Granted: 1994-04-15
Abstract: FIELD: agriculture. SUBSTANCE: incubator has heater with series-connected sections 2,3, which are normally connected to ac circuit (220 volt), and additional section 6 designed for low- frequency power supply. When alternating current is in the circuit, sections 2,6 of heater heat inner space of incubator, with voltage of section 3 being taken-off and supplied to input of rectifier 5. Accumulator 8 is recharged by rectified current. Section 3 is shunted by section 6, whose active resistance is far less. When predetermined temperature is reached, section 6 is switched-off by contact 7 of temperature regulator. As a result heat power of section 2 is reduced. In case of emergency switching of ac circuit, incubator chamber is heated by heater 6 from low-frequency source-accumulator 8.

Plate carrying layer of beta-active nuclide applied on one side is placed in focal plane of lens or concave mirror, photoemulsion layer is located on the other side. Thickness of plate is close to maximal path of beta particles of used nuclide. Beta particles generated with beta- disintegration are absorbed in plate but considerable part of electrons having higher energy and emerging with reverse beta-disintegrations initiated by neutrinos passes through plate and acts on photoemulsion. Image corresponding to distribution of neutrinos of ultralow energies appears on photoemulsion after development. EFFECT: increased quality of registration. 3 cl, 1 dwg
