Abstract: A purifier for an aquarium has a body being composed of an upper seat and a bottom seat. The upper seat has two tubular parts, two crowns respectively formed at upper ends of the tubular parts, two pipes respectively provided on the crowns and in communication with the tubular parts, and two plugs respectively provided in the crowns. The bottom seat has two rims formed at an upper surface thereof. The tubular parts are respectively secured in the rims. A pump seat is provided in the bottom seat. At least one air vent is defined through the pump seat. Two openings are defined through the bottom seat and respectively located in the rims and in communication with the pump seat. Two filtering means are respectively received in the tubular parts and communicated with the pipes. A pump is communicated with the openings.

Abstract: A cooling device for a hard disc. The cooling device is screwed to the hard disc by way of screw apertures provided on the bottom of the hard disc. The cooling device includes a housing, at least one cooling fan and at least one contact portion. The cooling fan is received in the housing. The contact portion is connected to the housing. The contact portion is in contact with the chip of the hard disc so that heat generated by the chip is absorbed by the contact portion and transmitted to the housing and then ventilated by the cooling fan.

Abstract: The present invention relates to compositions for treating shoes, especially leather-containing shoes, such as athletic shoes, and methods and articles of manufacture employing same to treat the shoes prior to and/or during and/or after washing the shoes. More particularly, the present invention relates to compositions applied to one or more shoes in need of treatment prior to and/or during and/or after washing the shoes for imparting a desired benefit to the shoes such as cleaning and/or conditioning and/or disinfecting and/or deodorizing.

Abstract: A process is described wherein a surface, for example the exterior surface of a vehicle, is contacted with a cleaning composition capable of rendering the surface treated hydrophilic and then rinsed with purified rinse water. Preferably the process also involves a pre-wetting step, wherein the surface is rinsed with water prior to being contacted with the cleaning composition, and/or an additional rinsing step, wherein the surface is rinsed with unpurified water prior to rinsing with the purified rinse water.

Abstract: The present invention relates to a spraying device suitable for spraying cleaning compositions and rinse water onto hard surfaces. More particularly the spraying device may be attached to a hose, for example a conventional garden hose, so that the cleaning composition and rinse water can be applied to outside surfaces, such as vehicles or the outside surface of windows. The spraying device comprises a purifier located inside the cavity of a container and a spray head.

Abstract: Detergent compositions containing certain acetals or ketals which hydrolyze upon exposure of surfaces washed in solution of said compositions to a reduction in pH, thereby releasing a fragrance which is characteristic of one or more of the hydrolysis products. The acetals and ketals themselves also form part of the invention; they have a molecular weight of at least about 350; a ClogP of about 4, and a half-life of less than 60 minutes when measured at pH=0 by the pro-fragrant hydrolysis test.

Abstract: A power supply includes a housing, a printed circuit board, at least one electrical element and a fan assembly. The housing has an interior and an exterior. The printed circuit board is provided in the interior of the housing, while the electrical element is attached onto the printed circuit board. The fan assembly is also provided in the interior of the housing. The fan assembly includes a shell and a fan. The shell includes two surface boards and plural side walls connected between the two surface boards. The interior and the exterior of the housing are communicated by a first hole formed on one of the two surface boards and at least one second hole formed on one of the plural side walls. The fan is mounted in the shell to ventilate the interior of the housing through the first hole and the second hole.

Abstract: An improved process for the manufacture of alkaline bleaching compositions, especially liquid and/or gel compositions of high solubility and low abrasiveness, useful to the consumer, especially as products for hard surface cleaning, bleaching or disinfectancy. The products are made by a three-stage process and comprise particular chlorine and bromine bleach sources and particular aminofunctional materials such as low-impurity sulfamate.

Abstract: Process for manufacturing bleaching compositions comprising halogen bleach, a source of bromine and an organic or inorganic derived --NH.sub.2 compound whereby improved bleaching performance is obtained and compositions obtainable by said process.

Abstract: A cooling device is provided for cooling at least one computer component device in a main frame. The cooling device comprises a case and at least one fan assembly. The case is mounted adjacent to the computer component device, and is provided with at least one first opening communicating with air outside the main frame and at least one second opening facing the computer component device. The fan assembly is mounted in the case to suck the air outside the main frame through the first opening and directly ventilate the computer component device through the second opening.
