Title: Timed release of water-soluble plant nutrients
Inventor: LUTHRA NARENDER P
IPC: C05G3/00
Filed: 1993-06-07
Abstract: Products for the variable controlled release of water soluble agents are disclosed. The products have a core of water soluble agent and a first and second coating. The first coating has a permeability such that the agent can be released at a controlled rate, while the second coating has a relatively low water vapor transmission rate. Variation in the coating thicknesses and coating conditions result in nutrient release profiles which can be tailored to specific plant requirements. After application of the product, release of the agent is negligible, but after a predetermined time, e.g. one month or more, substantial release of the agent from the coated product begins. The product is particularly suitable for delayed, controlled release fertilizers.

Patent CA-2109925-A1 (CA)
Inventor: ADAMCZYK JANINA
IPC: G01N33/538
Filed: 1992-04-10
Abstract: This invention presents novel assay methods employing a capture reagent, involving a first binding member typically conjugated to a polymeric anion substance, and a solid phase material containing a reaction site comprising a polymeric ration substance having a nitrogen content of at least about two percent. In one embodiment a test sample suspected of containing the analyte of interest may be contacted with the capture reagent to form a charged capture reagent/analyte complex. The complex is then contacted to the oppositely charged solid phase to attract, attach, and immobilize the capture reagent/analyte complex. The use of a polycationic substance, having a nitrogen content of at least about two percent (excluding the counter ions), to prepare a suitably charged solid phase provides a solid phase that can be subjected to a greater extent of manipulation, such as multiple washes, without losing the capability to attract and retain the capture reagent.

Title: Resistored Sacrificial Anode Assembly for Metal Tank
Inventor: RODEN JAMES S
IPC: C23F13/10
Filed: 1993-12-13
Abstract: A sacrificial anode assembly is insertable into a metal water storage  tank  to  inhibit  corrosion  thereof  and  includes  a cylindrical metal anode member having an end retained within a cylindrical plastic insulating sleeve which, in turn, is captively retained within a metal cap portion of the assembly.  To regulate the amount of electrical current generated by the assembly during use thereof,  a barrel-shaped resistor is supported within the assembly and interconnected between its anode and cap portions.          The insulating sleeve has a generally U-shaped groove formed in a closed  end  thereof,  with  one leg  of  the  groove  extending diametrically across a central opening in the sleeve end that receives a core wire portion of the anode member, and the other groove leg extending generally chordwise relative to the sleeve end.  The resistor body is received within the chordwise groove leg, and a lead wire of the resistor is extended through the curved and diametrically extending groove portions and spot welded to the core wire portion received in the central sleeve end opening.  The configuration of the groove and the relative orientation of the resistor and sleeve opening causes the bent lead wire to form a resilient connection between the spot weld and the resistor body, thereby substantially reducing vibrational fatigue stress on the spot weld during shipping and handling of a tank having the anode assembly operatively installed thereon.

Title: Interactive color harmonizing methods and systems
Inventor: HAMLIN JAY F
IPC: G06T11/00
Filed: 1994-05-09
Abstract: ABSTRACT OF THE DISCLOSURE:    A substantially universal range of color standards over the visible spectrum is displayed for visual observation, comparison with extraneous colors and for interactive color processing in a color  computer  processing  system.  In  the  comprehensive  set, standardized colors are defined by hue supplemented by black and white content related in a visual format. Thus, a set of discrete hue values across the visible spectrum, typically 24, is displayed in a circular array for selections of hue. Each operator selected hue is displayed together with a range of related color samples obtained by combining black and white content to produce a range of colors associated with that hue. Thus a very large number of colors  may  be  viewed  for  visual  effect  and  comparison with extraneous color patterns to make selections of harmonized color combinations. Any of the color samples is available for interactive color processing,  such as editing,  graphical development,  and identification of colors and particularly in harmonized sets of colors for processing color images.  Colors in objects such as paints, draperies, paintings, dresses, etc. thus may be closely identified and standardized for faithful reproduction, editing or other interactive color processing procedures including harmoni-zation with related color schemes.
