Title: Improvements in high gain antenna system with low side lobes
IPC: H01Q11/06
Filed: 1965-03-26
Abstract: 1,108,092. Aerials. SANDERS ASSOCIATES Inc., 26 March, 1965 [26 March, 1964], No. 12855/65. Heading H4A. An aerial array comprises at least two spacedapart, overlapping V-aerials 118, 120, Fig. 12, the legs 126, 128 of the one being parallel, respectively, with the legs 130, 132 of the other, and the bisectors of their apex angles being co-planar, said aerials being fed at their apex 122, 124 from an R.F. source with a phase difference between them determined by their spacing S H  so that their radiations combine in a direction lying in the plane of the said bisectors. As described, the apexes 122, 124 of the aerials are higher above the ground than their ends 126a, 128a, and 130a, 142a and the latter are terminated by resistors 134. The spacings S H  and S v  between the aerials are arranged so that sides lobes produced by the array are minimized and radiation is concentrated in the main lobe. In a second embodiment (Figs. 4, 5, not shown) aerials of tandem-V form are used, in which each V-aerial is connected at its ends to the ends of a second opposite-facing V-aerial. The second V-aerial may be of the same shape as the first V-aerial and be co-planar with it, when a rhombic aerial is formed. As described, an aerial (10) is supported by masts (62) at its apexes and transverse corners and another similar aerial (12) is supported below at a distance Sy by other masts (62), the horizontal separation of the aerials being S H . In a third embodiment, (Figs. 10 and 11, not shown), two tandem-V-aerials (84), (86) are supported on six masts only, common apex masts (108), (110) being used, and in a fourth embodiment (Figs. 14, 15, not shown) two arrays of this kind are combined using a total of eight masts. The terminating resistances may be omitted from the aerials, although they will then usually cease to be uni-directional. The reflectivity of the ground may be enhanced if necessary by installing ground wires. Multiples of the arrays may be used to improve directivity. An array with a feed arrangement such that both horizontally and vertically polarized waves are radiated is described (Fig. 13, not shown) and comprises a transformer (138) having a primary winding (140) and a secondary winding (142) provided with a centre tap 144. The secondary (142) is connected to the aerial and a transmitter (150) for horizontally polarized radiation to the primary (140). A transmitter (154) for vertically polarized radiation is connected to the secondary centre tap (144).

Title: Process for the recovery of carbon dioxide of very high purity
IPC: C01B32/50
Filed: 1961-04-14
Abstract: <PICT:0951548/C1/1> Carbon dioxide is recovered from a gas containing CO2 by countercurrently scrubbing the gas with a liquid capable of absorbing carbon dioxide at 5-100 Atm., reducing the pressure of the liquid in a turbine to 20-80% of the scrubber pressure and separating the gas, containing the greater part of non-CO2 gas, in a separator; the liquid is then passed to one or more vessels in which the pressure is reduced to 0.3-3.0 Atm. below the pressure in the separator and each preceding vessel, the gas is separated and the liquid passed to a second turbine at a pressure 0.2-2 Atm. higher than the static pressure of the column of liquid between the second turbine and the gas collector in which pure CO2 is separated from the liquid passing from the second turbine and which is located above this turbine. The scrubbing liquid may be water, an aqueous alkaline solution, or an anhydrous liquid absorbent e.g. an aqueous solution of ammonia or an organic derivative or of an alkali metal salt of a weak acid. Gas containing CO2, CO, H2, N2, A and CH4 at 28 Atm. is mixed with gas from separator 3 containing CO2, CO and H2 which is compressed by 4. The mixed gas containing 29% CO2 is fed to scrubber containing H2O at 28 Atm. and is treated to leave 0.3% CO2. Scrubbing H2O from 1 is passed to turbine 2 at 8.9 Atm. yielding gas to 3.  H2O from 3 is passed to vessel 5 at 7 Atm. yielding a gas containing CO2, CO and H2 which is vented to atmosphere. H2O from 5 is fed to turbine 6 at a pressure of the water column from 6 to degasifier 7 where 99.2% pure CO2 is obtained. H2O from > is freed from dissolved gases in 8 by aeration and then returned to 1 via pump 9 driven by motor 10 supplementing turbines 2 and 6.

Patent GB-772716-A (GB)
Title: Improvements relating to electrical code systems
Inventor: HUNTLEY KEITH GORDON
IPC: H03M1/00
Filed: 1953-05-16
Abstract: 772,716. Pulse code modulation circuits. ELECTRIC & MUSICAL INDUSTRIES, Ltd. May 7, 1954 [May 11, 1953], No. 13784/53. Class 40(5) In a binary digital coder or decoder, two normally closed gates are provided for applying respectively to a signal accumulator two exponentially decreasing signals of opposite sign. In the coder, the analogue signal to be coded is compared at successive instants, between which the exponential signals decrease by one half, with the accumulated signal, one or other of the gates being opened depending on the sign of the comparison, and the digit signals are derived from the gate operations. In the decoder the gates are controlled by the incoming digit signals and the analogue value is derived from the signal accumulator at the end of a code group. Depending upon the position of the switch S5. the circuit described may act as a coder or decoder. At the beginning of a coding period, gates G1, G2, are rendered non-conducting by a negative potential from terminal T7, so that the time-constant circuit C1, R1, across the see-saw amplifier A, which has previously been charged to a potential Eo through resistances R21, R22, begins to discharge. At the same time, the integrating condenser C2 across amplifier C, forming the signal accumulator, has a shortcircuit removed by rendering gate G7 non- conducting. The exponentially decreasing potential at the output X of the amplifier A is fed to a see-saw amplifier R31, R32, B so that the output Y is the inverse of the input X, the points XY being connected through resistors R41, R42 and gates G3, G4, respectively, to the condenser C2. Gates G3, G4 are controlled so that one or other is open, depending on the condition of a two-state circuit F. This condition depends on the sign of the input to amplifier D which is derived from the algebraic difference of the integrated potential at terminal Z of condenser C2 and the analogue potential to be coded on terminal T8. The output of amplifier D is fed through switch S5 to the gates G5, G6, of which the former conducts with a negative control voltage and the latter with a positive conrol voltage, so that clock pulses from terminal T6 pass to the correct input to device F to set gates G3, G4 correctly. The pulses passing gate G5 are fed to the code output terminal T9 through switch S5. When used as a decoder, with switch S5 in the other position, incoming code pulse groups are fed to terminal T9 and thence control the gates G5, G6 so that condenser C2 builds up the corresponding analogue potential. This is amplified by amplifier D, now arranged as a see-saw circuit and feeding the terminal T8 acting now as the decoder output point. In a modification of the coder the signal accumulator may initially have stored therein the negative of the potential to be encoded the comparisons then being between the resultant :accumulator potentials and zero. Specification 772,714 is referred to.
