摘要： A slip control system for vehicles having spaced apart differentially driven wheels (200, 202) including means (220) for calculating wheel slip according to the ratio of wheel speeds, means (242, 230, 232) for entering a slip control mode wherein a braking force is applied to the slipping wheel and incrementally varied on a periodic review basis according to recalculated slip values. If slip increases or holds steady, the brake force is incrementally increased. As slip becomes less, the brake force is incrementally reduced, the particular increments of force reduction being selected in accordance with successive measurements of slip. A drive shaft signal (226) is compared to the high wheel speed signal to identify a wheel speed transducer failure.

摘要： A vehicle (10) having an operator's cab (12) which may be tilted to gain access to parts of the vehicle located beneath the cab, has a braking mechanism which automatically brakes the vehicle (10) when the cab (12) is tilted so that maintenance and tests may be conveniently performed on the components under the cab (12) while the engine is running. The mechanism consists of a pedal (34) and a linkage (40, 44, 48) carried by the cab (12). The linkage includes a lever arm (40), a rod (44) and a lever arm (48) connected to a brake actuating means (50). The pedal (34) and linkage are operated to activate the brake actuating means (50) for conventional braking and are carried with the cab (12) during tilting of the cab to automatically activate the brake actuating means (50) to set the brakes.

摘要： Un différentiel de direction pour véhicule (10) comprend un carter (12) définissant une chambre (76), une ouverture (78) sur l'axe transversal (36) en communication avec la chambre et une surface de montage (80) autour de l'ouverture (78). Un engrenage de pignon d'entrée (14) et un engrenage conique (18) entraîné par l'engrenage de pignon (14) sont reliés de manière rotative à l'intérieur du carter (12) en prise à angle droit par un corps (20) fixé de manière libérable sur la surface de montage (80). Une ouverture radiale (82) est définie dans le carter (12) et un moteur de direction (16) possède un arbre (88) qui s'étend au travers de l'ouverture radiale (82) en prise d'entraînement avec l'engrenage de pignon (14), le corps (20) supportant le moteur de direction (16). Le corps (20) comprend un bras (110) et un collier (122) fixé de manière libérable au bras (110) pour supporter le moteur de direction (16).

摘要： Un système de contrôle d'un paramètre de moteur, par exemple la pression d'huile, qui varie en fonction de la vitesse du moteur, contrôle ce paramètre par rapport à une valeur supérieure et à une valeur inférieure. La pression d'huile est détectée par un transducteur (122) et la pression détectée est contrôlée par une paire de comparateurs (252, 266) comparant la pression d'huile détectée avec les tensions de référence correspondantes aux valeurs supérieures et inférieures. Les tensions de référence peuvent être modifiées sélectivement par un commutateur (124) afin de changer les valeurs prédéterminées de pression. Les sorties des comparateurs (252, 266) commandent un indicateur (16) qui réagit lorsque la pression contrôlée est inférieure à l'une des valeurs prédéterminées. Un circuit (75) est prévu pour empêcher l'actionnement de l'indicateur (16) par le comparateur (252) contrôlant la pression par rapport à la valeur supérieure lorsque la vitesse du moteur est inférieure à une valeur prédéterminée. La sortie du comparateur (266) réglant la pression par rapport à la valeur inférieure commande un compteur horaire de service (18) afin d'indiquer le temps qui s'est écoulé pendant que le moteur tournait.

摘要： A method and apparatus for abrasively machining a workpiece (12) includes the establishment of an eddy-current in the workpiece (12) at an area (33) where an abrasive tool (14) contacts the workpiece (12). Heretofore it has not been possible to adaptively control an abrasive machining operation as a function of changes occurring in the microstructure of the workpiece (12) during the machining operation. In particular, it has not been possible to detect non-visible grinder burn on the surface of a workpiece during a grinding operation. The present invention solves the above problem by providing an abrasive machining apparatus (10) having a means (32) for establishing an eddy-current in a workpiece (12) at an area (33) where a tool (14) contacts the workpiece (12) and sensing any change in the eddy-current in response to change in the microstructure of the workpiece (12) resulting from the abrasive machining operation. The method and apparatus of the present invention is particularly useful for grinding hardened ferrous metal workpleces without incurring grinder burn defects.

摘要： A flexible face seal assembly (10) is provided for a joint laving a first member (15) which is both pivotable about and axially movable along an axis relative to a second joint member (16). The seal assembly (10) is disposed within an annular recess (23) of the first joint member (15) and includes an annular seal (30) of a flexible, wear resistant material and a metallic load ring (31). The seal has an axially movable sealing portion (34) with an annular seal lip (38). The load spring (31) is disposed behind the sealing portion (34) for urging and maintaining the seal lip (38) in sealing engagement against a sealing surface (22) of the second joint member (16). A rigid stiffener ring (40) is moulded into the sealing portion (34) of the seal (30) and is positioned within the sealing portion (34) to provide an intervening wall portion (41) of the resilient material of the seal (30) separating the stiffener ring (40) from direct force transmitting contact with the load spring (31) to prevent wear and fretting of the load spring.

摘要： A fuel nozzle (18) for a gas turbine engine (10) permits alternate use of different fluid fuels such as gaseous or liquid fuels without intermixing until delivery of the fuel to the combustion chamber (16). The nozzle provides concentric fuel delivery passages (28, 60) and allows for differing rates of expansion between the two passages.
