| titleOfInvention | Improvements in the manufacture of vacuum switching devices |
| abstract | Vacuum switching or similar devices are loaded and sealed off in a vacuum furnace with their axes horizontal rather than in a vertical orientation to allow more efficient use of vacuum furnaces. The vacuum switch comprises an evacuated envelope, an insulating component, fixed and moving electrodes that mechanically engage to perform switching and a venting arrangement or pumping port which allows the device to be vented and sealed in a vacuum furnace while the device is laid with its axis in a horizontal orientation. The pumping port can be attached to an end cap (figure 4), an electrode (figure 7) or an insulator (figure 8). The pumping port can comprise a recess having holes to allow gases to evacuate the device and braze to fill the holes; a separate part having holes that are sealed by braze or a plug (figure 6) that fits into a hole and is sealed by braze. The pumping port may also employ the principle of a U-bend or water trap (figures 9 & 10), whereby a passageway that dips down then up is filled by melted braze, sealing it against the passage of gases. |
