In order to assure the geometric uniformity of a tire molded with a segment mold when the sculpturing of said tire includes blocks 11 surrounded by recesses formed by grooves 15 and incisions 16, the said grooves 15 are thinned at the level of the joint planes 550 between segments. Furthermore, wear indicators 17 are arranged at the level of the joint planes 550 between segments.

PROCESS FOR THE PRODUCTION OF RIGID FOAMS CONTAINING URETHANE AND ISOCYANURATE GROUPS Rigid foams containing urethane and isocyanurate groups are obtained by using of mixtures of i) n-pentane and/or isopentane and ii) cyclopentane as blowing agents.

UNLEADED AVIATION GASOLINE Unleaded aviation gasolines having heats of combustion and octane qualities deemed necessary for use under actual service conditions are formed from blends of specified proportions of aviation alkylate, ether blending agent, a cyclopentadienyl manganese tricarbonyl and optionally other appropriate hydrocarbons falling in the gasoline boiling range.

The present invention provides a water dispersible particulate polymer composition having improved water dispersibility comprising a water soluble particulate polymer which has been contacted with a finely divided particulate dispersant comprised of at least one insoluble or sparingly soluble fatty acid or salt thereof so that the particles of the water soluble particulate polymer have dispersed t...

Apparatus and an accompanying method for implementing a communications protocol for use in generally a distributed, and particularly a highly parallel, multi-processing system, for communicating application data of arbitrarily varying strides between separate processors and generally without the need for intermediate data storage. Specifically, application data is transferred through a succession ...

A direct contact cryogenic crystallizer having a vertically oriented draft tube (16) into which cryogenic fluid is injected at a high velocity along with warm gas and through which a crystal slurry is drawn for subsequent cooling and agitation for the production of crystals.

A process is provided for producing elastomeric compositions by forming a mixture of polymeric material, a reinforcing agent, a processing aid and a vulcanizing agent. The process of the invention is continuous and includes the repeated, sequential steps of admixing the polymeric material along a first mixing zone defined by a space wherein the gross energy applied induces a first operating temper...

Peptides of formula (I) and their salts are new. - H2N-W-Ser-Asp-Lys-X-OH (I) - (X = Pro, Lys or a valence bond, W = Thr, Pro or a valence bond, with the proviso that if X = Pro then W is also Pro).

Novel pseudoceramides are compounds with a general structure (2): In this formula a is 0 or 1, b is 0 or 1 but if a is 0, b is also 0 and R has 1 to 8 carbon atoms. The substituents R and R<1> are a range of substituted or unsubstituted aliphatic hydrocarbon substituents. R<2> is hydrogen, a sugar residue, a sulphate residue or a phosphate residue. R<3> is hydrogen or a fairly short cha...

A method and apparatus for encoding/decoding of background sounds. The background sounds are encoded/decoded in a digital frame based speech encoder/decoder. First, it is determined whether the signal that is directed to the encoder/decoder represents primarily speech or background sounds. When the signal directed to the encoder/decoder represents primarily background sounds, the temporal variatio...
