Title: Improvements in or relating to pulsed radar systems
Inventor: MILLER ALAN
IPC: G01S13/528
Filed: 1965-12-10
Abstract: 1,092,208. Pulse Doppler radar. MARCONI CO. Ltd. Sept. 29, 1966 [Dec. 10, 1965], No. 52652/65. Heading H4D. The Specification describes an improvement on the pulse Doppler radar described in Specification 832,135 in which pulse pairs are transmitted and has as one object to overcome the fault of said prior art in that, when the echoes are as shown in Fig. 2 (a), comprising clutter echo pairs C1 and C2, a first target echo pair E1 and E2, both in clutter, and a second target echo pair F1 and F2, with one echo F2 clear of clutter, said prior art will produce a fake additional echo due to echo F1. To ensure that a clutter echo will not include both pulse echoes of a pair, the pulse pair spacing T is made wide, e.g. 500Ás. The transmitted signal is produced by mixing the outputs of a Stalo 8, Fig. 1, and Coho 9. The echo train is converted into an I.F. signal by mixing in mixer 11 with the Coho output, and the resultant is coherently place detected at 12 and amplitude detected at 13 to give outputs 2(d) and 2(a) respectively. The outputs are each delayed by period T in means 16 and 14 to give 2(e) and 2(b). Waveforms 2(a) and 2(b) are passed to AND gate 15 to give waveform 2(c), and waveform 2(d) is subtracted from waveform 2(e) in means 17 to give waveforms 2(f). Waveforms 2(c) and 2(f are passed to AND gate 18 to give waveforms 2(g), with F1 the undesired echo. Waveform 2(g) is passed to AND gate 20, both directly and delayed by amount T as waveform 2(h), to give waveform 2(j). Pulse F, 2(j) is converted into a blanking pulse FP, 2(k) in means 21 and 22 and is used as a blanking input to one side of AND gate 24, receiving waveform 2 (f) (slightly delayed waveform 2(h)) at its other input, to remove pulse F1 from waveform 2(p) and so produce the corrected output waveform 2(m).

In use, initially the two containers 1, 5 are brought to the same level under the same pressure and the scales 2 balanced by weights 11 and the reading of the height of container 5 taken. The two containers are then exposed to their respective pressures. By means of screw 6 and crank 7 container 5 is raised or lowered until the scales 2 are again balanced. The height of container 5 is again read and the difference between these two heights gives the pressure difference in units of length of mercury column. If one pressure is to be atmospheric pressure, then the enclosure 13 may be dispensed with Fig. 1 (not shown). Use of a vernier enables the pressure to be read to an accuracy of 0À5 parts per thousand.

Title: Device for torsional oscillation testing
IPC: G01N19/00
Filed: 1974-12-16
Abstract: 1479785 Torsional oscillation testing LONZA Ltd. 16 Dec 1974 [21 Dec 1973] 54340/74 Headings G1A G1U and G1S In an apparatus for testing bodies by torsional oscillation, the maxima and minima of the oscillations and the time between them are observed to determine the period and damping of the oscillations. The invention contrasts with the more common observation of the zero crossing points of the oscillation, and is particularly applicable to testing plastics bodies where creep makes zero crossing observation unreliable. In Fig. 1, the body 1 is clamped at its lower end to a disc 2 which can be twisted by electromagnets 3, 4 to initiate the oscillations. The oscillations are observed by an optical transducer, Fig. 2, having a source 6, photovoltaic detector 8, and a fixed aperture 7 which co-operates with an aperture 5 in the disc. As the disc oscillates a corresponding varying voltage occurs across resistor 10. A control unit 24 operates the electromagnets and the various switches shown,and, with the aid of circuits 25-28 which detect when diodes 16-19 become back biased, this results in the voltages across resistor 10 at two successive maxima and their associated minima to be stored in capacitors 12-15. The time between the operation of circuits 25 and 27, which corresponds to a half-period of the oscillation is measured by circuit 24 which operates a gate 39 during this time to gate pulses from clock 40 into a counter 41; a calculator 42 uses this halfperiod and also constants representing the body dimensions and the disc's moment of inertia, to calculate the shear modulus of the body. The voltages on capacitors 12-15 are fed to inverters 43, 44 and adders 45, 46 to provide the amplitude of successive oscillations, and these are divided at 47 and the log is found at 48 to give the damping of the oscillations. The switches may be MOSFETS, and are initially operated a fixed time after the electromagnets; alternatively they may be initially operated by diodes 49, 50 in the control unit which detect the first maximum after the electromagnets have operated. In the event of a test body with substantial creep, the transducer 9 may be made to follow up the creep in a known manner.

