Title: Traction control for work vehicle, such as front loader
Inventor: MEISER MATTHEW E
IPC: E02F9/20
Filed: 1997-09-05
Abstract: The traction control monitors the speed of each driven wheel and compares the actual wheel speed with the optimum wheel speed, for normal traction. The differences between the actual and optimum wheel speeds generate error signals which are processed with different gain factors to control the selective braking for the wheels with wheel spin. The controls uses a PID mode of control. For utility vehicles such a front loaders, the control takes into account the mode of working of the vehicle eg. if the front shovel is being deployed, to compute the optimum wheel speeds.

Title: Optical working of functional surfaces with rotational symmetry
Inventor: DOEHLER HERMANN DR
IPC: B24B13/06
Filed: 1997-12-20
Abstract: A process for CNC machine grinding or polishing of optical surfaces involves quantitative comparison of interferometer measurements of the actual surface height at a number of reference positions across the surface with corresponding values known to be required for the intended surface, and calculation of the difference as a residual error function (RF). From the diameter, material hardness properties, tool rotational speed and applied pressure, a tool working dwell time is then calculated for each reference position. The virtual quantity of material removal is estimated by application of Preston laws and is compared with the residual error function for the total functional surface and repeated in an iterative procedure, using a new selection of reference points, until agreement is achieved. The computed tool dwell times are used as the control variable to machine the surface.
