Title: System for assigning discrete time periods for dye applicators in a textile dyeing apparatus
Inventor: COX STEVEN WAYNE
IPC: D06P5/00
Filed: 1991-02-14
Granted: 2002-05-28
Abstract: A control system for a textile dying apparatus processes and distributes digitally encoded pattern information. A substrate is moved on a path along which the surface of the substrate comes into operative range of a plurality of arrays arranged along the path of the substrate. Each of the arrays has a plurality of individual dye applicators capable of selectively projecting a stream of dye onto a predetermined portion of the substrate corresponding to a pattern element in a pattern composed of a pattern element matrix with a plurality of pattern elements in each of a plurality of pattern rows. Each pattern element is associated with a visually distinct pattern area. The dye applicators project dye for a time period determined by the pattern information. The method first determines a set of initial values. From the initial values it generates a firing command matrix having, for each dye applicator in each array, a firing command sequence corresponding to the pattern element to which that dye applicator may apply dye in each pattern row. Finally, the method allocates, for simultaneous transmission to each dye applicator in each array, the firing command sequence in the firing command matrix corresponding to the pattern element in the pattern row to be applied to the predetermined portion of the substrate that is passing within operative range of the dye applicator at the time of transmission.

Filed: 1991-12-19
Granted: 2000-10-17
Abstract: The invention relates to a method for fine tuning the resonant frequency of a filter in a combiner, which is provided for combining signals from several radio channels, to the carrier frequency of an input signal to the filter.      The power of the output signal from the filter is measured in a narrow frequency band around the carrier frequency of the input signal. Furthermore, the power of the signal reflected by the filter is measured in a narrow frequency band around the carrier frequency of the input signal.      Thereafter a measure of the ratio between the two power measurements is formed. The resonant frequency of the filter is adjusted so as to maximize this measure.
Patent CA-2071163-C (CA)
Inventor: TROCINO FRANK S
IPC: C08G12/46
Filed: 1992-06-12
Granted: 1996-03-26
Abstract: A fire-retardant composition for rendering a combustible hydrophilic substrate resistant to combustion and flaming is disclosed.  Also disclosed are processes employing said composition for rendering a hydrophilic substrate resistant to combustion, as well as structural material made fire-resistant by such a process.  The composition is a thermoset formed by combining two resins, which can be either made and stored separately for long periods until use or stored as a partially polymerized liquid mixture.  The resins are water soluble and heat-curable to form the thermoset.  The first resin comprises polyols derived preferably from a carbohydrate such as maltodextrin having substituent groups occupying a portion of the available hydroxyls derived from monoammonium phosphate, urea, phosphoric acid, and glyoxal.  The second resin can be a methylol-melamine-formaldehyde, methylol-urea-formaldehyde, or methylol-phenol-formaldehyde formulation.  When cured on a hydrophilic substrate, the fire-retardant composition becomes crosslinked and covalently bonded to molecules of the substrate.  Also, P-and N-containing constituents critical for fire retardancy are covalently bound in the thermoset, rendering these constituents non-leachable.  As a result, fire-retardancy is maintained throughout the useful life of the substrate, even when exposed to the weather.
