Production of laminar articles

Abstract: A process in which a skin material is injected through a sprue channel into a mould cavity followed by a core material, wherein a further quantity of skin and/or core material is injected into the mould cavity through a second sprue channel displaced from the first.

Nephrotoxicity of 4-aminophenol glutathione conjugate.

Abstract: 4-Aminophenol (p-aminophenol, PAP) causes selective necrosis to the pars recta of the proximal tubule in Fischer 344 rats. The basis for this selective toxicity is not known, but PAP can undergo oxidation in a variety of systems to form the 4-aminophenoxy free radical. Oxidation or disproportionation of this radical will form 1,4-benzoquinoneimine which can covalently bind to tissue macromolecules. Recent studies have shown that certain benzoquinol-glutathione conjugates can cause renal necrosis in rats. We have synthesized a putative glutathione conjugate of PAP. The effect on the kidney of this conjugate and the sulphate and N-acetyl conjugates, known metabolites of PAP, have been examined in Fischer 344 rats. 4-Amino-3-S-glutathionylphenol produced a dose-dependent (92-920 μmol kg-1) necrosis of the proximal tubular epithelium and altered renal excretory function. The lesion at the low dose was restricted to the pars recta of the proximal tubule in the medullary rays, while at the higher doses it affec...

A New Herbicide: 1 : 1′-Ethylene-2 : 2′-Dipyridylium Dibromide

Abstract: Low-volume applications of this herbicide (developed by I.C.I.) at 2-5 lb./acre, gave good top-kill of various brush species, including Rubus spp., Rosa spp., monogyna, Sambucus nigra and Ulmus spp. In all cases, however, there was basal regeneration.

Pattern printing apparatus

Abstract: An improved droplet printing apparatus of the type wherein a succession of ink droplets directed at regular intervals along the same flight path may be individually charged to one of a plurality of charge levels by application of a voltage waveform of constant period to groups of drops. Each charged drop is deflected from the common flight path by passage through an electric field, to an extent dependent on the charge carried so that during relative motion between the apparatus and a surface to be printed ink drops may be deposited on the surface in successive rows extending transversely to the direction of relative motion; all ink drops not being required for deposition being directed into a drop intercepting means. The improvement comprises the provision of means for introducing a delay between adjacent voltage waveforms and means for directing all drops formed during such delay into the drop intercepting means.
