Abstract: This invention relates to apparatus for producing a periodic output signal having a predetermined period ratio a/b relative to a periodic input signal.Signals from a tachometer on a gearbox are received by a counter timer unit (11), the counter timer unit evaluates the number of clock pulses k° received from a clock (10) within each period of the tacho signal. A control unit receives values of k° from the counter timer and employs an algorithm based on the following equation to calculate a count value n° to be loaded into a register (30) for the next tacho period.where dK represents k<sup>-1</sup> - k°.An accumulator (17) is connected via an adder (31) to the register (30) and at receipt of each clock pulse from the clock (10) adds the count stored in register (30) into the accumulator (17. An output is produced on line (34) when the accumulator (17) overflows.

Abstract: In a circular cold saw (1) with a saw blade (6) entering during sawing into the material (5) to be worked from below through a slot (4) in a support plate (3) of a support table (2), the direction of rotation of the saw blade (6) during sawing is selected in such a way that the saw teeth (11) cutting in each case move away from the pivot bearing (7) of the saw-blade arm (8). This results in a position of the resultant of the cutting force at a slight distance, if any, from the pivot bearing (7) so that the feed is considerably relieved of load relative to a reversed direction of rotation of the saw blade (6). <IMAGE>

Abstract: A disposable, sterilizable cable drive unit for an intravascular blood pump includes a rotor enclosed in a fluid-tight enclosure which can be slipped into the stator of a drive motor. The unit is connectable to a constant-rate purge fluid supply and to a dual-lumen cable sheath. One lumen provides a sterile purge fluid path; the other carries the drive cable to the blood pump and provides a return path for a flushing fluid in which the cable is immersed. The flushing unit is derived from the purge fluid supply at a constant rate, and the rotor may also be immersed in it if desired. The unit is held in the drive motor by a manually operated detent, and the self-centering action of the rotor aligns it with the stator when the motor is energized. The motor is mounted on a gimbal so as to be alignable with the cable sheath at its point of insertion into the patient's vascular system, in order to prevent stresses on the patient and kinks in the cable sheath.
