Title: High temperature protection for IC engine - has two stage operation to give warning before cut out
Inventor: PIKHARD JOHANN
IPC: F02D17/04
Filed: 1975-02-06
Abstract: The engine has a protective circuit supplied from the electrical system (1, 23) through a main switch (2). The supply is taken to a switching circuit (3) which has an external connection (4) to a temp. sensitive resistance element (5) at a suitable point within the engine.

Title: Automatic locomotive braking with limited manual override - has driver's control connected to AND:gate controlling converter scaling down pulses from speed transducer
Inventor: LANGE HANS-ARNIM
IPC: B61L3/00
Filed: 1976-06-14
Abstract: The automatic braking system for locomotives, with limited manual over-ride alows the train to be driven at the maximum permissible speed whilst still providing sufficient braking to bring it to rest within a minimum stopping distance. A braking signal provided by a control operated by the driver provides a fixed delay for the braking sequence set by a braking curve unit. The control is connected to an AND-gate together with the output of a limiter. The output of the gate controls a converter which scales down the pulses from the speed transducer by a factor which corresponds to the ratio of the operational braking delay to the least operational braking delay.

Title: IC engine with compression and combustion cylinders - has cylinder arranged side by side with common crank and heat insulation for combustion cylinder
Inventor: RENNER EWALD DIPL ING
IPC: F02B41/06
Filed: 1976-06-23
Abstract: The four working strokes are divided between two cylinders arranged side by side and working from a common crank shaft. The combustion air is inducted and compressed in the first cooled compression cylinder. The compressed charge is then transferred via a transfer valve (17) to the second cylinder before both pistons reach t.d.c. while the exhaust valve (19) is closed. The residue exhaust gases could be expelled if necessary by air from slots in the cylinder wall before the power piston reaches t.d.c. This process also helps to cool the exhaust valve. The second cylinder is insulated against heat losses and contains a heat storage and exchange insert (10) in the cylinder head. The combustion chamber (10a) is formed as a turbulence head and embedded in the heat exchanger.
