    Notes: Summary. A commercial machine for shelling peas was developed after numerous tests of methods for removing peas from pods. the pods are preheated in steam and then fed to a shelling section by means of a vibratory conveyor which aligns them for end-on presentation to a pair of rubber-covered rollers. A standardized feed gap between the conveyor and the rollers separates shelled peas from unshelled pods. Pods which fail to be gripped by the roller pass to a second slightly modified shelling section.Extensive tests showed that a greater yield of peas was obtained from the sheller operated on hand picked peas, than from conventional stationary or mobile viners operated on vines. Yield for the combination of a mechanical pea pod picker which would be necessary for commerical operations and the pea sheller was not determined. Peas from the sheller were virtually undamaged in contrast to vined peas and were consequently superior in flavour.Storage of pods for periods of several days before shelling led to an increase in pea maturity but quality was otherwise unaffected. Ability to store pods permits greater flexibility in harvesting and processing operations and allows an extension of the growing area serving a factory. In addition use of the pea sheller eliminates the need for most of the cleaning equipment as shelled peas are clean. Shelled peas pass directly to the processing line without any delay to cause deterioration.

    Description / Table of Contents: Zusammenfassung Impulskernresonanzspektroskopie wurde verwendet um die Anisotropie im Zustand des von faserigem Keratin absorbierten Wassers zu beobachten. Ausgerichtete Proben von Rhinozeroskeratin wurden für die Untersuching verwendet. Die Spin-Spin-Relaxationszeit zeigte eine geringe Abhängigkeit von der Orientierung der Faserrichtung in bezug auf das magnetische Feld. Dieser Effekt wird so gedeutet, daß die Rotationsfreiheit der abosorbierten Wassermoleküle im die zur Faserrichtung parallele Achse etwas größer ist als sonst. Die beobachtete Orientierungsabhängigkeit war zu klein um das Erkennen von irgendwelchen, durch Temperatur oder Absorptionsniveau bedingten, Tendezen zu ermöglichen.
    Notes: Summary Pulsed NMR was used to observe anisotropy in the state of water absorbed by the fibrous protein keratin. Aligned masses of Rhinoceros horn keratin were used for the study. The spin-spin relaxation time showed a slight dependence on the orientation of the fibre direction with respect to the magnetic field. This effect is interpreted as indicating a slightly greater rotational freedom of the absorbed water molecules about axes parallel to the fibre direction than otherwise. The observed orientation dependence was too small to enable any trends due to temperature of level of absorption to be detected.

    Description / Table of Contents: Zusammenfassung Die Zustände von absorbiertem Wasser in durch (i) Hydrolyse, (ii) Desaminierung, (iii) Zugabe von Ninhydrin, (iv) Zugabe von Dowfax modifizierten Wollen wurden mit der NMR-Impulsmethode untersucht. Daten über die Temperaturabhängigkeit der Spin-Gitter-(T 1)- und Spin-Spin-(T 2) Relaxationszeiten bei verschiedenen Hydratationsgraden wurden erhalten. Diese Daten werden auf der Grundlage des Zustandskontinuum-Modells und desEyringschen Wärmeaktivierungsgesetzes analysiert. Die aus der Analyse gewonnenen Parameter werden mit denen verglichen, die früher aus ähnlichen Daten über Wasser an unveränderter Wolle abgeleitet wurden. Aufgrund der Ergebnisse werden die Zustandsänderungen des absorbierten Wassers durch die Modifizierungen der Wolle diskutiert.
    Notes: Summary The states of water absorbed by wools that have been modified by (i) hydrolysis (ii) deamination (iii) ninhydrin addition and (iv) Dowfax addition were studied by the Nuclear Magnetic Resonance pulse technique. Data on the temperature dependences of the spin-lattice (T 1) and spin-spin (T 2) relaxation times at different levels of hydration were recorded. This data is analysed in terms of a continuum of states model and theEyring thermal activation law. The parameters resulting from the analysis are compared with those obtained previously from similar data on water absorbed by unmodified wool. From this some assessments of the changes in the state of absorbed water resulting from modifications to the wool are made.
