Abstract: A process for the epoxidation of propene involves reacting propene with hydrogen peroxide, in the presence of a methanol solvent and a shaped titanium zeolite epoxidation catalyst in a fixed bed reactor. The process then involves recovering methanol from the reaction mixture, treatment of the recovered methanol by passing it through a bed of an acidic ion exchange resin, and recycling the treated methanol to the epoxidation reaction; as well as regeneration of the acidic ion exchange resin. Catalyst breakage can be reduced or avoided by washing the regenerated bed of an acidic ion exchange resin with methanol until the methanol exiting the resin bed has an apparent pH higher than 1.8, before methanol treated with the acidic ion exchange resin is recycled to the epoxidation reaction.

Abstract: The present invention relates to a method for starting a fuel cell stack at temperatures below the freezing point of a reaction product produced during the reaction between an anode-side fuel and a cathode-side fuel. The fuel cell stack comprises a plurality of individual cells having at least one internal cell which is arranged in the stacking direction in the interior of the fuel cell stack and an edge cell which is arranged in the stacking direction at the edge of the fuel cell stack. The fuel cell stack is connected to a cooling circuit having cooling fluid for cooling the fuel cell stack, which cooling fluid can be conducted through the fuel cell stack by a pump arranged in the cooling circuit.

Abstract: A subsea housing assembly has a subsea housing with a first and a second housing portion. The first and second housing portions have first and second electrical connections for data communication. A wall separates the first and second housing portions. The assembly has an inductive coupler with first and second coupling sections disposed in the first and second housing portions. The inductive coupler provides inductive coupling across the wall for data communication between the first and second electrical connections. The inductive coupler has inner and outer coils wherein the outer coil at least partly surrounds the inner coil and at least part of the wall extends between the inner and outer coil. Soft magnetic material is arranged around the outer coil and/or inside the inner coil such that the magnetic flux is collected and guided from the outer to the inner coil and/or from the inner to the outer coil.

Abstract: The invention relates to a horizontal circuit storage system (1) for storing storage goods carried by load-carriers. The horizontal circuit storage system has a storage zone (2) with a plurality of stacked horizontal storage planes (5). A plurality of load-carriers (6) are arranged in a row in each of the storage planes. The storage zone (2) is located between two vertical conveyers (3, 4) which interconnect the storage planes vertically in each case. The load-carriers (6) can be moved horizontally in the storage planes (5) to the vertical conveyers (3, 4) by horizontal conveyers (8) which are associated each with a storage plane (5). According to the invention, a control unit is provided in order to permit faster access to individual load-carriers and, depending on a control signal from the control unit, the storage system can be brought into a condition in which a horizontal circuit is formed for the load-carriers (6).

Abstract: A method and a device are provided for the efficient charging of a vehicle battery of an electric vehicle by a charging station of a group charging station. The connected vehicle battery, starting from an initial charge state, is charged in accordance with a calculated charge priority value until the charge state of the vehicle battery reaches a selectable charge state. The calculated charge priority values of the vehicle batteries connected at the same time to the charging stations of the group charging station determine which batteries will be charged within a charging interval.

Abstract: A transducer arrangement for a nondestructive ultrasonic material testing system has a multiplicity of ultrasound transducers which can be moved linearly or swiveled along a trajectory curve. A multiplicity of ultrasound transducers can be aligned with a point of a specimen. If the size and the focal length of the transducers prohibit an annular or similar arrangement, the transducers are divided into smaller groups. They are then arranged so that every transducer passes over each desired focal point on the specimen during movement of the transducers along the trajectory curve.

Abstract: The present invention discloses a method and an in-vivo assay system useful for the identification and testing of modulating agents as well as for the validation of therapies of neurodegenerative diseases associated with the formation of neurofibrillary tangles, in particular Alzheimer's disease. The present invention is based on the surprising finding that injection of ?-amyloid A?42 fibrils into brains of P301L mutant tau transgenic mice caused several-fold increases in the numbers and an accelerated production of neurofibrillary tangles in cell bodies predominantly within the amygdala. The induced neurofibrillary tangles occurred as early as 18 days after A?42 injections and displayed striking features of neurofibrillary tangles of several human neurodegenerative diseases, particularly Alzheimer's disease.
