Abstract: In one implementation, a universal translator device for translating protocols, the device includes one or more peripheral device interfaces through which communication from one or more peripheral devices is received using any of a plurality of protocols; a protocol translator that is (i) preconfigured with translation mappings to translate between each possible permutation of the plurality of protocols and (ii) programmed to translate, using the translation mappings, signals received from the peripheral devices into at least one target protocol; and a wireless interface that is configured to transmit wireless signals in the target protocol, the wireless signals having been translated into the target protocol by the protocol translator.

Abstract: A flow control device for an HVAC fluid transportation system includes a sensor module and a logic module. The sensor module includes a flow measurement system to be connected with a flow tube and measures a volumetric flow of a fluid through the flow tube. The sensor module further includes a first electronic circuit connected electrically to the flow measurement system. The logic module is connected to the sensor module and includes a control signal output terminal and a second electronic circuit connected to the first electronic circuit. The second electronic circuit generates and applies on the control signal output terminal an actuator control signal, using the volumetric flow of the fluid measured by the flow measurement system, for an actuator, arranged outside the flow tube of the flow control device, to actuate a valve of the HVAC fluid transportation system.

Abstract: The invention relates to a holding furnace comprising a metering device for molten metal, especially for precisely metering molten light metal during die casting, wherefore the holding furnace is provided with a dosing chamber encompassing a controlled discharge valve.

Abstract: A mounting system for one or more traverse cylinders of a die cast machine positions the cylinders behind the movable platen on a side out of the die area between the platens. A horizontally extending cylinder support bar is mounted between the ends of the lower tie bars. A traverse cylinder is mounted between the support bar and movable platen. In another embodiment, vertically extending cylinder support bars are mounted to the lower and upper tie bars on each side of the machine, with the lower ends being fixedly secured to the lower tie bars and the upper ends detachably secured to the upper tie bars. The traverse cylinders are mounted between the support bars and the movable platen.

Abstract: Method and apparatus for simultaneously welding by the stud end welding technique a stud having two or more ends. The stud includes at least one elongated relatively thin metallic projection from each end of the stud to be welded. The method and apparatus maintains a current density in a given projection sufficient to disintegrate the projection with consequent arc initiation. The resultant arcs melt all stud ends and plate. The molten ends are lowered into the pools at a controlled rate at which time the current is extinguished and the material solidifies.

Abstract: Method and apparatus for simultaneously welding by the stud end welding technique a stud having two or more ends. The stud includes at least one elongated relatively thin metallic projection from each end of the stud to be welded. The method and apparatus maintains a current density in a given projection sufficient to disintegrate only a portion of each projection with consequent arc initiation upon contact with the base metal such that the disintegration of a given projection will permit the remaining projections to contact the base metal causing a short to extinguish the one arc which has been initiated and consequent disintegration and arcing of the next tip to strike the workpiece which procedure proceeds randomly from tip to tip until the ends of the stud reach the molten metal pools.
