The process consists in casting an insert in a first mould, in arranging the insert thus cast in a second mould and in casting the part in this second mould around the insert, so as to form a mechanical link between the two castings. The wear-resisting part thus cast advantageously comprises an insert with a high resistance to wear, whilst the rest of the part is made from a more ductile material ...

The prepn. of a catalyst for structural isomerisation of a linear 4+c olefin to its corresp. methyl branched isoolefin involves: (a) mixing (i) zeolite powder comprising at least one zeolite with \- one-dimensional pore structure having a pore size sufficiently small to retard by-prod. dimerisation and coke formation and sufficiently large to allow entry of the linear olefin and formation of the i...

A method is provided for selectively producing a trans-geometrical isomer of non-conjugated diolefins. The method comprises treating a starting non-conjugated diolefin isomer or mixture of isomers, a first mono-olefin and a second mono-olefin with a metathesis catalyst under selected reaction conditions to produce a product with greater than 80% trans-geometrical isomer content. In a preferred emb...

The invention provides a urea based solid composition and a process for preparing a homogeneous, urea-based, solid cleaning composition. Cleaning compositions for use in warewashing and cleaning hard surfaces, rinsing, sanitizing, deodorizing, and the like, made by the method are also provided. The ingredients are charged into a heated mixing apparatus and when uniform are transferred into a mold ...

A method for classifying regions in a digital image as either photo regions or non-photo regions is presented. A digital image is divided into regions and each region is divided into a plurality of cells. Each cell comprises a group of pixels represented by one or more digital bits. Features of a cell such as its graylevel spread, or the moment of inertia of its co-occurrence matrix, are used to d...

A lightweight cement composition for use in high pressure environments (greater than 3000 psi) comprises an aqueous slurry of a hydratable cement, ceramic microspheres and a foaming surfactant. It has been found that the presence of the foaming surfactant synergistically overcomes the normal tendency of the ceramic microspheres to crush at a pressure greater than about 3000 psi.

In the process, a metabolically active bacterial population is cultured and maintained in a reservoir with a supply of substrate, from which reservoir biomass is transferred to a biological treatment stage continuously or at intervals.

The multi-component system is suitable for processing by the Hatschek process and other processes known in the building material industry.
