Abstract: 1,165,170. Analogue/digital converters. FUJITSU Ltd. 16 Dec., 1966 [16 Dec., 1965], No. 56555/66. Heading G4H. In an analogue/digital converter of the type in which the input analogue signal is sequentially compared with feedback reference signals to give difference signals, the polarities of which represent the digital output bits, after m-bits have been generated the difference signal at the mth-bit is amplified and compared with the reference signals to generate the remaining bits. In one embodiment a holding circuit 402 (Fig. 4) stores the output signal and feeds it via a switch 4082 (closed for bit times 1-3) in a gate 408 to a summing node 403 where it is combined with an initially zero reference signal generated by circuitry 406 and the polarity of this signal determined in a detector 405 which controls circuitry 406 and delivers the binary coded output bits to terminal 409. After three bits the difference signal, amplified by four and stored in holding circuit 407, is fed via switch 4081 (closed for bit times 4-6) to the summing node 403. Three more bits are then generated, the third and fourth bits of the resultant six-bit signal overlapping. In a modification (Fig. 8, not shown) in which a six bit signal is generated, after three bits the amplified difference is rectified and a bias voltage added to it before it is stored in the holding circuit. If the third bit is zero the remaining three bits are inverted by a code converter (804) before being fed to the output terminal (409).

Abstract: 1,198,859. Fuel cell operation. GENERAL ELECTRIC CO. 27 Dec., 1967 [30 Dec., 1966], No. 58702/67. Heading H1B. Electricity is generated by electrochemically oxidizing a monohydric alcohol containing less than 4 carbon atoms at a porous anode, electrochemically reducing an oxidant at a porous cathode separated from the anode by an electrolyte and connecting a load between the electrodes, the rate of supply of the reactants being such that, were the electrodes short-circuited the limiting current could be varied by varying the rate of supply of the alcohol and the actual current being less than this limiting current. The actual current is preferably at least 85% of the limiting current producing incipient alcohol starvation at the anode. Any excess alcohol at the anode is delivered to the cathode where it is consumed. In a particular embodiment, Fig. 2, a fuel cell comprises electrolyte matrix 114 situated between anode 110 and cathode 112. Fuel reservoir 108 is bounded by gas-permeable, liquid impermeable plug 104 and liquid permeable plug 106.
