A thermoplastic elastomer is disclosed which is a combination of a non-elastomeric polyolefin and two different non-crosslinked elastomers and optional softening oil. The all-digital phase-locked loop includes a digitally controlled oscillator, a phase detector, a loop filter, and a bandwidth modification unit. The ball feeder also includes a scoop for receiving a single transverse row of balls at the outlet end of the funnel and elements for raising the scoop into an elevated position in which it defines a second ramp extending transversely of the first mentioned ramp and in which it can release the balls one at a time. When the page split is caused by appending monotonically increasing values at an end of the table, the sorted order will guarantee that the new page is empty. The suture retainer may include sections which have surface areas which are bonded together.
