Procédé d'épuration d'un milieu aqueux, contaminé par de l'étain, selon lequel on traite le milieu aqueux avec du silicate de métal alcalin, en sorte de former un composé solide avec l'étain et on sépare ledit composé solide. Le procédé s'applique aux liquides aqueux recueillis de l'épuration de fumées produites par l'incinération de déchets industriels, ménagers, urbains ou hospitaliers.

A glass fiber cord for reinforcing a rubber is disclosed, which is inexpensive and suffers no decrease in strength even when flexing stresses are repeatedly imposed thereon under high load at high temperatures, and which has sufficient heat and water resistance. High-strength glass filaments having a diameter of 8-10 .mu.m are bound to obtain a strand, on which a coating layer comprising a resorci...

A method of making a semiconductor device, comprises the steps of providing an insulating layer, forming a series of holes in the insulating layer, depositing a first layer of a metal, or a compound thereof, on the insulating layer such and in the holes, f orming a dielectric layer on the first layer, the dielectric consisting of a compound of the metal, and forming a second layer of the metal, or...

The implant, which is supple, pre-filled or inflatable, can be, in the form of a hollow envelope (1) containing a substance (1a) in liquid or paste form to give it the consistency of soft tissues. Its outer surface can be smooth or have frond-like projections, and prior to use it is coated with a gel (3), which can be in a dry form which becomes a gel after implantation. The implant, which is sup...

The roller skate comprises a chassis (2) with rollers (3) and a removable boot fixed to the chassis at four non-aligned points. Locking of the boot to the chassis is automatically ensured by deformation of a spring during booting up, The automatic locking comprises a fastening and locking part (8) subject to the action of a locking spring (16). The skate has an unlocking lever (19) articulated in ...

The knob stem (3) of the hydrant (5) can only be moved by a key with a body (9) which engages in the knob stem and which is joined to a handle by a rod. The knob stem has a base in non-magnetic material (7) such as bronze. The knob stem is attached in the usual way to the activating rod (11) and rotates by the application of its base on a bearing (13) attached to the hydrant. The bearing is also m...

The cage comprises a one-piece body made up of two parallel branches (1, 2) with a posterior connecting piece (3) between their two ends (13, 23). A bolt (5) with a threaded shank (53) passes between the two branches and screws into a hole in the connecting piece, while its head (51) makes contact with facing thrust surfaces (41) on the inside of the branches to expand their anterior ends. The con...

Comminution, two-stage mechanical separation, cleaning and two-stage density separation (14, 16) are used in any order, to separate and clean waste plastics from any source. An Independent claim is included for the corresponding plant. Preferred features: Two specific processing orders are exemplified. First and second phases of density separation each comprise one or a series of stages and may ...

A method wherein a feedstock consisting of a powdered and/or particulate material with a variable particle size is impregnated with a solution of a polyelectrolyte that is capable of being chemically combined with at least one of the components of the feedstock. The polyelectrolyte may be an ionic polymer having covalent bonds between long-chain molecule components and the available ionic bonds. T...

The present invention is a process for obtaining a fragment of bovine DNA which has a defined size and is specific to bovines, and in particular the species Bos taurus and Bos indicus, from a sample of organic matter, and a process by which a defined sequence of the bovine genome present in bovine genomes but absent from the genomes of other animal species is amplified by a polymerase chain reacti...
