Title: Pest control apparatus and method
Inventor: ELIASSON BERTIL
IPC: A01M1/20
Filed: 2001-12-18
Abstract: Arrangement and application for executing control measures against vermin either directly or indirectly via objects giving shelter to the vermin, e.g.  substrates of substances. The control measure is based on the rate of cooling the vermin, object, etc., with the help of dry snow particles to which smaller and larger sizes are allocated within a selected range of sizes and velocities are allocated within a selected range of velocities. The arrangement and the application are associated with advantages in the sense that environmentally friendly and rapid control is achieved, and in that an effectively functioning cooling system is obtained, which, by the gradual supply of snow, executes cooling through different velocities and sizes of the snow particles. Rapid cooling of a defined target can be obtained in this way. In an initial phaase the small snow particles contribute most to the cooling by sublimating and giving off cold rapidly. The larger snow particles are then used to penetrate through the gas barrier and pressure barrier that is created by the smnall snow particles, in conjunction with which cooling can be maintained or can proceed. A proportion of the kinetic energy from the reduction in the pressure of the gas is utilized to strike the target with snow particles of the aforementioned kind in an optimal fashion.

When the reproduction speed conversion is determined to be possible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to the requested level. When the reproduction speed conversion corresponding to the requested level is determined to be impossible, the video reproduction speed conversion section performs reproduction speed conversion corresponding to a prescribed level lower than the requested level, and outputs a second reproduction speed signal representing the prescribed level to the audio reproduction speed conversion section. The audio reproduction speed conversion section performs reproduction speed conversion corresponding to the prescribed level in response to the second reproduction speed signal.
