Batteries based on lead chemistry, e.g., lead-acid batteries, are substantially improved through the use of a particular positive material. This material is formed by the electrochemical conversion of tetrabasic lead sulfate (TTB) where this TTB is synthesized at a pH in the range 9.3 to 12 and under reaction conditions that provide a substantial excess of sulfate to the reactive lead. The resulti...

A method and apparatus for reducing the magnitude of a uniformity characteristic in a cured tire and the tire produced thereby. A signal is generated which is indicative of the magnitude of the uniformity characteristic. The signal is also indicative of the location on the tire to be corrected. At least a portion of one carcass reinforcing member of the tire is permanently deformed a predetermined...

An exercise apparatus has a base having a concave recess in its top surface adapted to receive a resilient ball and at least one attachment point for removably attaching an elastic band. The elastic band has a handhold attached to its end that can be grasped by a user to perform a desired exercise regimen.

A receptacle (1) is mounted on a pole (6) by gripping, with a worm drive circumferential clip (5) the fingers (4) of a locating tube (2) against fingers (9) of at least one inner sleeve (7) which is removably mounted within the locating tube. The inner sleeve (7) can be removed to enable the receptacle to be mounted on a pole of larger diameter.

A thermoplastic interlayer, such as of polyvinyl butyral, has a regular pattern of deairing channels formed in each side which are angularly arranged with respect to each other wherein, to avoid moire, the angle of intersection is at least 25 degrees, preferably 90 degrees.

A stretched resin film having as a base material a resin composition composed of the following components (A), (B), (C) and (D): (A) a thermoplastic polyester resin 100 parts by weight; (B) a modified olefin based resin obtained by graft polymerizing 0.01 to 20 parts by weight of an alpha , beta -unsaturated carboxylate based monomer having a hydroxyl group and 0.01 to 50 parts by weight ...

An improved process is provided for the preparation of siloxane-oxyalkylene and siloxane-alkyl copolymer compositions via a hydrosilation reaction in the presence of high boiling point natural vegetable oils as the reaction solvent. The reaction solvent need not be removed from the block copolymer product, and indeed is beneficial to remain with the copolymer particularly when the copolymer is use...

Described is an NCO-group-containing polyurethane prepolymer madefrom polyisocanyates and polyols derived from natural oils. The invention is characterized in that the polyol is obtained by transesterification in the presence of basic lithium compounds. Together with a tertiary amine used to accelerate the moisture curing, the storage stability is thus increased considerably. Up to 4.0 mmol of the...

Production of a half reinforcement of a tyre carcass from a single strand (23) round a bead wire (8) consists of: (a) holding the bead wire in a predetermined position; (b) positioning a ring (14) a predetermined distance from the wire and approximately coaxial, with the planes of the two being parallel, the ring having half the number of hooks (15) as the number of strand loops contained in the r...

Radial ply tyre carcass has two half-reinforcements anchored in the beads containing at least one bead wire (1) to which they are connected. Each half-reinforcement is made from a single strand (2) that goes around the beadwire and forms adjacent lengths (20, 21, 22) extending from the beadwire to at least the means of joining the two halves, the two adjacent lengths of each group passing axially ...

Die Erfindung betrifft Verfahren zur Herstellung von thermoplastischen Polyurethanen durch Umsetzung von (a) Isocyanaten mit (b) gegenüber Isocyanaten reaktiven Verbindungen, gegebenenfalls in Gegenwart von (c) Kettenverlängerungsmitteln, (d) Katalysatoren und (e) üblichen Hilfs- und Zusatzstoffen, dadurch gekennzeichnet, daß man dem Reaktionsgemisch vor, während und/oder nach der Umsetzung vernet...

A diamond film of this invention is formed from growth nuclei distributed on a substrate at a density of at least 1x10<10> numbers/cm<2>, the film is dense, having flat surface and great freedom in the thickness of the continuous film. The growth nuclei can be distributed at such a high density by, for example, dispersing diamond grains of average diameter of no more than 0.1 mu m in an acid solu...
