Acmade Foot-Operated Splicer * with Tungsten j Tipped Blades Combination 16mm-35mm Model $1495 This splicer is constructed, as is usual with ACMADE products, of the finest mate rials and workmanship. All castings are of the best quality and the top body and cutter arms are seasoned to prevent dis¬ tortion after machining. The machining is carried out to limits of± .0005" in order that the cutter blades shall close in a dead parallel manner. The cutter blades are made from stainless steel with Tungsten Carbide inserts, and afterwards ground lapped and polished to a limit of ± .0002" thickness and the cutting edges relieved by 1°. The Tungsten Carbide inserts will have indefinite life and will not require sharp¬ ening as with other types. A heater unit is installed in the top body of the machine. The top light in a well glass fitting is at¬ tached to the body of the machine and also an inspection light in the waste bin to¬ gether with cement bottle and brush. A scraper block is supplied and also a scraper block setting jib and support shelf rubber-covered. The whole machine is fin¬ ished in first quality grey hammer and all metal parts other than cutter blades are hard flash chromed. ACMADE MARK II EDITING TABLE $3295 f.o.b.

ZOOM LENS MOTOR Continued From Page 169 found that operating the motor at around 6 to 10 volts produces a slow, pleasing zoom with a smoothness rarely obtainable through manual operation of the lens. The 5-pole, double-throw, on-off-on toggle switch, shown at 6 in Fig. 2, determines the electrical polarity fed to the reversible motor. With the switch in forward position, the zoom lever moves forward; in the extreme reverse position it causes the zoom lever to move backwards. In the central posi¬ tion, the switch is off. In operation, if the motor driven zoom lever is not stopped at any inter¬ mediate point and is allowed to con¬ tinue until it contacts the micro-switch that arrests its movement, halting the operation in no way adversely affects the zoom control mechanism and the zoom comes to a smooth stop. Where the switch is moved from one operating position to the other to reverse the direction of the zoom, i.e. — from a zoom-in to a zoom-out — the torque of the motor is reversed and a smooth change in direction of the zoom is effected. Still another feature inherent in the control switch described above is the means it provides also to stop and start the camera motor simultaneously with operation of the zoom lens, when de¬ sired. The camera motor is powered by a separate battery and can he switched on simultaneously as the zoom control switch is moved to either “on” position.
