PURPOSE:To perform an easy and high-precise molding of a level surface at an end surface of an upper mold clamp of a level surface at an end surface of an upper mold clamp for a bladder, by a method wherein, after the level surface is formed at the end surface of the upper mold clamp part of the bladder of vulcanization-molding, an attaching aperture is bored in the end surface. CONSTITUTION:A bla...

PURPOSE:To increase thrust and durability by forming a contacting surface between a fixed pulley and a movable pulley in such a manner that the coefficient of friction of the small-diameter side portion is larger than that of the large-diameter side portion, and forming the large-diameter side portion by material with good thermal conductivity. CONSTITUTION:A fixed pulley 2 is fixed to an input sh...

PURPOSE:To reduce the internal resistance of a lead storage battery so as to improve its discharge characteristic by using a grid made of a copper material completely coated with a lead material for a negative plate and adjusting the capacity of the negative plate to be greater than that of a positive plate. CONSTITUTION:A negative plate is made by using a grid consisting of a copper or copper all...

The sliver guide is comprised of a cylindrical sleeve rotatably mounted on an inner element fixed to the guide table. The sleeve carries a radial outwardly projecting flange above the table in order to support the combed sliver such that the moving sliver rotates the sleeve so that sliding friction does not occur between the guide and the combed sliver. The inner element is adjustably mounted by a...

Friction rolls for working elongate members, e.g., webs or strands, such as crimper rolls, draw rolls, yarn package drive rolls comprising a roll having a generally cylindrical external surface and a ceramic, e.g., alumina, mixtures of alumina and titania, chromia, zirconia, or metallic carbide, e.g., tungsten carbide, coating bonded to the external surface, said coating being laser-engraved, that...

A polymer composition comprises : component a) which is at least one aromatic polysulphone, containing the repeating units - Ph - SO2 - Ph - Ph - SO2 - Ph - I and - Ar - II (where Ph is phenylene and Ar is a divalent aromatic radical) linked together through ether linkages, in a relative molar proportion of the units I : II in the range 25 : 75 to 60 : 40; and component b) which is 5 to 80% b...

A document shredder (11) has a cutting mechanism (13), which is driven via a gear (25) by an electric motor (26). In the return movement a diode (30) is connected in, which reduces the voltage supplied to the motor and therefore its maximum torque. This avoids material being jammed on the top of the cutting mechanism during the return movement in such a way that the cutting mechanism cannot be rot...

In a process for making a bobbin having a desired bobbin diameter by winding a roving (4) or the like onto a tube (2), especially by means of a flyer (7) and a press finger (12) in a slubbing machine (flyer), the flyer (7) and tube (2) or bobbin are to be moved relative to one another within a winding stroke limited by limit switches (18, 19, 22) or the like. After the desired diameter has been re...

Disclosed herein is a one-part adhesive which comprises a mixture of: (a) a polymerizable ethylenically unsaturated urethane polymer; and(b) a polymerizable ethylenically unsaturated acid, acid salt, or acid anhydride wherein component (b) is present in an amount in the range of from 0.5 to 50 weight percent of component (a). Such an adhesive is especially suitable for bonding components together ...

Polyurethane foams prepared from the reaction of polyester polyol with organic isocyanate have improved flame retardance and dripping ember retardance by incorporation of an additive comprising (1) halogenated flame retardant, and (2) organic solvent soluble glycoluril-formaldehyde material.

An osteosynthetic compression plate with holes for the insertion of bone screws, with a cross-section that is trapezoidal or otherwise provides for a decreased plate surface against the bone while providing necessary rigidity.

A rubber article having an indicium on the surface of said article, characterized by said indicium having a surface of a first finish, the surface of said article substantially surrounds said indicium having a second finish which is different from said first finish such that a readily visual distinguishable appearance can be seen between the surface of said indicium and the surface substantially s...

A pneumatic tire (A) includes a body having a crown (10) with a ground-engaging tread portion (20), a pair of sidewall portions (12, 14), as well as a pair of bead portions (16, 18). An annular substantially inextensible bead reinforcing member (36) is positioned in each of the bead portions (16, 18). A carcass ply (30) is positioned in each sidewall (12, 14) and the crown (10) and extends from on...
