This invention relates to an improvement of the adhesion of brass-coated steel tire cord to a vulcanized rubber composition. The adhesion is obtained by adding an aromatic triazole and an organo cobalt compound to an unvulcanized rubber compound in order to obtain metal-rubber bonding when vulcanized. Tires formed by the above process have good resistance to heat and moisture.

The bond strength between a sulphur-vulcanizable rubber and a metal, especially brass, is increased by using as bonding promoter an organic substance containing one or more groups of the formula -S-SO2R where R represents (a) a radical -OM where M is a monovalent metal, the equivalent of a multivalent metal, a monovalent ion derived by the addition of a proton to a nitrogeneous base or the equival...

A composition obtained by mixing fly ash, calciumsulphate hemihydrate and oxisludge, a product caught from gases emanating from converters during steel production. Oxisludge containing substantial amounts of iron is used in an amount comprised between 0,2 and 10%, preferably 1 to 5%. The composition is a loose mass or consists of granular products.

3,7-diaza bicyclo-(3,3,1)-nonane compounds of the formula I in which substituents R1, R2, R3, R4, Z1, and Z2 indicate the substituents as they are given in the description of the invention, can be employed to produce certain pharmaceutically useful compounds.

Leakage of the cooling liquid in blast furnace nozzles is detected by measuring variations in the differential pressure of the cooling liquid using an electronic information system with the technology normally employed in inductive-type systems and capable of detecting minor liquid leakages which are not detectable with conventional control devices. Detection assemblies are incorporated at the coo...

PURPOSE:To improve the operating rate of a vulcanizer by assembling a die and a die heating hot plate into the vulcanizer as put together after a preheating outside it when a die is exchanged. CONSTITUTION:Dies 4 and 6 are mounted on hot plates 3 and 8 respectively and they are preheated at a proper position of a vulcanizer passing a steam through upper and lower hot plates 3 and 8. Thereafter, wh...

PURPOSE:To enable the positioning of a die on a vulcanizer, labor saving in the attaching and detaching thereof and automatization by arranging an arm for supporting an assembly of a hot plate and a die, a die exchanging truck, a positioning member and a clamping means. CONSTITUTION:An arm 17 is provided on the top of a frame of a truck A in such a manner as to move into and out of it freely and a...

PURPOSE:To prevent variation in the space of upper and lower bead rings regardless of any leakage of a cylinder packing during the shaping by linking a center post to an upper ring through a collar while passages of the upper ring, the collar and the center post are connected together. CONSTITUTION:A gas left in a tire T is discharged outside via paths 8b, 11b and 19a. When the space between upper...

The adhesion of self-bonding, low modulus, one package, room temperature vulcanizable silicone compositions to a variety of substrates is effectively promoted by incorporation in the silicone composition, before curing, a small effective amount of an adhesion promoting composition comprising predominantly at least one diorganocyclopolysiloxane compound of the formula: wherein R1 may be C...

PURPOSE:To improve the S/N of a reproducing signal, by feeding back a part of the reflected light from a recording medium to a semicnductor laser. CONSTITUTION:The phase of a phase plate 25 is shifted by a prescribed amount from lambda/4 (lambda is wavelength) so as to feed back about 5-15% of the reflected light from a disc 8 to a semiconductor laser 1 at all times. When the luminous amount to be...

PURPOSE:To ensure that penetration of bubbles into a printing head hardly occurs at the time of carrying, by a method wherein an ink-supplying port for supplying an ink contained in an ink container to a printing head is provided at a position on the same plane as a nozzle and a pressure chamber and substantially diagonal to and on the lower side of the nozzle. CONSTITUTION:An ink passage consisti...

PURPOSE:To form a new optical reversible recorder and reproducer which is small in size and is capable of erasing, recording and reproducing at real time, by obtaining the condition of temperature rise/rapid cooling and temperature rise/gradual cooling from the difference in the length of thermal distribution of a minute spot light along a guide track.
