Patent CA-2393341-A1 (CA)
Title: Spindle for machine tool
Inventor: NORSELLI ANTHONY J
IPC: B23B19/02
Filed: 2000-12-05
Abstract: A spindle (60) for a machine tool comprising a rear spindle portion (62) and a forward spindle portion (64) with each of the rear spindle portion and the forward spindle portion being rotatable about the same axis relative to one another. The inventive spindle includes one or more spring elements (68) extending between the rear spindle portion and the forward spindle portion whereby with the forward spindle portion and the rear spindle portion rotating at a predetermined amount and with the rotation of the forward spindle portion being constrained at that amount, an additional rotation applied to the rear spindle portion results in a deflection of the springs thereby effecting a torque between the forward and the rear spindle portions. The present invention also includes a control method which has as its objective to control the position of, not the torque applied to, one of the spindles, usually the gear member spindle. In this method, the gear member spindle position is controlled relative to the pinion member spindle position by means such as computer numerical control (CNC). As the pinion member is turned at some speed, the gear member is kept in coordination with the pinion (according to their ratio) by the CNC control. The gear member spindle can be commanded to include additional rotational components which, in effect, advance or retard the gear rotation relative to the pinion.

Patent CA-2405430-A1 (CA)
Title: Method and apparatus for increasing inkjet printing speed
Inventor: GELBART DANIEL
IPC: B41J29/393
Filed: 2002-09-26
Abstract: In an inkjet printer there is a trade off between speed and quality. Higher speed can be achieved at the expense of quality as inkjet droplets deposited are distorted in shape and or placement position if the relative velocity between the inkjet nozzles and the printing medium is simply increased. The velocity above which distortion occurs is termed threshold velocity. A feed mechanism that varies the printing medium advance rate to allow printing at below threshold velocity while maintaining a high average feed rate is described. By advancing the printing medium at a periodically varying velocity, with the printing medium velocity lower than the threshold velocity, the problem is avoided.
