Title: Exhaust connection for combined heat pump and diesel engine - has reduced area portion inside exchanger to cause high temp. and increase heat transmission
Inventor: CREDE HELFRIED DIPL PHYS
IPC: F01N3/04
Filed: 1980-01-11
Abstract: The heat pump using a diesel engine includes a heat exchanger which uses waste heat from the engine exhaust to heat up water circulating through it. The exhaust pipe is connected to a tube with an inner tube of smaller diameter which compresses the gases passing through. Water is circulated through the space between the two tubes to receive the heat from the exhaust gases.. The heated water is used for the refrigerant compressor. The compression of the exhaust gases causes a temperature rise so as to increase the heat extraction without increasing the size of the heat exchanger. This can be combined with a system to protect the entry of water into the engine due to leakage.

Title: Chemical processing pipe decarbonising method - involves adding non-angular non-abrasive particles periodically to gas blown through
Inventor: NUNCIATO DAVID JOHN
IPC: F28G1/12
Filed: 1980-05-19
Abstract: A gas inlet and outlet are formed in the pipe, the outlet being left open to atmosphere while a current of flushing gas is blown in through the inlet to remove loose, fragments, until the discharge is clean, after which impact-resistant non-angular particles having no abrasive action are introduced into a current of propellant gas in a proportion of between 0.1 and 10 kg of particles to a kg of gas. The latter is delivered into the inlet at a rate such as to give a discharge rate from the open outlet of between 1500 metres per minute and sonic speed, continuing for a time sufficient for decarbonising of the pipe. After this the introduction of the particles is stopped, the gas current continuing in order to expel loose fragments from the pipes. The operations are repeated, without causing an abrasive effect in the straight pipe runs or a chiselling one in the bends, until carbon-free discharge from the outlet indicates that they are clean. The method decarbonises heated pipes used for processing hydrocarbons or other chemicals without damaging the straight or curved portions.
