Patent EP-0235892-A1 (EP)
Inventor: DOWNS ROBERT CHARLES
IPC: F16H59/38
Filed: 1987-01-20
Abstract: A clutch-to-clutch power-on downshift in a motor vehicle automatic transmission (l4) is effected by reducing the torque capacity of the off-going clutching device (28,30,32) to permit the transmission input speed to increase towards a target speed which it will finally attain subsequent to the shift; increasing the torque capacity of the off-going clutching device and preparing the on-coming clutching device when the input speed approaches its target speed, so that the input speed is held near the target speed by the time the on-coming clutching device is prepared to transmit torque; and concurrently applying and releasing the on-coming and off-going clutching devices to complete the shift. 
     Since the input speed is substantially at its target value when the interchange of the clutching devices occurs, a high-quality shift with minimal driveline torque disruption can be obtained.

Abstract: An electronic frequency inverter circuit receives input electrical power at a lower frequency and energizes a load circuit (35) including gaseous discharge lamps (36,37) in a range of higher frequencies. First and second semiconductors (30,31) are operated alternately by a logic circuit (40) in current mode control such that the switches operate at the higher frequency range and the frequency of current in the load circuit varies as the magnitude of said source voltage varies. The load circuit has an impedance (38) which varies with frequency such that the peak amplitude of the load current remains substantially constant despite variations in the magnitude of said source voltage to achieve a desirable crest factor for the lamp current.

Abstract: It is intended in this process that catalyst beds are operated below the solidification point of sulphur during the conversion and then regenerated by warming. In order to regenerate the catalyst beds, which are deactivated after a certain time by elemental sulphur, during normal operation with the lowest possible outlay in terms of apparatus, at least two reactors always work one behind the other in the direction of flow, and the direction of flow of the gas stream is reversed by means of multipath fittings. This process has the advantage that it needs substantially less piping, is better controllable and less susceptible to trouble.
