Patent GB-2031613-A (GB)
Title: Production of chlorine dioxide
IPC: C01B11/02
Filed: 1979-08-28
Abstract: An automatic continuous monitoring system for a chlorine dioxide generating process (10) which produces a gaseous mixture of chlorine dioxide and chlorine (12) is described. The automatic system eliminates the need for periodic manual analysis of the off-gas stream and enables changes in the process efficiency to be rapidly compensated for. The efficiency is an indication of the rate at which the desired reaction is proceeding in the face of competing reactions. The system preferably utilizes a gas-liquid chromatograph analyser (36) to analyse off-gases from the generator (10) and to provide signals (43, 44) corresponding to the measured amounts of chlorine dioxide and chlorine. These signals then are converted (46) to a signal (47) corresponding to the ratio of chlorine dioxide and chlorine in the off-gas stream. The ratio is then converted to the efficiency (48). The efficiency value so obtained (49) may be compared with a previously determined value and changes compensated for by catalyst and/or reactant feed variations. The gas analysis may be used in combination with actual production rate and required production rate determinations, possibly along with reaction medium analysis, in a machine controlled chlorine dioxide- producing process in which programmed integrated circuits are used to effect calculations and adjustments. <IMAGE>

Patent GB-2064082-A (GB)
Title: Improvements in or relating to cryogenic liquid transfer systems
IPC: F17C9/00
Filed: 1980-08-15
Abstract: When transferring cryogenic liquids at low flow rates the fluid effusing from the transfer pipe can have an unacceptably low liquid fraction. Usually a pre-cool of the transfer system is employed, however, this is time consuming and wastes liquid cryogen. Above a critical wall temperature the heat flux is sufficient to produce a Leidenfrost flow which substantially insulates the liquid from the wall or the transfer pipe. In the invention a transfer pipe (1) with a cryogenic liquid flowing within it is a heated by a flow of warm gas (4) passing over it. The temperature of the gas is maintained by a heating coil (3) and the gas is contained within an envelope (5). The principal application of the invention is in the supply of liquid cryogen to and through a surgical cryoprobe which may also contain an endoscope. <IMAGE>

Patent GB-808510-A (GB)
Abstract: 808,510. Valve circuits for radio reception. GENERAL ELECTRIC CO. Feb. 13, 1956 [Feb. 14, 1955], No. 4436/56. Classes 40 (5) and 40 (6). The selectivity of a crystal filter is varied in accordance with the signal level by utilization of grid current in the succeeding valve. Signals are fed to an amplifier 10, the anode circuit of which comprises inductance 14, which may be variable and variable condenser 18 in series with inductance 20. Inductance 20 feeds the crystal 22 and is of low inductance relative to inductance 14, the elements 14, 18, 20 forming an impedance matching network. The crystal is neutralized by means of condenser 34 and inductance 32 which is bifilar wound with inductance 20. The crystal feeds into valve 40 via a seriestuned circuit comprising resistor 52, inductance 36 and condenser 42. The selectivity of the circuit is high for small signal levels and is brought to a desired value by means of resistor 52, but at higher levels the valve 40 runs into grid current, reducing the selectivity; the degree of reduction is determined by the value of the grid leak 44, which may alternatively be positioned at 44<1>. The arrangement is primarily intended for deriving the reference wave in a colour television receiver, for which purpose a higher selectivity is desirable when receiving weak signals.
