An accumulating vessel for use in a refrigeration system wherein a partially vaporized refrigerant is circulated therethrough. The vessel is constructed as a generally cylindrical housing having first and second end portions, and a body portion with a generally continuous circumferential inner surface, the portions together defining an internal chamber. An inlet tube opens into fluid communication with the internal chamber at a first location defining an inlet port, with an outlet tube opening into fluid communication with the internal chamber at a second location defining an outlet port. A baffle is received within the chamber intermediate the inlet and outlet ports for deflecting refrigerant from the inlet port over the outlet port. An outer surface of the baffle extends to an outer periphery configured to define at least a pair of contact surfaces with the inner surface of the body portion of the housing, and spacing the remainder of the periphery of the baffle a predetermined radial distance from the inner surface of the housing for the flow of refrigerant therebetween. The baffle is formed of a metal material having a layer of a metal alloy coated thereon forming at least a portion of the outer surface of the baffle including the contact surfaces. The metal alloy coating layer of the baffle is brazed to the inner surface of the housing along at least a portion of each of the contact surfaces joining the baffle to the housing.

A floor surface blasting apparatus is used for removing rustproof coating (blasting ) on a tank bottom surface to inspect weld lines on the bottom surface of high-capacity fuel tank. The floor surface blasting apparatus comprises a work arm which has weld line detecting sensors for detecting a weld line at the tip end and also has a blast head incorporating a suction nozzle; a work carriage which has the work arm and magnet devices incorporating a magnetic substance and travels arbitrarily on the floor surface; a transfer carriage which has a blast device for supplying blasting material to the blast head and travels arbitrarily on the floor surface; and a control device which controls the blast head so that the blast head is positioned on a weld line in accordance with the detection signal from the weld line detecting sensors and the signal of a position detecting device for detecting the position of the blast head and also makes the transfer carriage follow the work carriage.

The instant invention relates to the point welding of a highly corrosion-resistant metal cover plate to a less corrosion-resistant support and provides for the highly corrosion-resistant cover plate to be provided with holes and to be bonded at the same time to the support by a first build-up weld in the holes. The first weld layer is then covered by a second build-up weld. build-up welding is effect by means of metal-inert gas welding with wire electrode.

A method of fabricating a metal pressure vessel for a metal oxide-hydrogen battery. A straight length of metal having a generally T-shape cross section is formed into circular configuration and the abutting ends of the strip are welded together to form a ring that includes a generally circular body portion and a flange or fin which projects radially outward from the body portion. The welded ring is expnded radially outward to precisely fit the open end of the shell of the vessel and the ring is then assembled with the open ends of the shell and head with the ends of the shell and head abutting the outwardly extending fin of the ring. The ends of the shell and head are then welded to the ring to complete the assembly.

A package for holding commodities is fabricated from a multilayer compound foil material. The package includes at least one transversely extending closure seam and an opening arrangement positioned adjacent the closure seam. The opening arrangement includes at least one generally line-shaped opening section in which the compound foil is weakened in comparison to areas adjoining the opening section in order to facilitate a guided opening of the opening arrangement.

Herein described is apparatus for sealing cartons and containers, which includes using a laser beam directed at critical areas on the carton or container for inducing constant heat upon the area of a carton or container passing in front of the beam. Further described is a beam splitting system which splits the laser beam to direct it to different areas on the container being sealed or to different cartons simultaneously.

Disclosed are a method of and apparatus for making a welded metallic can body by effecting a mash resistance welding on a lapped side portion of a can body preform by means of a combination of a cooled elongated electrode and a cooled rotary electrode and, as required, with wire electrodes interposed between the lapped side portion and these electrodes. Also, disclosed are a tinfree steel welded can body and its making method wherein it is formed by a mash resistance welding on a lapped side portion of a can body preform made from tinfree steel, without requiring the removal of surface chromium film from the welded portion and its vicinity.
摘要:
Hermetic sealing of battery containers is accomplished in such containers comprising metal bodies provided with flanges by first mating the bodies so the flanges are coextensive, planar resistance welding the bodies together through the flanges and subsequently peripherally laser welding the edges of the flanges together to effect a redundant weld and an hermetic seal.
