Abstract: An improved agricultural carrier and a method of making the carrier is disclosed. The granular carrier is adapted for carrying a low-melting chemical, specifically pesticides. An aromatic solvent is used to dissolve the low-melting chemical, before combining it with the carrier. The granular carrier unexpectedly exceeds its liquid holding capacity for the low-melting chemical.

Abstract: Traveling-wave piezoelectric motor comprising at least one stator (1, 2) consisting of an annular body with which are associated two groups of piezoelectric elements (3, 4) in the form of rods in permanent contact with the stator and with a connector (7) for their excitation, and a rotor (12, 13). The rods (3, 4) are housed in a drum (5, 6) made of an insulating material whose holes have a constriction (24) for holding the rods.

Abstract: A vehicle rack for ladders or other elongated cargo includes a carrying surface and a structure which permits the carrying surface to be adjusted between two fixed positions, both of which can be used for transporting ladders or other elongated cargo. The rack consists of a pair of frames, and each frame includes assemblies generally formed from elongated members. The frame's post assembly has a foot portion which can be releasably secured to the vehicle and an upper portion to which an arm assembly is rotatably connected at one of the arm assembly ends, thereby forming an inverted L-shape. A brace has one end connected to a mid-point of the post assembly and another end connected to a mid-point in the arm assembly. The brace can be attached to one or the other of two attachment areas to position the arm assembly in either of the two fixed positions.
