Filed: 2000-04-21
Granted: 2007-10-23
Abstract: Cette invention concerne un procédé permettant de tirer un cristal, lequel procédé permet d'abaisser un cristal germe avec précision en une position donnée dans un liquide en fusion lorsque l'on commence à faire croître un cristal, et de le tirer en continu dès que commence la croissance. Cette invention concerne également un dispositif prévu à cet effet. Le dispositif permettant de tirer un cristal en continu se caractérise en ce qu'il comprend un dispositif de traction linéaire (30) qui va tirer dans une direction verticale un cristal germe (12) et un cristal de type ruban (16) que l'on a fait pousser à la pointe dudit cristal germe. Le dispositif décrit dans cette invention comprend également un mécanisme de traction (40) qui va agripper et tirer continuellement le cristal de type ruban, ainsi qu'un mécanisme de commutation qui va assurer la commutation en traction continue par le mécanisme de traction (40) une fois que le cristal germe tiré par le dispositif de traction (30) a dépassé le mécanisme de traction (40). Ce dispositif comprend enfin un mécanisme de coupe (39) permettant de couper et de séparer le cristal germe (12) et le cristal de type ruban (16).

Abstract: The invention relates to a capillary mattress which is specially designed for sub-irrigation of pot crops. The structure of said capillary mattress has a dry top surface and is therefore free from problems caused by colonies of algae and insects that are associated with existing capillary mattresses. The inventive mattress consists of three distinct layers. The first layer forms the top of the mattress. It is made of a thin polymer sheet (2) containing a multitude of little holes (3) upon which the pots are placed. The center layer is made up of a sheet of resilient foam (4) which has open cells and which can be compressed and enables water to flow easily therethrough. The bottom layer is made from a mass of absorbent matter (5) which can absorb water and ensure both a good division and distribution thereof. When used, the capillary mattress is placed or installed on a planar, approximately level, impermeable surface. A certain number of perforated water supply pipes run between the surface upon which the mattress rests and the latter. The water supply pipes emit water at different points along the length thereof and provide water to the mass of absorbent matter (5) of the mattress. Pots (6) containing crops are placed at any desired point on the top surface of the capillary mattress. The sheer mass of the pots compresses the foam and reduces the dimensions of the cells thereof, thereby bringing the polymer sheet which forms the top level of the mattress closer to the mass of absorbent matter forming the lower layer. The decrease in the dimension of the cells of the resilient foam forming the center layer facilitates capillary ascension of water between the bottom layer of the mattress which is full of water and the top layer.

Abstract: The antimicrobial efficacy of N-chlorosulfamate solutions, namely buffered aqueous combinations of HClNSO3-(mono-N-chlorosulfamate) and Cl12NSO3 (di-N-chlorosulfamate), herein referred to as "stabilized hypochlorite", can be markedly enhanced by the addition of certain organic dopants. The dopants themselves are select hypochlorite stabilizing agents, which are known to readily form stable organochloramides when reacted with "free" hypochlorite (HOCl or NaOCl). Highly effective antimicrobial enhancing dopants include 5,5-dialkyl hydantoins, arylsulfonamides, and succinimides. Examples of these include 5,5-dimethylhydantoin, benzenesulfonamide, and succinimide. Other, less effective dopants include glycolurils. Generally, the dopant is present in a minor mole fraction, relative to the molar amount of stabilized hypochlorite present in the enhanced antimicrobial solution.

Abstract: A system for harvester speed control includes a header position sensor connected to a processor. If the header is lowered during crop cutting, harvester speed is immediately decreased to prevent a sudden increase in material downstream of the feeder house input. The percentage speed reduction preferably is approximately equal to the estimated percentage increase in material for the given height change as set manually by the operator, calculated during a brief calibration process, or derived utilizing an adaptive learning technique. Signals from a throughput transducer and from harvesting quality transducers such as grain loss transducers are communicated to the processor to determine desired harvester speed.
