Title: Improvements in or relating to radar systems
Inventor: BRANDON PERCY SAMUEL
IPC: G01S13/34
Filed: 1949-08-15
Abstract: 685,625. Radiolocation. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. June 20, 1950 [Aug. 15, 1949], No. 21234/49. Class 40 (vii). In order to increase the rate at which the display may be presented in a spectrumanalysing frequency-modulated radar system, particularly one in which a P.P.I. display is used, while maintaining the resolution of selected parts of the display, the radar receiver comprises two or more channels, the first channel displaying a wide range of beatfrequency signals with poor resolution, while the second channel displays a narrow range of beat-frequencies with improved resolution, any subsequent channels presenting still narrower ranges but with correspondingly improved resolutions. In the preferred embodiment, which utilizes the principles of the invention described in Specification 685,604, the beatnotes produced by heterodyning the echo signal with the transmitted signal are applied to a first channel comprising a " gain modulator " 1GM, a " spectrum analyser " 1PR and a cathode-ray tube 1T providing a P.P.I. display which may be of the sector-scan type. The " gain modulator " comprises a gating circuit permitting the passage of beat-note signals to the spectrum analyser for one twohundredth part of each cycle of the frequencymodulation. The beat notes are also applied to a second channel comprising a gain modulator 2GM, a spectrum analyser 2PR and a cathoderay tube 2T preceded by means for selecting one-tenth of the frequency band of the signals applied to the first channel. This means comprises a mixer 2M wherein the beat notes are heterodyned with the output from a variable local oscillator 2LO and a fixed band-pass filter 2BP which passes a portion of the output of mixer 2M to the gain modulator 2GM. The gain modulator correspondingly has its modulation factor increased ten times with respect to that of modulator 1GM, so that the channel is gated on for one-twentieth part of each modulation cycle. Consequently, a selected portion of the total range of beat notes is passed by the second channel to display unit 2T; a potentiometer control gauged with the oscillator 2LO is provided to position the display correctly on the cathode-ray tube, and also to provide a marker on display unit 1T indicating the midrange of the display on the second tube. A third channel comprising local oscillator 3LO, mixer 3M, band-pass filter 3BP, gain modulator 3GM, frequency analyser 3PR and display unit 3T connected to the output of band-pass filter 2BP is also provided. In this channel the band-width is decreased a further ten times while the modulation factor is increased a further ten times so that the channel is gated on for one half of each modulation cycle. In an alternative arrangement employing two receiving channels, a single cathode-ray tube display unit is used. Automatic switching is provided to give a P.P.I. presentation of poor resolution containing an annular ring of much improved resolution.

Title: Improvements in explosion whistle-alarms
IPC: G10K5/00
Filed: 1920-07-16
Abstract: 149,292. Buell, R. D. Dec. 30,1914, [Convention date]. Void [Published under Sect. 91 of the Act]. Whistles; fluid supply.-An alarmwhistle for use with internal-combustion engines and particularly applicable to automobiles &c. has un elbowshaped mounting 1 with an outlet end 2 threaded internally or externally for attaching the whistle bell or body, and an inlet end 3 threaded externally for attaching to the engine cylinder. The sounding of the whistle is controlled by pulling a cable 32 attached to the long arm of a lever 18; this depresses the short arm 20 and forces the valve stem 14 downwards against the compression spring 16 and opens the valve 13. The whistle bell 24 of the shape shown has a sound-chamber 25, an escape opening 26, and a narrow passage or slot through which the compressed gas passes. Instead of one chamber 25, there may be two or more chambers of different volumes each provided with an opening 26 and a passage or slot, thus producing a combination of different tones.

