Abstract: A compound, or a pharmaceutically acceptable salt or isomer thereof, of Formula I: wherein R is hydrogen, alkyl, substituted alkyl, alkenyl, or substituted alkenyl; R1 is hydrogen, alkoxy, or substituted alkoxy; R2 is hydrogen, alkyl, or substituted alkyl; and R3 is hydrogen, alkyl, or substituted alkyl.

Abstract: The invention relates to an electronic device (1) configured for opening/closing a door (P) or similar, from a light signal defining an opening and/or closing code emitted by a movable transmitter having means for emitting said light signal, said electronic device having an electric lock comprising: a lock cylinder (2) with a stator (20) and a rotor (21), as well as an electric actuator (3) configure to modify the state of the electric lock, means for receiving signals configured to detect light pulses comprising a receiving diode (4), a control unit (5) connected to the receiving diode (4) and connected to the electric actuator (3), configured to decode the light pulses detected by said receiving means and to determine a control of the electric actuator (3). According to the invention, the diode (4) is advantageously protected and all of the means (3, 4, 5) are self-supporting with the lock cylinder (2) in order to facilitate the installation of it as a conventional lock cylinder.

Abstract: The disclosure relates to a robot that has an articulated arm for moving an end in an N-dimensional space including at least N+1 motorized articulations, and a computer for controlling the movements of the motorized articulations. The computer controls a first step of prepositioning the terminal end of the articulated arm and a second step for its fine positioning.

Abstract: A backup locking system for a thrust reverser door comprises a catch pivotally mounted by a pivot pin to a fixed structure of the thrust reverser. A hook with a self-locking profile is provided at the free end of said catch for cooperation with a locking interface on the door in the event of failure of the normal locking systems. At its other end remote from said hook, the catch has a heel ending in a part-cylindrical surface which is concentric with said pivot pin. The catch is urged against the locking interface by a piston rod which presses against a front face of said heel under the force of a spring acting on a piston to which said piston rod is attached. When the rod is retracted, a double lever positively moves the catch toward a minimum opening angle, at which point the door can be opened. An unlocking spring causes the full opening of the catch to maximum open position when an opening lever is released.

Abstract: In a turbojet thrust reverser comprising, in an annular section of an outer cowling of the turbojet, a number of movable doors which, in an inactive position during operation in a forward thrust configuration, close off passages separating rigid spars of a fixed structure, there is provided, between two adjacent doors, a locking system which allows substantially simultaneous opening of the two doors. The locking system comprises, for each door, at least one hook mounted on the fixed structure so that it can be pivoted by an olive secured to the door between a door locking position and an unlocked position during opening or closing movement of the door. The two hooks of the locking system are rotationally interlinked by a mechanical linkage device, for example link rods, so as to prevent the unlocking of one door if the other door is closed.

Abstract: The machine incorporates at least two central rollers appropriately driven, and adjustable in height in order to disengage a finished object. In combination with the central rollers, side rollers are positioned in space by means of jacks. The positioning is permanently registered by sensors working in connection with a computer and probes positioned between the central rollers and the side roller for providing information compared to instructions from the computer in order to correctly position the side rollers.

Abstract: The invention relates to a machine for automatically welding and/or cutting the junction point between a main pipe and a secondary branch pipe placed thereon. This machine comprises a positioning support on which the main pipe is placed. The positioning support comprises two servomotors which drive the main pipe in rotation about the longitudinal axis of the pipe and about a second horizontal axis perpendicular to said longitudinal axis. The machine comprises a travelling gantry crane which bears three carriages movable by three servomotors along three axes rectangular with each other, one of which is vertical. One of the carriages bears a welding or cutting head.

Abstract: The ship stabilizer comprises at least two retractable fins mounted on both sides of the hull of the ship, housings being formed within the hull below the floating line of the ship for engaging therein the fins in the retracted condition.
