Abstract: A differential gear mechanism is provided of the type including a gear case (17), at least one pinion gear (21), and a pair of side gears (27 and 29). Clutch packs (43 and 45) are disposed between the side gears and the gear case and are operable, when engaged, to retard relative rotation between the gear case and the side gears. The mechanism includes a fluid pressure actuated displacement mechanism (57) which, in response to an external signal (71) transmits its output displacement into axial movement of a plurality of input members (81). The axial movement of the input members has an acuating travel X and an actuating force F. A pair of lever members (85) receives the axial input from the input members 81, with each lever member pivoting about a fulcrum member (91) to transmit to each of the clutches a clutch actuating movement having an actuating travel substantially less than the actuating travel X, and an actuating force substantially greater than the actuating force F.

Abstract: Mécanisme de commande du débit pour réglage de chenille (34), qui détermine quelle est la tension optimale ou ''fléchissement contrôlé'' dans la chaîne à chenille (28) d'un véhicule de type à chenilles (10). Un piston (70) et une soupape correspondante (86) commandent le débit de fluide sous pression vers un cylindre de réglage de la chenille (48). Le mouvement du piston (70) tend la chenille (28) sans aucun fléchissement notable (''S'') et la rétraction par la suite du piston (70) permet d'obtenir la tension appropriée de la chenille avec un fléchissement de chenille optimal (''S''). L'opérateur du véhicule commande, depuis son poste (16), l'alimentation du piston (70) et de la soupape (86) en fluide sous pression. Les opérations traditionnelles de réglage de la chenille nécessitent un temps et un effort considérables et sont souvent déplaisantes, c'est pourquoi le réglage est souvent négligé, le résultat étant une usure plus rapide de la chenille et des éléments qui lui sont associés. Le présent mécanisme de réglage de la chenille (32) permet de régler avec justesse celle-ci d'une manière aussi simple que rapide.

Abstract: The improved corrosion-resistant steel plate with an organic coating comprises a steel plate having a zinc or zinc alloy plate layer which is overlaid with a chromate film which in turn is coated with an organic resin paint film. The organic resin coat comprises an epoxy resin which is prepared by reacting with an isocyanate compound and has a dialkanolamine incorporated into its bisphenol A skeleton, and silica. The dialkanolamine combines with a urethane-­modified epoxy resin to provide satisfactory curability at low temperatures; at the same time, it combines with the silica to provide a satisfactory film reinforcing effect. The organic coat formed of this composition can be effectively cured at low temperatures and yet it will neither dissolve nor soften upon swelling under the action of the alkali that is generated during cationic electrodeposition at the interface between the electrodeposited film and the organic coat. Thus, the organic coat has good paint adhesion, high corrosion resistance, as well as good workability and as-worked corrosion resistance and makes the steel plate suitable for use as an automotive part after painting.

Abstract: An accurate monitoring of the conditions of a perishable product is achieved by integrating two indicator types - a primary indicator which develops a color change as a result of cumulative time-temperature exposure and a threshold second indicator - into a single device. The combination of the two indicators in the same indicator device provides a human readible signal thate gradually and irreversibly develops color as a function of time and temperature and more closely monitors the actual condition of a deteriorative product than does a single indicator. Important features of this integrated monitoring device are reliability and printability. The primary indicator in the system is assisted in color development by the secondary indicator that is set to trigger at a predetermined temperature. When this temperature is reached or exceeded both indicator mechanisms function in an additive mode to cause a break in the typical Arrhenius curve, which a primary indicator alone produces. This can be used to signal actual rather than an apparent the end of a product life. The secondary indicia can be formulated to change very rapidly as would be needed to detect the thawing of a frozen product or modified so as to act more slowly, i.e. over at time-temperature range, and may comprise a substance that melts or changes some physical property at a given temperature.

Abstract: This invention relates to plants with genetically increased tissue culture and regeneration potential. These plants provide seeds and plants therefrom which also display the genetically increased tissue culture and regeneration potential. These plants are produced by initiating embryogenic callus culture on a defined culture medium; maintaining the embryogenic callus culture for a specific length of time; selecting for those embryogenic callus that have organized into discrete, more advanced globular structure, a portion of which germinates to form a plant; and regenerating the plant produced therefrom which is capable of seed production. Thus, this invention is also directed to methods for selecting plants with an genetically increased tissue culture and regeneration potential. This invention is also directed to a genetic factor derived from plants, which is capable of conferring an genetically increased tissue culture and regeneration potential to plant and to the plant's progeny.
