Title: Wet-like cleaning articles
Inventor: ENRIGHT NANCY KIM
IPC: C11D17/04
Filed: 1998-07-20
Abstract: Disclosed are articles useful in cleansing, and particularly wet-like cleansing wipes and toilet tissue. These articles are essentially dry to the touch prior to use, but deliver liquid when subjected to in-use shear and compressive forces. In one aspect, the articles of the present invention comprise a carrier and an emulsion applied to the carrier, the emulsion comprising a continuous external nonpolar phase and an internal polar phase dispersed in the external nonpolar phase, wherein the article is capable of retaining fluid prior to use. In another aspect, the emulsion-treated articles exhibit improved ability to release fluid when subjected to in-use pressures. The articles of the present invention offer a number of significant advantages over prior cleaning products when in the form of wet-like cleansing wipes such as those used for cleaning of hardsurfaces (e.g., floors, countertops, sinks, bathtubs, toilets, and the like) and wet-like toilet tissue. The articles can in general be used in any applications requiring the delivery of polar materials, in particular water and water-soluble or dispersible actives.

Title: Vibration drive for a mold
Inventor: BRAUNGARDT RUDOLF
IPC: H02N2/00
Filed: 2000-04-17
Abstract: The vibration drive for a mold for producing concrete mold bodies consists of four piezoelectric vibration exciters which on the one hand are located in the four corner areas of a vibrating table of a molding machine and on the other hand are joined to the machine frame. In the conventional manner a vertically movable mold with several mold cavities which are open to the top and bottom is deposited on the vibrating table. After filling the mold cavities with concrete mass the vibration exciters are activated by applying a voltage and are caused to vibrate by shaking, these vibrations being transferred to the vibrating table and the mold. The vibration exciters are electrically connected to a microprocessor which for example controls the vibration frequency and other parameters of the vibration drive by corresponding, preselectable computer programs. The use of piezoelectric vibration exciters enables a vibration drive which can be easily and optimally adapted to various operating conditions in order to thus improve the quality of the final product.

Abstract: A dirt cup latching mechanism that secures a lid onto a dirt receptacle of vacuum cleaner and simultaneously secures the dirt cup in place on the vacuum cleaner. The latching mechanism presses the lid down onto an open top of the dirt receptacle and presses the dirt receptacle down into a dirt cup retaining recess provided in a generally horizontal wall of the vacuum cleaner housing. The latching mechanism may press down on the top of an open topped dirt receptacle, with or without a lid, while simultaneously pulling the dirt cup horizontally against a generally vertical wall of the vacuum cleaner housing. Thus, the latching mechanism simultaneously presses the dirt receptacle down against one of an inlet and outlet seal located on the horizontal wall of the housing and horizontally against the other one of inlet and outlet seal on the vertical wall of the housing, thereby sealing both the receptacle inlet and outlet.

Abstract: An improved wing-type ground anchor. The ground anchor includes a central body portion, wings radiating laterally from the body portion, and a leg portion at the front end of the body portion GROUND ANCHOR that operates like a star-point drill for penetrating the ground. The sides of the leg portion each include a plurality of sharpened leading side edges which are longitudinally offset from each other. Each of the wings also includes a plurality of sharpened leading side edges which are longitudinally offset with respect to each other.  The offset leading side edges and wing edges progressively extend greater distances laterally outward from the body portion along the length of the leg portion and the wings. Since smaller side edges and wing edges are advanced first, the staged side and wing edges facilitate passage of the ground anchor through soil. The wings of the ground anchor also diminish in thickness and taper between the leading and trailing edges for reducing friction between the top and bottom wing surfaces and the soil. In combination, the staged side edges, staged wing edges, and tapered wings greatly reduce the driving force required to drive the ground anchor through the ground. The ground anchor also includes an elongated slot for connection to a pull member to reduce impact forces between the pull member and ground anchor by allowing them to move freely with respect to each other as they plow through the ground. The bottom of the ground anchor is also provided with first and second curved lip portions which project outwardly from the body portion for facilitating tilting of the ground anchor within the ground.

Filed: 1999-04-27
Abstract: On introduit une fibre extrêmement résistante possédant un module d'élasticité élevé dans l'adhésif non durci de la ligne de collage d'une poutre de bois laminaire, ce qui améliore la résistance de la poutre à l'affaissement, à la déformation plastique et au cisaillement, tout en augmentant les caractéristiques de remplissage des espaces de l'adhésif. Dans un mode de réalisation, on applique uniformément des fibres discontinues au-dessus de l'adhésif en raison d'approximativement 0,25 à 1,35 % en poids de fibre. Ces fibres consistent en des fibres coupées d'aramide, de carbone, de verre ou en d'autres types de fibres possédant une résistance et un module d'élasticité importants et on les applique en longueurs de 0,025 à 2,54 centimètres. Dans un autre mode de réalisation, on utilise des fibres discontinues en tant qu'additif à une matrice de résine pour des produits reconstitués à base de fibres afin de limiter les modifications dimensionnelles. Dans un troisième mode de réalisation, on utilise des fibres continues dans la ligne de collage avec une tension préalable ou sans tension afin d'améliorer la résistance au cisaillement et à la déformation plastique, ainsi que la robustesse de la poutre.
