Abstract: The regulator is a refrigerant regulator intended for heatpumps and refrigerators. It has a built-in receiver, which automatically absorbs redundant refrigerant. It is a hermetic closed device without removable parts. It is robust and there is no need for adjustment. The regulator is composed of a heat exchanger with large heat capacity, a receiver and two pressure reducing valves. The two valves behave different on boiling fluid flow. One of them, named a heat sensitive valve, restricts fluid flow when the fluid is boiling. In the other valve, named a pressure sensitive valve, the boiling has no influence on the fluid flow. The regulator controls the refrigerant flow from the receiver to the evaporator by means of the pressure in the receiver-and the pressure in the receiver is controlled, via the heat exchanger, by the need of refrigerant in the evaporator. This way of control ensures 100% use of the evaporator, the suction gas is superheated, and the liquid from the condenser is sub-cooled. These factors improve the relation between the cooling capacity and the power consumption with more than 10%.

Abstract: A smoke detector is shown in which blue light is directed through a scattering volume ( 9 ) from a radiation emitter ( 3 ) and infra-red radiation is also directed through the scattering volume ( 9 ) from an infra-red source ( 3 A). Radiation forward-scattered by any particles in the scattering volume ( 9 ) is directed by a mirror ( 13 ) onto a photodiode ( 15 ) which produces an output to control means ( 16 ). The emitters ( 3,3 A) are pulsed at different frequencies, enabling the control means ( 16 ) to produce separate signals ( 21,23 ) corresponding respectively to the scattered blue light and the scattered infra-red radiation. For smoke particles, significantly more blue light is scattered than infra-red radiation, but this is not so much the case for non-smoke particles. A comparator ( 25 ) takes the ratio of the two signals ( 21,23 ) to produce a smoke-dependent warning output. In order to reduce power consumption and increase the life of the blue light emitter ( 3 ), the apparatus normally operates in a monitoring mode in which the infra-red emitter ( 3 A) is pulsed intensively but at a low flashing rate, and the blue light emitter ( 3 ) is maintained inoperative, until infra-red radiation scattered by particles in the volume ( 9 ) cause the photodiode ( 15 ) to produce a sufficient output, whereupon the blue light emitter ( 3 ) is rendered operative.