Abstract: 1,197,899. Double belt casting machines. B. F. GOODRICH CO. 30 Nov., 1967 [30 Nov., 1966], No. 54635/67. Heading B5A A continuous flat polyurethane strip, suitable for use as belting, is cast between a pair of vertical downwardly moving conveyers 10, 13, the material being cured during its downward travel by heated platens 28 which press against the belt. The space between the belts is laterally limited by a pair of spaced apart resilient strips 30 which are drawn continuously between the belts from reels 31. The positions of the reels is adjustable so that the width of the cast strip may be varied. The distance between the belts and consequently the thickness of the strip, is varied by altering the position of belt 13 by cranks 20 which adjust the positions of idle roller 15 and driving roller 14. If desired a reinforcing web may be incorporated into the strip.

Abstract: 1,199,830. Moulding plastics. McGRAWEDISON CO. 18 Nov., 1968 [11 Dec., 1967], No. 54677/68. Heading B5A. [Also in Division G5] A laminated metal-vinyl gramophone record 10 has an internal metal layer 14 having a central hole diameter greater than and an outside diameter less than the corresponding dimensions of the finished record. In a method of making the record a thin metal strip 17, e.g. of steel, is drawn through straightening rollers 19 and degreaser 20 past a pair of sprays 21, 22 which supply a coat of zinc or iron phosphate. After drying in oven 23 the strip is primed by sprays 24, 25 which apply a vinyl primer and this is baked as the strip passes through oven 26. Layers of vinyl strip material 27, 28 preheated by heaters L1-L4 are then applied under pressure to the top and bottom of the metal strip and the laminate which is thicker than the finished record is cooled in cooler 35. The laminated strip is then fed to a combined piercing and blanking press 41 which supplies disc blanks equal in central hole and diameter size to the metal layer 14. The blank after preheating is then placed in a compression mould which compresses it to the finished record size during which the excess vinyl produced by the reduction in thickness flows past the inner and outer edges of the metal layer. The compression mould has similar upper and lower members 43, 44 carrying stamp discs 43a, 44a secured by flat headed screws 43b, 44b and formed with ducts 48 for heating and cooling the mould. Pin 47 and outer lipped edges 46 determine the hole size and outer diameter of the record.

Abstract: 1363318 Valves L V ANDERSSON 5 Dec 1972 [16 Dec 1971] 56080/72 Heading F2V In a mixing tilt-valve, e.g. for gases, when mixed gas is withdrawn through outlet 12, the consequent pressure drop in mixing chamber 5 causes unmixed gases at inlets 9a, 9b to force valve member 2 to tilt about ridge 11 as shown and thereby permit the gases to flow into the chamber 5. The ratio of the flows through the inlets is adjustable by rotating the valve member 2 relative to its seating 3 by means of a knob provided on the end of spindle 1, the latter transmitting the drive to the valve member via a disc 8 and a spring 7 which additionally functions to bias the valve member towards its seating. The valve member may have an aperture therethrough to co-operate with one or other of the inlets at respective end-of-rotation positions of the valve member. The ridge 11 may be replaced by two pointed projections or by one or more hinges. A pressure regulator may be provided in housing 4 to keep the two gas flows to the inlets at the same pressure.
