Title: Radar system
IPC: G01S13/68
Filed: 1973-11-08
Abstract: 1451353 Radio direction-finding PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 8 Nov 1973 [11 Nov 1972] 51848/73 Heading H4D A system in which pulses of E/M energy are radiated in a conically scanning beam and in which received pulses reflected from a moving target are processed to derive tracking signals, comprises two coherent receiving channel having inputs with a 90 degree difference there between. It also comprises selecting means deriving from the outputs of said channels signals of respective amplitudes x and y which correspond to received E/M energy differing in frequency from the transmitted E/M energy. Amplitude determining means operative upon said signals of amplitudes x, y derives a further signal of amplitude R=#x<SP>2</SP>+y<SP>2</SP>, from which the tracking signals are obtained as modulation of R due to the conical scanning of the beam. As described, a transmitter-oscillator 1 is coupled to a pulse modulator 2 which is, in turn, coupled via a transmit-receive switch 3 to an aerial 4. The aerial is of small beam width and is provided with means for conically scanning the beam. The aerial 4 is also coupled via the switch 3 to a receiver 5, which feeds two receiving channels 7, 8, comprising respective product modulators 9, 10 and MTI filters 11, 12. The modulator 9 has one input from the receiver 5 and another directly from the transmitteroscillator 1. The modulator 10 has one input from the receiver 5 and another from the transmitter-oscillator 1 via a 90 degree phaseshifting network 13. The outputs from the MTI filters 11, 12 are applied to a device 14 in which each is squared in a respective multiplication stage. The squared outputs from said stages are summed in a summing device and are applied to a further device which forms the square root of its input signal (Fig. 2, not shown). A device 6 derives the tracking signals from the output of the device 14, which is modulated with the scan frequency of the aerial 4. Reference is made to U.S.A. Specification 3,026,513.

The journals 15 are held in their adjusted position by engagement of pins 19 on levers 18 with a selected one of a series of holes in a fixed plate 20 on the shear frame. The correction applied by the gearing 25, 27 may keep the position of the gauging stop constant or move it forward or back in a predetermined ratio to the adjustment in cutting clearance. A further gear may be interposed between pinion 25 and segment 27. The movable blade, which may be the upper one, is actuated by cylinders 12.

Abstract: 1,065,149. Colour television tubes. SYLVANIA ELECTRIC PRODUCTS Inc. Dec. 28, 1964 [Dec. 27, 1963], No. 52571/64. Heading H1D. In a photo-resist method of forming the phosphor screen of a colour cathode-ray tube of the shadow-mask type, wherein phosphor dots are formed by exposing the screen to light from a point source passing through a refractive medium and through the shadow mask, a movable blade is provided between the light source and mask and is so shaped and moved as to provide time-varying attenuation of the light reaching the screen, the attenuation decreasing from the centre of the screen towards its periphery, to compensate for greater light intensity at the centre, larger holes in the centre of the shadow mask and greater light intensity attenuation at the edge of the refractive medium. A known practice of providing a variable density filter coating on the lens for light intensity attenuation is referred to. The movable blade 58, which may be foraminated, may be of generally cardioidal shape, see also Figs. 7 and 8 (not shown), and is mounted in a ring 69 which is both rotated and laterally oscillated by an eccentric drive wheel 83 engaging in a circumferential groove in ring 69, opposite spring- loaded idler wheels 99, 101.

Abstract: 1,207,186. Adaptive control. INTERNATIONAL BUSINESS MACHINES CORP. Dec. 5, 1967 [Dec.7, 1966], No.55162/67. Heading G3R. In addition to automatic adjustment of the gain of a closed-loop controller of a manufacturing process in dependence on process gain, delay and natural frequency computed from controller input and output signals, controller gain is also varied to maintain fluctuations of controller input or output within predetermined limits. In Fig. 1, signals 18, 20, 22 corresponding to the magnitudes of variables of a process 10, which may be papermaking, are applied to automatic controllers, such as 24, in which they are compared with desired values applied from signal generators, such as 25, so that any differences are aliminated by control of appropriate process variables through lines 12, 14, 16. Each controller, which may be analogue or digital, introduces a number of control terms which may involve present and past values of controller input and output signals, and the gain of each is automatically adjusted by signals 26, 28, 30, 32 which are produced at 34 in dependence on predetermined functions of process characteristics, such as gain, delay, and natural frequency computed at 42. A typical function is given involving present and past values of the input and output signals which are periodically sampled at a rate for control purposes which may be greater than that at which they are sampled for calculation of process characteristics. In addition, the gain controlling signals are controlled by a manuall adjustable signal 44 so that variations of the controller input or output signals can be kept within predetermined limits. A recorder 46 associated with the controller output signals is provided to facilitate such adjustment in the arrangement shown.
