Abstract: When polyphosphazenes are exposed to elevated temperatures, their physical properties often deteriorate. The addition of a stabilizing compound represented by the structure:
     wherein W is -CRR'-CRR' or
     ; and wherein R and R' are selected from the group consisting of hydrogen, alkyl, cycloalkyl, acyl or a mixture thereof, and M is zinc or magnesium; to pbtyphosphazene rubbers result in improved retention of the physical properties of such polyphosphazenes. Further, the use of additives of this type does not adversely affect the ability of peroxy compounds to cure the polyphosphazenes to form vulcanizates. 
     Especially useful compounds represented by the above structural formula are zinc or magnesium 1,2-bis (2- oxybenzylideneamino) ethylene.

Abstract: It has been found that devices for determining nuclear spin density distributions in an object by means of nuclear spin resonance measurements produce artefacts in the calculated density distributions. The artefacts occurring are dependent of the gradient magnetic fields which are used during the measurements and which influence the excited nuclear spin. The invention concerns two filters for elimination of the artefacts in dependence of the kind of modulation of the gradient magnetic field.

Abstract: A high purity chemical synthesis gas is produced by reacting steam in a gasifier (32) with a carbonaceous feed material in the presence of a carbon-alkali metal catalyst and substantially equilibrium quantities of added hydrogen and carbon monoxide, fed in via nozzles (35), at reaction conditions to produce a raw product gas. The raw product gas is treated in vessels (38), (41) to remove solid particles, and in vessels (51, 54, 59 and 63) for the removal of steam and acid gases. The thus purified gas contains, primarily, carbon monoxide, hydrogen and methane. Methane is removed in a heat transfer unit (67) and a cryogenic unit (71), thereby recovering carbon monoxide and hydrogen from the treated gas as a chemical synthesis product gas. The remaining mixture of steam and methane is passed with further steam into a steam reforming furnace (76) where the methane reacts with the steam to produce carbon monoxide and hydrogen. The effluent from the reforming furnace (76) is passed into the gasifier (32).
