Abstract: A connector for connecting a floating module to a beached module of a modular wharf, the connector comprising: a resilient member adapted for resiliently opposing movement of the floating module toward the beached module; a sliding connector for slidably connecting said floating module to said beached module to allow vertical movement of the floating module relative to the beached module during tides of said body of water while restricting horizontal and lateral movement of said floating module.

Abstract: An animal feeder is comprised of a feed hopper for the containment of animal feed and having feed discharge drums located in a lower section of the hopper. The drums are provided with feed transport cavities to transport feed from the hopper to a feed trough disposed below the hopper. The drum is maintained at a predetermined inoperative position by means of a weighted bar element which is actuated by an animal to displace the drum and transfer feed from the hopper to the feed trough. A feed arresting bar is horizontally secured at a predetermined location in each feed transport cavity to obstruct free flow of feed when the drum is in motion to a discharge position.

Abstract: A method and apparatus for classifying articles according to their color, wherein a first pair of wavelengths is selected on a plurality of light reflection curves in terms of a reflected light wavelength spectrum. An article to be inspected is illuminated with light comprising the first pair of wavelengths and light reflected therefrom is measured to detect light reflection values corresponding to this first pair or wavelengths. A primary signal is produced, which represents a resulting difference between the detected light reflection values, this signal being indicative of the color of the inspected article. At least one secondary wavelength is selected on the reflected light wavelength spectrum, and the inspected article is illuminated with light comprising this secondary wavelength and light reflected therefrom is measured to produce a secondary signal which is further indicative of the color of the inspected article.

Abstract: Method and apparatus for sensing the color of articles wherein a first pair of wavelengths is selected on a plurality of light reflection curves in terms of reflected light wavelength spectrum, these curves being associated with a plurality of articles constituting a sample representative of the color range to be sensed. The first pair of wavelengths delimits a first range of wavelengths corresponding to light reflection values in these curves, the light reflection values in each of the curves being in a substantially linear relationship over said first range of wavelengths. Each article to be inspected is illuminated with light comprising the first pair of wavelengths, and the light reflected therefrom is measured to detect light reflection values corresponding to the first pair of wavelengths. A primary signal is produced which represents a resulting difference between said detected light reflection values, this signal being indicative of the color of the inspected article.
