Patent GB-987236-A (GB)
Title: Radar receiver
Inventor: GARFIELD WILLIAM LITTERY
IPC: G01S13/34
Filed: 1961-11-10
Abstract: 987,236. Radar interference suppression; pulse modulation systems. STANDARD TELEPHONES & CABLES Ltd. Nov. 10, 1961, No. 40395/61. Headings H4D and H4L. In a frequency modulated radar receiver, means for overcoming errors due to pulse type interference of the beat frequency signal, Fig. 1, comprises an integrating R/C circuit 1 and 2, Fig. 4, feeding the integrated signal of Fig. 2 to a clamping circuit via a linear amplifier 5. The clamping circuit comprises two aiding diodes 7 and 8, reversibly biased for large signals or with points 9 and 11 grounded for small signals and connected at their junction point to the amplifier 5, via a capacitor 6 and to an output terminal 12. Capacitor 6 is of such a value that the charge thereon follows the curve of Fig. 2 when either of the diodes are conducting-i.e. when the output of amplifier 5 has pushed the potential of the junction points of the diodes to the biasing potentials of terminals 9 or 11 and remains appreciably constant when neither of the diodes are conducting. The resulting clamped waveform from terminals 12 and 13 is as shown in Fig. 3, the frequency deviation and range reading being determined therefrom by means of a frequency counter, possibly of the cup and bucket integrator type. Specification 987,235 is referred to.

Title: Error correcting system for use with plotters, machine tools and the like
IPC: G05B19/404
Filed: 1967-09-05
Abstract: 1,142,774. Position correction system. GERBER SCIENTIFIC INSTRUMENT CO. 5 Sept., 1967 [17 April, 1967], No. 40442/67. Heading G4A. [Also in Division G3] Repeatable mechanical errors in positioning the driven part of a plotter, machine tool or like machine are reduced by using a digital computer having access to a memory device storing error values corresponding to different driven part positions to modify positioning commands for the driven part to allow for these errors. The error values may be determined using an accurate position measuring device (e.g. laser interferometer) nad may be determined at intervals along each co-ordinate or at each of a plurality of locations forming a grid. The computer may be programmed to generate the error values automatically. The correction may be effected discretely as the driven part passes given points of said grid or continuously as the driven part moves between grid points. A plotter with stepping or servomotor drives controlling lead screws for moving a pen carriage in two co-ordinate directions is described and illustrated in the drawing (not shown). Input positioning commands to the system may be derived, for example from punched paper tape, magnetic tape or an on-line data generating device.
