摘要:
A computer supporting an active object program in a multi-purpose mode comprises a device (D) for simulating the time evolution of a medium. Said device (D) comprises a software dedicated for simulating by objects the joint evolution of certain activated objects comprising enaction objects defining autonomous spatiotemporal entities each of which represents a physical phenomenon and, when activated, interacts in a multi-agent medium via state objects defining interaction mediators providing a topological spatiotemporal support which forms a virtual environment representing a simulated medium and makes it possible to detect the interactions between the entities in space and in time and (ii) a simulation manager capable to operate by sequences on a selection of the enaction objects and to activate each enaction object only once for each sequence according to an order varying at least partially in a random manner from one sequence to the other, thereby enabling the spatiotemporal interactions dynamically evolve sequence by sequence between the enaction objects.

Color photographic motion picture elements adapted to form a multicolor photographic dye image and an integral, infrared-absorbing, dye sound track and comprising 1-hydroxy-2-N-(5-alkyl-thiazol-2-yl)-naphthamide couplers that are capable of forming quinone imine dyes absorbing infrared radiation in the spectral range from about 600 to about 1000 nm by reaction with an oxidized aromatic primary amino developing agent, the thiazol-2-yl group of said naphthamide couplers bearing a 4-para-C.sub.1 -C.sub.4 alkoxyphenyl group or a 4-para-C.sub.1 -C.sub.4 alkylphenyl group, the hydrogen atoms of said C.sub.1 -C.sub.4 alkoxy or C.sub.1 -C.sub.4 alkyl being unsubstituted or at least one of them having been substituted by a halogen atom.

A guide is provided for the buckets of an endless dredging line comprising an emptying station incorporated into the guide. A system comprising a pair of trolleys and a pulley system is provided to hold each bucket stationary at the emptying station for dumping. The endless line travels over the pulleys, some of which are mounted on the trolleys. When a bucket approaches the emptying station, the trolleys are actuated to travel in opposite directions so as to allow the endless line to move at its normal speed while holding the bucket at the dumping station stationary.

Compounds of the formula ##STR1## and pharmaceutically acceptable, nontoxic salts thereof or hydrates thereof, wherein R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are each hydrogen, halogen, lower alkyl or lower alkoxy, or any two of the groups R.sub.1, R.sub.2, R.sub.3 and R.sub.4, taken together with the carbon atoms to which they are joined complete a substituted or unsubstituted carbocyclic ring, and X is an oxygen atom, provided that R.sub.1, R.sub.2, R.sub.3 and R.sub.4 are not all simultaneously hydrogen, are useful for treating allergic conditions in humans.The compounds may be prepared by reacting a suitably substituted benzene derivative with an activated carbonyl group having a carbanion of the formula NC-CH-R, wherein R is a carboxylic acid ester group, and thereafter, if desired, converting the compound into a salt.

An automatic traction control system is provided for an electric or hybrid-electric vehicle. The automatic traction control system may be used with vehicles using two separately excited motors where the armatures of the motors are connected in series to provide differential control. The automatic traction control system monitors and compares the voltages across the armatures of the two motors. If the voltage differential exceeds a predetermined threshold, it is determined that one of the wheels is spinning and current is diverted from the motor driving the spinning wheel to the motor driving the non-spinning wheel.
