Abstract: A fluid delivery powered toothbrush utilizes a removable/disposable neck assembly that contains a fluid reservoir, a fluid delivery system and a fluid path therein leading to a brush receptacle. No fluid is used in or passes through the toothbrush handle. Preferably a pump is located in the neck assembly and activated at the same time as the brush drive such that fluid is delivered during brushing. In one embodiment of the invention, the brush is replaced with a nozzle for providing fluid prior to or after brushing. The components for the neck assembly are disposable to minimize cross-contamination while enhancing fluid delivery to the teeth during brushing.

Abstract: A device for cleaning and improving the hygiene of the oral cavity and in particular of the tongue, comprises a rod 1 having a flat head 2 fixed to one end thereof. The head has two opposite flat surfaces 2a, each surface having a plurality of protuberances 3 thereon designed for scraping and brushing the upper tongue surface during cleaning. A fluid tank 8 can be located inside the rod 1, the fluid flowing through a channel 5 toward exit holes 6 made on the surfaces 2a of the head 2, or a cartridge can be attached at an end of the channel outside the rod. In each instance, fluid such as mouthwash is applied during cleaning.

Abstract: The invention relates to an otter board (20) which may be used for generating a spreading force in connection with trawl fishing. The otter board according to the invention comprises at least two foils (1-3) which are suspended between a number of longitudinally extending ribs (5, 6, 10, 17, 26, 27) in such a way that at least one tapered channel is formed in which the flow of water is passing through the otter board. The channels are curved and formed so that water is ejected at a high speed in relation to the towing speed in a direction slightly downwards and along a respective end section of an adjacent lower or intermediate foil extending from the outlets of the channels, whereby turbulence is prevented from occurring even at high angles of attack of the otter board.

Abstract: A method is provided for compensating an output signal of an electronic device having an input end electrically connected to a feedback device and an output end electrically connected to a load. This method includes steps of (a) measuring a standard voltage V.sub.o of the load, (b) determining an input voltage V.sub.i and an input current I.sub.i of the electronic device, and (c) generating a feedback signal based on said input voltage V.sub.i. The method further includes steps of (d) determining a maximum current I.sub.max and a minimum current I.sub.min of the feedback signal passing through the feedback device, (e) defining an estimated output current I.sub.o of the electronic device based on the maximum current I.sub.max and the minimum current I.sub.min, and (f) compensating the output signal of the electronic device according to a compensating factor d determined by the standard voltage V.sub.o, the input voltage V.sub.i, the input current I.sub.i, and the estimated output current I.sub.

Abstract: A covering band (12) is pre-heated and then definitively heated in two subsequent areas (P,Z), and is subjected to primary pulling, in an area (T), where the covering band is pulled and applied to a blister band (1), and to secondary pulling in an area (R) which coincides with the pre-heating area (P). The speed of the covering band (12) is lower in the secondary pulling area (R), so as to determine a lengthening which corresponds at least to its maximum lengthening resulting from pre-heating. Cyclical detecting of reference marks (20) printed on the covering band determines temporary reducing of the covering band (12) speed in the secondary pulling point (R), so as to provoke an additional lengthening. The device includes pulling means (5,11) of the blister band (1) and covering band (12), pre-heating means (11) and heating means (13) for the covering band (12), detecting means (16), and driving means (30) acting with different speeds, controlled by the detecting means (16).

Abstract: To stimulate and engage children, especially older children, playground equipment is disclosed which provides a suitable challenge, by consisting of three columns which are arranged in a triangular cross-sectional form which tapers inwardly. The columns are assembled with connection tubes at the top and possibly also further down to provide a stable and very strong construction which supports various accessories elements such as ropes, climbing walls, cross-beams, etc. A spherical assembly bracket with through holes is mounted on a column and used in the assembly and suspension of the accessory elements.

Abstract: A preform suitable for use in a resin transfer molding process comprising (1) one or more layers of a non-woven random mat and (2) one or more layers of a series of tows of unidirectional fibers held together by a polymeric curable resin film grid. The polymeric resin film is in the form of a grid, such that only a fraction of the surface area of the fibers contacts the resin film.

Abstract: The improved apparatus for processing a photosensitive medium comprises a tank 1, having a substantially semi-cylindrical shape and provided with an input opening 1a and output opening 1b.A transporting means 50 is provided above the tank 1, consisting of a pair of input rollers 51, a pair of output rollers 52 and a conveyor 53, fit to route a sheet 2 from the output opening 1b to the input opening 1a.There are also provided an input guide 41 and an output guide 42, fit to guide the sheet 2 along a closed loop including the tank 1, or to the apparatus exit door.
