Abstract: A tapered running block and corresponding tapered cavity blocks are utilized in a mold for fabricating relatively thin, flat plastic cards, such as used for pre-paid telephone cards and the like. The mating surfaces of the runner block and the cavity block are angularly tapered; so that metal-to-metal contact is made between the runner block and the cavity block when the mold is in the plastic injection position. As soon as relative movement of the runner block and the cavity block is effected to part the blocks and separate the cards from the runners, the tapered 1surfaces move away from one another without any sliding contact, thereby significantly reducing wear in the mold.

Abstract: A tubing tightener which is readily adaptable to either clockwise or anti-clockwise rotational setting operation and which uses a series of drag slips having integral drag and slip surface regions. The drag surface regions are substantially smooth and are advanced into contact with a wellbore with the slip surface regions retracted, when the tightener is in its unlocked orientation. The slip surface regions are serrated to provide a positive engagement with the wellbore and are advanced into engagement with the wellbore with the drag surface regions retracted, when the tightener is in its locked orientation. The drag slips are caused to rock about a point of contact between the drag slip surfaces and the wellbore, located intermediate the drag and slip surface regions, in order to advance the appropriate surface region of each drag slip into engagement with the wellbore. The invention provides for a compact, lightweight construction with improved reliability and increased bypass around the tightener.