Abstract: 642,674. Gearing for converting rotary into reciprocating motion. HAMILTON, A. E. Aug. 6, 1947, No. 21448. Convention date, Sept. 20, 1939. [Class 80(i)] [Also in Group XXIII] In a machine for surfacing strip or sheet material, a slide carrying the grinding or polishing elements is moved back and forth by a connecting rod 63, Fig. 2a, secured to a crank pin 62 on a shaft 57 mounted eccentrically in a head 55 integral with a shaft 54 which is rotated through gearing by an electric motor. A pinion 56 secured to the shaft 57 meshes with a stationary ring gear 60. The crank pin 62 is thus given a planetary motion, and a vibratory motion is thus superimposed on the reciprocatory motion of the slide. In a modification, Fig. 8, the crank pin 62 is connected by a link 170 to a block 171 adjustable by a screw 176 in one arm 172 of a bell-crank pivoted at 173, the other arm of the bell-crank being connected by a link 175 with the slide.

Converting electric energy into motion of fluids by the action of magnetic fields. Generating electricity by forcing fluid through magnetic fields.-An electromagnetic interaction pump comprises two ducts in a magnetic field, one having liquid forced through it to generate an electric current which then traverses the other duct to produce the pumping action. As shown in Fig. 1, primary duct 10 and secondary duct 15 are connected at their edges by conductors 13, 14, both ducts being situated between poles 11, 12. By altering the relative widths and heights of the two ducts, different proportional fluid speeds and pumping pressures may be obtained. Modifications are described in which more than two fluid ducts may be interleaved in height and width, and a common ductwall may be used. As shown in Fig. 4, coaxial ducts 510, 515 are situated in the radial flux between poles 511 and 512 and a core 516, the neutral areas 518, 519 being blocked. In a further modification the concentric ducts are energized by a pot magnet and are provided with helical guides of opposite directions. The pump may be used as a contra-flow heat exchanger between the two fluids.

Abstract: 532,888. Glass manufacture. CORNING GLASS WORKS. July 31, 1939, No. 22210. Convention date, Aug. 12, 1938. [Class 56] A glassworking machine comprises means for separating glass changes from a downwardlymoving stream of glass, and a device for seizing and shaping the charges, the shaped charges being delivered to a forming-apparatus in such a manner that glass scarred by the shears is not included in the articles formed from the charges. The forming apparatus comprises a chain of orifice plates 100, Figs. 1 and 2, which pass around two turrets that rotate on vertical columns, one of the turrets carrying moulds 250. The glass flows from an outlet 21<SP>1</SP>, Fig. 8, in a feeder forehearth and is cut into charges by rotating blades 23 which are constructed and operated as described in Specification 532,935. A severed charge is caught by a pair of cups 63 each carried by an arm 67. The arms are carried by a shaft 88 which is oscillated to swing the cups between the receiving position and a position shown in dotted lines, where they deposit the charge in an orifice plate 100. The arms are also moved to and from one another to open and close the cups. One of the cups has a flat face while the other, 64, Fig. 11, is provided with apertures 80 through which suction may be applied to hold the charge in place, or compressed air to deliver the charge. When the cups received a charge, they close and shape it, and then move to the delivery position where they'are opened and the cup 64 turns through a right angle to deposit the charge on an orifice plate 100. The part of a charge marked by the shears is retained in the moil which is not blown out to form the finished article. The cups may be cooled by the circulation of liquid or gas through interior channels. In another construction, the charges of glass fall between parallel rotating rollers which flatten them and deposit them over the orifices in the plates 100. The surfaces of the rollers may be plain, or one of the rolls may be formed with pockets to shape the charges. The orifice plates together with blowhead mechanism from alternate links of a horizontal chain which is constructed and operated as described in Specification 532,936. The moulds 250, Fig. 1, are carried by a turret which rotates about a vertical column 214, and they are opened and closed by the means described in Specification 532,934. After an article is blown, the mould opens and the article is carried onwards by the chain. A spring- operated arm 385 knocks the article off the orifice plate, and a scraper blade then engages the moil remaining on the orifice plate and deposits it in a cullet shoot.
