Publication number: 20040216500Abstract: Disclosed are systems, methods, devices and kits for the timed dispensing of laundry additive materials into the drum during a cycle of a multiple cycle fabric laundering operation. To bring about such dispensing of additives, a housing structure device having multiple chambers is placed within the drum of an automatic washing machine, a unit dose insert package, containing laundry additives in at least one compartment of the insert, is placed within the housing structure, and the machine is run through the several stages of its laundering cycle. A piercing element is provided to open the compartment of the insert in the laundering cycle to dispense contents of this compartment into the washing machine drum as rinse additive materials. The contents move from the insert to the first chamber of the housing structure device by centrifugal force arising during the first spin cycle of the laundering operation. The centrifugal force also holds the contents within the first chamber until cessation of the spin cycle.Type: ApplicationFiled: February 12, 2004Publication date: November 4, 2004Applicant: The Procter & Gamble CompanyInventor: Yousef Georges Aouad

Publication number: 20040216499Abstract: A laundry washing machine comprises a dispenser of washing agents (10) having at least a movable body (26A, 26B, 40) defining a compartment for containing a dose of a respective washing agent. The movable body (26A, 26B, 40) is mounted in a housing (11) in such a way as to be able to assume a first position, for the manual admission of a washing agent into the compartment through a loading mouth (27, 41), and a second position, for withdrawing the washing agent from the compartment by means of a flow of liquid (IN). The movable body (26A, 26B, 40) is pivotally supported in the respective housing (11) to move angularly from said first to said second position and vice versa, around an axis (X) that is substantially perpendicular or otherwise transverse relative to the axis (Y) of the loading mouth (27, 41) of the body (10). Preferably, the movement of the body (26A, 26B, 40) from the first to the second position is obtained by means of the aforesaid flow of liquid (IN).Type: ApplicationFiled: February 3, 2004Publication date: November 4, 2004Applicant: MERLONI ELETTRODOMESTICI S.p.A.Inventor: Dino Bongini

Publication number: 20040205899Abstract: A washing machine and method of controlling the same. The washing machine has:a disinfecting liquid dispenser, a drive unit, a comparator unit and a control unit. The disinfecting liquid dispenser provides a disinfecting liquid to disinfect laundry. The drive unit generates first and second control voltages and outputs the first and second control voltages to the disinfecting liquid dispenser, to control a concentration of the disinfecting liquid. The comparator unit determines whether the concentration of the disinfecting liquid falls within a predetermined range. And the control unit controls the drive unit so that the concentration of the disinfecting liquid has a value within the predetermined range.Type: ApplicationFiled: December 23, 2003Publication date: October 21, 2004Applicant: Samsung Electronics Co., Ltd.Inventors: Seon-Woo Park, Young-Hyun Kim

Patent number: 6796151Abstract: A method and a device for dyeing a textile substrate in at least one supercritical fluid, are described, whereby the textile substrate is arranged in an autoclave, where at least one supercritical fluid loaded with a dyestuff flows over and/or through the textile substrate, and the at least one powdered dyestuff is brought in contact with the supercritical fluid, forming a stable solution and/or dispersion of the dyestuff in the supercritical fluid. The quantity of dyestuff required for dyeing is divided into a plurality of dyestuff partial quantities, and each partial quantity of dyestuff is separately brought in contact with the supercritical fluid until this partial quantity of dyestuff is dissolved or dispersed. Hereafter the next partial quantity of dyestuff is introduced into the supercritical fluid, and this process is repeated several times until the total quantity of dyestuff has been introduced into the supercritical fluid.Type: GrantFiled: June 22, 2000Date of Patent: September 28, 2004Assignee: Amann & Soehne GmbH & Co.Inventors: Rudolf Eggers, Kurt Truckenmuller

Patent number: 6792637Abstract: An apparatus dispenses detergent into a warewasher from a reservoir wherein a flow control device controls the flow of the detergent. A sensor measures the electrical conductivity of water within the warewasher and produces a conductivity measurement. A controller operates the flow control device in a first mode in which the quantity of detergent dispensed into the warewasher is determined in response to the electrical conductivity of the water. If the conductivity measurement is determined to be unreliable, the controller operates in a second mode in which a predefined quantity of detergent is dispensed into the warewasher. The reliability of the conductivity measurement is determined based on the amount that the conductivity changes upon detergent being added to the warewasher.Type: GrantFiled: January 8, 2002Date of Patent: September 21, 2004Assignee: U.S. Chemical CorporationInventors: Kurt A.

Patent number: 6792776Abstract: A high efficiency water valve member for a washing appliance includes a hot water valve, a cold water valve, and a low cold water valve. Associated with the hot water valve, the cold water valve, and the low cold water valve are a hot prime mover, a cold prime mover, and a low cold prime mover. These prime movers move their respective valves between their open and closed positions. When filling for a hot wash the hot prime mover and the low cold prime mover are energized to open the hot water valve and the low cold water valve. The cold water valve remains closed. For warm washes all three solenoids are activated to open all three valves. For cold washes the cold prime mover and the low cold prime mover are energized either together or alone to open either or both of the cold water valve and the low cold water valve.Type: GrantFiled: October 26, 2001Date of Patent: September 21, 2004Assignee: Maytag CorporationInventors: Jordan S.
