[bryansk]

Здравтсыуйте!
Пожалуйста, помогите перевести: adjusting slide; continuously displaceable.

Выражения встречается в следующем контексте:
(описание устройства конвейера)
The аrticles are moved on the main transport chain through this tunnel. Simultaneous the articles rotate continuously with the help of the beside-drive chain and the turn able article holders.
The return station is fitted on an adjusting slide. This is used to tension the chain and equalise its length. The slide is continuously displaceable, being pressed outwards by an air cylinder, whereby the chain is tensioned

Заранее спасибо

adjusting slide - это скорее всего направляющие (салазки) для регулировки натяжки цепи
continuously displaceable - выдвижные
