Abstract: L'invention concerne un procédé de production de papier de sécurité comprenant un élément de sécurité. Le procédé consiste à former à l'état humide un papier comportant un ou plusieurs éléments de sécurité, à lui appliquer une solution de collage, puis à appliquer sur l'une ou les deux faces du papier encollé un revêtement comportant un polyuréthane non pigmenté. Ce polyuréthane non pigmenté peut éventuellement comporter un additif fonctionnel, à condition que la présence de l'additif fonctionnel n'augmente pas l'opacité du papier de plus de 1 %. Après application du polyuréthane, le papier est séché. La composition de revêtement forme, lorsqu'elle est coulée sur une surface de verre, une pellicule ayant une dureté de König de 15 à 130 secondes, et satisfait aux essais de résistance à l'eau définis par les étapes suivantes: a) la totalité de la préparation destinée au revêtement est coulée sur une plaque de verre afin de produire une pellicule ayant un poids à sec de 80 g/m<2>; b) la pellicule est initialement séchée à 23  DEG C. Lorsqu'elle est hors poisse, elle est séchée encore pendant une heure à 80  DEG C; c) la pellicule est pesée avant d'être mouillée, et de faire l'objet d'une mesure de résistance à la traction et de module de Young, et d'un contrôle visuel servant à détecter une éventuelle altération de sa transparence; d) un échantillon de la pellicule est bouilli dans de l'eau contenant 10g/litre de Na2C03 pendant 30 minutes; e) la pellicule est ensuite rincée dans l'eau froide et les étapes b) et c) sont effectuées à nouveau. Lorsque la pellicule est séchée et pesée à nouveau, elle satisfait aux critères suivants: i) la résistance à la traction et le module de Young à l'état humide de la pellicule bouillie sont au moins égaux à 90 % des mêmes caractéristiques de la pellicule initiale à l'état humide; ii) le film ne présente pas d'altération perceptible de transparence; et iii) le poids à sec de la pellicule est au moins égal à 98 % du poids initial.

Abstract: An aglucone isoflavone enriched vegetable protein whey, whey protein material, high genistein material, high daidzein material, and aglucone isoflavone material are provided, as well as a process for producing the same from a vegetable protein whey. Isoflavone conjugates in a vegetable protein whey are converted to isoflavone glucosides by treating the whey at a temperature and a pH for a period of time sufficient to effect the conversion.   The isoflavone glucosides are converted to aglucone isoflavones by enzymatic reaction to produce an aglucone isoflavone enriched vegetable protein whey.      Aglucone isoflavone whey protein material is recovered from the aglucone isoflavone enriched vegetable protein whey. A high genistein content material, a high daidzein content material, and an aglucone isoflavone material are produced from an alcohol extract of the aglucone isoflavone whey protein material.

Abstract: An optic cell 20 for use in the cavity of a high-power laser comprises an optic housing 22 which defines c first laser beam aperture 26.  An optic element 32 such as a mirror or lens is disposed within the optic housing.  A first  indium layer 30 is between and in abutting contact with the optic housing and the optic element.  An optic cover 40 defines a second laser beam aperture 46 therethrough substantially in alignment with the first laser beam aperture to form a window 47 of the optic element through which a laser beam passes.  A second indium layer 48 is between and in abutting contact with the optic element and the optic cover.  The optic housing and the optic cover are typically formed of aluminum or copper to passively cool the optic element.          The first and second laser beam apertures are configured to minimize the heat transfer distance between the optic element and the optic housing and optic cover, are to allow the laser beam to pass through the optic element without striking metal portions of the optic cell.  An optic cell mount 6 removably clamps the optic cell in the laser cavity, and  includes cooling elements 56, 76 for cooling the optic cell to control the optic element temperature.

Title: On-the-go from the tractor seat windrow adjustment
Inventor: HANSON BRIAN
IPC: A01D57/00
Filed: 1998-06-19
Granted: 2001-11-27
Abstract: The swathboard of a windrower can be remotely adjusted from the tractor seat and on-the-go using an electro-mechanical actuator or other remotely operated actuating device. When the swathboard is adjusted to its fully raised position, the stream of crop materials issuing from the conditioner rolls bypasses the swathboard and engages the forming shields to be converged into a windrow having a width determined by the outlet formed between the rear ends of the shields. At the other extreme, when the swathboard is fully lowered, the stream impinges against the swathboard and drops to the ground in a wide swath without ever engaging the forming shields. In any one of a number of intermediate positions, the swathboard can be used by the operator to deflect the stream to engage wider or narrower portions of the forming shields, thus controlling the width of the windrow.
