Abstract: A method for identifying objects including fixing tags to respective objects, each such tag comprising at least one optical emitter. The at least one optical emitter on each of the tags is driven to emit optical radiation of a respective color, selected from among the first plurality of colors emittable by the tags, during a respective time slot, selected from among a second plurality of time slots during which the tags may emit the optical radiation. A camera captures sequence of electronic images of an area containing the objects to which the tags are fixed. The electronic images in the sequence are processed in order to identify, responsively to the colors of the optical radiation emitted by the tags and the time slots in which the optical radiation is emitted, the objects to which the tags are fixed.

Abstract: This invention concerns a blowing lance and a procedure for the metallurgical treatment of molten steel in a converter with oxygen top blown over the molten steel. In order to monitor the treatment process the intention is for a temperature probe (21) to be integrated into the water-cooled lance head (2) behind the front end (11a) of the lance head and between the cooling chambers (5-10) formed in the lance head (2). The signal lines (26) of the temperature probe run through the lance body (1), more specifically, in a central protective pipe which has no fluid communication with the cooling medium or to the oxygen conducted by the lance.

Abstract: A motorized vegetation trimmer apparatus comprising an elongate main handle to which is connected a motor that rotatably drives a trimmer head located at a distal end of the handle. The trimmer head carries one or more radially outwardly projecting cutting members which cut vegetation as the trimmer head rotates. Each cutting member comprises a finite length of flexible strand. The cutting member is releasably gripped by a one-way gripping mechanism including a reciprocating gripping member and a compression spring that biases the gripping member into gripping contact with the strand.

Abstract: A clip-on picket fence cap assembly that can resist detachment of a plastic picket cap member from a plastic picket member when significant pulling force is applied to the cap member.

Abstract: A dust dispensing system comprised of a dip tube enclosing a much smaller outlet tube, both tubes fitted to countersunk holes in the plug base. A path for powder and air is created within the wall of a flexible container beginning at the area within the container through the longitudinal vent holes at opposite ends of the dip tube toward the inside center of the dip tube where two air/dust streams collide venting through the inward longitudinal opening of the outlet tube which is disposed at the point of convergence of the colliding streams and then the mixture continues to flow under pressure through the outlet tube and out the exit nozzle each time the container is squeezed. This action is repetitive and fully operational regardless of the device's orientation.
