Title: Production of high pressure hydrogen-rich gas particularly for ammonia synthesis
IPC: C01B3/52
Filed: 1967-01-11
Abstract: 1,137,371. Hydrogen; ammonia. PULLMAN Inc. 11 Jan., 1967 [19 Jan., 1966], No. 1614/67. Heading C1A. [Also in Division C5] A hydrogen-rich gas at intermediate pressure made by a catalytic steam re-forming and/or a partial combustion process, or by the carbon monoxide shift conversion process, is compressed to a high pressure, e.g. 2200 p.s.i.g. at least in part by the energy provided by expanding steam which was generated at a pressure, (e.g. 1450 p.s.i.g.) greater than the intermediate pressure. Nitrogen may be present in the hydrogen-rich gas at intermediate pressure. The mixture at high pressure may then be catalytically converted to an ammonia-containing gas. Boiler feed water at 1500 p.s.i.g. enters at 161 having traversed heat exchangers 74, 78, 84, 124, its path to compressor 91 being via 14, 19, drum 162 (which receives steam at 1500 p.s.i.g. from the exchangers 31, 32, 37 in parallel) 173 and 19, to a steam turbine (229), see Fig. 2 (not shown), driving the compressor 91. Make gas leaving the secondary reformer 23 traverses the apparatus 34, 35, 53 and 82 to the first stage 92 of the compressor 91, part being recycled at 800 p.s.i.g. via 12 to the hydrocarbon feed input. and the rest entering the ammonia synthesis apparatus (illustrated in the bottom L.H. quarter of the Figure) which includes a further compression stage 93. Steam leaving the turbine (229) is divided, one part driving a second turbine (234) for the compressor, and the rest providing steam at 540 p.s.i.g. for driving sundry pumps and compressors, and for delivery at 17, 27 to the reformers. Condensate is recycled to the boiler feed water input. Hydrocarbon feeds include refinery gas, coke oven gas, natural gas, 1.p.g. naphthas, crude and residual oils, and solids.

Title: Improvements in measuring apparatus employing beta rays
Inventor: WILLS GRAHAM BOYCE

Filed: 1958-01-20
Abstract: 846,416. Nuclear radiation testing arrangements. BRITISH INSULATED CALLENDER'S CABLES Ltd. Jan. 19, 1959 [Jan. 20, 1958 March 6, 1958], Nos. 1927/58, 1928/58 and 7249/58. Drawings to Specification. Class 40(3). The invention is concerned with improving the sensitivity of measuring apparatus of the kind in which a stream of electrons from a suitable source is directed on to a composite material under examination and a detector feeding an indicator is arranged to detect electrons backscattered from the material. The apparatus may measure the thickness of a coating of one material on another or the proportional content of two materials in a mixture, dispersion, alloy, or compound. The sensitivity of such apparatus varies with the difference between the atomic numbers of the two materials under consideration. According to the invention the sensitivity is improved by limiting that part of the response of the indicating device which represents the back-scatter flux of #-particles to one to only those electrons with energy above a predetermined level. The level is chosen to give a socalled magnification factor (M) of at least two where:-  In this equation N A  and N B  represent the maximum theoretical back-scatter flux from the saturation back-scatter thickness of materials A and B respectively and N<SP>1</SP>A and N<SP>1</SP>B represent the part of this flux allowed to affect the indicating device. One way of limiting the response is to place a filter in front of the detector. The filter is preferably a sheet of metal of low atomic number such as aluminium. This can either replace the window of the detector or be separate from and external to it. The latter arrangement is preferred as interchangeable filters of differing thickness can then be used. It is preferred to use a filter such that its arcal density (together with that of the detector window if significant) is from 10 to 40% of the penetration thickness for the radiation incident on the material under test. Another way of limiting the response which can be used instead of, or in addition to, the one above is to pass the output of the detector through a discriminator circuit. Or again, the detector itself may be reduced in effectiveness. For example if the detector is a scintillation counter comprising a phosphor and a photo-multiplier tube the applied voltage may be reduced. Where a discriminator circuit is used the response level may be set by control of the amplification of the circuit, by use of a gate valve, or by biasing the input of a trigger circuit following the amplifier circuit and operating to integrate the pulse signals fed from the detector. Integration can conveniently be effected by use of capacitor charging arrangement. Calibration of the indicator is done by noting the readings given by pure samples of sufficient thickness of each of the materials under consideration and for samples of coatings (or mixtures &c.) of known thickness (or composition).

In a system for measuring at a station A the distance of a station B each station includes a coherent carrier wave generator 11 frequency modulated at a frequency which is slightly different for the two stations, a mixer 15, an intermediate-frequency amplifier 16, an amplitude limiter 17 and a frequency modulation detector 18, the carrier wave at B is additionally modulated by the output (possibly coded) of an amplitude modulation detector 19 and the phase of the output of detector 18 at A is compared with that of an amplitude modulation detector 19 to give the distance AB. The carrier frequencies at A and B differ by the intermediate frequency. According to the invention the bandwidths of amplifiers 16 are at least sufficient to pass first-order frequency modulation sidebands. This is stated to allow for sudden changes in velocity of wave propagation, for signal distortion, for ground reflexions and for carrier instability. The carrier frequencies may correspond to microwaves.

Abstract: 576,741. Refrigerating. DEHN, F. B. (Mills Industries, Inc.). Feb. 4, 1944, No. 2091. [Class 29] The desired proportion of air whipped into ice cream is maintained automatically in the ice cream maker itself by controlling the temperature of the refrigerant contained between the ice cream barrel 6 and the outer barrel 4. When the ice cream has been made and whipped in the barrel 6 the valve 10 is closed, whereupon any rise in temperature in the barrel causes a corresponding rise in pressure in the vapour 17 which closes a pressure switch 12 to complete an electric circuit 18, 19 to open a solenoidoperated valve 13. This opens the suction communication through a bypass 8, 11 to the compressor and condenser 1 to begin and continue refrigeration to decrease the temperature until switch 12 opens to stop refrigeration. A constriction 15 reduces the rate of flow of the vapour back to the compressor to prevent excessive short-cycling. A thermal bulb 5 located to receive the combined temperature of the ice cream barrel and the refrigerant vapour 17 controls a thermostatic expansion valve 3 to regulate the amount of refrigeration to freeze the barrel contents at the desired rate.
