Abstract: Recombinant DNA constructs comprising a DNA coding for transcription into an RNA sequence of tospoviruses or into RNA sequences related thereto, the use of such DNA constructs to transform plants having reduced susceptibility to tospovirus infection and probes for the isolation of tospovirus or diagnosis of pant tospovirus diseases.

Abstract: Recombinant Impatiens Necrotic Spot Virus (INSV) DNA constructs comprising an INSV DNA coding for transcription into INSV RNA sequences or into RNA sequences related thereto, the use of such DNA constructs to transform plants having reduced susceptibility to INSV infection and probes for the isolation of INSV or diagnosis of plant INSV related diseases.

Abstract: A transport container has three wall panels (14, 15, 16) which can be folded in one above another in layers, and also a fourth wall panel (29) mounted on a slide member (28). This fourth wall panel (29) can, when required, be stowed beneath the base panel (12) in order to make possible unhindered access into the container from the front side.The container can be stored, with a saving of space, in the folded-up state.

Abstract: A reciprocating device for spray painting an object includes a plurality of mounting arms each having one end releasably retaining a spray painting device and an opposite end releasably coupled to one of a pair of spaced apart generally parallel vertically extending posts. The posts are attached to a driving mechanism which includes a servomotor coupled to one end of a crank arm having its other end rotatably coupled to a sliding block engaging a generally horizontally extending rod to convert the rotary motion of the motor to vertical motion of the rod. The rod is coupled to the ends of the posts and the motor is controlled as to its direction of rotation, speed of rotation and degree of rotation to define the excursion of the reciprocating movement and the speed of the movement. The assembly is mounted on rails for movement toward and away from the object to be painted by another driving mechanism.

Abstract: An improved wrist mechanism for a robot arm is disclosed. A first drive mechanism is provided which includes a hollow upper knuckle portion adapted for rotation about a first axis. The upper knuckle portion terminates in an angled end. A second drive mechanism is provided which includes a first hollow torque tube journalled in the upper knuckle portion for rotation relative thereto and a lower knuckle portion having an angled end journalled to the upper knuckle portion curved end for rotation about a second axis. The first torque tube and the lower knuckle portion engage each other for rotation together, and the first and second axes of rotation intersect at a first point. A third drive mechanism includes a second hollow torque tube journalled in the first torque tube for rotation relative thereto, an intermediate drive member journalled in the lower knuckle portion curved end, and an output tube journalled in the lower knuckle portion for rotation about a third axis.
