IPC: H01H33/75
Filed: 1921-11-26
Abstract: 190,346. British Thomson - Houston Co., Ltd., (General Electric Co.). Nov. 26, 1921. Oil switches; sparking, preventing. - High - potential switches comprise a vessel containing an insulating fluid, for example, oil, formed with two chambers into both of which the arc is drawn at break, the resulting pressure in the first chamber serving to force oil into the portion of the arc stream in the other chamber and extinguish it. The oil vessel 10 is divided into a lower and upper part by the partition 16 which has a conical orifice 15 through which the movable contact-member 14 extends into engagement with the fixed contact 9. Passages 18 in the partition 16 and tubes 20 mounted in the partition connect the oil surrounding an insulating sleeve 17 with that in the upper chamber. When the movable contact is withdrawn into the upper chamber, an arc is drawn with it and the pressure produced in the lower chamber causes a flow of oil through the passages into the upper chamber and across the upperportion of the arc stream. The heated oil and gases are causes to take a circuitous path by the baffies 22, 23 in the upper chamber, and the gases are finally cooled before passing out of the atmosphere through the vent 12 by laysrs of quartz pebbles 25 filling the upper end of the container and retained in place by a perforated plate 26. To prevent the gases escaping around the movable contact, the contact passes through a stuffing-plate which is secured to the insulator 31 and forms the top of a stuffing-box chamber. Specification 184,666 is referred to.

Abstract: 1523945 Scan converter PRINCETON ELECTRONIC PRODUCTS Inc 2 Aug 1976 [4 Aug 1975] 32157/76 Heading H4F An incoming video signal 114 whose line rate is an odd integer submultiple (e.g. <SP>1</SP>/ 7  or <SP>1</SP>/ 9 th) of a standard television line rate, at which latter rate it is desired to display the video signal, is fed to a scan converter having a memory (e.g. a single gun storage tube) wherein alternate segments each of one television line scan period are stored (i.e. segments 116, Fig. 5b, corresponding to 1, 5, 9, 13 &c. Fig. 6c are stored), the memory being raster scanned during the intervening line scan periods (118, Fig. 5b) and the resulting signal displayed or a television monitor. Thus by causing the single gun of the storage tube to write and read during alternate line scan periods of the television raster display scanning standard instead of during alternate line scan periods of the incoming video signal (Fig. 2 and 3, not shown) a substantially flicker free display is achieved. To obtain a spatially uniform raster in the displayed image when interlaced scanning is employed the lines of the alternate television fields are offset by one line from the lines of the preceding field (Fig. 8, not shown). The incoming "video" signal may be a slow scan facsimile type signal (as shown in Fig. 5b) or a PP1 type radial scan type signal derived from radar, sonar or ultrasound scans (Fig. 6a, not shown) the time period of each radial scan (i.e. the time between the emitted energy pulses) being an odd integer submultiple of the television line scan rate.

Abstract: 1479685 Testing pressure in fire extinguishers; leak testing NU-SWIFT INTERNATIONAL Ltd. 19 July 1974 32209/74 Headings G1L and G1S To check the gas-pressure in a maintained pressure type fire extinguisher 10 in case of leakage, the interior of the extinguisher is communicated e.g. by means of a 3-way adapter 40, Fig. 1, with a source of gas 42 at a pressure known to be higher than that in the extinguisher, and with a pressure gauge 44, the combined pressure of the gases being measured by the gauge. As shown the adapter 40 is fitted on to the filling valve of the extinguisher and a valve 76 is opened so that the adapter is filled with high-pressure gas from source 42. The valve 76 is then shut. By turning a handle 64, a spindle 60 in the adapter can then be rotated to unscrew and lift the sealing plug 22 of the filling valve thereby allowing communication between the interiors of the extinguisher and the adapter 40 via grooves 31, the resultant pressure of the mixed gases, which is only marginally altered by the small volume of gas from source 42 added to the gas in the extinguisher, being measured by gauge 44. The use of a high-pressure source 42 precludes leakage of gas from the extinguisher. A bleed valve 80 may be fitted to the adapter.
