Title: Non-linear function generator - using sequence controlled resistor switching gives weighted switching of resistors within cycle period
Inventor: ZWACK EDUARD ING GRAD
IPC: H03K4/02
Filed: 1974-08-30
Abstract: A non-linear function generator allows a specific characteristic to be generated over a specified time period based upon discrete switching over a number of time increments. The inverter input of an operational amplifier has a capacitor coupled between input and output and is controlled by a sequence control circuit switching resistors. Over the first half of the cycle period the resistance values are increased by a factor of two for each sequencing step. Over the second half of the cycle period the resistance are decreased by a factor of two. The resistance switching determines the non-linear function characteristic that is generated. Additional outputs provide overall cycle control.

Title: Combined brake and venting valve for pneumatic brakes - has balanced area valve elements to provide pressure-independent operation
Inventor: VOLLMER OTTO
IPC: B60T15/04
Filed: 1975-02-27
Abstract: The pneumatic brakes are fitted with a combined brake and venting valve which connects the brakes either to the brake pressure supply, or vents them to atmosphere. The brake valve seating is closed from both directions by the input and venting valve elements. The input valve element is fitted with an extension in the shape of a tubular section. This has an outer diameter equal to the inlet brake element so that the inlet valve element is balanced on both sides by the residual pressure in the brake valve. Likewise the inner diameter of the extension is equal in area to the venting valve element so that the pressures are balanced across this element. The valve thus acts with a minimum of hysteresis lag, independent of any supply and residual pressures.
