Title: Combustion engine with pre and main combustion chamber - in which volume of the pre chamber can be controlled
Inventor: SCHMIDT MARTIN
IPC: F02B19/10
Filed: 1974-08-28
Abstract: The volume of the pre-combustion chamber is controlled by means of a piston moved by a piston rod and eccentric which in turn is driven by a worm and wormwheel from an electric motor. The edge of the piston controls the through-flow area of a channel which connects the pre-combustion chamber to the main chamber. The shape of the overflow channel between the two combustion chambers is so that efficient combustion is achieved in all work phases of the engine. The electric motor which drives the piston in the pre-combustion chamber is electronically controlled to obtain optimum conditions. The time of ignition of combustion is electronically controlled by an arrangement which is connected to the choke spindle. The control is also dependent on the speed and temperature of the engine.

Title: Heat meter for heating systems using water - makes allowance for heat capacity variation with temperature of medium
Inventor: BRUEMMER HEINZ KURT
IPC: G01K17/10
Filed: 1975-02-05
Abstract: The meter comprises temperature measuring devices to measure the difference between the flow and return temperatures of the heating medium, a volume gauge for the heating medium, and a device which computes the emitted heat from the temperature difference and the volume. The temperature measuring devices measure the return temperature, and a device, preferably a monostable multivibrator, corrects the measured quantity of heat by means of a correction factor which depends linearly on the return temperature to allow for the variation in specific heat and density with temperature. Errors caused by variation in heat carrying capacity with temperature are thus avoided.

Title: Hydrogen sulphide/sulphur dioxide absorption - in an amino-deriv solvent, producing sulphur
Inventor: TANIMURA WAICHI
IPC: B01D53/14
Filed: 1976-01-19
Abstract: H2S and/or SO2 is removed from a gas by absorption with solvent (serving as the absorbing agent) selected from the group comprising aminoalcohol, an aliphatic amine, an alkyleneglycolamine, a polyalkylene-glycolamine, an aromatic amine, an amino acid, morpholin, primery, secondery and tert., the pH of which is 4-12, and more than two of org. bases, another org. solvent if necessary added, to precipitate elementary sulphur. The adsorption is improved by carrying-out the reaction under pressure with excess SO2 so as an unreacted portion of SO2 remains in the solvent after completion of the reaction and using said the SO2-containing solvent as the adsorbing agent. This process saves thermal energy previously required for stripping-off H2S from the solvent used for the reaction.
