Title: Improvements in or relating to radars
IPC: G01S7/292
Filed: 1965-08-27
Abstract: 1,108,068. Pulse radar. C. S. F. COMPAGNIE GENERALE DE TELEGRAPHIE SANS FIL. 27 Aug., 1965 [28 Aug., 1964], No. 36897/65. Heading H4D. In a pulse radar, a video signal comprising target pulses, Fig. 3a (not shown), of approximately the same width as the transmitted pulses, narrower noise pulses, Fig. 3b (not shown), and extended clutter pulses, Fig. 3c (not shown), is passed through a delay line, Fig. 1 (not shown), having a plurality of taps 01-012, each delay line portion intermediate two taps having a delay of half the transmitted pulse width t. By suitable selection and combination of tap outputs first and second signals are produced, the first one of which contains the target pulses enhanced, the noise pulses unaffected and the clutter attenuated and the second of which is dependent on the average noise content of the video signal and is used to base limit the first signal. In the arrangement of Fig. 2, the signals at taps 06 and 07 are summed at one input of differential amplifier 21, and the signals at taps 05 and 08 are summed at the other input thereof. The output of the differential amplifier, represented by (06 + 07)-(05 + 08) is detected at 22 and applied to one input of differential amplifier 23. Similarly a signal represented by (05 + 07)- (06 + 08) is produced at the output of differential amplifier 24. This signal is subjected to full wave rectification at 25 and applied to the other input of differential amplifier 23. The output of the differential amplifier 23 is detected at 26, and after amplification is fed at terminal B1 to a display means. This output signal constitutes said first signal. The forms of the input signal to the differential amplifier 23 for a target pulse, a noise pulse and clutter are given (Figs. 4a, 4b, 4c, 5a, 5b, 5c, not shown). To produce the second signal, signals from odd taps 01, 03, 05, 07, 09, 011 are summed at the input of differential amplifier 27 and signals from even taps are summed at the other input. The tapped signals are unequally weighted, the weighting rising to a maximum for taps at the centre of the line. The output of the differential amplifier 27 is full wave rectified at 28 to constitute said second signal. The first signal at B1 still contains noise, so this is removed by subtracting a predetermined portion of the second signal from the first signal in subtracting device 12. The resulting signal may then be displayed, or after peak clipping 14, fed to signal processing means.

Filed: 1956-12-10
Abstract: 831,694. Variable resistors. CLAROSTAT MFG. CO. Inc. Dec. 10, 1956, No. 37621/56. Class 37. A card for a wire-wound variable resistor is given a discontinuous law by short-circuiting part of the winding with a primary electrical bond such as 14 and providing a vernier bond such as 16 at each junction of resistive and non- resistive sections. The section to be shortcircuited is cleaned before spraying or painting with zinc to form one or more primary bonds 14, 15 and vernier bonds 16, 17, the winding being masked so that the ends of the primary bond are at least one turn short of the required non-resistive section and the vernier bonds overlap the resistive sections by at least one turn. The junctions are then accurately defined by removing the surplus metal from the vernier bond by manual scraping or abrading with the aid of a microscope. The finished card which is of thermosetting material is then heated before being bent into circular form. It is stated that this invention minimises piling up of turns near the junction of resistive and non-resistive sections when the card is bent. The primary bond may alternatively be applied as a series of overlapping dots or in a zig-zag form. Fig. 7 shows an embodiment wherein the vernier bond is in the form of a hook at one end of the primary bond.

Abstract: 303,016. Soc. Anon. pour tous Appareillages MÚcaniques. Dec. 24, 1927, [Convention date]. Actuating by liquid pressure; full-stroke devices; air, removing; valves, arrangement of. -A pump for delivering measured quantities of liquid comprises two pistons 7, 8 in a cylinder 1 provided with a suction valve 4 and a delivery valve 22. The piston 7 is operated by rack and pinion 9, 10, and during the upstroke air or vapour in the suction pipe 3 and in the space below the piston 8 passes through valves 17, 18 in the piston 8 until the liquid rises and fills said space and closes the valve 17. The piston 8 then begins to rise until the piston 7 stops. The liquid under the piston 8 is delivered through the pipe 21 by moving the piston 7 downwards until it closes the valve 18 and then continuing the movement until the piston 8 reaches the bottom of the cylinder. During this movement the air &c. between the pistons escapes through a valve 12 in the piston '7. The upstroke of the piston 8 is limited by a stop 19 on its rod 14 engaging a fixed stop 20 on the casing. At the end of the delivery stroke the rod 14 actuates a counting mechanism 16. In the form shown in Fig. 4, the ball valve 17 is housed in a small piston closed at the top by a lift valve 40 and carrying a rod 41 slidably mounted in a groove in the piston rod 14. These rods have notches 24 and 25, 26 and 27 which, in certain positions of the rods, register to allow the passage of projections on a bolt 30 operated by the lever 31 of the rotary valve 22. When the notches 26, 27 are in register the valve can be opened for delivery of the liquid, and cannot be closed again until the notches 24, 25 are in register at the bottom of the stroke, thus ensuring a full stroke. Fractional volumes may be delivered by providing means for locking the piston 8 in one or more intermediate positions.
