Abstract: An abrasive structure for stone washing garments in a wash medium and a method for abrading garments using that abrasive structure to achieve controlled abrasion of those garments are disclosed. The abrasive structure has a uniform abrasive surface which will not damage or excessively wear fabrics and garments being subjected to the stone washing method, which will not deteriorate during use, and which will provide uniformly stone washed garments having a consistent nap and a low level amount of textile wear. The abrasive structure is formed of a substantially form-retaining material having a resilient abrasive surface. For example, the abrasive structure may be formed of a block of form-retaining material substantially impervious to aqueous washing systems and a resilient layer of synthetic abrasive material substantially surrounding the block and affixed to the exterior surfaces of the block.

Abstract: A method and apparatus for supplying dyes to a dyeing apparatus, dyes being selected to yield one of a group of colors. A plurality of tanks of dye is provided, and a circuit leads from each tank to a selected one of a pair of valves that may either direct the dye to the dyeing apparatus or direct the dye to be recirculated. The flow through each valve is metered so a particular rate of flow can be established. One group of the valves provides dye to the dyeing apparatus while another group of the valves recirculates dye to establish another color ready to be provided to the dyeing apparatus. The colors are defined in terms of the tanks and rate of flow from the tanks, so a large group of colors can be defined and stored in a computer, and the computer can control valve position and pump speed to control the color produced by the dyeing apparatus.

Abstract: When both colored and white wash are to be laundered together, one has the problem that pigment particles are transported from the colored pieces to the white pieces and the white pieces are discolored. This problem will be eliminated in a novel counterflow cycling washing machine by providing additional components besides the control components for the counterflow which produce a reversal of the usual counterflow to concurrent flow when a colored piece of wash is in the machine or the washing zone. For the case of concurrent flow operation the counterflow pump is shut off and the counterflow discharge outlet valve and the counterflow input tube valve are closed, while the valve in the concurrent flow discharge outlet positioned near the counterflow input tube and the valve in the concurrent flow input tube positioned near the counterflow discharge outlet are opened.

Each array dispenses streams of foamed dyestuff over a gum coated web in alternate groups of first and second colors, the second array dispensing its dyestuff superimposed over the dyestuff dispensed by the first array. The same dyestuff color groups overlap in spaced repeating regions of the carpet web while different colors overlap in the remaining regions to provide a fully dyed web having the appearance of repetitive spaced regions of either the first or the second colors.

Abstract: The present invention relates to a method and apparatus for cleaning upholstery which involves minimal risk of dye bleeding and which is reasonably effective. The invention uses a hand-held applicator and a remote unit. A jet nozzle on the hand-held applicator sprays cleaning solution onto the upholstery.

If such a value surpassing the permissible out-of-balance force was measured as a value disposed below the set value, then the acceleration to the final rotary spinning speed is turned on.

Abstract: Automatically operating washing machines adjust the washing time, the wash water temperature and the motion, i.e. agitation, of the laundry based on predetermined cycles, such as wash, spin, or rinse, etc. An adjustable program course controls these cycles. Naturally, certain cycles require hotter or colder temperatures than others. The method of the invention varies the program course to cycles requiring hotter or colder temperature, depending on the temperature available. Therefore, if a cycle requires hot water but only cold water is available, another cycle will be chosen or the cycle will run for a shorter time. The automatically operating washing machine has at least one cold water inlet and at least one warm water inlet.

Preferably, a secondary settlement tank immediately below and directly communicating with the main tank is provided and the discharge outlet, controlled by a suitable valve, is at the base of the secondary tank. The secondary tank has a zone offset from the main solid flow in which the sensor may be located in order that large aggregates of solids do not lead to spurious operation of the sensor.

Abstract: Dye for coloring a carpet is applied to a manifold and then passed through a plurality of nozzles to a plate. The dye floods across the plate and then falls off the edge of the plate in a waterfall-like pattern to a carpet being carried below the plate. This provides for a coloring of the carpet with the dye. The improvement herein is in the recirculation of the dye in the manifold to maintain the particles in the dye in suspension, and further, to interrupt the flow of dye from the nozzles to the plate to better distribute dye particles on the plate for subsequent distribution to the carpet.

Abstract: In a clothes washer, liquid pulses are delivered to a bucket or tank of water to create continuously re-circulating flow therein in a vertical plane. The flow carries the clothes in a tumbling action and the pulses agitate the clothes passing the pulse source. Air is introduced into the water pulses and forms air bubbles in the tank which attract dirt particles and carry them to the surface where they are removed as part of a continuous surface overflow. In a preferred embodiment the liquid pulses are delivered by a novel fluidic oscillator of the feedback type in which air is continuously entrained by the power stream from each feedback passage in alternation.
