Title: Improvements in or relating to object detecting and locating systems employing electromagnetic waves
IPC: G01S13/50
Filed: 1943-12-17
Abstract: 616,966. Measuring phase differences. LELAND STANFORD JUNIOR UNIVERSITY, BOARD OF TRUSTEES OF. Dec. 17, 1943, No. 21252. Convention date, Sept. 30, 1941. [Class 37] [Also in Group XL (c)] A radiolocation system (see Group XL (c) utilizes the Doppler effect to obtain the distance of a moving target by transmitting two or more ultra-high-frequencies and comparing the phases of the Doppler beat notes produced in the different frequencies. For each transmitted frequency, the frequency of the beat note produced by mixing the transmitted frequency with the corresponding reflected frequency changes by unity as the target moves through a distance of a half wavelength relative to the transmitter. This corresponds to a phase difference of 360 degrees and thus the phase of the beat note is a function of the distance. If, for example, two frequencies of wavelengths 9 cms. and 9.000027 cms. are transmitted, in a return distance of 30,000 metres (corresponding to a target range of 15,000 metres), there will be one more of the shorter waves than of the longer ones so that the phase difference of the beat notes will be 360 degrees for this distance and the actual phase difference measured for any target within this range will give the target distance as a fraction of 15,000 metres. The two wavelengths mentioned correspond to a frequency difference of 10,000 cycles per sec. and if a third frequency differing from one of the others by 100,000 cycles per sec. is also transmitted, the phase difference measured will give the partial distance as a fraction of one of the 1500-metre components of the 15,000-metre range. Thus, by utilizing the three frequencies, a coarse and fine reading of the distance is obtained. The coarse and fine readings may be obtained by intermittently varying the frequency of one transmitter and synchronously connecting up two phase comparators by a commutator, Fig. 18 (not shown). Fig. 4 shows a cathode-ray tube employed as a phase indicator. When two ultra-high-frequencies are used, one of the derived Doppler beat frequencies is applied from amplifier 22 to the vertical and horizontal deflecting plates in quadrature to produce a circular trace. The second Doppler beat frequency from amplifier 23 is connected through a saturated transformer 56 producing an impulse in the secondary circuit each time the current in the primary passes through zero. These impulses are applied to the cathode 45 and produce oppositely-directed cusps 41<1>, 41<11> in the circular trace, Fig. 15, the position of these cusps indicating the phase difference between the two beat frequencies. Alternatively, the second beat frequency may be applied over transformer 561 to the control grid 42 to produce a bright spot 41a and a faint spot 41b in the circular trace. When three frequencies are transmitted simultaneously, all three inputs 102, 103, 1031 are used and the two kinds of indication provide the coarse and fine readings.

Filed: 1932-07-29
Abstract: <PICT:0398992/III/1> Highly - viscous mineral lubricating-oils are purified by liquid sulphur dioxide in a counter-current mixer by first reducing the viscosity of the oil by mixture with about 10-40 per cent of sulphur dioxide.  The diluting dioxide may be introduced as liquid or as gas under pressure.  Mixtures of sulphur dioxide with, for example, benzene or low-boiling extract may be used for the extraction and dilution.  For example, a pump 5 supplies lubricating oil from a tank 1 to the mixer 10 through pipes 2, 6, a heat exchanger 8, and a pipe 9, while sulphur dioxide is supplied through pipes 11 and 3.  The extract passes through a pipe 12 to the evaporators, the raffinate through a pipe 14, a pump 15, a pipe 16, the heat exchanger 8, and a pipe 17 to the evaporators. Specification 258,846, [Class 91, Oils &c.], and repeated treatment with liquid sulphur dioxide, are referred to.

Abstract: 1430253 Bending pipes CRC-CROSE INTERNATIONAL Inc 5 April 1973 [6 June 1972] 21685/75 Divided out of 1430251 Heading B3E A mandrel for supporting the wall of a pipe during bending, e.g. bending cross-country pipeline section by the method of the parent Specification 1,420,251 on the apparatus of codivisional Specification 1,430,252, comprises two elongated pipe-engaging assemblies side-byside, one assembly including at least one elongated inflatable bag, and means for forcing the two assemblies apart. In the embodiment described, Fig. 15, both assemblies are flexible, and the lower, 121 is hung from the upper, 120, which also supports wheels 125<SP>1</SP> on arms 124 such that the wheels contact the pipe wall floor when assembly 121 is raised. Alternatively, the wheels may be on adjustable arms. The wheels may be driven by a diesel or hydraulic motor. The upper assembly, see also Figs. 16 and 17, consists of end plates 122, 123 connected by longitudinal spring steel strips 125, 126. These are joined by seven curved spring steel sheets 127 with attached ribs 128 and supporting rods 129 which pass freely through the ribs. Longitudinal spring steel strips 130 are laid on sheets 127 and attached to the end plates. Polyurethane segments 132 are laid on strips 130, and accommodate hydraulic bags 135, spring steel tie-bars 132, and triangular filler springs 133. Spring steel strips 136 are let into the pipefacing surfaces of the segments 132. The bags are hydraulically interconnected in sets, so that for example those at the top of the assembly may be inflated at a higher pressure than those at the sides. The lower assembly comprises seven transverse members 144 connected by longitudinal spring steel strips 147 to which are bolted resilient pipe-contacting blocks 148. Each member 144 is confronted by a transverse member 140 on the upper assembly, and these members have opposed cam faces 142 and shoulders 143. Two bars 149 with bosses 150 are located between each opposed pair of members, so that when moved sideways by jacks 152 and headers 153, the bosses 150 move over the cam faces 142, so moving the assemblies apart, and finally oppose the shoulders 143, locking the assemblies apart. The bars 149 are guided by arms 151 which may be interconnected to ensure equality of movement of a pair of bars. When installing the mandrel, inflation of the bags and forcing apart of the assemblies may take place in either order. Smaller subsidiary mandrels may be used to support the pipe walls at locations spaced from the main mandrel, being constructed with a single curved sheet 127 and one set of members 140, 144 and one pair of bars 149 operated by two jacks. These mandrels may be attached to the main mandrel, or separate.
