    摘要: Voltage-regulated power supply unit provided with first and second d.c. voltage sources of different voltage levels and first and second regulators. The first regulator delivers a stabilised output voltage. In general, the input voltage of the first regulator is derived from the first source. However, if the output voltage of the first source drops below the working voltage of the first regulator, an additional supply of energy is provided by the second source via the second regulator. A smoothing filter having a certain ripple factor, is inserted in the first source, thus increasing the efficiency of the supply unit.

    摘要: In a ship-born stable base mount is a hollow column secured in a position perpendicular to the deck plane of the ship. Means are presented for mounting a Gimbal system including two orthogonal axes on the upper end portion and a gyroscopically controlled servo drive system on the lower end portion of the hollow column. Furthermore, the stable base mount comprises transmission means controlled by the servo drive system and extending through the length of the interior of the hollow column to act on a base member to be stabilized.

    摘要: A device for making predictions and corrections in azimuth and a given second coordinate (particularly the range) of a target to be tracked from video signals detected by a pulse radar apparatus. In such a device a varying number of bits is written in a buffer register for each detected video signal. The number of storage elements of that register correspond with the number of increments into which the measuring range is divided. These increments are shorter than the pulse duration. The contents of the register are placed in the store of a computer during each transmitter pulse interval. The real target position is obtained by selection of a group of bits from the total of bit positions as written in the store during consecutive transmitter pulse intervals and by logically processing said group of bits.
