Recent Patents

Somewhat unanticipated applications can arise. For example, a process for the production of ultrapure hydrogen peroxide for the electronics industry has been patented recently,1425 which uses the macrobicyclic hexamine complex (29) supported on an inert material for dioxygen... 

Symmetrical premetallised 1 2 metal-dye complexes of unsulphonated monoazo structures with aluminium (5.57) or trivalent iron (5.58) have been patented recently for use as solvent dyes [36]. They contain a polar methoxypropylaminosulphone grouping in each diazo component and are marketed as alkylamine salts. It remains to be seen, however, whether a full colour gamut of bright aluminium and iron complex dyes can be discovered with light fastness performance equivalent to that of currently available chromium and cobalt complex dyes. 

A highly substantive bluish red bis(sulphatoethylsulphone) structure (7.73) has been patented recently [29]. In a kinetic study using the t.l.c. double-scanning method, the condensation reactions between the bis(aminochlorotriazine) dye Cl Reactive Red 120 (7.48 X = Cl) and the two isomeric sulphatoethylsulphone anilines 7.38 and 7.39 to yield the two corresponding bis(sulphatoethylsulphone) isomeric dyes were compared. The rate constant of the reaction between Red 120 and the meta isomer 7.39 was about ten times as large as that for the para isomer 7.38 [64]. 

Aspartame is a high intensity dipeptide sweetener, ca. 200 times as sweet as sncrose. It was originally developed by G.D.Searle Co. prior to their acqnisition by Monsanto. Chemically synthesised aspartame has rapidly acqnired a major share of the world high intensity sweetener market, particnlarly in soft drinks. Until recently it has all been snpplied by a monopoly snpplier, the Nntrasweet Corp (a Monsanto-AJinomoto joint ventnre) protected by prodnct patents. Recently biocatalytic methods... 

Seeurite or Sekurit, A gelatinized O-ba-lanced safety explosive patented recently in Sweden by Wetterholm, It is described in this Vol of Encycl, p D1255 L... 

Several compds, some of them explosive, were patented recently by Swedish inventors. For their prepn, polynitro-alcohols(having all N02 groups attached to the same C atom and the OH group or groups attached to the adja-cent C atom) were treated with ammonia(or an N-substitution deriv thereof) in aq or other solns... 

A wide variety of new NOS inhibitors have been reported over the last couple of years, but clinical data have not been available up to now. A selection of NOS inhibitors patented recently is shown in the following scheme ... 

A generator for producing aerosols, smokes, fogs and layers of gas was patented recently in France(Ref 3)... 

Alkoxylated quaternary ammonium surfactants have been patented recently as performance boosters for detergent formulations [71 ]. 

There have been a number of patents recently that have given reasonable bleaches but none has been employed commercially. The useful peroxide bleaches control the silver electrode potential by complexing the silver [142] or by careful control of the halide concentration [143]. 

The full range of reactions for which these materials can be used has yet to be identified. There has been a flourish of new patents recently so it may not be long before scale-up results (at least to pilot plant) appear. Table 2 provides a list of seme of the laboratory-scale reactions so far reported.

The method utihzed for determining the axial and transverse components of the strain tensor in the above-specified RVE has been patented recently (26) as a novel option of the video-controlled materials testing system, VideoTraction , designed by two of the authors (C.G s. and J.M.H.) and licensed to the Apollor Co. (Vandoeuvre, France). We recall below briefly the main features of the method. 

Usefulness The invention has some definite, practical utility. The utility of the invention should not be merely hypothetical, abstract, or contrived. The rationale for this condition is self-explanatory the pubKc does not benefit from useless patents. Recently, the U.S. PTO raised the bar for proving the... 

Quaternary ammonium salts containing hydroxyl or ether functions in the shorter groups attached to the head-group are can also be used as hydrate inhibitors. Ethoxylated alkyldiamines are another class of cationic hydrate inhibitor that has been patented recently. In all of the above cases, cationic hydrate inhibitors appear to work best when used in combination with other additives. 

A patent recently was issued on strain AFPl 11 (18). This strain currently is designated ATCC 202021. 

Positive electrode materials in commercially available Li-ion batteries utilize a lithiated metal oxide as the active material. The first Li-ion products marketed by Sony used LiCo02. Goodenough and Mizushima developed this material, as described in a series of patents." Recently, cells have been developed that utilize less costly materials, such as LiMu204 (spinel), or materials with higher coulombic capacity, such as LiNii Co 02. Commercial interest in LiNi02 has waned as its instability, driven by the energetic formation of NiO and oxygen, has been shown to contribute to safety issues."... 

The combination of starch with a water soluble polymer such as polyvinyl alcohol (PVOH) and/or polyalkylene glycols has been widely considered since 1970 [150]. Recently, the system, thermoplastic starch/PVOH has been mainly studied for producing starch-based loose fillers as a substitute for expanded polystyrene [151-157]. As an example, Altieri and Lacourse developed a technology based on hydroxy propylated high amylose starch containing small amounts of PVOH for improving foam resiliency and density [151-155]. In this case loose fill was produced directly by a twin screw extruder. More recent patents. Recently more advanced processes and alloys have been developed which have resulted in foams with lower foam densities (8-6 kg/m3) and better performance [158-160].
