Abstract

Highly crystalline polymer of a 3-6c alpha-olefin Is produced wth a catalyst obtained by mixing (i) a Ti trihalide (pref. TiCl3 or 3TiCl3.AlCl3), (2) AlRnX3-n where R is 1-8C alkyl; X is halogen n is 2 or 3, and (3) P(SR1)3 or O = P(SR1)3 where R1 is a 1-20 hydrocarbyl group, the molar ratio of (2) to (1) being from 1:0.1 to 1:10 and the molar ratio of (2) to (3) being from 1:0.005 to 1:5. Component (2) is pref. Et3Al or Et2AlCl and component (3) is suitably trilauryl trithiophosphite.

Description

Gegenstand des Hauptpatentes ist ein Sicherheitskabel, insbesondere für elektromotorisch betriebene Rasenmäher, bei welchem das Kabel einen Hilfsleiterkreis mit wenigstens einem Leiter aufweist, der im Querschnitt des Kabels derart untergebracht ist, daß er im Falle einer Beschädigung des Kabels durch ein Messer od.dgl.The subject of the main patent is a security cable, in particular For lawnmowers operated by electric motors, in which the cable has an auxiliary conductor circuit having at least one conductor housed in such a way in the cross section of the cable is that he or the like in the event of damage to the cable by a knife.

von diesem noch vor Berührung der Hauptleiter erfaßt wird und dadurch über den Hilfsleiterkreis eine Abschaltung der an den Hauptleitern liegenden Spannung bewirkt.by this before touching the main conductor is grasped and thereby The voltage applied to the main conductors is switched off via the auxiliary conductor circuit causes.

Die vorliegende Erfindung bezieht.sich auf eine weitere Ausgestaltung des im Kabel eingebetteten Hilfsleiters selbst. Gemäß der Erfindung ist der Hilfsleiter als kupferumsponnener Textilfaden, insbesondere Baumwollfaden, ausgebildet. Dieser Kupfer umsponnene Baumwollfaden kann einzeln oder gebündelt an Jener Stelle des Kabels untergebracht werden, an der er bei einem eventuellen Schnitt des Messers vor Berührung der Hauptleiter durchgetrennt wird.The present invention relates to a further embodiment of the auxiliary conductor embedded in the cable itself. According to the invention, the auxiliary conductor is designed as a copper-covered textile thread, in particular cotton thread. This Copper-braided cotton thread can be used individually or bundled at that point of the Cable to be accommodated, on which he should be in a possible cut of the knife before touching the main conductor is severed.

Die Verwendung derartiger kupferunsponnener Baumwollfäden hat den Vorteil einer höheren Elastizität,als dies bei massiv gezogenen Kupferdrähten der Fall sein könnte. Die Flexibilität des Kabels wird durch die Einbettung derartiger Hilfsleiter, die aus kupferumsponnenen Hilfsdrähten bestehen, in keiner Weise beeinträchtigt.The use of such copperunspun cotton threads has the Advantage of a higher elasticity than with solid drawn copper wires Could be case. The flexibility of the cable is increased by the embedding of such Auxiliary conductors, which consist of copper-braided auxiliary wires, are not impaired in any way.

Anstelle des kupferumwickelten Baumwolifadens könnten auch gebündelte Kupferlitzen mit sehr feinen Einzeldrähten benutzt werden, jedoch erscheint aus GrUnden der Flexibilität die Benutzung von Baumwolifäden vorteilhafter.Instead of the copper-wrapped cotton thread, bundled ones could also be used Copper strands with very fine individual wires can be used, but appears to be off For reasons of flexibility, the use of cotton threads is more advantageous.

Die für die Erfindung vorgesehenen kupferumsponnenen Baumwollfäden sind handelsüblich und brauchen daher nicht im einzelnen erläutert zu werden.The copper-spun cotton threads provided for the invention are customary in the trade and therefore do not need to be explained in detail.
