The first twenty years of microwave radar development was done entirely without the benefit of ferrite devices. The first experimental microwave ferrite device was demonstrated in 1949. Ten more years of research and development on the devices was required before significant performance was achieved and large scale co…

The authors performed 169 Tm Mossbauer spectroscopy on the cubic Laves-phase compounds TmNi 2 , TmRh 2 and TmIr 2 in the temperature range 2-300K and found well resolved quadrupolar splitting at low temperature. In cubic compounds this feature is uncommon and they explain it as indicating the presence of a static or d…
Abstract The effect of absorbed doses of ionizing radiation up to 2MGy in the presence of air on the melting behavior of high‐ and low‐density polyethylene was analyzed from data obtained by differential scanning calorimetry. Thermal measurements were made during the first melting after irradiation. The first melting…

Abstract The studies described in this papier lead to certain conclusions. The crosslinking reaction of halobutyl with zinc oxide does not give rise to ether crosslinks. All the evidence indicates that the chemistry involves the formation of carbon-carbon bonds by an alkylation type chemistry. The dehydrohalogenation…
Line pipe steels with excellent resistance to wet sour gas are urgently needed because of increased use of sour gas reserves that have a higher hydrogen sulfide concentration, and because of higher operating pressures. The authors conducted extensive analyses to explore the effects of metallurgical factors on the resi…
Abstract The powder diffractograms of twenty wet chemically analysed samples in the isomorphous triphylite-lithiophilite series and five synthesized members with Fe/(Fe + Mn) = 1, 0.75, 0.50, 0.25, and 0.0, were recorded. Their unit cell dimensions were accurately refined in order to find a reliable method for semi-qu…
The photoelectrochemical properties of were studied in aqueous electrolytes. The onset potential of the anodic photocurrent in steady state was found to be about 1V more anodic than that of the photocurrent measured by the lock‐in method (−2V vs. SCE). This discrepancy was ascribed to the presence of transient photocu…
Organic photochromic compounds await major commercial exploitation. The main characteristics of these materials are outlined and their applications are discussed. These include: optical data recording, optical data processing, optical waveguide components, inks for security applications, displays, variable density fil…
The domain wall stabilization caused by anisotropy induced during annealing has been studied in amorphous ribbons. It was found from domain observation that the regions where there existed domain walls during annealing tend to become nuclei of reverse domains as well as pinning sites of domain walls. The increased wal…
In the study of transient or steady-state eddy current effects, a general diffusion equation derived from Maxwell's equations is solved by a classical finite element method for the spatial problem with time discretization. The moving part of the system is taken into account by a mesh distortion where the mesh points a…
The phase diagram of the system U‐Mo‐O in the region UO 2 ‐MoO 2 ‐O was investigated by X‐ray phase analysis and electromotive force measurements. The isothermal section at 1000 K is presented. The free energy of formation of UMoO 5 was determined from the oxygen potential measurement by a ZrO 2 .CaO solid electrolyte…
Abstract A simple method for the synthesis of α,ω‐bis(vinylbenzyl) aromatic poly(ether‐sulfone)s ( 2 ) and their transformation into α,ω‐bis(ethynylbenzyl) aromatic poly(ether‐sulfone)s ( 4 ) is presented. This method involves a fast and quantitative Williamson etherification of the α,ω‐bis(hydroxyphenyl)polysulfone w…
A brief survey of the status of work in the higher induction and frequency ranges is given and recent papers on the measurement of rotational losses are reviewed. The determination of the magnetic losses in alternating fields is considered, in partucular regarding the performance of those magnetic circuits most widely…

Abstract A comparative study of α- and γ-functiona1 sulfur-containing silane coupling agents in the silica-filled SBR cured by the conventional sulfur system showed that the influence of the silanes on the vulcanization kinetics and their coupling effectiveness depends on the structure and positioning of the rubber-re…
