Systems and methods are disclosed herein for a pressure tolerant energy system. The pressure tolerant energy system may comprise a pressure tolerant cavity and an energy system enclosed in the pressure tolerant cavity configured to provide electrical power to the vehicle. The energy system may include one or more battery cells and a pressure tolerant, programmable management circuit. The pressure tolerant cavity may be filled with an electrically-inert liquid, such as mineral oil. In some embodiments, the electrically-inert liquid may be kept at a positive pressure relative to a pressure external to the pressure tolerant cavity. The energy system may further comprise a pressure venting system configured to maintain the pressure inside the pressure tolerant cavity within a range of pressures. The pressure tolerant cavity may be sealed to prevent water ingress.

The present disclosure generally relates to methods and apparatuses for forming cast parts having cast in features aligned with a casting core. The part is cast around a casting core within a casting shell. The casting core has a first feature that creates a corresponding second feature of the cast part. The casting core includes a third alignment feature that creates a corresponding fourth feature of the cast part spaced apart from the second feature of the cast part. A machining tool is aligned with the second feature of the cast part based on the fourth feature of the cast part. The machining tools machines the cast part to create the at least one passageway aligned with the second feature.

A method for automatically cutting off a material passage part while reducing manufacturing cost and cycle time. This method includes preparing a cutting device capable of moving in an automatic control coordinate system, placing the molded article without fixing the molded article, detecting a shape of the molded article by a sensor, acquiring a position of the material passage part in the coordinate system, determining a position of a cut spot in the material passage part as a target position in the coordinate system, moving the cutting device in the coordinate system and disposing the cutting device on a work position for cutting the cut spot, and cutting the cut spot by the cutting device arranged on the work position.

A method for producing a strip using a rapid solidification technology is provided. A melt is poured onto a moving outer surface of a rotating casting wheel, the melt is solidified on the outer surface and a strip is formed. A gaseous jet is directed at the moving outer surface and the outer surface of the casting wheel is worked with the jet. The jet comprises CO.sub.2 and at least part of this CO.sub.2 strikes the moving outer surface of the casting wheel in a solid state.

A device for machining the edges of casting strands includes one machining tool each that can be brought into contact with a longitudinal edge of the casting strand, and at least one guide element for perpendicularly applying the machining tools to the longitudinal edges. Means are provided for moving the machining tools in parallel to the longitudinal edges of the casting strands, in order to modify the relative speed between the longitudinal edges and the machining tools.

A fixed scroll compressor body includes a scroll compressor body casting. The casting has a central body portion having a plate-like base with a spiral scroll rib projecting from the base at a right angle thereto. The spiral scroll rib includes a volume between the spiraled ribs for the compressing of refrigerant. The spiral scroll rib spirals from a central region of the plate-like base to an outer wall of the central body portion. The casting further includes a first inward-protruding portion that protrudes from the outer wall into the volume. A distance that the first inward-protruding portion protrudes into the volume is greater than a thickness of the first inward-protruding portion such that removal of the first inward-protruding portion results in a first intake opening in the outer wall. The first intake opening provides a path for a flow of refrigerant into the volume.

In a continuous casting apparatus 100 for casting a stainless steel billet 3c, a long nozzle 2 extending into a tundish 101 is provided at a ladle 1 for pouring a molten stainless steel 3 in the ladle 1 into the tundish 101. Further, a nitrogen gas 4 is supplied as a seal gas around the molten stainless steel 3 in the tundish 101, and continuous casting of the stainless steel billet 3c is performed, in which, while immersing the spout 2a of the long nozzle 2 into the molten stainless steel 3 in the tundish 101, the molten stainless steel 3 is poured through the long nozzle 2 into the tundish 101 and the molten stainless steel 3 in the tundish 101 is poured into a casting mold 105.

A method for the production of castings which are permanently provided with readable information. An identification element, which has an information surface, provided with information, and a casting surface which is assigned to the casting and also provided with information, is arranged on a casting mould surface assigned to a mould cavity of a casting mould so that the information surface is covered, while the casting surface is exposed in the mould cavity. A metal melt is poured into the mould, so that, during casting or solidification of the metal melt, a firmly bonded, form-fit or force-fit connection of the identification element to the casting is produced. The information on the casting surface is reproduced in the manner of a stamp on surface of the casting. The casting is then removed from the mould and fettled.
