Abstract: A power shift transmission having a ratio matching feature whereby the disengagement of the transmission by moving the gearshift lever to the neutral position or by depressing the clutch pedal initiates a routine in the microprocessor controlling the operation of the transmission to calculate the ratio of the rotation of the input and output shafts of the transmission and select the gear most closely matching the calculated ratio is disclosed wherein the ratio matching routine can be manually overridden by signalling a gear change with the gearshift lever. The override feature for the ratio matching routine can be permanent for each disengagement of the transmission or temporary for the running of a timer for a predetermined length of time.

At engine idling, a higher voltage is applied to the electrodes to increase the viscosity of the fluid, that is, to increase inertial mass of the flywheel so that engine torque ripple can effectively be absorbed. At engine acceleration, a lower (or zero) voltages is applied to the electrodes to decrease the viscosity of the fluid, that is to decrease inertial mass of the flywheel so that high engine torque response characteristics can stably be obtained.

Abstract: A line pressure control during a shifting operation of an automatic transmission is disclosed. Quality of each shifting operation is represented by a predetermined variable, viz, an inertia phase time during which a gear ratio undergoes a variation. When a deviation between circumstances detected upon occurrence of a shifting operation and predetermined circumstances under which a target value is set fails to fall in a predetermined range, a deviation indicative signal is generated. Upon absence of this deviation indicative signal after completion of the shifting operation, the inertia phase time measured during the shifting operation is compared with the target value and the line pressure is adjusted in response to this comparison result when the shifting operation of the same kind is to occur under substantially the same circumstances detected. In other words, the learning to adjust the line pressure is prohibited when the deviation indicative signal is present.

Abstract: Working pistons, in particular those of brake boosters, have to tolerate a considerable number of changes in stress and great forces acting on the piston. Simultaneously, it is an object to construct the pistons as light-weight as possible. Due to the considerable forces in the axial direction, it is imperative for the piston to be well secured on the guiding axis. On the other hand, the central guide's projection securing the piston in the axial direction can cause local stresses on the piston and, thus, fatigue in the material which implies a premature failure of the piston. It is an object of this invention to improve the central circumference of the piston no longer is rigidly clamped into the central guide, but rather in that the inner end and the support are designed so as to enable a swivelling motion of the piston plate without local bending stress, thereby the life of the piston being considerably prolonged.

Abstract: Apparatus, method, and product resulting therefrom in which fruit having skins, seeds, and meat is extruded through a perforated drum to provide a small particle size pulp. The pulp is immediately heated quickly to a temperature above the inactivating temperature of the discoloring enzymes of the fruit within a time period less than is necessary for the enzymes to cause discoloration. The pulping process maximizes pectin in the pulp to give the pulp a high viscosity. Particles remain in the pulp to give the pulp a good, discernible bite or mouth feel. The volatile flavors and aromas are trapped in the pulp by heating the pulp in a closed container while causing the enzymes to be inactivated with heat.
