Title: Adaptive adjustment of RF amplifier load impedance to maximize efficiency
Inventor: GAYNOR MICHAEL
IPC: H03F1/02
Filed: 2009-12-08
Abstract: A variable impedance matching circuit 104 between the RF power amplifier 102 and the antenna 103 is adjusted to obtain a low DC current drain in the RF amplifier. The DC current drain may be sensed by a resistor 100, or, if the RF signal is pulsed, by a transformer. The arrangement avoids losses which would be present in conventional designs using two matching circuits, one matching the amplifier output to 50 Ohms and the other matching the antenna to 50 Ohms. A wide impedance matching bandwidth may be achieved. The variable impedance matching circuit 104 may use a variable capacitor or inductor, or a capacitor array switched by MEMS devices.

Patent GB-684039-A (GB)
Title: Phenol production
IPC: C07C37/08
Filed: 1950-04-24
Abstract: Phenols and aliphatic ketones are produced by the decomposition of a hydroperoxide or a dihydroperoxide by adding such a peroxide to a homogeneous reaction medium of acetone and concentrated sulphuric acid under substantially anhydrous conditions, the concentration of the sulphuric acid being between 0.05 and 10 per cent by weight.  The hydroperoxides for use according to the invention are prepared by the oxidation of alkyl substituted aromatic organic compounds of the general formula <FORM:0684039/IV (b)/1> where R1 and R2 are alkyl groups and Ar is aryl or alkaryl.  The oxidation is carried out in the liquid phase using air or molecular oxygen as the oxidizing agent either in the presence of aqueous alkali or preferably in the absence of an aqueous phase, but in presence of an organic peroxide or hydroperoxide.  Compounds mentioned which may be oxidized include p-cymene, cumene, di-isopropylbenzene, sec-butylbenzene, p-ethyl-isopropylbenzene and isopropylnaphthalene.  The decomposition of the peroxide may be undertaken either on the pure product or on the crude oxidation mixture.  It is preferred to purify the hydroperoxide by distillation under very low pressure. The reaction medium may include a proportion of the mixture of reaction products from a previous decomposition, or an amount of phenol may be added to serve as solvent.  It is essential to add the hydroperoxide slowly to the reaction medium to avoid a build-up and subsequent uncontrollable decomposition.  Examples of the process are given.  Specification 629,429 is referred to.

Patent GB-970725-A (GB)
Title: A comparison device for two decimal digits
IPC: G06F7/02
Filed: 1961-03-22
Abstract: 970, 725. Comparing digital data. OLYMPIA WERKE A. G. March 22, 1961 [May 6, 1960], No. 10437/61. Heading G4M. In an arrangement for comparing two binary coded decimal digits, a comparison stage is proyided for each binary place, each stage controlling the outputs of the lower order stages. An arrangement is described for comparing two decimal digits A, B represented in the binary excess-3 code, the digits A 1 -A 4  being registered in flip-flops FF 1 -FF 4  and the digits B 1 -B 4  in flip-flops FF 5 -FF 8 ; The flip-flops may comprise valves or transistors. As shown, A = 0101 and B = 0011, the conducting sides of the flip-flops being represented by shading. The complementary sides of the flip-flop pairs such as FF 1 , FF 5  are connected in pairs to "and" gates such as U 11 , U 12 , the gate U 11  being opened if A 1  = 1, B 1  = 0, and the gate U 12  being opened if A 1  = 0, B 1 -- 1. The gates U 11 , U 12 are connected to an "or" gate 0 1 , which provides an output if and only if the digits A 1,  B 1  are different, which output is inverted at I 1  to block further "and" gates such as U 23,  U 24  for the lower orders if A 1  = B 1 . The gates such as U 11 , U 12  are also connected to "or" gates O 5 , O 6 which produce "A > B" and "A < B" outputs when appropriate, these outputs being connected to a further "or" gate 0 7  and inverter L 4  which produces an "A = B" output when appropriate. The gates U 23 , U 24  &c. ensure that it is the digit of highest order which is used to represent the result of the comparison In order to compare two multi-digit decimal numbers, each binary coded decimal digit pair, commencing with the pair of lowest significance, is fed in turn to the circuit of Fig. 1, the outputs "A > B", "A < B" thereof being connected as shown to the inputs of the circuit of Fig. 2. Thus if an "A > B" input is applied to the flip-flop FFg, Fig. 2, it is changed over so that an "and" gate Use is opened to cause a flip-flop FF 11  to change over. A further "and" gate U 60  is then opened to produce an output "A > B<SP>1</SP>". The output of the circuit of Fig. 2 is always indicative of the last decimal place compared in the decimal numbers to be compared so that the final result of the comparison is indicated when all the decimal digits have been compared. Specification 970,726 is referred to.
