The apparatus (10) also includes a quality control systems, including a conductivity cell (50), a weight measurement station (26), and a volume flow measurement device. The apparatus (10) also includes an electronic control unit (70) associated with the pumps (43) and valves (41) to operate them in response to a pre-selected volume, sequential combination and concentration of chemicals.

Static air freshener device and cartridge

Abstract: An air freshener device (10) is disclosed. The air freshener device (10) includes a cartridge (12) having a housing (16). The housing (16) has a sealed first cavity (26) and a sealed second cavity (28). First fragrance (60) is located within the first cavity (26) and has a first volatility. Second fragrance (62) is located within the second cavity (28) and has a second volatility. First and second cavities (26) and (28) have first and second openings (64) and (66) respectively. First opening (64) is covered by a first removable cover (68) and second opening (66) is covered by a second removable cover (69). Alternatively, a single cover may be used for both openings. When the covers (68) and (69) are removed the fragrances (60) and (62) independently exit their respective cavities (26) and (28). The device (10) includes an outer housing (14) having a front member (70) which includes air passage openings (72). The outer housing (14) has a back member (74) adapted and configured to be mounted on a surface. Top member (78) and bottom member (80) connect front (70) to back (74). Top and bottom members (78) and (80) have openings (82) and (84) which define a slot (86) extending the length of the outer housing (14). The slot (86) is sized and configured to receive the cartridge (12) whereby when the cartridge (12) is expired a second cartridge (98) is inserted into the slot (86) proximate the top member (78) and the second cartridge (98) is moved in the slot (86) toward the bottom member (80), the cartridge (12) moves downward in the slot (86) and is forced out the bottom member (80) by movement of the second cartridge (98). The air passage openings (72) receive air which moves over the cartridge (12) picking up the fragrances (60) and (62) resulting in an air-fragrance mixture which exits the air passage openings (72) thereby allowing dispersion of the fragrances (60) and (62).

Dishwashing apparatus including a flip-flop solid detergent dispenser

Abstract: A flip-top detergent dispenser (30) comprising a base means (31) having a funnel-shaped interior, a nozzle (22) positioned within the interior of the base means, and a detergent container support (32) connected by a hinge (33) to the base (31). The detergent container support (32) is designed to hold only a particular shaped detergent container (23), thus helping to insure that only suitable detergent products are used in the warewashing apparatus. The flip-top detergent dispensed (30), mounted on top of the dishwashing apparatus (1), is designed so that the detergent container (23) can be inserted into and removed from the detergent holder support (32) only in an upright position to prevent dripping of detergent sulution on to the user. Water will not spray up through the product nozzle (22) unless particularly shaped detergent container (23) is situated in the detergent support holder (32) and the detergent support holder (32) is closed. Preferably, the detergent support holder (32) has open areas so that labels including instructions and warnings can be read on the solid detergent container (23). A circular metallic ring (37) having a plurality of holes is situated around the funnel-shaped interior of the base (31). Water is flushed through the holes of the circular metallic ring (37) at designated times to insure that the detergent is rinsed down through the funnel-shaped interior of the base.

Compositions and methods to vary color density.

Abstract: Aqueous processes and compositions of the invention for obtaining a 'stone-washed', distressed or 'used and abused' look in clothing, particularly in the panels and seams of denim jeans and jackets involve compositions that are stone-free that avoid mechanical abrasion of the fabric. In particular, the process and composition of the invention used to obtain the distressed, 'stone-washed' or 'acid washed look' are free of common pumice or pumice-bleach compositions, used in large institutional-size laundry machines, and rely solely on the chemical action of aqueous treatment compositions. The aqueous treatments can be made from liquid or solid concentrates.

Cast detersive systems

Abstract: A general purpose detersive system and detersive system useful in warewashing and in laundry processes have been developed in which highly active encapsulated halogen sources have been incorporated into cast, solid detersive systems containing oxidizable organics that are highly reactive with the active chlorine sources. The stability of the detersive systems thus formulated has been shown to be sufficient to permit the cast materials to be storage stable for a sufficient period to permit the manufacture, distribution, sale and consumption of the cast materials before the availability of either the organic materials or the active halogen drops below an effective level.
