PURPOSE:To uniformize pressurizing force and to shorten a pressurizing time, by providing a U-shaped bent point to the outside of a bladder main body and making the wall thickness of said bladder main body gradually thin from the part corresponding to the bead part of a green tire to the part corresponding to the tread part thereof. CONSTITUTION:A bladder 30 is formed so as to make the wall thickn...

PURPOSE:To uniformize pressurizing force and to shorten a pressurizing time, by forming a bladder so that the pressurizing stretchable part thereof has a curved protruded cross-section and making the wall thickness thereof gradually thin from the part corresponding to the bead part of a green tire to the part corresponding to the tread part thereof. CONSTITUTION:When a cylinder is driven, a center...

A powder metallurgy consolidation process in which the unconsolidated metal powder is placed in a sealable mold; the mold is evacuated and sealed; the mold is placed in an open top container larger than the mold; the space between the mold and container is filled with a free flowing refractory powder, preferably minus twenty mesh powder graphite; and the sealed mold and its contents are heated in ...

A method in the manufacture of steam-cured light-weight aerated concrete having hydrophobic properties, comprising preparing an aqueous expandable and solidifiable slurry, one or more hydraulic binders and one or more silica-containing materials casting the slurry in a mould; expanding and solidifying, and optionally cutting the solidified slurry; and steam-curing the resultant light-weight aerate...

An adhesive composition and a method for its use in bonding rigid PVC elements. The adhesive composition comprises: (1) a first dissolved PVC polymer having a K-value of about 58 +/- and a second dissolved PVC polymer having a K-value of about 45 to about 52; (2) at least one cyclic organic solvent; and (3) at least one non-cyclic organic solvent.

Conductor bundles for the concentric coils of a dry inductor having no iron core. The coils define cooling air gaps therebetween, adjacent ones of the coils being electrically connected in parallel and each coil being comprised of turns of a conductor bundle of the same rectangular cross section, the coils having different numbers of said turns. The conductor bundles form the turns of the coils an...

A novel fluorinated copolymer is prepared by copolymerization of a fluorinated olefin with a novel sulfur containing fluorinated vinyl ether of the formula: wherein k is 0 or 1 and l is an integer of 3 to 5, which is prepared from starting materials which are also novel. Said copolymer is useful for preparation of a fluorinated cation exchange membrane having carboxylic acid groups and...

The invention relates to apparatus for the treatment of sewage or other aqueous waste material having a biochemical oxygen demand in a single tank, the treatment involving the oxygenation of the sewage. With reference to FIG. 1, a volume of sewage in a treatment tank 110 establishes itself naturally into an upper layer 124 of clear liquid and a lower layer of liquid containing bacterial sludge. Li...

This relates to the formation of wide mouth bottles and jars for receiving a hot fill product where the jars and bottles are formed of a suitable polyester such as PET. The bottle or jar is initially formed as part of an intermediate article including an upper adapter portion which is reusable so that substantially all of the resultant bottle and jar, particularly the neck finish thereof is biaxia...

PURPOSE:To mold a bracket in integral relation to a hollow molded body at a position other than a mold split surface, by drawing the bracket forming area of a parison near to the grasping space of a parison grasping jig by drawing a vacuum to grasp the same by said parison grasping jig. CONSTITUTION:When a movable mold is retracted to open a mold, a parison grasping jig 9 is issued from a receivin...

The invention relates to a coil arrangement for producing a homogeneous magnetic field especially for application to so-called NMR-imaging. An object of the invention is in terms of the size of a coil arrangement to expand the homogeneous area produced by a coil arrangement and, at the same time, to maintain the design of a coil arrangement simple and its manufacturing costs low. According to the ...
