METHOD FOR PREPARING LEAD-ACID BATTERY PLATES Lead-acid battery plates are made by preparing alloys of lead with at least one additive metal that can be leached with an acid or an alkali from the alloy leaving a porous permeable lead matrix. The additive metal must be evenly and finely dispersed in the lead. A number of additive metals can be used but the additive metal is preferably magnesium or ...

This invention relates generally to a novel method of manufacturing a composite body. More particularly, the present invention relates to a method for modifying the resultant properties of a composite body, by, for example, minimizing the amount of porosity present in the composite body. Additives such as TaG, ZrC, ZrB2, VC, NbC, WC, W2B5 and/or MoO2B5 can be combined with a boron carbide material...

The specification discloses an impeller for cleaning devices. A plurality of impeller segments are slipped over a twisted flat wire to provide the impeller. Each of the impeller segments preferably includes a plurality of paddles, and a central section with a non-cylindrical opening for receiving said twisted flat wire.

A biochemically defined culture medium for culturing engineered Chinese hamster ovary (CHO) cell lines, which is essentially free from protein, lipid and carbohydrate isolated from an animal source, comprising water, an osmolality regulator, a buffer, an energy source, amino acids including L-glutamine, an inorganic or recombinant iron source, and a synthetic or recombinant growth factor, and opti...

A process for the preparation of the compound of formula (I) which comprises treating a compound of formula (V) wher- ein L is halogen or (a), wherein Ar is aryl, with a compound of the formula (VI): M-CN. A second aspect of the present invention is a novel intermediate of formula (V).; 2092997 9206968 PCTABS00012 A process for the preparation of the compound of formula (I) which comprises treati...

A call set-up technique which uses channel selection at both base (11) and subscriber terminal (13) in determining the radio traffic channel upon which to set-up a new call. Communication between the base station and subscriber terminal is carried out on a signalling channel until the traffic channel is chosen. Calls are set-up so that they proceed on the radio channel which, of a set of channels ...

A retroreflective marking material which can be secured to a substrate, e.g., a firefighter's helmet, and then readily removed, even after exposure to heat and flame, when desired. The marking material can contain fluorescent coloring agent(s) to afford good daylight visibility.

The invention relates to a CHO cell-line capable of producing antibody, the cell-line having been co-transfected with a vector capable of expressing the light chain of the antibody and a vector capable of expressing the heavy chain of the antibody wherein the vectors contain independently selectable markers; also included is a CHO cell-line capable of producing a human antibody or an altered antib...

A fishing rod has a tubular section (1) forming the butt/handgrip of the rod (2). This section has an external profile divided into two portions (3, 4) without any seam in between: the first portion is conically shaped so that it can be fixed inside the end of the successive tubular section (1); the second portion (4) is also conically shaped but tapers in the opposite direction to the first porti...

The antenna device comprises, on a substrate, a plurality of radiating elements and a pair of terminals for the supply of high-frequency electrical signals for each one of these elements. Each one of these radiating elements comprises a zone of spiral configuration (SPi), and possesses an extension (PB1i, PB2i) of the strands of its spiral having geometric characteristics different from those of s...

A purified preparation of an anti-CDW52 antibody which exhibits on size exclusion chromatography: a single peak under non-reducing conditions and two major peaks under reducing conditions. The preparation preferably also exhibits on conven- tional SDS PAGE: one main band using a non-reduced sample and two main bands using a reduced sample. Additionally the preparation exhibits on reversed phase H...
