Title: Improvements in and relating to tap changing switches provided with bridging resistances for transformers
IPC: H01F29/04
Filed: 1955-03-01
Abstract: 773,830. Transformers. SMIT & COS. TRANSFORMATOREN-FABRIEK N.V., W. March 1, 1955 [Warch 13, 19541, No. 6092/55. Class 38 (2). An on load tap changing switch comprises a selector switch with two contacts 7, 8 for moving between tappings on transformer winding 1 under no load, and a change-over switch having a moving contact bar 30 connected to line 20, which when it moves to change the connection of line 20 from one selector contact, 7, to the other, 8, first reduces the value of resistances 22, 23, 24, 25 connected between. contacts 7, 8 before the connection between line 20 and contact 7 is broken and increases it afterconnection between line 20 and contact 8 is made. The contact bar 30 is of such length that when it reaches the position shown by the dotted lines 30<SP>1</SP>, resistance 25 is short-circuited, although connection between contacts 30 and 7 through contact 11 is unbroken. Similarly, resistance 23 is inserted in the circuit between contacts 7, 8 after contacts 30 and 8 are connected through contact 18. By this arrangement the circulating current is reduced when it is made and broken, and the voltage drop due to the load current in the resistances is kept down. In a modification the resistances are connected to two parallel rows of contacts, of which one in each row at opposite ends is elongated, the contacts being bridged by a moving conductor connected to the line, Fig. 4 (not shown).

Abstract: 1500693 Ultrasonic imaging systems EMI Ltd 14 Feb 1975 [15 Feb 1974] 6883/74  Heading G1G Background noise ("whiteout") in the output signal from a scanning pick-up device of an acoustic imaging system is reduced by irradiating with a fan-shaped ultrasonic beam only a narrow region of the object to be imaged, which region corresponds to the currently-scanned portion of the reflected acoustic image field at the pick-up device. The imaging system described uses a pick-up device an image converter tube of the Sokolov type, with line and frame scan. The plane of the fan-shaped ultrasonic beam is parallel to the line scan direction and the beam is swept (mechanically, or by use of a phased array) in correspondence with the frame scans of the Sokolov tube and of a display device. The ensonified region width is equivalent to several lines of the tube scan raster, so precise registration of the beam sweep and frame scans is unnecessary. The extent of the beam in the line scan direction may be reduced to be equivalent to a fraction of the line length, in which case the beam is swept also in the line scan direction.
