Title: Process for optimizing and balancing the composition of the feed given to a ruminant
Inventor: LINDBERG JAN E
IPC: A23K1/18
Filed: 1990-06-27
Abstract: The invention relates to a process for optimizing and balancing the composition of the ration feed given to a ruminant by judging the nutrient status of the fore-stomachs with reference to energy and protein. The process is characterized by the determining the ruminant excretion of urea and allantoin and emanating from the obtained combined information of the urea and allantoin content adjusting the protein and/or energy content of the ration feed to an optimum level. Preferably the excretion of allantoin is measured in relation to creatinine, that is to say, as an allantoin/creatinine ratio.

Title: Suspension polymerization of vinyl chloride
Inventor: AMANO TADASHI
IPC: C08F14/06
Filed: 1992-09-02
Abstract: ABSTRACT OF THE DISCLOSURE    An improvement is proposed in the method for the suspen-sion polymerization of vinyl chloride, according to which the poly-vinyl chloride resin prepared by the reaction is advantageous in respect of the low initial coloration of the shaped articles there-from even when the polymerization reaction is conducted in the presence of a monomer-soluble polymerization initiator in an amount increased with an object to accelerate the polymerization reaction for improved productivity.

Title: Procede de separation d'ilmenite
Inventor: WALPOLE ERNEST A
IPC: C22B1/02
Filed: 1991-08-28
Abstract: Méthode pour améliorer l'ilménite provenant de gisements de sables ou de concentrés minéraux; elle se compose d'un grillage magnétisant (16) à lit fluidisé mono-étage. On utilise une température de 650 à 900 °C avec un excès de combustible carbonacé (comme le charbon, CO ou des hydrocarbures) pour obtenir une atmosphère dans laquelle le potentiel d'oxygène est contrôlé, ce qui donne un produit à susceptibilité magnétique constamment élevée. Le grillage a déjà été employé auparavant, mais l'étape de séparation magnétique (18) du procédé actuel nécessite une intensité moindre, et la récupération est meilleure (même pour les résidus produits par l'ancien procédé de grillage). Le recuit du produit grillé (17) améliore la susceptibilité magnétique. Les ilménites comportant des inclusions ou des salbandes de silicates sont encore améliorées grâce à un broyage après la séparation magnétique, avant la scorification ou l'utilisation comme alimentation pour la production de rutile synthétique. L'étape du grillage active la lixiviation de l'ilménite dans la production de rutile synthétique.

Inventor: SCOTT DONALD S
IPC: C13K1/02
Filed: 1993-03-10
Abstract: A process is described for the production of anhydrosugars, such as levoglucosan (1,6-anhydro-.beta.-D-glucopyranose), from liquids obtained by the fast thermal pyrolysis of pretreated lignocellulosics or celluloses.  In this process, the pyrolytic liquids containing the anhydrosugars are produced with a substantially reduced amount of lignin-derived components by using as feedstock materials which have been previously delignified and then pretreated, or by preferential oxidation of the lignin fraction of a pretreated biomass during pyrolysis.  The preparation from pretreated biomass of pyrolytic liquors from which the lignin derived chemical products of fast pyrolysis are absent or in low concentrations permits simpler and more economical recovery of crystalline levoglucosan and other anhydrosugars, or a more economical preparation of readily fermentable aqueous sugar solutions therefrom.  A new procedure for the recovery of crystalline levoglucosan from such solutions is also described.
