Abstract: The disclosure relates to a suspension rod for suspending a main magnet of a magnetic resonance device. The suspension rod comprises a first end, a second end, and a thermal intercept including a thermal link thermally and mechanically connected to the thermal intercept, wherein the thermal intercept is configured for thermally connecting the suspension rod to a cold source and wherein the thermal intercept is thermally and mechanically connected to a section of the suspension rod located between the first end and the second end, wherein the thermal link is spaced from the suspension rod along a section of the suspension rod located between the thermal intercept and the second end. The disclosure also pertains to a magnet support system comprising a suspension rod and a magnetic resonance device comprising a magnet support system.

Abstract: The present disclosure relates generally to a microphone assembly. The microphone assembly has an acoustic activity detection mode of operation when the electrical circuit is clocked using an internal clock signal generator in the absence of an external clock signal at a host interface, and an electrical circuit of the microphone assembly is configured to provide an interrupt signal to the host interface upon detection of acoustic activity by the electrical circuit. The electrical circuit is configured to control the operating mode of the microphone assembly based on a frequency of the external clock signal in response to providing the interrupt signal and is configured to provide data representing the electrical signal to the host interface using the external clock signal received at the host interface.

Abstract: An application specific integrated circuit (ASIC) is used with an acoustic device. An input clock signal is received. The frequency of the input clock signal is determined, and the frequency is indicative of one of a plurality of operational modes of the ASIC. Based upon the determined frequency, an amount current provided to one or more operational blocks of the ASIC is changed.

Abstract: Molds are conveyed from the delivery end (2) of a molding machine (1) to a cooling conveyor (3) or an extractor station. By this procedure the molds (4) are principally conveyed in a direction away from the molding machine in close contact with each other on the first conveyor (5), where the pouring takes place. Then the molds (4) are conveyed back in the direction of the molding machine (1) on a second conveyor (6) running parallel to the first conveyor, on which second conveyor the initial cooling and solidification takes place. The molds with the partially cooled castings are then pushed on to a cooling conveyor (3) or an extractor station by the action of a reciprocating ejector element (7).

Abstract: The apparatus consists of a weight iron (1) with a plane bottom face designed to rest on the top side (3) of the upper mold of a two part sand mold set (2,6), and a clamping plate (4, 5) located at either side of the closed mold parts (2, 6). The bottom face (7) of the lower mold (6) rests on a transport device (8). The apparatus also includes L-shaped arms (9, 10), which pivot with respect to the weight iron (1) and the two side clamping plates (4, 5). The two L-shaped arms (9, 10) are placed opposite to each other in a vertical plane through the mold parts (2, 6). The arms (9, 10) are laterally off-set and pivot with the weight iron (1) at points (16, 17).
