Abstract: An electrochemical process produces tetraalkyl 1,2,3,4-butanetetracarboxylates having alkyl groups with 1 to 6 carbon atoms. The process employs an electrohydrodimerization of dialkyl maleates having alkyl groups having 1 to 6 carbon atoms in a reactant solution with an alcohol and a conducting salt.

Abstract: A hydraulic cylinder assembly includes a hydraulic cylinder, a motor for driving an adjustable pump, the pump, and a pivot angle control system for the pump. The pivot angle control system has at least one adjustment piston for adjusting the pump and an electrically controllable valve for controlling the adjustment piston. At least one conveying direction of the pump and thus a movement of the hydraulic cylinder is controllable via the pivot angle control system. The hydraulic cylinder assembly further includes an electrical control unit for operating at least the motor and the valve and an uninterruptible power supply, configured such that, in the event of a failure of a power supply for the control unit, at least the control unit can be supplied with electrical power from the uninterruptible power supply.

Abstract: The present invention embraces compositions comprising at least two RNA replicons (self-amplifying RNA vectors (saRNAs or rRNAs)) that can be replicated by a replicase of a self-replicating virus, e.g., a replicase of alphavirus origin. Of the at least two replicons, at least one of which optionally comprises an open reading frame encoding for the RNA-dependent RNA polymerase or replicase that is able to replicate each of the at least two replicons. Further, each replicon comprises an open reading frame encoding for different antigens of interest, e.g., different antigens derived from the same or from different pathogenic organisms, for example the glycoprotein and nucleoprotein of Ebola virus.

Abstract: A two-stage process produces tetraalkyl 1,2,3,4-butanetetracarboxylates having alkyl groups with 1 to 6 carbon atoms starting from tetrahydrophthalic anhydride (THPA). The process starts with an oxidation of tetrahydrophthalic anhydride (THPA), followed by a subsequent esterification of the resulting 1,2,3,4-butanetetracarboxylic acid with an alcohol having 1 to 6 carbon atoms.

Abstract: An ultrasonic welding device includes a sonotrode with a sonotrode surface, a lateral slide with a lateral slide surface, a touching element with a touching surface and an insertion chamber for inserting joining parts. The insertion chamber is defined in a first axial direction (y) on a first side by the sonotrode surface and in a second axial direction (x) on a second side by the lateral slide surface and on a third side opposing the second side by the touching surface. Furthermore, the ultrasonic welding device includes a first receiving element with a first stop edge and a second receiving element with a second stop edge. The first receiving element and the second receiving element are arranged to be movable in relation to each other between a starting position and an end position.

Abstract: An ultrasonic welding device includes a sonotrode, an anvil, a touching element, a lateral slide, a stop element and a receiving chamber in which joining partners are received and which is defined by bordering components of the ultrasonic welding device. The receiving chamber is defined on a first side by the sonotrode and on a second side by the anvil.
