Abstract: The present invention relates to a cooling unit for cooling fluid in a dry cleaning system and a method therefore. The cooling unit (12) comprises a device (1, 7, 8) containing cooled fluid such as carbon dioxide, and a tube section (11) for conveying the fluid from a first compressor stage (2) to a second compressor stage (3), arranged so that the fluid in the tube section (11) is cooled by the cooled fluid in the device (1, 7, 8).

Abstract: An indication device for a laundry washing machine, which has a treatment chamber (12) for laundry that can be pressurized in order to treat the laundry with a cleaning agent. The treatment chamber is provided with an opening (13), which in the treatment position is covered by a door (16) fixed to a surrounding housing (11) and is sealed from the housing by means of a sealing arrangement. The sealing arrangement comprises at least two gaskets (19, 20) surrounding the opening and forming an intermediate space (23) that via a channel (24) is arranged to communicate with atmosphere.

Abstract: A safety device for a laundry washing machine or the like where the washing machine comprises a treatment chamber (12) for laundry that is pressurized in order to treat the laundry with a treating agent, for instance, carbon dioxide. The treatment chamber has an inlet opening (13) which during the treatment is covered by a door (16) that is secured to a housing (11) enclosing the chamber by means of a first holder device (35) which is part of a locking means. The locking means also comprises a second holder device (34) which is activated if the first holder device (35) is deactivated and thereby keeps the door (16) in its closed position as long as chamber is pressurized.

Abstract: A solar energy conversion plant is composed of a number of conversion units. Each unit is a hot gas engine coupled to a generator. All hot gas engines are connected to common tube mains one of which contains working gas of high pressure while another contains gas of low pressure. A compressor is arranged to maintain the pressures in the mains and is separately governed.

Abstract: A closed-cycle hot gas engine heated by solar radiation is provided with a governing system varying the working gas pressure so as to vary the power output at a constant high temperature level of the working gas and--at least partly--at a constant engine speed.
