Title: Method of producing ammonia
Inventor: MATROS JURY SHAEVICH
IPC: B01J8/04
Filed: 1987-09-23
Abstract: A method of producing ammonia provides for introducing a nitrogen-hydrogen mixture into a catalyst layer divided into at least two parts by a plane which is perpendicular to the initial gas mixture flow direction. The temperature of the initial gas mixture introduced is 20-250 DEG C, its pressure 10-100 MPa and the temperature of the catalyst before introduction of the inital gas mixture is 420-590 DEG C. The direction of the initial gas mixture introduced into the catalyst is periodically changed to the opposite one. The nitrogen-hydrogen mixture is mixed between the catalyst layers formed during the division of the latter in a ratio of (0.5-1):1 until its temperature gradient between the preceding and subsequent layers of the catalyst does not exceed 20 DEG C. The ammonia generated and the non-reacted part of the nitrogen-hydrogen mixture are extracted from the catalyst layer. The method of producing ammonia enables an end product with a yield of 14-30 % to be obtained.

Title: Optical radiation demodulator circuit
Inventor: HOLFORD KENNETH
IPC: H04B10/69
Filed: 1988-09-12
Abstract: A demodulator circuit (8) for amplitude-modulated optical radiation incident on a photodiode (1) is given a bandpass frequency characteristic by virtue of the fact that an inductance (4A,4B) is effectively connected across the photodiode so that it forms a parallel resonant circuit with the internal capacitance of the diode. In order that the characteristic should not be too narrow it is arranged that the photodiode capacitance constitutes substantially the whole of the capacitive element of the resonant circuit and that the resonant circuit is damped by the input impedance of a shunt feedback amplifier (9,17,18,20,21) which is employed as a preamplifier for the signal voltage set up across the resonant circuit. <IMAGE>

Patent GB-2238796-A (GB)
Title: Sintering of permanent-magnet bodies of rare-earth alloys
Inventor: BAYLEY HOWARD KENNETH
IPC: C22C1/04
Filed: 1989-12-06
Abstract: A permanent-magnet body is formed by sintering together grains of an alloy comprising at least one 3d transition element and at least one element selected from the rare-earth metal group (inclusive of yttrium). The size of the alloy grains (e.g. less than 0.3 mu m) and the sintering temperature are in a range which provides a desired coercivity Hcj. In accordance with the present invention before sintering, there is mixed together with the alloy grains a grain-growth inhibitor (e.g. granular alumina of less than 0.1 mu m) which is of a sufficiently small size and is sufficiently chemically inert in relation to the alloy at the sintering temperature as to form a physical barrier inhibiting inter-grain growth at the grain boundaries of the alloy during sintering. This enables the desired coercivity to be obtained over a wider temperature range for the sintering process. This is particularly useful for single-phase alloys of the RCO5 type (where R is at least one element selected from the group Sm, Y, Ce, Pr and Nd). Thus, for SmCo5, the sintering may be effected at a temperature in the range of 1125 DEG C to 1150 DEG C to provide a coercivity Hcj in excess of 1600 kA.m<-1>.
