Patent CA-2191044-A1 (CA)
Inventor: MEIBACH RONALD LOUIS
IPC: A23C19/072
Filed: 1996-11-22
Abstract: The present invention is directed to a method for making a particulate natural cheese suitable for preparation of processed cheese, as well as for use as a natural cheese, such as a snack food and shreds for cheese toppings. In the method, a milk coagulum is provided. The coagulum is cut to provide particulate cheese curds and whey. The cheese curd is cooked while undergoing agitation. Thereafter, whey is drained from the cheese curd while the cheese curd is continuously agitated. The cheese curd is then cooled or dried sufficiently to maintain the cheese curd as separate particles. Agitation may be used during or immediately after the cooling or drying step to insure separation of the cheese particles. The cheese particles formed may form friable lumps but do not knit during storage. The cheese particles are then packed into relatively large containers holding from about 1,000 to about 2,500 pounds of cheese curd or may be bulk packed in rail cars or trucks. The containers are preferably bulk bags with a liner of plastic or other disposable material. The liners are gas flushed before and during filling to reduce the oxygen content and inhibit mold growth. The liners may be disposed of after use in transporting the cheese curd to a final destination. The bulk bags are reusable with fresh liners.      In an alternate embodiment, the cheese curd is drained without agitation to provide a cheese mat. The cheese mat is milled into cheese pieces prior to the cooling step.

Title: Anti-falsification paper and a method of manufacture thereof
Inventor: IWASAKI TADAHIRO
IPC: D21H21/40
Filed: 1997-03-07
Abstract: Anti-falsification paper in which a thread is exposed at window portions provided on the surface of the paper, and which does not produce any cockles even when wound up continuously in a roll and has good appearance in terms of design is provided. This anti-falsification prevention paper is combination paper having at least two paper layers including an outermost layer and the other layer. Window portions are formed in the outermost layer at intervals in a longitudinal direction of the paper. In the window portions there are formed watermarks of letters or pictures, and a thread inserted between the outermost layer and the other layer is exposed at these window portions. The ratio between the length (X) of the window portions in the longitudinal direction of the paper and the length (Y) in the same direction of non-window portions between the window portions is set at 3:1 to 1:2 to securely prevent the formation of cockles during the winding of paper. This setting of the length ratio of the window portions to the non-window portions also offers preferable effect on the design.

IPC: G06F21/00
Filed: 1996-07-08
Abstract: L'invention concerne un système visant à empêcher la duplication d'un logiciel, le logiciel à protéger étant placé en deux parties dans le système informatique. Une première partie (120) est stockée dans une mémoire non volatile, par exemple un disque dur ou une disquette à l'intérieur du système informatique (100), et une seconde partie est stockée et exécutée dans un "système de codage matériel" (122) qui est rattaché au système informatique (100). La seconde partie est stockée dans une mémoire vive volatile (206) et est effacée lorsque le "système de codage matériel" (122) est mis hors tension, ou lorsque le logiciel cesse son exécution. Ceci implique que la seconde partie du logiciel soit rechargée à chaque fois que le système de codage matériel (122) est mis sous tension. En général, la seconde partie du logiciel est chargée à partir d'un réseau (130), ou à partir d'un réseau câblé. Le rechargement de la seconde partie dans le système de codage matériel (122) représente donc une opération banale tant que l'utilisateur est un abonné actif du réseau (130) ou du réseau câblé.

Title: Bone cutting guides for use in the implantation of prosthetic joint components
Inventor: MASINI MICHAEL A
IPC: A61F2/38
Filed: 1996-11-01
Abstract: Improved bone cutting guides enable a surgeon to better gauge required resection characteristics. In one embodiment at least a portion of the guide (204) is transparent (208, 210), thereby enabling the user to optimize cut estimates and to visualize the resection as it is being performed. In another embodiment, at least a portion of the outer surface of the body (404) is shaped to interact with another bone or prosthetic element associated with a joint, thereby enabling the device to function both as a trial and as a cutting guide. In this embodiment (404) as well the guide may be at least partially transparent to improve visualization. Although primarily intended for use in femoral-side knee arthroplasty, the invention is applicable to any procedure which might benefit from improved bone-cutting accuracy.

Abstract: Preventing the excessive supply of the release agent, and simultaneously preventing the dripping of the excessive release agent when applying a release agent, in order to prevent the offset by the heat roll. In a fixing device having a heater lamp mounted as a heat source in the interior of a cored bar of a heat roll, wherein the temperature is maintained to a heat-fixing temperature by controlling the electricity being supplied to the heater lamp, an application roll is mounted so as to contact the heat roll for a uniform application of a release agent, and an application member for supplying and applying the release agent to the application roll is mounted so as to contact said application roll, while a blade for limiting the release agent being applied to the roll is mounted thereto. The application member and the blade are positioned so that the opposing end surfaces thereof are adjacent to each other. In this way, the application region in the tip portion of the application member is in a saturated state, and the excessive supply of the release agent is limited, which leads to the stabilization of the supply quantity, and the prevention of generation of an excessive release agent.
