Title: Method and appliance for blocking off an underground pipe without using a trench
Inventor: MCGOWAN JOHN B
IPC: F16L55/128

Title: Process for the production of mouldings from modified thermoplastic polyamides
Inventor: SCHMID EDUARD
IPC: C08J3/22
Filed: 1984-10-29
Abstract: Mouldings produced from specifically structured thermoplastic polyamides have better mechanical resistance and increased heat distortion resistance if the processing is carried out with addition of a substance which links chains in the presence of water. To this end, a masterbatch comprising a thermoplastic as support and a silane which is reactive with polyamide and hydrolyses rapidly with water is added to the dry polyamides, which preferably have an increased concentration of amino groups (-NH2, -NH-), before or during processing. In the melt state, the silane reacts with the polyamide, while simultaneously the masterbatch support is finely distributed or even dissolved in the polyamide. The melt is then converted into the finished use article, preferably by injection moulding or extrusion. Even on contact with the normal ambient atmosphere, during which the polyamide adsorbs moisture from the air, the linking reaction of the polymer chains takes place, giving a higher use value of the article by increasing, for example, its heat distortion resistance.

Patent CH-657287-A5 (CH)
Inventor: SPIEWOK LEONHARD
IPC: B04B7/16
Filed: 1982-09-27
Abstract: In a centrifuge sieve drum, wherein the inner surface of the drum is lined with a support arrangement carrying wear-resistant sieve or screen rods, there is obtained a compensation of the different thermal expansions of the sieve rods and the support arrangement in that, the sieve rods comprise an axially extending web and the support arrangement comprises identically shaped grooves or slots engaged by the webs. Each web and its associated groove or slot may be designed, for example, as a dovetail guide. Thus, while the sieve rods may expand or contract in longitudinal direction or in the direction of the lengthwise axis of the drum, the sieve rods are, however, immovable in radial direction and in circumferential direction. Such a support arrangement can be efficiently manufactured by simultaneously cutting, such as by milling the grooves or slots and sieve openings or slots in a convex outer surface using a triple cutter, such as a milling cutter, and by subsequently bending the supporting arrangement to form a concave surface and inserting the same into the drum.
