A process for reclamation of recycled polyvinylchloride comprises plasticization of recycled polyvinylchloride preliminarily washed of dirt and disintegrated, under constant stirring at a temperature of 60 - 80 DEG C, using a plasticizer containing not more than 11 wt.% of polyorganosiloxane, followed by modification of recycled polyvinylchloride at a temperature of 60 - 80 DEG C with a 4 - 12% so...

The subject invention is directed to a rheology-modified ethylene polymer having less than 0.5 weight percent gel, a composition distribution breadth index (CDBI) greater than 50 percent, and a molecular weight distribution (Mw/Mn) of less than 4.0, which is characterized as having improved rheological performance and/or melt strength attributes relative to the unmodified polymer. The subject inve...

An inorganic binder system for foundry compositions including a silicate and added phosphate. The composition produces a binder having the advantageous strength properties of a silicate binder system with the dispersibility properties of a phosphate binder system. Methods of making and using the binder systems and the resulting products are of particular interest to the foundry art.

A laparoscopic surgical technique is provided for preparing a site for implantation of a fusion device or implant. In accordance with one embodiment of the technique, a laparoscope (170) is provided having an outer sleeve (171) with distraction fingers (173) at one end to distract the disc space (D).

A close-fitting wrapper for a product (P) is obtained from two sheets (1, 2), the first of which is formed into a hollow shape so as to wrap around part of the product (P). The other sheet (2) is applied over the remaining part of the product (P) so as to take on a shape complementary to that of the product itself. In order to seal the wrapper, the two sheets (1,2) are joined peripherally over a f...

The present invention is related to a method used for giving the surfaces of natural stones such as marble, travertine, etc., an aged and weathered appearance. This method is realized by using wire brushes instead of abrasives being a kind of grindstone, on the abrasive heads of the polishers used in the existing natural stone processing technique; this provides the natural stones with a surface o...

The invention relates to a method and an apparatus for induction sealing of a packaging material (2) which includes a layer of aluminium foil. The apparatus includes an inductor (1) with two parallel slightly spaced apart conductors (3) which are disposed in an electrically insulated carrier portion (4). The conductors are connected to one another and to a high frequency current source by means of...

This invention relates to the plastic / metal laminates (e.g. plastic wire armours or screened belts) with improved friction, adhesion and melted coating properties and contains at least one metallic sub-layer and a thermoplastic adhesive layer adhered on at least one surface of this sub-layer; this layer contains embosser in sufficient amount to reduce friction coefficient of the laminate and emb...

The grinder grinds a fitting (84) pulled onto a carrier via a grinding element and a setting element (76,78,82) to press the grinding element against the fitting. The setting element has an elastically deformable pretensioning device to guide the grinding element in the pressing direction during the grinding process. There may be a stop element to fix the grinding element in a rest position, and a...

A process for efficiently utilizing phosphorous acid or salts thereof as a chain transfer agent in the polymerization of monomers, particulary unsaturated carboxylic acid monomers, is provided, where the polymerization is conducted at an in-process solids level of at least 40 percent and in-process neutralization level of at least 30% to produce low molecular weight water-soluble phosphonate-termi...

A zip fastener 2 has formations 32, 34, 36 on the stringer tapes 8, 10 which hinder the movement of the sliders 18, 20 relative to the tapes 8, 10. The movement of the sliders 18, 20 past the formations 32, 34, 36 can be felt by the user and so helps indicate when the sliders 18, 20 are in position at the bottom of one tape 8, ready to receive the male movable open parts pin 42. The formation 32 r...
