Granted: 2000-08-08
Abstract: Stable aqueous fabric softening compositions based on water-dispersible cationic fabric softeners such as the di-long chain, di-should chain quaternary ammonium salts are provided using a combination of fatty alcohol and cationic water-soluble polymer to improve the rheological properties to enhance the softening performance. Both concentrated and ready-for-use formulations can be prepared. The active ingredients concentration in the concentrated formula is generally in the range of 11 to 20% by weight while for the ready-for-use formulations, concentration of the active ingredients may range from about 3 to about 8% by weight. In either case, the weight ratio of cationic softening agent to fatty alcohol may range from about 100:1 to about 1:1 and the ratio of cationic softener to cationic water-soluble polymer may range from about 100:1 to 1:1. These compositions have medium viscosity and are easily dispersible. Methods for making the compositions are also disclosed.

Title: Station selecting apparatus
Inventor: USUI AKIRA
IPC: H03J7/06
Filed: 1990-07-04
Granted: 2001-05-15
Abstract: A station selecting apparatus has a first mixer and a first local oscillation circuit for frequency converting the input signals (television signals) into a first intermediate frequency signal. A second mixer and a second local oscillation circuit convert the first intermediate frequency signal into a second intermediate frequency signal. A variable voltage device capable of varying a direct current fixed voltage in stages provides a signal for controlling the second local oscillator. The minimum potential width of the direct current voltage is set so that the frequency displacement (unit variation amount) of the second local oscillator obtained by the potential difference is smaller than the frequency resolution of the first local oscillator.

Title: Method and apparatus for preparing paper-containing and plastic-containing waste materials for component fraction separating
Inventor: PLACZEK TERRANCE M
IPC: B03B1/00
Filed: 1990-11-19
Granted: 1996-11-26
Abstract: This invention relates to an improved method and apparatus to effect the separation of component fractions from paper-containing and plastic-containing waste materials.  This method and apparatus accepts materials of widely varying  characteristics  such  as  paper, plastics, glass, metal, food wastes and other materials to be inserted en masse into a rotating vessel equipped with lifting paddles and directional flighting.  In this way the intimate contact of materials with moisture and heat is accomplished, thus effecting the repulping of paper materials.  The repulped materials, as a result of directional tumbling, are dispersed throughout the vessel.  Because   of   the   repulping of  the pulpable materials, size reduction of the randomly large and odd-shaped pulpable materials is accomplished.  By virtue of the size reduction of  the   large   and odd-shaped pulpable materials, the non-pulpable components are freed of the particle  shapes and  surfaces   that   affect separation.  The repulping of the pulpable materials increases the bulk density of  those  materials, further enhancing their   separation   from  the  additional components.  The recovered pulped product is suitable for recylcing into the paper industry; for combustion as a high quality fuel; or  for   use as a feedstock for conversion into chemicals.  The recovered non-pulpable material   such as plastics, glass, metals, aluminum and other materials are  suitable for recylcing into their producer industries; as feedstock raw materials for additional manufacturing of products; or any or all of these materials can be disposed of in a sanitary landfill as is the commonly accepted practice.

Abstract: A method of electrostatically spray-coating a workpiece with electrically-conductive paint subjected to a voltage using a spray gun, the spray gun having a rotatable atomizing head attached to a rotator for rotating the atomizing head.  A paint supply line supplies paint to the atomizing head and a cleaning line supplies cleaning liquid and air, where the air is under a pressure, to the atomizing head.  The rotator has a path for accommodating the paint supply line and the cleaning line therein, that path being formed in a cylindrical shape along a rotative axis of the rotator.  The cleaning line is disposed coaxially in the path with an end opening thereof disposed in the atomizing head.  The paint supply line is disposed coaxially within the cleaning line and has a nozzle tip thereof projecting frontward from the end opening of the cleaning line into the center of the atomizing head, preventing liquid communication between it and the cleaning line.  The method comprises the steps of: electrostatically spray-coating the workpiece with the paint; supplying the cleaning liquid to the atomizing head via the cleaning line to wash the atomizing head after spray-coating; supplying the air to the cleaning line after washing the atomizing head, to discharge the cleaning liquid remaining in the cleaning line through the atomizing head, at a delivery rate within a rate of spraying the paint during the spraycoating; and drying the cleaning line before spray-coating a next workpiece, to prevent voltage leakage, with air under pressure higher than an air pressure used for discharging the remaining cleaning liquid.
