Abstract: An arrangement for detecting toilet flushing by utilizing an acoustically-based motion detector in a simple amplifier circuit. The detector is in contact with the toilet bowl, which acts as a resonant system. Upon detection of such flushing, a subsequent event, such as a cleaning or disinfecting a toilet, ventilating the surrounding area or releasing deodorant into the area, may be triggered. The mechanically resonant system with the provided circuit is capable of separating frequencies from the frequency of the flushing water in a specific bowl design and provides a high degree of immunity to unwanted ambient frequencies. In addition, the system consumes low power and is suitable for battery power operation.

Abstract: Disclosed are aqueous, acidic hard surface cleaning compositions particularly effective in the removal of greasy stains and soapscum from hard surfaces. The compositions have a pH of not more than 2, preferably not more than 1, comprising: one or more anionic surfactants; a nonioinic surfactant constituent which preferably comprises both a first alcohol ethoxylate nonionic surfactant derived from monobranched alkoxylated C10-fatty alcohols and/or C11-fatty alcohols and about a second alcohol ethoxylate nonionic surfactant, preferably a C10-C14 linear alcohol ethoxylated surfactant having at least about 8 mols ethoxylation, an organic solvent constituent, which preferably comprises or consists of a phenyl containing glycol ether solvent, an acid constituent, which most preferably comprises, or consists of, a ternary acid system comprising each of: sulfamic acid, formic acid and oxalic acid in a respective weight ratio of sulfamic acid:formic acid:oxalic acid of 1-8:1-5:1-3.

Abstract: This invention relates to a dosage element of cleaning composition and an associated chamber for use in a ware washing machine, for example a dishwashing machine or a laundry washing machine. The dosage element and chamber are particularly useful in the context of forming part of a multi-dosing detergent delivery device and/or a refill for such a device. The element supports various different configurations of ingress and egress holes for an efficient dissolution of cleaning composition.

Abstract: Improved treatment blocks useful in the treatment of lavatory appliances, particularly toilets are provided. The improved treatment blocks are solid block compositions which comprise at least one detersive surfactant, a film forming constituent, optionally a bleach constituent and one or more further optional constituents. The improved treatment blocks provide good detersive characteristics and further provide a film forming material which contacts the surfaces of the lavatory appliance, e.g., toilet, in which the block compositions are used. Methods of producing the solid block composition and treatment blocks therefrom, as well as methods of use are also disclosed.

Abstract: Disclosed are devices for the treatment of a lavatory appliance which device generates a mist of a treatment composition, viz, an aerosolized treatment composition which imparts a technical benefit to surfaces of the lavatory appliance which come into contact with the said aerosolized treatment composition. Methods for use of the devices for providing a technical benefit to surfaces of a lavatory appliance treated with the treatment composition, or airspace in the ambient environment of the lavatory appliance are also disclosed.

Abstract: A liquid detergent composition has a thickening system which comprises; (a) a carboxylic acid/carboxylate polymer, and (b) a polymer comprising an ammonium group.

Abstract: The present invention provides compositions which not only effectively kill a broad spectrum of microorganisms present on surfaces on contact but continue to kill microorganisms for a period of time thereafter.

Abstract: A spraying device (10) is described, the device comprising a housing (12) adapted to receive a refill (16) of fluid therein and having an aperture (14) suitable for permitting, in use, the spraying of a fluid therethrough, the device further comprising actuation means (24) configured for periodic actuation of the refill, wherein the device is provided with detection means (26) configured to distinguish between at least one area of lower reflectance and at least one area of relatively higher reflectance on a spray head of said refill. Methods of operation of such a spraying device are also described.

Abstract: A method of forming an essentially tubular blowable plastics parison comprises injection moulding an essentially tubular parison around a mould surface. Means for injecting flowable plastics material to said injection mould at an injection station to form a parison within said mould surface are used. These comprise a plurality of individual injectors, with at least a secondary injector being capable of injecting a different composition from the remaining primary injectors.

Abstract: A cleaning article comprising a melamine foam which comprises a cleaning fluid. Also disclosed a methods for the manufacture of said cleaning articles, and methods for their use in the treatment of hard surfaces.

Abstract: An article comprises a rack of solid sticks (12) of dishwasher detergent, retained on a backing material (16) and being formable into a nested, preferably cylindrical, form. The nested article is inserted into a holder, which is a plastics body, rigid and substantial. The holder is a permanent article located in use in a dishwasher but the article is a refill. Wastage of material when it is exhausted is minimal.

Abstract: An outlet head (22) for a spray device (10), the outlet head (22) comprising an inlet section (31) having an opening (30) adapted to receive an output section (20) of a spray material container (16), said opening (30) forming a first end of a fluid channel for spray material from the spray material container (16), the outlet head (22) also comprising an outlet portion (14) adapted to eject spray material and forming a second end of the fluid channel for spray material, wherein the inlet section (31) has a first, major, lateral axis and a second, minor, lateral axis, said first and second axes being substantially at right angles to one another, wherein the size of the inlet section along the first, major, axis is greater than the size of the inlet section along the second, minor, axis.
