Title: Apparatus and method for controlling the introduction of chemical foamant into a water stream in fire-fighting equipment
Inventor: ARVIDSON LAWRENCE C
IPC: H02P7/29
Filed: 1994-02-09
Granted: 1996-11-12
Abstract: A fire-fighting system in which a liquid chemical foamant is introduced into the water stream in varying amounts so as to maintain  a  predetermined  percentage  mixture  irrespective  of variations in the water flow includes a motor-driven pump where the motor  is  controlled over a first  speed range by pulse width modulating the drive to the motor and over a second speed range, producing intermittent motion, by burst width modulating the drive signal when it is operating at its minimum pulse width modulated duty cycle.   Using this technique the range of available motor speeds is extended well beyond that which can be achieved using pulse width modulation of the motor drive signal alone.

Abstract: When printing images as ordinary prints on a photosensitive material, index prints are also automatically printed of a same size as the ordinary prints for higher work efficiency.  At a projection exposure stage, exposure of a film is effected to obtain ordinary prints using a light source, a lens and a shutter.  Also data of images on the film is read by an optical reader and converted into digital signals.  Index prints are then exposed by a PLZT print head which is controlled based on the digital signals.

Abstract: A reusable container closure which telescopes over the open top or bottom of the container is formed by utilizing a one-piece paperboard blank which is cut, scored, and folded to present a central panel, and at least three side panels depending from the central panel. A first side panel has a corner flap. A second side panel has a notch. The first side panel and the second side panel meet to form a corner. The corner flap is folded about the corner to lie against the second side panel. The corner flap also has a friction stop folded to engage the notch, which extends through the notch. When the container closure is telescoped over the container, the container urges the friction stops towards the second side panel so that the container closure embraces the top of the container. When the container closure is later removed from the container, the friction stop is simply disengaged from the notch and the container closure may be flattened and returned for re-use.

Title: Thermochromic ink formulations, nail lacquer and methods of use
Inventor: SMALL LYLE D
IPC: C09D11/00
Filed: 1995-09-29
Granted: 2002-07-02
Abstract: The present invention comprises a series of discoveries related to the problems associated with formulations that destroy the color change properti es of thermochromic encapsulated dyes. One aspect of the present invention is t he discovery of a method of correcting these formulations to allow the addition  of thermochromic dyes. Certain solvents destroy the dye, therefore any aldehydes, ketones, and diols, and most aromatic compounds should be removed  from the formulation and if needed they should be replaced with solvents preferably having a large molecular weight (i.e. greater than 100 and low reactivity). Secondly, the formulation should be adjusted to be neutral (i.e . 6.5-7.5 pH) or have a low acid value. These two adjustments will allow the thermochromic dyes to be added to the formulation without a loss of its colo r change properties.
