PURPOSE:To prevent water from staying in a recessed upper wall of a timing belt cover. CONSTITUTION:In the case of a timing belt cover device whose timing belt cover gasket 20 is fitted to the rear end of a timing belt cover 18 having a recessed upper wall 18b, a notch 22 is provided in a timing belt cover gasket part corresponding to the lowest location of the timing belt cover upper wall 18b. Si...

PURPOSE:To manufacture a sealed lead-acid battery at a low cost by using a positive electrode lattice made of a lead-antimony alloy, filling and arranging the silica fine powder between a positive electrode plate and a negative electrode plate, and impregnating and holding a sulfuric acid electrolyte in the fine powder and the positive and negative electrode plates. CONSTITUTION:When a lead-antimo...

PURPOSE:To prevent peeling by forming a thin film made of lead or a lead alloy on a plastic film substrate, providing an active material layer on it, covering an active material layer with a porous plastic sheet, and sticking it to the substrate. CONSTITUTION:A thin film 2 made of lead or a lead alloy is formed on a plastic film substrate 1, and an active material layer 3 is formed on the thin fil...

In a method and device for filtering a suspension of particles in a liquid the liquid is passed continuously through a porous membrane, particles from the suspenion gradually accumulating on the membrane and clogging its pores. The filtered liquid is caused to flow momentarily in the reverse direction to return the accumulated particles to the suspension and so unclog the membrane. To achieve this...

This invention relates to a self-cleaning water filter which self washes in a counter-current of water operating by means of a turbine which rotates both a set of nozzles through which centrifuged jets of water flow and a set of brushes which scrape the external face of the filtering surface.

Water clarifying apparatus has a cylindrical tank where particulate contaminants suspended in raw water are separated using flotation techniques. A set of concentric mutually spaced, conical plates are positioned in the flotation tank. The plates rotate about the tank, preferably in unison with a (i) header that distributes equal quantities of raw water to each annular zone in the tank defined by ...

The furnace (70) includes a heating element (72) which is restrained from growth during operation of the furnace (70) by retaining spacers (84) which provide a yoke (88) around the individual coils (102) of the heating element (72) and which spacers (84) are interlocked with each other. A high alumina fiber insulation (180) is applied to insulate the heating element (72). This high alumina fiber i...

The invention relates to a coupling device which makes it possible to couple, by choice, one or two asymmetric lines to a same symmetric line so as, generally, to connect, by choice, one or two transmitters to a same antenna. The device uses symmetrisers (S1, S2) and switches (K1, K2) mounted in such a way that the simultaneous coupling of the two asymmetric lines (1-L2,2) to the same symmetric li...

Die Lamellenfeineinschnitte (17) in Profilelementen (14) der Lauffläche eines Reifens sind mit dreidimensional strukturierten Wandbereichen versehen, die sowohl in lateraler als auch in radialer Richtung Relativbewegungen gegenüberliegender Wandbereiche einschränken, um solcherart sowohl das Fahrverhalten als auch das Verschleißverhalten (Ausbrüche, unregelmäßiger Abrieb) derartiger Lamellenreifen...

The invention relates to a method and an apparatus for providing sanitary goods with attachment means for attaching to under-clothing. Elongated slits are formed at given intervals into a sort and elastic plastic foam sheet being the layer adjacent the underclothing; openings are formed by stretching the foam sheet at a given percentage so as to open the slits. The foam sheet is rolled and left fo...

A secondary battery has positive and negative electrode members (12, 13) juxtaposed on a substantially identical plane. End faces of the positive and negative electrode members (12, 13) oppose each other at a distance. A substrate (11a) fixes and supports the positive and negative electrode members (12, 13). A cover member (11b) defines, with the substrate (11a), a sealed chamber including the pos...

The utility model relates to a novel lead accumulator which can be charged or discharged with heavy current and has long service life. The utility model has the technical scheme that polar plates are provided with circular holes to prevent active substance particles from detaching and shucking off pole plate grids, the polar plates are enclosed by paper bags which prevent the active substance part...

The utility model relates to a lead accumulator which solves the problems that the existing industrial lead accumulator produces much acid fog when charged, the fluidounce loss is large when charged or discharged, and the structure, capacity, safety, etc. are not satisfied by users.
