a leaf fastened to a wall. The leaf is hingedly mounted about a hinge axis. Providing a hinge plate pin. Providing a primary power coil fastened to the wall. Providing a secondary power coil fastened to the leaf. The primary power coil and the secondary power coil are in an inductive operative connection with each another via the hinge plate pin. Detecting an actual secondary power voltage induced in the secondary power coil. Comparing the actual secondary power voltage with a setpoint value of the secondary power voltage. Influencing a primary power applied to the primary power coil based on the comparison of the setpoint value and the actual secondary power voltage. Detecting the primary power required to achieve the setpoint value of the secondary power voltage. Triggering a signal when a predetermined primary power is exceeded.

Abstract: A system for transmitting electric power from a wall to a leaf hingeably fastened to the wall about a hinge axis includes a wall part fastened on the wall. A leaf part is fastened on the leaf. A primary coil is provided on the wall part. A secondary coil is provided on the leaf part. Primary electronics are configured to convert a power supply voltage into a primary voltage so as to act upon the primary coil. The primary voltage is suitable to generate a secondary voltage in the secondary coil by an inductive coupling. Secondary electronics are configured to convert the secondary voltage into an electric operating voltage suitable for at least one of an electric power supply mechanism and an electric consumer.

Abstract: For fast ethernet switches, a modular and scalable structure using programmable one-port communication modules is disclosed. The forwarding process is sequential and operates in a store-and-forward mode. The design follows a strictly predictable scheme. The forwarding process, the distribution logic, maximum latency and programmable functions, i.e. traffic monitoring capabilities, traffic filtering/policing capabilities and network management function capabilities are described and explained with reference to typical examples.

Abstract: A locking mechanism for connecting machine parts such as bearing rings on a support. The support includes at least one radially elastic element having a seating surface for the ring which is deflectable radially inwardly to permit assembly of the ring on the support surface and at least one locking element formed integrally with the support and acuatable between a release position wherein the snapping element can be flexed to facilitate assembly and removal of a ring on the seating surface and a locked position wherein the ring is supported in a form locking manner in the seating surface.

Abstract: A switch drive assembly includes a switch having a contact and a control shaft for actuating the contact and switching substantially currentlessly, and a drive having a drive motor, a flywheel accumulator connected to the drive motor for receiving a change from the drive motor immediately prior to a switching process, the flywheel accumulator being coupled to the control shaft for discharging during a switching process and executing a previously initiated switching process, the drive motor acting as a generator for generation of a self-sufficient voltage supply during discharge of the flywheel accumulator.

Abstract: A rolling bearing assembly has inner and outer members, rotatable with respect to one another, and defining a pair of races therebetween. Each of these members has a flange-shaped portion for mounting the respective member. A separate row of rolling bearings is provided in each of the races. The outer member is formed with separable ring-shaped portions defining the running surfaces of the two races, the separable portions forming an inwardly directed annular ridge under ajoining faces, so that the rolling elements abut the sides of the ridge. One of the rows of rolling bearings has twice as many rolling elements as the other row.
