Abstract: An ammonia production process comprising synthesis gas generation and ammonia synthesis with heat recovery in the generation section by steam raising and steam superheating and heat recovery in the synthesis section by steam raising or boiler feed water heating is made more controllable by effecting part of the superheating in the synthesis section, so that a shut-down of the synthesis section results not only in a decrease in steam flowthrough the superheaters, but also in a decrease in the temperature of the steam fed to them. Thus overheating of the superheaters, a defect of some earlier processes, is avoided. 
     Referring to figure 1, the steam system that characterizes the process according to the invention is based, in this preferred flowsheet, on common steam drum 100. Drum 100 is fed with treated boiler water heated in exchanger 82 by reacted ammonia synthesis. 
     Water circulates from drum 100 through boilers 30, 36 and 40. Steam passing overhead from drum 100 is superheated in heat exchanger 80 by reacted ammonia synthesis gas at 32 and let down in high pressure pass-out turbine 104 driving process air compressor 108, which supplies hot air as a result of limited inter-stage cooling and feeds secondary reformer 28 at point 112 by way of preheater 110. 
     The process is operated with a synthesis pressure under 150, preferably 40-80 bar abs. and preferably synthesis gas generation is based on primary hydrocarbon steam reforming at such a pressure that synthesis gas compression is by under 50%.

In order, in such stockings, to make it possible in a simple way to make a perfectly fitting non-rolling edge and to produce a stitch pattern differing from a conventional stitch pattern, if desired a terry fabric formation, the stocking (1) is manufactured as a right/left fabric on a single-cylinder circular knitting machine with a dial and is equipped at least with one right/right-knitted end edge (7), whilst the right/right fabric can also be provided in further part regions of the stocking (1) adjacent to the end edge (7), with the exception of the heel (3), sole (9) and toe (4). For adaptation to particular anatomical conditions, the stocking (1) can be of a shape which has a differing diameter over the length and which is produced by changing the tension of the elastomeric weft yarn during the knitting of this. <IMAGE>

Abstract: The television signal is digitized by sampling it at an even multiple of its chroma subcarrier frequency, thereby to convert the television signal to a series of digital signals. The value of each digital signal is indicative of the value of the luminance component and the value of the amplitude and phase of the chroma component of each picture element. The phase of the chroma component of a reference picture element is changed by combining and averaging stored digital signals associated with selected picture elements whose chroma component is of the desired phase and which cancel out luminance components. A resultant luminance signal is generated by combining and averaging stored digital signals associated with selected picture elements so as to cancel out their chroma components, and the resultant luminance signal is combined with the phase- changed chroma signal to develop a final signal whose chroma component is of the desired phase.
