Hohles Metallobjekt und Verfahren zu seiner Herstellung

Die Herstellung von hohlen Metallobjekten mit engem Durchmesser unter Verwendung von schwierig plastisch zu bearbeitenden Metallen ist mit herkömmlichen Herstellverfahren problematisch; je enger der Durchmesser, desto höher die Herstellkosten, und unter manchen Umständen war die Herstellung unmöglich. Mehrere Metalldrähte werden zu einem verdrehten Drahtballen verarbeitet, benachbarte Metalldrähte werden in planaren Kontaktbereichen in Kontakt gebracht, und der Ballen wird vereinigt durch Zuführen eines Festigermittels entlang der Außenseite, wodurch ein hohles Metallobjekt hergestellt wird, das einen gleichmäßigen Innendurchmesser und eine saubere Innenfläche hat.

Safety cable for a ski piste preparation vehicle, to anchor it on steep slopes, has an optic fiber within the outer strands coupled to a light source at one end to prevent accidents

The wire cable with an optic fiber strand, especially as a safety cable for a vehicle preparing a ski piste, has the optic fiber (10) in the outer gap between two outer wire strands (3), or within a dedicated groove (11). An intermediate plastics mass (2) forms a layer between the outer strands and the inner core (1). The optic fiber is of plastics clad silica (PCS) connected to a light source at one end, and neighboring wire strands can be given a luminescent coating.

Abrasion resistant omnidirectionally reflective retractable pet leash

A flexible abrasion resistant omnidirectionally reflective retractable pet leash has an omnidirectionally reflective pet leash housed within a retractable housing device. The omnidirectionally reflective pet leash reflects an incoming light beam back in the same direction as it was emanated.
