Title: Drive transmitting coupling in circular knitting machines - with piston disengaging stepwise drive of program cam to needle cylinder
Inventor: BILLI GIOGIO
IPC: D04B15/94
Filed: 1973-07-27
Abstract: In a disengageable drive transmitting coupling between the program cam drum and the needle cylinder on a circular knitting machine, the stepwise movement of the program cam is disengaged by causing a piston to lock two spring loaded cams on the coupling and release wedge rollers and the coupling. When the piston is retracted, the springs on the cams cause the rollers to wedge the coupling so that the drive is transmitted. Thus the stepwise drive of the program cam to the needle cylinder may be interrupted by activating the cylinder.

Title: Charge-state monitor for battery - sums current and voltage after correcting for change in internal resistance of battery
Inventor: KOLLORZ WOLFGANG DIPL ING
IPC: H01M10/48
Filed: 1974-08-01
Abstract: The charge-state monitor, for a battery, adds the battery's terminal voltage to the voltage drop across a series resistor connected to the battery and compares this voltage sum with a reference. The difference between the two is indicated by means of a servo-motor coupled to the comparator's output and driving a pointer across a scale. The voltage drop across the resistor is corrected by an amount that depends on the change in the battery internal resistance (due to a change in charge state). The advantage lies in taking account of the increase in internal resistance as the battery is progressively discharged.

Title: Time measuring pulse circuit - with pulse selector passing time dependent frequency pulses from pulse generator to counter
Inventor: SCHNABEL HARALD DIPL ING
IPC: G04F10/04
Filed: 1974-10-31
Abstract: A time counter for use in determining the duration of telephone calls can be produced at a reasonable cost, suitable both to measure short times with small absolute tolerances as well as long times. The pulse generator PG passes several separate pulses P1 to Pn of different frequency to the counter Z. A pulse selector circuit PA is inserted between pulse generator and counter to pass, as a function of time, only a pulse of a certain frequency to the counter so that the count rate of the counter becomes a function of the time. This makes it possible to load the counter with fast pulses when the time to be measured is short, and to feed pulses with a slower frequency during longer times to be measured.

Title: A-D converter increases resolution by random sampling - and performs stochastic analysis of resulting sample mixture without raising sampling rate
IPC: H03M1/00
Filed: 1974-11-22
Abstract: The A/D converter samples the analogue input signal at overlapping, equidistant and stochastically varied intervals, and the equidistant sampling intervals are large compared to the maximum stochastic fluctuating interval. A series of equidistant sampling intervals is followed by a sampling interval of stochastically varied length while the mixed input samples are subjected to stochastic signal analysis and they are correlated with a set of mixed reference signal samples. The system is used to enable an increase in the input resolution without increasing the sampling frequency with consequent increase of component costs. A control stage (15) contains a timer (16) a coupling stage (17) and a random generator (18).
