Patent DE-2901502-A1 (DE)
Inventor: ASHER WILLIAM J
IPC: B01J13/02
Filed: 1979-01-16
Abstract: The suspended microcapsule contains essentially spherical gas bubbles which are surrounded by a single-shelled, external, liquid membrane phase and which are suspended in a dispersion phase. The liquid membrane phase is essentially non-surface-active, essentially immiscible both with the dispersion phase and with the inner gas phase, and forms an external interface with the dispersion phase, and an internal interface with the trapped gas bubbles. In this microcapsule, the numeric ratio of the thickness of the liquid membrane phase t to the square of the diameter of the external surface of the essentially spherical, single-shelled, external membrane phase d<2> is in the range from 1 x 10<-5>:1 to 1 x 10<-8>:1, if t and d are specified in micrometers. The microcapsules can be used in systems for dispensing trapped gases or for adding components to the trapped gases.

Title: IC engine with steam cylinders - compresses exhaust gas in adjacent cylinders before water injection to produce superheated steam
Inventor: STARKER KARL-GEORG
IPC: F01K21/02
Filed: 1980-05-29
Abstract: The engine has internal combustion cylinders supplied with fuel from a tank by a fuel pump and carburettor. The exhaust gas from these cylinders is transferred through ducts to adjacent cylinders where it is compressed. Water from tank is then injected into cylinders by pump so that superheated steam is formed. After the expansion stroke, the gas-steam mixture is exhausted to atmosphere by a duct. Further heat recovery is possible by heat exchangers. Some of the steam will condense and the water can be recycled to the tank.
