Title: Energy storing flywheel drive - has differential gear with engine driven housing and output shaft connected via clutch
Inventor: E DIPL-ING SINGELMANN DIETRICH
IPC: F16H33/02
Filed: 1973-10-06
Abstract: The purpose of the arrangement is to store kinetic energy in a flywheel during normal operation and utilise it for starting off the vehicle from standstill and for acceleration. The arrangement is fitted with a clutch-operated differential gear as a connection between the flywheel and the output shaft. The differential gear is designed in such a way that it is possible to achieve on the flywheel speeds higher than the normal operating speed when the vehicle is slowed down by braking. The increased speed represents an improved starting effect due to the higher kinetic energy stored. The clutch can be designed as a hydraulically operated friction clutch or as a hydraulic torque transmitter.

Title: IC engine ignition release impulse production method - uses co-relation of pulsations with engine operational condition
Inventor: OTT MATHIAS PROF DIPL-ING
IPC: F02P5/15
Filed: 1973-10-18
Abstract: Method for producing release impulses, the phase of which is altered dependent upon a continuously different period of the movement process and/or dependent upon the extents of control determined by the operational condition of an I.C. engine, whereby the impulse sequences corresponding to a movement period, the duration of which is less than that of the period itself, cause a release impulse to be produced at a specific build-up point. With the commencement of a period or ignition sequence, a pulsation count limited by the extents of control is measured and built up, and the impulse of a further timely subsequent sequence is measured as release sequence, and by uniformity with the first pulsation sequence built-up level, causes a release impulse to be produced.

Title: Differential press. injector burner for metal powder spraying - has powder injector fitted in branch oxygen feed channel
Inventor: HUEHNE ERWIN
IPC: B05B7/20
Filed: 1973-12-06
Abstract: Differential press. injector burner has feed channels for combustion as, O2, compressed air etc. and powder fed via separate injectors.

Title: Sync rectifier with negative feedback amplifier - has FET switch for inverting or non-inverting input signal amplifying during different period halves
Inventor: WARNEMUENDE GUENTER DR ING
IPC: H03F3/387
Filed: 1973-12-12
Abstract: The synchronous rectifier uses an operational amplifier with a negative feedback and pref. a field effect transistor switch. The input signal is amplified with inversion during a first phase (half period), and without inversion during a second phase (half period), with the same selectable gain greater than one in both cases. The amplifier input impedance is the same for both phases so that, when the amplitude of the input alternating voltage varies, no charging of a coupling capacitor separating a direct voltage superposed on the alternating input voltage by direct voltage takes place. The internal resistances for the input direct currents at the amplifier both inputs are equal with good approximation.
