Title: Subtraction circuit for serial subtraction of BCD 8421-coded decimal digits
Inventor: MERKLE PAUL
IPC: G06F7/50
Filed: 1988-12-27
Abstract: The serial subtraction circuit according to the subject of the invention consists of a dual full subtractor (1), in which the subtrahend tetrad is serially subtracted from the minuend tetrad, and a correction circuit (5), using which the number 6 (LHHL) may be subtracted from the intermediate result number, which is stored in the shift register (3). The intermediate result number is lowered by the number 6 (LHHL) in circuit (5) if the output (s2) has high potential after the fourth clock cycle, and not lowered by the number 6 (LHHL) in circuit (5) if the output (s2) has low potential after the fourth clock cycle. Thus the possibly corrected intermediate result number can be input in parallel via the gate circuit (6) into the shift register (4) on the fifth clock cycle, on which the shift register is not controlled by the cycle. Circuit (5) is a subtraction circuit for the number 6 (LHHL), and consists of four dual half subtractors. <IMAGE>

Title: Rotary piston compressor with selective cylinder loading - has load chamber for each cylinder in four-cylinder engine with output thrust additionally enhanced by varying transmission
Inventor: ELLSAESSER DIETRICH GERHARD
IPC: F04C29/12
Filed: 1990-03-15
Abstract: The mechanically driven supercharger has an outer runner which has ports (1-4) in its outer wall which are laterally displaced in relation to each other. The four fit onto an outlet connecting piece which is divided into four parts, so that with each rotation of an inner runner each chamber discharges into a separate outlet. In this way, each chamber conveys the compressed air in a four cylinder engine always to a predetermined cylinder in a discharge impulse. The charger is driven by components which deviate from the circular form, such as gearwheels, and this means that the speed of the charger varies relatively to that of its drive. USE/ADVANTAGE - Supercharger for four cylinder two-stroke IC engine to provide an increased gas exchange speed.
