Abstract

"CONJUNTO DE ANEL DESLIZANTE ENERGIZADO". O presente certificado de adição refere-se a um conjunto de anel deslizante que inclui um anel deslizante e um conjunto de contato elétrico. O anel deslizante define uma circunferência e uma ranhura de contato elétrico que estende-se ao redor da circunferência do anel deslizante. O conjunto de contato elétrico de preferência inclui uma pluralidade de contatos elétricos espaçados ao redor da circunferência do anel deslizante para acoplar a ranhura de contato elétrico. Além disso, um mecanismo de impulsão está de preferência associado com cada um dos contatos elétricos para impelir os contatos elétricos para o acoplamento com a ranhura de contato elétrico. Finalmente, um raspador está de preferência associado com cada um dos contatos elétricos para extensão dentro da ranhura de contato elétrico para inibir um fluido de passar através da ranhura de contato elétrico."ENERGIZED SLIDING RING SET". This Certificate of Addition refers to a slip ring assembly that includes a slip ring and an electrical contact assembly. The slip ring defines a circumference and an electrical contact groove that extends around the circumference of the slip ring. The electrical contact assembly preferably includes a plurality of electrical contacts spaced around the circumference of the slip ring to engage the electrical contact slot. In addition, a drive mechanism is preferably associated with each of the electrical contacts to propel the electrical contacts into the coupling with the electrical contact slot. Finally, a scraper is preferably associated with each of the extension electrical contacts within the electrical contact slot to inhibit fluid from passing through the electrical contact slot.
