Patent CA-2037106-A1 (CA)
Inventor: BYRON DAVID L
IPC: B24B49/02
Filed: 1991-02-26
Abstract: A computer numerical control machine system for edging lenses controls the rotation and displacement of a lens workpiece with respect to a edging tool in accordance with a lens shape stored in memory.  The system continuously translates the lens workpiece axially across the surface of the wheel to uniformly distribute wear across the wheel surface, reducing the need to dress the edging tool.  The system compares the lens size with predetermined dimensions and compensates for any difference by automatically adjusting the lens trajectory during the edging of subsequent lens workpieces, permitting the edging tool to wear down without appreciable errors in lens size.  The system controls the edging tool speed, the lens rotation rate, the lens axial feed velocity and the grinding force between the lens workpiece and the wheel at each discrete point during the entire lens edging operation to optimize production while preventing overheating of the lens workpiece.  The optimum values for these parameters are empirically determined in a preparatory programmed trial and error learning process of the invention.

Title: Method for manufacture of swiss cheese
Inventor: POPE BRENT K
IPC: A23C19/028
Filed: 1991-02-27
Abstract: In accordance with the method of the present invention for manufacture of Swiss cheese from milk, the fat level of milk is standardized to about 3.5%. The milk is subjected to membrane processing by ultrafiltration and diafiltration to provide a retentate with particular characteristics. The retentate is then fermented with a particular blend of a coccus culture and a high level of a rod culture. The usual propionic acid-forming micro-organism, such as Propionibacterium shermanii, is used. The fermentation is desirably carried out at high temperatures to achieve the results of the invention. The fermented retentate is then evaporated to a solids level desired in the finished Swiss cheese, which is generally in the range of 35% to 41% moisture. The fermented axed evaporated product is suitable for packing into containers to be cured and to provide Swiss cheese without further manipulation or treatment. The particular conditions are necessary to provide the desired Swiss cheese.

Abstract: Dispositif électromoteur léger présentant un rapport puissance-poids élevé et capable de fonctionner en tant que moteur, alternateur ou génératrice à bon rendement.  Le dispositif comporte un ensemble produisant un flux magnétique comprenant des éléments magnétiques espacés (32, 33) et une armature (82) formée en enroulant un fil conducteur non magnétique (84), tel un fil de cuivre, sur un noyau acheminant le flux (86) ou les éléments de la barre-stator.  Les éléments (86) présentent une forme permettant de former un blindage contre les courants de Foucault pour les enroulements (84) et fournissent deux surfaces à rayonnement thermique.  Tous ces éléments permettent au dispositif de fonctionner avec une perte minimale due aux courants de Foucault, et un refroidissement maximal par rayonnement et par convection.  La dispersion des enroulements (84) de l'armature et des éléments acheminant le flux (86) constitue une autre mesure pour éviter de créer des courants induits opposés.
