Title: Multicylinder supercharged IC engine - has unloaded cylinders compressing air for driving cylinders at part load
Inventor: DINGER HANS DR ING
IPC: F02B37/007
Filed: 1978-09-07
Abstract: The engine has two rows of cylinders (12, 13). The exhaust (22, 23) from each drives the turbine (16, 17) of a turbocharger (14, 15) feeding that row. At part load one row only (12) continues to drive and fuel is cut off from the other row, (13). This row then acts as compressor for the air drawn through it. A valve (27) in the exhaust of the compressor row (13) shuts off the discharged compressed air from its own turbocharger (15) and diverts it (25) to the turbocharger of the driving row. It may be added to the exhaust (25'), drive an auxiliary turbine wheel (25'''), drive the main turbine (25'') or be added to the turbocharger compressor (25'''').

Title: Sideways transporter for rolled prods. esp. bars - which are carried between two non:parallel roller tracks by row of conveyor belts driven at different speeds
Inventor: BACHERT WOLFGANG
IPC: B65G47/54
Filed: 1978-12-14
Abstract: Bars leaving a rolling mill are to be fed from one horizontal roller track(15) to a second horizontal roller track(16) where track(15) is located at an oblique angle w.r.t. track (16). The transporter consists of a row of endless chain or cable traction belts fitted with fingers or plates for pushing or carrying the bars sideways from track(15) to track (16).

Pref. the developer is retained on the carrier mainly by magnetic attraction. The distance between the 2 carriers is 50 mu m to 5mm. The developer contains min. 0.1pt. wt. organic semiconductor (I) in 100 pts. binder resin. The surface of the developer carrier, which pref. is a magnetic rotary drum of conductive material, has a coating of inorganic semiconductor (II). The process is highly effective and gives good quality copies, avoiding the usual problems of dry development with a one-component developer system.

Patent DE-2935038-A1 (DE)
Title: Constant amplitude constant frequency sinusoidal output inverter - has DC supply into rectifier bridge via resonant inductor and capacitor across bridge plus referenced outputs
Inventor: HOLTZ JOACHIM PROF DR
IPC: H02M7/497
Filed: 1979-08-30
Abstract: The circuitry supplies a constant amplitude constant frequency sinusoidal ac output from a dc source. The inverter output is very tolerant to load value changes. The output frequency of the inverter is determined by an inductor in the dc source side of the rectifier bridge and by the capacitor across the centre of the bridge and across which the output potential is formed. The current through the capacitor is formed by a relationship between bridge charging currents which are time dependent, and the output current. The ac output current and the input dc are not subject to variation caused by commutators in the 'no current' switch state since they are inverted by diode circuitry. A regulator circuit maintains the time integral of the difference between the input current and the load current to zero. The dc supply to the rectifier bridge is via an electronic switching circuit and the actual current through the capacitor is referred to the reference from a reference signal source prior to being fed to output regulator circuits. A harmonic oscillator is used to provide the references for comparison with the capacitor current.

Title: Liq. sample analysis device - with pipette carrier for adjustable motion relative to beakers and hose pinch clamp
Inventor: PIERONI MAURO DR MED
IPC: G01N35/10
Filed: 1980-05-07
Abstract: A device to measure and investigate several liquid samples, specially blood samples, draws the sample liquids in the pipettes to a level above the metered height. The pipettes are kept at a certain negative pressure as they are taken from the liquid and the pressure at all top ends of the pipettes is raised until their levels have reached the same value . The pipettes are then closed on top, hydraulically sealed by dipping the bottoms in the liquid, and the investigation is carried out while they are in this stage. This results in a higher operating accuracy and speed and is suitable for an electronic system to read the test tubes.
