Abstract: ABSTRACT OF THE DISCLOSURE         A device for continuously winding a continuous elongate element, especially a strand formed by gathering together a large number of glass filaments drawn from a bushing, provided with two or more main winding spools which are adapted to be brought to a predetermined winding position one by one and an auxiliary winding spools which is normally held in an inoperative position spaced apart from the winding position by such a distance as not to interfere with the operation of the main winding spool in the winding position and, whenever the main spool in the winding position becomes full, is brought into engagement with this main spool in coaxial relationship and rotates at the same speed as the winding speed of the main spool.  The strand is transferred from the full main spool to the auxiliary spool connected to the former and after an empty main spool is brought to be engagement with the auxiliary spool in place of the full main spool, the strand is transferred from the auxiliary spool to the empty main spool.  In this manner, even when the full main spool is replaced with the empty main spool, the winding of the strand is continued at a substantially constant speed.          The auxiliary winding spool further may have a built-in strand cutter which acts to cut off the strand bridging between the main spool and the auxiliary spool in a moment when the both spools are disconnected from one another.

Abstract: HYBRID DIAMOND INSERT PLATFORM          LOCATOR AND RETENTION METHOD             ABSTRACT OF THE DISCLOSURE      This concept discloses a new technique which uses brazing or diffusion bonding methods to attach a dia-mond disk to a wedge-shaped steel support platform on a hybrid type of bit.  The invention is primarily concerned with the attachment of the innermost diamond cutting disk on the wedge-shaped drag bit face portion of the hybrid bit.  It is particularly difficult to secure any kind of cutting structure to the innermost portion of a rock bit because of the lack of material available to secure the cutting structure to the drag bit face.  Space limita-tions on the drag bit face prevent the use of conventional interference fit diamond insert studs for the innermost cutters.
