A device for guiding a cable 21 between adjacent annular grooves 13 on a winch drum 12, comprises a channel 14 parallel to the drum axis and along the drum surface to permit the cable to change grooves, and a cable guide nut 20 mounted on a feed screw 18, intermittent rotation of which is controlled by a Geneva cam mechanism which causes rotation of the screw once per drum revolution as the channel 14 arrives adjacent the nut 20. The cam 22 is keyed to the screw shaft 17 and recesses 23 in the cam are engageable by a roller 30a carried by an arm 31 rotatable with the drum, whereby the cam is moved an increment for every drum rotation. A further roller 30 mounted coaxially with the roller 30a engages a T-shaped cam locking segment 24 which is thereby displaced transversely of the cam axis to unlock the cam as the roller 30a approaches. The locking segment which is spring biased into locking position comprises either a detent 34 for reception in a cam recess 23 or a toothed section for engagement with teeth formed on the periphery of the cam 22.

Title: Process for polishing semiconductor crystals
IPC: H01L21/302
Filed: 1965-12-29
Abstract: A method of polishing semi-conductor crystals comprises placing the crystals in a liquid chemical etching bath, stirring the etchant to establish a flow of etching solution across the surfaces of the crystals at a rate which is sufficiently great to eliminate convection currents in the liquid and to keep the crystals in constant motion, but which is also below the rate at which turbulence in the flow would occur at the crystal surfaces. The stirring may be effected by rotating a paddle-wheel below the surface of the etching liquid. Specified crystals are silicon and germanium. The etching liquid may be a mixture of nitric and hydrofluoric acids and optically contains additives such as acelic acid, bromine, iodine, sodium dichromate, silver or mercuric nitrates and organic wetting agents.
